2009-11-28 09:33 tim Corrected the symbol.tcl script so that "make matching symbol" will produce an error message if the page name is undefined, and will use the page name as the symbol name if the popup text box has a blank entry.
Also: (and one more small correction to put the page name into the dialog box)- posted: October 22, 2009 at 2:40am version: 3.6 revision: 163
2009-10-21 19:11 tim Partial implementation of multiple-element edit. This function allows multiple polygons to be selected and stretched simultaneously. It is a "partial" implementation because xcircuit as yet does no checking for which point of a polygon is intended to be stretched, and assumes that all selected polygons are similar. This method has not been extended to curves, arcs, or paths.
Also: Made a small correction which improves upon the guessing of which point to choose in a multi-polygon stretch, but I have a better implementation in mind. . .- posted: September 24, 2009 at 2:40am version: 3.6 revision: 162
2009-09-23 05:50 tim Changed the behavior of the file load routine to check for empty (zero size) files, and treat them as a declaration of a new document rather than attempting to read them and thus producing an error. Idea suggested by Svenn Bjerkem.- posted: July 31, 2009 at 2:40am version: 3.6 revision: 161
2009-07-30 06:48 tim Minor fix to SVG output---overlines and underlines were not being repositioned relative to the vertical justification of the text.
Also: Corrected one more simple but egregious error in the SVG output, which was writing out the text transformation matrix before adjusting it for flip invariance.- posted: July 30, 2009 at 2:40am version: 3.6 revision: 160
2009-07-29 13:29 tim Corrected two errors in the SVG writing code that addressed allocated arrays out of bounds.- posted: July 16, 2009 at 2:40am version: 3.6 revision: 159
2009-07-15 16:28 tim Correction to prevent printing negative values into Unicode character specifiers. Also, added the option "svg -full" to generate a page with width and height set to "100%" rather than physical units; this lets applications such as Firefox expand the drawing to fit the page, rather than forcing it to a printed page size (which is usually too small for screen viewing).- posted: July 15, 2009 at 2:40am version: 3.6 revision: 158
2009-07-14 09:18 tim Another modification to SVG---changed the top-level width, height, and viewbox so that the "width" and "height" values specify the overall scale of the drawing, and the drawing can be imported correctly into gimp and other tools supporting SVG.
Also: One last change to remove the "xml" line at the top of the SVG output, which is unnecessary.
Also: Okay, really the last change for today (!)---added filename and xcircuit version to the description block in the SVG header.- posted: July 14, 2009 at 2:40am version: 3.6 revision: 157
2009-07-13 12:35 tim Extended the base-36 number conversion so that component indexes up to 99999 will be converted properly (the previous version would display base-36 values for index numbers above 99; e.g., 100 = "A0"). Thanks to Bliss Carkhuff for pointing out this irregularity.
Also: Oops. . . missing the return value from convert_to_b36().
Also: Hacked in support for overlines and underlines in SVG using line drawing, since many (most?) tools don't seem to support the "text-decoration" element. Added support for PostScript standard encoding and ISO Latin-1 encoding in SVG.- posted: July 11, 2009 at 2:40am version: 3.6 revision: 156
2009-07-10 08:43 tim Added handling for transparent and opaque color stipples (which is handled by opacity and color blending, producing a better effect in SVG than one can get in PostScript).
Also: Added image handling to the SVG output.
Also: Added a menu item "File->Export->Export SVG" to generate SVG output from the current window view. Added support for text super- and sub-scripts. Added overline and underline support, but like the symbol font, this is not viewable in Firefox and may need a workaround.- posted: July 9, 2009 at 2:40am version: 3.6 revision: 155
2009-07-08 08:18 tim More corrections/additions to the svg output, including proper handling of arcs with segment lengths > 180 degrees, handling of dashed and dotted lines, and handling of text (except for a few unfinished items such as sub/super- scripts, under/over-lines, and maybe a few others).
Also: A few more SVG things: Handling of ampersands in text; removed page bounding box from the output drawing (by using the "visibility" property). The "svg" command now takes an argument for a filename other than the default (which is the page label + ".svg").
Also: Added title of page as the ID of the top-level SVG element.- posted: July 8, 2009 at 2:40am version: 3.6 revision: 154
2009-07-07 08:47 tim Added new file "svg.c" for generating SVG output, and added a new command "svg" (as yet, no arguments) that generates a .svg output file. At present, only a few basic things like simple line drawing is supported. But it's a start.
Also: First minor set of corrections to SVG: Corrected color format.
Also: Added path handling.- posted: June 24, 2009 at 2:40am version: 3.6 revision: 153
2009-06-23 11:50 tim Corrected a problem with the new recursive area selection mechanism, which is that we do not want to select things that are invisible, like info and pin labels on levels below the hierarchy top. Thanks to Bliss Carkhuff for pointing out this error.
Also: Also: Added callback functions the window creation procedure to XCOps(callback), which can be used to set up, for example, a new personalized menu in xcircuit that will be added to each new window.- posted: June 21, 2009 at 2:40am version: 3.6 revision: 152
2009-06-20 13:48 tim I made a change to the area selection a few revisions ago such that an object instance would be selected if its centerpoint is selected, where previously it would be selected if its origin is selected. However, neither method is particularly satisfying. So I have changed the area selection routine to a recursive version wherein the rule is that if any element inside an object instance is selected by the area selection, then the whole object instance will be selected. This behavior makes the area selection of large objects with empty interiors (such as sheet borders) work more like the standard single-point-based selection.- posted: May 23, 2009 at 2:40am version: 3.6 revision: 151
2009-05-22 11:44 tim Corrected an error that prevents "make matching symbol" from working if the schematic does not contain a SPICE-style ".subckt" info label line.- posted: May 21, 2009 at 2:40am version: 3.6 revision: 150
2009-05-20 07:19 tim Corrected the Makefile to use LD_RUN_PATH when compiling xcircexec; otherwise, some systems will not run "xcircuit -noconsole".- posted: May 5, 2009 at 2:40am version: 3.6 revision: 149
2009-05-04 13:06 tim Implemented Wim Vereecken's fix for popup windows in window managers that prohibit focus stealing, using the "wm group" command option.- posted: May 2, 2009 at 2:40am version: 3.6 revision: 148
2009-05-01 09:17 tim Corrected an error that causes a crash when attempting to force a page filename to a null string, as happens when clicking on the "subcircuits" button at the top of the output properties window. Also, changed the area search method for instances to use the true center of the instance, not the origin. Most objects are made with the origin in the center, but this is not necessarily true, and when it isn't, the area selection becomes very confusing.- posted: April 30, 2009 at 2:40am version: 3.6 revision: 147
2009-04-29 10:09 tim Corrected a mistake in the last round of bug fixes which prevented the linewidth prompt dialog box from appearing due to a syntax error.- posted: April 25, 2009 at 2:40am version: 3.6 revision: 146
Corrected a number of minor but annoying errors that I have not been able to get around to fixing for a while. Fixes include: (1) Proper "undo" with respect to join/unjoin, (2) Proper undo series finish for text and element size change, (3) New feature to actively update the dialog window for linewidth and scale changes, (4) New button "Apply" for the dialog window to apply a change without popping down the window, (5) Fixed problems relating to periods in filenames, including the inability to match a filename with other pages having the same (almost) filename, and the recent tendency to copy the file extension into the page label, (6) Fixed problem with parameters not appearing in the window when the parameter window first pops up, (7) Fixed the parameter window so that the value entry field grows with the window.- posted: January 9, 2009 at 2:40am version: 3.6 revision: 145
Changed the behavior of "GetPositionFromList" to check if the position list may be nested inside another list of length 1, which is the case if the list is passed as a variable, for example. Thanks to John Barry for bringing this to my attention.- posted: December 18, 2008 at 2:40am version: 3.6 revision: 144
Corrected an error in which font scale specifiers get written an extra time to the output, such that rewriting the file many times will keep growing the size of the output file. This has no immediate adverse effects, but certainly is undesirable behavior. Thanks to Benoit Bidoggia for finding this rather subtle error!- posted: November 5, 2008 at 2:40am version: 3.6 revision: 143
2008-11-04 05:57 tim Finally, after many years, created a text file import tcl script to match one I wrote long ago for the python interface. Modified the filelist filter to accept an empty string as a wildcard (matches everything, instead of matching nothing).- posted: October 16, 2008 at 2:40am version: 3.6 revision: 142
2008-10-15 10:43 tim Corrected an error in which, if a number of elements is selected, and one attempts to do an "edit" operation on a non-selected element, xcircuit crashes.- posted: September 27, 2008 at 2:40am version: 3.6 revision: 141
2008-09-26 17:45 tim Corrected code that prevented color from being changed on an element with parameterized color.- posted: September 26, 2008 at 2:40am version: 3.6 revision: 140
2008-09-25 05:46 tim Corrected the behavior when writing expression parameter values into the output file. There is no way to "second guess" an expression parameter result, so you can't really check to see if the instance value is or is not equal to the default value. Case in point: the command "page" is not defined for objects, and the result of the command returns whatever was the last top-level page viewed. Thus, an object with an expression parameter "page" will evaluate the same for the instance and the default. Clearly what's intended in that example is for each instance to print out the page number it's on. Commands using a date string are even worse, because the timestamp is sometimes the same for the default, and sometimes different as the seconds field changes. Thus, the only real solution is to always print the instance value of any expression parameter.
Also: Made a change to the "page filename" command so that it handles extensions exactly like the savefile() routine, adding ".ps" to filenames without any existing extension. This allows expressions to act on the file itself, such as "file atime [page filename]", without having to cope with the presence or lack of an extension in the returned string. Also, suspended selections during object drawing so that expressions won't attempt to access the selection in the wrong context.- posted: August 1, 2008 at 2:40am version: 3.6 revision: 139
2008-07-31 17:23 tim Corrected an error that causes a crash if one goes to a library page while one of several editing operations (wire, box, etc.; those that have associated event handlers attached to mouse movement) is in effect.- posted: July 19, 2008 at 2:40am version: 3.6 revision: 138
2008-07-18 20:27 tim Updated Wim Vereecken's matgen.tcl from version 0.5 to version 0.7.- posted: July 7, 2008 at 2:40am version: 3.6 revision: 137
2008-07-06 11:22 tim Added /usr/share/tcltk to the search path for Tcl and Tk in the configure script, to conform to the Ubuntu Linux distribution.- posted: July 3, 2008 at 2:40am version: 3.6 revision: 136
2008-07-02 20:57 tim Corrected a minor error in which over/underlines canceled by a font change (to the current font) rather than an explicit "noline", lose the line cancelation upon reading the file back into xcircuit.
Also: Made a number of minor changes in order to allow a parameterized "page X of Y" label at the bottom of a page: 1) corrected the command "page links sheet" to return the correct sheet number (X); 2) prevented the tag callback for "page" from infinitely recursing; 3) set the page during output printing so that "X" gets printed correctly in the output for each page.- posted: June 26, 2008 at 2:40am version: 3.6 revision: 135
2008-06-25 21:00 tim Corrected the popup-prompt window for setting linewidth so that it works correctly when multiple windows are present. Unfortunately, the same change needs to be made to several dozen such popup windows.
Also: Corrected the LaTeX-labels code (again) so that any overall scaling of the xcircuit drawing will translate to the end result---whatever xcircuit says the size of the drawing is, will be the size of the drawing in the LaTeX document. LaTeX labels are scaled and positioned accordingly. Thanks again to Alex Tercete, and there will probably be more extensions to come.
Also: And one more change to the LaTeX output, so that XCircuit honors label size changes, and more closely matches LaTeX label "normalsize" to XCircuit's label size 1.0 (LaTeX "normalsize" was supposed to be the basis of XCircuit's unit scale, which makes me wonder how I got off by a factor of 1.2. . .). As yet, label rotations and color are not handled.
Also: And finally, handling of rotated text. That is all I'm going to do for tonight. However, sometime I should make sure that all scales and rotations are referred to the top-level, when LaTeX text is buried in an object instance.- posted: June 24, 2008 at 2:40am version: 3.6 revision: 134
2008-06-23 08:31 tim Corrected an error, pointed out to me by Orestes Mas, preventing "snap space" and "grid space" from being executed from a window.- posted: June 23, 2008 at 2:40am version: 3.6 revision: 133
2008-06-22 21:18 tim Changed the LaTeX mode output according to Alex Tercete's solution of using \scalebox{} and \parbox{} around \includegraphics{}, which allows the LaTeX output to track the "scale" setting in the xcircuit output, scales both text and graphics at the same time, and avoids requiring declaring the "epsfig" package. Thanks, Alex!- posted: June 5, 2008 at 2:40am version: 3.6 revision: 132
2008-06-04 22:50 tim Corrected an apparently not-previously-reported error that causes a crash due to an out-of-bounds index into the fonts array. This may be a pathological condition, as it was found by accidentally reading a file produced by a newer version of xcircuit into an older executable. However, this does highlight the need for some version checking to avoid this kind of error.- posted: May 16, 2008 at 2:40am version: 3.6 revision: 131
Changed the "package require -exact" to "package require" in tkcon.tcl, so that xcircuit will work on Tcl/Tk version 8.5.- posted: February 5, 2008 at 2:40am version: 3.6 revision: 130
Corrected filename expansion so that tilde-prefixed filenames are treated as full paths and not appended to the search path prefixes when looking for input files.- posted: January 18, 2008 at 2:40am version: 3.6 revision: 129
Updated Wim Vereecken's matgen.tcl to version 0.6.- posted: January 7, 2008 at 2:40am version: 3.6 revision: 128
2008-01-06 09:06 tim Made some corrections to the non-Tcl version to prevent crashes due to NULL filename entries. There may be other places where this crops up, but at least it will save a file properly.
Also: 2008-01-07 02:40 tim- posted: September 24, 2007 at 2:40am version: 3.6 revision: 127
2007-09-23 12:00 tim Several corrections: 1) Corrected an error in "findcurfont" that could crash xcircuit if an expression parameter returns an error result, and the resulting string part is NULL. 2) Corrected an error that allowed degenerate (single-point) polygons to remain, if the polygon were edited and all points placed on top of each other. 3) Corrected an error that prevented using "undo" on any arc that was edited to zero radius (the element was deleted rather than being placed on the undo stack). 4) Removed a few more direct Tcl_Eval calls to GUI functions, replacing them with "XcInternalTagCall()" calls.- posted: September 22, 2007 at 2:40am version: 3.6 revision: 126
2007-09-21 23:38 tim Corrected a few problems with the parameter value edit box; namely, that 1. The choice-list box should lower itself when a selection has not been made (still, there should be a way to cancel it. . .); 2. Expression parameters that are *not* choice-lists should make it into the edit box, except that 3. they should be printed as the expression itself (-verbatim option), not the expression result.- posted: September 18, 2007 at 2:40am version: 3.6 revision: 125
2007-09-17 09:20 tim Corrected the "tech replace all" command as called from the "File Load" GUI, which was calling it as "tech replace any", and therefore not working.
Also: Corrected an error that was producing a spurious Tcl error message when executing "Load Dependencies". The result value was not a TCL result type, and there wasn't any error.
Also: Corrected a slew of errors in large project handling. These changes include: 1) Force a write of technology files when doing "Write All" and choosing "Force" 2) Added "technology used" option to find all technology files to which objects that are descendents of the page belong. 3) Added "technology changed " to force technology files to be marked as changed or unchanged (previously this was only possible with pages). 4) Corrected the handling of the technology "writable" flag on input, which was looking at the last technology created rather than the technology belonging to the input file, so files containing objects with multiple technology prefixes would get the writable flags all screwed up. 5) Do not follow symbol-to-schematic links that were made through the "link" parameter. In particular, this means don't collect such links and force all the filenames to be the same. 6) Related to (5), added "file links linked" as an option which finds pages linked via the "link" parameter. The other "file link" options now specifically do *not* list pages linked through the "link" parameter, to get the behavior of item (5).
Also: Changed the symbol.tcl file to make "index" the default parameter key for a component index rather than "idx".- posted: September 15, 2007 at 2:40am version: 3.6 revision: 124
2007-09-14 13:58 tim Added Wim Vereecken's "matgen" function for importing Matlab scripts (now if it can only be translated into gnuplot output from Octave!). Also, rearranged some of the startup functions so that functions imported from outside scripts like this one will get put into the menus of all secondary windows. Finally, rearranged the menu such that all import functions appear as a secondary "Import" menu under the "File" main menu.- posted: September 14, 2007 at 2:40am version: 3.6 revision: 123
2007-09-13 19:45 tim Added patch by Wim Vereecken that fixes the weird behavior where "color add" always returns the highest index in the color list, even when the color already exists in the color table and therefore has a different index from the one returned. This functionality had been implemented with "color index ", but it seems inappropriate to let "color add" return an incorrect color index. Now "color index" and "color add" are effectively redundant options. - posted: September 12, 2007 at 2:40am version: 3.6 revision: 122
2007-09-11 09:15 tim Corrected a bug introduced by attempts to clean up the "Make Matching Symbol" function. The bug strips the technology name off of objects when they are created. Thanks to Dimitri Princen for the bug report.
Also: Corrected the function that changes corresponding pins in a symbol vs. its schematic, which was also incorrectly changing corresponding pins between a schematic secondary page and its primary.- posted: September 11, 2007 at 2:40am version: 3.6 revision: 121
2007-09-10 11:07 tim Another several corrections to indirect parameter handling. (1) The eparamptr structure now contains an extra byte with a bit flag reporting if the parameter is indirect or not. This allows object instances to have parameterized position and rotation; otherwise, there is a conflict; and (2) corrected the output name of indirect parameter references to match the new system of prepending "@" to such names to avoid conflicts with defined PostScript keywords.- posted: September 10, 2007 at 2:40am version: 3.6 revision: 120
2007-09-09 12:20 tim Corrections to text_regexp, auto-increment, and undo: Added an "undo series" command to allow Tcl prodedures to act as monolithic blocks with respect to the "undo" mechanism. Changed text_regexp and auto-increment to make use of this function, so that blocks of label selections that are changed at once get undone at once.
Also: Corrected an error which left a corrupted "undo" stack when an element was copied on top of itself. This action would delete the duplicate element to prevent the problem of having invisible multiple elements screwing up a netlist. However, previously the duplicate was deleted instead of being transferred to the undo stack.
Also: Made a small change in the netlister that allows parameters to be cross-referenced between a symbol and schematic, using indirect parameters. For example, take an nMOS symbol with parameter "width", used in a schematic "inverter". In the inverter, the nMOS parameter is indirectly linked to a parameter called "scale" in the schematic of "inverter". The symbol for "inverter" also contains a parameter called "scale". If a top-level schematic uses symbol "inverter" and gives it a parameter value scale=2, then a flat netlist format will transfer the value of "scale" in the inverter to "width" in the nMOS. The subtleties of this method will be hammered out in the tutorial.- posted: September 9, 2007 at 2:40am version: 3.6 revision: 119
2007-09-08 21:25 tim Dimitri Princen corrected the new GUI window for parameter modifications to include the ability to handle multiple-selection Tcl expression parameters, in the listbox, which is a nice way of handling it.- posted: September 8, 2007 at 2:40am version: 3.6 revision: 118
2007-09-07 12:37 tim Several more corrections: The technology name was still getting attached to the schematic name when using the "associate" function. Also, corrected the auto-increment routine so that it doesn't generate an error when a selected label doesn't contain any numbers to increment.
Also: 2007-09-08 01:08 tim Added Dimitri Princen's enhancements to the parameter edit window (namely, embedding the parameter entry widget in the same window as the parameter list). Also, created a popup window for text modification, including search-and-replace and a general-purpose number increment/decrement.- posted: September 6, 2007 at 2:40am version: 3.6 revision: 117
2007-09-05 11:30 tim Corrected an error that prevented the netlist from being destroyed and recreated when the netlist is invalidated on a secondary page of a multiple-page schematic. This would lead to a corrupted netlist and quickly cause a crash.
Also: Also: Corrected the crash recovery file read-in to correctly terminate the filename string; otherwise, the filename can end up with extra characters at the end.
Also: Also: Corrected another error that attempts to look for filenames beginning with "/" in the file search path, rather than in an absolute path. This prevented crash recovery files from being found and loaded.
Also: Also: Corrected the schematic-to-symbol switch so that selected elements can be transferred from one to the other during a move or copy command. Note that the schematic-to-symbol switch is not handled by the "undo" mechanism, although it should be!
Also: Proper correction to the problem of having the technology name copied over to the schematic. The previous claimed fix of this problem didn't solve it.
Also: Corrected the error that occasionally prints "Use of non-numeric characters in component. . .". This was due to having the occasional instance value copy the "?" from the default value. I'm not sure how the instance value gets that way without passing through resolveparams() and getting eliminated, but presumably no harm is done by its being there.- posted: September 5, 2007 at 2:40am version: 3.6 revision: 116
2007-09-04 17:29 tim Added a Tcl script for doing regular expression substitution into a text label (or all selected text labels, or all text labels on a page).- posted: September 2, 2007 at 2:40am version: 3.6 revision: 115
2007-09-01 15:05 tim Corrected an error that causes xcircuit to segfault if "X" (exchange) is typed with no selections made. This happened to me when I inadvertently reached too far when going for the "Z" for zoom.- posted: September 1, 2007 at 2:40am version: 3.6 revision: 114
2007-08-31 11:00 tim Added John Barry's code for drawing small dots in the grid color around 20x snap spacing points. Also: Another correction to the symbol generation, which failed to add the namespace separator "::" between the technology name and the symbol name when generating symbols.
Also: Corrected some errors with link dependency loading. The routines now use the instance value of the "link" parameter, if it is different from the default, and reports an error on failure to load the file.- posted: August 31, 2007 at 2:40am version: 3.6 revision: 113
2007-08-30 12:31 tim Corrected the "symbol.tcl" script that creates matching symbols for schematics. The handling of label selections had changed, leaving labels selected after justification. This likely needs to be changed in the tclxcircuit.c code; for now, I'm adjusting the script to cope with the change.
Also: Modified the netlisting so that device indices that are specifically set will be honored when generating the slash-separated hierarchical names for internal nodes. For example, if cell "decoder" is given an index parameter value "4", then nodes in this cell will be prefixed with "decoder_4", instead of some unrelated number, which was the prior behavior. This is particularly important if a netlist is being generated by concatenating results of different netlist formats. Also modified the index generation for devices in flat netlists such that the numbering is independently counted for each device class. This is a minor enhancement, but comes in handy when one is searching in the netlist for the first resistor and can't find any reference to "R1", because after writing out 45 other devices, the first resistor was given the index "R46". Also: another correction to the automatic symbol generating code, to ensure that the new symbol gets the technology type specified in the dialog box. Otherwise, new symbols end up in the user space always.- posted: August 26, 2007 at 2:40am version: 3.6 revision: 112
2007-08-25 08:09 tim Implemented a bug fix by Dimitri Princen, fixing the error where attempting to change font style one character into a text label would (at best) fail to work and (at worst) crash the program.- posted: August 21, 2007 at 2:40am version: 3.6 revision: 111
2007-08-20 20:23 tim Corrected the output of "config pinpositions" and "config bbox" to return the words "visible" and "invisible" rather than "true" and "false"; otherwise, the GUI checkboxes are not updated properly, and it becomes impossible to change the settings again from the GUI. Thanks to Dimitri Princen for the bug report.- posted: August 9, 2007 at 2:40am version: 3.6 revision: 110
2007-08-08 22:54 tim Corrected the call to memset() with the patch from Chitlesh Goorah.- posted: July 18, 2007 at 2:40am version: 3.6 revision: 109
2007-07-17 21:40 tim Implemented Dimitri Princen's fixes and enhancements for the "raise" and "lower" functions. "lower" would cause an element to be lost in certain situations, and has been corrected. The TCL "element raise" and "element lower" commands now respect the order of elements in a group when a group selection is raised or lowered. Also, finished the implementation of "drag and drop" between multiple xcircuit windows. This does not work in "hold" modes (which lock focus on the window where the button was pressed), but will work in the toolbar "move" and "copy" modes. In finishing this implementation, I also fixed an error that causes the initial position of an element to be incorrect when moving between pages, objects, or windows (this was generally not very noticeable because the position would correct itself after any mouse motion).- posted: June 29, 2007 at 2:40am version: 3.6 revision: 108
2007-06-28 21:30 tim Corrected an error in the tag callback mechanism that would hang the program if a command with non-escape percent signs was passed to the tag handler (e.g., an info label "make" statement with its own percent escapes. This causes, for example, the "read EDIF" command to fail).- posted: June 25, 2007 at 2:40am version: 3.6 revision: 107
2007-06-24 23:10 tim Finished the code to generate new xcircuit windows by adding the capability to regenerate the color and font menus in each new window. Removed this item from the TODO list, and added some others that I have been thinking about lately.- posted: June 21, 2007 at 2:40am version: 3.6 revision: 106
2007-06-20 13:16 tim Corrected an error in setallstylemarks() which incorrectly used strcat() instead of strcpy() to write into an uninitialized character array. Thanks to Dimitri Princen for finding and fixing the bug!- posted: June 20, 2007 at 2:40am version: 3.6 revision: 105
2007-06-20 00:10 tim A number of corrections to the updates from the last few days. There is still a crash-causing bug lurking about. Beware!- posted: June 19, 2007 at 2:40am version: 3.6 revision: 104
2007-06-18 08:43 tim Applied a fix from Dimitri Princen for a bug that will cause spurious segmentation violations on any system that defines "Boolean" as anything other than "int".
Also: Added missing icon.- posted: June 18, 2007 at 2:40am version: 3.6 revision: 103
2007-06-17 08:43 tim Numerous things in this revision: Added the "preselected" method to the appropriate actions (rotate, flip, move, exchange, rejustify, etc.) (see notes on last commit). Also: Added an interactive rescale method and a toolbar button to go along with it. Also: Extended the "unjoin" method to cover what was previously handled by the "x" key in edit mode for polygons, to break a polygon at a specific point. The "unjoin" command will break the polygon at the point closest to the pointer position.
Also: 2007-06-17 16:06 tim Also: Corrected an error in file read-in in which parameter substitutions were made on the wrong object when comparing two objects.
Also: 2007-06-18 00:04 tim- posted: June 17, 2007 at 2:40am version: 3.6 revision: 102
2007-06-16 07:35 tim Partially implemented a new method in which elements that are selected prior to certain actions (rotate, flip, move, etc.) remain selected after the action has finished. This should satisfy the several people who have complained that element group rotations are difficult because the elements get unselected after each rotation step.- posted: June 16, 2007 at 2:40am version: 3.6 revision: 101
2007-06-15 09:41 tim Added auto-positioning of popup windows when they appear, to be centered on the pointer position, and adjusting to prevent off-of-screen positions. Windows that already exist are not repositioned.
Also: 2007-06-15 11:03 tim- posted: June 15, 2007 at 2:40am version: 3.6 revision: 100
2007-06-15 00:17 tim Cleaned up most of the interaction between the command-line interface and the GUI, removing direct references to the GUI from the C code. Check- and radiobuttons now work correctly for border styles, fill styles, color, fonts (all aspects), and options. Check boxes are no longer left in an incorrect state after an element is deleted.- posted: June 13, 2007 at 2:40am version: 3.6 revision: 99
2007-06-12 15:57 tim Corrected an error in which the edit cycle of a polygon was not reset after editing, causing bizarre behavior in "pinattach" mode.
Also: Also: Added more tag callback handling to set GUI check- and radiobuttons to reflect changes made by the command line or startup code. Changed the "label" command such that "label justify" (without any selections made) returns a two-word answer reflecting the horizontal and vertical justification settings.
Also: More (mostly transparent) changes: Trying to get all GUI-specific calls out of the C code. To this end, removed all of the config and label calls to Tcl_SetVar2 from menucalls.c and moved the original GUI functions into xtfuncs.c (where all of the Xt GUI calls reside). Tag callbacks for "config" and "label" in the wrapper script now handle the Tcl variable setting (to-do: "color", "border", and "fill" commands).- posted: June 12, 2007 at 2:40am version: 3.6 revision: 98
2007-06-11 23:31 tim Miscellaneous bug fixes, including a few involving the ISO-Latin2 through 5 encodings (thanks to Ahmet Nurlu for the bug report), and a fix of the "LED" library object to match yesterday's changes to the expression parameter syntax.
Also: Also: Corrected a bug noted by Dimitri Princen that allows two substrings to be parameterized under the same parameter key.- posted: June 11, 2007 at 2:40am version: 3.6 revision: 97
2007-06-10 20:14 tim Changed the notation for parameters used inside Tcl expressions from "%" to "@", because the former is interpreted by PostScript interpreters (e.g., ghostscript) as a comment line and causes an immediate failure of the output rendering.
Also: Another correction allowing parentheses after parameters in expressions.
Also: Final change for parameterized points---splines, polygons, and paths get any parameterized point positions recalculated on the fly during edit mode, so that constrained points cannot be edited.- posted: June 8, 2007 at 2:40am version: 3.6 revision: 96
2007-06-07 20:49 tim Added a tag callback to "config" to allow configuration changes made from the command-line or startup script to properly set the checkbox in the GUI window. Also, added an escape "%#" to tag callbacks to pass the number of arguments given to the original command. This allows tag callbacks to more easily handle such situations as the above, where "config
- posted: 12/19/05 version: 3.5 revision: 5
Added command option "objectlibrary [ ]" where the final optional argument was previously unavailable. If present, the final argument declares a new library for the object. If not present, the number of the library containing the object is returned.
Also: Corrected lib/tcl/symbol.tcl where the "%n" was missing from the end of the subcircuit call statement.- posted: 12/14/05 version: 3.5 revision: 4
Fixed an error in netlisting which causes the netlister to write "X.." lines in the SPICE output of "trivial" symbols like the "dot" object.- posted: 12/13/05 version: 3.5 revision: 3
Fixed another fatal error in file writing due to having a NULL filename.
Also: Revised the Wprintf() calls to accept variable argument lists, rewrote the Tcl versions of W*printf() as calls to a script rather than being hard-coded as a specific Tk function. This allows me to rewrite the script equivalent of Wprintf() to print to both the message widget and the console output, so the console now gets a complete record of warning, error, and informational messages produced by xcircuit.
Also: Fixed two fatal errors with "Load Dependencies", one which crashed xcircuit due to a typo in the Tcl code for command "page links load", and the other which created an infinite loop if loadfile() failed to load a file inside the recursive call to "page links load".- posted: 12/8/05 version: 3.5 revision: 2
Corrected a behavioral error in which xcircuit does not generate netlist output for a symbol containing an info label but no pins. Thanks to Herman Lee for pointing out this problem.
Also: Corrected a problem in 3.5.1 in which xcircuit changes filenames in a multi-schematic session to match the top-level schematic. It ignored the setting of "dmultiple", and thus would make changes without warning when it generated the crash backup file, for example.
Also: Added a widget for managing multi-schematic file writes, with a menu hook from "Files->Write All...".
Also: Changed the behavior of "page changes" to include change counts of all descendents. Fixed the Tcl parsing of the "page" command for certain options when a page is specified in the command (e.g., "page 1 fit"). Modified the "page changes" command so that the change count can be altered, thus forcing a page to be recognized as either modified or unmodified.- posted: 11/21/05 version: 3.5 revision: 1
Separated the source code into distribution (version 3.4) and development (version 3.5) branches, on the suggestion of Zvezdan Petkovic.
Also: Added command option "page changes" which reports the number of changes on a page. Modified some behavior so that starting certain commands like "copy" does not increment the number of changes, so that the command can be canceled without xcircuit thinking that the page has been modified.
Also: Added command option "config search file|library" with a colon-separated list
, specifying the search order on a specific set of directories. These lists are initially null, and behavior remains the same as before while these lists are null. A non-null search path overrides the default search on the current working directory, and a non-null library search path overrides the search on XCIRCUIT_LIB_DIR and the default install directory path. Modified the library manager to use search paths.
Also: Allow "library load" on a regular xcircuit (.ps) file, which has the behavior of loading the objects from the file without loading the pages themselves. Also: Added command option "netlist get -hier" to generate a slash-separated hierarchy using device names and indices.
Also: Fixed "netlist goto" to accept the same syntax that is produced by "netlist get -hier", and finished the coding of the routine.
Also: Added command options "netlist select" and "netlist position ".
Also: Changed behavior of the "%" macro so that it also raises the console to the top of the window.
Also: Added command option "netlist parse" (e.g., "netlist parse spice") that allows some selective parsing from a Tcl script.
Also: Created a script called "symbol.tcl" that replaces the function of the "Make Matching Symbol" button in the xcircuit menu, with a considerably fancier interface.
Also: Modified the command "color set" to accept color names.- posted: 11/21/05 version: 3.5 revision: 0
This revision was not posted, but reflects changes made through version 3.4 revision 10 that were removed from the "stable" branch of the distribution.
- Changed the crash backup file name to include the process ID. This is intended to prevent xcircuit process from treating a backup file from another existing xcircuit process as a crash file to be recovered, but the code is not yet finished.
- Enabled creation of parameters on a top-level page, and revised the Tcl "param set" command to handle this case.
- Added a "page links sheet" option to allow querying "sheet A of B".
- Added a "page links load" option to allow symbols to specify which file contains the schematic, and load these prior to writing a netlist.

2008-07-18 20:23 tim Added Wim Vereecken's patch to correctly update the reference counter for graphics images (fixed in version 3.6 but not previously corrected in 3.4).
Also: Updated Wim Vereecken's matgen.tcl from version 0.5 to 0.7.- posted: May 23, 2008 at 2:40am version: 3.4 revision: 29
2008-05-22 17:18 tim Corrected the "-exact" problem in tkcon.tcl, as reported by Denis Dupeyron (it was fixed in 3.6, but not in the stable version as it should have been).- posted: March 10, 2008 at 2:40am version: 3.4 revision: 28
2008-03-09 08:29 tim Removed call to "TclSetBadOctal" that is not an exported routine and apparently is missing from more recent versions of the Tcl code.- posted: September 15, 2007 at 2:40am version: 3.4 revision: 27
2007-09-14 14:18 tim Implemented Wim Vereecken's Matlab import function. This module allows XCircuit to read .ps and .eps files generated by Matlab.- posted: June 14, 2006 at 2:40am version: 3.4 revision: 26
2006-06-14 01:15 eric Fixed multiple dist targets problem

2006-06-09 10:54 eric Fixed "make distclean" to properly clean-up after "make dist"- posted: May 31, 2006 at 2:40am version: 3.4 revision: 24
2006-05-30 11:55 tim Changed the Makefile to properly define "make clean" and "make distclean"- posted: May 25, 2006 at 2:40am version: 3.4 revision: 23
2006-05-24 12:52 eric Added a new dist target to the makefile for building .tgz files
Also: Added a spec file for building RPMs- posted: May 15, 2006 at 2:40am version: 3.4 revision: 22
Initial revision
Also: stable distribution
Also: Changed the wrapper script so that the "Tcl Console" menu button does not appear when xcircuit is invoked with the "-noconsole" option.
Also: Minor corrections to the position of the "+" and "-" symbols to make the placement up-down symmetric with respect to the character centerlines. Corrections made to symbols "opamp", "samp", "wramp", and "vsource".- posted: 3/20/06 version: 3.4 revision: 21
Some changes to the configure script for OpenBSD support without patches.- posted: 3/14/06 version: 3.4 revision: 20
Corrected an error which prevented edited library object names from being applied to the object name. This resulted in confusion, because the library would show the modified name, while the object itself retained its original name.- posted: 3/14/06 version: 3.4 revision: 19
One more minor correction to fix the non-Tcl, non-Win32 compile, which was temporarily broken by the Win32 code.- posted: 3/10/06 version: 3.4 revision: 18
A few minor corrections to the Win32 code: proper handling of "Makefile.win32", and proper definition for line endcap types.- posted: 3/7/06 version: 3.4 revision: 17
Incorporated Michael Goffioul's Windows native graphics support into the source distribution.
Also: Fixed a warning message on number of parts that should apply only to library objects, not pages.- posted: 2/24/06 version: 3.4 revision: 16
Changed the meaning of CAD_HOME to point to "libdir", such that distributions can set it to something like /usr/share without causing trouble. Changed CAD_HOME to CAD_ROOT to maintain backwards compatibility.- posted: 2/23/06 version: 3.4 revision: 15
Changed code to prevent a spurious "Error: end of file" message. Also: Corrected the configure.in once again because Tcl/Tk defines TCL_INCLUDE_SPEC but *not*, stupidly enough, TK_INCLUDE_SPEC.- posted: 2/21/06 version: 3.4 revision: 14
Added the Shift-Button-1 bindings to duplicate Button-2 functions as an alternative to using "xcircuit -2".
Also: Added a flag to line styles representing a "square end cap" to a stroke.- posted: 2/20/06 version: 3.4 revision: 13
Made a couple of changes to the configure script to check some extra locations for the Tk header files which seem to have become standard on RedHat.- posted: 2/13/06 version: 3.4 revision: 12
Corrected an error that can cause xcircuit to crash when a box is drawn.- posted: 1/8/06 version: 3.4 revision: 11
Corrected an error in which the quick screen intersection check fails to include pin and info labels in the bounding box, and so when only pin and info labels intersect the screen area, nothing is drawn.- posted: 11/16/05 version: 3.4 revision: 10
Removed the problem with automatic generation of pin labels on a symbol during a copy action in the schematic.
Also: Added doubly-protected backups to standard file writes. This renames the existing file to filename + tilde ("~") so that the file is not truncated if a crash happens during a normal file write.
Also: Added patch files by Zvezdan Petkovic for proper compilation on OpenBSD.- posted: 11/14/05 version: 3.4 revision: 9
Applied (partially) a patch from Larry Doolittle that fixes a pointer bug in the non-Tcl version, and allows compilation of the non-Tcl version on a 64-bit system.
Also: Fixed the event mechanism to allow pages to be selected in the page directory (otherwise, pages cannot be swapped).
Also: Fixed the Tcl "push" command so that "push selected" now works, and clicking the "push" toolbar button when an object is selected has the expected effect. Also: Fixed the Tcl "label justify" command so that changing vertical justification does not reset the horizontal justfication.
Also: Fixed the Tcl-to-xcircuit string conversion so that plain text with spaces is handled as expected (thanks to Mark Martin for pointing out this problem).- posted: 11/10/05 version: 3.4 revision: 8
Changed an instance of "regsub" to make it backwardly compatible to Tcl version 8.3; otherwise, xcircuit fails to start up properly when linked to Tcl/Tk 8.3.- posted: 10/28/05 version: 3.4 revision: 7
Corrected event handling of schematic/symbol association, which was allowing xcircuit to return to "normal" mode while on a library page, resulting in bizarre behavior, and preventing the schematic/symbol association from being made. Thanks to James Vernon for pointing out the problem.- posted: 10/25/05 version: 3.4 revision: 6
Fixed bounding-box calculations on instance loads so that instanced values of expression parameters are handled correctly on file read-in. Also, corrected "resolveparams" to remove cached expression results before writing a page to a file.
Also: Added component unnumbering feature (as written, only for devices having the "idx" parameter).- posted: 10/21/05 version: 3.4 revision: 5
Added command option "label replace", menu items "Text-> Increment" and "Text->Decrement", and key bindings "i" and "I" (respectively) to auto-increment (decrement) numerical values inside text labels. As part of this, I also rewrote and completed the Tcl list-to-XCircuit string conversion routine.
Also: Fixed a bug reported by James Vernon due to accessing free'd memory, which appears to be fatal under Cygwin but not under Linux.- posted: 10/19/05 version: 3.4 revision: 4
Added command option "library filename" and the ability to save the first file from which a library page was loaded.
Also: Added the "page load -replace" and the ability to load/save specific libraries by name. Changed the "File" menu and the popup prompts to allow all of this to be done from the GUI interface.
Also: Added more Cygwin handling to the Makefile process, and tested the Cygwin compile and install.- posted: 10/6/05 version: 3.4 revision: 3
Some fixes to things broken between versions 3.3 and 3.4: Move "undo" stays on grid. Items being moved during move and copy commands stay with the cursor through pans. Button-3 now does the proper thing for cancellations during move mode.- posted: 10/6/05 version: 3.4 revision: 2
Refined and expanded the hierarchical element handle notation to cover all commands accepting element handles. This will now work for commands such as "element type". Still, only "polygon points", "spline points", and "instance center" commands translate point positions back to the top level.- posted: 10/05/05 version: 3.4 revision: 1
Fixed an error with finishing path edit operations, added "internal units" type to the grid display types, and implemented a (preliminary) hierarchical specification for element handles that can be used with the "polygon points" command to refer point positions back to the top level.- posted: 10/03/05 version: 3.4 revision: 0
Substantially revised the interface and input mechanism, removing the remaining methods that were hard-coded to various mouse buttons. Instead, I have implemented the button "Hold" mechanism in a general-purpose manner that also allows definitions of key hold bindings. I removed many of the event modes, including all of the element creation modes available from the GUI tool buttons, as these are more obviously implemented by changing button bindings. This allows the various modes to be switched on and off, and allows wire drawing mode to be just one of the modes rather than the default mode. Adding "wire", "move", and "pan" modes as more-or-less obvious button binding variations. Added ASCII85 and Flate encoding/ decoding to the graphic read/write operations. Added a "-2" option to the command-line invocation of xcircuit to set mouse button bindings for 2-button mice.
- posted: 9/28/05 version: 3.3 revision: 38
Corrected multiple-button checking routine to look at the event state only, not the button, as the button entry is changed by some routines. This was preventing the shift-button key bindings from working.- posted: 9/20/05 version: 3.3 revision: 37
Corrected SPICE output to generate a line break and continuation "+" character for wraparound lines.- posted: 9/16/05 version: 3.3 revision: 36
Fixed an error with netlist output in which parameters are not substituted if xcircuit is run in batch mode.- posted: 9/15/05 version: 3.3 revision: 35
Fixed parameter indirection---parameter string was not initialized on library read-in, causing a segfault. Also, changed the behavior of ordered spice lines so that they will be placed after any subcircuits are written, to avoid nesting subcircuits. A syntax "spice@" has been added for lines that really should go in front of everything (except for the special title line #1).- posted: 9/14/05 version: 3.3 revision: 34
Implemented "label latex" in the Tcl version, which was missed in the move from Xt to Tcl, and because it is an obscure function, was not noticed for some time. Thanks to Eric West for bringing it to my attention.
Also: Applied a patch by Joerg Wunsch that prevents a segfault when rotating a path element.- posted: 9/08/05 version: 3.3 revision: 33
Corrected an error in netlisting that would incorrectly identify empty parameter strings as the "idx" parameter. Also, added a "-nowindow" switch to the UNIX command-line invocation to allow xcircuit to be used as a filter (batch process) without creating/displaying an X11 window.- posted: 9/06/05 version: 3.3 revision: 32
Changed the handling of netlist writing from symbols, in particular to avoid crashing on encountering unexpected info label contents.
Also: Added a "-replace" option to file loads, that causes any object in a file to be overridden by one in a library "master copy".
Also: Revised the "library make" command to allow an arbitrary number of empty libraries to be created.- posted: 8/10/05 version: 3.3 revision: 31
Fixed a problem with the graphic image handling in which graphic images are saved to the output file if they exist, regardless of whether or not they show up in the output page. Also fixed the PPM reader to handle whitespace and newlines in the header correctly, according to the PPM spec.
Also: Added revision information to the "welcome" message in addition to the major.minor version.
Also: Some changes to the Makefile to properly handle passing of linker flags in the shared vs. static compiles.- posted: 7/28/05 version: 3.3 revision: 30
Fixed a problem with the startup TCL code that causes XCircuit to fail to start if a parse error is found in the user's ~/.Xdefaults file (even a completely unrelated parse error). Thanks to Roland Roberts for the bug report (and, much earlier, Romano Giannetti, although at the time I administered to the symptoms, not the disease.- posted: 7/22/05 version: 3.3 revision: 29
And yet more auto-numbering revisions. Ensure clearing of device indices prior to both netlist output and auto-numbering. Also, fixed parseinfo() to correctly handle the mode="" case.- posted: 7/21/05 version: 3.3 revision: 28
More fixes to auto-numbering code ($#!@&). Appears to work now for various cases, although I am not satisfied that it covers all situations. One part of the fix forces xcircuit to ignore all fixed component assignments when generating flattened netlists. While this ensures that all component numbers are unique, the output is not what might be expected, especially if there is no hierarchy in the schematic. Probably the parsing for fixed device numbers should *not* be done by parseinfo() but should be handled separately, under the assumption that this handles a limited number of backwardly-compatible cases and that normally it should expect to find "idx" and "class" parameters for each component.- posted: 7/20/05 version: 3.3 revision: 27
Revamped the auto-numbering code (again!) to better handle the "class" and "idx" parameter method, and make auto-numbering independent of the netlist format (i.e., SPICE vs. pcb). Device (component) name ("class") was moved from the object structure to the Calllist structure (after all, if the class is parameterized, then an instance may have a different class from the object's default class), and this is generated directly after generating the Calllist structure, since it is independent of the netlist output format.- posted: 7/19/05 version: 3.3 revision: 26
Further corrections to revision 20 code. Device classes are now checked and updated for non-pcb devices (e.g., mosfets) when doing autonumbering.
Also: parameter setting works for multiple selections; e.g., several transistors can be selected at once and have width or length changed simultaneously for all of them. Thanks to Carsten Thomas for the bug report and feature request.- posted: 7/18/05 version: 3.3 revision: 25
Finally logged into SourceForge and incorporated some of the more recent patches found there. Includes a patch to configure.in by Min Sik Kim, and a patch to fontfile.c by Zunda.- posted: 7/17/05 version: 3.3 revision: 24
Updated keybindings with the new function "Graphic", which otherwise causes the help utility to crash. Thanks to John Rigg for the bug report.- posted: 7/15/05 version: 3.3 revision: 23
Added file load and save methods for the "graphic" element, as well as undo/redo operations, a menu item for loading graphic elements, and all essential operations.- posted: 7/14/05 version: 3.3 revision: 22
Corrected broken file parsing from revision 21. Image data is now read from "objectread" like everything else inside the Setup block.- posted: 7/13/05 version: 3.3 revision: 21
Fixed a bug introduced in revision 20. Also, started adding the new basic element type "graphic", to handle inclusion and placement of arbitrary graphic images. This will eventually replace the buggy and cumbersome "background postscript" rendering via ghostscript.- posted: 7/08/05 version: 3.3 revision: 20
Changed the component auto-numbering so that all component values are treated as base-36, to allow handling of non-numeric component numbers. Also, the routine that determines the number to assign will return the smallest unused integer instead of (1 + (largest number found)) so that use of non-numeric values doesn't cause the auto-numbering algorithm to generate strangely large numbers.
Also: The auto-numbering algorithm now looks at the parameter "idx" if it cannot find a "pcb"-style info-label. This allows non-pcb parts like transistors in VLSI schematics to be auto-numbered. This is really the preferred way to handle auto-numbering, and all library parts ought to be updated to contain the "idx" parameter.- posted: 6/28/05 version: 3.3 revision: 19
Resolved the issue with retaining the stack order of parts through a delete-undo cycle, so that all previous undo records point to the correct parts in the correct order. This eliminates a lot of spurious error messages coming from the undo mechanism.
Also: Resolved the issue with polygon/arc/spline/path rotations, where rotations cannot be undone exactly due to accumulating roundoff errors. The solution is simply to treat the rotation as an edit for these element types.
Also: Fixed an error with label deletion. Labels that are edited out of existance were not handled properly, an egregious error that was somehow overlooked.
Also: Modified console.tcl script to withdraw the console window on a window manager "close" request, rather than exit the application. This bolsters the end-user illusion that the console is a subsidiary window of the layout, rather than vice versa.- posted: 6/16/05 version: 3.3 revision: 18
Fixed an error reported by Benoit Bidoggia, in which an attempt to clean up redundant font changes triggers a crash becuase it has been passed the top-level instance instead of NULL (NULL is necessary because this function is called when reading an object definition, at which point there are no instances).- posted: 6/12/05 version: 3.3 revision: 17
Fixed another error that showed up in Uwe's schematic, which is that the "test_insideness" algorithm fails if the box is degenerate---which happens for labels that are parameters set to a null string.- posted: 6/10/05 version: 3.3 revision: 16
Corrected an error found by Uwe Zimmermann in which xcircuit calls free() on an unallocated space when destroying an object containing an indirect parameter.
Also: Added some experimental code replacing the drawing functions with OpenGL. This can be compiled in by passing "--with-opengl" to the "configure" script. However, the code is currently unfinished.- posted: 5/31/05 version: 3.3 revision: 15
Added another feature to the change of revision 14: Info labels that have negative sequence numbers (e.g., "spice-1:", "spice-2:", etc.) will be written after all subcircuit and component output, whereas the usual positive sequenced labels "spice1:", "spice2:", etc., will be written before subcircuit and component output. Each sequenced line is followed by a return character in the output. First and last line of the netlist output is hard-coded (e.g., circuit title and ".end" line in SPICE (see rev 5 comments)).- posted: 5/27/05 version: 3.3 revision: 14
Changed behavior of netlist generation to allow (finally!) info labels on a top-level schematic. These labels are written verbatim into the output. Probably needs checks to avoid attempting to process certain embedded escapes like pins. . .- posted: 4/08/05 version: 3.3 revision: 13
Fixed an error that missed recalulating the instance bounding box after a text rejustification.- posted: 3/29/05 version: 3.3 revision: 12
Changed behavior of the netlist connectivity highlight function in response to a suggestion by Long Yang that pin connection points should be hightlighted, the better to show places where a net does not attach to a pin.
Also: Added a feature in response to a comment by John Barry that error messages disappear when netlists are saved if the netlist is not recreated. This feature includes a checkbox in the Tcl wrapper that by default forces regeneration of the netlist on each netlist file write function.IN PROGRESS---Added "idx" to Pagedata; need to separate areastruct.page from the actual printed page number. This simplifies page re-ordering and allows schematic libraries to be "hidden" among the rest of the pages. xobjs.pages and areastruct.page will still refer to the index into pagelist.

Fixed an error, pointed out by Long Yang and Svenn Bjerkem in which xcircuit crashes when descending into an object. This was due to out-of-bounds array addressing, and must have been in the code for some time, but only shows up on some compilers (Solaris?).- posted: 2/27/05 version: 3.3 revision: 10
Fixed an error in the flattened netlist output that has probably existed in most revisions of 3.3 to date, where net names are not correctly passed down from parent cell to child cell. Thanks to Mark Chang for pointing out the error.
Also: Fixed a bug in the selection mechanism where the selection is not NULLed prior to return from the calling routine if no selections are found.- posted: 2/05/05 version: 3.3 revision: 9
More changes to the selection mechanism. Selection mechanism sorts polygons (wires) according to distance of the nearest edit point. Previous selection is always kept and compared against current selection. "pick" is only advanced if the selections are the same. Pointer position when selecting a polygon to edit is restored from the warped position after a button-3 cancel function.
Also: Added all edit functions to the "undo" mechanism, as well as label creation.- posted: 2/04/05 version: 3.3 revision: 8
Corrected several mistakes in the selection mechanism that left pending (unfinished) events on the stack.
Also: Corrected a problem from rev. 7 that did not register unselection events (key "x") with the undo mechanism.- posted: 2/01/05 version: 3.3 revision: 7
Revamped the selection mechanism (finally) to get rid of the cumbersome "click to select or reject" method. The new method picks one element, and cycles through objects so that a different object is selected on each button press, if several elements are found at the pointer position. This method would be equally unwieldy save for a change in the way object instances are selected---the selection routine recursively searches for elements inside objects that are close to the pointer position (albeit with a wider capture range than on the top level). This prevents selecting an object instance with lots of white space if the pointer is in the middle of the white space (such as a frame or border object).
Also: Corrected the "Make Matching Symbol" callback. Thanks to Mark Chang for pointing out the error.- posted: 1/04/05 version: 3.3 revision: 6
Made additions to the "pcbout.tcl" script to support SMD integrated circuits, and resistors and capacitors (both chip and axial). "pkg" parameter added to the Resistor and Capacitor parts in the "analoglib2" library.- posted: 12/16/05 version: 3.3 revision: 5
Corrected a fatal error in library copies if no valid object is selected. Corrected a compile error (C++-like syntax fails on many compilers). Added option to print or not to print the ".end" statement at the end of a SPICE deck.- posted: 12/10/04 version: 3.3 revision: 4
Corrected an error that allows "temp label" pins to be assigned the same name for different nets. The number following "int" or "ext" on temp labels is now changed to match the net number when referencing the label name, if it is found to be different.
Also: Corrected another bug that causes a crash when copying an edited parameter back to an object. The data record for the PARAM_END structure was not zeroed. This was okay previously because the data record was unused.- posted: 12/06/04 version: 3.3 revision: 3
Corrected a problem in which drawn subcircuits and subcircuits declared with an "X.." in the info label will share index numbers, by forcing SPICE output to generate a devname of "X" for each drawn subcircuit object.
Also: Changed the behavior so that device numbering starts at zero, not one. Otherwise, if a device is numbered zero on the drawing (e.g., by having the index number entered by hand), xcircuit will generate a spurious "duplicate part" warning.- posted: 12/03/04 version: 3.3 revision: 2
Fixed an error (apparently from 3.3 rev 0) that caused parameters to become hosed if changed (also causes program crashes).
Also: Added handling of X11 button4 and button5 events for (potential) binding to mouse scroll wheel motion.- posted: 10/08/04 version: 3.3 revision: 1
Changed the behavior of the PCB netlist generator to be more intelligent about finding the bottom of the layout hierarchy. Also, corrected the netlist generator where it allowed a global net to be merged into a local net.- posted: 9/28/04 version: 3.3 revision: 0
Replaced the "hspice" directory with Conrad Ziesler's "spiceparser". The use of routine AddNTermModule() has broken the spice input for now, although once fixed, the results should be much improved.
Also, changed the handling of expression parameters so that expression parameter results may be numeric, and evaluated results are saved in the PostScript output as instance values. When traversing the hierarchy during redisplay, commands invoking a "selected" element will pick up the object instance being rendered. The combination of these changes allows the implementation of several useful features such as counter-rotation and displaying the name of an object within the object.

Quick fix to allow the non-Tcl code to compile; the experimental "ngspice" code contains numerous Tcl references, and although it does not depend on Tcl in principle, it is easier just to disable the code for the non-Tcl compile. It will not be missed.
Also: Changed the startup method from the hacked-up redirection of $HOME to a standalone "wish"-like executable that sets up "wish" to read in the .xcircuitrc file as its startup script.- posted: 9/07/04 version: 3.2 revision: 26
Changes based on comments from Dale Grover for correct compilation/linking/installing under "Fink" on Mac OS-X 10.3.- posted: 9/06/04 version: 3.2 revision: 25
Fixed the wrapper code to ignore Tk's standard binding for the Tab and Shift-Tab key events during label text input. Otherwise, the window loses focus, which is an annoyance.- posted: 8/25/04 version: 3.2 revision: 24
One major fix to the netlist code to insist that "updatenets" is never run on a symbol. Otherwise, a circuit that has a symbol that is not used anywhere will generate an error when netlisting, resulting in no netlist.
Also, many minor fixes/enhancements to the TCL command-line functions, mainly to support scripting. There is now a script called "sue_xc.tcl" that supports the generation of schematics from ".sue" files (in particular, this is to allow xcircuit support for the IIT standard cell library; see http://www.ece.iit.edu/~vlsi/scells/).- posted: 8/18/04 version: 3.2 revision: 23
Rather important fix from back in revision 19, in which routine "pointtonet" is supposed to merge crossing wires if they cross on top of a subcell port. This is the method used to connect crossing wires with the "dot" symbol, so it is rather important.- posted: 6/21/04 version: 3.2 revision: 22
Added capability to the parameter selection mechanism to handle Tcl-expression parameters of the form "lindex {list}". Such expressions will generate a listbox-type popup window in which the user is prompted to select one of the choices in the list. The parameter will be replaced by the same expression but with changed to reflect the index position of the chosen parameter value. The way to make such parameters in the first place is "parameter make expression {lindex {list} }". To change the expression itself instead of selecting a choice from the list, use "parameter set" instead of the GUI interface. Thanks to Paul Surgeon for suggesting this method. - posted: 5/28/04 version: 3.2 revision: 21
More quick fixes: Makefile error installing .tcl and .lps files due to an error in Makefile.am; library object import now checks library version and does not attempt to import libraries that may be missing a dependency list. Distribution libraries updated to make sure all of them will work with the library import function. Tcl function "library" changed to accept " " when library name is "Library: ". This makes more sense, as it allows one to do, for instance:
"library load asg_spice"
"library asg_spice save asg_spice_new"
- posted: 5/26/04 version: 3.2 revision: 20
Quick fix to a bug pointed out by Petter Larsson, which must have been in the code for some time, which checks for names incompatible with the PostScript interpreter but then fails to make the change. Also, cleaned out some source code copies left over from bus representation implementation.- posted: 5/20/04 version: 3.2 revision: 19
Finally got the bus notation handling into enough of a working condition that I dare to post the distribution. In addition to basic fixes, improvements include handling of buses and partial buses with the "connectivity" function, and in particular, handling of instance-specific labels throughout the netlist (previously was only applicable to the netlist output). The instance-specific labels allow the new "tap" object to work. Added the tutorial file "buses.ps" to the examples directory.- posted: 5/06/04 version: 3.2 revision: 18
Removed the requirement that the GUI must be in place prior to startup. XCircuit can be embedded directly in another application with or without its own GUI. Without the GUI, it is necessary to create (and map) a "simple" window (e.g., "simple .mytest.draw -bg white -width 700 -height 400"), and then set the Tcl array variable "XCOps(window)" to be the Tk pathname of this window. This creates a window into which things can be drawn by Tcl command-line commands. To enable button and key actions, it is necessary to do:
bind .mywin.drawfrom the Tcl command line. It is also possible to rewrite the wrapper script so that the whole GUI is present but rooted in a location different from ".xcircuit". In that case, set the variable "XCOps(top)" to the top-level window name before invoking xcircuit::start. In either case, one must run "wish" first, then load "xcircuit.so", create the appropriate Tk window or windows, set the appropriate XCOps() variable, then do xcircuit::start.{xcircuit::standardaction %b down %s}
bind .mywin.draw{xcircuit::standardaction %b up %s}
bind .mywin.draw{xcircuit::standardaction %k key %s}
bind .mywin.draw{focus %W} Handling of bus notation is still unfinished in this (unreleased) version, and probably breaks the schematic capture altogether. This will be fixed prior to an actual distribution release.
- posted: 4/14/04 version: 3.2 revision: 17
Major enhancement: Handling of bus notation in netlists! Also, Prohibit parameters from shadowing PostScript reserved names and definitions in xcircps2.pro, as is done for object names. Also, finally found and excised the bug that was preventing correct comparison between object definitions on read-in, which was introduced along with the parameter type- promotion code. Fixed another bug which prevented parameterizing position. And, fixed a bug which prevented disabling flip invariance on text from the menu in the TCL version.
Also: made more convenient constructor/destructor functions in elements.c, for general purpose use; these are called from tclxcircuit.c.
Also: Reimplemented "strdup" as "Tcl_Strdup" in the TCL version; otherwise, there are places where memory is allocated by strdup, bypassing TCL's memory allocation, but free'd by Tcl_Free().
Also: modified the library manager "library import" routine to load any library instances of an object in addition to the object itself.- posted: 3/15/04 version: 3.2 revision: 15
Reinstated colors and other parameters as XDefaults-style options in the TCL version using the Tk_GetOption() command. Changed autoconf so that the TCL version is compiled by default (unless not found, or explicitly disabled). Initial work on bus notation parsing.- posted: 3/03/04 version: 3.2 revision: 14
Added a library manager (often requested) for handling large lists of parts. Allows objects to be imported from libraries piecemeal.- posted: 3/03/04 version: 3.2 revision: 13
Changed the TCL scripts and shell startup file so that the README directions for a test execution prior to install actually work as advertised. Also, finally found a way to force automake to compile the tcl version with just "make" and "make install", thus hopefully eliminating the greatest source of compile-time woes. Re-implemented the .so file loading so that the reported error is the real root cause error, not "file not found".
Also: removed Imakefile and all references to it.
Also: Added a menu item for the PCB layout generation. This is not yet sourced by default.- posted: 3/01/04 version: 3.2 revision: 12
A couple of fixes to bugs reported by Brek Miller. 1) Library copy did not copy parameters correctly (missed both the "key" and "which" entries), and 2) The object comparison mechanism failed to correctly compare objects with parameters due to a typo in the code.- posted: 2/27/04 version: 3.2 revision: 11
Some changes to command functions and netlist output. Added file lib/tcl/pcbout.tcl, a script that converts an xcircuit schematic into a preliminary PCB layout. This is very spare at the moment, to say the least; for instance, it only supports 7400-series devices. But it's mostly proof-of- concept.- posted: 2/26/04 version: 3.2 revision: 10
Some Makefile/configure changes, esp. for systems like Debian that do not find the Tcl/Tk include files. Also, rearranged the menus so that "linewidth" commands (global and wire line- width) are more obviously placed ("wire linewidth" duplicates the "element border" entry). Thanks to Forrest Cook for this suggestion. Also, rewrote the library load command in xcircuit.tcl so that it prints the actual root cause error instead of complaining about "file not found". Also, rewrote and extended the "help" window in Tcl, making it entirely script-driven from Tcl, and adding help text for each function. This required adding Tcl command "bindkey" variant with no arguments, which returns a list of all functions which can be bound, and "bindkey -func", which definitively asserts that the argument is a function, not a key (because, e.g., "Delete" is both a key name and a function). Also, made XCF_Prompt (key "%") execute xcircuit::raiseconsole in the TCL version (previously undefined in TCL). - posted: 2/20/04 version: 3.2 revision: 9
Greatly expanded the undo mechanism, which now covers most of the major xcircuit functions. This is definitely "beta test" code. Also, renamed a number of functions and definitions to be clear about the difference between an element and an object (this confusion was left over from the really early days of the program).- posted: 2/11/04 version: 3.2 revision: 8
Improved the ghostscript rendering mechanism so that it can handle (non-encapsulated) pages output from ghostview (which includes some global state-setting commands). Also, greatly improved the rendering by backgrounding the process. Xcircuit draws a blank background and continues until ghostscript reports that the page is finished, at which point the page gets redrawn with the background.- posted: 2/06/04 version: 3.2 revision: 7
Some fixes to the ASG and hspice routines; automake now checks for g++-3vs. the older header file and adjusts accordingly. The hspice parser no longer produces files netlist.sp and netlist-flat.sp. Compilation of ASG is now disabled by default (and will be until it's stable. . .), and requires "configure --enable-asg" to enable the module. - posted: 2/05/04 version: 3.2 revision: 6
Added the ASG and hspice parser modules back in, with additions to the master Makefile and configure script to support compiling both modules into the xcircuit Tcl shared object library xcircuit.so.- posted: 1/29/04 version: 3.2 revision: 5
There was a 3.2 previously for the ASG implementation. This is being done again from scratch, but I'm continuing the revision numbers where I left off, at 5. Prior to adding ASG back in, version 3.2 is in the process of implementing the "comprehensive undo" function by creating the framework for running undo/redo events and recasting the "delete" function into this framework. More to be added in coming revisions.
- posted: 1/28/04 version: 3.1 revision: 38
Removed #ifdef SCHEMA from everything. This should have been done long ago. . . Also, removed %%PageBoundingBox from the output for encapsulated PostScript files, as this appears to screw up output when including the drawing in a document, such as a LaTeX file. Changed the behavior of the output dialog box such that the page label is checked before writing, and the page label is set to the filename if the label is still "Page #" at the time the label is set. Fixed the behavior of selecting fill and border styles, especially a critical error with fill styles that would allow polygons to acquire an invalid state, causing netlist problems and/or unmatching PostScript output. Changed the selection behavior such that elements are not unselected after border/fill/color changes. Fixed the behavior of network connectivity highlighting to work with multi-page schematics. Changed some event handling to let most button- release events act on the mouse position on the previous button press (this works for drawing wires and editing polygons, but not for copying elements). Added "%N" escape to the tag callback mechanism to allow all arguments to be passed to the callback procedure as a list. Fixed marking of "Closed" checkbox in the Tcl "Border" menu.- posted: 1/23/04 version: 3.1 revision: 37
Preparing for XCircuit 3.2 (ASG). Revised some of the code structure of netlist.c, added routines NameToPosition(), from the ASG code (xcircuit-3.2), and PortToPosition(), which is a variant thereof. Added the routine ratsnest(), called by the command "netlist ratsnest" in the Tcl console, which demonstrates some of the features required for true ASG.
Also: removes deleted items from the netlist piecemeal, so that an ASG system can operate on an invalidated netlist without encountering dereferenced pointers, or elements which are not on the page they claim to be on.
Also: Fixed another bug similar to that in #271 where no space was printed after the closing "}" in multipart strings appearing in parameters, which equally bad results.- posted: 1/21/04 version: 3.1 revision: 36
Added support for schematics spread over multiple pages. The method is that all top-level pages that have the same page label (object name) will be considered part of the same schematic. One of the pages is considered the "master", or "primary" page, and keeps the netlist/portlist/calllist for all the pages. The other pages are the "slave" or "secondary" pages, and refer to the master page for netlist information.
Also: Fixed a couple of bugs resulting from messing with the parameter formats, namely 1) put back the check for equal "which" value in varpcheck and varfcheck, and 2) added a space after printing a null-string "()" parameter value.- posted: 1/16/04 version: 3.1 revision: 35
Modified and completed support for expressions in parameters. In the TCL version, this supports all TCL expressions. In the non-TCL version, it allows simple character strings to be used in parameters. The expressions are not translated into PostScript; the PostScript output records the expression, which is unused, and the last evaluated result, which is taken to be the parameter value. Cleaned up more code for numeric and indirect parameters, and added TCL options "-verbatim" and "-indirect" to the "parameter" command to facilitate handling indirect and expression parameters.- posted: 1/09/04 version: 3.1 revision: 34
Cleaned up and finished most of the stuff having to do with numeric parameters, parameters promoted from numeric to string types, parameters on a top-level page, and indirectly-referenced parameters.
Also: Tcl variables moved into a single array.
Also: Some support for arithmetic expressions in parameters. Very rudimentary at present.- posted: 12/16/03 version: 3.1 revision: 33
Fixed the text justification routine in TCL ("label justify ..."). Thanks to Petter Larsson for the bug report. Fixed two problems with "page clear"---one reported by Brek Miller, showing that the free_single() routine was removing parameters from the referenced object, not the instance, and one reported by Joel Kuusk, where the Tcl "clear page" command allows clearing a page while editing an object instance in the hierarchy of that page, causing an immediate crash. Finally, corrected prototypes.h for routines setjustbit() and setpinjustbit() for the non-Tcl compile, left in an improper state in revision 32. Thanks to Dave Armbruster for this bug report.- posted: 12/10/03 version: 3.1 revision: 32
Fixes to the linewidth/border width changing from the menu in the TCL version, as pointed out by Rob Olsen. Also, on suggestion from Makram Mansour, added LaTeX label handling.- posted: 12/08/03 version: 3.1 revision: 31
Three fixes from bug reports by Bliss Carkhuff: "page save" returns TCL_OK rather than an undefined value, parameter entry requires exact match to keywords to get text escapes such as "underline", and substring parameter creation corrected for creating parameters in the middle of a label. Page save error also pointed out by Mark Martin, and Rob Olsen who additionally noted the additional error in linewidth selection (which has also been fixed).- posted: 12/01/03 version: 3.1 revision: 30
Made another change to the output such that all objects used on all pages are output first, inside a PostScript DSC block "DocumentSetup", followed by all the pages. This modification allows viewers like ghostview to figure out that these objects may be used by any page, and prevents errors that occur when skipping pages forwards or backwards in the viewer.- posted: 11/26/03 version: 3.1 revision: 29
In response to Romano Giannetti, fixed the bounding box routines so that EPS files are handled the way they used to be. The only thing required was to set the overall bounding box to remove the 1" margins; the page bounding boxes remain the same, and ghostscript, ghostview, and EPS insertions into LaTeX documents all appear to be handled correctly. Also, added the "override" commands to the TCL interface, although to match the rest of the TCL syntax, these have been changed to "library override", "loadfont override", etc.- posted: 11/19/03 version: 3.1 revision: 28
Changed the way XCircuit handles embedded bounding boxes and does page scaling and translation in the output. Removed the "offsets" comment line from the output and changed it to a PostScript translation, which means that all the positional values in the PostScript output on a top-level page are all in xcircuit internal units, without offset, and are therefore invariant with scale, page size, etc. When an embedded bounding box is present, xcircuit translates the output such that the bounding box is centered on the page. If "auto-scale" is selected, then the output is scaled such that the bounding box fits centered on the page with 1" margins minimum.- posted: 11/16/03 version: 3.1 revision: 27
Extended the parameter method to include parameters passed inherited by an object instance from its parent. Fixed the "make object" method such that parameters are copied into the new object (as yet, the new object does not correctly inherit the parameter from the parent). Added preliminary support for promoting numerical parameters to strings.- posted: 11/11/03 version: 3.1 revision: 26
More fixes and extensions related to parameter key:value pairs. Added a popup window in the Tcl version for editing substring parameters of an object instance, including functions for formatting ASCII strings from string parameters and vice versa. Added a function for the "Add New Color" button in the Tcl version, which was missing. Command syntax "color" changed to "color set " and option "color add " added. - posted: 11/06/03 version: 3.1 revision: 25
Changed parameter handling to a key:value pair model. Revised built-in libraries to take advantage of this method, using keys like "value", "units", "length", "width", etc. Expanded and revised the "parameter" command in Tcl-based XCircuit to provide the key:value information, as well as providing parameter information down one level in the hierarchy for an object instance (using the key "-forward" as the last argument to the "parameter" command). Added command option "type" to list parameter types, or to list parameters by type. Finished code for removing parameters.- posted: 9/19/03 version: 3.1 revision: 24
Added feature (macro "V" key) to make a library virtual instance from an object selected on a page. This allows users to make temporary copies of parameterized (or rotated, or flipped) objects for quick retrieval. Several corrections: Xcircuit now checks for symbols associated with schematics and saves them, even if the symbols are not used in any schematic. This prevents associations from being lost after a save/quit/load cycle in an unfinished schematic.
Also: Snap and polygon edit will invalidate the netlist.
Also: "Make matching symbol" reports an error if the schematic page has an invalid name.- posted: 9/15/03 version: 3.1 revision: 23
Corrected revision 22, which duplicated the NameToObject routine by mistake. Also added TCL wrapper key bindings for function keys "Page Up" and "Page Down" to increment or decrement the page number (helps with large numbers of schematic pages).- posted: 9/10/03 version: 3.1 revision: 22
Moved routine NameToObject from tclxcircuit.c to schema.c, since it is used by the non-Tcl based code and prevents compiling the non-Tcl version. Thanks to Swee-Ann Teo for pointing out the error.- posted: 9/05/03 version: 3.1 revision: 21
Fixed a problem with the Tcl calls to the zoom functions, which were passing a NULL event structure. Thanks to Ed Casas for pointing out this error.
Also: Fixed the Makefile.am file for compilation under Cygwin, which was presented the wrong name for menudep.o. Thanks to Carlos Davila for pointing out this error.- posted: 9/04/03 version: 3.1 revision: 20
Changed key and button handling in Tcl to work using the Tk "bind" function, with the usual behavior being bound to the "standardaction" command. Standard actions can be rebound using the xcircuit "bindkey" command, or keys can be bound to Tcl procedures using the Tk "bind" command.- posted: 8/12/03 version: 3.1 revision: 19
Required reconfiguring without Tcl once to generate the "Makefile.in" in the Xw directory; otherwise, automake 1.7 becomes a requirement.- posted: 8/06/03 version: 3.1 revision: 18

Incorporated a patch from Max Horn to remove all references to "malloc.h" from the headers, and fix the configuration file for Mac OS-X compilation.- posted: 4/29/03 version: 3.1 revision: 13
Fixed a problem due to automatic search for schematics which prevents a single page from being saved. The output window now shows both "schematics" and "subcircuits" with checkboxes; pushing "schematics" unlinks top-level schematics, and pushing "subcircuits" can prevent subcircuits from being saved along with the file. In either case, the filename is blanked out so the user will not mistakenly overwrite the original file with a truncated one. In conjunction with this method, the Tcl "page links" command has been extended to include the options "independent", "dependent", "total", "pagedependent", and "all". Eventually, I expect to add an additional option "list" to list page names instead of simply enumerating them. Thanks to Mark Jones for pointing out this error.- posted: 4/14/03 version: 3.1 revision: 12

Replaced TkCon with the version used with magic, fixing a minor issue with handling backslash escape sequences.- posted: 2/26/03 version: 3.1 revision: 9
Fixed the install for revision 8, which failed to run the xcircuit.tcl script through the m4 preprocessor. Also, on recommendation of Mark Jones, added a warning message when pins exist on a symbol which do not exist in the associated schematic.- posted: 2/23/03 version: 3.1 revision: 8
Resolved numerous issues with cross-application methods. Overloaded the "label" Tcl procedure to accept both xcircuit and Tcl syntax, and removed the "bgerror.tcl" file. Added procedures for calling netgen, IRSIM, and magic while running XCircuit.- posted: 2/19/03 version: 3.1 revision: 5
Fixed (for the third time(!)) occurrences of "getline" which should have been changed to "setline". Fixed the toolbar widget so that it recomputes its width when the window size changes, and so that it does not squeeze the height of the bottom message bar.- posted: 2/12/03 version: 3.1 revision: 4
Added handling of "va_copy" to the configuration script for systems which do not define it.
Also: Added "%x" and "%y" escapes to the info label syntax, for writing positional information to the output (helps LVS programs like "netgen" trace back errors to the schematic). Split the "Manifest" file into "CHANGES" and "TODO" and started adding revision numbers to the change log entries to match the revision number on the website download page.- posted: 2/10/03 version: 3.1 revision: 3
Added Tcl handling of the string parameter insertion via a popup prompt.- posted: 2/04/03 version: 3.1 revision: 2

Finished preliminary version of Tcl-based xcircuit. Relocated runtime files back to (default) "/usr/local/lib" (instead of autoconf's default $datadir "/usr/local/share"). Threw in tkcon.tcl for compatibility with magic/irsim/netgen and recast fprintf() as macro Fprintf(), which calls "tcl_printf()" in the Tcl version and "fprintf()" in the other versions. Added command-line function "-exec" to the Tcl version for running in batch mode (or alternately, just to bypass the default startup file).
