• posted: September 20, 2020 at 3:00am     version: 3.10     revision: 29
  Applied patch by Kevin Zheng to avoids a crash condition if the XCreateIC() call fails (which is presumably system-dependent, and can return NULL).
  Made a change to the font loading with XLoadQueryFont() to fall back on absolutely anything available (4th attempt). And if that fails, it issues a stern warning about not having any X11 fonts available.

  Corrected a PCB netlisting error where code failed to check for a net count of zero and therefore attempted to access a non- existing pointer.
  
• posted: June 20, 2020 at 3:00am     version: 3.10     revision: 27
  Applying patch from Dan Moore's commit on github to correct for a problem with pointer sizes that needs to be handled in the code for Tcl_GetHandleFromObj().
  
• posted: May 31, 2020 at 3:00am     version: 3.10     revision: 26
  Corrected the SVG output for text characters "<" and ">" to the html encodings "<" and ">", respectively, per the bug report from Henk Boezen.
  
• posted: May 20, 2020 at 3:00am     version: 3.10     revision: 25
  Corrected an error where a label is incorrectly unselected when "Parameterize" has been called from the menu while the label is being created, causing a crash. In the same place in the code, corrected the position of the text cursor to account for the added parameter start and end markers.
  
• posted: April 28, 2020 at 3:00am     version: 3.10     revision: 24
  Added the ability to mark object instances as non-netlistable on a per-instance basis (supplements the ability to mark objects as non- network, which makes all instances automatically non-netlistable). There is no method to make non-network objects netlistable on a per-instance basis, only vice versa.
  
• posted: April 26, 2020 at 3:00am     version: 3.10     revision: 23
  Corrected an error in the PCB netlisting which could cause nets to get scrambled (in particular, regular nets could get merged into global nets such as Vdd and Gnd by accident).
  
• posted: April 25, 2020 at 3:00am     version: 3.10     revision: 22
  Corrected the wrapper, which had not updated the starting index for colors since a new pre-allocated color was added (which was, actually, quite a long time ago). This prevents the "new window" and "close window" options from working properly, as Tcl throws an error when an image for a non-existent color button is referenced.
  
• posted: April 21, 2020 at 3:00am     version: 3.10     revision: 21
  Made another correction to the arc decomposition for path drawing; this one is more fundamental than the last error, which was only in the cairo code. This one failed to add a line to an arc in a path if the arc's start point differed from the previous path point. That led to a difference in behavior between xcircuit and PostScript. Also found that the curve approximation of arcs was not handling conversion to integer properly and so was generating slightly incorrect curve approximations to arcs due to roundoff error. Thanks to Edgar Olthof for pointing out the error and providing detailed examples.

  Corrected one missing void declaration on a routine in Xw (largely deprecated, but still. . . ), and checks for NULL areawin in two places pertaining to batch mode use. Thanks to Kevin Zheng for the patch.
  Corrected an error in the cairo graphics implementation of the path drawing routine, which fails to draw a line to the first point of a curve if the curve first point is not the same as the previous path point.

• posted: January 29, 2020 at 3:00am     version: 3.10     revision: 16
  Added configuration option --with-distdir= to allow installation to a location that is not the final runtime install directory, but also without appending the whole install directory to the end of DESTDIR.
  Corrected --with-distdir= option use of withval in configure.in.
  
• posted: January 28, 2020 at 3:00am     version: 3.10     revision: 15
  Corrected the point-advancing routine (during polygon/path/spline edit) to avoid getting "stuck" when degenerate points are present.
  
• posted: November 23, 2019 at 3:00am     version: 3.10     revision: 14
  Added a patch from Dan Moore to fix a problem with multi-byte UTF characters returned by TclEval() not being displayed correctly in an xcircuit string. This problem shows up in expression parameters where the parameter returns an octal code, e.g., 'return "\260"'.
  
• posted: July 4, 2019 at 3:00am     version: 3.10     revision: 13
  Added a screen resolution check in preparation for handling retinal display resolution.
  Added prototype for getscreenDPI(), and fixed a return without value in tclxcircuit.c.

  Update at Fri Oct 12 11:00:31 EDT 2018 by tim
  Corrected (presumably) an error that causes xcircuit to crash if a non-key event (modifiers only) is passed to the UTF-8 conversion subroutine (or maybe buffer count doesn't include trailing null? Either one is possible and documentation is sketchy).
  
• posted: June 21, 2018 at 3:00am     version: 3.10     revision: 10
  Update at Wed Jun 20 12:24:51 EDT 2018 by tim
  Some experimental code to convert keycodes to keysyms to UTF-8 codes and then lookup the encoding from the UTF-8 encoding tables.

  Update at Mon Apr 23 19:48:14 EDT 2018 by tim
  Applied a patch from Viking-coyote for Gentoo Linux, making use of the $TCL_LIB_FILE variable from tclConfig.sh instead of trying to construct the library file name from parts.
  
• posted: February 10, 2018 at 3:00am     version: 3.10     revision: 8
  Update at Fri Feb 9 12:38:17 EST 2018 by tim
  A number of updates supporting batch mode, for colors and fonts, and for correcting minor issues with startup. Versioning changed to parse the version string instead of treating it superficially as a floating-point number (which it's not).
  Also: Extended method of last commit to include a non-Cairo graphics compile.
  Also: Implemented a hard kill to avoid hanging in a terminal on a Ctrl-C.
  Also: Removed the backup file saving during batch mode, which also removes a crash condition that was happening during backup due to an X11 call.
  Also: Additional change to avoid querying the cursor position when in batch mode.
  
• posted: February 9, 2018 at 3:00am     version: 3.10     revision: 7
  Update at Thu Feb 8 10:15:46 EST 2018 by tim
  Modifed the startup so that the command line will accept any number of space-separated files, instead of the former method, which required a comma-separated list with no spaces, which is incompatible with doing things like 'xcircuit *.ps'.
  Also: The first truly batch version of xcircuit implemented for the command-line options "-nowindow -noconsole". The version does not require a DISPLAY variable or a connection to an X server, and may take commands from stdin and generate graphics, netlists, and so forth from a script without regard to any graphics state.
  
• posted: February 6, 2018 at 3:00am     version: 3.10     revision: 6
  Update at Mon Feb 5 15:13:17 EST 2018 by tim
  Corrected an error in "unparameterize" that failed to remove a parameter from a string if that parameter has no instance value. This would lead to an immediate crash. Also noted that the routine removes only the first parameter in the string, so modified it to remove all parameters in the string. This is correct behavior if the whole string is selected. However, it needs a different method for interactive edit mode, to remove only the parameter under the cursor (not yet done).
  Also: Added code to implement a different "Unparameterize" method when editing a label. Only the parameter where the cursor is located will be removed.

  Testing standard git functions (instead of the existing scripts)
  Also: Merge branch 'master' into work
  Also: Added special handling for the "bbox" line that appears in .lps files that are font vector files. This allows a font vector file to be more easily edited within xcircuit, and will preserve the bounding box as understood by the vector font code.
  Also: Update at Mon Sep 25 21:41:45 EDT 2017 by tim
  Also: Merge branch 'master' into work

XCircuit Version 3.9

• posted: April 24, 2018 at 3:00am     version: 3.9     revision: 73
  Update at Mon Apr 23 19:48:54 EDT 2018 by tim

  Update at Mon Feb 5 15:14:30 EST 2018 by tim
  Same correction as made to xcircuit-3.10: Corrected problem that causes a segfault if "unparameterize" is used on a label containing a parameter that takes the default value.
  Also: Added code to implement a different "Unparameterize" method when editing a label. Only the parameter where the cursor is located will be removed. Same change as made to version 3.10.
  
• posted: January 24, 2018 at 8:42am     version: 3.9     revision: 71
  Changed behavior to avoid having a blank entry for "Filename" in the output properties window. However, it is currently popping the window down even when it notes illegal characters (such as whitespace) in the filename, so that the impression is that the file has been saved successfully, not that there has been an error.
  Also: Update at Sat Dec 9 13:13:36 EST 2017 by tim
  Also: Merge branch 'master' into work
  Also: Fixed mousehints, which was not compatible with multiple windows.

  Corrected the XCF_Exit binding callback "quitcheck" such that if there are no changes and no prompt is required, the Tcl registered command "quitnocheck" is called at the end, so that xcircuit does not keep running after preparing for exit.
  
• posted: July 22, 2017 at 3:00am     version: 3.9     revision: 67
  Corrected an error in edit point cycles that could cause a crash under a fairly specific set of motions, rare in practice except when XWarpPointer() does not work (as happens on VNC sessions), in which case it becomes much more common.

  Applied patch from Erik van der Wal to correct an error in has_param().

  Added patch from Erik van der Wal to fix parts of the non-Tcl xcircuit compile broken by recent font encoding changes, and a few corrections to the menu for text anchoring.
  
• posted: March 29, 2017 at 3:00am     version: 3.9     revision: 64
  Updated text handling code to automatically insert encoding arrays into the output file header for anything that is not Standard or ISOLatin1. This avoids the need for "ogonkify" and works for everything except sending the output PostScript directly to a printer (which is practically deprecated in favor of making a PDF file). Also worked around a minor problem where drawing font glyphs causes the internal count of changes to increment for each glyph, making xcircuit save something like five backup copies every time the font character map is drawn.
  
• posted: March 27, 2017 at 3:00am     version: 3.9     revision: 63
  Implemented Cyrillic (ISO8859-5) encoding for use with the Cairo graphics, although no vector drawn fonts are available (yet). Unlike ISOLatin-2 and ISOLatin-5 implementations, the encoding tables are written directly to the prologue, so no post-processing is needed. However, the same method should be able to be used with the other ISO encodings.
  
• posted: March 13, 2017 at 3:00am     version: 3.9     revision: 62
  Corrected an error with the non-Tcl compile where prototype definitions for defaultscript and loadrcfile are defined for the Tcl/Tk compile.
  
• posted: January 25, 2017 at 3:00am     version: 3.9     revision: 61
  Corrected error in allocation of files included in netlist which generates a crash condition if more than one file is included.
  
• posted: December 5, 2016 at 3:00am     version: 3.9     revision: 60
  Corrected justification under flip invariance, which should not be reversed like anchoring is.
  
• posted: November 14, 2016 at 3:00am     version: 3.9     revision: 59
  Corrected lack of refresh after doing a text auto-increment on an unselected label.

  Also: Merge branch 'work' into tomerge
  
• posted: November 6, 2016 at 3:00am     version: 3.9     revision: 58
  Corrected error in text center justification (the one that has been done properly, not anchoring), which would cause a segfault when used with 1-line text (for which center justification is meaningless, but of course it shouldn't crash the program).
  Also: Update at Sat Nov 5 21:06:24 EDT 2016 by tim
  Also: Merge branch 'work' into tomerge
  
• posted: October 20, 2016 at 3:00am     version: 3.9     revision: 57
  Corrected behavior with respect to netlist symbol blocks that have no pins but connect to a schematic that prints info labels to the netlist.
  Also: Update at Wed Oct 19 11:19:15 EDT 2016 by tim
  Also: Merge branch 'work' into tomerge
  Also: Corrected "Load Dependencies" behavior so that if a link file does not exist but there is a schematic attached to the symbol, then "Load Dependencies" does not report an error.
  Also: Added missing hierarchy stack back into UDrawObject for cairo graphics. Without it, expression evaluation in parameters does not work correctly.

  Finished correcting the parameter delete code. Appears to work correctly now in tests.
  Also: Update at Thu Oct 6 08:56:40 EDT 2016 by tim
  Also: Merge branch 'work' into tomerge
  Also: Fixed behavior where copy of a library object does not realign the page view of the target library, resulting in a blank, off-screen view the first time an object is copied into the user library.
  Also: Modified behavior of parameter window so that listboxes track each other when scrolling.
  Also: Also made the help window listboxes scroll synchronously.
  Also: Modified the startup so that errors in the startup script don't get obliterated but are printed to the output.

  Reworked the dialog widget, which was being over-used, and causing conflicts in places where all properties of one dialog box use were not completely replaced when reconfiguring the dialog box for another purpose. The "save technology" and "make symbol" dialogs were spun off as their own dedicated widgets.
  Also: Update at Wed Oct 5 13:48:12 EDT 2016 by tim
  Also: Merge branch 'work' into tomerge
  Also: Corrected the "parameter delete" function and bound it to key Alt + Delete, making it easier to remove parameters from text strings.
  Also: Implemented parameter delete for cases of parameters that are not strings (integer, float, and expression).
  Also: Finished debugging/correcting parameter delete function.

  It was discovered that "underline" can be set as the last entry in a label, and this will cause the output PostScript to be invalid, causing a stack underflow as the underline procedure expects an argument on the stack, and if it's the last thing in the label, then there are no additional arguments on the stack. Added a stack count to the {ul} and {ol} procedures that cause them to do nothing if encountered at the end of a label.

  Changed all of the rotation values from short integer to type float. This is in preparation for a vector-based interactive rotation method, although a vector position is preferable to a scalar rotation value. Also, added a clip mask to the cairo drawing of a graphic so that the graphic is drawn correctly in rotation (fortunately cairo makes this task trivial).

  Added a new feature to support true text justification (center and right justification). Renamed everything previously called "justification" to "anchoring", since that is what the feature actually implemented. May have interactions with tab stops and margin stops which have not been checked.

  Surprised to find that I had not changed the history filename on the tkcon.tcl script in xcircuit; this makes the history unique to xcircuit so that commands do not get confused with/overwritten by other uses of tkcon.

  Also: Not realizing that I had never updated xcircuit's quit procedure to be compatible with the history file declared in tkcon.tcl, I implemented it at last. History file is now unique to xcircuit and does not get merged with other uses of tkcon.

  Corrected "suspend" from being type "char" to being type "signed char". Because "char" is not specified in the C spec as being either signed or unsigned, it is subject to interpretation by the compiler, and this differs depending on the OS. gcc interprets it as signed. Irix and AIX CC compilers interpret it as unsigned. Thanks to Chris "The Last of the Irixians" Wormuth for debugging this issue.

  Also: Moved some hard-coded resources from the wrapper script, where they don't belong, to the resource script, where they do. Otherwise it becomes more difficult to customize the resources.
  Also: Left a temporary resource used for testing in the resource file.
  Also: Fixed an error with generating new windows caused by having a focus event handled early, which overwrites areawin with the nonexistant new window, making it impossible to copy values from the old window to the new one unless a pointer to the old window is made before calling GUI_init.

  Corrected spice output for the case that a symbol without a subcircuit is instanced (X...) but the symbol contains buses for pins such as "B(7:0)"; the pin bus name must be recast into individual nets to compare to the spice subcircuit call ports. This should work for CDL netlists as well, as a bus in the port list will be compared to a pin that is a bus.

  Also: Update at Sat Dec 6 15:06:39 EST 2014 by tim
  Also: Merge branch 'work' into tomerge
  Also: A few extras for netlisting: (1) Auto-detect bus delimiters in files, and change "buschar" where appropriate, so that issuing "option buschar" is not required, although a warning will be issued. (2) Generate a warning instead of an error when a "dot" is placed over a bus wire. This should be handled automatically without either an error or a warning, but it does not handle the case where a dot is placed over crossing wires. This situation will fail to netlist correctly, making the warning essential.
  Also: Made a simple change that allows "dot" objects to take on the dimension of the bus underneath, so that dots on buses do not need to generate warnings, and are handled correctly when placed over crossing buses (although the buses need to be of the same dimension; otherwise, a tap is required instead of a dot).

  Overhauled the configuration file for two purposes: (1) depend on the values defined in tclConfig.sh and tkConfig.sh, instead of attempting to bypass them (they used to be unreliable, but are believed to be okay in 8.5 and 8.6), and (2) make the Cairo graphics interface enabled by default (since I have been using it for some time now and it is deemed stable). Also, added some output at the end of "configure" to summarize the options chosen, and to alert the user when recommended options were not able to be used, along with useful suggestions.

  Corrected a problem that would allow technology files to be overwritten with a truncated version if some of the objects were imported using the "import selected" function from the library manager, followed by "save technology". The proper method now is to force a new filename to be given to the technology; once that is done, it is easy to import objects from the original technology file and add them to the new one.
  Also: Update at Sat Feb 8 12:31:15 EST 2014 by tim
  Also: Merge branch 'master' into work
  Also: Modified a behavior that has been in place for a long time: When a library object is copied and given a new name by prepending an underscore, the underscore is put in front of the name but *not* in front of the technology prefix, so that the new object remains in the same technology, and no new technology is implied.

This does not address the problem of writing back to the file and having the file overwritten with a new file containing only the loaded object. There needs to be a "merge" routine for the writeback.

  Updated xcircuit with a much-needed object replacement feature. The command "instance object" previously took no arguments and listed the object name of each instance. The new command option is "instance object " and will change the object of the instance. There is a corresponding menu item "Edit->Replace" that brings up a dialog box where a new object name can be entered and applied.

  Also: Created a new command option and UI method for moving objects from one technology to another. The command "technology objects " has been extended to include "technology objects ", which will move all objects in list "" from their existing technology into the technology . The UI version of this is a menu item "Edit->Change Technology" that generates a popup prompt. Selected items in the library will appear in the text box, or the names of objects to move can be typed into the text box. The target technology is selected, and "Okay" precipitates the move. Both the original and new technologies are marked as modified.

  Corrected the handling of technology namespaces so that changing a library object's name from one technology namespace to another will mark both namespaces as modified, causing xcircuit to insist that the user take action to either write the technology file or ignore it when doing either "Write All" or exiting xcircuit.
  Also: Update at Mon Jan 6 11:54:35 EST 2014 by tim
  Also: Merge branch 'master' into work
  Also: Made a correction to the way library pages are composed so that the names of objects are prevented from colliding with one another. This is especially apparent when technology namespaces are included in the name (enabled by Options->Show Library Namespaces).
  Also: One minor semantic change: "Show Library Namespaces" is now called "Show Technology Namespaces" in the pull-down menu, a more accurate name.

  Corrected behavior with respect to saving and loading the "user technology", which is any object without a technology prefix, or with an empty prefix ("::"). This fix also makes sure that if the user technology space is saved to a file, it remembers the connection between the user technology space and that file. XCircuit now considers the following technology names equivalent: NULL, "", "::", and "(user)".

  Also: Also, corrected a problem in which the "New..." and "Delete..." buttons in the parameter edit window would only work for parameters of the current edit page or object. When an instance was selected, all parameter keys and values would refer to the selected instance, but the add/delete function would still refer to the current page. Now, all functions refer to the selected object. Note that the add/delete functions create or delete parameters in the object itself, as opposed to the instance. This might continue to be a cause of confusion.

  ASG (Automatic Schematic Generation, or SPAR: Schematic place & route) updated so that it compiles and runs with the current version. Which is not to say that it actually works, because it still crashes like it used to. However, the SPICE input has been modified to take undefined subcircuits in a SPICE deck and match them to library symbols, and use them. Since the original SPAR was designed for logic symbols, not analog gates, it is much easier to use the same effective netlist (with NAND gates) for both xcircuit and the original SPAR and compare the execution traces.

This problem reveals a second error, which is that a graphic image call in a file to a graphic for which there is no declared data causes a segmentation fault. The segfault issue was corrected first, then the code reworked so that dependent graphic image data are saved at the top of the technology file.

  Also: Modified strokepath so that clipping paths are always drawn when selected, regardless of the global option for showing/hiding clipmasks.
  Also: Added "change color" to the undo/redo mechanism (finally!), and corrected the undo/redo mechanism for style changes so that multiple selections changed in one go are all undone/redone in one go as well (previously, they were assigned incorrectly to individual, sequential undo records).

  2011-04-06 11:04 tim Finished modifications for clip masks and linear gradient fields. Implemented color gradient fields using command "graphic make gradient { } ", which takes color names as well as #RGB syntax. The two color limits get added to the color list, which is not necessarily the right behavior. Corrected clip masking such that clip masks may now be nested in objects, and multiple clipmasks may appear in any object. Modified clipmasks such that clipmask outlines are now shown in light blue, and the outline can be turned off in the options menu to see the view as it will appear in the output file.
  Also: Corrected a missing check for the call stack before attempting to read the contents of said stack.
  Also: (And one other such error.)

  2011-04-04 14:53 tim A number of major changes in this commit: (1) Added new functions for "raise" and "lower" (stack order of elements), and moved the old functions to "top" and "bottom" (move elements to top or bottom of drawing stack). New functions include undo/redo mechanism (still need to apply mechanism to old functions). Added key bindings for "[" and "]" to single-step raise and lower selected elements. There are still some loose ends associated with the new code, that will be tied up shortly. Function is implemented by the Tcl command options "element raise" and "element lower". Old functions changed to Tcl command options "element raise all" and "element lower all". (2) Added clipmask capability. The line/boundary menu now contains a checkbox for "clipmask". Selecting this makes the selected polygon/ arc/curve/path into a clipmask affecting the element above it, which can be any element type. This is particularly effective for cut-out views, with a portion of a graphic image in view behind a path defining the portion of the graphic to be viewed. (3) Added capability to generate in-line graphic images. Initial offering is a black-to-white linear gradient field graphic that can be created with the Tcl command "graphic make gradient { } ". This will be expanded upon shortly, with a menu option or popup GUI for generating various background gradient fields and other simple in-line graphics.
  Also: Small postscript error: did not execute "newpath" after "clip", leading to strange results when the clipping element is followed by another element with a stroke path.

  2011-04-01 06:55 tim Corrected yet another error with the modified selection, where (x, x) was used instead of (x, y) to check for the area selection of graphic images.
  Also: Re-established the drawing of all control point edit lines on path splines.
  Also: Corrected an error with path editing that failed to remove constraints from points on other parts of the path when moving from one edit point to the next.
  Also: Implemented tracking tangents on multiple-curve paths. Control points on two connecting curves track opposite to each other, so that curves meeting at the same angle will continue to meet at the same angle as the control point of one of them is edited. This is now the default edit behavior for curves. The GUI menu item "Options->Elements->Link Curve Tangents" controls the behavior of this setting through the Tcl command line "config pathedit [tangents|normal]". This mode better matches most drawing programs' behavior with regard to paths of linked curves.
  Also: Added new feature for command option "spline make" when one polygon is selected: it converts the polygon into a path of multiple curves, using the endpoints of the polygon as the endpoints of the curve and the remaining polygon points as the curve control points. No particular reason for adding the function other than it seemed easy to do. Convenient way to make complex smooth curve paths, which has never been simple to do in xcircuit before.
  Also: Decided that the convert-to-curve function wasn't such a trivial little thing after all. Added the routine to be called by the "Make Spline" menu function (if a polygon is selected). Fixed the routine to set the path style to be the same as the original polygon. Handled the case of closed polygons. Works very well now to change boxes into rounded-edge boxes.

  2010-11-19 16:34 tim Found a relatively simply way to specify scale-invariant linewidth for object instances. Rather than specifying a linewidth for an instance to apply to all its elements (on an inherited basis, like color is handled), the instance has a "style" record whose single flag is LINE_INVARIANT, indicating that linewidth is scale-invariant (the default). For backward compatibility, in files that are pre-version 3.7, instances at a scale other than 1 are set to scale-variant. All others are set scale-invariant. Files written by 3.7 (as of this revision) will generate a special marker in the output for instances that are set to have scale-variant linewidth.

  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. . .

  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.

  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.

  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.

  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.

  Also: First minor set of corrections to SVG: Corrected color format.
  Also: Added path handling.

  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.

  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.

  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.

  Corrected a number of minor but annoying errors that I have not been able to get around to fixing for a while.

  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.

  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.

  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.

  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.

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.

  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".

  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.

  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.

  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.

  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.

  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.

  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.

  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).

  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.

  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.

  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.

  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 " is used to query a value and "config " is used to set it. The tag callback is set up such that setting an option (3 arguments) invokes the callback procedure, while querying an option value ("config ") does not.
  Also: Changed the reading of paths such that when an endpoint shared between two parts of a path is parameterized, the parameter is applied to both path parts.
• posted: June 5, 2007 at 2:40am     version: 3.6     revision: 95
  2007-06-05 00:27 tim Corrections in response to bugs reported by Seppo Silaste, but which also address similar issues reported by others. Namely, the use of "config search" in the .xcircuitrc file causes xcircuit to crash because xcircuit is no longer able to find font files. The problem was traced to a separate file-open routing for the font encoding files, which would find the encoding and assume the font file would be read correctly, while the actual font file was searched for by libopen(), which would fail to search the fonts/ subdirectory. Both routines have been merged into one, which ensures that a subdirectory called fonts/ is automatically in the search path, and failure to load a font file after an encoding file has been correctly read raises an error condition.

  2007-05-22 21:58 tim Bug fixes from Dimitri Princen (thanks!), for some serious problems like infinite looping when moving an object in a library page, buffer overflow in W0vprintf, and failure to cancel tracking in arc editing.

  2007-04-30 08:19 tim A few changes needed to prevent segfaults while tracking down an error in Tcl-based XCircuit under Ubuntu 7.04.
• posted: April 28, 2007 at 2:40am     version: 3.6     revision: 92
  2007-04-27 16:54 tim Corrected an error from the most recent revision that causes xcircuit to crash when reading a file from the menu where the "library replace" is set to the default "(user)".
• posted: April 23, 2007 at 2:40am     version: 3.6     revision: 91
  2007-04-22 10:44 tim Corrected an error that blows away circles (and random other things, as well) if an "edit arc" operation is canceled with the edited object's radius at zero (i.e., the code that was supposed to prevent the creation of zero-radius arcs was incorrectly called during a cancel operation).
• posted: April 22, 2007 at 2:40am     version: 3.6     revision: 90
  2007-04-21 15:19 tim Restored XCircuit's ability to find the "dot" object when placing a dot at wire crossings, which had become disabled due to the namespace renaming of "dot" to "::dot", causing XCircuit to use filled circles instead of the dot object. Now, XCircuit will find the first object in any technology whose name is "dot".
  Also: 2007-04-21 22:31 tim Also: Corrected an error in tclxcircuit.c that causes XCircuit to crash when running sue_xc.tcl procedure "make_sue_gate".
  Also: Corrected the library object replacement mechanism to act on technologies, not on library pages. Thus, the "-replace" argument to a "load" or "page links load" command should be followed by a technology namespace. Still to be done: Allow a comma-separated list of technology namespaces to replace from, and/or allow multiple uses of "-replace", one for each namespace to replace incoming objects from.

  2007-04-16 22:53 tim Corrected a netlisting error that caused global nets to be broken up into unconnected pieces in the netlist.
• posted: March 23, 2007 at 2:40am     version: 3.6     revision: 86
  2007-03-22 16:02 tim Applied a patch by Greg Warwar that fixes the Tcl netlist format (apparently broken due to recent changes made in the way the netlister subroutine is called).
  Also: Also, corrected an error in the "auto unnumber" routine where a fix was applied in one place but not in the other.
• posted: March 21, 2007 at 2:40am     version: 3.6     revision: 85
  2007-03-20 22:24 tim Corrected the "Make Label" menu command so that it properly reverts to making plain text after one has switched to pin, global, or info label mode. Thanks to Greg Warwar for the bug fix!
• posted: March 15, 2007 at 2:40am     version: 3.6     revision: 84
  Minor correction to the "page links load" command, which did not properly compare filenames against already-loaded symbols and thus could confuse objects with similar names.
• posted: March 10, 2007 at 2:40am     version: 3.6     revision: 83
  Correction to make textpos and textend part of the areawin structure; otherwise, switching between windows during text edit causes XCircuit to get into a confused state.
• posted: March 9, 2007 at 2:40am     version: 3.6     revision: 82
  Additions to the netlister to allow any format to be written to a netlist instead of just "spice", "sim", and "pcb". Adding "flat" to the name forces flattened netlisting instead of hierarchical, for any format (except pcb). Also, corrected the info label parser so that, e.g., "%pX" instead of %p"X" will preserve the ending quote. Also, corrected the netlister so that attempting to generate a netlist from a symbol view does not crash the program.
• posted: March 8, 2007 at 2:40am     version: 3.6     revision: 81
  Corrected a string allocation error in the library object renaming routine.
  Also: Also: Corrected the "write all" function to properly save technology (.lps) files (error was a holdover from the time before library pages and technology files were treated separately).
• posted: March 7, 2007 at 2:40am     version: 3.6     revision: 80
  Corrected a very bad error that causes xcircuit to crash if any object is picked up from a library while the "parameters" menu is mapped. Also, corrected a more subtle error in which XCircuit will confuse a parameter name with an instance name in an input file and incorrectly assume that a label on multiple lines is an instance call.
• posted: February 11, 2007 at 2:40am     version: 3.6     revision: 79
  Changed the analog and analoglib3 libraries on suggestion of Eric Davis to make the "inductor" symbol the same length as the resistor and capacitor symbols, and with the loops centered on the origin.
• posted: January 19, 2007 at 2:40am     version: 3.6     revision: 78
  Implemented left-right scrolling with Shift+(mouse scroll wheel), as per the suggestion from Joel Kuusk.
• posted: January 6, 2007 at 2:40am     version: 3.6     revision: 77
  Corrected an error that prevents instance values of expressions from being copied into a new instance; e.g., when a "quadparts" symbol is picked from the library page. Thanks to Chris Head for the bug report.
  Also: Corrected a bug that causes xcircuit to crash when writing a file with more than one non-default parameter expression in a single instance (in particular, applies to the "LED" symbol).
• posted: January 2, 2007 at 2:40am     version: 3.6     revision: 76
  Corrected the TCL "param" command to fix the error in which creating a substring parameter with the default taken from a selected substring no longer works. Thanks to Chris Head for the bug report.
• posted: December 19, 2006 at 2:40am     version: 3.6     revision: 75
  Added some checks that prevent XCircuit from crashing if no fonts are present.
• posted: December 18, 2006 at 2:40am     version: 3.6     revision: 74
  Minor correction to examples/.xcircuitrc.py so that it points to the correct installation directory for xcircuit-3.6 runtime files. Changed the auto-increment routine to preserve leading zeros, except that I don't like this version, either, and it will likely get changed again until I'm happy with it. Presently, forcing the routine to preserve leading +/- sign and leading zeros causes its behavior to get rather weird when incrementing/decrementing around zero.
• posted: December 9, 2006 at 2:40am     version: 3.6     revision: 73
  Changed the "filelist" widget so that it can accept multiple file extensions for the file filter. Added a check for the ImageMagick "convert" tool in the XCircuit wrapper script. If the command "convert" is found, then the "import graphic image" menu option is allowed to handle all major graphic image types, including other PostScript and PDF, by simply converting to raw PPM format (and discarding the file after reading it in).
• posted: November 29, 2006 at 2:40am     version: 3.6     revision: 72
  Additional refinement to the file writing routine, to avoid unnecessarily printing instance values of expressions that match the default. This cuts down on the output size when expression parameters are used copiously.
  Also: Correction to a misplaced #ifdef...#endif that prevented the non-Tcl version of XCircuit from compiling.
• posted: November 28, 2006 at 2:40am     version: 3.6     revision: 71
  Hopefully the last set of corrections to the expression parameter code. Also supports colors through parameters, at least on a proof-of-concept basis.
  Also: Made changes necessary to implement parameterized colors.
  Also: Finished up changes for parameterized color handling, and added the "LED" digit symbol to the digital library (Tcl version only).
• posted: November 27, 2006 at 2:40am     version: 3.6     revision: 70
  More corrections to the expression parameter handling, especially as relates to the use of expression parameters for numeric parameters such as position.
  Also: 2006-11-27 02:40 tim
• posted: November 26, 2006 at 2:40am     version: 3.6     revision: 69
  Modified parameter handling to allow numerical parameters of elements to be set as expressions from the command-line, and to allow expressions to access specific properties of the object instance (rotation, position, etc.). For example, one can make rotationally-invariant text by selecting a label in an object instance and executing the command "parameter make rotation {expr -%p_rotation}".
  Also: Added some more '%' escapes that can be used in expression parameters to get the values for the scale, rotation, and position of the top-level drawing (thus the expression "expr -%p_rotation" only counter-rotates to the local rotation of the instance in which it occurs, whereas the new expression "expr -%p_top_rotation" is truly rotation-invariant.
• posted: November 24, 2006 at 2:40am     version: 3.6     revision: 68
  Addition to the handling of "quadparts" library components: After determining that two object instances have the same device index, XCircuit checks the pin names for each port in each instance. If any pins have the same pin name at the same port location, it flags the usual warning of "Duplicate component U1 and U1" (say). Otherwise, it ignores the condition.
  Also: Corrected an error that prevents XCircuit from importing from a library that is specified as a full path when the search path has been set.
• posted: November 23, 2006 at 2:40am     version: 3.6     revision: 67
  Corrected the last major error with the graphic image type, which was an incorrect image refcount that would cause the image source to get obliterated while a graphic was still in the drawing (which would cause xcircuit to crash).
  Also: Made an additional change to the graphic image handling, so that XCircuit does a bounds check before recomputing the image at a different scale and/or rotation. Off-screen graphics do not have their target images regenerated.
  Also: 2006-11-23 02:40 tim
• posted: November 22, 2006 at 2:40am     version: 3.6     revision: 66
  Finished corrections to the new behavior regarding expression parameters, especially to fix errors when loading and saving the "quadparts" library.
  Also: Another couple of corrections, mainly to avoid attempting to load a library using the loadfile() routine, when the library is specified on the command line. Also, disallowed the use of "push" in library and page directories, which puts xcircuit in a not-so-useful state.
• posted: November 21, 2006 at 2:40am     version: 3.6     revision: 65
  Corrected the netlister so that the "quadparts" library once again generates correct pcb-style netlists. Added a new method for expression parameters so that "%" will substitute the parameter value prior to executing the expression parameter. This makes it easier to derive parameter values from other parameters without inserting "[param get]" statements and worrying about which level it's executed in. This method was added to the "quadparts.lps" library. Added a new method for "pcb:" info labels. The string "pcb:" may be followed by a space and then any number of statements "=" to declare global pin assignments on the part. For example, "7=GND" sets pin 7 to the global net "GND".
• posted: November 16, 2006 at 2:40am     version: 3.6     revision: 64
  2006-11-15 12:18 tim Corrected the most serious error with graphic images, which was the recalculation of the target image. Instead of having a valid/invalid flag, it now saves the rotation and scale of the target image relative to the top level. On every graphic draw, it compares the rotation and scale against the saved values and determines if the target image needs to be regenerated at the new values. Now it is possible to put graphics inside other objects or have copies of a graphic at different scales and rotations on the same page without causing problems. Also, corrected an error that would automatically merge two schematics into a primary-secondary relationship. Automatic merging should never be done; it should always be an explicit command.
  Also: Completely removed all automatic manipulations of the primary/secondary relationship between schematics. Added the command option "netlist unconnect" to allow a secondary schematic page to be disconnected from its primary (a bit of an oversight to be missing that function. . .)
  Also: Finally corrected the flate decode error on read-in of graphic images (incorrect handling of the final set of characters; the flate encoding of the output was always correct).
• posted: October 24, 2006 at 2:40am     version: 3.6     revision: 63
  2006-10-23 10:18 tim Changed the Makefile.am to reorganize the -L and -l library inclusions. This helps make sure that Tcl/Tk libraries get picked up from the correct place (previously, if a Tcl/Tk version you don't want was installed in the X11 libraries path, then this would be picked preferentially regardless of any specific statements about the path to the version you do want). Thanks to Chris Head for pointing out the problem and helping to debug it.
• posted: October 23, 2006 at 2:40am     version: 3.6     revision: 62
  2006-10-22 18:59 tim Corrected an error in the netlister that exceeds the bounds of a character array due to an incorrect use of "sizeof()". Thanks to Kos Gitchev for the bug report.
• posted: October 20, 2006 at 2:40am     version: 3.6     revision: 61
  2006-10-19 14:11 tim Changed the netlister so that single nets that happen to use bus delimiters are treated correctly as single nets (previously, this condition was flagged as an error and the net name was replaced with an internally-generated node name). Thanks to James Stine for pointing out the error (among others that I haven't gotten around to fixing yet).
• posted: October 14, 2006 at 2:40am     version: 3.6     revision: 60
  2006-10-13 12:27 tim Finally got around to correcting the error that prevents changing a page's filename to an empty string. Doing so is supposed to unlink the page from other pages of the same name, allowing a single page to be broken out of a multiple-page file and saved separately. The "schematics" checkbox button at the top of the file output properties window now works again.
  Also: Changed floating point output to 3 significant digits instead of 2.
• posted: October 2, 2006 at 2:40am     version: 3.6     revision: 59
  2006-10-01 12:33 tim Corrected the handling of the "libinst" keyword in library files to be backwardly-compatible with files that lack technology namespaces.
• posted: September 15, 2006 at 2:40am     version: 3.6     revision: 58
  2006-09-14 15:44 tim Made some changes to the "page" command to allow the option "page -force", which is like "page " unless exceeds the number of existing pages by 1, in which case the command acts like "page make".
• posted: September 14, 2006 at 2:40am     version: 3.6     revision: 57
  2006-09-13 13:30 tim Added a feature to rebind the middle mouse button in text create and text edit modes to paste selections from the system clipboard. The left mouse button continues to finish the text create or text edit operation.
  Also: 2006-09-14 02:40 tim
• posted: September 11, 2006 at 2:40am     version: 3.6     revision: 56
  2006-09-10 07:59 tim Changes to the handling of paths: join, unjoin, and path edit now are all properly handled by the "undo" mechanism. Arcs are not allowed in paths but are decomposed into spline approximations to avoid problems caused by rotations (ellipses in xcircuit don't rotate; probably they should). Path editing has been made more intuitive, and prohibits separating joined points. The "break at point" function during polygon edits has been removed. It will be (but has not yet been) replaced by extending the "unjoin" function to a tool and allowing "unjoin" to act like "break at point" on polygons, and hopefully also on paths, labels, and arcs.
  Also: Another small correction to fix the keybindings printed in the message bar when editing a polygon.
• posted: September 3, 2006 at 2:40am     version: 3.6     revision: 55
  2006-09-02 10:45 tim Corrected an error in file dependency loading: "%n" in a "link" parameter refers to the base object name, not the fully qualified name with technology prefix.
• posted: September 2, 2006 at 2:40am     version: 3.6     revision: 54
  2006-09-01 10:53 tim A number of corrections to the code for moving connected wires along with object instances. Also, expanded the code to move connected wires along with pin labels on the top level (not just pins inside instances). Expanded the code to include connections at wire internal points, and to enforce manhattan layout on such internal points during moves, if the manhattan draw option is selected.
  Also: Correction to polygon/curve/arc editing to correct the "cancel last" operation, which was screwed up by yesterday's code changes.
• posted: September 1, 2006 at 2:40am     version: 3.6     revision: 53
  2006-08-31 16:46 tim Got around to doing one of the long-standing "to do" items: make "attach" work in many more situations. "attach" (Shift-A binding) will now attach wires to pin label position points and to pins inside object instances. If "A" is typed in normal mode, then it starts a wire attached to the closest attachment point. It can also be typed while drawing a wire (not just editing, as before), thus anchoring the point of the wire. Also: Improved the Manhattan wire-drawing mode, so that it is both more intuitive (follows the cursor and adjusts the previous point to maintain the horizontal or vertical alignment of the wire, rather than adjusting the current endpoint), and easier to access the option (duplicated under the line menu in the toolbar). Also: Internal changes to the way editing functions cycle through points in polygons, arcs, splines, and paths should make it relatively easy to implement 1) editing of multiple elements at once, and 2) constrained object instance moves that keep wires attached to pins through the move.
  Also: Implemented pin-constrained movements. If option "Wires Stay Attached to Pins" is selected, then wires whose endpoints terminate on object instance pins are adjusted to stay connected to those pins. This works especially well with the "Manhattan Draw" option. There are a number of refinements that need to be made, but this is a reasonable start.

  2006-08-24 13:11 tim Fixes to remove references to TclCheckBadOctal() (which may or may not be defined by the Tcl shared object library), and to change the reference to the library list widget to the technology list widget in the file load prompt window. Thanks to Jan de Kruyf for the bug reports.
• posted: August 24, 2006 at 2:40am     version: 3.6     revision: 51
  2006-08-23 10:12 tim Corrected the A4 page bounding box (fix by jan de kruyf), and corrected an error in which numerical parameters (those beginning with "p_") were not supposed to get a leading "@" character when printed to the PostScript output (bug report by jan de kruyf).
  Also: Corrects some problems with the library and technology selection from dialog boxes. In particular, it allows newly-created objects to be placed on the library page of choice, and allows both the library page and technology name to be specified when creating a new object. If the current technology is other than "user" or null, then the prefix is automatically printed to the text entry box.

  2006-08-19 20:39 tim Some changes to 1) allow "%n" escapes in info labels to discard technology prefixes from the resulting name, and 2) correctly read unqualified names from the "is_symbol" and "is_schematic" fields in a file and correctly associate the correct symbol and schematic.

  2006-08-13 10:51 tim Corrected handling of "technology save" so that it properly generates the filename, and handles cases where the filename is changed. Updated the "make matching symbol" script so that it properly generates the right technology namespace prefix on new symbols. Thanks to Oliver Banzhaf for the bug reports.
  Also: Applied a patchset by Jan de Kruyf, fixing a couple of missing NULLs in the Tcl option lists, and generally cleaning up the mess I leave behind when I make wholesale changes to the code. Corrected some of the patch code for compliance with the non-Tcl version, as well as a few other changes necessary to get the non-Tcl version to compile.
  Also: Fixed a bug reported by Tony Laneve in which the new method of handling key events disabled the ability to type backslash characters when in LaTeX mode.

  2006-08-03 19:59 tim Another correction from Jan Sundermeyer for the EDIF parser script. The script now correctly handles array labels (labels with bus notation), and label references to global nets (gnd!, vdd!).

  2006-07-30 10:48 tim More of Jan Sundermeyer's additions to the EDIF file reader script. Also, fixed a bug that caused XCircuit to crash on creation of an empty string from the command-line command "label make normal "" {0 0}".

  2006-07-24 14:31 tim Some major changes: 1) Implemented the patch to edif.tcl submitted by Jan Sundermeyer 2) Corrected a few minor errors, such as the output properties window tracking page changes when changed via the number keys 3) Switched over to the analoglib3 library, replacing analoglib2 (finally!). 4) The biggest change: Implemented technology namespaces. XCircuit now **correctly** (barring bugs in the new code) distinguishes between library pages and library files. Each file defines a "technology", and each object in the file gets a name "::
