Where +no attribution is made, assume (Hobbs). +------------------------------------------------------------------------- + +THIS FILE IS NO LONGER PERTINENT. + +All changes are now recorded in the ChangeLog. + +---- March 31 1999 v1.6 ---- + +Changed tkConInsert to not use catch (avoids any error generation). + +Changed if check on auto_load in tcl_unknown to an llength on the +args (from [info tclversion]) as 8.0p0 also used just one arg. + +Added -exec command line arg, so that users could do the -exec "" +trick (causes tkcon to skip multi-interpreter model) and makes it +easier to drop tkcon as a console on extended wish executables. + +Changed handling of fixed font for all tkcon text widgets, adding +new -font option, TKCON(font) var, and redoing 'tkcon font'. + +Added color,(disabled|cursor|bg) variables as per Becker's +recommendations, allowing for old defaults. + +Changed multiple instances of string comparisons with llength, +where appropriate. + +Changed dump proc to not try and auto_load a proc arg and improved +recognition of procs in namespaces. + +Added new 'what' proc to environment that tells you what a string +is recognized as. Now used in various other procs. + +Improved hot errors to not pop up edit dialog when the mouse moved. + +---- March 5 1999 v1.5 ---- + +Expanded tkConSave to support use in 'edit'. + +Added tkConGarbageCollect proc for periodic cleanup tasks +(currently, cleaning up error tags in the console widget), +with new gc-delay TKCON var. + +Revised error handling (errors are now hot in the console). + +Changed tkConExpandPathname to recognise that NT for 8.1+ is +case-sensitive, and to not change case for other Windows configs +when no further expansion was made. + +Made changes to tkConEvalOther and the aliasing of tkConEvalAttached +for "Main" for more accurate evaluation. + +Changed the conditional 'update' in tkcon_puts (that overrides the +core puts) to 'update idletasks'. This prevents problems with +using puts in fileevent triggers and such. + +Added check to prevent lower-casing during pathname expansion when +no further expansion can be made on a string. + +New auto-buffer (default 512 lines, set in TKCON(buffer)) for the +console widget. Set this ridiculously high if you liked the +text widget holding all that data. New tkcon buffer method to +go with it. + +Rewrote edit command. Previous version was mostly bogus when used +outside the original slave. + +Change tkcon error to use updated 'edit' command. + +Massaged tkConEvalOther & tkConInterpEval. + +Fixed problem with Show Last Error where a TkCon generated error +was always appearing (from Package Submenu) and moved it above +the packages submenu. + +Removed auto_execok from the slaveprocs list. + +Removed slaveappalias as it didn't work correctly. Made 'edit' +a slavealias, with tkConAttach used to determine where it was +called from + +Changed some regexps around to pass tclCheck's mistaken warnings +(tclCheck's bad matching, not bad regexps). + +Changed dump to not try widgets before commands, as otherwise +it won't automatically complain. + +Fixed pathname completion to only beep when trying to expand on a +non-existent subdirectory (instead of throwing no-directory error). + +Fixed a few notes that TclPro's checker picked up (only one actual +bug in the all switch of 'edit', otherwise it was mostly blowing +wind...). (lvirden) + +---- February 17 1999 v1.4 ---- + +Changed "changes" file to "changes.txt". + +Added edit/more/less proc that allows for the viewing/editing +and returning back to the slave of vars/procs or files. + +Modified history to not got below 0. + +lremove extended with -pattern arg. + +Added code in tcl_unknown to ask about loading Tk when someone tries +a Tk command without Tk being loaded. + +Had to change regexps because \E in Tcl8.1a2 was removed in 8.1b1 (arg!). + +Added "Make Xauth Secure" button for Unix. (heiko.federhenn@stest.ch) + +Fixed tkConInitInterp (used by "Send TkCon Commands") to reattach to +the named namespace when appropriate. + +Fixed bug in popup-menu for Tk8 (bound to wrong toplevel). + +Fixed bug in tcl_unknown confusing auto_load between 8.0 and 7.x. + +Made Interp->Package menu more dynamic, so it recognizes changes in +auto_path and updates itself when Interp is torn-off. + +Removed list from $new in exec redirect for tcl_unknown. (found by Imai) + +Changed package menu to handle multiple package versions. + +Added bogus package require statement to master and slaves to ensure +that pkgIndex.tcl files were properly loaded into interps. + +If "Main" is passed to tkConAttachNamespace, it is interpreted as "::". + +Changed "Attach Namespace" menu to provide a listbox popup when +more than $TKCON(maxmenu) namespaces are present. + +---- June 1998 v1.3 ---- + +fixed long-standing expr bug (missing '$') in tkConSafeBind - found +by TclPro! + +took out the use of tkcon_gets because it only worked for global vars. + +---- March 1998 v1.2 unreleased ---- + +updated regexps in some places to support 8.1 regexps. + +dump now outputs only non-default options for widgets. (ridgway) + +Sorted output list for multiple tab matched items. + +Several minor changes for the plugin (user should see no difference). + +Known problems with dump command understanding namespaces have been +fixed, but only for the 8.0 only version. + +Changed tkConTagProc to recognize ';' as not part of a proc name. + +Changed tkConNew to reuse slave numbers. + +Fixed problem with TKCON(exec) == {} (needed uplevel #0 instead of eval). + +On Mac, tries to source itself using -rsrc (8.0). (nijtmans) + +Changed to use 8.0 menu scheme if possible. (nijtmans) + +Changed tkConInitSlave and tkConNew to only set argv0 in new slave if it +exists (it won't in the plugin). (demailly) + +Changed tkConInit to only checkpoint state once if the slave interp +and main interp are the same (TKCON(exec) == {}). + +---- 08 October 1997 v1.1 ---- + +For Tk8, made TkCon use a fixed font {Courier, size 10} if the current +font is not of fixed type. + +Startup errors should now be found in the TkCon last error function. + +Changed the Triple-1 binding to not include last newline. + +Added fix to make sure that double-evaluation of the command line +didn't occur (might occur for commands that used vwait or something). + +TKCON(errorInfo) is now set with all the errors that occur during start-up, +so that you don't lose stack trace information. + +---- July 03 1997 v1.03 ---- + +Updated namespace eval stuff for Tk8.0b2. + +rewrote tkConSepCmd. + +ls is now "dir -full" by default. + +changed the puts renaming from tcl_puts to tkcon_tcl_puts (so that it +specifies what renamed it). + +added variable highlighting to command highlighting as a background (so +that a command and var can be seen for the same word). + +increased default history size to 48. + +Fixed problem where aliased exit couldn't take extra args. + +replaced old [tkcon gets] with a new UI version to be used with the new +tkcon_gets that, like tkcon_puts, replaces the Tcl gets with a version that +doesn't rely on stdin being present. [tkcon gets] now accepts no args. + **** POTENTIAL INCOMPATIBILITY **** + +---- June 10 1997 v1.02 ---- + +Changed calculator mode commands to be put in the history (but the +output still looks like an error). + +Fixed bug where "source" was assumed to work for primary interp, +causing failure to load in Tk plugin. + +Fixed problem with the id'ing of the primary TkCon interpreter that would +affect attaching to like named interps. + +---- June 8 1997 v1.01 ---- + +minor streamlining in tkConEvalCmd. + +added file menu and separated some items from console menu. + +added support for connecting directly to a namespace (itcl or Tcl8). + +Fixed several potential problems where args to tkConEvalAttached where +not properly protected from eval. + +added slaveexit variable to allow for exit in slaves to be non-destructive, +which is the new default. + +enhanced Tab binding, made Escape the default pathname-only expansion. + +enhanced dump and which commands. + +Removed auto_execok redefinition for Tcl7.5-. TkCon is now intended to +only run in Tcl7.6+ interpreters (though attaching to 7.5- is still OK). + +Added Load/Save menus and expanded Save functionality. + +---- June 1 1997 v1.00 ---- + +TkCon now use virtual events for bindings (REQUIRES TK4.2+) and changed +Console to TkConsole (to not conflict with new Console megawidget). + +Updated tcl_unknown to match Tcl8's unknown. + +Changed handling of preferences directory for macintosh. + **** POTENTIAL INCOMPATIBILITY **** + +Changed tkCon global var to TKCON. + **** POTENTIAL INCOMPATIBILITY **** + +Changed colors to use absolute #RRGGBB format for color-name disadvantaged +systems. + +Removed use of tkCon(font) variable. + **** POTENTIAL INCOMPATIBILITY **** + +Fixed procname expansion to work on/in namespaces. + +Fixed pathname expansion to expand on a directory. + +Fixed all if's to use {}s (better for Tcl8). + +Fixed potential paste problems, it now tries to get the general selection +first, then the CLIPBOARD selection. + +Fixed problem with 'puts' being renamed too early. + +Added calcmode variable to allow typing expr commands write at the tkCon +command line without always saying expr (handled in tkConEvalCmd). + +---- no official release v0.72 ---- + +Changed tkConAbout to use text widget so info could be selected. + +Fixed problem with pathname expansion on windows due to case insensitivity. +(how can anyone work with such an insensitive OS?) + +Fixed off-by-one error in history substitution reported by +<s-imai@lsi.tmg.nec.co.jp>. + +Fixed error in the handling of packages with a space in the name. + +Removed general return of output from rcfile, now only errors are returned. + +New tkConEvent proc to handle event movement, fixed search event problem +where cached event would become incorrect. + +new blinkrange variable to change electric bracing style. + +---- December 20th 1996 v0.71 ---- + +changed to not use upvar for nested arrays (bad for Tcl8). + +catch package require statement for detecting loadable libraries. + +---- November 15th 1996 v0.70 ---- + +Fixed problem with virtual event C/C/P bindings. (reported by +robin@jessikat.demon.co.uk) + +---- November 15th 1996 v0.69 ---- + +Added auto_execok to tkCon(slaveprocs), fixes "unknown" command bug. + +Fix for 'event' to work with plugin. (nijtmans) + +Added '--' and '-filter' options to 'dump'. + +---- November 13th 1996 v0.68 ---- + +Added $tk_library to auto_path for safe slaves loading Tk. (nijtmans) + +Made "r" the default mode for tkConSafeOpen. (nijtmans) + +Changed global delcarations in tkConInit to avoid conflicts with +Nijtmans' plus patch. + +---- November 11th 1996 v0.67 ---- + +Fixed weird backslashing in tkConSafeWindow + +---- November 8th 1996 v0.66 ---- + +Further changes for Tk plugin compatibility.

(nijtmans) + +Reworked tkConFind* to accept optional args. + +Added History menu which display last ten commands in history. + +Removed 'auto_execpath' and changed for new version of 'auto_execok' (in +'which' and 'unknown'), which will be redefined when TkCon is run in Tcl7.5. + +The attached environment is now checkpointed at startup (by default +this is the slave). + +Fixed 'dump var' to use list when printing out nested array elements + +Added 'update' to puts, as well as better error reporting for tcl_puts. +(nijtmans) + +Improved bracing around elseif statements. + +Removed 'warn' alias from distribution. Seemed superfluous. + +Added support for requiring Tk in Tcl8+. + +Made TkCon use tkCon(cols) and tkCon(rows) for startup text size. + +---- September 30th 1996 v0.64 ---- + +Changed the way 'idebug' integrates with TkCon. + +Changed to require Tk of version [expr $tcl_version-3.4]. + +Fixed bug in observe_var (upvar shouldn't have had the \#0). + +Made Interp->Inspect menu disappear if TkConInspect package was not present. + +Made package handling only enabled for Tcl7.5+ interps and reworked +how packages were recognized. + +! Removed virtual events from Console bindings so that they don't screw +! up the Console bindings (temporary fix). + +Changed how initially loaded packages were detected. (nijtmans) + +Made all globals visible in tkConInit. (/nijtmans) + +---- September 23rd 1996 v0.63 ---- + +Changed 'tkConFindBox' to not screw up search string. + +---- September 20th 1996 v0.62 ---- + +Added option for automagically ignoring dead interpreter problems. (wart) + +Fixed bug for reattaching to default slave via menu. (wart) + +Changed how 'observe' spit out trace info for commands. + +Modified 'idebug' internals. + +Made 'idebug' create its own tkCon(exec) slave for maintaining history. + +Fixed long-standing bug in 'lremove' for -all switch. + +Made tkCon(SCRIPT) follow links to the true source script. + +Added 'idebug puts' and 'idebug echo' methods. + +Fixed 'idebug break' to not work at level 0. + +Removed line that could improperly set $name and placed a 'catch' +around the 'interp alias' for 'ls' in tkConInitInterp. + +tkConInit(Slave|Interp) now just 'catch'es the renaming of puts. + +Added 'tkcon set' and 'tkcon upvar' methods. (nijtmans) + +---- September 17th 1996 v0.61 ---- + +Added 'idebug' interactive debugging proc based off Stephen Uhler's all-Tcl +debugger (Oct'95 _Linux_Journal_). Should work w/ or w/o TkCon. + +Added back accidental removal of 'ls' alias in slaves. + +---- September 15th 1996 v0.60 ---- + +Added 'tkcon find str' method and find box to TkCon. + +Added 'observe{_var}' command for simple tracing of vars/cmds with +output in the TkCon console window. + +Reworked tkConFillAppsMenu to be more efficient and correct. + +Added 'echo' as an internal proc and included it in tkCon(slaveprocs). + +Removed tkCon(prompt2). + +Changed tkCon(lightcmd) default to 1 from 0. + +Improved 'tkcon error' to allow it to check the errorInfo of other apps. + +'dump var' now outputs nested array values. (loverso) + +Changed tkCon(Load|Save) to use the new Tk4.2 dialogs if available. + +Fixed tkConPrompt problem where marks were set incorrectly sometimes +when it was called by an event (such as <Control-1>). + +Added bgerror to slaves and 'tkcon bgerror' method. (nijtmans) + +Added tcl_unknown along with other minor mods to get TkCon to work better +with IncrTcl. (nijtmans) + +Made <Triple-1> binding not include the prompt. + +Add null Console bindings for the tkCon(root) bindings to avoid them +getting generated spuriously. (Hobbs / Wart) + +Added -argv/-- command line option. This has very limited use, but is very +good for wrapping TkCon around an existing application which has it's own +command line args. It resets $argv in the main interpreter to what remains +on the command line and TkCon ignores argv. This carries over to any "New +Consoles". + +Reintroduced state procedures, placed them in Interp menu. These should +only be used if you really understand what they do. + +Added 'dump command' method. Usefulness over 'dump proc' is minimal. + +Tightened up the command line args, dropped several optional switches. + +Placed all the Console bindings into tkConBindings, which is called +in tkConInitUI. + +Added 'tkConInitInterp' which places the tkCon shell commands (already +available in any tkCon slave) in the interpreter. It also rewires +puts to send the result back to tkCon. + +Fixed dead attachment problem where attaching to another interp after +being connected to a dead interp would munge the new interp's name. (H / Wart) + +Added 'tkConEvalOther' which evals in the named interpreter. + +Removed 'tkConCheckPackages'. Package handling is now separated into the +autoloading part in tkConInit and into tkConInterpMenu which determines +available static libraries and packages for an interpreter. Menus redesigned. + +Changed 'tkcon eval' to 'tkcon master' since eval gave the wrong connotation. + +Made '-nontcl' option take a TCL_BOOLEAN argument. + +Made 'which' return unknown commands as an error. + +Added button into the help window to send the help URL to netscape. + +Made history substitution spit out a correctly translated command if +evaluation doesn't return an error. + +Changed history search to use the same event id as regular command line +history. + +Added tkCon(meta) variable which varies the Meta definition based on the +platform (Unix == Meta; Win == Alt; Mac == Command) + +Added 'dump widget' method. Spits out current widget state as returned +by '.widget configure'. + +Changed 'dump proc' and 'which' to try and auto_load an unknown procedure. + +Added 'tkcon history' command to return a source'able history stack. + +Fixed off-by-one error in tkConExpand (caused expansion to not work unless +you were expanding the last thing on the line and also not if a special +char was the first on the line). + +Fixed TkCon package handling to work properly for IncrTcl. (nijtmans) + +---- July 31 1996 v0.52 ---- + +Reversed changes file to have newest at top. + +Added 'tkcon version' command. + +Fixed scoping problem when attaching to the master interpreter of a +particular console. + +Rewrote the expansion routines to handle spaces in names better (no longer +requires the user to use grouping as it puts in '\ ' for spaces). + +Fixed off-by-one bug in tkConExpandBestMatch(2). + +Rewired attachments so that when 'send' is used to attach to an app and an +error occurs, TkCon determines whether the app still exists to prevent +multiple errors from arising due to a dead attachment. If this occurs, it +prompts the user on whether to return to the primary slave or to check +periodically for the attached interpreter to come back. tkConEvalSend was +added to facilitate this. + +Command highlighting is now only attempted when a non-empty character is +inserted into the command line (%A != {}). + +Added Ctrl-2 accelerator to get attach to master interpreter of a console +and Ctrl-3 to get to attach to the Main interpreter. + +Made the attachment to Main set the tkCon(app) to Main (to get around the +menu -value {} bug) and also set tkConEvalAttached alias to 'tkConMain eval'. + +Rewrote tkConPrompt to accept "pre" and "post" args to place before and +after the prompt is printed. pre is tagged stdout, post is tagged stdin. + +Rewrote 'dump var' to recognize nested arrays, but not output them +(it's too complicated to do that in source'able form), as well as +recognize empty arrays. + +Rewrote tkConEvalCmd to keep track of errorInfo when errors occur. + +Added 'tkcon error' to display the last errorInfo. + +Changed dumpproc and dumpvar to dump (proc|var) ... + +Added -root argument to set the tkCon(root) variable explicitly. + +Changed the -(slave)eval args to append to rather than set their vars +so that they can be specified multiple times on the command line. + +Added a limit argument to tkConMatch{Quote,Pair}. + +Rewrote dumpvar to recognize a single array value name (ie: a(b)). + +Renamed default non-Unix resource filename from from tkcon.bat to tkcon.cfg. + +No longer 'catch' the renaming of puts in a slave, because we'd want to +know if that threw an error, although it never should... + +---- July 14 1996 v0.51 ---- + +Removed tkConUsage since it was never called. + +Changed tkCon(Load|Save) to use tkFileSelect, if it exists. + +Added -load and -pkg equivalents for -package. + +Added Ctrl-Key-1 binding to reattach to primary slave. + +TkCon now will create itself in a different toplevel if there are already +children of . when tkConInit is called. + +Changed tkConInitSlave not to overwrite tcl_puts in a slave if it exists. + +Created tkCon(slaveprocs) to identify what procs get dumped into a +slave each time and tkCon(slavealias) to identify what will be +aliased back into the main interpreter. + +---- July 4 1996 v0.50 ---- + +Number of history events to keep now set by tkCon(history). + +'unknown' reworked (yet again) to properly handle itself in either the slave +or another interpreter. History substition was moved into tkConEvalCmd and +made an option (via tkCon(subhistory)). + +Inlined _dir into dir/ls. It doesn't save any cycles, but it removes +the need to manage _dir. + +Fixed 'dir/ls -f' to denote executable files with a *. + +Fixed dir/ls to not die on 'dir -f <pattern>'.

The console itself provides +<i>many</i> more features than the standard console. tkcon works on all +platforms where Tcl/Tk is available. It is meant primarily to aid one when +working with the little details inside tcl and tk, giving Unix users the GUI +console provided by default in the Mac and Windows Tk. It's also not a bad +replacement for the default MS-DOS shell (although it needs lots of fine +tuning). +</P> + +<HR NOSHADE SIZE=1> +<ADDRESS><FONT SIZE=2>© Jeffrey Hobbs (jeff at hobbs dot org)</FONT></ADDRESS> + +</BODY> +</HTML> diff --git a/tkcon/install-desktop-menu.sh b/tkcon/install-desktop-menu.sh new file mode 100755 index 0000000..1e4c4eb --- /dev/null +++ b/tkcon/install-desktop-menu.sh @@ -0,0 +1,26 @@ +#!/bin/sh +# +# To install a tkcon entry into a FreeDesktop.org compatible menu system such +# as used by GNOME, KDE or most modern X11 desktop environments the tkcon.desktop +# and icons/* files are installed.
