tkconrc - TkCon resource file








TkCon will search for a resource file in
    "~/.tkconrc". TkCon never sources the
    "~/.wishrc" file. The resource file is sourced by each new
    instance of the console. An example resource file is provided below.


The file itself is a Tcl script, so it is required that the file
    conforms to Tcl script conventions.








Certain variables in TkCon can be modified to suit your needs.
    It's easiest to do this in the resource file, but you can do it when time
    the program is running (and some can be changed via the Prefs menu).
    All these are part of the master interpreter's ::tkcon namespace. The
    modifiable array variables are ::tkcon::COLOR and
    ::tkcon::OPT. You can call


tkcon set ::tkcon::COLOR



when the program is running to check its state. Here is an
    explanation of certain variables you might change or use:



  
::tkcon::COLOR(bg)

  
The background color for tkcon text widgets. Defaults to the operating
      system default (determined at startup).

  
::tkcon::COLOR(blink)

  
The background color of the electric brace highlighting, if on. Defaults
      to yellow.

  
::tkcon::COLOR(cursor)

  
The background color for the insertion cursor in tkcon. Defaults to
    black.

  
::tkcon::COLOR(disabled)

  
The foreground color for disabled menu items. Defaults to dark grey.

  
::tkcon::COLOR(proc)

  
The foreground color of a recognized proc, if command highlighting is on.
      Defaults to dark green.

  
::tkcon::COLOR(var)

  
The background color of a recognized var, if command highlighting is on.
      Defaults to pink.

  
::tkcon::COLOR(prompt)

  
The foreground color of the prompt as output in the console. Defaults to
      brown.

  
::tkcon::COLOR(stdin)

  
The foreground color of the stdin for the console. Defaults to black.

  
::tkcon::COLOR(stdout)

  
The foreground color of the stdout as output in the console. Defaults to
      blue.

  
::tkcon::COLOR(stderr)

  
The foreground color of stderr as output in the console. Defaults to
    red.

  
::tkcon::OPT(autoload)

  
Packages to automatically load into the slave interpreter (i.e. 'Tk').
      This is a list. Defaults to {} (none).

  
::tkcon::OPT(blinktime)

  
The amount of time (in millisecs) that braced sections should blink for.
      Defaults to 500 (0.5 secs), must be at least 100.

  
::tkcon::OPT(blinkrange)

  
Whether to blink the entire range for electric brace matching or to just
      blink the actual matching braces (respectively 1 or 0, defaults to
    1).

  
::tkcon::OPT(buffer)

  
The size of the console scroll buffer (in lines). Defaults to 512.

  
::tkcon::OPT(calcmode)

  
Whether to allow expr commands to be run at the command line without
      prefixing them with expr (just a convenience).

  
::tkcon::OPT(cols)

  
Number of columns for the console to start out with. Defaults to 80.

  
::tkcon::OPT(dead)

  
What to do with dead connected interpreters. If dead is leave, TkCon
      automatically exits the dead interpreter. If dead is ignore then it
      remains attached waiting for the interpreter to reappear. Otherwise TkCon
      will prompt you.

  
::tkcon::OPT(exec)

  
This corresponds to the -exec tkcon option (see
    tkcon(1)).

  
::tkcon::OPT(font)

  
Font to use for tkcon text widgets (also specified with -font
      option). Defaults to the system default, or a fixed width equivalent.

  
::tkcon::OPT(gets)

  
Controls whether tkcon will overload the gets command to work with tkcon.
      The valid values are: congets (the default), which will redirect stdin
      requests to the tkcon window; gets, which will pop up a dialog to get
      input; and {} (empty string) which tells tkcon not to overload gets. This
      value must be set at startup to alter tkcon's behavior.

  
::tkcon::OPT(history)

  
The size of the history list to keep. Defaults to 48.

  
::tkcon::OPT(hoterrors)

  
Whether hot errors are enabled or not. When enabled, errors that are
      returned to the console are marked with a link to the error info that will
      pop up in an minimal editor. This requires more memory because each error
      that occurs will maintain bindings for this feature, as long as the error
      is in the text widget. Defaults to on.

  
::tkcon::OPT(library)

  
The path to any tcl library directories (these are appended to the
      auto_path when the after the resource file is loaded in).

  
::tkcon::OPT(lightbrace)

  
Whether to use the brace highlighting feature or not (respectively 1 or 0,
      defaults to 1).

  
::tkcon::OPT(lightcmd)

  
Whether to use the command highlighting feature or not (respectively 1 or
      0, defaults to 1).

  
::tkcon::OPT(maineval)

  
A tcl script to execute in the main interpreter after the slave
      interpreter is created and the user interface is initialized.

  
::tkcon::OPT(maxlinelen)

  
A number that specifies the limit of long result lines. True result is
      still captured in $_ (and 'puts $_' works). Defaults to 0
    (unlimited).

  
::tkcon::OPT(maxmenu)

  
A number that specifies the maximum number of packages to show vertically
      in the Interp->Packages menu before breaking into another
      column. Defaults to 15.

  
::tkcon::OPT(nontcl)

  
For those who might be using non-Tcl based Tk attachments, set this to 1.
      It prevents TkCon from trying to evaluate its own Tcl code in an attached
      interpreter. Also see my notes for non-Tcl based Tk interpreters.

  
::tkcon::OPT(prompt1)

  
Like tcl_prompt1, except it doesn't require you use puts. No
      equivalent for tcl_prompt2 is available (it's unnecessary IMHO).
      Defaults to {([file tail [pwd]]) [history nextid] % }.

  
::tkcon::OPT(rows)

  
Number of rows for the console to start out with. Defaults to 20.

  
::tkcon::OPT(scollypos)

  
Y scrollbar position. Valid values are left or right. Defaults to
    right.

  
::tkcon::OPT(showmenu)

  
Show the menubar on startup (1 or 0, defaults to 1).

  
::tkcon::OPT(showmultiple)

  
Show multiple matches for path/proc/var name expansion (1 or 0, defaults
      to 1).

  
::tkcon::OPT(slaveeval)

  
A tcl script to execute in each slave interpreter right after it's
      created. This allows the user to have user defined info always available
      in a slave.
    
Example:

    
set ::tkcon::OPT(slaveeval) {
    proc foo args { puts $args }
    lappend auto_path .
}
    

  

  
::tkcon::OPT(slaveexit)

  
Allows the prevention of exit in slaves from exitting the entire
      application. If it is equal to exit, exit will exit as usual, otherwise it
      will just close down that interpreter (and any children). Defaults to
      close.

  
::tkcon::OPT(subhistory)

  
Allow history substitution to occur (0 or 1, defaults to 1). The history
      list is maintained in a single interpreter per TkCon console instance.
      Thus you have history which can range over a series of attached
      interpreters.










An example TkCon resource file might look like:


######################################################
## My TkCon Resource File
# Use a fixed default font
#tkcon font fixed; # valid on unix
#tkcon font systemfixed; # valid on win
tkcon font Courier 12; # valid everywhere
# Keep 50 commands in history
set ::tkcon::OPT(history) 50
# Use a pink prompt
set ::tkcon::COLOR(prompt) pink
