NAME
       tkconrc - TkCon resource file

DESCRIPTION
       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.

VARIABLES
       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.

EXAMPLES
       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
              ######################################################
