ptksh




SYNOPSIS

         % ptksh  ?scriptfile?
         ... version information ...
         ptksh> $b=$mw->Button(-text=>'Hi',-command=>sub{print 'Hi'})
         ptksh> $b->pack
         ptksh> o $b
         ... list of options ...
         ptksh> help
         ... help information ...
         ptksh> exit
         %


DESCRIPTION

       ptksh is a perl/Tk shell to enter perl commands interac­
       tively.  When one starts ptksh a MainWindow is automaticly
       created, along with a ptksh command window.  One can
       access the main window by typing commands using the vari­
       able $mw at the 'ptksh> ' prompt of the command window.

       ptksh supports command line editing and history.  Just
       type "<Up>" at the command prompt to see a history list.
       The last 50 commands entered are saved, then reloaded into
       history list the next time you start ptksh.

       ptksh supports some convenient commands for inspecting Tk
       widgets.  See below.

       To exit ptksh use: "exit".

       ptksh is *not* a full symbolic debugger.  To debug perl/Tk
       programs at a low level use the more powerful perl debug­
       ger.  (Just enter ``O tk'' on debuggers command line to
       start the Tk eventloop.)


FEATURES

       History

       Press <Up> (the Up Arrow) in the perlwish window to obtain
       a gui-based history list.  Press <Enter> on any history
       line to enter it into the perlwish window.  Then hit
       return.  So, for example, repeat last command is
       <Up><Enter><Enter>.  You can quit the history window with
       <Escape>.  NOTE: history is only saved if exit is "grace­
       ful" (i.e. by the "exit" command from the console or by
       quitting all main windows--NOT by interrupt).

       Debugging Support

       ptksh provides some convenience function to make browsing
       in perl/Tk widget easier:

           no options are given all options of the widget are
           listed.  See Tk::options for more details on the for­
           mat and contents of the returned list.

       o $widget /regexp/
           Lists options of $widget matching the regular expres­
           sion regexp.

       u ?class?
           If no argument is given it lists the modules loaded by
           the commands you executed or since the last time you
           called "u".

           If argument is the empty string lists all modules that
           are loaded by ptksh.

           If argument is a string, ``text'' it tries to do a
           ``use Tk::Text;''.

       Packages

       Ptksh compiles into package Tk::ptksh.  Your code is
       eval'ed into package main.  The coolness of this is that
       your eval code should not interfere with ptksh itself.

       Multiline Commands

       ptksh will accept multiline commands.  Simply put a "\"
       character immediately before the newline, and ptksh will
       continue your command onto the next line.

       Source File Support

       If you have a perl/Tk script that you want to do debugging
       on, try running the command

         ptksh> do 'myscript';

          -- or  (at shell command prompt) --

         % ptksh myscript

       Then use the perl/Tk commands to try out different opera­
       tions on your script.


ENVIRONMENT

       Looks for your .ptksh_history in the directory specified
       by the $HOME environment variable ($HOMEPATH on Win32 sys­
       tems).


FILES

       .ptksh_init
       trounce on them by accident).


BUGS

       Tk::MainLoop function interactively entered or sourced in
       a init or script file will block ptksh.
