Version 15 of wish

wish is a simple Tcl/Tk application created during the build process of Tk. It has minimal functionality other than reading files and attempting to execute the Tcl commands inside. It does perform an implicit package require Tk as well as drop the user into an event loop.


Remember that to pass arguments to wish, like display name, etc. the arguments come after the file name to execute AND any arguments before the -- are processed by wish rather than end up in the argv list.


When called with no filename to execute, wish will call the script $(HOME)/.wishrc (under UNIX) if it exists, before dropping into an interactive shell. Under MS Windows, %HOME%/wishrc.tcl is called. Read more about this on The RC File page.


Since Tcl/Tk 8.4 , it is said that wish as an application is no longer necessary; that with tclsh and a

 package require Tk 8.4

one has the complete functionality of this application.

Any comments - any exceptions, caveats, or additional lines you would recommend'to ensure the complete compatibility?

See tclsh vs. wish.

Questions :

  • Does the .wishrc script get interpreted when when tclsh is started and then a 'package require Tk is invoked?
  • No. Setting the tcl_rcFileName to ~/wishrc is a property
     of wish, the application, not Tk, the package.  By the time
     any [[package require Tk]] command got evaluated, the resource
     file for tclsh would have already been [source]d anyway.

People writing scripts to be loaded from the wish command line should be aware that \u001a is an end-of-file character in scripts. I thought this was true for Tcl in general?
