Alpha is a text editor, just as powerful and configurable as [Emacs], but having Tcl as extension language instead of [lisp]!  90 percent of Alpha's functionality is written in Tcl, so it is very easy to tweak it and extend it. The AlphaTcl library http://alphatcl.sf.net) is nearly 20000 lines of Tcl code, full of gems and useful tricks.

Joackim Kock: "Alpha's [Tcl] mode is really nice with [syntax] colouring, automatic indentation, [comment] handling, keyword and variable completion, templates insertion, many navigation features (e.g. Cmd-double-click on a proc name and be taken to the place where that proc is defined), and seamless integration with the built-in Tcl interpreter (or an external one if you prefer).  . . . 


Alpha would benefit from getting new Tcl-competent users.  The development of Alpha seems to have stagnated a little bit, but each time there is some feedback and suggestions, there is a burst in development activity..."
