|Description:||APL based programming system (4.22-1-1004)|
A+ is a powerful and efficient programming language. It embodies a rich set of functions and operators, a modern graphical user interface with many widgets and automatic synchronization of widgets and variables, asynchronous execution of functions associated with variables and events, dynamic loading of user compiled subroutines, and many other features. Execution is by a rather efficient interpreter.
The XEmacs support works pretty well. You'll need a line like (autoload 'a "/sw/share/aplus-fsf-4.20/lisp/aplus" "Start an A+ interpreter session" t) or (load-file "/sw/share/aplus-fsf-4.20/lisp/.emacs") in your .xemacs/init.el file. The former approach is recommended by one who knows better than I citing the loading of A+ support will slow down font handling for all xemacs files. Pressing F4 will start an A+ session with the default APL font, load the A+ menus into the menu bar (i.e. load A+ support). Note that this support is NOT designed for regular emacs. When using an xterm or Terminal.app window with the A+ fonts be sure to turn off istrip (stty -istrip). I've found the font doesn't work in an xterm with tcsh or bash but does with zsh. Even with istrip off tcsh and bash seem to strip the high bit or disable the modifier keys. With zsh the modifier is APPLE/CMD and the shift sense is inverterted even using the supplied XTerm app-default. !!?! Feel free to play around with /sw/share/aplus-fsf-4.20/app-defaults/XTerm and report your results For setting up a Terminal.app window see the A+ FAQ at http://aplusdev.org/FAQ/index.html. The same observations apply with reagrd to choice of shell.
