In my frenetic efforts to catch all my old APL code up to version 1.8,
here are edif and edif2:
https://github.com/ChrisMoller/edif
In case your personal chronological event horizon is, like mine, less
than two years, edif lets you use terminal-based editors like vim and
nano to create and edit apl functions while edif2 lets you use emacs and
similar editors. (The latter, edif2, works well with aplwrap as well as
with standard terminal-based apl. edif, on the other hand, confuses
aplwrap terribly--aplwrap doesn't understand the full range of terminal
controls terminal editors use.)
Have fun,
