Re: [Bug-apl] Calling external editor from APL session

[Juergen Sauermann]

Hi Alexey,

it is possible though not very convenient:. You could write
a function doing the following:

1. read EDITOR with ⎕ENV (or use vim right away)
2. call your editor using )HOST or with popen() via ⎕FIO
3. read the file produced by the editor with ⎕FIO
4. ⎕FX the the function text read.

You can optionally bind that function to a user defined command.

Another option could be Blake McBride's editor written in APL,
see http://www.gnu.org/software/apl/Community.html

Or Elias' emacs mode for GNU APL.

Hi,

Is it possible to call external editor to edit function when using GNU
APL? For example I would like to call Vim when I want to modify the
function.
For example in Dyalog there is an )ed command:

I'm looking at something like this for GNU APL but just calling whatever
is set in the EDITOR variable.
