Changing the APL prompt ?

[Emmanuel Charpentier]

Dear list,

Is there a way to change the APL standard prompt (i. e. 6 spaces at the start of a line) ?

I'd like to develop two interfaces that may, IMHO, improve the usefulness of APL in today's use :

• A Jupyter kernel, allowing its use in Jupyter notebooks,
• An org-babel driver, allowing its use in Org documents.

Both are (semi-)trivial to write (thoanks to expect and pexpect), except for recognition of "end-of-output", which might be eased by assigning a predetermined random value to the (final) prompt. QuadEB and Quad-EA come to mind...

Any hint ?
