[Caml-list] Readline Support for REPL

[Caml-list] Readline Support for REPL

Hi,

I was wondering if readline support for the OCaml toplevel would be
appreciated. I understand that running the repl with "rlwrap" solves a
similar problem but if we were to implement readline support, we may later
on build on it with tab-completion, etc.

If it is needed, I would be glad to implement support.

readline is licensed under the GPL (not LGPL), so that might have unwanted
consequences for the license of ocaml ...

Note that utop already provides these features and much more:
  https://github.com/diml/utop

I'm not sure improving the toplevel is a good investment of your efforts,
given that there exists such a nice alternative, and that the switching
costs are basically zero for toplevels.

...there also is "ledit" as support for the toplevel-usage.

Maybe utop is what I could try also...

Even though the utop projects provides readline features, wouldn't it make
sense to have basic feature support on the default repl for the language?

Once you try utop, you never go back. ;)

for me the one thing that is sorely lacking in utop is a vi editing mode
like readline has. once you've started to use the shell with nice text
editing support it feels like a handicap to not have it.
