Is there a method to enable/add these kinds of features in readline to the OCaml toplevel?
I find 2 options that work very well for me:
Another simple way I found is to use the
rlwrap for line editing support: http://www.pkill.info/linux/man/1-rlwrap/
To start the OCaml toplevel with
$ rlwrap ocaml
Or wrap it in a shell script:
#!/bin/sh exec rlwrap /usr/bin/ocaml "$@"
