Just use rlwrap (installed on ZID machines). Either call
ocaml as follows:
$ rlwrap ocaml
or set following alias (e.g., in your .bashrc):
alias ocaml="rlwrap ocaml"
How to use ocamlbuild?
There a different applications of ocamlbuild:
- Compiling the file
prog.mlas bytecode executable:
$ ocamlbuild prog.byte - Compiling an interpreter
name.topin which some modules are preloaded. First create a filename.mltopcontaining one module per line that should be preloaded on startup. Second
$ ocamlbuild name.top
How can I customize my own interpreter?
Every time an interpreter is started (either ocaml or
something like name.top from above) the current directory
is checked for the file .ocamlinit. If it exists, its content
is executed as if you would have typed it in the interpreter. (Alternatively
the flag -init <file> can be used to load the file
<file>.)
This is for example useful to change to the directory _build
on startup (which is the default output location of ocamlbuild).
The corresponding toplevel directive is #cd "_build";;.
