|Summary||0005232: wish: -str option for ocaml|
|Description||Sometimes it is useful to be able to run simple oneliner ocaml code without writing the code previously to file. Option -str analoguos to one of camlp4 is wanted.|
I think that this feature doesn't really work:
- the compilers (ocamlc and ocamlopt) need the filename to be used as a compilation unit name, so simply passing code in -str wouldn't work (except if this is only intended for parsing/typing with option -i?)
- the toplevel already makes it easy to work with short pieces of code (in particular `cat "foo;;" | ocaml`), so I'm not sure an -str option to ocaml would make much sense.
ygrek, could you be more specific on the use-cases and semantics you had in mind?
|yes, this was intended exactly as a shorthand for toplevel, but with the following implied features : be usable as script runner, i.e. no extra toplevel output (prompts and types), stdin available for input (with toplevel it results in End_of_file), no reading of ocamlinit (not sure about this one). The intended use-case - running some automated utility tasks (inside project directory) where the actual code is available in a cma or ml file and one-liner is needed to actually call it or run with specific parameters.|

Thanks for the additional information. That seems reasonable. I think it's also reasonable to not run the .ocamlinit, because the "-stdin" option already doesn't do that. In fact I suspect they should both read .ocamlinit, and have a -noinit option (can be obtained as -init /dev/null right now), but that's question that can be handled independently (in fact it is an existing PR: PR#6071).

Indeed; kyoDralliam, could you repost your patch here, using `-str` rather than `-e`?
PS: in case the patch is merged, the name you use in your .patch would be used as attribution information.
|@gasche Could you take care of these two issues?|
