ocamlbuild and menhir options

[Joel Reymont]

How can I pass additional options such as --infer or --explain to  
ocamlbuild -use-menhir?

	Thanks, Joel

With ocamlbuild --infer is always used. You can give it more flags
using -yaccflags, or through a plugin filling Options.ocaml_yaccflags,
or using some flag declaration using tags such as ("ocaml, "parser",
"menhir").

I tried this but it did not use --explain.

Does the command line look correct?

ocamlbuild -classic-display -yaccflags --explain -use-menhir  
easy_parser.byte

Oops, you're right yaccflags is just for ocamlyacc (I will fix it).

Another solution can be: -ocamlyacc "menhir --explain"

I actually need to run Menhir like this:

menhir --base easy_parser easy_parser.mly easy_tokens.mly

I already have flags like these in myocamlbuild.ml

flag ["ocaml"; "link"] (A"-linkpkg");;
flag ["ocaml"; "link"; "output_obj"] (A"-output-obj");

How would I add the flags for Menhir?

	Thanks, Joel

Instead of giving you the fish, there is a fishing advice!

You should look at the _log file produced by ocamlbuild, there is lines like:
# Target: <filename>, tags: { <tags> }

If you search for the menhir command you will find the tag list
associated (something like ocaml, parser, menhir), then you can add a
flag declaration to inject things a this particular point of the
build.
