ocamlbuild support for Menhir

ocamlbuild support for Menhir

[Joel Reymont]

Is there support for Menhir in ocamlbuild?

Menhir uses the same 'mly' extension as ocamlyacc so I figure I need  
to replace the default rule.

I'm digging around in the ocamlbuild documentation now.

	Thanks, Joel

Please disregard the question. This is described in the User's Guide:

3.21 ocamllex, ocamlyacc and menhir

ocamlbuild knows how to run the standard lexer and parser generator  
tools ocamllex and ocamlyacc when your files have the standard .mll  
and .mly extensions.

If you want to use menhir instead of ocamlyacc, you can either launch  
ocamlbuild with the -use-menhir option or add a true: use_menhir line  
to your _tags file.

The guide says I can put "true: use_menhir" in my _tags file. I tried  
that and this is what I get:

ocamlbuild test.byte --
+ ocamlyacc --raw-depend --ocamldep 'ocamldep.opt -modules'  
easy_parser.mly > easy_parser.mly.depends
usage: ocamlyacc [-v] [-q] [-b file_prefix] filename
Command exited with code 1.
Compilation unsuccessful after building 7 targets (0 cached) in  
00:00:00.

Apparently, ocamlbuild still tries to use ocamlyacc to process  
dependencies. menhir is correctly used with -use-menhir.

I would prefer the _tags option since there's gonna be no way back to  
ocamlyacc for me once I start using menhir's error reporting.

	Thanks, Joel

Yes that's a known bug :(
