Summary

0005549: add tags for all build-related ocamlbuild command-line options

Description

It would be nice if ocamlbuild tags where "complete" with respect to the command-line option. For example we can call "ocamlbuild -cflag -foo ..." but there is no general tag "cflag(-foo)" -- the "usual suspects" annot, rectypes et al. are relatively well covered by independent tags, but you never know.

Basically, all the -<foo>flag(s) options could be parametrized tags, and the -ocamlc and cousins as well. Other could be included on a case-by-case basis (-just-plugin doesn't make sense, but, say, -no-links could).

Additional Information

Again, this feature was suggested by the confrontation with frontend tools that do not allow to pass ocamlbuild command-line options. Beside, it would help uniformity: I'd rather just write cflag(-rectypes) than remember (or look in `ocamlbuild -documentation`) which specific tag enables -rectypes.

Tags

No tags attached.

Notes
(0007113) gasche (developer) 2012-03-20 11:22	I discussed this with xclerc and mark it acknowledged. Again, patches from the community are welcome.

(0008984) meyer (developer) 2013-03-17 18:57	I agree, but one thought - shall we start adding growing number of command line options, or use the -tags? I'd avoid that. Of course option interface could be generated, and maybe that's a good thing to do.

(0008985) gasche (developer) 2013-03-17 19:02	The problem I was complaining about in this bug report is not that we don't have enough command-line options, rather than it's hard to map some of them into tags (so it is about tags that are missing, not new options to add). If I previously invoked ocamlbuild with some command-line options, and then I decide to instead write a _tag file, it should be easy to express everything I was doing as tags instead of options. So if I used "-clfags -g", I shouldn't have to look in the documentation to find "debug", just write something obvious like cflags(-g). Of course, that doesn't mean that we should remove "debug" or "-tags debug".

(0008986) meyer (developer) 2013-03-17 19:10 edited on: 2013-03-17 19:45	Yes, but my point is that we could keep in sync in a sane way. The way it's implemented is that there is no correlation between them, I proposed in this PR http://caml.inria.fr/mantis/view.php?id=5951 [^] solution to implement options using tags (which is essentially the same as you worked out here earlier)
