Makefile utility targets for tags

Origin	https://midnight-commander.org/ticket/4195
Reporter	psprint (sg44567@….com)
Keywords	ctags, tags, makefile, make

Hi,
the patch adds three Makefile targets:

• tags-emacs, which generates the TAGS file ↔ the Emacs style tags (actually used by mcedit),
• tags-vim, which generates the tags file with Vim-style tags,
• tags, which generates both above,

… from a curated, well done ctags command invocation, with all the needed options like the recursion and search for C sources and e.g.: proper parsing of the headers (.h). The command is in two forms, first for Exuberant Ctags and the second one for Universal Ctags (there's a check for which one is being found).

Unfortunately, this patch is useless if out-of-source build is used.

I do not understand, could you please explain? Out-of-source build means AFAIK putting compiled objects in a subfolder and I don't see conflict with running ctags via top level Makefile?

The patch is of lesser importance, I thought that such targets would be cool and I'd sent it mostly for my own convenience…

Replying to psprint:

Build tree can be located in any place as far from source tree as you wish.

and I don't see conflict with running ctags via top level Makefile?

Top level Makefile created in the build tree, not in the source one. In the build tree, there are no c/h files excepting config.h, and only config.h is found by ctags.

BTW, the automake's built-in target ctags doesn't support of out-of-source build either.
