ctags, generate tags using multiple paths?

Question

When I build/update my tags file, ctags starts at the current directory and works its way down recursively.

I would like for it to also include a completely different search path, a mapped network drive, and add those results to my tags file as well.

Is there any way to do that?

Did you read $ man ctags before asking? If so, did you try something? If so, what worked? What failed? If not, do you at least have a theory? — romainl

I did. I understand that I can provide a file with paths to directories, but that means that I would have to hardcode all of my paths in (right?), which I dont want to do. I want one hardcoded path, and the rest to be based off my current directory. — ash

Actually, I think I could just generate tags in the "other" directory manually, they're mostly windows headers and junk so they'll rarely need to be updated, then I could do a set ctags+= /path/to/other/dir, to include another tag file. hooray. — ash

If on linux, you want to create a sym link in your source code dir like ln -s \path\to\linux . and run ctags like ctags --recurse=yes --exclude=.git --exclude=BUILD --exclude=.svn --exclude=vendor/* --exclude=node_modules/* --exclude=db/* --exclude=log/* — oceano1970526

In vim, one can do like below to include the tags file from other directories as well.

:set tags+=/path/to/other/dir/tags

NOTE: Add the tag filename at the end, else there will be "tag not found" error. By default the name is tags but it could be renamed with -f option as below to my_tags when generating it in cli.

$ ctags -f my_tags -R

Now, in vim do

:set tags+=/path/to/other/dir/my_tags

where my_tags is the name of the tag file.

This way any number of tags file can be updated within vim to access them through Ctrl + ] or :tag fnName or similar.

This is great advice. As a follow up, can you do something similar for cscope?
