Option to generate tags for open windows or buffers only?

[lukelbd]

Hi, thanks for this awesome plugin. Paired with fzf.vim :Tags command it makes project navigation extremely fast.

I was wondering if you would consider adding a configuration option to only generate tags for the currently open windows or buffers instead of whole directory trees. This would speed up tag selection for users that only want to work on a subset of some project (since it would remove irrelevant tags + minimize false positives). This could also help prevent new users from experiencing slowdowns if they haven't yet configured their "project" settings and open vim in a very large directory (e.g. $HOME). This happened to me several years ago and I gave up for a while before returning / reading the docs more carefully.

Thanks. I saw the g:gutentags_project_root_finder option in the docs and set to a custom function, but somehow I missed g:gutentags_file_list_command.

However it looks like g:gutentags_file_list_command only accepts shell commands. Could it be amended to also accept vim function references like g:gutentags_project_root_finder? Then one could easily set it to a function that returns open vim buffers or tabs. Or someone could add a separate g:gutentags_file_list_function option.

Maybe I'll try a PR sometime.

Arguably , you can save the results from vim to a file and do cat from that file.
