See tip 727 for a way to handle local vimrc and tip 804 for upward tag searches.



There's a simpler way to do this for tags:

set tags+=tags;/

Check above tip. It probably should be entirely replaced with the comment above.

Where is this documented in the :help?

:help 'tags' and :help file-searching

Should we delete this tip? Its content is handled in two separate tips. --Fritzophrenic 15:28, May 3, 2011 (UTC)

I haven't had to worry about large trees of source for a while, and have forgotten what all the tags tricks do (although I've got some notes I took on it somewhere, and I'm sure this tip is the wrong approach). The current tip looks unhelpful to me. While mildly interesting, it is essentially an abuse of the system (do you really need a script which does what this appears to do?). I do not understand how VimTip727 has a way to handle local vimrc, but that doesn't matter. We could just replace this with a redirect to Single tags file for a source tree (and I would handle the associated change to the tip number). Is the first comment worth transferring to the target tip? JohnBeckett 07:19, May 4, 2011 (UTC)
