What's the simplest way to "jump to a file somewhere in my source tree by name"? For example, if I'm working with "libfoo" that contains libfoo/foo/foo.py, I'd like to be able to jump to foo.py from anywhere within libfoo/**[0].
Possibly some way to do this with a tags file?
[0]: that is, libfoo/ and its subdirectories.
check out command-t, FuzzyFinder, or FuzzyFinder_Textmate
Personally, I find command-t has the best UI, but FuF_Textmate is best for quickly getting to the right place in very large projects (which is why I use it after trying all 3)
Note that fuzzyfinder_textmate is unmaintained by its origional author, so you may have to poke around the gh network tab to find who has the most up to date branch. also note it is a bit of a pain to install.
Add ** is to you comma-separated vim path variable (not system path) and if you're in some parent dir of the project use:
:find foo.py
You can use Vim's tab completion of filenames in conjuction with the ** recursive directory expansion.
e.g. type: :e libfoo/**/foo.py and hit TAB. This will search down from the libfoo directory to find a file that matches. If there is more than one match you can cycle through them with the TAB key. When you find the one you want press enter to complete the command and edit the file.
For more about the ** matching do :h starstar. It requires a version of Vim compiled with the +path_extra option.
If you have already edited the file once you can also search the buffers for partial name matches with the :b name command. e.g. :b foo.py<TAB> will expand to a buffer name that has 'foo.py' anywhere in it. N.B. it matches the entire path, so :b foo<TAB> would match all buffers with files from the libfoo directory.
