Emacs does a wonderful job of disambiguating buffer names when I have several files with the same name open. That is, if I open a single main.cpp, the buffer is simply called main.cpp, but if I open two of them, then one will be main.cpp<foo> and the other main.cpp<bar> (where foo and bar are directories).
This is all fine and good. But there are some file names that are, frankly, worthless on their own. If I'm writing a Python project, __init__.py tells me nothing about what file I'm looking at, and I probably have a couple hundred files with that name in my repo, so I've often had the thought that it would be nice if __init__.py buffers always showed the directory they're in. Likewise, Rust has mod.rs which serves the same purpose and is, as a filename, equally useless.
Is there a whitelist or a regexp that I can use to tell Emacs to always include the directory in the buffer name for files with certain names, even if it's the only file with that name I happen to have open?
M-x ibufferto get the association between a buffer name and the complete pathname, Or justC-x C-fon the buffer without a tag to get the path and thenC-gto abort.C-x C-f C-gall the time :-) and that became tiresome with time.. I founduniquify-min-dir-contentto save me from that tiredness. (It can be set it to a large number for complete pathname.) Hope it helps you too.
