If the symbolic values are specific to project, simply let-bind uniquify-dirname-transform to the value of the appropriate project.el defcustom when project.el calls uniquify.These customizations are in effect all the time, not just when the user is calling a project.el command. e.g. rename-buffer triggers uniquify.Then you can set the buffer-local value of uniquify-dirname-transform in the project.el buffers. Would that solve the problem?The buffers it should affect are all file-visiting buffers. project.el doesn't currently have any code which runs for every new buffer. I guess we've considered adding that, but I'm not sure this is a good reason...
I'm not sure every project.el user will want this particular behavior anyway. project-switch-buffer is handy, but personally, I still most often use 'C-x b'.
But there definitely is demand for this option, as evidenced by the previously mentioned bug#59502, as well as this (unexpectedly, years-old) thread: https://lists.gnu.org/archive/html/emacs-devel/2021-03/msg00083.html
Speaking of those, do you think it would be feasible to also offer these tweaks (as options, or for particular buffers):
- Make the presence of the buffer name mandatory. As shown in the examples in bug#59502, it could be useful to always see in buffers like *eshell* produced by project-eshell. Or project-vc-dir, for example.
- Hide the parent directory from the uniquification logic (only keeping the project name). So that, for example, if I call 'M-x project-eshell' and then 'C-u M-x project-eshell', the generated buffer names would not try to use the parent segment to uniquify, and just stay as <project-name>/*eshell* and <project-name>/*eshell-2*. There is currently some bespoke logic for naming these particular buffers, but if we could move to uniquify (and obey its custom vars), that would probably be an improvement.
