When I described how I use Ugrep in
Emacs I forgot to
mention something. It’s true that I rely on
project-find-regexp (C-x p
g) for searches, but there is a specific use-case where this command is
not as handy as it usually is: project-wide navigation.
To be more precise, in my daily workflows it can happen that all I need to do is
jump to a different file where the thing at point is used. The power of
project-find-regexp is too much here, because I don’t need the
with all the results and the ability to replace them. I just want a quick a way
to hit RET on the candidate I am looking for and move to the desired
xref-search-program set to
'ugrep1 the solution is trivial.
(defun mu-project-find-regexp () "Use `project-find-regexp' with completion." (interactive) (defvar xref-show-xrefs-function) (let ((xref-show-xrefs-function #'xref-show-definitions-completing-read)) (if-let ((tap (thing-at-point 'symbol))) (project-find-regexp tap) (call-interactively #'project-find-regexp))))
The trick is temporarily setting
xref-show-definitions-completing-read, which according to its documentation
does exactly what I am looking for.
Let the user choose the target definition with completion.
When there is more than one definition, let the user choose between them by typing in the minibuffer with completion.
I then bind
mu-project-find-regexp to M-? and all is set. Needless
to say, the heavy work is still done by
project-find-regexp. Such an awesome
Note that I am overriding the default M-? on purpose, because the
xref-find-references does not take things like
account, something absolutely necessary in large projects where I want to avoid
having useless candidates spam the ever precious minibuffer.
Finally, be aware that a better version of
mu-project-find-regexp can be found
