I 've been using git specific commands from helm (I think it internally uses vc-git-grep
I find xref-find-definitions work very well. and wonder how xref-find-apropos compare with vc-git-grep
I coulnd't find git specific commands from xref-find-apropos but I might have overlooked something.
Which one is preferable to find some symbols (not necessarily definitions) in a project?
Edit
Never mind, xref-find-apropos uses TAG file..
The main difference is vc-git-grep is always a textual search which will give you matches against all lines in the checked in files.
xref-find-apropos searches for function definitions (and other declarations) with names that match the pattern. But not text inside comments, or even implementation code.
And it delegates the search to the current Xref backend. If the backend uses TAGS (the default one), then it uses TAGS. Otherwise, it uses something else (like the LSP protocol, for example).
