git log regex search

Question

I just found out the differences between git log --all -G "mystring" and, git log --all -S "mystring" as you can see here, for example.

But, I'd like to know if I can specify several regular expressions (a.k.a. regex) to -G, with something like: git log --all -G "str1" --and -G "str2"

Of course, I can always wrap git commands inside python or bash scripts, but I'd like to know if using pure-git-commands, I can do this.

Thanks very much!!

Not quite an answer, but: -S takes a string while -G takes a regex (already), and you can make the -S argument a regex by adding --pickaxe-regex. See the gitdiffcore documentation: kernel.org/pub/software/scm/git/docs/gitdiffcore.html - and then note that "exp1 AND exp2" is almost (but not exactly) "(exp1.*exp2)|(exp2.*exp1)" in "regex algebra". — torek

To search the commit log (across all branches) for the given text:

git log --all --grep='String'

so

git log --grep=str1 --grep=str2

will list commits mentioned either str1 or str2 in their commit log messages

Should also show the --all-match option, which ANDs all of the --greps
