By default, the function-finding isn't aware of the specific content in
the file. But you can associate extensions with particular types, like:
$ echo '*.cpp diff=cpp' >~/.gitattributes
$ git config --global core.attributesFile ~/.gitattributes
$ git grep --no-index --show-function -e FOO test2.cpp
test2.cpp=int main() {
test2.cpp: FOO
test2.cpp: FOO
Usually this is done in-repo, but since your example used --no-index, I
showed how to set up a per-user attribute file. The "diff" attribute
covers both diff and grep (for diff, the hunk headers will also show the
function).
The "cpp" diff regexes are built-in to the git binary. We just don't
associate any filenames by default. You can also add your own; see the
section "Defining a custom hunk-header" from "git help attributes".
