git grep by file extensions

git grep file-extension
Vinay picture Vinay · Dec 13, 2012 · Viewed 29k times · Source

I know that, if I wanted to grep for a pattern only on files with certain extensions, I could do this:

// searches recursively and matches case insensitively in only javascript files
// for "res" from the current directory
grep -iIr --include=*.js res ./

I've been trying to search for a way to do this via git grep as well (to take advantage of git grep's speed from the indexes it stores with its tree), but to no avail. I saw here that excluding certain file types is not possible.

Yes, for example:

git grep res -- '*.js'
