You get, for each match: the line number (from the beginning of the= =20 file), the byte offset (from the beginning of the file) of the first=20 displayed character, and the context of the match. > > Which will require at least reading the file into memory to convert. > I don't understand what you mean by that, but it seems to me that in any=20 case it's much more efficient than parsing the output of grep with Elisp. And you can easily get the byte offset of each beginning of line with=20 "grep -nbo '^.'", so calculating the byte offset from the beginning of the= =20 line is easy. --fDXorRHs7h--
