为C ++项目索引字符串文字

Question

I have a huge c++ project and I find myself rgrep-ing for patterns that I know are in string literals. Is there a way to get clang or x tags or cscope or whatever to build a file with a mapping of each string literal in the project to the file and line where it was found?

Answer 1

I don't know of a way to make cscope or friends to do this. You could almost certainly write a custom Starscope extractor that would do this, if you don't mind writing a dozen or so lines of Ruby (starscope: https://github.com/eapache/starscope , adding an extractor: https://github.com/eapache/starscope/blob/master/doc/LANGUAGE_SUPPORT.md#how-to-add-another-language )

Alternatively it may just be enough to use something like ag instead, which is grep-like but generally a lot faster: https://github.com/ggreer/the_silver_searcher
