cgrep --func --var --regex n[aA]m ./cgrep.cpp
```
Pleade do note that the regex will pass through both C++ and the regex engine, so if you would want to escape `\`, the regex you pass as the commandline arg would be `\\\\` instead of the normal `\\`.<br/>
+In order for cgrep to work, you need to have a compilation database, tools like cmake can generate one for you.<br/>
+If your build tool doesn't do that, you can just use [bear](https://github.com/rizsotto/Bear).<br/>
+You can also skipp the compilation database alltogether passing cgrep `--` after the input file name.<br/>
