Me hacking away at things.

Starting to work on a large code base usually involves reading lots of code and building up a mental structure of the code base. There are tools that can aid this process.

Sourcetrail is such a tool which is FOSS, but has been abandoned in 2021. Nonetheless, it still works and is definitely worth trying out! Supported languages are C, C++, Java, and Python.

Usage

The tool needs to index your code base. There is a GUI wizard explaining the process.

The main step is loading the compilation database file compile_commands.json which can be produced via cmake:

cmake -DCMAKE_EXPORT_COMPILE_COMMANDS=ON

Indexing of the 1200 file code base took ~2:30min on my machine. Thereafter, one can search and click through the categories, e.g. Files, Macros, Namespaces, Classes.
