Ren’Py is a tool to build interactive novels from code.

In these novels, the player/reader must choose between different choices. This leads to a tree structure. It is not easy to have an accurate and correct view of the story that is written from the pure code.

I needed a tool to organize my 10k+lines Ren’Py project.

So I created my own tool in #Go.

It is a text analyser that draws a graph of the project from its source code. Here is an extract of the graph that can be generated:

What I learned:

• Go data structures (struct, map) and methods over a type
• RegEx a lot
• Go cross-compilation
  • Cross-compilation is hard when using a C library
• Graphviz, a graph library
• dot language, used along with graphviz
