Tlsd: Generate (message) sequence diagrams from TLA+ state traces
The GitHub repository hosts the "tla-sequence-diagram" tool for creating sequence diagrams from TLC state traces. It visualizes message exchanges between nodes but needs optimization to prevent overlap. Instructions for usage are provided.
Read original article
The GitHub repository contains information about the "tla-sequence-diagram" tool designed to create sequence diagrams from TLC state traces. This tool assists in analyzing systems where nodes communicate by exchanging messages. It processes state traces into sequence diagrams, illustrating message exchanges between nodes. The tool is not yet optimized to prevent label or line overlap but aims to address this in the future. To use the tool, clone the repository, install it with `pip install .`, navigate to examples, and run `tlc pingpong | tlsd` to generate `sequence.svg`. The tool also supports PDF creation from SVG files using Inkscape. For further inquiries or tasks regarding this tool, users are encouraged to seek assistance.

5 commentsI wrote it to make it more easy to understand why and how some message exchange scenarios failed (in a model) and the charts turned out to be quite helpful for that.
Wish it was easier to express directly in the models, though, or perhaps use this tool without any particular ALIASing, just with better analysis of the trace dumps tlc produces, but parsing TLA+ in general is not that easy. It should be easier to interactively study the state diagrams as well, because non-trivial scenarios can get a lot of states.
