Summary

When generating a DAG or HTML rulegraph, use consistent colours for the different rules (resolves issue #1709).

This PR just sorts the set of rules prior to making the colour map, as sets in Python are enumerated in arbitrary order and this is what leads to the random colour assignment.

QC

I believe any regression should be covered by existing tests (and testing for [in]consistency is very tricky.) I don't see anywhere in the docs that it says the colours will or will not be be randomised each time, so no change needed.

Summary by CodeRabbit

  • New Features

    • Enhanced visual representation of the Directed Acyclic Graph (DAG) with improved rule coloring based on sorted names for consistent output.
  • Documentation

    • Updated comments to clarify the new sorting behavior for rule coloring.

📝 Walkthrough

Walkthrough

The changes made in the snakemake/dag.py file involve modifications to the methods that generate visual representations of the Directed Acyclic Graph (DAG) and its rules. The key alteration is the introduction of sorting rules by name before assigning colors, which ensures a deterministic output for the color representation. This update affects the dot and filegraph_dot methods, with corresponding updates to comments to clarify the new sorting behavior. The overall structure and functionality of the DAG remain unchanged.

Changes

File Change Summary
snakemake/dag.py Updated methods for generating DAG visualizations to sort rules by name before coloring. Adjusted comments to reflect this change.

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>, please review it.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
