Walkthrough

The changes update the exception handling logic in the eval_resource_expression function within src/snakemake/resources.py to catch both NameError and SyntaxError exceptions, instead of only NameError. Additionally, an unused import of logger from snakemake.logging was removed from the same file. The parse_set_resources function in src/snakemake/cli.py was modified to strip surrounding quotes from resource string values. In src/snakemake/profiles.py, stricter validation was added to ensure values are dictionaries in format_two_level_dict, raising a WorkflowError if not. Two test functions in tests/tests.py were modified to include the --cores 1 option in their Snakemake command invocations. New tests, a Snakefile rule, a shell script, and profile configurations were added to test resource quoting behavior.

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.
