📝 Walkthrough

Walkthrough

The documentation has been updated in docs/further.md to improve clarity. The explanatory text regarding the job-specific local storage prefix was split into two sentences, with an added note about escaping environment variables defined only on remote instances. Additionally, the value of the remote-job-local-storage-prefix variable has been modified to escape the $JOBID variable—changing from /local/work/$USER/$JOBID to /local/work/$USER/\$JOBID—to prevent premature evaluation during YAML parsing.

Changes

File	Change Summary
docs/further.md	- Split a sentence explaining the job-specific local storage prefix into two and added a note on escaping remote-only environment variables. - Updated remote-job-local-storage-prefix value to escape $JOBID by using \$JOBID.

21-22: Clarify Explanation for Escaping Remote Environment Variables

The updated text clearly explains that environment variables defined only on remote instances might need to be escaped (using a backslash) to prevent premature evaluation. This addition effectively clarifies why and when such escaping is necessary, aligning well with the PR objectives.

26-26: Verify Correct YAML Escaping for Remote Storage Prefix

The change from /local/work/$USER/$JOBID to /local/work/$USER/\$JOBID is correct and ensures that the $JOBID variable is not evaluated prematurely during YAML parsing. This directly addresses issue #28 and improves usage clarity.

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.
