📝 Walkthrough

Walkthrough

This change updates the documentation in the source/_docs/scripts.markdown file to clarify the behavior of variable scopes and parallelized actions. The local scope for variables now explicitly applies only to those defined by the variables action. Additionally, it is now clearly documented that response data from parallelized actions can be accessed outside their own scope. There are no modifications to exported or public entities.

Changes

File Change Summary
source/_docs/scripts.markdown Clarified that local scope applies only to variables defined by the variables action and noted that response data from parallelized actions is accessible outside its own scope.

🪧 Tips

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.

861-862: Refine Parallel Action Response Data Text
The new lines explaining that the response data of a parallelized action is available outside its scope are generally clear. However, consider streamlining the wording to remove redundancy and fix trailing whitespace. For instance, you might rephrase the text as follows:

- - The response data of a parallelized {% term action %} is however also available outside of its own scope. This is especially useful for parallelizing execution of long-running {% term actions %}. 
+ - The response data of a parallelized {% term action %} is also available outside the action's scope. This is especially useful for parallelizing the execution of long-running {% term actions %}.

This edit removes the redundant phrase "its own" and addresses the trailing space issue.

97-97: Clarify Local Variable Scope
The updated sentence clearly explains that variables defined via the variables action have a local scope—that is, changes in a nested sequence do not affect an outer block. This clarification is in line with the PR objectives and should help users understand variable isolation better.
