- 17-60: The documentation for the
typebuilt-in command is comprehensive and well-structured, covering synopsis, description, options, operands, standard output, errors, exit status, and portability. It's good practice to include such detailed documentation, as it aids in understanding the command's purpose and usage. However, the options section mentions that non-standard options are not supported yet, which could be expanded upon in the future to enhance the command's functionality.- 64-74: The imports are well-organized and relevant to the functionality of the
typebuilt-in command. It's good to see that only necessary modules and types are imported, which helps in maintaining clarity and reducing potential for unnecessary dependencies.- 94-100: The
mainfunction serves as the entry point for thetypebuilt-in command. It correctly handles parsing the arguments and either executing the command or reporting an error. The use of asynchronous execution and error handling is consistent with the rest of the codebase, ensuring that the built-in command integrates well with the shell's architecture.yash-builtin/src/command/syntax.rs (2)
- 25-25: The introduction of the
OptionOccurrencetype fromcommon::syntaxis a significant change that enhances the representation of options within the shell's syntax parsing framework. This change likely improves the modularity and readability of the code by providing a more structured way to handle options.- 56-68: > 📝 NOTE
This review was outside the diff hunks and was mapped to the diff hunk with the greatest overlap. Original lines [59-101]
The refactoring of the
interpretandparsefunctions to separate parsing and interpretation of command line arguments is a positive change that improves the separation of concerns within the code. By delegating the conversion of parsed arguments into aCommandto theinterpretfunction, the code becomes more modular and easier to maintain. Additionally, the handling of options within theinterpretfunction is clear and straightforward, contributing to the overall readability of the code.yash-builtin/src/command.rs (1)
- 109-113: The addition of documentation to clarify the equivalence of the
typebuilt-in to thecommandbuilt-in with the-Voption is a valuable update. It helps users understand the relationship between these two built-ins and sets clear expectations regarding their functionality. This kind of documentation is crucial for user-facing features and contributes to a better user experience.yash-builtin/src/lib.rs (2)
- 79-80: The conditional compilation of the new
r#typemodule under theyash-semanticsfeature flag is a good practice that ensures the modularity and optional nature of thetypebuilt-in command. This approach allows for flexibility in the shell's configuration and feature set, aligning with the overall design goals of making certain functionalities optional.- 275-282: The addition of the
typebuilt-in command to theBUILTINSarray, also conditionally compiled under theyash-semanticsfeature, is correctly implemented. This change formally integrates thetypebuilt-in into the shell's repertoire of built-in commands. The categorization of thetypebuilt-in asMandatoryis appropriate given its fundamental role in identifying command types. This integration is consistent with the PR's objectives and enhances the shell's capabilities.

The parse function is responsible for parsing the arguments passed to the type built-in command. It introduces a new OptionSpec for verbose identification but does not utilize it directly within the parse function, instead adding it to the options list for interpretation. This approach is somewhat unconventional, as the type command does not inherently support the -V option according to the provided documentation. Consider clarifying the intent behind this implementation or adjusting the documentation to reflect the supported options accurately.
- let spec = OptionSpec::new().short('V').long("verbose-identify");
- options.push(OptionOccurrence {
- spec: &spec,
- location,
- argument: None,
- });Committable suggestion

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation.

Thanks, added a comment in 72e1f07.

@magicant, I've reviewed the changes made in commit 72e1f07. The added comment clarifies the intent behind adding the -V option to the type built-in command, explaining that it's meant to make type equivalent to command -V, thereby delegating to the command built-in. This addresses the initial concern by providing the necessary context for the implementation choice. Thank you for the update.
