131-138: LGTM: New tracing field added with clear documentationThe new
tracingfield in theOutputArgsstruct is well-implemented and documented. It provides useful functionality for debugging and understanding the program's behavior. The#[clap(...)]attribute is correctly configured, and the field placement maintains backward compatibility.Consider adding an example of how to use the tracing option in the documentation comment. This could help users understand how to set different tracing levels. For instance:
/// Show tracing information for file/rule discovery and scanning. /// /// This flag helps users inspect ast-grep's internal filtering of files and rules. /// Tracing will output how many and why files and rules are scanned and skipped. /// Tracing information outputs to stderr and does not affect the result of the search. /// /// Example usage: /// ``` /// ast-grep ... --tracing=verbose /// ``` #[clap(long, default_value = "nothing", value_name = "LEVEL")] pub tracing: Tracing,

1-238: Summary: Tracing functionality added successfullyThe changes to this file are minimal and focused, adding a new
tracingfield to theOutputArgsstruct along with the necessary import. The implementation is clean, well-documented, and properly integrated into the existing code structure. These changes enhance the CLI's functionality by providing users with the ability to trace file and rule discovery during execution, which can be valuable for debugging and understanding the program's behavior.As the codebase grows, consider creating a separate module for tracing-related functionality if it becomes more complex. This would help maintain a clean separation of concerns and make the code more modular.

331-331: LGTM! Consider adding documentation for the newtracingfield.The addition of the
tracingfield toOutputArgsaligns with the PR objective of adding tracing to CLI arguments. This change allows for optional tracing functionality with a default configuration.Consider adding a doc comment to explain the purpose and usage of the
tracingfield, which will help users understand its functionality when using the CLI.crates/cli/src/run.rs (1)

201-405: Overall: Excellent implementation of tracing featureThe changes consistently implement the tracing feature across different run modes (
RunWithInferredLangandRunWithSpecificLang), enhancing the CLI tool's ability to track and report runtime statistics. The implementation is well-integrated into the existing codebase and aligns perfectly with the PR objectives.As a minor suggestion for improvement:
Consider adding a brief comment explaining the purpose of the new
tracingfield in theOutputArgsstruct. This would help future maintainers understand the role of this field in the overall statistics tracking feature.crates/cli/src/utils/tracing.rs (1)

52-59: Issue with serializingFileStatscontainingAtomicUsizeDeriving
SerializeandDeserializeforFileStatsmay not work as expected becauseAtomicUsizedoes not implement theSerializeorDeserializetraits by default. This could lead to compilation errors or runtime issues during serialization.Consider implementing custom serialization and deserialization for
FileStatsor switching to thread-safe types that support serialization, such as usingMutex<usize>. Alternatively, you can serialize the values by fetching them from the atomic fields explicitly.use serde::{Serializer, Deserializer}; impl Serialize for FileStats { fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error> where S: Serializer, { let files_scanned = self.files_scanned.load(Ordering::Acquire); let files_skipped = self.files_skipped.load(Ordering::Acquire); let stats = (files_scanned, files_skipped); stats.serialize(serializer) } } impl<'de> Deserialize<'de> for FileStats { fn deserialize<D>(deserializer: D) -> Result<Self, D::Error> where D: Deserializer<'de>, { let (files_scanned, files_skipped): (usize, usize) = Deserialize::deserialize(deserializer)?; Ok(FileStats { files_scanned: AtomicUsize::new(files_scanned), files_skipped: AtomicUsize::new(files_skipped), }) } }

10-10: LGTM! Verify theTracingimplementation.The addition of
Tracingto the public exports is consistent with the PR objective of adding tracing to the CLI argument. This change makes theTracingitem accessible to other parts of the CLI, which is likely the intended behavior.To ensure the

1-394: Summary: Tracing functionality successfully integrated into the scanning process.The changes in this file successfully implement the PR objective of adding tracing to CLI arguments. The modifications include:
- Adding a
tracingfield to theOutputArgsstruct.- Integrating tracing into the
ScanWithConfig::try_newmethod for statistics management.- Updating the
Workerimplementation to print tracing statistics after processing items.These changes enhance the scanning process by providing additional tracing capabilities without disrupting the existing functionality. The implementation appears consistent and well-integrated into the codebase.
To ensure the robustness of these changes, consider adding unit tests specifically for the new tracing functionality, including edge cases and different configuration scenarios.

201-205: LGTM: Enhanced statistics tracking for RunWithInferredLangThe addition of the
statsfield initialized witharg.output.tracing.run_stats()improves the capability to track runtime statistics for theRunWithInferredLangstruct. This change aligns well with the overall goal of enhancing statistics management during execution.
290-296: LGTM: Consistent statistics tracking for RunWithSpecificLangThe addition of the
statsfield initialized witharg.output.tracing.run_stats()for theRunWithSpecificLangstruct maintains consistency with the previous change forRunWithInferredLang. This ensures uniform statistics tracking across different run modes, enhancing the overall capability to monitor runtime performance.
404-405: LGTM: Completed tracing feature with default initializationThe addition of the
tracing: Default::default()field to theOutputArgsstruct in thedefault_run_arg()function completes the implementation of the tracing feature. This ensures that the newtracingfield is properly initialized with its default value when creating a defaultRunArg, maintaining consistency with the rest of the implementation.crates/cli/src/utils/tracing.rs (3)
21-27: LGTM! Tracing enum modifications are appropriateThe addition of the
Nothingvariant with the#[default]attribute correctly sets the default tracing level. DerivingDefault,Serialize, andDeserializeon theTracingenum enhances its usability for default instantiation and serialization purposes.
33-48: LGTM! Added methodsrun_statsandscan_statsare correctly implementedThe
run_statsandscan_statsmethods provide convenient ways to initializeRunStatsandScanStatswith the current tracing level and default values. The implementation is clean and aligns with the design patterns of the codebase.
93-96: LGTM!RuleStatsstruct modifications are appropriateThe
RuleStatsstruct correctly derivesDefault,Serialize, andDeserialize. Removing theDebugderive is acceptable if it's not needed for debugging purposes.
