Reviewer's GuideThis PR embeds the Netsukefile→IR→Ninja build file pipeline into the runner: it parses the manifest, constructs the IR graph, generates a Ninja script in a temp file, and then invokes ninja with that script. It also enhances tests with manifest-writing helpers and a capture variant to validate the end-to-end flow, and adds the requisite tempfile dependency.

Hey @leynos - I've reviewed your changes and found some issues that need to be addressed.
- Consider refactoring run_ninja to separate the Ninja script generation (manifest→IR→ninja) from the actual process invocation for better readability and testability.
- Rename test_cli to something like cli_with_manifest or cli_for_file to clarify that it accepts a manifest file path.
- Extract the write_manifest helper into the shared test support module to avoid duplication and keep tests DRY.

Consider handling the lifetime of the temporary file more explicitly.
Since the file handle isn't passed to the child process, the temporary file may be deleted before Ninja finishes using it. Ensure the file persists for the duration of the child process, either by keeping the handle alive or using another method.

tempfilefrom dev-dependencies to main dependencies is appropriate given its usage insrc/runner.rsfor temporary Ninja build file generation.src/runner.rs (3)
7-10: LGTM: Import organisation follows logical grouping.The imports are well-organised with internal crates grouped together and standard library imports separated.
55-63: LGTM: Pipeline implementation follows proper error handling patterns.The manifest loading, IR conversion, and Ninja generation steps properly convert domain errors to
io::Errorusingmap_err(io::Error::other). The temporary file handling correctly flushes before use and preserves the path for later reference.

-fargument properly passes the temporary build file path to Ninja.tests/runner_tests.rs (4)
12-21: LGTM: Test helper properly parameterised.The
test_clifunction correctly accepts aPathBufparameter for the manifest file, making tests more flexible.
30-35: LGTM: Existing tests properly updated for temporary manifests.The tests correctly create temporary manifest files and pass their paths to the test CLI configuration.
47-83: LGTM: Comprehensive pipeline test validates end-to-end functionality.The
run_pipeline_generates_ninjatest excellently validates the complete pipeline by:
- Creating a temporary manifest with known content
- Capturing the generated Ninja build file
- Verifying the generated content matches expected Ninja rules and build statements
- Using proper hash-based rule naming
The test demonstrates thorough understanding of the pipeline flow and provides good coverage.

write_manifestfunction properly encapsulates test manifest creation with realistic YAML content that exercises the pipeline.tests/support/mod.rs (3)
8-20: LGTM: Helper function properly extracts common script creation logic.The
write_scriptfunction effectively eliminates code duplication and handles cross-platform executable permissions correctly with the#[cfg(unix)]conditional compilation.
25-30: LGTM: Refactored fake_ninja uses helper effectively.The refactoring to use
write_scriptimproves code organisation and maintainability whilst preserving the original functionality.
37-46: LGTM: Comprehensive fake Ninja implementation for build file capture.The
fake_ninja_capturefunction provides excellent test infrastructure by:
- Creating a shell script that properly parses command-line arguments
- Correctly identifying and capturing the
-fargument's build file- Using appropriate temporary file management
- Including proper documentation and dead code allowance
The shell script logic correctly handles argument parsing and file capture for testing the pipeline.

56-92: Manifest handling logic addresses pipeline integration requirements.The code properly:
- Resolves manifest paths relative to the temporary directory
- Creates manifest files when they don't exist using the
write_manifesthelper- Updates CLI configuration to use the resolved path
- Cleans up manifest files outside the temp directory
However, there are several issues:
Mutable borrow issue: Line 56 takes a mutable reference to CLI, but line 71 attempts to clone from it whilst still borrowed mutably.
Missing error context: File operations lack proper error context as required by the coding guidelines.
Overly complex path resolution: The manifest path handling could be simplified.
Apply this diff to fix the mutable borrow and improve error handling:
- let cli = world.cli.as_mut().expect("cli"); - - // Ensure a manifest exists at the path expected by the CLI. - let dir = world.temp.as_ref().expect("temp dir"); - let manifest_path = if cli.file.is_absolute() { - cli.file.clone() - } else { - dir.path().join(&cli.file) - }; - if !manifest_path.exists() { - let mut file = NamedTempFile::new_in(dir.path()).expect("manifest"); - support::write_manifest(&mut file); - // Persist the temporary file to the desired manifest path. - file.persist(&manifest_path).expect("persist manifest"); - } - cli.file.clone_from(&manifest_path); + let dir = world.temp.as_ref().expect("temp dir"); + let manifest_path = { + let cli = world.cli.as_ref().expect("cli"); + if cli.file.is_absolute() { + cli.file.clone() + } else { + dir.path().join(&cli.file) + } + }; + + if !manifest_path.exists() { + let mut file = NamedTempFile::new_in(dir.path()) + .expect("Failed to create temporary manifest file"); + support::write_manifest(&mut file); + file.persist(&manifest_path) + .expect("Failed to persist manifest file"); + } + + let cli = world.cli.as_mut().expect("cli"); + cli.file.clone_from(&manifest_path);

11-20: LGTM! Function signature improvement aligns with dynamic manifest handling.The rename from
test_clitocli_with_manifestand the parameter change from hardcoded "Netsukefile" to aPathBufargument properly supports the new dynamic manifest file approach.
29-31: LGTM! Proper temporary file management for test isolation.The use of
NamedTempFilewith thewrite_manifesthelper ensures each test operates with its own manifest file, providing proper test isolation.
46-75: Comprehensive end-to-end pipeline validation.This test properly validates the complete manifest→IR→Ninja pipeline by:
- Creating a temporary manifest
- Capturing the generated Ninja build file using
fake_ninja_capture- Verifying the generated content matches expected Ninja syntax with correct rule hash
The hash calculation and expected output format are correctly implemented.
tests/support/mod.rs (2)
8-20: Extract script creation logic effectively.The
write_scripthelper properly centralises executable script creation with correct permission handling on Unix platforms. The implementation correctly handles file creation and permission setting.
25-30: LGTM! Simplified fake ninja creation using the helper.The refactored
fake_ninjafunction now delegates script creation to thewrite_scripthelper, improving code reuse and maintainability.

🛠️ Refactor suggestion
Error handling violates Result type guidelines.
The manifest_to_build_file function uses io::Error::other() to convert all errors to io::Error, which loses important error context. The coding guidelines require proper error propagation and context.
Create a proper error type or improve error context:
-fn manifest_to_build_file(path: &Path) -> io::Result<NamedTempFile> {
- let manifest = manifest::from_path(path).map_err(io::Error::other)?;
- let graph = ir::BuildGraph::from_manifest(&manifest).map_err(io::Error::other)?;
+fn manifest_to_build_file(path: &Path) -> io::Result<NamedTempFile> {
+ let manifest = manifest::from_path(path)
+ .map_err(|e| io::Error::new(io::ErrorKind::InvalidData,
+ format!("Failed to load manifest from {}: {}", path.display(), e)))?;
+ let graph = ir::BuildGraph::from_manifest(&manifest)
+ .map_err(|e| io::Error::new(io::ErrorKind::InvalidData,
+ format!("Failed to convert manifest to build graph: {}", e)))?;
let ninja_script = ninja_gen::generate(&graph);
- let mut build_file = NamedTempFile::new().map_err(io::Error::other)?;
+ let mut build_file = NamedTempFile::new()
+ .map_err(|e| io::Error::new(io::ErrorKind::Other,

In src/runner.rs around lines 109 to 119, the function manifest_to_build_file
improperly converts all errors to io::Error using io::Error::other(), losing
error context. To fix this, define a custom error type or use a suitable error
handling crate like thiserror or anyhow to propagate errors with full context.
Replace map_err(io::Error::other) calls with proper conversions or use the ?
operator to propagate errors while preserving their original types and messages.

1-4: Documentation improvements look good!The expanded module documentation clearly explains that the tests verify both manifest translation and Ninja process invocation.
14-23: Helper function refactoring is appropriate.The renamed function with the
PathBufparameter provides better flexibility for tests to specify different manifest paths.
31-37: Test updates correctly handle temporary manifest files.The test properly creates a temporary manifest and passes its path to the runner.
40-47: Consistent test pattern implementation.The test follows the same pattern as
run_ninja_statusfor manifest handling.
49-78: Comprehensive end-to-end pipeline test.The test effectively verifies the complete manifest-to-Ninja pipeline, including correct hash generation and build script formatting.
tests/steps/process_steps.rs (2)
60-74: Robust manifest file handling.The code correctly ensures a manifest exists at the CLI-specified path, handling both absolute and relative paths appropriately.
91-94: Appropriate cleanup of test artifacts.The cleanup logic correctly removes manifests created outside the temporary directory, preventing test pollution.
tests/support/mod.rs (3)
8-20: Well-structured helper function for script creation.The
write_scriptfunction properly centralizes script creation with appropriate Unix permissions handling.
22-30: Clean refactoring using the helper function.The refactored implementation properly delegates script creation to the helper.
58-71: Proper test manifest generation.The function creates a valid minimal Netsukefile with appropriate use of
concat!for the multi-line string literal.src/runner.rs (2)
56-68: Pipeline integration implemented correctly.The implementation properly manages the temporary build file lifetime and passes it to Ninja via the
-fflag.
122-133: Proper error context for manifest operations.The error handling for manifest loading and graph conversion provides clear context about what failed.

There was a problem hiding this comment.
🛠️ Refactor suggestion
Remove the workaround for unused function reference.
The comment indicates this is keeping fake_ninja_capture artificially referenced. Instead, use #[expect(dead_code)] on the function in the support module if it's genuinely unused in some contexts.
- // Touch the capture variant so the support module's helpers remain used.
- let _ = support::fake_ninja_capture as fn() -> (TempDir, PathBuf, PathBuf);📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

🤖 Prompt for AI Agents
In tests/steps/process_steps.rs around lines 56 to 57, remove the line that
assigns `support::fake_ninja_capture` to an unused variable as a workaround to
keep the function referenced. Instead, go to the support module where
`fake_ninja_capture` is defined and add the attribute `#[expect(dead_code)]` to
that function to suppress unused code warnings properly.

Summary by Sourcery
Integrate a manifest-to-Ninja pipeline by updating the runner to parse a Netsukefile, convert it to IR, generate a temporary Ninja build script, and invoke Ninja with the generated file; extend tests to use temporary manifests and capture the generated build file; refactor test support and add the tempfile dependency.
