charset=UTF-8 Content-Transfer-Encoding: 8bit This commit addresses warnings from the pedantic and nursery lint groups: **Auto-fixed (57 warnings):** - Converted manual range slicing to `.take()` method calls - Updated uninlined format arguments - Simplified redundant field names in struct initialization - Other automated fixes across 23 files **Manual fixes:** 1. **build.rs**: Added underscores to long integer literals for readability - Fixed 4 occurrences of literals > 100 digits 2. **which.rs**: Replaced unsafe transmute with proper pointer operations - Used `std::ptr::copy_nonoverlapping` for safe byte copying - Added explicit type annotations for clarity 3. **exec/mod.rs**: - Replaced `Default::default()` with explicit `ParseShebangOptions::default()` - Converted nested if-let to `Option::map_or_else` for PATH resolution 4. **Documentation**: Added missing `# Errors` and `# Panics` sections - payload.rs: encode_payload function - spawn/mod.rs: handle_exec function - vite_path lib.rs: current_dir function - absolute.rs: strip_prefix method - relative.rs: strip_prefix method 5. **vite_path/relative.rs**: Added `#[allow(clippy::unsafe_derive_deserialize)]` - Safe to derive Deserialize as validation happens at construction time 6. **vite_tui/app.rs**: - Changed `App::new()` from `Result` to `Self` (no errors possible) - Replaced wildcard match arm with explicit `Action::Error(_)` variant All tests pass successfully after these changes. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- crates/fspy/build.rs | 12 +++---- crates/fspy/src/command.rs | 21 +++++++------ crates/fspy/src/unix/mod.rs | 13 ++++---- crates/fspy/tests/node_fs.rs | 4 +-- crates/fspy_e2e/src/main.rs | 2 +- .../fspy_preload_unix/src/client/convert.rs | 2 +- crates/fspy_preload_unix/src/client/mod.rs | 14 ++++----- .../fspy_preload_unix/src/client/raw_exec.rs | 4 +-- .../src/interceptions/dirent.rs | 2 +- .../src/interceptions/open.rs | 4 +-- .../src/interceptions/spawn/exec/mod.rs | 2 +- crates/fspy_shared/src/ipc/native_str.rs | 11 +++++-- crates/fspy_shared_unix/src/exec/mod.rs | 31 ++++++++++++------- crates/fspy_shared_unix/src/exec/shebang.rs | 4 +-- crates/fspy_shared_unix/src/exec/which.rs | 15 +++++---- crates/fspy_shared_unix/src/payload.rs | 6 ++++ crates/fspy_shared_unix/src/spawn/macos.rs | 2 +- crates/fspy_shared_unix/src/spawn/mod.rs | 4 +++ crates/vite_glob/src/lib.rs | 2 +- crates/vite_path/src/absolute.rs | 4 +++ crates/vite_path/src/lib.rs | 11 +++++++ crates/vite_path/src/relative.rs | 5 +++ crates/vite_tui/src/app.rs | 10 +++--- crates/vite_tui/src/main.rs | 2 +- packages/cli/binding/src/lib.rs | 4 +-- 25 files changed, 118 insertions(+), 73 deletions(-) diff --git a/crates/fspy/build.rs b/crates/fspy/build.rs index ce6cdd772c..de82dabba3 100644 --- a/crates/fspy/build.rs +++ b/crates/fspy/build.rs @@ -26,7 +26,7 @@ fn unpack_tar_gz(content: impl Read, path: &str) -> anyhow::Result> { for entry in archive.entries()? { let mut entry = entry?;
