fix-errors

Fix compilation errors, linting issues, and test failures in the warp Rust codebase.

Overview

This skill helps resolve common issues encountered during development, including:

• Compilation errors (unused imports, type mismatches, etc.)
• Linting failures (clippy warnings)
• Formatting violations
• WASM-specific errors
• Test failures

Before opening or updating a pull request, all presubmit checks must pass.

Presubmit Checks

Run all presubmit checks at once:

./script/presubmit

This runs formatting, linting, and all tests. If it passes, you're ready to open a PR.

Individual Checks

Run checks separately when debugging specific issues:

Rust formatting:

cargo fmt -- --check

Clippy (full workspace):

cargo clippy --workspace --exclude warp_completer --all-targets --all-features --tests -- -D warnings
cargo clippy -p warp_completer --all-targets --tests -- -D warnings

WASM Clippy:

cargo clippy --target wasm32-unknown-unknown --profile release-wasm-debug_assertions --no-deps

Objective-C/C/C++ formatting:

./script/run-clang-format.py -r --extensions 'c,h,cpp,m' ./crates/warpui/src/ ./app/src/

All tests:

cargo nextest run --no-fail-fast --workspace --exclude command-signatures-v2
cargo nextest run -p warp_completer --features v2

Doc tests:

cargo test --doc

Running Specific Tests

Single package:

cargo nextest run -p <package_name>

Filter by test name:

cargo nextest run -E 'test(<substring>)'

Specific package with filter:

cargo nextest run -p <package_name> -E 'test(<substring>)'

With output (no capture):

cargo nextest run -p <package> --nocapture

Common Error Types

Unused Imports

Remove unused use statements identified by the compiler.

Unused Constants

Remove constants that are defined but never used.

Unknown Imports

Add the correct use statement for undefined types. Search the codebase to find the correct module path.
