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

Fix the reported failure with the narrowest useful command. Do not turn a targeted repair into repeated full-workspace validation.

Full Presubmit

Run the full presubmit only when the user, task, or approved spec explicitly requires it:

./script/presubmit

This runs formatting checks, linting, and all tests. It is intentionally broader and more expensive than the default implementation workflow.

Individual Checks

Run checks separately when debugging specific issues:

Rust formatting:

cargo fmt -- --check

Clippy (full workspace):

cargo clippy --workspace --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.
