Search Code

Guide for searching the Syncpack codebase effectively.

Golden Rule

Use ast-grep for Rust files — it filters out comments, strings, and docs.

Quick Reference

ast-grep Examples

# Find struct definitions
ast-grep -p 'pub struct $NAME' src/

# Find function calls
ast-grep -p 'Specifier::new' src/

# Find enum variants
ast-grep -p 'pub enum $NAME' src/

# Find impl blocks
ast-grep -p 'impl $TYPE' src/

# Find specific method definitions
ast-grep -p 'pub fn run($$$) -> i32' src/

# Find match expressions
ast-grep -p 'match $EXPR { $$$ }' src/

Pattern Syntax

When to Use grep/rg

# Search across file types
rg "TODO" --type rust --type md

# Search in comments (ast-grep ignores these)
rg "FIXME" src/

# Search non-Rust files
rg "version" Cargo.toml

# Case-insensitive search
rg -i "error" src/

Common Searches

Find where a type is used

ast-grep -p 'Context' src/

Find all InstanceState assignments

ast-grep -p 'InstanceState::valid' src/
ast-grep -p 'InstanceState::fixable' src/
ast-grep -p 'InstanceState::unfixable' src/

Find test files

find src -name '*_test.rs'

Find command implementations

ast-grep -p 'pub fn run($$$) -> i32' src/commands/

Tips

• Start broad, then narrow with more specific patterns
• Use ast-grep output to find the file, then read_file to understand context
• Chain searches: find the type, then find where it's constructed
