sourcegraph.md

Search code across public repositories using Sourcegraph's GraphQL API.

WHEN TO USE THIS TOOL:

  • Use when you need to find code examples or implementations across public repositories
  • Helpful for researching how others have solved similar problems
  • Useful for discovering patterns and best practices in open source code

HOW TO USE:

  • Provide a search query using Sourcegraph's query syntax
  • Optionally specify the number of results to return (default: 10)
  • Optionally set a timeout for the request

QUERY SYNTAX:

  • Basic search: "fmt.Println" searches for exact matches
  • File filters: "file:.go fmt.Println" limits to Go files
  • Repository filters: "repo:^github.com/golang/go$ fmt.Println" limits to specific repos
  • Language filters: "lang:go fmt.Println" limits to Go code
  • Boolean operators: "fmt.Println AND log.Fatal" for combined terms
  • Regular expressions: "fmt.(Print|Printf|Println)" for pattern matching
  • Quoted strings: ""exact phrase"" for exact phrase matching
  • Exclude filters: "-file:test" or "-repo:forks" to exclude matches

ADVANCED FILTERS:

  • Repository filters:

    • "repo:name" - Match repositories with name containing "name"
    • "repo:^github.com/org/repo$" - Exact repository match
    • "repo:org/repo@branch" - Search specific branch
    • "repo:org/repo rev:branch" - Alternative branch syntax
    • "-repo:name" - Exclude repositories
    • "fork:yes" or "fork:only" - Include or only show forks
    • "archived:yes" or "archived:only" - Include or only show archived repos
    • "visibility:public" or "visibility:private" - Filter by visibility
  • File filters:

    • "file:.js$" - Files with .js extension
    • "file:internal/" - Files in internal directory
    • "-file:test" - Exclude test files
    • "file:has.content(Copyright)" - Files containing "Copyright"
    • "file:has.contributor([email protected])" - Files with specific contributor
  • Content filters:

    • "content:"exact string"" - Search for exact string
    • "-content:"unwanted"" - Exclude files with unwanted content
    • "case:yes" - Case-sensitive search
  • Type filters:

    • "type:symbol" - Search for symbols (functions, classes, etc.)
    • "type:file" - Search file content only
    • "type:path" - Search filenames only
    • "type:diff" - Search code changes
    • "type:commit" - Search commit messages
  • Commit/diff search:

    • "after:"1 month ago"" - Commits after date
    • "before:"2023-01-01"" - Commits before date
    • "author:name" - Commits by author
    • "message:"fix bug"" - Commits with message
  • Result selection:

    • "select:repo" - Show only repository names
    • "select:file" - Show only file paths
    • "select:content" - Show only matching content
    • "select:symbol" - Show only matching symbols
  • Result control:

    • "count:100" - Return up to 100 results
    • "count:all" - Return all results
    • "timeout:30s" - Set search timeout

EXAMPLES:

  • "file:.go context.WithTimeout" - Find Go code using context.WithTimeout
  • "lang:typescript useState type:symbol" - Find TypeScript React useState hooks
  • "repo:^github.com/kubernetes/kubernetes$ pod list type:file" - Find Kubernetes files related to pod listing
  • "repo:sourcegraph/sourcegraph$ after:"3 months ago" type:diff database" - Recent changes to database code
  • "file:Dockerfile (alpine OR ubuntu) -content:alpine:latest" - Dockerfiles with specific base images
  • "repo:has.path(.py) file:requirements.txt tensorflow" - Python projects using TensorFlow

BOOLEAN OPERATORS:

  • "term1 AND term2" - Results containing both terms
  • "term1 OR term2" - Results containing either term
  • "term1 NOT term2" - Results with term1 but not term2
  • "term1 and (term2 or term3)" - Grouping with parentheses

LIMITATIONS:

  • Only searches public repositories
  • Rate limits may apply
  • Complex queries may take longer to execute
  • Maximum of 20 results per query

TIPS:

  • Use specific file extensions to narrow results
  • Add repo: filters for more targeted searches
  • Use type:symbol to find function/method definitions
  • Use type:file to find relevant files
