gh-grep

Print lines matching a pattern in repositories using GitHub API

Usage

$ gh grep func.*schema.Schema --include=**/*.go --owner k1LoW --repo tbls
k1LoW/tbls:cmd/doc.go:func withDot(s *schema.Schema, c *config.Config, force bool) (e error) {
k1LoW/tbls:cmd/doc.go:func outputErExists(s *schema.Schema, path string) bool {
k1LoW/tbls:config/config.go:func (c *Config) ModifySchema(s *schema.Schema) error {
k1LoW/tbls:config/config.go:func (c *Config) MergeAdditionalData(s *schema.Schema) error {
k1LoW/tbls:config/config.go:func (c *Config) FilterTables(s *schema.Schema) error {
k1LoW/tbls:config/config.go:func (c *Config) mergeDictFromSchema(s *schema.Schema) {
k1LoW/tbls:config/config.go:func excludeTableFromSchema(name string, s *schema.Schema) error {
[...]

( Do grep the codes (**/*.go) of k1LoW/tbls with the pattern func.*schema.Schema )

$ gh grep --help
Print lines matching a pattern in repositories using GitHub API

Usage:
  gh-grep [PATTERN] [flags]

Flags:
  -e, -- strings         match pattern
      --branch string    branch name
  -c, --count            show the number of matches instead of matching lines
      --exclude string   skip files and directories matching pattern
  -h, --help             help for gh-grep
  -i, --ignore-case      case insensitive matching
      --include string   search only files that match pattern (default "**/*")
  -n, --line-number      show line numbers
      --name-only        show only repository:filenames
  -o, --only-matching    show only matching parts of a line
      --owner string     repository owner or org
      --repo strings     repository name
      --repo-only        show only repositories
      --tag string       tag name
      --url              show URL
  -v, --version          version for gh-grep

⚠️ Notice ⚠️

gh-grep is very slow because it does all its scanning through the GitHub API.

It is recommended to specify the --include option to get the results in a realistic time.
