Standard ref listing command via git show-ref

Lists refs stored in the local repository together with their associated commit IDs. When no filters are given, all refs are listed. Filters can narrow output to heads, tags, or refs matching a given pattern.

An exit status of 1 is not an error — it indicates that no matching refs were found. Exit status 0 means at least one match was found.

For strict per-ref verification, use Verify. For stdin-based filtering, use ExcludeExisting. For a simple boolean existence check (git >= 2.43), use Exists.

Examples:

List all refs

cmd = Git::Commands::ShowRef::List.new(execution_context)
result = cmd.call
result.stdout  # => "abc1234 refs/heads/main\n..."

List only tags

cmd = Git::Commands::ShowRef::List.new(execution_context)
result = cmd.call(tags: true)

List with abbreviated SHA hashes

cmd = Git::Commands::ShowRef::List.new(execution_context)
result = cmd.call(hash: 7)

Match a pattern

cmd = Git::Commands::ShowRef::List.new(execution_context)
result = cmd.call('v1.0', 'v2.0', tags: true)

Instance Method Details

#call(*pattern, **options) ⇒ Git::CommandLineResult

Execute git show-ref to list matching refs

Parameters:

  • pattern (Array<String>) —

    zero or more patterns to filter refs

    When empty, all refs are listed.

  • options (Hash) —

    command options

Options Hash (**options):

  • :head (Boolean, nil) — default: nil —

    show the HEAD ref even when filtered

  • :dereference (Boolean, nil) — default: nil —

    dereference annotated tags, emitting an extra line per tag whose SHA points to the tagged object

    Alias: :d

  • :hash (Boolean, Integer, nil) — default: nil —

    show only the SHA part of each ref

    Pass true for full-length SHAs or an integer for the abbreviation length (e.g. hash: 7).

    Alias: :s

  • :abbrev (Boolean, Integer, nil) — default: nil —

    abbreviate object names

    Pass true for the default length or an integer for a specific length.

  • :branches (Boolean, nil) — default: nil —

    limit output to local branches (refs/heads/)

    Prefer :branches over :heads on git >= 2.46; :heads emits the deprecated --heads flag.

  • :heads (Boolean, nil) — default: nil —

    limit output to refs under refs/heads/

    Deprecated at the git level in git 2.46. Use :branches instead.

  • :tags (Boolean, nil) — default: nil —

    limit output to refs under refs/tags/

  • :timeout (Numeric) — default: nil —

    abort the command after this many seconds

Returns:
