Instance Method Details

#[](branch_name) ⇒ Git::Branch?

Returns the branch with the given name

Supports short names ('main'), remote-qualified names ('working/master'), and full refspec names ('remotes/working/master').

Examples:

Look up a branch by short name

repo.branches['main']

Look up a remote-tracking branch

repo.branches['working/master']

Parameters:

  • branch_name (#to_s) —

    the name of the branch to retrieve

Returns:

  • (Git::Branch, nil) —

    the matching branch, or nil if not found

end

#each ⇒ Enumerator<Git::Branch> #each {|branch| ... } ⇒ Array<Git::Branch>

Iterates over every branch in the collection

Overloads:

  • #each ⇒ Enumerator<Git::Branch>

    Returns an enumerator over all branches.

    Examples:

    Get an enumerator over all branches

    enum = repo.branches.each

    Returns:

    • (Enumerator<Git::Branch>) —

      an enumerator over all branches

  • #each {|branch| ... } ⇒ Array<Git::Branch>

    Returns the full list of branches.

    Examples:

    Print every branch name

    repo.branches.each { |b| puts b.name }

    Yields:

    • (branch) —

      passes each branch to the block

    Yield Parameters:

    Yield Returns:

    • (void)

    Returns:

List local branch names

repo.branches.local.map(&:name)

Returns:

end

#remote ⇒ Array<Git::Branch>

Returns all remote-tracking branches

Examples:

List remote branch names

repo.branches.remote.map(&:name)

Returns:

  • (Array<Git::Branch>) —

    the remote-tracking branches

#to_s ⇒ String

Returns a string listing all branches, prefixed with * for the current branch

Examples:

Display all branches

puts repo.branches.to_s

Returns:

  • (String) —

    a formatted branch listing
