Overview

Value object representing branch metadata from git branch output

This is a lightweight, immutable data structure returned by branch listing commands. It contains only the data parsed from git output without any repository context or operations.

Examples:

Creating from git branch output

info = Git::BranchInfo.new(
  refname: 'main',
  target_oid: 'abc123def456789012345678901234567890abcd',
  current: true,
  worktree: false,
  symref: nil,
  upstream: nil
)
info.current?     #=> true
info.remote?      #=> false
info.short_name   #=> 'main'

Remote branch

info = Git::BranchInfo.new(
  refname: 'remotes/origin/main',
  target_oid: 'abc123def456789012345678901234567890abcd',
  current: false,
  worktree: false,
  symref: nil,
  upstream: nil
)
info.remote?      #=> true
info.remote_name  #=> 'origin'
info.short_name   #=> 'main'

Local branch with upstream tracking

upstream_info = Git::BranchInfo.new(
  refname: 'remotes/origin/main',
  target_oid: 'abc123def456789012345678901234567890abcd',
  current: false,
  worktree: false,
  symref: nil,
  upstream: nil
)
info = Git::BranchInfo.new(
  refname: 'main',
  target_oid: 'abc123def456789012345678901234567890abcd',
  current: true,
  worktree: false,
  symref: nil,
  upstream: upstream_info
)
info.upstream.remote_name  #=> 'origin'
