.generate(config, executor: Atoms::CommandExecutor) ⇒ String

Generate diff based on configuration

Parameters:

  • config (Models::DiffConfig) —

    Diff configuration

  • executor (Module) (defaults to: Atoms::CommandExecutor) —

    Command executor (default: Atoms::CommandExecutor)

Returns:

  • (String) —

    Raw diff output

# File 'lib/ace/git/molecules/diff_generator.rb', line 14

def generate(config, executor: Atoms::CommandExecutor)
  # Handle special cases first
  return executor.staged_diff if config.format == :staged
  return executor.working_diff if config.format == :working

  # Determine what to diff
  range = determine_range(config, executor)

  # Build git diff command
  cmd_parts = build_command(range, config)

  # Execute with configured timeout
  result = executor.execute(*cmd_parts, timeout: config.timeout)
  handle_result(result, cmd_parts)
end

.generate_for_range(range, config, executor: Atoms::CommandExecutor) ⇒ String

Generate diff for a specific range

Parameters:

  • range (String) —

    Git range (e.g., “HEAD~5..HEAD”, “origin/main…HEAD”)

  • config (Models::DiffConfig) —

    Configuration options

  • executor (Module) (defaults to: Atoms::CommandExecutor) —

    Command executor

Returns:

  • (String) —

    Diff output

  cmd_parts = build_command(range, config)
  result = executor.execute(*cmd_parts, timeout: config.timeout)
  handle_result(result, cmd_parts)
end

.generate_numstat(config, executor: Atoms::CommandExecutor) ⇒ String

Generate ‘git diff –numstat` output for structured file statistics. Uses the same range/path/flags logic as the main diff generation path.

Parameters:

  • config (Models::DiffConfig) —

    Diff configuration

  • executor (Module) (defaults to: Atoms::CommandExecutor) —

    Command executor (default: Atoms::CommandExecutor)

Returns:

  • (String) —

    Numstat output

  handle_result(result, cmd_parts)
end

.generate_since(since, config, executor: Atoms::CommandExecutor) ⇒ String

Generate diff since a date or commit

Parameters:

  • since (String) —

    Date or commit reference

  • config (Models::DiffConfig) —

    Configuration options

  • executor (Module) (defaults to: Atoms::CommandExecutor) —

    Command executor

Returns:

  • (String) —

    Diff output

  range = "#{since_ref}..HEAD"

  generate_for_range(range, config, executor: executor)

.staged(config, executor: Atoms::CommandExecutor) ⇒ String

Get staged diff with configuration

Parameters:

  • config (Models::DiffConfig) —

    Configuration options
