What's Changed

• Quick fixes 4.x by @kmvanbrunt in #1651
• Remove always_show_hint settable by @tleonhardt in #1652
• Overhauled redirection and output capturing by @kmvanbrunt in #1654
• Fixed default value for traceback_show_locals. by @kmvanbrunt in #1655

• Breaking Changes
  • Removed always_show_hint settable as it provided a poor user experience with
    prompt-toolkit
  • cmd2 redirection only captures output directed to self.stdout (e.g., via
    self.poutput()). Standard print() calls write directly to sys.stdout and are not
    captured. However, print() calls within pyscripts and the interactive Python shell are
    treated as command output and sent to self.stdout, allowing them to be captured.
  • Verbose help table descriptions are no longer generated from help function output. The system
    now relies exclusively on command function docstrings.
• Enhancements
  • Added HelpFormatterRenderable protocol and HelpContent type alias to support context-aware
    help content in argparse.
  • The print() function available in a pyscript writes to self.stdout and respects the
    allow_style setting. It also supports printing Rich objects.
  • Added Cmd2ArgumentParser.output_to() context manager to temporarily set the output stream
    during argparse operations. This is helpful for directing output for functions like
    parse_args(), which default to sys.stdout and lack a file argument.
• Bug Fixes
  • Fixed ArgparseCompleter.print_help() not passing file stream to recursive call.
  • Fixed issue where constants.REDIRECTION_TOKENS was being mutated.
