Gallery of some requested formatters

[hamdanal]

I will use this thread to show some formatters people have requested to be included in rich-argparse

[hamdanal]

A formatter that wraps long lines but does not remove existing line breaks (#78):

import argparse
from rich.containers import Lines
from rich.text import Text
from rich_argparse import RichHelpFormatter

class WrappedTextRichHelpFormatter(RichHelpFormatter):
    def _rich_split_lines(self, text: Text, width: int) -> Lines:
        lines = Lines()
        for line in text.split():
            lines.extend(line.wrap(self.console, width))
        return lines

    def _rich_fill_text(self, text: Text, width: int, indent: Text) -> Text:
        lines = self._rich_split_lines(text, width)
        return Text("\n").join(indent + line for line in lines) + "\n"

A formatter that displays the description and epilog as markdown (#81):

import argparse
from rich.markdown import Markdown
from rich_argparse import RichHelpFormatter

class MarkdownTextRichHelpFormatter(RichHelpFormatter):
    def add_text(self, text: str | None) -> None:  # attention, this affects "description", "epilog", "--version" and maybe other edge cases
        if text is not argparse.SUPPRESS and text is not None:
            self._current_section.rich_items.append(Markdown(text))
