cat test.out | ./ansi2html.sh test.html

Description

Within the typer documentation, termynal is used to interactively show the typer features etc. They are also all styled like the typical terminal output. It would be awesome, if I could replicate this for my typer app documentation.

I tried to capture the terminal styling with several approaches:

• Capture output as html -> didn't work
• Use script to capture the terminal and afterwards use ansi2html -> still no coloring

Is there a way, to get the typer output saved into a file, with the html styling? So I could copy that to my markdown?

This should work

script -q -c "python /tmp/asd.py --help" | ansi2html > asd.html

That being said i guess it would be nice to have something like --color-always option like with the ls-command:

ls -la --color=always | ansi2html > asd.html

Colors appear just fine here, after script -q -c "clitool --help" | ansi2html > clitoolhelp.html and viewing the latter file in a browser.

Another approach is to use the rich export functions:

• export_html
• export_svg
• export_text

If you're using sphinx-doc with reStructuredText, I wrote a directive extension to do this for you. Unfortunately typer has no official way to access the console object, so a monkey patch is involved.

Nice work! Pity, I am trying out Material MkDocs :-/

In case anyone wants to integrate this kind of thing directly into their application, here's an example of a command I created for our Typer application to get the full help output as HTML:

import typer
from typer.cli import docs, state

help = typer.Typer()

@help.command()
def view(ctx: typer.Context):
    """View HTML help for this tool."""

    state.module = HELP_DOCS_TARGET  # e.g. "myapp.main"

    help_docs_gen_dir = Path(tempfile.mkdtemp())
    markdown = help_docs_gen_dir / "help.md"
    html = help_docs_gen_dir / "help.html"

    docs(ctx, name=COMMAND_NAME, title=MAIN_TITLE, output=markdown)

    # Convert Markdown containing Rich console syntax to HTML
    markdown_content = markdown.read_text()
    rich_text = Text.from_markup(markdown_content)
    formatted_markdown_content = Markdown(str(rich_text))

    console = Console(record=True, file=open(os.devnull, "w"))
    console.print(formatted_markdown_content)
    console.save_html(str(html))
    
    print(f"Docs saved to: {html}")
    typer.launch(f"file://{html}")

It's possible this will be greatly simplified and improved with #819
