Installation

pip install roff
pip install roff[front-matter]  # support for front-matter to configure roff
pip install roff[images]  # support for images
pip install roff[images-svg]  # support for svg-images
pip install roff[watch]  # support for rendering and auto-reloading a manpage while writing

[!TIP] After the installation you should be able to see roff's manpage with man roff or the file format information with man roff.5.

Usage/Execution

For more details inspect the manpage (man roff.1) to see all commands with their options.

For the common usage you can create a template markdown file with the roff template subcommand and then convert it to the roff-file-format with roff convert.

roff --help
roff template command.1.md
roff convert command.1.md
man ./command.1

Additionally, if roff[watch] was installed, you can run roff watch to see the rendered file that automatically re-renders if the file-content changes.

# shell 1
$ roff watch command.1.md
# shell 2
$ nano command.1.md
$ vim command.1.md

Additionally, if your project uses python argparse.ArgumentParser then you can start quicker by using the roff from-parser command instead of roff template. This works almost like the template command, but fills most of the fields.

[!WARNING] from-parser will import the parser from your specified file/module. Which means that the code will be run! Use with care!

$ roff from-parser --root src/ --output prog.1.md myprog.__main__:parser

File Format

For more details inspect the manpage (man roff.5) to see all file specifications.

roff uses markdown as the file format. It supports all commonmark markdown features (h1 is reserved for the head).

Additionally, roff brings 1 own markdown-feature, the inline-command! By prepending your inline-code with a $ sign it gets recognised as an inline-command and rendered in a more special way.

$`command subcommand [--arg value] file...`

[!TIP] Use roff template command.1.md to get a pre-filled markdown file as a starting point.

Configuration

Roff has multiple configuration options for a more customized experience. Details about these options can be inspected via the manpage (man roff.1). These options are only needed for a fine-tuned experience. For most users roff should work out of the box.

Example
