Documentarian is a minimal documentation generation tool for Janet projects.

Documentarian makes it easy to take the docstrings you've already written for your code and turn them into a simple Markdown-formatted document. This document can be included in your repository and read easily on services like GitHub.

To install, run:

$ jpm install https://github.com/pyrmont/documentarian

$ /path/to/documentarian

Documentarian depends on your project having a project.janet file that contains a :name key in the declare-project form and a :source key in either the declare-source or declare-native forms. The :source key can be associated with individual files or a directory containing Janet files.

Since the API document is generated in Markdown, you can include Markdown in your docstrings. Don't forget that Janet supports `-delimited long strings in addition to regular "-delimited strings. Long strings preserve whitespace (including newlines) which can be used to create lists, headings and code blocks.

By default, your documentation is saved to a file called api.md in the current working directory. Documentarian includes a simple template that is used to produce the api.md file. You can specify your own template file using the -t command-line argument (see below). The file must be in the Mustache templating language. Documentarian processes the template using Musty. Please note that Musty is an incomplete implementation and does not support the more advanced features of Mustache.

Documentarian supports the following command-line arguments:

 -d, --defix <prefix>       Remove <prefix> from all namespaces.
 -L, --link-prefix <url>    Use <url> as prefix for source code links.

 -x, --exclude <path>       Exclude bindings in <path> from the API document.
 -P, --private              Include private values in the API document.

 -p, --project <path>       Use <path> as project file. (Default: project.janet)
 -l, --local                Set Janet's syspath to ./jpm_tree.
 -t, --tree <path>          Set Janet's syspath to <path>.

 -e, --echo                 Output to stdout rather than output file.
 -o, --out <path>           Use <path> as filename for the API document. (Default: api.md)
 -T, --template <path>      Use <path> as template for the API document.

 -h, --help                 Show this help message.

Clone the repository and then run:

$ jpm [-l] run dev-deps

$ jpm [-l] build

$ jpm [-l] test
