# Conky docs

There are 3 YAML files which contain the documentation:

* [`variables.yaml`](variables.yaml): Documents each object/variable
* [`config_settings.yaml`](config_settings.yaml): Documents global configuration settings
* [`lua.yaml`](lua.yaml): Documents Conky's Lua API

The `desc` field within the docs can be formatted with markdown, however _do
not_ include headings within the `desc` fields, as it will mess up the man page
output. In markdown, headings begin with `#`.

The supported documentation fields are:

* `name`: the name of the thing
* `desc`: a markdown-formatted description of the thing
* `args`: optional list of arguments
* `default`: an optional default value, if applicable

## Updating docs

The man page is based on [`man.md.j2`](man.md.j2) which is a Jinja2 template.
The generated markdown is used to generate a final man page using
[`pandoc`](https://pandoc.org/). Generating the final man page is a 2 step
process:

1. Run `render.py` to process `man.md.j2`:
   ```console
   $ ./render.py man.md.j2 > man.md
   ```
2. Run `pandoc` to convert the markdown into a man page:
   ```console
   $ pandoc --standalone -f markdown -t man man.md > conky.1
   ```

These steps are also part of the CMake build, and can be executed by configuring
the build with `-DBUILD_DOCS=ON`. When building the docs with CMake, target
files are written to the CMake build directory, and not necessarily the same
path as the source files.
