== Reference

=== Command Line Options

The following options can be used to control the general behavior of MrDocs and can only be provided via the command line:

[c-preprocessor]
====
[cols="1,2"]
|===
| Name | Description
#define CMDLINE_OPTION(Name, Kebab, Desc) | `pass:[Kebab]` | Desc
include::partial$ConfigOptions.inc[]
|===
====

* Any argument provided to MrDocs without a key is treated as one path in `inputs`.
These can be paths to the configuration file `config`, the `compilation-database` (compilation database or build scripts), or the `source-root` directory.
See the <<common-options>> section for more information on these options.

* The `config` option can be used to explicitly specify a configuration file.
Any path in `inputs` whose filename is `mrdocs.yml` will also be used as the configuration file.
If no configuration file is provided via `inputs` or `config`, MrDocs will attempt to find `mrdocs.yml` in the current directory.

[IMPORTANT]
====
The `config` path is interpreted relative to the current working directory by MrDocs.
All other path options are interpreted relative to the `mrdocs.yml` configuration file.
====

[#common-options]
=== Common Options

The following options can be defined both in the configuration file and on the command line, where the command line options always take precedence.

[c-preprocessor]
[config-options-reference,level=3]
====
|===
| Name | Description
#define COMMON_OPTION(Name, Kebab, Desc) | `pass:[Kebab]` | Desc
include::partial$ConfigOptions.inc[]
|===
include::partial$ConfigOptions.json[]
====

// == Custom commands / Command Aliases
// ALIASES += sideeffect="\par Side Effects:^^"
// ALIASES += l{1}="\ref \1"
// See \l{SomeClass} for more information.
