Overview
Yardoc is the default YARD CLI command (+yard doc+ and historic yardoc
executable) used to generate and output (mainly) HTML documentation given a set of source files.
Usage
Main usage for this command is:
$ yardoc [options] [source_files [- extra_files]]
See yardoc –help for details on valid options.
Options File (.yardopts
)
If a .yardopts
file is found in the source directory being processed, YARD will use the contents of the file as arguments to the command, treating newlines as spaces. You can use shell-style quotations to group space delimited arguments, just like on the command line.
A valid .yardopts
file might look like:
--no-private
--title "My Title"
--exclude foo --exclude bar
lib/**/*.erb
lib/**/*.rb -
HACKING.rdoc LEGAL COPYRIGHT
Note that Yardoc also supports the legacy RDoc style .document
file, though this file can only specify source globs to parse, not options.
Queries (--query
)
Yardoc supports queries to select specific code objects for which to generate documentation. For example, you might want to generate documentation only for your public API. If you’ve documented your public methods with @api public, you can use the following query to select all of these objects:
--query '@api.text == "public"'
Note that the syntax for queries is mostly Ruby with a few syntactic simplifications for meta-data tags. See the Verifier class for an overview of this syntax.
Adding Custom Ad-Hoc Meta-data Tags (--tag
)
YARD allows specification of meta-data tags programmatically via the Tags::Library class, but often this is not practical for users writing documentation. To make adding custom tags easier, Yardoc has a few command-line switches for creating basic tags and displaying them in generated HTML output.
To specify a custom tag to be displayed in output, use any of the following:
-
--tag
TAG:TITLE -
--name-tag
TAG:TITLE -
--type-tag
TAG:TITLE -
--type-name-tag
TAG:TITLE -
--title-tag
TAG:TITLE
“TAG:TITLE” is of the form: name:“Display Title”, for example:
--tag overload:"Overloaded Method"
See yard help doc for a description of the various options.
Tags added in this way are automatically displayed in output. To add a meta-data tag that does not show up in output, use –hide-tag TAG. Note that you can also use this option on existing tags to hide builtin tags, for instance.
Processed Data Storage (.yardoc
directory)
When Yardoc parses a source directory, it creates a .yardoc
directory (by default, override with -b
) at the root of the project. This directory contains marshal dumps for all raw object data in the source, so that you can access it later for various commands (stats
, graph
, etc.). This directory is also used as a cache for any future calls to yardoc
so as to process only the files which have changed since the last call.
When Yardoc uses the cache in subsequent calls to yardoc
, methods or classes that have been deleted from source since the last parsing will not be erased from the cache (YARD never deletes objects). In such a case, you should wipe the cache and do a clean parsing of the source tree. You can do this by deleting the .yardoc
directory manually, or running Yardoc without --use-cache
(-c
).
