Class | YARD::Tags::Library |
In: |
lib/yard/tags/library.rb
|
Parent: | Object |
Holds all the registered meta tags. If you want to extend YARD and add a new meta tag, you can do it in one of two ways.
Use {Library.define_tag} to define a new tag by passing the tag name and the factory method to use when creating the tag. These definitions will be auto expanded into ruby code similar to what is shown in method 2. If you do not provide a factory method to use, it will default to {DefaultFactory#parse_tag} Example:
define_tag "Parameter", :param, :with_types_and_name define_tag "Author", :author
The first line will expand to the code:
def param_tag(text) tag_factory.parse_tag_with_types_and_name(text) end
The second line will expand to:
def author_tag(text) tag_factory.parse_tag(text) end
Note that tag_factory is the factory object used to parse tags. This value defaults to the {DefaultFactory} class and can be set by changing {Library.default_factory}.
Write your own tagname_tag method that takes the raw text as a parameter. Example:
def mytag_tag(text) # parse your tag contents here end
This will allow you to use @mytag TEXT to add meta data to classes through the docstring. You can use the {Library#factory} object to help parse standard tag syntax.
If you have specialized tag parsing needs you can substitute the {factory} object with your own by setting {Library.default_factory= Library.default_factory} to a new class with its own parsing methods before running YARD. This is useful if you want to change the syntax of existing tags (@see, @since, etc.)

factory | [RW] | A factory class to handle parsing of tags, defaults to {default_factory} |
labels | [R] | |
transitive_tags | [RW] |
Sets the list of tags that should apply to any children inside the
namespace they are defined in. For instance, a "@since" tag should
apply to all methods inside a module it is defined in. Transitive tags can
be overridden by directly defining a tag on the child object.
@return [Array<Symbol>] a list of transitive tags @since 0.6.0 |
visible_tags | [RW] |
Sets the list of tags to display when rendering templates. The order of
tags in the list is also significant, as it represents the order that tags
are displayed in templates.
You can use the {Array#place} to insert new tags to be displayed in the templates at specific positions: Library.visible_tags.place(:mytag).before(:return) @return [Array<Symbol>] a list of ordered tags @since 0.6.0 |
Replace the factory object responsible for parsing tags by setting this to an object (or class) that responds to parse_TAGNAME methods where TAGNAME is the name of the tag.
You should set this value before performing any source parsing with YARD, otherwise your factory class will not be used.
@example
YARD::Tags::Library.default_factory = MyFactory
@param [Class, Object] factory the factory that parses all tags
@see DefaultFactory
Convenience method to define a new tag using one of {Tag}’s factory methods, or the regular {DefaultFactory#parse_tag} factory method if none is supplied.
@param [to_s] tag the tag name to create @param [to_s, Class<Tag>] meth the {Tag} factory method to call when
creating the tag or the name of the class to directly create a tag for
