YARD-Heuristics YARD-Heuristics heuristically determines types of parameters and return values for YARD documentation that doesn’t explicitly document it. This allows you to write documentation that isn’t adorned with “obvious” types, but still get that information into the output. It also lets you nice-looking references to parameters and have them be marked up appropriately in HTML output. § Heuristics The following sections list the various heuristics that YARD-Heuristics apply for determining types of parameters and return values. Note that for all heuristics, a type will only be added if none already exists. § Parameter Named “other” A parameter named “other” has the same type as the receiver. This turns class Point def ==(other) into class Point # @param [Point] other def ==(other) § Parameter Types Derived by Parameter Name Parameters to a method with names in the following table has the type listed on the same row. | Name | Type | |--------+-----------| | index | [Integer] | | object | [Object] | | range | [Range] | | string | [String] | Thus class Point def x_inside?(range) becomes class Point # @param [Range] range def x_inside?(range) § Block Parameters If the last parameter to a method’s name begins with ‘&’ it has the type [Proc]. class Method def initialize(&block) becomes class Method # @param [Block] block def initialize(&block) § Return Types by Method Name For the return type of a method with less than two ‹@return› tags, the method name is lookup up in the following table and has the type listed on the same row. For the “type” “self or type”, if a ‹@param› tag exists with the name “other”, the type of the receiver is used, otherwise “self” is used. For the “type” “type”, the type of the receiver is used. | Name | Type | |-----------------+----------------| | ‹<<› | self or type | | ‹>>› | self or type | | ‹==› | [Boolean] | | ‹===› | [Boolean] | | ‹=~› | [Boolean] | | ‹<=>› | [Integer, nil] | | ‹+› | type | | ‹-› | type | | ‹*› | type | | ‹/› | type | | each | [self] | | each_with_index | [self] | | hash | [Integer] | | inspect | [String] | | length | [Integer] | | size | [Integer] | | to_s | [String] | | to_str | [String] | Thus class Point def <<(other) becomes class Point # @return [Point] def <<(other) but class List def <<(item) becomes class List # @return [self] def <<(item) § Emphasizing Parameter Names When producing HTML output, any words in all uppercase, with a possible “th” suffix, that is also the name of a parameter, an ‹@option›, or a ‹@yieldparam›, will be downcased and emphasized with a class of “parameter”. In the following example, “OTHER” will be turned into ‹<em class="parameter">other</em>›: class Point # @return True if the receiver’s class and {#x} and {#y} `#==` those of # OTHER def ==(other) § Usage Add ‹--plugin yard-heuristics-1.0› to your YARD command line. If you’re using Inventory-Rake-Tasks-YARD¹, add the following to your Rakefile: Inventory::Rake::Tasks::YARD.new do |t| t.options += %w'--plugin yard-heuristics-1.0' end ¹ See http://disu.se/software/inventory-rake-tasks-yard/ § API There’s really not very much to the YARD-Heuristics API. What you can do is add (or modify) the types of parameters and return types of methods by adding (or modifying) entries in the Hash tables ‹YARDHeuristics::ParamTypes› and ‹YARDHeuristics::ReturnTypes› respectively. That’s about it. § Financing Currently, most of my time is spent at my day job and in my rather busy private life. Please motivate me to spend time on this piece of software by donating some of your money to this project. Yeah, I realize that requesting money to develop software is a bit, well, capitalistic of me. But please realize that I live in a capitalistic society and I need money to have other people give me the things that I need to continue living under the rules of said society. So, if you feel that this piece of software has helped you out enough to warrant a reward, please PayPal a donation to now@disu.se¹. Thanks! Your support won’t go unnoticed! ¹ Send a donation: https://www.paypal.com/cgi-bin/webscr?cmd=_donations&business=now@disu.se&item_name=YARD-Heuristics § Reporting Bugs Please report any bugs that you encounter to the {issue tracker}¹. ¹ See https://github.com/now/yard-heuristics/issues § Authors Nikolai Weibull wrote the code, the tests, and this README. § Licensing YARD-Heuristics is free software: you may redistribute it and/or modify it under the terms of the {GNU Lesser General Public License, version 3}¹ or later², as published by the {Free Software Foundation}³. ¹ See http://disu.se/licenses/lgpl-3.0/ ² See http://gnu.org/licenses/ ³ See http://fsf.org/
