guides development contributing readme md rbs rbs is a language to describe the structure of ruby programs you can write down the definition of a class or module methods defined in the class instance variables and their types and inheritance mix in relations it also allows declaring constants and global variables the following is a small example of rbs for a chat app module chatapp version string class user attr_reader login string attr_reader email string def initialize login string email string void end class bot attr_reader name string attr_reader email string attr_reader owner user def initialize name string owner user void end class message attr_reader id string attr_reader string string attr_reader from user bot means union types from can be user or bot attr_reader reply_to message means optional type reply_to can be nil def initialize from user bot string string void def reply from user bot string string message end class channel attr_reader name string attr_reader messages array message attr_reader users array user attr_reader bots array bot def initialize name string void def each_member user bot void void and means block enumerator user bot void method can be overloaded end end the target version the standard library signatures targets ruby 3 1 the latest release of ruby the library code targets ruby 3 1 3 0 and 2 7 it runs on 2 6 in fact installation install the rbs gem gem install rbs from the command line or add a line in your gemfile gem rbs cli the gem ships with the rbs command line tool to demonstrate what it can do and help develop rbs rbs version rbs list rbs ancestors object rbs methods object rbs method object then library there are two important concepts environment and definition an environment is a dictionary that keeps track of all declarations what is the declaration associated with string class an environment will give you the answer a definition gives you the detail of the class what is the type of the return value of gsub method of the string class the definition for string class knows the list of methods it provides and their types the following is a small code to retrieve the definition of the string gsub method

library signature contribution guide writing signatures guide stdlib signatures guide syntax development after checking out the repo run bin setup to install dependencies then run bundle exec rake test to run the tests you can also run bin console for an interactive prompt that will allow you to experiment to install this gem onto your local machine run bundle exec rake install to release a new version update the version number in version rb and then run bundle exec rake release which will create a git tag for the version push git commits and tags and push the gem file to rubygems org
