# CHANGELOG ## master ## 2.1.0 (2022-02-02) RBS 2.1 is a release to deliver the types and documents of the new and updated methods of Ruby 3.1. ### Signature updates * Documents imported from Ruby 3.1 ([\#881](https://github.com/ruby/rbs/pull/881)) * Methods/classes updated in Ruby 3.1 ([\#886](https://github.com/ruby/rbs/pull/886)) * io/wait ([\#865](https://github.com/ruby/rbs/pull/865)) * json ([\#863](https://github.com/ruby/rbs/pull/863)) * nkf ([\#873](https://github.com/ruby/rbs/pull/873)) * openssl ([\#866](https://github.com/ruby/rbs/pull/866)) * `Dir.exists?`, `FileTest#exists?` ([\#884](https://github.com/ruby/rbs/pull/884)) * `FileTest` ([\#880](https://github.com/ruby/rbs/pull/880)) * `Gem::Version#<=>` ([\#869](https://github.com/ruby/rbs/pull/869)) * `Process.clock_gettime` ([\#858](https://github.com/ruby/rbs/pull/858)) ### Library changes * Introduce `rbs annotate` command ([\#881](https://github.com/ruby/rbs/pull/881)) * Make prototype rb to be aware of prepend ([\#861](https://github.com/ruby/rbs/pull/861)) * Fixes incorrect "Invalid Variance" error when method type variable shadows outer type variable ([#889](https://github.com/ruby/rbs/pull/889)) ## 2.0.0 (2021-12-24) ### Bounded Generics RBS 2.0 ships with _bounded generics_, which improves the expressiveness of the language by adding a new syntax to define constraints on type parameters. ```rbs class PrettyPrint[T < _Output] interface _Output def <<: (String) -> void end attr_reader output: T def initialize: (T output) -> void end ``` This is the motivating example I found in the [prettyprint library](https://github.com/ruby/prettyprint). The `#initialize` receives a object of type `T` and it must have `#<<` method. This is defined with `< _Output` syntax in the example. It means _`T` has to be compatible with `_Output` interface._ `PrettyPrint[String]` is okay, but `PrettyPrint[Integer]` is a type error. See [the PR for details](https://github.com/ruby/rbs/pull/844). ### RBS Collection manager RBS Collection feature is generally available on RBS 2.0. In short, it is Bundler for RBS. You can manage RBSs of standard libraries and third party gems with `rbs collection` subcommand. ```bash $ rbs collection init created: rbs_collection.yaml # The `install` command set up RBS files and creates `rbs_collection.lock.yaml` file $ rbs collection install Installing actionpack:6.0 (actionpack@ce6664cec73) (...snip...) Using tsort:0 (/path/to/rbs-2.0.0/stdlib/tsort/0) It's done! 21 gems' RBSs now installed. # Now you can use `rbs`, `typeprof` and `steep` commands with the dependencies out of the box! $ rbs validate $ typeprof app.rb $ steep check ``` RBS 2.0 also introduces `manifest.yaml` to declare the dependencies from your gems to standard libraries explicitly. See [the documentation](https://github.com/ruby/rbs/blob/master/docs/collection.md) for more information. ### Breaking changes This version contains a bug fix, which potentially breaks the compatibility with older versions. The super class names in class definitions are now resolved in _outer_ context. It was an incompatibility with Ruby and [this PR](https://github.com/ruby/rbs/pull/856) fixed the problem. ### Signature updates * uri ([\#846](https://github.com/ruby/rbs/pull/846), [\#852](https://github.com/ruby/rbs/pull/852), [\#851](https://github.com/ruby/rbs/pull/851), [\#850](https://github.com/ruby/rbs/pull/850), [#849](https://github.com/ruby/rbs/pull/849)) ### Language updates * Bounded generics ([\#844](https://github.com/ruby/rbs/pull/844)) * Resolve super type names in outer context ([\#856](https://github.com/ruby/rbs/pull/856)) ### Library changes * Add `manifest.yaml` for collection to specify stdlib dependencies ([\#808](https://github.com/ruby/rbs/pull/808)) * Remove experimental warning of `rbs collection` ([\#855](https://github.com/ruby/rbs/pull/855)) * Add the utility `#map_type` methods ([\#841](https://github.com/ruby/rbs/pull/841)) ## 1.8.1 (2021-12-13) ### Library changes * Validate `extend` arguments ([\#840](https://github.com/ruby/rbs/pull/840)) * Allow a relative path as git remote in collection ([\#839](https://github.com/ruby/rbs/pull/839)) ## 1.8.0 (2021-12-02) RBS 1.8.0 ships with a language feature enhancement, _generic type alias_. You can define a type alias with type parameters now. ```rbs type list[T] = [T, list[T]] | nil # Defines a list of type T type int_list = list[Integer] # List of Integer type string_list = list[String] # List of String ``` You can find the detail in the [PR](https://github.com/ruby/rbs/pull/823). ### Signature updates * `Date#+`, `Date#-` ([\#830](https://github.com/ruby/rbs/pull/830)) * `#include?`, `#member?`, `#delete`, `#count` ([\#835](https://github.com/ruby/rbs/pull/835)) ### Language updates * Generic type alias ([\#823](https://github.com/ruby/rbs/pull/823)) ## 1.7.1 (2021-11-18) ### Signature updates * `Thread#value` ([\#824](https://github.com/ruby/rbs/pull/824/files)) ### Library changes * Unquote parameter name ([\#827](https://github.com/ruby/rbs/pull/827)) * Remove `ruby/signature.rb` ([\#825](https://github.com/ruby/rbs/pull/825)) ### Miscellaneous * Use `untyped` as an expectation of return value of `IO#ready?` in test ([\#828](https://github.com/ruby/rbs/pull/828/files)) ## 1.7.0 (2021-11-11) This version replaces `RBS::Parser` implementation from pure Ruby code based on [Racc](https://github.com/ruby/racc) to C extension. It improves the RBS file parsing performance up to 5 times faster. :rocket: * There are some incompatibilities to drop obsolete syntax rules: `super` keyword and `any` type are no longer supported. * [re2c](https://github.com/skvadrik/re2c) is used to generate lexical generator. When you want to change the parser/lexer, change the files under `ext/rbs_extension` directory and run `rake compile` to compile the extension. ### Signature updates * io/console ([\#783](https://github.com/ruby/rbs/pull/783)) * `ENV` -- Note that it introduces a dummy `::ENVClass` class, which is not defined in Ruby. ([\#812](https://github.com/ruby/rbs/pull/812)) * `Net::HTTPRequest` ([\#784](https://github.com/ruby/rbs/pull/784)) * `#clone` ([#811](https://github.com/ruby/rbs/pull/811), [\#813](https://github.com/ruby/rbs/pull/813)) * `Kernel#BigDecimal` ([\#817](https://github.com/ruby/rbs/pull/817)) * `Tempfile.new`, `Tempfile.create` ([\#792](https://github.com/ruby/rbs/pull/792), [\#791](https://github.com/ruby/rbs/pull/791)) ### Library changes * Replace `RBS::Parser` ([#788](https://github.com/ruby/rbs/pull/788), [#789](https://github.com/ruby/rbs/pull/789)) * Fix unexpected `CollectionNotAvailable` without `gems` from git source ([\#795](https://github.com/ruby/rbs/pull/795)) * Print deprecation warning ([\#801](https://github.com/ruby/rbs/pull/801)) * Make `Parser::KEYWORDS` a hash ([\#804](https://github.com/ruby/rbs/pull/804)) * Use _partial clone_ for `rbs collection` installer ([#805](https://github.com/ruby/rbs/pull/805)) * Respect logger level for test/setup logger ([\#819](https://github.com/ruby/rbs/pull/819), [\#822](https://github.com/ruby/rbs/pull/822)) ## Miscellaneous * Avoid a mixture of `Array#filter` and `Array#select` ([\#820](https://github.com/ruby/rbs/pull/820)) * Remove leftover documentation about `super` ([\#807](https://github.com/ruby/rbs/pull/807)) ## 1.6.2 (2021-09-09) ### Signature updates * `Enumerator::Lazy#force` ([\#782](https://github.com/ruby/rbs/pull/782)) * `IO.readlines` ([\#780](https://github.com/ruby/rbs/pull/780)) ### Miscellaneous * Set `$XDG_CACHE_HOME` during test ([\#781](https://github.com/ruby/rbs/pull/781)) ## 1.6.1 (2021-09-05) This is a minor release including test fixes. ### Miscellaneous * Fix stdlib test for `Resolv::Hosts` by removing `/etc/hosts` dependency ([\#779](https://github.com/ruby/rbs/pull/779)) * Fix bundler related test for test-bundled-gems ([\#778](https://github.com/ruby/rbs/pull/778)) ## 1.6.0 (2021-09-05) This release includes a preview of `rbs collection` commands, which is _bundler for RBS_. The command helps you manage RBS files from gem_rbs_collection or other repositories. This feature is a preview, and any feedback is welcome! ### Signature updates * objspace ([\#763](https://github.com/ruby/rbs/pull/763), [\#776](https://github.com/ruby/rbs/pull/776)) * tempfile ([\#767](https://github.com/ruby/rbs/pull/767), [\#775](https://github.com/ruby/rbs/pull/775)) * `IO#set_encoding_by_bom` ([\#106](https://github.com/ruby/rbs/pull/106)) * `OpenSSL::PKey::EC#dh_compute_key` ([\#775](https://github.com/ruby/rbs/pull/775)) ### Library changes * Add `rbs collection` ([\#589](https://github.com/ruby/rbs/pull/589), [\#772](https://github.com/ruby/rbs/pull/772), [\#773](https://github.com/ruby/rbs/pull/773)) ### Miscellaneous * Let `bin/annotate-with-rdoc` process nested constants/classes ([\#766](https://github.com/ruby/rbs/pull/766), [\#768](https://github.com/ruby/rbs/pull/768)) * Stop printing version mismatch message in CI ([\#777](https://github.com/ruby/rbs/pull/777)) * Update Steep and fix type errors ([\#770](https://github.com/ruby/rbs/pull/770), [\#774](https://github.com/ruby/rbs/pull/774)) * Add dependabot configuration ([\#771](https://github.com/ruby/rbs/pull/771)) ##

([#675](https://github.com/ruby/rbs/pull/675)) * Suppress unused variable warning ([#674](https://github.com/ruby/rbs/pull/674)) * Update documents ([#672](https://github.com/ruby/rbs/pull/672)) ## 1.2.0 (2021-04-21) ### Summary RBS 1.2 ships with better support for AST/token locations and `Locator` utility class. The AST objects now keep the locations of tokens. The `Locator` class is to translate the text position (line and column) to semantic object at the location. The class allows to find if a text position is on the class name of a class declaration. ### Signature updates * Hash ([#631](https://github.com/ruby/rbs/pull/631), [#632](https://github.com/ruby/rbs/pull/632), [\#637](https://github.com/ruby/rbs/pull/637), [\#638](https://github.com/ruby/rbs/pull/638), [\#639](https://github.com/ruby/rbs/pull/639), ) * Module ([\#645](https://github.com/ruby/rbs/pull/645)) * Enumerable ([\#647](https://github.com/ruby/rbs/pull/647)) * Array ([\#648](https://github.com/ruby/rbs/pull/648)) * Proc ([\#649](https://github.com/ruby/rbs/pull/649)) * Struct ([\#650](https://github.com/ruby/rbs/pull/650), [\#668](https://github.com/ruby/rbs/pull/668)) * Thread ([\#651](https://github.com/ruby/rbs/pull/651)) * Random ([\#669](https://github.com/ruby/rbs/pull/669)) * Shellwords ([\#665](https://github.com/ruby/rbs/pull/665)) * IO ([\#659](https://github.com/ruby/rbs/pull/659)) ### Language updates * Module self type syntax update ([\#653](https://github.com/ruby/rbs/pull/653)) ### Library changes * Token locations ([\#666](https://github.com/ruby/rbs/pull/666)) * Add RBS::Locator ([\#667](https://github.com/ruby/rbs/pull/667)) * Fix runtime type checker ([\#644](https://github.com/ruby/rbs/pull/644)) ### Miscellaneous * Update documentation for overloading ([\#658](https://github.com/ruby/rbs/pull/658)) * Update target ruby version ([\#633](https://github.com/ruby/rbs/pull/633)) ## 1.1.1 (2021-03-12) ### Signature updates * rubygem ([#630](https://github.com/ruby/rbs/pull/630)) ## 1.1.0 (2021-03-08) ### Summary Errors are now organized by `RBS::BaseError`, `RBS::ParsingError`, `RBS::LoadingError`, and `RBS::DefinitionError`. The library users can rescue RBS related errors with `RBS::BaseError`, parsing errors with `RBS::ParsingError`, and other errors with `RBS::LoadingError` and `RBS::DefinitionErrors`. Updating a part of environments are supported. Library users can remove declarations read from a set of files, adding new declarations, running name resolution related to the new decls, and deleting `DefinitionBuilder` caches related to the changes. See `RBS::Environment#reject`, `RBS::Environment#resolve_type_names`, `RBS::AncestorGraph`, and `RBS::DefinitionBuilder#update`. `RBS::DefinitionBuilder#build_singleton` now returns definitions containing `instance` type, which had returned resolved class instance types. This is a breaking change, but we consider it a bug fix because `RBS::DefinitionBuilder#build_instance` has returned `instance` types and `#build_singleton` has returned `class` type. ### Signature updates * rubygem ([\#605](https://github.com/ruby/rbs/pull/605), [\#610](https://github.com/ruby/rbs/pull/610)) * Array ([\#612](https://github.com/ruby/rbs/pull/612), [\#614](https://github.com/ruby/rbs/pull/614)) * cgi/core ([\#599](https://github.com/ruby/rbs/pull/599)) * Thread ([\#618](https://github.com/ruby/rbs/pull/618)) ### Language updates * Allow trailing comma for Record and Tuple types ([\#606](https://github.com/ruby/rbs/pull/606)) ### Library changes * Allow partial update of RBS declarations ([\#608](https://github.com/ruby/rbs/pull/608), [\#621](https://github.com/ruby/rbs/pull/621)) * Let errors have `TypeName` ([\#611](https://github.com/ruby/rbs/pull/611)) * Add `Parser::LexerError` ([\#615](https://github.com/ruby/rbs/pull/615)) * Performance improvement ([\#617](https://github.com/ruby/rbs/pull/617), [\#620](https://github.com/ruby/rbs/pull/620)) * No substitute `instance` types on `#build_singleton` ([\#619](https://github.com/ruby/rbs/pull/619)) ### Miscellaneous * Make racc name customizable by `RACC` environment variable ([\#602](https://github.com/ruby/rbs/pull/602)) * Suppress warnings ([\#624](https://github.com/ruby/rbs/pull/624)) * Remove needless `Gem::Version` polyfill ([\#622](https://github.com/ruby/rbs/pull/622)) ## 1.0.6 (2021-02-17) * Signature Updates * `Enumerable` ([\#595](https://github.com/ruby/rbs/pull/595), [\#596](https://github.com/ruby/rbs/pull/596), [\#601](https://github.com/ruby/rbs/pull/601)) * `#as_json` ([\#597](https://github.com/ruby/rbs/pull/597)) ##
