The format is based on Keep a Changelog.

[9.1.2] - 2025-07-07

Fixed

• Fixed a possible hang when getting a file list from Sorbet during type loading. (Thanks @apiology and @ojgarcia)

[9.1.1] - 2025-05-28

Fixed

• Replaced YARD @abstract directives, as they now conflict with Sorbet's abstract! directives when using Tapioca

[9.1.0] - 2025-03-03

Added

• Constants can now be generated or parsed with heredoc strings. (Thanks @apiology)

Fixed

• T.proc types with no parameters are now emitted correctly. Previously, they emitted an invalid call to params() - now they emit no usage of params. (Thanks @apiology)

[9.0.0] - 2024-06-04

Changed

• Updated Commander dependency to 5.0, to remove abbrev deprecation warning. As a result, the minimum supported Ruby version is now 3.0.

[8.1.0] - 2023-01-01

Added

• Parsed method definitions can now have a modifier before the def keyword.

Fixed

• Use File#exist? instead of File#exists? in CLI, fixing an exception on Ruby 3.2.0.
• Resolved incorrect code generation for T::Enums with only one variant.

[8.0.0] - 2022-05-10

Changed

• The parser now loads untyped methods named initialize as returning void, rather than untyped. Potentially breaking if you are relying on this behaviour, though Sorbet now considers this an error.

[7.0.0] - 2022-04-18

Added

• #describe now uses a new, clearer format.
• Added #describe_tree, which produces #describe output for a node and all of its children.
• Added #find and #find_all for retrieving a node's children based on criteria.

Changed

• Parlour now uses the new block-based type_member syntax internally. Potentially breaking if you pin an older version of Sorbet which doesn't support this syntax!
• Improved error message when unable to retrieve the file table from Sorbet.
• #inspect and #to_s now call #describe.

Fixed

• Fixed some incorrect YARD documentation tags.

[6.0.1] - 2021-02-28

Changed

• Disabled runtime type checking for TypedObject#name, resulting in a significant decrease in the time taken to run the conflict resolver.

[6.0.0] - 2021-02-28

Changed

• The RBI previously included with the Parlour gem has been removed, as it was causing issues with Sorbet. If you were relying on Parlour's bundled RBI while type-checking your project, you will now need to use the RBI from sorbet-typed or the Parlour repo.
• Namespace#path will now work much more reliably for classes and modules which replace methods from Module and Class, such as #name.

[5.0.0] - 2020-12-26

Added

• Added RBS generation support! This includes:
  • The new RbsGenerator class
  • RbsObject and a set of subclasses representing different RBS components
  • Note: RBS does not yet support Parlour plugins and some other features. Refer to the README for a full breakdown!
• Added the Types module, which is used to describe types agnostic of the underlying type system
  • Added RbiGenerator::Namespace#generalize_from_rbi! to convert RBI string types into Types types
  • Specifying types as strings is still currently supported, but may be phased out in future, and should be avoided in new projects.
• Added conversion from RBI to RBS type trees
• Added a couple of classes to deduplicate functionality between type systems:
  • TypedObject, which RbiObject and RbsObject both inherit from
  • Generator, which RbiGenerator and RbsGenerator both inherit from
• Added RBI type aliases
• Added sealed! for RBI namespaces
• Added abstract! for RBI modules

Changed

• Parlour::RbiGenerator::Options is now Parlour::Options. An alias exists for now, but Parlour::RbiGenerator::Options is deprecated and could be removed in future versions.
• Updated README and gem metadata to refer to Parlour as a type information generator, rather than just an RBI generator

[5.0.0.beta.3] - 2020-09-15

Changed

Added

• Added Types::Type#describe for simple text descriptions of types
• Added Types::Self for RBI's T.self_type or RBS' self

[4.0.1] - 2020-08-05

Fixed

• Fixed duplicate includes and extends.
• Fixed the block return type for #resolve_conflicts not being nilable.

[4.0.0] - 2020-05-23

Added

• Parlour now defaults to loading the current project when running its command line tool, allowing it to be used as a "sig extractor" when run without plugins! Breaking if you invoke Parlour from its command line tool - to revert to the old behaviour of having nothing loaded into the root namespace initially, add parser: false to your .parlour file.
• Generating constants in an eigenclass context (class << self) is now supported.

[3.0.0] - 2020-05-15

Added

• T::Struct classes can now be generated and parsed.
• T::Enum classes can now be parsed.
• Constants are now parsed.
• TypeParser now detects and parses methods which do not have a sig. Potentially breaking if there is a strict set of methods you are expecting Parlour to detect.

Fixed

• "Specialized" classes, such as enums and now structs, have had many erroneous conflicts with standard classes or namespaces fixed.
• Attributes writers and methods with the same name no longer conflict incorrectly.

[2.1.0] - 2020-03-22

Added

• Files can now be excluded from the TypeLoader.

Changed

• A block argument in the definition but not in the signature no longer causes an error in the TypeParser.
• Sorting of namespace children is now a stable sort.

Fixed

• Type parameters are now parsed by the TypeParser.

[2.0.0] - 2020-02-10

Added

• Parlour can now load types back out of RBI files or Ruby source files by parsing them, using the TypeLoader module.
• The sort_namespaces option has been added to RbiGenerator to alphabetically sort all namespace children.
• Added DetachedRbiGenerator, which can be used to create instances of RbiObject which are not bound to a particular set of options. This is used internally for TypeLoader.
• Parlour will now create a polyfill for then on Kernel.
• Added NodePath#sibling.

Changed

• Version restrictions on rainbow and commander have been slightly relaxed.
• The version of sorbet-runtime is now restricted to >= 0.5 after previously being unrestricted.
• Instances of Namespace can now be merged with instances of ClassNamespace or MethodNamespace.
• A method and a namespace can now have the same name without causing a merge conflict.

Fixed

• Parameter names are no longer nilable. Potentially breaking if you were doing something cursed with Parameter names.

[1.0.0] - 2019-11-22

Added

• T::Enum classes have been implemented, and can be generated using #create_enum_class.
• Methods and namespaces can now be made final using the final: keyword argument.
• Type aliases can be created on namespaces using #create_type_alias.
• The .parlour file can now have globs in relative_requires to load many files matching a pattern at once.

Fixed

• Commander is now a gemspec dependency.

[0.8.1] - 2019-09-27

Added

• Running with the PARLOUR_DEBUG environment variable set will now print debug output to the console during conflict resolution.

Fixed

• Performance is now much faster when the conflict resolver needs to resolve a conflict between many identical objects.

[0.8.0] - 2019-09-14

Added

• Methods can now have type parameters specified.

Changed

• Breaking change: The implementation qualifier is no longer genereated. Following Sorbet merging implementation and override into just override, the Method#implementation and Method#override flags will now both generate the override qualifier.
• The Parlour codebase now uses override for both abstract implementation and superclass overriding to conform to this change.

[0.7.0] - 2019-09-11

Added

• The strictness level can now be specified when generating an RBI, using an optional positional argument to RBIGenerator#generate. The default strictness is strong.
• Plugins can specify a strictness level they would prefer by setting Plugin#strictness for themselves. If multiple plugins set conflicting strictnesses, the least strict will be used.
• Attributes can now specified as class attributes by setting Attribute#class_attribute to true. This will wrap them in a class << self block.

Changed

• The sorbet directory is no longer included in the built gem.
• Generated files now end with a new line (\n).

Fixed

• An instance method and a class method with the same name are no longer considered conflicting.
• The signature for the constructor of Attribute previously typed the optional initializer block as taking a Method. This has been corrected to taking an Attribute.

[0.6.1] - 2019-07-29

Changed

• Various areas of the codebase have been made compatible with older Ruby versions.

[0.6.0] - 2019-07-25

Changed

• Breaking change: the name: keyword argument is now positional instead. Instead of create_method(name: 'A', returns: 'String'), use create_method('A', returns: 'String').
• Altered some syntax to improve compatibility with previous Ruby versions. (Full compatibility is still WIP.)

Fixed

• Fixed some Sorbet type signatures.
• Fixed an RSpec warning.

[0.5.2] - 2019-07-24

Added

• Added the Namespace#create_includes and Namespace#create_extends methods to add multiple include and extend calls at once.

Changed

• Signatures for some methods using keyword parameters have been altered such that those keywords are required. Previously, these parameters defaulted to nil, and the Sorbet runtime would fail an assertion if they weren't present.

Fixed

• Fixed some incorrect documentation for the Namespace methods path and create_constant.
• Fixed a Sorbet signature for Method#describe which was causing an exception.

[0.5.1] - 2019-07-21

Added

• Added the Namespace#path method for plugins to use.

[0.5.0] - 2019-07-20

Added

• Added the create_arbitrary method for inserting arbitrary code into the generated RBI file. This is intended for using constructs which Parlour does not yet support.

Changed

• Breaking change: add_constant, add_include and add_extend have been replaced with create_constant, create_include and create_extend.

[0.4.0] - 2019-07-10

Changed

• Breaking change: The Parlour CLI tool no longer takes command-line arguments, and instead uses a .parlour configuration file. See the README!
• RBIs now begin with # typed: strong.
• Plugins now define a stub constructor to avoid an exception if they don't define one.

[0.3.1] - 2019-07-09

Changed

• Multi-line parameter lists no longer have a trailing comma.

[0.3.0] - 2019-07-09

Changed

• Breaking change: all Namespace#create_ methods, and the Parameter constructor, now take entirely keyword arguments. For example, create_method('A', [], 'String') is now written as create_method(name: 'A', returns: 'String').

[0.2.2] - 2019-07-08

Fixed

• Fixed a bug which occasionally caused includes and extends to generate incorrectly.

[0.2.1] - 2019-07-08

Added

• Added the add_comment_to_next_child method to namespaces.

[0.2.0] - 2019-07-07

Added

• Add support for plugins using the parlour command-line tool.
• Comments can now be added using add_comment.
• Attribute readers, writers and accessors can now be created, using the create_attr_... methods.
• All objects are now YARD documented.

Changed

• The RbiObject, which is core to Parlour's internals, is now an abstract class rather than an interface.
• ConflictResolver now recurses to child namespaces.
• create_method now takes an initializer block like other create_ methods.

[0.1.1] - 2019-07-05

Added

• Initial release!

(0.1.0 was a blank gem.)
