# Change log

## master

## 0.6.0 (2020-04-23)

- Changed the way edge/proposed features are activated. ([@palkan][])

Use `--edge` or `--proposed` flags for `ruby-next nextify` or
`require "ruby-next/language/{edge,proposed}"` in your code.

See more in the [Readme](./README.md#proposed-and-edge-features).

- Updated RuboCop integration. ([@palkan][])

Make sure you use `TargetRubyVersion: next` in your RuboCop configuration.

- Upgraded to `ruby-next-parser` for edge features. ([@palkan][])

It's no longer needed to use Parser gem from Ruby Next package registry.

## 0.5.3 (2020-03-25)

- Enhance logging. ([@palkan][])

Use `RUBY_NEXT_WARN=false` to disable warnings.
Use `RUBY_NEXT_DEBUG=path.rb` to display the transpiler output only for matching files
in the runtime mode.

## 0.5.1 (2020-03-20)

- Add RuboCop integration. ([@palkan][])

Adds support for missing node types and fixes some bugs with 2.7.

## 0.5.0 (2020-03-20)

- Add `rewrite` transpiler mode. ([@palkan][])

Add support for rewriting the source code instead of rebuilding it from scratch to
preserve the original layout and improve the debugging experience.

## 0.4.0 (2020-03-09)

- Optimize pattern matching transpiled code. ([@palkan][])

For array patterns, transpiled code is ~1.5-2x faster than native.
For hash patterns it's about the same.

- Pattern matching is 100% compatible with RubySpec. ([@palkan][])

- Add `Symbol#start_with?/end_with?`. ([@palkan][])

## 0.3.0 (2020-02-14) 💕

- Add `Time#floor` and `Time#ceil`. ([@palkan][])

- Add `UnboundMethod#bind_call`. ([@palkan][])

- Add `String#split` with block. ([@palkan][])

- **Check for _native_ method implementation to activate a refinement.** ([@palkan][])

Add a method refinement to `using RubyNext` even if the backport is present. That
helps to avoid the conflicts with invalid monkey-patches.

- Add `ruby-next core_ext` command. ([@palkan][])

This command allows generating custom core extension files. Meant to be used in
alternative Ruby implementations (mruby, Opal, etc.) not compatible with the `ruby-next-core` gem.

- Add `ruby-next/core_ext`. ([@palkan][])

Now you can use core extensions (monkey-patches) instead of the refinements.

- Check whether pattern matching target respond to `#deconstruct` / `#deconstruct_keys`. ([@palkan][])

- Fix `Struct#deconstruct_keys` to respect passed keys. ([@palkan][])

## 0.2.0 (2020-01-13) 🎄

- Add `Enumerator.produce`. ([@palkan][])

- Add Bootsnap integration. ([@palkan][])

Add `require "ruby-next/language/bootsnap"` after setting up Bootsnap
to transpile the files on load (and cache the resulted iseq via Bootsnap as usually).

- Do not patch `eval` and friends when using runtime mode. ([@palkan][])

Eval support should  be enabled explicitly via the `RubyNext::Language::Eval` refinement, 'cause we cannot handle all the edge cases easily (e.g., the usage caller's binding locals).

- Revoke method reference support. ([@palkan][])

You can still use this feature by enabling it explicitly (see Readme).

- Support in modifier. ([@palkan][])

```ruby
{a: 1, b: 2} in {a:, **}
p a #=> 1
```

## 0.1.0 (2019-11-18)

- Support hash pattern in array and vice versa. ([@palkan][])

- Handle multiple `-e` in `uby-next`. ([@palkan][])

## 0.1.0 (2019-11-16)

- Add pattern matching. ([@palkan][])

- Add numbered parameters. ([@palkan][])

- Add arguments forwarding. ([@palkan][])

- Add `Enumerable#filter_map`. ([@palkan][])

- Add `Enumerable#filter/filter!`. ([@palkan][])

- Add multiple arguments support to `Hash#merge`. ([@palkan][])

- Add `Array#intersection`, `Array#union`, `Array#difference`. ([@palkan][])

- Add `Enumerable#tally`. ([@palkan][])

- Implement gem integration flow. ([@palkan][])

  - Transpile code via `ruby-next nextify`.
  - Setup load path via `RubyNext::Language.setup_gem_load_Path`.

- Add `ruby-next nextify` command. ([@palkan][])

- Add endless Range support. ([@palkan][])

- Add method reference syntax support. ([@palkan][])

- Add `Proc#<<` and `Proc#>>`. ([@palkan][])

- Add `Kernel#then`. ([@palkan][])
