2021-05-21test/syntax.rb: fix endless def warning (no assertion).Yukihiro "Matz" Matsumoto
2021-05-18parse.y: allow "command" syntax in endless method definition.Yukihiro "Matz" Matsumoto
This change allows `def hello = puts "Hello"` without parentheses. This syntax has been introduced since Ruby3.1.
2021-05-03symbol.c: remove `Symbol#id2sym`.Yukihiro "Matz" Matsumoto
In the ancient Ruby, symbols are represented by integers. In that era, to get string representation from integers, we used `Integer#id2sym` method. Later, `Symbol` was introduced, and `id2sym` was used for compatibility. Today, no one uses `id2sym` any longer. It is described in ISO 30170:2012 standard but I consider it as a mistake.
2021-04-27array.c: update `Array#shift` to take optional argument; close #5428Yukihiro "Matz" Matsumoto

2021-04-16feat(CI): add the GitHub Super LinterJohn Bampton
The GitHub Super Linter is a more robust and better supported tool than the current GitHub Actions we are using. Running these checks: ERROR_ON_MISSING_EXEC_BIT: true VALIDATE_BASH: true VALIDATE_BASH_EXEC: true VALIDATE_EDITORCONFIG: true VALIDATE_MARKDOWN: true VALIDATE_SHELL_SHFMT: true VALIDATE_YAML: true https://github.com/marketplace/actions/super-linter https://github.com/github/super-linter Added the GitHub Super Linter badge to the README. Also updated the pre-commit framework and added more documentation on pre-commit. Added one more pre-commit check: check-executables-have-shebangs Added one extra check for merge conflicts to our GitHub Actions. EditorConfig and Markdown linting. Minor grammar and spelling fixes. Update linter.yml

It used to be return the default value if available, but it should ignore the default value for behavior consistency. CRuby will adopt this behavior too in the future. [ruby-bugs:16908]

2020-11-10Reduce memory usage of Hash objectKOBAYASHI Shuji
## Implementation Summary * Change entry list from segmented list to flat array. * Change value of hash bucket from pointer to entry to index of entry list, and represent it by variable length bits according to capacity of hash buckets. * Store management information about entry list and hash table to `struct RHash` as much as possible. ## Benchmark Summary Only the results of typical situations on 64-bit Word-boxing are present here. For more detailed information, including consideration, see below (although most of the body is written in Japanese). * https://shuujii.github.io/mruby-hash-benchmark ### Memory Usage Lower value is better. | Hash Size | Baseline | New | Factor | |----------:|--------------:|--------------:|-----------:| | 16 | 344B | 256B | 0.74419x | | 40 | 1,464B | 840B | 0.57377x | | 200 | 8,056B | 3,784B | 0.46971x | | 500 | 17,169B | 9,944B | 0.57949x | ### Performance Higher value is better. #### `mrb_hash_set` | Hash Size | Baseline | New | Factor | |----------:|--------------:|--------------:|-----------:| | 16 | 1.41847M i/s | 1.36004M i/s | 0.95881x | | 40 | 0.39224M i/s | 0.31888M i/s | 0.81296x | | 200 | 0.03780M i/s | 0.04290M i/s | 1.13494x | | 500 | 0.01225M i/s | 0.01314M i/s | 1.07275x | #### `mrb_hash_get` | Hash Size | Baseline | New | Factor | |----------:|--------------:|--------------:|-----------:| | 16 | 26.05920M i/s | 30.19543M i/s | 1.15872x | | 40 | 44.26420M i/s | 32.75781M i/s | 0.74005x | | 200 | 44.55171M i/s | 31.56926M i/s | 0.70860x | | 500 | 39.19250M i/s | 29.73806M i/s | 0.75877x | #### `mrb_hash_each` | Hash Size | Baseline | New | Factor | |----------:|--------------:|--------------:|-----------:| | 16 | 25.11964M i/s | 30.34167M i/s | 1.20789x | | 40 | 11.74253M i/s | 13.25539M i/s | 1.12884x | | 200 | 2.01133M i/s | 2.97214M i/s | 1.47770x | | 500 | 0.87411M i/s | 1.21178M i/s | 1.38631x | #### `Hash#[]=` | Hash Size | Baseline | New | Factor | |----------:|--------------:|--------------:|-----------:| | 16 | 0.50095M i/s | 0.56490M i/s | 1.12764x | | 40 | 0.19132M i/s | 0.18392M i/s | 0.96129x | | 200 | 0.03624M i/s | 0.03256M i/s | 0.89860x | | 500 | 0.01527M i/s | 0.01236M i/s | 0.80935x | #### `Hash#[]` | Hash Size | Baseline | New | Factor | |----------:|--------------:|--------------:|-----------:| | 16 | 11.53211M i/s | 12.78806M i/s | 1.10891x | | 40 | 15.26920M i/s | 13.37529M i/s | 0.87596x | | 200 | 15.28550M i/s | 13.36410M i/s | 0.87430x | | 500 | 14.57695M i/s | 12.75388M i/s | 0.87494x | #### `Hash#each` | Hash Size | Baseline | New | Factor | |----------:|--------------:|--------------:|-----------:| | 16 | 0.30462M i/s | 0.27080M i/s | 0.88898x | | 40 | 0.12912M i/s | 0.11704M i/s | 0.90642x | | 200 | 0.02638M i/s | 0.02402M i/s | 0.91071x | | 500 | 0.01066M i/s | 0.00959M i/s | 0.89953x | #### `Hash#delete` | Hash Size | Baseline | New | Factor | |----------:|--------------:|--------------:|-----------:| | 16 | 7.84167M i/s | 6.96419M i/s | 0.88810x | | 40 | 6.91292M i/s | 7.41427M i/s | 1.07252x | | 200 | 3.75952M i/s | 7.32080M i/s | 1.94727x | | 500 | 2.10754M i/s | 7.05963M i/s | 3.34970x | #### `Hash#shift` | Hash Size | Baseline | New | Factor | |----------:|--------------:|--------------:|-----------:| | 16 | 14.66444M i/s | 13.18876M i/s | 0.89937x | | 40 | 11.95124M i/s | 11.10420M i/s | 0.92913x | | 200 | 5.53681M i/s | 7.88155M i/s | 1.42348x | | 500 | 2.96728M i/s | 5.40405M i/s | 1.82121x | #### `Hash#dup` | Hash Size | Baseline | New | Factor | |----------:|--------------:|--------------:|-----------:| | 16 | 0.15063M i/s | 5.37889M i/s | 35.71024x | | 40 | 0.06515M i/s | 3.38196M i/s | 51.91279x | | 200 | 0.01359M i/s | 1.46538M i/s | 107.84056x | | 500 | 0.00559M i/s | 0.75411M i/s | 134.88057x | ### Binary Size Lower value is better. | File | Baseline | New | Factor | |:-----------|--------------:|--------------:|----------:| | mruby | 730,408B | 734,176B | 1.00519x | | libmruby.a | 1,068,134B | 1,072,846B | 1.00441x | ##

2020-11-02Replace `R-assignment` by `single-line pattern matching`.Yukihiro "Matz" Matsumoto
Since `R-assignment` in CRuby is abandoned. Single-line pattern matching in `mruby` only matches single local variable at the moment. Currently it works as a right assignment to a local variable. It will be enhanced in the future.

2020-10-12Always add trailing `.0` in `Float#inspect`; ref #4225KOBAYASHI Shuji
Trailing `.0` is removed from `Float#to_s` and `Float#inspect` at 9d08025b. However, I think the more human-readable format is better for `Float#inspect`. For example, in the `Float#to_s` format, the failure message is not well understood when testing values including types by `eql?` (e.g. `Numeric#step` test). ```ruby assert "example" do exp = 1.0 act = 1 assert_operator(exp, :eql?, act) #=> Expected 1 to be eql? 1. end ```
