2024-12-05[ruby/prism] Fix error messages for unterminated ( and {Aaron Patterson
If we hit an EOF token, and the character before the EOF is a newline, we should make EOF token start at the previous newline. That way any errors reported will occur on that line. For example "foo(\n" should report an error on line 1 even though the EOF technically occurs on line 2.

2024-05-23[ruby/prism] Raise `void value expression` in begin clauseseileencodes
In some cases Prism was either not raising an appropriate `void value expression` error, or raising that error when the syntax is considered valid. To fix this Prism needs to check whether we have other clauses on the `begin` rather than just returning `cast->statements`. * If the `cast->statements` are null and the `cast->ensure_clause` is not null, set the code to `cast->ensure_clause` * else * If there is a `cast->rescue_clause` * Check if `cast->statements` are null and `cast->rescue_clause->statements` are null, and return `NULL` * Check if there is an `else_clause`, and set the node to `cast->else_clause`. * Otherwise return `cast->statements` as the node * return `cast->statements` as the node See tests for test cases. Note I took these directly from CRuby so if desired I can delete them since the test will now pass. This only fixes one test in the `test_parse` file, taking failures from 14 to 13. This fixes `TestParse#test_void_value_in_rhs` and is related to issue #2791. https://github.com/ruby/prism/commit/398152b412

2024-03-26[ruby/prism] Fix an incorrect range of `Prism::Location` when ↵Koichi ITO
`PM_ERR_RETURN_INVALID` This PR fixes the following incorrect range of `Prism::Location` when `PM_ERR_RETURN_INVALID`. It may be hard to tell from the text, but this Ruby error highlights `return`: ```console $ ruby -e 'class Foo return end' -e:1: Invalid return in class/module body class Foo return end -e: compile error (SyntaxError) ``` Previously, the error's `Prism::Location` pointed to `end`: ```console $ bundle exec ruby -Ilib -rprism -ve 'p Prism.parse("class Foo return end").errors' ruby 3.3.0 (2023-12-25 revision 5124f9ac75) [x86_64-darwin22] [#<Prism::ParseError @type=:return_invalid @message="invalid `return` in a class or module body" @location=#<Prism::Location @start_offset=17 @length=3 start_line=1> @level=:fatal>] After this fix, it will indicate `return`. ```console $ bundle exec ruby -Ilib -rprism -ve 'p Prism.parse("class Foo return end").errors' ruby 3.3.0 (2023-12-25 revision 5124f9ac75) [x86_64-darwin22] [#<Prism::ParseError @type=:return_invalid @message="invalid `return` in a class or module body" @location=#<Prism::Location @start_offset=10 @length=6 start_line=1> @level=:fatal>] ``` For reference, here are the before and after of `Prism::Translation::Parser`. Before: ```console $ bundle exec ruby -Ilib -rprism -rprism/translation/parser33 -ve 'p Prism::Translation::Parser33.parse("class Foo return end")' ruby 3.3.0 (2023-12-25 revision 5124f9ac75) [x86_64-darwin22] (string):1:18: error: invalid `return` in a class or module body (string):1: class Foo return end (string):1: ^~~ /Users/koic/.rbenv/versions/3.3.0/lib/ruby/gems/3.3.0/gems/parser-3.3.0.5/lib/parser/diagnostic/engine.rb:72:in `process': invalid `return` in a class or module body (Parser::SyntaxError) from /Users/koic/src/github.com/ruby/prism/lib/prism/translation/parser.rb:220:in `block in unwrap' from /Users/koic/src/github.com/ruby/prism/lib/prism/translation/parser.rb:218:in `each' from /Users/koic/src/github.com/ruby/prism/lib/prism/translation/parser.rb:218:in `unwrap' from /Users/koic/src/github.com/ruby/prism/lib/prism/translation/parser.rb:49:in `parse' from /Users/koic/.rbenv/versions/3.3.0/lib/ruby/gems/3.3.0/gems/parser-3.3.0.5/lib/parser/base.rb:33:in `parse' from -e:1:in `<main>' ``` After: ```console $ bundle exec ruby -Ilib -rprism -rprism/translation/parser33 -ve 'p Prism::Translation::Parser33.parse("class Foo return end")' ruby 3.3.0 (2023-12-25 revision 5124f9ac75) [x86_64-darwin22] (string):1:11: error: invalid `return` in a class or module body (string):1: class Foo return end (string):1: ^~~~~~ /Users/koic/.rbenv/versions/3.3.0/lib/ruby/gems/3.3.0/gems/parser-3.3.0.5/lib/parser/diagnostic/engine.rb:72:in `process': invalid `return` in a class or module body (Parser::SyntaxError) from /Users/koic/src/github.com/ruby/prism/lib/prism/translation/parser.rb:220:in `block in unwrap' from /Users/koic/src/github.com/ruby/prism/lib/prism/translation/parser.rb:218:in `each' from /Users/koic/src/github.com/ruby/prism/lib/prism/translation/parser.rb:218:in `unwrap' from /Users/koic/src/github.com/ruby/prism/lib/prism/translation/parser.rb:49:in `parse' from /Users/koic/.rbenv/versions/3.3.0/lib/ruby/gems/3.3.0/gems/parser-3.3.0.5/lib/parser/base.rb:33:in `parse' from -e:1:in `<main>' ``` This PR ensures that the originally intended `return` is highlighted as it should be. https://github.com/ruby/prism/commit/1f9af4d2ad
2024-03-25[ruby/prism] Fix incorrect paring when using invalid regexp optionsKoichi ITO
Fixes https://github.com/ruby/prism/pull/2617. There was an issue with the lexer as follows. The following are valid regexp options: ```console $ bundle exec ruby -Ilib -rprism -ve 'p Prism.lex("/x/io").value.map {|token| token[0].type }' ruby 3.3.0 (2023-12-25 revision https://github.com/ruby/prism/commit/5124f9ac75) [x86_64-darwin22] [:REGEXP_BEGIN, :STRING_CONTENT, :REGEXP_END, :EOF] ``` The following are invalid regexp options. Unnecessary the `IDENTIFIER` token is appearing: ```console $ bundle exec ruby -Ilib -rprism -ve 'p Prism.lex("/x/az").value.map {|token| token[0].type }' ruby 3.3.0 (2023-12-25 revision https://github.com/ruby/prism/commit/5124f9ac75) [x86_64-darwin22] [:REGEXP_BEGIN, :STRING_CONTENT, :REGEXP_END, :IDENTIFIER, :EOF] ``` As a behavior of Ruby, when given `A` to `Z` and `a` to `z`, they act as invalid regexp options. e.g., ```console $ ruby -e '/regexp/az' -e:1: unknown regexp options - az /regexp/az -e: compile error (SyntaxError) ``` Thus, it should probably not be construed as `IDENTIFIER` token. Therefore, `pm_byte_table` has been adapted to accept those invalid regexp option values. Whether it is a valid regexp option or not is checked by `pm_regular_expression_flags_create`. For invalid regexp options, `PM_ERR_REGEXP_UNKNOWN_OPTIONS` is added to diagnostics. https://github.com/ruby/prism/commit/d2a6096fcf
