[ruby-core:114604] [Ruby master Bug#19281] SyntaxError if first argument of command call has semicolon inside parenthesis

Issue #19281 has been updated by jeremyevans0 (Jeremy Evans). YARP parses all of these successfully: ```ruby YARP.parse("p (1;2),(3),(4)").success? # => true YARP.parse("p (;),(),()").success? # => true YARP.parse("a.b (1;2),(3),(4)").success? # => true YARP.parse("a.b (;),(),()").success? # => true ``` ---------------------------------------- Bug #19281: SyntaxError if first argument of command call has semicolon inside parenthesis https://bugs.ruby-lang.org/issues/19281#change-104425 * Author: tompng (tomoya ishida) * Status: Open * Priority: Normal * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- These are syntax error ~~~ruby p (1;2),(3),(4) p (;),(),() a.b (1;2),(3),(4) a.b (;),(),() ~~~ I expect it to be syntax ok because the code below is syntax ok. ~~~ruby p (1),(2;3),(4;5) p (),(;),(;) a.b (1),(2;3),(4;5) a.b (),(;),(;) ~~~ It will be easy to traverse sexp if the sexp of first argument is same as others ~~~ruby Ripper.sexp "p (),(),()" # => [:program, [[:command, [:@ident, "p", [1, 0]], [:args_add_block, [[:paren, false], # [:paren, [[:void_stmt]]] [:paren, [[:void_stmt]]], [:paren, [[:void_stmt]]]], false]]]] Ripper.sexp "p (1),(2),(3)" # => [:program, [[:command, [:@ident, "p", [1, 0]], [:args_add_block, [[:paren, [:@int, "1", [1, 3]]], # [:paren, [[:@int, "1", [1, 3]]]] [:paren, [[:@int, "2", [1, 7]]]], [:paren, [[:@int, "3", [1, 11]]]]], false]]]] ~~~ -- https://bugs.ruby-lang.org/
