* parse.y: rewrite excessed_comma processmame2018-01-201-8/+4
| | | | | | | | | | | | | | | | | Currently, parser.y includes core parser and Ripper parser obscurity. In addition, *some* Ripper code uses the result of the core parser, which make it difficult to separate the two parsers. I want to simplify this, not by separating the two parsers, but by making *all* Ripper actions follows the core parser actions. In other words, all the core parser actions run always even in Ripper, and after that, Ripper-specific actions run. For tha sake, in principle, I want to put `/*% ripper: ... %*/` in the end of actions. Anyway, it is too dirty to put it within expressions, IMO. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61990 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* parse.y: Remove unneeded var_field_1 trickmame2018-01-201-10/+10
| | | | | | | | | | | | | | | | | I thought this trick was needed because the result of var_field was passed to different arguments, as follows: ``` $1 = var_field(p, $1); $$ = backref_assign_error(p, $1, $1, &@$); ``` Currently the DSL supports that one result is passed to one argument. However, after the refactoring, I found that `backref_assign_error` uses only one `$1`. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61979 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* ext/ripper: Introduce a simple DSL for ripper.y code generationmame2018-01-191-737/+439
| | | | | | | | | | | | | | | | | | | Currently, parse.y actions are hard to read and write because the code has double meaning (for core parser and for ripper). I think that, if it is easy to write ripper's code shortly and simply, the double meaning trick is not needed. For the sake, this change adds a simple DSL for ripper's code. For example, in parse.y, we can write: /*% ripper: stmts_add(stmts_new, void_stmt) %*/ instead of: $$ = dispatch2(stmts_add, dispatch0(stmts_new), dispatch0(void_stmt)); git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61952 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
