| | | | | | | | | NODE_FOR was used both for "for"-statement itself and for multi-assignment of for-statement (for x, y, in...end). This change separates the two purposes, NODE_FOR for the former, and newly introduced NODE_FOR_MASGN for the latter. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61871 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* parse.y: Remove a code for old yaccmame2018-01-141-9/+0
| | | | | | | | The current parse.y won't compile with yacc since it depends on many bison's extensions. Also, configure.ac does not have a check for yacc, so the macro OLD_YACC is no longer used. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61819 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* parse.y: Remove almost all *_gen macros by passing parser_params explicitlymame2018-01-141-717/+635
| | | | | | | | | | | | | In parse.y many functions were suffixed "_gen" and had companion macros to pass struct parser_params implicitly, which made parse.c bigger and more obscure. This change expands and removes almost all "*_gen" macros. This requires explicit passing of struct parser_params, i.e., we need to write "foo(p, ..)" instead of "foo(..)". However, it is just extra three letters. I believe that this is easier to understand. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61818 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* parse.y: Expand global-like accessor macros for struct parser_paramsmame2018-01-141-565/+525
| | | | | | | | For example, `lex_strterm` is expanded to `p->lex.strterm`. I believe that this expansion make the code straightforward. They look not so annoying because "parser" was renamed to "p". git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61817 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* parse.y: Avoid "p" as a variable namemame2018-01-141-104/+104
| | | | | | | | Because I want to use the name "p" for struct parser_params through parse.c. This change renames "p" to "ptr", "paren", etc. depending upon the context. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61815 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* Rename code_range to code_locationmame2018-01-091-352/+352
| | | | | | | | | | | Because the name "code_range" is ambiguous with encoding's. Abbreviations ("crange", and "cr") are also renamed to "loc". The traditional "code_location" (a pair of lineno and column) is renamed to "code_position". Abbreviations are also renamed (first_loc to beg_pos, and last_loc to end_pos). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61721 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
