2018-01-19parse.y: Remove unneeded type decls for Rippermame
I think that they are not used. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61964 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-01-19parse.y: swap `foo!` and `foo` in Ripper DSLmame
`foo!(...)` means Ripper event, and `foo(...)` means C function/macro call. This is for fail-safe; if I forget `!` accidentally, it would fail to compile, instead of wrongly adding a new Ripper event. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61962 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-01-19parse.y: assign to $$nobu
* parse.y (command): assign to $$. should not rely upon undocumented behavior. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61960 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-01-19parse.y: Allows Ripper DSL to embed C function calls as `foo!`mame
Instead of `_foo`. This makes it useful to do word boundary search of the editor. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61957 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-01-19ext/ripper: Introduce a simple DSL for ripper.y code generationmame
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: $$ = dispatch2(stmts_add, dispatch0(stmts_new), dispatch0(void_stmt)); git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61952 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-01-19parse.y: Fix excessed_comma eventmame
I believe that the assignment to `$$` was just forgotten. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61951 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-01-18parse.y: no longer undef assignablenobu
* parse.y (assignable): no longer needs to undef since r61899. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61901 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-01-18parse.y: REQUIRED_KEYWORDnobu
* parse.y (REQUIRED_KEYWORD): special argument for required keyword argument, for core and ripper. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61899 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-01-16parse.y: simplified compstmtnobu
* parse.y (top_compstmt, compstmt): unified void_stmts with ripper. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61872 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-01-16node.c: Stop double meaning of NODE_FOR by introducing NODE_FOR_MASGNmame
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

git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61863 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-01-16parse.y (new_regexp): Fix SEGV of `/#{"\u3042"}#{'い'}/` in non UTF-8mame
Mixing other encoding string literals in one Regexp caused SEGV. This bug was found by CoverityScan. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61862 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-01-16parse.y (symbol_append): Added to factor out `%i[]` and `%I[]`mame

2018-01-15parse.y (new_command_qcall): Receives a block (optional)mame
There were four cases that uses new_command_qcall and then method_add_block. This change factors out the four rules. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61856 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-01-15parse.y: Removes unreachable warningsmame
tIDENTIFIER is now always a local id (except fname). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61850 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-01-15parse.y: Removes unneeded NULL checksmame
Nowadays, there are less rules whose return value is NULL. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61849 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-01-15parse.y: Remove unneeded NULL checkmame
There are many usages assuming that bodystmt always returns non-null. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61848 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-01-15parse.y (last_arg_append, rest_arg_append): factor out the code clonesmame

2018-01-15parse.y: Remove unused code comment blocksmame
The code fragments were commented out in YARV merge era. I believe that it will be never needed in near future. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61837 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-01-14parse.y: yydebugnobu
* parse.y (yydebug): define to disable a global variable and get rid of linker error when static linked ext. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61822 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-01-14parse.y: Remove unused a macro "FIXME"mame
I don't know what it was, but seems that it has been already fixed since r12117. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61821 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-01-14parse.y: ripper no longer uses rb_discard_nodenobu
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61820 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-01-14parse.y: Remove a code for old yaccmame
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
2018-01-14parse.y: Remove almost all *_gen macros by passing parser_params explicitlymame
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
2018-01-14parse.y: Expand global-like accessor macros for struct parser_paramsmame
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
2018-01-14parse.y: Use "p" for the variable of struct parser_params consistentlymame
