[ruby-core:87945] [Feature #14912] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@67586 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-01-20ext/ripper/tools/dsl.rb: Use String#sub instead of delete_suffixmame
It fails when baseruby is old. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61994 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-01-20ext/ripper/tools/dsl.rb: Serialize dispatch callsmame
To avoid the unspecified behavior (the evaluation order of arguments). In `$$ = foo(bar(), baz());`, it is unspecified which `bar` or `baz` is called earlier. This commit changes the code to `v1=bar(); v2=baz(); $$ = foo();`. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61991 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-01-20parse.y: Remove unneeded var_field_1 trickmame
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

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: 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
