Multiple Errors

[marcandre]

I find it difficult to know what triggered an error. I understand unparser does not want to depend on locations, but it would be helpful to have a source line...

The following 2 files generate errors:
https://github.com/deep-cover/deep-cover/blob/master/core_gem/spec/char_cover/exception_else.rb
https://github.com/deep-cover/deep-cover/blob/master/core_gem/spec/char_cover/literals.rb

Even if highly unusual, they are valid Ruby code.

@marcandre This issue contains 2 classes: The splat node not dispatching mlhs correctly, that one is fixed.

The other is the dstr issue I discuss in #196

@marcandre There is another class, and its interesting: spec/char_cover/exception_else.rb

contains code like this:

begin
else
end

that when parsed with parser:

bundle exec ruby-parse -e 'begin; else; end'                     <<<
(fragment:0):1:8: error: else without rescue is useless
(fragment:0):1: begin; else; end
(fragment:0):1: 

fails.

I do not think unparser will and should not ever work on code like this, until parser would have a knob to emit an AST for this case.

I'll put that file on the ignore list for the moment.

Absolutely 👍
