* Refactor IRB color dispatchTakashi Kokubun2019-05-261-29/+31
| | | | | | | | | | | | | | | The reason why we were checking lexer state in addition to token was that we do not want to colorize local variable, method call, etc., while they share the :on_ident token with a name of method definition which should be colored as blue. It means that we're concerned about the lexer state only for :on_ident. Thus we can skip checking lexer state for non-:on_ident tokens. This refactoring is based on that idea. Also, now we manage Ripper's lexer state as Integer (use `|` if you need to check multiple states). It should be faster than using Array of Integer because #any? block call is not needed.

* Always color Symbol as Yellow on IRB::ColorTakashi Kokubun2019-05-251-4/+51
| | | | | | | | | | | | | | | | | | | Symbol color was made blue as a workaround because it was hard to distinguish `foo`s in `:foo` and `def foo; end` (both are :on_ident). But I wanted to make it yellow like pry. `:Struct` had the same problem in :on_const. Because the :on_const was also blue (but underlined and bold), it was not a big issue. While they're not so problematic since we got a workaround, we also had a more serious issue for highlighting a symbol like `:"a#{b}c"`. The first half was considered as Symbol and the last half was considered as String, because the colorizer did not have a state like a parser. To approach the last issue, I introduced `IRB::Color::SymbolState` which is a thin state manager knowing only "the token is Symbol or not". Having this module magically solves the first two problems as well. So now we can highlight Symbol as yellow in the perfect manner.
