Re: question about Antlr parser upgrade

[Christofer Dutz]

Hi all,

let me give some points I know from the past:
- With Anlr4 grammars you seem to be able to express more rules
- Antlr4 parsers appear to be a lot faster than Anltr3 parsers
- Antlr4 grammars are easier to read (at least this is my impression)
- Implementing Parsers/Compilers with an Antlr4 grammar is a lot easier as 
there is no longer a mixture of Antlr3 and Java code (the grammar contains 
absolutely no code and all is implemented by overriding "enterXYZ" and 
"exitXYZ" methods).

So I was happy when reading that you're switching to antlr4.

    Hi,
    
    Let's discuss about PR#336..
    
    1. Which issue the PR is for.
    
    2. As you (@Ring-K) upgrade the parser from antlr 3  to antlr 4, what
    benefit can we get?
    
    Best,
