Take [the haskell grammar](https://github.com/antlr/grammars-v4/tree/master/haskell), and input [pullTasks.hs](https://github.com/antlr/grammars-v4/blob/master/haskell/examples/pullTasks.hs), then produce a listing of tokens. ``` [@0,0:5='double',,1:0] [@1,6:6=' ',,channel=1,1:6] [@2,7:8='::',,1:7] [@3,9:9=' ',,channel=1,1:9] [@4,10:12='Num',,1:10] [@5,13:13=' ',,channel=1,1:13] [@6,14:14='a',,1:14] [@7,15:15=' ',,channel=1,1:15] [@8,16:17='=>',,1:16] [@9,18:18=' ',,channel=1,1:18] [@10,19:19='a',,1:19]...
This concerns [this code in Java](https://github.com/antlr/grammars-v4/blob/128ebeb55f66061675726ce35e0f47c5c6bfb9d0/php/Java/PhpLexerBase.java#L75) vs [this code in CSharp](https://github.com/antlr/grammars-v4/blob/128ebeb55f66061675726ce35e0f47c5c6bfb9d0/php/CSharp/PhpLexerBase.cs#L83). These codes should not be different, but on sets the token type for the current token, while the other...
There are multiple occurences of actions and predicates such as the following: https://github.com/antlr/grammars-v4/blob/0c9a11ea096dd182862dac03f25766cd5546ff95/php/PhpLexer.g4#L47 https://github.com/antlr/grammars-v4/blob/0c9a11ea096dd182862dac03f25766cd5546ff95/php/PhpLexer.g4#L63 When the Python files are generated, they result in cases such as the following: ``` def...
