Use the HTML version. I haven't updated the ANTLR one in a while. 
(You may not have noticed the line in the readme that says "The 
file that you're probably looking for is grammar.html.")

Right now there are four parsers for D:

Mine, which is used by DCD and D-Scanner:
https://github.com/Hackerpilot/Dscanner/blob/master/std/d/

DParser2, which powers Mono-D:
https://github.com/aBothe/D_Parser/tree/master/DParser2/Parser

LibD which is used by SDC:
https://github.com/deadalnix/libd/tree/master/src/d/parser

The DMD front-end which is used by DMD, LDC, and GDC:
