The author of ANTLR, Terence Parr, is a professor at the University of San Francisco and is the inventor of the LL(*) parsing strategy.
This might make you think that ANTLR rests on the same academic foundations as many other tools created in universities and given scary names like “LL(*) Parsing Strategy.” Not true.
From “The Definitive ANTLR Reference”:
In particular, Part III provides the only thorough explanation available anywhere of ANTLR’s LL(*) parsing strategy.
Read: There are few academic publications on ANTLR and seemingly none on its underlying technology.
This isn’t normally a problem. Most useful software is not built on academic foundations. However, ANTLR is positioned more than most to look “academic”. It’s not.
