ANTLR is a parser generator that uses LL(k) parsing. ANTLR's predecessor is a parser generator known as PCCTS. A compiler-compiler or parser generator is a utility for generating the source code of a parser, interpreter or compiler from an annotated language description in the form of a grammar (usually in BNF) plus code that is associated with each of the rules of the grammar that should be...
An LL parser is a table-based top-down parser for a subset of the context-free grammars. ...

ANTLR stands for "ANother Tool for Language Recognition". Given that ANTLR is in competition with LR parser generators, the alternative reading "ANT(i)-LR" may not be accidental. ANTLR rules are expressed in a format deliberately similar to EBNF instead of the regular expression syntax employed by other parser generators. In computer science, an LR parser is a type of bottom-up parser for context-free grammars that is very commonly used by computer programming language compilers (and other associated tools). ...
The Extended Backus-Naur form (EBNF) is any variation on the basic Backus-Naur form (BNF) metasyntax notation with (some of) the following additional constructs: square brackets [..] surrounding optional items, suffix * for Kleene closure (a sequence of zero or more of an item), suffix + for one or more of an...
A regular expression (abbreviated as regexp or regex, with plural forms regexps, regexes, or regexen) is a string that describes or matches a set of strings, according to certain syntax rules. ...
At the moment, ANTLR supports generating code in the following languages: C++, Java, Python, C#. C++ (generally pronounced see plus plus) is a general-purpose programming language. ...
Java is an object-oriented programming language developed by James Gosling and colleagues at Sun Microsystems in the early 1990s. ...
