About:
Libantlr3c is the official C runtime for ANTLR (ANother Tool for Language Recognition) version 3. It provides the core infrastructure needed to execute parsers and tree walkers generated by the ANTLR tool. This library enables developers to build robust language processors, interpreters, and translators for custom domain-specific languages within C-based applications.

Key Features:

C-based runtime for ANTLR v3 generated parsers
Supports both LL(*) and LL(k) parsing strategies
Integrated with the StringTemplate templating engine for code generation
Generates parse trees and provides tree walking utilities

Use Cases:

Building custom compilers and interpreters for domain-specific languages
Creating parsers for configuration files, log formats, or data serialization languages
Developing static analysis tools and source code transpilers

Alternatives:

libantlr4-runtime – The newer ANTLR 4 runtime features an improved ALL(*) parsing algorithm and simplified API, but libantlr3c is required for legacy v3 grammars.
flex/bison – A classic lexer/parser generator combination; Bison uses LALR(1) which is more performant but less flexible and harder to debug than ANTLR's LL(*).
