    Project mention: RCParsing VS ANTLR - a user suggested alternative | libhunt.com/r/RCParsing | 2025-09-19

    ANTLR is a lexer-based, powerful tool for creating own DSL and analyzing them. But it's and overkill for simple languages (JSON, for example), while RCParsing is good for both complex and simple languages, allows you to choose: work with AST or immediately calculate value while parsing.
