Top 20 Java CPP Projects

  1. ANTLR

    ANTLR (ANother Tool for Language Recognition) is a powerful parser generator for reading, processing, executing, or translating structured text or binary files.

    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.

  6. fory

    A blazingly fast multi-language serialization framework for idiomatic domain objects, schema IDL, and cross-language data exchange.

    Project mention: Extend Protobuf/FlatBuffers Schema IDL with Shared/Circular Reference Support | news.ycombinator.com | 2026-03-11

    If you already have .proto or .fbs schemas and you want shared/circular reference support, with the Fory compiler you can keep those schemas, add a small set of Fory options, then foryc generates idiomatic native models across Fory-supported languages

    With fory first-class object graph serialziation support, you can serialize object graphs without manual *_id link reconstruction or rewriting your entire schema into Fory Schema.
