ANTLR (ANother Tool for Language Recognition) is a powerful parser generator for reading, processing, executing, or translating structured text or binary files.
Flex (fast lexical analyzer generator) is a tool for generating scanners. A scanner, sometimes called a tokenizer, is a program which recognizes lexical patterns in text. The flex program reads user-specified input files, or its standard input if no file names are given, for a...
Generates LALR(1), canonical LR(1), or IELR(1) parsers from formal grammar input, detects ambiguities, provides syntax error handling, integrates with existing code, and supports C, C++, or Java code output for compiler development and more.
textX is a meta-language for building Domain-Specific Languages (DSLs) in Python. It is inspired by Xtext.
It will help you build your textual language easily. You can invent your own language or build a support for an existing textual language.
