    Perhaps, the easiest way to create a lexer for IDEA is to use JFlex. The GrammarKit plugin already contains implementation and allows you to generate a lexer from .bnf file or from .flex file (with more customization options). An example for the Monkey language can be viewed here, a more complex one for Frege - here.

  • Show HN: Yacc/Lex editor/tester online
    3 projects | news.ycombinator.com | 7 Sep 2023
    I'm building an online yacc/lex (LALR(1)) grammar editor/tester to help develop/debug/document grammars, the main repository is here https://github.com/mingodad/parsertl-playground and the online playground with several non trivial examples is here https://mingodad.github.io/parsertl-playground/playground/ .

    Select a grammar/example from "Examples" select box and then click "Parse" to see a parser tree for the source in "Input source" editor.

    It's based on https://github.com/BenHanson/gram_grep and https://github.com/BenHanson/lexertl14 .

    Any feedback is welcome !

    The grammars available so far (with varying state of correctness):
