    10 projects | dev.to | 26 Apr 2022
    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.
