It mentions yacc/lex as bad idea, because they generate code that needs to be compiled again. It is perfectly possible to implement an interpreting parser, which parses some input from a grammar that is specified in some means. (If you have the grammar of the grammar, you could even use it to parse the grammar.) An example of this can be found at: https://github.com/FransFaase/IParse https://github.com/FransFaase/IParse
