parol_grammars

A collection of working grammars ready to use for the parol parser generator

Set up parol

For instructions on how to setup parol please have a look at the book or the video.

How to test

The easiest way to test one of the given grammars is to let parol generate a project for you

parol new --bin --path <grammar_name>

In the command above please replace the <grammar_name> with the basename of the grammar file you're about to inspect, e.g. if you want to test the regex grammar from rx.par use the following concrete command:

parol new --bin --path rx

Then enter the newly created folder rx and overwrite the existing rx.par by the one from this repository.

Having this done you are ready to compile the crate

cargo build

After this please modify the test.txt file with content that should be parsed, e.g.

(a|b)*abb

and call the parser:

cargo run test.txt
