dft instructions file parser
description
this lib/bin project is the official tool to parse, lint and fix .dft files
why
while working in the dft project I realized 2 things:
-
the dft tool itself shouldn't be responsible of parsing the instructions file, but rather the execution itself
-
haven't made a parser yet, so... here's one
