Parser

A parser turns its input (often text in form of a file) into a more advantageous representation (usually a certain data structure in memory) to perform a specific task.

Common examples include:

https://github.com/taskade/temporal-parser

A lexer and parser for ISO 8601, RFC 3339, and IXDTF temporal expressions, built with compiler design principles.
