Module parser 

Fortran source code parsing utilities.

This module provides the infrastructure for reading and tokenizing Fortran source:

• CharFilter: Iterator adapter that identifies strings, comments, and code regions
• InputStream: Joins continuation lines (&) and splits semicolon-separated statements
• patterns: Precompiled regex patterns for Fortran syntax elements

The parser handles Fortran’s line-continuation semantics, string literals (both single and double quoted), and inline comments while preserving the original structure for accurate reformatting.
