About StringiFor

StringiFor (Strings Fortran Manipulator) is a pure Fortran 2003+ library that provides a powerful, OOP-designed string type as a drop-in replacement for standard Fortran character variables.

Modern Fortran (2003+) improved character handling considerably with allocatable deferred-length character variables, but Fortran still lacks built-in methods for common string operations — uppercase/lowercase conversion, tokenization, path manipulation, number casting, and more. StringiFor fills that gap.
