FortranFiles.jl

A Julia package for reading and writing Fortran unformatted (i.e. binary) files.

Features

Currently the following features are implemented and working:

• Sequential Access mode
  • 4-byte record markers, with subrecord support (allowing records larger than 2 GiB)
  • 8-byte record markers (used by early versions of gfortran)
• Direct Access mode
  • fixed-size records without any record markers
• Most standard Fortran datatypes, including arrays and strings
• "Inhomogeneous" records, i.e. records made from multiple different datatypes
• Byte-order conversion (little endian ⟷ big endian)

The following features are not (yet) supported:

• Derived Type I/O
• Equivalents of BACKSPACE and ENDFILE
