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
