FortranReader
Introduction
FortranReader.jl provides basic commands to read the 'unformatted' files written by Fortran programs using Julia.
Although not technically portable, most Fortran programs write these files in a predictable way, in 'records'. Each record contains either one or several variables, marked before and after with the length of the variable(s) in bytes. This marker is written as a 4-byte integer.
This package is a simple module to fulfil a narrow purpose and comes without tests or any guarantee of future updates. See the section on alternatives below for better options for new projects.
Installation
julia
julia> import Pkg; Pkg.add(url="https://github.com/anowacki/FortranReader.jl")
Using the package
Three functions are exported:
- read_record
- skip_record
- write_record
Each is passed an IO object and will read, skip or write a single Fortran
record. The user must pass the type of the record and the dimensions of the
array being read/written if not a scalar.
Example
Read a rank-2 array of reals in the fourth record of a Gfortran unformatted
Fortran binary file into data.
The first and second records contains the dimensions of the array and
are read as a scalars, passing no dimensions. We do not need the third
record and so skip over it.
julia
data = open("file") do io
m = read_record(io, Int)
n = read_record(io, Int)
skip_record(io)
read_record(io, Float32, m, n)
end
Alternatives
- FortranFiles.jl is maintained and tested, comes with documentation, and should be used instead of this package for new projects.
