The PSFWrite.jl module provides a pure-Julia .psf writer.
Let us consider the case of writing time-domain data to a file. The following lines be used to generate results of a "simulation" performed at a frequency of freq = 1e9:
t = collect(0:.01e-9:10e-9) #collect(): API does not yet work with Julia ranges.
y1 = sin.(t*(2pi*freq))
y2 = cos.(t*(2pi*freq))
One would then assemble this data into a PSFWrite.dataset structure, after which everything can be written to file:
using PSFWrite
#Collect data in a special "dataset" structure:
data = PSFWrite.dataset(t, "time") #Init with "x-axis" data (independent variable)
push!(data, y1, "y1") #Add "simulation" results
push!(data, y2, "y2") #Add more "simulation" results
#Write out data to file:
PSFWrite._open("outputfile.psf") do writer
write(writer, data)
end
Please note that the _open-do syntax shown above will automatically call the close() function for the PSFWriter object named writer.

PSFWrite.jl was mostly validated against LibPSF.jl: the pure-Julia implementation of Henrik Johansson's libpsf library. It might not be fully compliant with the PSF format.
PSFWrite.jl does not currently support all .psf file capabilities.
- Only supports writing swept data in a windowed format.
Extensive compatibility testing of PSFWrite.jl has not been performed. The module has been tested using the following environment(s):
- Linux / Julia-1.1.1 (64-bit) / Ubuntu
