How do you specify a dependency on some external program in your package?
I need to read meta data from a variation of video files and I thought I’d use ExifTool (please let me know if there is a julian alternative). Is there a way to tell julia to install that program when a user Pkg.clones my package? Assuming said external program exists on all platforms, will this work regardless of what platform julia is sitting on?
Thanks!
My plotting package Gaston requires gnuplot. What I do is to check for the presence of gnuplot when the package is loaded, and emit an error if it can’t be found. I could have used BinDeps.jl, but I didn’t want to have to deal with the different installation methods across platforms, requiring sudo, etc.
I see. Not sure my users will figure out how to install stuff… But it might be what I’ll fall back onto. Thanks!
BinDeps will run a set of installation instructions, so users don’t have to know how to do it.
Yea, that’s impressive!
