[bug#39292] [PATCH 10/10] gnu: Add rapid-photo-downloader

[Sebastian Schott]

Hi Chris,

you are right, some libraries I added in native-inputs of 
rapid-photo-downloader cause trouble, e.g., I got "ValueError: Namespace Notify 
not available", when I try to start the program. This is a bit confusing, 
because before committing, I successfully tested this, but maybe I manually 
installed these libraries and therefore had no "clean" testing environment.

Now, I experimented a bit with native-inputs, inputs and propagated-inputs and 
managed to start the program, when I install it with the code at the end of 
this mail (./pre-inst-env guix install rapid-photo-downloader). When I just 
build the program and cd into the store folder to run it, I still got the 
"notify error" (./pre-inst-env guix build rapid-photo-downloader --> cd 
/gnu/store/.../bin --> ./rapid-photo-downloader). This makes sense, because 
without installing the program, also the propagated-inputs are not installed.

What is the recommended way to test a program without interfering with the 
current user profile, but still considering propagated-inputs?

You mentioned inputs are used for libraries required at runtime. Now I wonder, 
why I need to put libnotify, libgudev, usdisks and gexiv2 into the 
propagated-inputs to avoid errors like "ValueError: Namespace Notify not 
available"?


Best,

Sebastian
