A small Racket library to detect the OS the program is currently running on.
Looks at /etc/os-release to identify the operating system. In the Racket standard library there is system-type which can tell you all kinds of interesting things about your environment and runtime, but it doesn't tell you on which Linux you're running. This library provides detect-os-release which will return the string debian if your running on Debian and so forth. This code depends on /etc/os-release existing. You can rely on this file existing on any system that runs systemd. For more information about os-release see here or here.
Install the library by running
raco pkg install https://github.com/vdloo/detect-os-release.git
Or by adding it to the deps of your info.rkt file before running raco pkg update --update-deps:
(define deps '("base"
"https://github.com/vdloo/detect-os-release.git"))
Then in your program:
; import the library
(require detect-os-release)
; use the function
(detect-os)
"debian" ; output
To run the unit tests for detect-os-release run:
make test
