I’m hoping to be able to detect which operating system a Grasshopper definition is running on.
I’ve tried using GHpython and code such as:
import System
print System.OperatingSystem.Platform.Info.Name
But no success yet.
Has anyone else been able to detect the OS from inside Grasshopper?
My use case is to be able to concatenate file paths with folder structures separated by \ for Windows or / for MacOS.
You can also use this native Python module:
Ah thanks very much to both of you!
I’ve just switched a definition from Windows to MacOS and my importing file paths are broken.
It would be perfect if your first suggestion, Laurent, worked on MacOS like it does in Windows but unfortunately I get an error:
'System.IO' object has no attribute 'DirectorySeparatorChar'
But the platform.system() function suggested by both of you works!
Also Anders thanks for patiently re-answering this question. I did genuine searches for answers and didn’t come across your previous post answering this question.
As a follow up question to the community:
Does anyone know why
System.IO.DirectorySeparatorChar
exists on Windows but not on MacOS?
You might want to have a look at the native os.path Python module. It has the os.path.join() function, designed for constructing platform agnostic paths.
Woah very interesting!
Thanks Anders.
No worries. Regarding the separator concern, as I recall you can get that using os.path.sep.
Edit: I didn’t fully recall, it’s just os.sep:

Ah thanks for this too. I will test on my Mac when I get home later.
Yup I’m using os.sep and it works.
Regarding your original question, you can get the OS specific information with the platform module.
import platform
print platform.system()
print platform.release()
# Darwin
# 21.6.0
On macOS, it will output Darwin as system, because that’s the underlying Unix base system. I mean, why not point out the best part of a product?
