open C# scripts on Linux in native monodevelop

Linux? Did I read it right?

Hell yeah! I have been using Unity on arch linux for some time and there’s a great script available that automates the installation and handles workarounds for errors.

But, I couldn’t get C# autocompletion in any text editor the way I was used to in monodevelop so I wrote the script below that formats parameters (*-csharp.sln, filename.cs, fileline) in a way monodevelop can handle.

Test and let me know how it goes, good luck!

Once you install your Unity on Linux:

  • save this script as unity3d_native_monodevelop.sh
  • this is a bash script, give it execution permission with chmod +x unity3d_native_monodevelop.sh
  • open Unity and go to Edit>Preferences>ExternalEditor and select this script
  • put "$(File)" $(Line) as parameters

That’s it!
