Team Colorblind's Unity solution editor script

gistfile1.txt

/*

v2: Matt Rix pointed out there's an undocumented ONGeneratedCSProjectFiles() callback
https://gist.github.com/MattRix/0bf8de88e16e8b494dbb

v1: Still available in the gist history if you want a FileSystemWatcher solution!

THE PROBLEM:

- Unity constantly rewrites its .sln files whenever you rename/add/remove scripts
- Their solution files includes a bunch of formatting/tab/etc settings
- Unfortunately, MonoDevelop / Xamarin Studio give these settings priority over your other defaults

(At least sometimes--over here I only get issues maybe once or twice a day)

THE SOLUTION:

- Strip out this entire block of settings whenever any .sln file changes

TO USE:

- Toss this script anywhere in an Editor/ folder
- Enjoy your tabs not getting constantly mangled!

Enjoy,
Matthew / Team Colorblind
