Instructions on how to open Unity3d scripts in Rider on Ubuntu

README

#Simple instructions for using Unity3d with project rider on Ubuntu

#1. Download and install latest .deb for Unity3d from:
http://forum.unity3d.com/threads/unity-on-linux-release-notes-and-known-issues.350256/

#2. Download and install the Project Rider EAP (not sure if publicly available but you 
can sign up for early access here: https://www.jetbrains.com/rider/

#3. Open the Unity3d (.deb installs the executable at /opt/Unity/Editor/Unity )

#4. Create a Project in Unity

#5. Start rider and open the .sln file for the project you made in Unity3d

#6. Rider should have made a script on your system on the first start to start itself called `rider`, 
it needs to be in your PATH for this to work

#7. Save the rider-for-unity.sh script below. It will act as a bridge between Unity3d and rider 
that reformats the commandline arguments so that rider can understand them 
(you need to save it and make it executable)

#8. In Unity3d, under Edit > Preferences > External tools
a. Select the rider-for-unity script as the External Script Editory
b. Set

"$(File)" $(Line) 

as the External Script Editor Args

#Scripts should now open in unity

rider-for-unity.sh

#!/bin/bash

#Select this script and add 
#"$(FILE)" $(LINE)
#as the argument in unity preferences for the external script editor

#For some reason everything get's passed as one big blob of an argument
#so this will separate it into a FILEname and LINE number
FILE=$(echo $* | sed 's/"\(.*\)" .*/\1/')
LINE=$(echo $* | sed 's/".*" \(.*\)/\1/')

rider -l $LINE $FILE

Is it fine, if I leave this link here?

Just add it to your Unity solution, point to Rider executable and you have the integration. Works everywhere, including Ubuntu.
