Compile script for using .NET Core with CodeRunner <https://coderunnerapp.com>

coderunner_dotnet.sh

#!/bin/bash

# To use CodeRunner with .NET Core on a Mac, do this:
#
# 1. Buy CodeRunner <https://coderunnerapp.com>
# 2. Download and install .NET Core SDK from <https://www.microsoft.com/net/learn/get-started/macos>
# 3. Launch CodeRunner and open its Preferences
# 4. In the Languages pane:
#    - Select the existing "C#" language (which is for Mono), click the
#      gear icon at the bottom of the window and choose Duplicate, then
#      name the new language "C# .NET Core".
#    - Ensure the "Language uses compile script" checkbox is checked,
#      click the "Edit Script" button, and replace the script content
#      with this file.  Save.
#    - In the "Run command" entry field, replace contents with this:
#        dotnet run --no-build --project "$compiler"
#    - Close the Preferences window
# 5. Now you can choose "C# .NET Core" as your language in the upper-left
#    pop-up menu, write some code, and it will be compiled and run
#    using the .NET Core SDK.

# This is a CodeRunner compile script. Compile scripts are used to compile
# code before being run using the run command specified in CodeRunner
# preferences. This script is invoked with the following properties:
#
# Current directory:	The directory of the source file being run
#
# Arguments $1-$n:		User-defined compile flags	
#
# Environment:			$CR_FILENAME	Filename of the source file being run
#						$CR_ENCODING	Encoding code of the source file
#						$CR_TMPDIR		Path of CodeRunner's temporary directory
#
# This script should have the following return values:
# 
# Exit status:			0 on success (CodeRunner will continue and execute run command)
#
# Output (stdout):		On success, one line of text which can be accessed
#						using the $compiler variable in the run command
#
# Output (stderr):		Anything outputted here will be displayed in
#						the CodeRunner console

# HOME isn't available to this script, but dotnet needs it.
