Prototyping Rust Code in CodeRunner

CodeRunner is a nifty little app for OSX that allows you to play around with test code with minimal fuss. Here are some instructions for setting it up to build Rust code.

Setup instructions

1. Go to CodeRunner > Preferences...
2. Select the Languages tab
3. Down the bottom of the list view, click the plus sign to add a new language called Rust
4. Enable the Language uses compilation script checkbox, and click Edit script
5. Copy the following code into compile.sh:

#!/bin/bash

compname=`echo "$1" | sed 's/\(.*\)\..*/\1/'`
rustc $3 "$1" -o "$compname"
status=$?
if [ $status -eq 0 ]; then
    echo $compname
    exit 0
elif [ $status -eq 127 ]; then
    echo -e "\nTo run code in this language, you need to install the Rust compiler from https://github.com/mozilla/rust/."
fi
exit $status

6. In the Run Command textbox, enter ./$compiler.
7. Add the following text to the Code Template:

fn main() {
    %@
}

8. Set the Syntax Mode to None
9. Enter rs for the File Extension

In CodeRunner 2, the names of the arguments have changed, so the code needs to be updated slightly. I've verified that a simple "Hello, World" program will compile and run in CodeRunner 2 by changing:
$1 to $CR_FILENAME
$3 to $@

So your compile.sh should look like this:

#!/bin/bash

compname=`echo "$CR_FILENAME" | sed 's/\(.*\)\..*/\1/'`
rustc $@ "$CR_FILENAME" -o "$compname"
status=$?
if [ $status -eq 0 ]; then
    echo $compname
    exit 0
elif [ $status -eq 127 ]; then
    echo -e "\nTo run code in this language, you need to install the Rust compiler from https://github.com/mozilla/rust/."
fi
exit $status
