Nar created from TypeScript can't reference files in the same folder

[achew22]

Reproduction steps:

cd /tmp
git clone https://github.com/Microsoft/TypeScript.git
cd TypeScript
npm install nar
./node_modules/nar/bin/nar create --executable
mv *.nar /tmp/typescript.nar
cd /tmp
chmod +x typescript.nar
echo "var x = function() {alert('test');}" > /tmp/test.ts

You now have everything the way I would expect it

# This will fail
cd /tmp
/tmp/typescript.nar exec --out test.js test.ts

# This will succeed
cd /tmp
/tmp/typescript.nar exec --out /tmp/test.js /tmp/test.ts

Do you have any ideas on why the cwd is being changed by nar? Is that what it should be doing?

nar executables are extracted into .nar folder by default in the current working directory. I would suggest using absolute paths or change the current directory programmatically as you need it.
