Execute commands in the context of an npm package


Warning this is just getting started, but is already somewhat usable.

cd mymodule
npm-exec 'echo $npm_package_name'
# mymodule
cd node_modules/mydependency
npm-exec 'echo $npm_package_name'
# mydependency

Loads the same environment variables that would be present for npm run-script <blah>, but executes arbitrary bash command lines (even on windows! Thanks to bashful).

Allow saving of command lines into package.json automatically (like npm install --save does now). E.g. you might run: npm-exec --save test "mocha tests/*" and after that your npm test command would be all set up.

Your shell will expand environment variables first, so if you want to reference npm package variables in your command line, they need to be wrapped in single quotes.

npm install -g npm-exec

It's really only useful if it's installed globally (boo! hiss!) maybe it will get integrated into npm one day. Follow the issue that prompted me to write this module for more information.
