Prevent grunt plugins from overwriting existing files.

Why

When you have a large project or a complex build you might want to make sure that you don't write the same file twice.

How to use

In your Gruntfile.js

var prevent = require("./index.js");

module.exports = function(grunt) {
	grunt.initConfig({
		// Whatever config here
	});

	prevent(grunt);

	grunt.registerTask("default", ["one", "two", "..."]);
};

If any of your grunt plugins is trying to overwrite a file, the task will fail.

You can let the task continue using grunt --force. This will log an error when your tasks try to overwrite a file, but will not change the file content.

Using --force affects all tasks. If you only want to prevent your tasks from failing you can use

var prevent = require("./index.js");

module.exports = function(grunt) {
	prevent(grunt).nofail();
};

Internal details

This plugin is very simple, you can check the code. It overrides the grunt.file.write method to check whether the file already exists.

It only works with other plugins that use grunt.file.write, any call to a write method of node fs module will not be detected.
