Support for devDependency install

[blaineadams]

When using gulp-param installed as a devDependency only the ouput is always undefined.

For example.

npm install gulp gulp-param --save-dev

There is no global installation of gulp or gulp-param on my system. They are install as dev dependency in the project only.

Create a npm script in package.json called gulp that runs Gulp.

"gulp": "gulp"

Using the sample gulp tasks in the readme

var gulp = require('gulp-param')(require('gulp'), process.argv);

gulp.task('dep', function(debug) {
  console.log(debug); // => true
});

gulp.task('build',  function(debug, tag) {
  console.log(debug); // => true
  console.log(tag); // => 'v1.0.0'
});

Output is:

$ npm run gulp build --debug --tag v1.0.0

> testproj@0.0.0 gulp C:\Development\projects\testproj
> gulp "build"

When Gulp is installed as a devDependency only and run from a npm script, such as npm run gulp as shown above, process.argv cannot capture all the parts. In the example above process.argv only has 3 items in the array.

• path to node
• path to project install of gulp
• task name
