gulp-sym

Gulp symlink module

Installation

npm install gulp-sym --save-dev {--production}

Usage

Simple example

var symlink = require('gulp-sym')

gulp
	.src('source')
	.pipe(symlink('path/to/link'))
	//note that it'll return source streams not the symlink ones

Advanced example

var symlink = require('gulp-sym')
  , p = require('path')
  , File = require('gulp-util').File

gulp
	.src(['path/**/to/some/dir/', '!path/example/to/some/dir'])
	//source is a vinyl instance
	.pipe(symlink(function(source) {

		//for example link source is my/dest/path/dirname where dirname matches the glob pattern
		return p.join('my/dest/path', source.relative.split(p.sep)[0])

		//you might also return a vinyl instance if you wanted a different cwd
		return new File({cwd: '/home', path: './symlink'})

	}, { force: true })) //use force option to replace existant

Options

force (bool): force overwrite symlink
relative (bool): your link will be relative

/!\ Don't do this ...

If you're working on more than 1 source, use a function or an array to specify the destination path so gulp-sym doesn't override the previous symlink!

Here is a counterexample, dest will be a link to source/path/two and the first one will not have any symlink!

gulp
	.src(['source/path/one', 'source/path/two'])
	.pipe(symlink('dest', {force: true})) //bad shit WILL happen

... but this

That's how it should be:

gulp
	.src(['source/path/one', 'source/path/two'])
	.pipe(symlink(['dest/one', 'dest/two']))

or through a function that'll be called on each source

gulp
	.src(['source/path/one', 'source/path/two'])
	.pipe(symlink(function(source) {
		return p.resolve(source.path, '../../dest', p.basename(source.path))
	})

It's intendend behavior and api will not change for this, I could warn the user in this case - to be discussed.

Why?

I'm aware that there is another symlink module for gulp but as of v0.1.0 it didn't fit my needs and seems to get messy (absolute/relative). In this plugin, paths are always absolute and resolves from the cwd that you might change by passing a vinyl instance to the destination function.

gulp-symlink :

has no force option to replace existing link
uses fs.symlink twice instead of using fs.exists. I'm aware of the nodejs docs specifying that fs.exists is there on an historical purpose only but why shouldn't we use it?
doesn't use the specified type option mentioned in the nodejs docs (windows only)
has no test on symlinking directories (maybe why tests are good to go on windows)
has bad support on multiple sources (at the moment)
