This is possible with Sprocket's new <code>stub</code> directive which is available in Sprockets v2.2.0 and up. However, Rails 3.2 will only ever use Sprockets v2.1.3 which does not have this feature. As of now, the current Edge Rails has the <code>stub</code> directive and it will officially be in Rails 4.0 and above.

Usage:

<pre><code>//= require jquery
//= require_tree .
//= stub unwanted_js
</code></pre>

<code>stub</code> directives can not be overridden by subsequent <code>require</code> or <code>include</code> directives.

If you want to use the <code>stub</code> directive in your Rails 3.2 project you will have to switch to Edge Rails, or branch your Rails gem with its Sprockets dependency modified to version 2.2.0.

Since the release of rails 3.2.9, it has support to lock the sprockets to version 2.2.x so that we can use the <code>//= stub</code> directive that latest sprockets have.

NB: This answer is now out of date, with an update to Sprockets having this feature. See the answer below.

===

This is not possible with current Sprockets directives, but it seems like a handy feature.

The other way to to manually list each file you want.

Perhaps you could file this as a feature request over on the <a href="https://github.com/sstephenson/sprockets" rel="nofollow">Sprockets</a> repo? :-)

The following monkey patch solves this for me:

<pre><code>
module Sprockets
 class DirectiveProcessor
 # support for: require_tree . exclude: "", "some_other"
 def process_require_tree_directive(path = ".", *args)
 if relative?(path)
 root = pathname.dirname.join(path).expand_path

 unless (stats = stat(root)) && stats.directory?
 raise ArgumentError, "require_tree argument must be a directory"
 end

 exclude = args.shift == 'exclude:' ? args.map {|arg| arg.sub(/,$/, '')} : []

 context.depend_on(root)

 each_entry(root) do |pathname|
 if pathname.to_s == self.file or exclude.include?(pathname.basename(pathname.extname).to_s)
 next
 elsif stat(pathname).directory?
 context.depend_on(pathname)
 elsif context.asset_requirable?(pathname)
 context.require_asset(pathname)
 end
 end
 else
 # The path must be relative and start with a `./`.
 raise ArgumentError, "require_tree argument must be a relative path"
 end
 end
 end

end
</code></pre>

Try better the <a href="https://github.com/QubitProducts/miniMerge" rel="nofollow">https://github.com/QubitProducts/miniMerge</a>

It supports not only JS and is in basic mode sprockets compatible.

You can exclude not only on file levels but block or even lines.

Full depenedncies managment with multiple source bases.

I used sprockets in past and this one is better, I use it also for CSS.

If I'm using <code>//=require_tree .</code> in application.css, is there a way to exclude particular files other than resorting to <code>//=require_directory</code> and tree organization?

Perhaps something like <code>//= require_tree ., {except: 'something'}</code>

Rails 3.1 Sprockets require directives - is there a way to exclude particular files?
