Accept a Buffer in addition to files in .compile()

[sindresorhus]

I've created a gulp plugin for Closure Compiler using this excellent module.

Gulp works on streams and buffers and not files while this module requires you to supply files. A lot of other Node things does this too.

It would be useful if you could also supply a buffer that is passed to the Closure Compiler stdin.

Like:

ClosureCompiler.compile(new Buffer('function foo() {}'), {}, function () {});

I see. Do you know if closure compiler itself allows compilation of stdin? That'd be required to make something like this work. Everything else would still require a temporary file.

Looks like it https://www.google.no/search?q=closure+compiler+stdin&oq=closure+compiler&aqs=chrome.0.69i59l3j69i57j69i60j69i65.2516j0j7&sourceid=chrome&espv=210&es_sm=91&ie=UTF-8

Would be something like:

closureProcess.stdin.write(new Buffer('test'));

Any update on this?

Bump, I would also really like to use this inside of a Connect pipeline. It's a shame to have to write content to a temporary file ;(

+1 We demand that :-) Should I send PR?

Any update?

It's possible to use buffer for Closure Compiler. But unfortunatelly not like that:

files.map(function(file) {
  var src = file.contents.toString();
  jar.stdin.write(src);
});
jar.stdin.end()

From my experiments it seems that closure_entry_point option does not work with piped files. Especially, compiler seems to not be able to reorder files as needed. This https://code.google.com/p/closure-compiler/wiki/ManageClosureDependencies simply does not work.
But when I use plain old -js parameter, it works.
There is also another issue related to Windows, http://stackoverflow.com/questions/3205027/maximum-length-of-command-line-string
Fortunatelly, compiler supports special flag file.

So I am almost decided to use https://github.com/vesln/temporary, there is no other way.

New gulp-closure-compiler (or another name) will be finished soon.
