We already have it: https://github.com/symfony/symfony/blob/master/src/Symfony/Component/ClassLoader/ClassMapGenerator.php

this is a Symfony2 CLI command that uses the ClassMapGenerator

Ah sorry, this is the command. Looked at it too fast

Do I understand it correctly that this one allows generating autoloader classmaps for various third-party deps without proper autoloaders?

yes .. thats the idea

Very cool!

@lsmith77 I wonder if we can work more methods on the ClassMapper class in order to include also files that do not contain classes but functions, I have seen that occurring on say zetacomponents. If this generator not only generates a class map but a class map and the set_include_path to include these functions files that would rock? @stof?

@cordoval functions are not autoloadable. So this would be totally useless: you have to require the file before using the function, you cannot ask an autoloader to do the job. And set_include_path would not make functions autoloadable.

I don't think @cordoval was implying that they would be autoloadable .. just that it could collect all files that contain functions and put requires for these files into a single file, to make it easier to manually load all functions of a lib.

the class map generator is not about putting files together but about creating a class map for the autoloader

I don't think that such a command is really useful as you probably want files from more than one directory (and probably exclude some files from these directories). I think it would be much better to write a cookbook in the documentation explaining how to take advantage of the new map generator instead (see symfony/symfony-docs#1134).

it could be a micro command, as this can be fed with a specific folder so to group things, then the cookbook

I volunteer for the cookbook though i don't have a super realistic case yet
