Previously the following error was thrown when passing `$data` over the filesystem file name limit:
```
file_exists(): File name is longer than the maximum allowed path length on this platform
```
Whenever an empty tag was found, everything before it risked
being eaten because I wasn't strict enough about the characters
allowed. Crossing `{` can not be allowed.
Fixes#67
Previous one didn't sufficiently remove double semicolons.
This one should be too eager, but then restore them if they
were valid in a for loop.
Fixes#70
Looks like webkit (especially Safari) doesn't properly handle
0% being 0.
Also had to rewrite some regexes because they should now assume
there may still be a unit.
Fixes issue #60
Previous commit of splitting into 2 regexes made no
sense. It seemed slightly faster in a small file, but
with large input, minification time almost doubled.
"return" looks like it could be a variable of which ['x']
is a key. I've improved the code to also check for keywords.
If whatever preceeds it is one of the keywords, don't convert.
Fixes issue #44
I had to split the action of minification into a separate
method because recursively importing files requires them
to also be minified, and I don't want that one to write
to a file.
I assumed it would be able to access the protected property
because we're in one from the same class, so it know the
business logic.
But we're in a closure which, in PHP5.3, doesn't inherit that
scope (which was exactly what I wanted to solve)
Let's just pass it the array, since I don't want to go making
that property public.
* Let everything go through move(), even if the file is not being
written elsewhere (it also does some cleanup)
* Reorder minify statements: string/comment parsing should come first
* Update test with url() that makes no sense
* Update same test to escape as intended (double-escape would’ve been needed)
