Feature req: Logfile

[uhbiv]

Could this generate a logfile, or a comment (special comments if needed) logging the replacements it has made? I noticed that some of my files end up shorter than the original, and wanted a way to track what was pulled out. (and vice versa)

BTW, Autoprefixer remove outdated prefixes, so output CSS may be shorter.

Thanks, it's a good idea. Now grunt-autoprefixer can create patch files like this one:

Index: tmp/diff.css
===================================================================
--- tmp/diff.css
+++ tmp/diff.css
@@ -1,3 +1,6 @@
 .test {
+  background: -webkit-linear-gradient(#000, #111);
+  background: -moz-linear-gradient(#000, #111);
+  background: -o-linear-gradient(#000, #111);
+  background: linear-gradient(#000, #111);
+}
\ No newline at end of file
-    background: linear-gradient(#000, #111);
-}

There is a new option described in README.

thanks @nDmitry .. this was very quick

the patch file reads a bit strange - many +/- for styles that didn't get replaced (or don't need to be logged) hope that can improve in the future. cheers!

@uhbiv it's a different indentation level.
