Once this is released, I will contact JetBrains about it, so they can integrate PHPMD through stdin.

Since PHPMD has kept backwards compat it shouldn't be a problem for almost 100 % of our user base to upgrade to the newest relase containing this feature.

Note that it only provide a shortcut from - to php://stdin but older versions already support it via the long form:

cat src/MyFile.php | ./src/bin/phpmd php://stdin text foo/rules.xml

@kylekatarnls yeah. i'm aware of that. Thanks.

Having both ways will only make it easier for them to integrate PHPMD through stdin.
