Initial goal to writing this plugin - fix the problem with original APT which not works on my version of Eclipse.
So -after short searching for alternative or at least sourcecode for plugin above the WIKI gave me a lot of ideas ... ...and the project is here... ...with unique name.... ...yep.
YEP APT - AlmostPlainText Editor
is an Eclipse plugin
that can be used to edit and preview APT (Almost Plain Text) files.
