I've been trying, through many different ways to install zen coding for aptana.
First i gone to Zen Coding project hosting, on google and found a weird zip, different from what every walkthrough describe. And following multiple walkthroughs, all of them told me to look for the aptana plugin, on zen coding githubs page. After searching for a long time, i found it, dev version. Then added as default project and stuff, but it just doesn't works and it doesn't have the LIB folder, describe in many tutorials.
Then, finally, i tried adding the official Eclipse/Aptana plugin, the weird one. As i didn't know how to install, just tried extracting to aptana plugins folder. Then, it appears on the menu scripts but when i do ctrl+e, it just crashes(the zen coding). It throws an error without many description.
I'm using Aptana studio standalone 2
Go to:
Help -> Install new software
In the "work with" field, type this repo address: http://zen-coding.ru/eclipse/updates/ http://emmet.io/eclipse/updates/
Press "Add...", give it a name and press OK.
Zen coding should appear on the software list, under "uncategorised". You can install it as you'd install any other plugin.
Hope this helps.
Tested & confirmed to be working with:
Fails with Zend Studio 7.2, but I don't know whether it's a rule or just my bad luck.
