How to enable CSV editor?
November 22nd, 2012 at 8:18 am
Mac users should download complete dmg file.

CSV editor appears when you open any CSV file, see q tab switcher (in the bottom) between text and table editors.

I love the Darcula theme! This is now the best looking IDE i know at all.

Ruby and Scala plugins aren’t compatible with this build. I had to downgrade to latest IU-122.X build. Other than that, it looks great!

Same here: this update is not compatible with Scala and, consecutively, Play 2 support is disabled… that’s a real shame, I will have to roll back as well. Btw, will Idea 12 natively support Play 2 - both for Scala and Java - or it will have to rely on plugins? I’m getting constant error warnings with Scala plugin though it is still better than nothing I guess.

UPDATE: I have to correct myself: Scala plugin and Play 2 for Scala work with this release - you just have to manually uninstall previous versions of corresponding plugins and install new ones. But still there are numerous “IDE fatal error” warnings in Scala plugin.

How can I change the heap size for this version? I used to change the memory size in the Info.plist but it seems that the numbers are gone from the file.

In the latest EAP I am having issues where using a shortcut with CTLR + something triggers the action twice. Such as CTRL+V pastes twice. It isn’t just clipboard actions, CTRL + / will comment out two lines. Once this behavior starts its continues consistently until restarting IntelliJ then it will behave for a while.
Ubuntu 12.10 & Oracle JDK 1.7u9.

Perhaps the next build could let us access the menu without starting a project first…
I like to set up my IDE settings before starting a project.

@Cruz
Then do it - no one stops you from clicking on “Settings” button/entry

Guys it feels like you are doing a lot of refactoring and old three years old issues are coming back.

I hope you have auto regression tests and they just they don’t cover all of the functionality otherwise it makes me very anxious.
Personally I use IDEA to gain productivity but sometimes I spend hours to workaround a bug.
