No, they can't. The special versions of their editors do things that are not possible in a plugin because of how much the UI changes the editor. The good news is that you can now get a license for all of the intellij based IDEs. It's not cheap, but worth it.

That's actually not correct. The functionality of all IDE's we have (with exception of AppCode and CLion) can be obtained via plugins on IntelliJ IDEA. The smaller IDE's are focused around the specific platform / functionality.

Sorry hari, I love intellij and the work you do there, but I do not believe you. Please show me an IntelliJ IDEA that looks and behaves exactly like webstorm and pycharm just with plugins. You can't. For example Pycharm doesn't even have a project settings option. What plugin gives you that?

"Java 8 was SUPPOSED to an even bigger shift than Java 5" No, it's not, Java 8 is mostly lambdas and unlike generics which requires coordinate effort between the client side and the API side, lambdas are just syntactic sugar at client side and plain old interfaces at API side. Because of that, Java 8 is supposed to be a smaller shift than Java 5.

> lambdas are just syntactic sugar at client side No they are not, as they make use of invokedynamic. Certified JVMs must make use of the opcode and not generate anonymous nested classes, as many think they translate to.

But at the library API level it's a much smaller mandatory change.

No, invokedynamic is not mandatory for lambda. It's a proposed translation, which has the advantage to make lambdas that do not capture values to be seen as constant by the VM.

But you're right that certified Java 7 VM must have an invokedynamic opcode.

IntelliJ reminds me of ramp up prior to Firefox 3.5, forever announcing performance increases which never seem tangible. However we're at Firefox 43 now and it seems to have delivered on the 3.5 promises, I still hold out hold for IntelliJ perhaps nearer v20. Damn shame atm though as Cursive Clojure looks awesome.

The Firefox performance increases were (are?) tangible. I don't really remember which version first delivered them, but a long time ago I used Opera (9?) because it was much faster when opening a lot of tabs. Then Firefox became a lot more responsive.

I agree. IdeaVim is the best Vim emulator I've used as well. However, it is still just an emulator and it lacks some Vim features that I use all the time. IdeaVim is very good, but not as good as having NeoVim embedded would be, I think.

I'm curious, what features?

I don't remember all of the issues I had with IdeaVim, but remapping the leader key was one (though I understand this has been fixed), issues with key mapping and the Dvorak keyboard layout, relative line numbering, etc. There were several other issues with key combinations I like using in Vim that didn't work in IdeaVim, but it has been a while and I don't remember what they were.

The Dvorak issue was specific to the JDK on OS X, according to JetBrains. Perhaps this is also fixed, now that they don't require Java 6. I don't know.

Are you asking if IntelliJ IDEA can look like PyCharm? If that's the case, no, it can't. Each IDE is somewhat tailored to the specifics of the framework/language/platform as I mentioned, but the functionality that they provide is available as plugins. For instance with WebStorm you can have node.js, angular.js plugins installed in IntelliJ IDEA and get the same features.

Obviously, IntelliJ IDEA is a polyglot environment so certain things cater to the needs of many platforms and languages, which is why there are some differences in UI, but AFAIK, the core functionality is there.

Having said that, we fully understand that users want to have smaller more focused IDE's based on the specific needs, which is one of the main reasons we started offer the All Products option.

But I do want to stress that the functionality of the different IDE's are via plugins, and that these plugins are available for IntelliJ IDEA, the same day the IDE's are released.

I'm on a ~5 year old Thinkpad (w/ an i5-520m; apparently it benches to roughly the same as the M-5Y31 that's probably in your macbook), but IDEA pins a couple cores on my processor to 100% for half a minute whenever it opens a project and incurs a noticeable delay when tabbing to and from its window. Compared to my work machine, IntelliJ truly crawls. I suppose I'm asking, have you had _any_ responsiveness problems?…

I just timed it, and IntelliJ 15.0.2 took 27 seconds to start up, load a project[1], and finish indexing it. The UI was visible after 17 seconds. As soon as they appeared, UI elements worked fine. I notice no delay or lag when ⌘ + tabbing to IntelliJ. I'd like it if IntelliJ was faster, but I don't have many qualms with the current level of performance. 1.

Well, startup time aside, it seems like increasing the memory has done the trick? Or it may have all been some subjective nonsense to begin with. In any case, it is at least practice at being patient :)

Reminds me of the time I installed Visual Studio 2015. That pig sprayed over 30 GB of files onto my HDD and still needed 3rd party plugins to be on the same level as IntelliJ.

It's amazing how one man's "pig" can be a ton of other people's "best IDE that there is". At least in the case of Visual Studio...I don't hear quite as many people naming IntelliJ as "the best". Not even close.

The only people I hear calling Visual Studio "the best" are usually .NET developers. Considering their lack of choices I'm not surprised.

The IDE itself uses Java 8. You can still work on projects that utilize previous versions of Java.

Just like you could have Java 8 projects before this change.

> Maybe it's Oracle releasing new Java versions every two years now, and being more aggressive about end-of-life'ing the prior versions? This is a big part of it. If you want support for older JDKs, you have to pay Red Hat for OpenJDK support. Which isn't even "real" Java, in the eyes of many companies. Add in the clamour of major libraries and platforms pushing everyone to go to Java 8 so they can slash great chunks…

You can also buy support directly from Oracle: http://www.oracle.com/us/technologies/java/standard-edition/...

From the above site:

* Direct access to secure versions of older releases of Java SE via My Oracle Support

* Rigorous and on-going regression testing and fixes for EOL’d versions of Java SE
