JetBrains IntelliJ IDEA Blog

There are many great programming languages. And today we often pick one that fits best for a particular task. IntelliJ IDEA is a great IDE for polyglot programming offering out-of the box support for many languages plus a variety of language plugins.

Last year we’ve started creating language-specific IDEs such RubyMine for Ruby/Rails and Web IDE for HTML, JavaScript and PHP. Recently we’ve made available public preview of a new specialized IDE built on the IntelliJ platform — JetBrains PyCharm.

PyCharm is the environment for programming using Python and for web-development with Django framework.

Obviously, JetBrains PyCharm inherits all the functionality of the latest IntelliJ IDEA 9.0 for editing HTML, CSS, JavaScript, XML, working with VCS and more.

PyCharm 1.0 will be available later this year.

Download Public preview of PyCharm now to try it.

Read more about JetBrains PyCharm and participate in the Early Access Program.

We are going to continue to develop and release the Python plugin for IntelliJ IDEA. The plugin will remain free for all users of IntelliJ IDEA Ultimate.

Develop with pleasure,
JetBrains Team

Next Maia EAP comes with full support of Maven Properties and Filtered Resources. New features include:

Go to declaration with Ctrl+B on a property from your pom.xml files, settings.xml and profiles.xml files, system and environment properties, and properties defined in custom Maven filters.

Find Usages

Rename properties defined in the section of you Maven project and custom filters files.

Starting next Maia EAP, classpath for Maven-based projects will be built following Maven rules.
Also, IntelliJ IDEA will natively support compile, test and run-time dependency scopes.

For more information see Maven Dependency Mechanism documentation.

Next Maia EAP includes fully integrated Maven 2.2 support:

• Parallel dependency resolution
• Import dependency scope
• And more.

IntelliJ IDEA 9 (Maia) lets you assign custom colors to arbitrary sets of files (Scopes) in Editor tabs or Navigation lists (Go to class/file, etc):


This helps you even more quickly than before understand which class you are looking at: JDK, a library, or your own app. The feature is available in Maia builds that you can get from EAP under Settings/File Colors.

In Maia you can quickly look up a value in a debugger session by hovering your mouse over it (which is very handy for text values, for example):


When you need to browse through a large tree of values, this popup can be set to appear only after you invoke it.


The trick is that it is still viewable, but only when you hover mouse over a value holding the Alt key. Hitting Alt when the popup is open hides it — but that’s what you probably have already guessed.

There is also an option in the Settings dialog:

If you ever tried to understand or edit regular expression like this in JavaScript or ActionScript:

Then you are sure to find IntelliJ IDEA 9 a more helpful in this way. Now you can repeatedly press Ctrl+W to see non-capturing groups:

Plus, code completion after \ is also a bit smarter:

As you may already know, Internet Explorer supports a technique of inserting JavaScript snippets into css expressions. In case you need to edit such code, IntelliJ IDEA 9 will be happy to assist you with completion and highlighting!

We’ve been blogging about the cool new features implemented in the EAP builds of Maia (IntelliJ IDEA 9) for a while, and now at last you can download and try the new build for yourself.

The new features available in the new build include:

• Backgroundable file indexing, limited navigation / editing / VCS functionality during such process.

  • JPA 2.0 (JSR-317)
  • EJB 3.1 (JSR-318)
  • JSF 2.0 (JSR-314)
  • WebBeans (JSR-299)
  • Bean Validation (JSR-303)
• PHP support
• Tapestry support
• OSGI support
• JavaScript debugger via Firefox plugin
• GWT 1.6 support (see IDEADEV-34713 for details)
• Task context management
• Spell checker
• Grails Project View
• SmartType completion after ‘new’ in Groovy
• Closure and generic parameters foldings
• Easy class exclusion from completion & auto-import
• Highlighting of globally unused symbols

We’re eagerly waiting for your feedback on the new build. Feel free to let us know what you think on the forums, and post bugs and feature requests to our issue tracker.

And may you always develop with pleasure!
