Eclipse Papercut #15 – Simplified access to the structured selection of Viewer

Eclipse Mars will make access to the structured selection of a StructuredViewer easier. So instead of:

ISelection selection = combo.getSelection();
IStructuredSelection sel = (IStructuredSelection) selection;

You can write

IStructuredSelection sel = combo.getStructuredSelection();

Not a big one, but one of the little annoying things. See the rest of the Eclipse papercut series

Eclipse now runs on Wayland

Still needs more work.

As the end of GSoC 2014 approaches, I can now say that Eclipse successfully starts in Weston. Some things look a little bit strange and I’m sure there are more bugs to work out, but for now the majority of Eclipse seems to run properly in a Wayland environment.

Eclipse Science

Every programmer knows that the Eclipse Rich Client Platform has been designed to build the popular Java IDE that can be enhanced for many more programming languages and is often used internally in business software to manage customers and products. So it boils down to just integrated development environments and enterprise resource planning. Scientists all over the world discovered: that may not be so true after all!

Eclipse is not a terminal anymore – Default line size of Java code formatter is now 120

Approx. 3 years ago, I opened a bug report to increase the Java code formatter to 120. This is now implemented, and will be the new Eclipse JDT default for Mars.

I think that is a good sign, the Eclipse project is less and less restricted by its past.

Who and how many people contributed to a Git repository during a given period?

For my new book I wanted to check how many people contributed to the platform.ui repository during the last three months:

git log –since=’last 3 month’ –raw | grep “^Author: ” | sort | uniq -c

seem to be doing the job fine.

git log –since=’last 3 month’ –raw | grep “^Author: ” | sort | uniq -c | wc -l

gives a a count for this period.

27 is the answer in case someone else is interested.

Styling of Eclipse table headers (without SWT support)

Just for reference, the PyDev developer Fabio Zadrozny just posted a nice snippet with allows you to style your SWT table headers via CSS (with your register the snippet as CSS property handler).

See the comments in Liclipse released and directly the snippet Gist snippet.

Working with the JNI side of SWT

The JNI (Java Native Interface) is a way to link a Java program, running in the JVM (Java Virtual Machine) with a native program. This can have many uses, one of which is the ability to utilize platform-optimized code in performance critical components of an application. SWT uses this to access platform dependent GUI libraries in a platform independent way. This interface allows a user of SWT to write an application in a standardized, Java-based API, while the resulting product will have the Look and Feel of a native app. Because of this usage, SWT can be conceptually divided into two different sets of code; a standardized, developer-facing Java API, and the native code that makes it work.
