Darting here and there

So another Dart Editor update, now at Build 5104, get it here!. I love how quickly the dart integrated builds have been coming lately. This new version does away with the old 'Libraries' view panel on the left side (by default) and instead implements a Files view. Instead of opening a project you now open the folder containing your project. All of your .dart files are loaded into that. I wasn't sure about it at first, as it is a changes in how it would work previously but already I'm seeing the benefits of it. It does help to encourage a Good folder/subfolder layout, which I was already comfortable with anyways.

I've seen a few people report some difficulties loading their existing projects, however I can't really comment on that as I have not encountered those issues myself. This version did correct the mass of errors I was receiving in the previous version regarding variables hiding other variables or methods. However it did introduce a couple of new ones.

First, this version introduced the changes to the dart:io library, changing all eventHandlers over to be in the form of onEvent, and one-shot methods (such as File.exists) now take the callback function as an argument, as opposed to having to specify an 'existsHandler'. As such I had to go through my code and made updates to the Sockets and Files to properly reflect the changes to the library.

Secondly, I ran into an issue where any print statements, within a class, would generate an error or warning that "print" is not a method in , where ClassName is whatever class happened to contain the print statement. This post in the Dart Group provided an easy, temporary fix, that is to simply import 'dart:builtin' where required. A simple fix and helped to clean up the errors there so I could focus on my own errors that I had to worry about.

I notice that while the IDE and SDK were updated to Build 5104, the Dartium Build remains at 5070. At this time I am still unable to get the Dartium builds to run on my machine due to a version problem with the shared libraries. I receive the following error:

error while loading shared libraries: libgconf-2.so.4: wrong ELF class: ELFCLASS64

I believe this error is related to the fact that I'm running a 64-bit OS, but it's trying to load 32-bit build. This may also have something to do with my early ventures in trying to build DartVM, IDE, and Dartium myself and installing the extra libraries, etc, which may have conflicted with what Dartium is trying to load. In fact, now that I think of it, I should run a good apt-get autoclean and autoremove regardless. I don't believe it will fix it, but certainly clean up my system a little at least. Now I've not been too worried about this as my current project doesn't use or require any client-side work, but eventually it might be interesting to have a working copy of Dartium for when I start working on some client side projects. Hopefully the 64-Bit builds of Dartium will be available by then.
