ST 4U 266: Rewrite Tool Transformations

August 3, 2012 10:52:48.405

Today's Smalltalk 4 You looks at the rewrite tools in VA Smalltalk - they come in as part of the refactoring browser support. If you have trouble viewing it here in the browser, you can also navigate directly to YouTube. To watch now, click on the image below:

Rewrite.

If you have trouble viewing that directly, you can click here to download the video directly. If you need the video in a Windows Media format, then download that here.

You can also watch it on YouTube:


Today we'll look at another one of the interesting tools that comes in with the Mastering ENVY Developer Tools - the rewrite tools (part of the refactoring engine). Specifically, we'll look at code transformation. Using the stock tools, it's easy enough to rename methods, but what if you want to selectively rewrite code within a subset of the applications and classes in the system? On the launcher, open the Rewrite Tool:

Rewrite Tool

To take a simple example, we have a small class in an application that has code like this:


shouldDoThing
	^shouldDoThing isNil
		ifTrue: [shouldDoThing := false]
		ifFalse: [shouldDoThing]

And we would like to change that pattern in this class to:



shouldDoThing
	^shouldDoThing 
		ifNil: [shouldDoThing := false]
		ifNotNil: [shouldDoThing]

Simple enough for one change, but what if there are a number of them in your application - and you don't want to make that change across the entire system?

rewrite

The matching rules above will do what we want - and you can follow that pattern for any such transformation. Next, we'll limit the scope of our change. Click the "Search In" button:

Limit Scope

As we did with Small Lint, select the applications and classes you want to apply the rule to. Then hit the "Ok" Button. You'll see something like the following:

Changes

Nothing has been done yet - the system is showing you the proposed changes. You can either select individual changes to apply, or select "Execute All":

Changes

If the application(s) affected are not open, you'll get prompted by ENVY (as per usual) to create a scratch edition. Once you approve that, you'll be able to open a browser and see the changes above

Need more help? There's a screencast for other topics like this which you may want to watch. Questions? Try the "Chat with James" Google gadget over in the sidebar.

Dawnguard, Mods, and CTD

August 3, 2012 14:26:12.776

A while back, we recorded a podcast on crashing problems related to mods in Skyrim. At the time, it sounded like Michael had run into an edge case that wouldn't impact that many people. Based on what I just ran into, I don't think that's the case anymore. Here's what just happened:

  • I installed Dawnguard via Steam
  • I had to unsubscribe to a number of mods that changed towns and villages, because I was getting a CTD on any exit of an area
  • Things ran fine again, through getting the first Dawnguard quest
  • I went into Dimhollow, and suddenly started getting freezes. A lot.
  • Then the game started CTD every few minutes
  • A look at the logfiles (see this for an explanation on setting that up) showed lots of stack traces, and my save files had suddenly jumped from 13 MB to 50MB

I suspect that most people using the PC game are going to slam headfirst into this, because the intersection of people still playing the game and people using mods is pretty high (especially given how easy it is to install mods with the Steam workshop).

This is utterly game breaking. I now have a level 63 character (with well over 100 hours invested) that is unplayable. Bethesda needs to worry about this, a lot. The game may be slow on the PS3, but it's not completely unplayable.

Letting Things Go?

August 6, 2012 19:42:32.749

I fly a lot these days, commuting to my job site in Dallas - I almost always fly American (since they have a hib in Dallas, it makes it easier to find direct flights). One of the reasons I like American is seatback power - they have it on most of their planes, and at most of the seats on those planes.

However - I think this is one of the things they are allowing to degrade during their time in bankruptcy. I've noticed the power not working in different seats on a number of planes, and this morning (I had the excitement of a 7:05 AM flight), the power was off on one whole side of the plane.

I hope this isn't a sign of them letting other, more important things slide...

Streaming The Future

August 7, 2012 9:42:17.000

Spotted in Planet Squeak

The Altitude web framework has reintroduced work done on a new streams library Xtreams. Traditional Smalltalk-80 streams have served well for decades. Michael Lucas-Smith and Martin Kobetic started Xtreams as an attempt to distill some of their experience into a new implementation of streams. A great video of the 2010 ESUG talk is available here

While Xtreams originated in Cincom Smalltalk, the full codebase is no longer available in the Cincom public repository (you would have to check with Cincom to find out why that is; I have no idea). That means that going forward, Pharo and Squeak are probably your best sources for Xtreams.

Update: Looks like Cincom changed their mind - the code is now in the public store repository
