Relocation and SDL2

Things have been a little quiet here recently. I am pushing ever westward; this time I moved from sunny Littleton, Colorado, to the equally-sunny Mountain View, California. I’m close enough to Google’s headquarters to be able to see their city-wide free wifi on my laptop, but far enough away that I can’t use it.

Relocation is something of a theme. The little coding time I’ve had has mainly been spent moving repositories from Mercurial/BitBucket to Git/GitHub so that I can hang out with the cool kids. Actually, I’ve been using Git exclusively for about five months and find that, when I do need to use Mercurial, I can’t remember how it works. Within the repositories, I’ve done some relocating too: consolidating DS and SDL code.

SDL2 was released not too long ago and I thought I’d have a play and see if it offered anything new. It seems the most important change for my SDL projects was the inclusion of automatic texture format conversion within the library itself, meaning it has built-in support for converting and displaying bitmaps in ARGB1555 format. This means that all of my DS projects no longer need to keep track of two bitmaps - one in ARGB8888 and one in ARGB1555 format - when in SDL mode.

Upgrading to SDL2 has allowed me to merge the SDL and DS codebases together, meaning I now have a single repository that will build for the DS and OSX out of the box. Getting them to build in Windows and Linux should be trivial. Additionally, the makefiles for the DS versions all work with the latest devkitARM. Something must have changed in the build system as all of the makefiles were broken.

In other news, I’ve been tinkering with Woopsi again. The complex, C#-inspired EventArgs system is out and I replaced it with the set of arguments that are relevant to each event. Gadgets no longer support multiple event handlers; each can now have just a single handler. Much tidier.

Blogging with Mercurial from the Rocky Mountains

It’s been a while since the last update, but I do have a good excuse. I’ve upped sticks and moved from dingy Birmingham, in the UK, to sunny Littleton, Colorado, in the USA.

So, who’s hiring?

I’ve decided to start blogging about those experiences, but rather than flood this blog with personal posts I’m making a separate blog. But what blogging platform to use? It’s not going to have much traffic, I don’t want to put any admin time into it, I don’t want comments or tags or categories. All I want is to be able to post text as quickly as possible using Markdown.

It would be great if there was a blogging platform for Mercurial like the one available to Github users, but I’ve looked around and haven’t been able to find one. So why not write one?

Here’s my list of requirements:

  • Displays blog posts in reverse chronological order (newest first).
  • Posts are written in Markdown and reformatted into HTML automatically.
  • Posts are stored in a repository on BitBucket.
  • Pushing to the posts repository automatically updates the blog.
  • Allows paging through blog posts.
  • Includes an “Archive” page that lists all blog posts.
  • Has an RSS feed.
  • Maintains a cache of blog posts to minimise queries to BitBucket’s API.
  • Looks a bit like WordPress’ “TwentyEleven” theme, as that’s my favourite theme at the moment.

After a couple of evenings of hacking, here’s the result:

And here’s a demo:

A blog powered by BitBucket and Mercurial. Neat!

I’ve included instructions for getting a BitBlogger instance up and running on AppHarbor, a .NET hosting site that offers a basic freemium option. As BitBlogger doesn’t use any local storage or background events (BitBucket notifies it of changes, rather than BitBlogger needing to poll for updates), it doesn’t need anything above the free package.

I’ve copied bits and pieces of the TwentyEleven theme’s CSS file in order to replicate some of the appearance, so the licence for this application is the GPL rather than my preferred MIT licence. If anyone feels like putting together a simple and very legible theme to replace the current look and feel, I’ll be able to switch it over.
