[okra-announce] Okra SBCL & CCL executables for Windows released
by Erik Winkels 10 Sep '09

10 Sep '09

I've saved executable images of SBCL and CCL on Windows and they're available as "okra-20090910.zip" from the Okra project page (http://common-lisp.net/project/okra/). This should make it easier for people on Windows to start playing with Okra since it comes with all the necessary libraries. Just double-click okra-sbcl.exe or okra-ccl.exe and you should be looking at a Common Lisp REPL with Okra installed. If you enter: (load "examples/flock") or (okra::okra-window) You should end up with a running demo in the first case and a blank window in the second. You do need to have DirectX installed though, unless you initialise the Okra window for OpenGL. Also this is a first release so there's some warts. The physics-and-input demo doesn't work (and isn't included) since I initialised Okra with CEGUI and that clashes. If you load these executables from your IDE or Slime instead of your regular implementation you should make sure the libraries can be found! Hopefully this makes it easier for people (on Windows for now) to play with Okra.

[okra-announce] Flock demo released as Windows executable
by Erik Winkels 02 Sep '09

02 Sep '09

I've added a download to a Windows executable of the Flock example. This is mostly a test to see how things run on other people's machine and to find out what the best way to distribute an Okra executable on Windows is. It contains both flock-ccl.exe and flock-sbcl.exe. CCL was my primary implementation when testing on Windows but it was very slow compared to SBCL on a slower Linux machine so I tested with SBCL on Windows and it was quite a bit faster. This needs closer examination :) The demo isn't very fast due to several reasons not in the least because I haven't optimised it. Also while I have been cleaning up the code some compared to the other examples it is still a mess, but due to making examples like this the lispy layer on top of the Ogre bindings is slowly growing. A nice experience while developing the demo was that I used some auto-generated functions that I had never used before and I didn't need to tweak the bindings generator. They worked straight away. Anyway check: http://www.common-lisp.org/project/okra/ The demo's in the Downloads section as flock.zip.

[okra-announce] Okra version 1.6.2.2 committed to GitHub
by Erik Winkels 10 Aug '09

10 Aug '09

I tied up some loose ends this weekend, committed the latest release of Okra to GitHub and tagged it "1.6.2.2". It can be downloaded here: http://github.com/aerique/okra/downloads This will be the last release for a while that brings so many changes at once. Commits should come in bite-sized dosages now. Okra 1.6.2.2 most importantly brings support for C++ overloading, which drastically reduced the size of the blacklist (class members for which no bindings are generated). The support isn't perfect yet: foreign enums are only checked as ":keyword" type and foreign pointers as "'foreign- pointer". This means we cannot distinguish between foreign functions which have different enums or pointers as their only differing arguments. Besides that, there are bindings being generated for only a small subset of all of Ogre's classes. This is because I'm not specifically working on Okra anymore. I'm using it in my own projects and am only adding support for Ogre's classes as I need them. Also in this release is some initial support for CEGUI and Minimal Ogre Collision. (See the Ogre forums if you want to know more about these.) There is some beginning of documentation in the doc-directory. For you OS X users this page might be interesting: http://garaemon.net/wordpress/?p=111 Lastly, I will have to spend some of my free time on non-CL and non-Okra related programming so all-in-all development will be slow for the next few weeks / months. Hope to see some of you at the ECLM in Hamburg this year! (here's some porn made with Okra: http://www.xs4all.nl/~euqirea/perlin-blob/ )

[okra-announce] Okra version 1.6.2.1a1 released
by Erik Winkels 02 Jun '09

02 Jun '09

The very first version of Okra has been released! If you do not have much experience using Common Lisp & gcc and the compiled libraries that come with this release do not work for you, you will probably have a hard time getting this to work. The release can be downloaded from the Okra project page: http://www.common-lisp.net/project/okra/ This release is released as a gzipped tarball since the source is in too much flux right now for other people to contribute. Future versions of the source code will be hosted at GitHub once things have settled down. The project page will stay at common-lisp.net.
