WOW! Great work Stuart, that's fantastic! :)

Cheers. ..  

I will try and put up a more detailed blog post in next few days..

If anyone has a mac to run nodebox on it might be worth trying to spot any differences (I'm not sure the
bit where the creatures rotate at the beginning is correct for instance)..

Nodebox compatiblity milestone - Evolution exampleruns unmodified

Stuart Axon — 2013-04-09T14:01:24

Hi,
   Back in 2008 when I first saw nodebox, it was the Evolution example
http://nodebox.net/code/index.php/Evolution that made me sad I couldn't 
nodebox on linux...  luckily shoebot was here, though it couldn't run
that particular example yet.. it had puredata integration, a gui and
some nice drawing examples..

Today though, evolution runs completely unmodified on shoebot !



Downloading and running it
sbot -w evolution.py
See's little beasties battle it out for survival (possibly too fast in shoebot)
- for more information read the page on the nodebox site.


Luckily it just involved uncommenting some of our cmyk code, a little work
+ adding a little more to our nodebox compatiblity code (see nodebox-lib).


Obligatory pic..

Known bugs:
Running this did expose a memory leak (issue 33) - also I'm not sure
if colours are 100% correct yet.


TL;DR
The evolution nodebox bot is pretty cool, and see's little creatures battle
it out to survive in the genepool - it runs a lit

Testing the list, please ignore

That could be useful - another solution is to make a blacklist and add the word 'walid' since I'd imagine typos like this one will probably happen again.

Color examples

Stuart Axon — 2013-03-20T18:01:53

Been playing with some things to get the color examples working again ..  the background on hair.bot comes out bluish when I'm pretty sure it should be brown.

Pretty sure this came up before, if anyone has any time to look at it or a clue why it might be doing it then please mention it !


In other news, it turns out the cairocffi branch works on pypy, though no gtk on that one yet - but still; pretty promising :)

A couple of shoebot experiments..

Hi,
  Just uploaded a couple of shoebot experiments with movement.  - Always fun building stuff with shoebot + fixing the bugs as they arise :)

Re: Nice example on nodebox site - Fireworks

Stuart Axon — 2013-01-21T10:56:28

I tested this on the weekend using svg output and got an 11mb svg !

When I tried to open this in inkscape, it used all the memory before crashing.

PDF output was fine, + running in window mode.


There's probably something suboptimal in the cairo use SVG.

Scripted publishing [RFC]

Stuart Axon — 2013-01-18T12:18:12

I'd like a 'publish' option, it would take shoebot output and run it through some sort of scripted process.
It would work with hooks at various points (e.g. frame has been generated)

It could work like this:

--publish video:somevideo.avi
--publish html:some_directory

--publish gist:github_gist

The first part is the script/plugin, then the parameters.

video plugin - take each frame and pass it to something like gstreamer or ffmpeg with sensible defaults to create the output video.

html plugin -  build an html page, using sphinx (like processing/contextfree have) for the script, with a screenshot.

gist - call the html plugin and publish to a github gist, with screenshots uploaded and linked.



The above plugins are just examples... something like this would make it easier for us to add desired functionality to IDE plugins.


.. I really like the idea of a plugin that publishes to the shoebot site, however because someone could publish a dangerous script, we'd probably need some sort of vetting.

Interesting result, it's possible that something pathological could be happening with memory, might be worth seeing how much memory uses when running different bots.

Nice example on nodebox site - Fireworks

Stuart Axon — 2013-01-16T15:29:55

This example from the nodebox site worked in shoebot first time (always nice).

http://nodebox.net/code/index.php/Fireworks

 
So might be worth including .. as always I'd like it to have better performance (or at least progressive rendering), but c'est la vie..

Pycharm license for shoebot devs 2013

Stuart Axon — 2013-01-10T11:46:56

Hi,
  I've made inquiries with Jetbrains and we can use Pycharm for shoebot development for another year.   
If anyone is interested then reply and I will forward the license info.

Their email is below - I guess logo considerations would be something to discuss when we update the site, if lots of people are find pycharm helpful.

Image paths for examples, assets etc

Stuart Axon — 2013-01-07T12:39:01

Running examples can be a pain if you're not in the right directory -
I was thinking of adding some string processing to image + anything that can uses assets.

%(sbot.dir)s        - directory of currently running bot
%(sbot.assets)s   -  shoebot assets directory
%(sbot.examples)s   - shoebot examples directory

 

Any objections/suggestions ?
