Re: [Pharo-project] Where to put removed stuff?

On Stackoverflow someone asked what to do with good code which isn't needed anymore. This was the answer: <blockquote>As an answer, please consider this short story: The dead code Collector: Bring out yer dead code. Man with dead code : Here's one. The dead code Collector: That'll be ninepence. The dead code: I'm not dead code. The dead code Collector: What? Man with dead code : Nothing. There's your ninepence. The dead code: I'm not dead code. The dead code Collector: 'Ere, he says he's not dead code. Man with dead code : Yes he is. The dead code: I'm not. The dead code Collector: He isn't. Man with dead code : Well, he will be soon, he's very ill. The dead code: I'm getting better. Man with dead code : No you're not, you'll be stone dead code in a moment. The dead code Collector: Well, I can't take him like that. It's against regulations. The dead code: I don't want to go on the cart. Man with dead code : Oh, don't be such a baby. The dead code Collector: I can't take him. The dead code: I feel fine. Man with dead code : Oh, do me a favor. The dead code Collector: I can't. Man with dead code : Well, can you hang around for a couple of minutes? He won't be long. The dead code Collector: I promised I'd be at the Robinsons'. They've lost nine today. Man with dead code : Well, when's your next round? The dead code Collector: Thursday. The dead code: I think I'll go for a walk. Man with dead code : You're not fooling anyone, you know. Isn't there anything you could do? The dead code: I feel happy. I feel happy. [the dead code Collector glances up and down the street furtively, then silences the dead code with his a whack of his Ctrl-X] Man with dead code : Ah, thank you very much.--BraveSirFoobar</blockquote>.

Re: [Pharo-project] Continuous Integration Server for Pharo?

by Simon Denier

As 'developer by default' of TestServerSimple, I can just: TestServerSimple is just that, something to automatically download the latest version of packages, run the tests, and send a small report by mail. Right now the server works with Metacello configuration, is still not bulletproof to some exceptions (like a TimeOut on a distant repository), and used to work with Flair config or directly with Monticello packages. Now I dont have the time or the energy to invest more in this thing, so I would be happy to beta-test integration servers on Moose. The features you describe are interesting. So once, everybody has settled on some good solution (be it BB, Hudson, ...), just come to me with a good tutorial :) On 28 nov. 2009, at 09:23, Bart Gauquie wrote: > Dear all, > > I come from a Java world and there we use for instance : http://hudson-ci.org/ > to do a continuous integration build.

Re: [Pharo-project] file encodings

by Tudor Girba

Hi Nicolas, Thanks for the tips. I am a bit alien to the topic of encodings, so I will ask a couple of silly questions. How exactly do I deal with another encoding? For example, why does this work with Utf-8, and what would I do if I encountered another encoding? Or more general, how can I find out what kind of converter I need for a given file?

I put the Sound and MorphicExample code that I removed from the core into separate SqueakSource projects. Like this the main repository does not get cluttered with unloaded code.
