[Pharo-project] Changes for PharoDev

by Mariano Martinez Peck

Hi. Today, we have a good way to manage packages/projects (Metacello) and a good way to automatically build images (Hudson). Several months ago, I suggested to remove the PharoWeb image for several reasons (I won't mention them here, check in the mailing list). People have different ideas of what to put in dev images and we cannot all agree. So, I won't say anything new, but just suggest something: Pharo1.2 is beta and it is almost there. We shouldn't change it that much before the release. So, I would include in the Pharo1.2 image what we were including more or less in Pharo1.1. The dev image is being built using ConfigurationOfPharo. This conf, has defined different groups, included the 'Dev' group which us used for building the dev image. Now, what about adding to ConfugurationOfPharo, much more projects, and creating groups for them. Then, with Hudson we can REALLY EASY build another image, but not with the 'Dev' group, but with 'Web' for example. Web is just an example, but we can put as much as we want. I would create a PharoWeb which can contain ALL seaside related stuff (core, addons, pier, margitte, blah). We can use ConfigurationOfSeaside. The same for Aida. We can also add WebClient, Zn, seaside testing, or whatever web related you want. Then we can create a PharoExtras, where we can put (in addition to pharoDev) what it is now in PharoNonCore, plus MemoryMonitor, XMLSupport, Mocker, AutoTest, KeyBindings, etc etc etc. Things that are not "dev tools" but that they are working in pharo and that would be welcome for newcomers. Last comment is that it would be nice if all this can be done using the new symbolicVersions of the new Metacello version. what do you think ? cheers mariano ps: if you like it, we need help to update ConfigurationOfPharo and probably all its referenced confs (to use the stale symbolic version)

Try this: | absentBlock | absentBlock := [ #bar ]. [ 1000000 timesRepeat: [ dict at: #a ifAbsent: absentBlock ] ] timeToRun Levente > > > >

Re: [Pharo-project] Socket question (Was Re: Xtreams up to date)

Based on what I know about TCP sockets it doesn't make sense to me. AFAIK to get both ends of a connected TCP connection (lacking a socketpair call) I need 3 sockets. A listening socket, a client socket (doing connect) and finally the server socket that comes out as a result of accept on the listener. So I'd expect to see something like this in the setUp: There's a way to use only 2 sockets and this causes the problem. If you use #listenOn:, then there will be no backlog and the listening socket will accept the connection. If you use #listenOn:backlogSize: instead, then it should work.

There are two reasons: (1) it is stronger, and (2) it appears in more places (e.g., at the bottom of the scrollbar). This means that it will compete for my attention with more force. This might be your intention, but it is not mine because it takes away from my main focus which is the content. > I admit that I do like the blue for selections. However, I find that the blue gradient on the buttons is difficult to see clearly. I suspect this is because the chosen blue has high contrast against the white background of the list but *extremely* poor contrast with the grey button/frame background. If you look at the browser in greyscale, the difference stands out starkly (see the attached image). I also find all of the buttons without white borders seem to blend into the background so much as to become difficult to distinguish. Otherwise, I do like it :)

OK, great. Thanks everybody who answered. The response from HernÃ¡n mentioning the createNewIconMethodsFromDirectory: method looks interesting. I'll try the other methods too. Thanks. -- Dimitry Golubovsky Anywhere on the Web

I submitted them into PharoTaskForces because I've no access to lukas repo, and I don't know what does he what to do with those changes... I had the impression (but I can be wrong) that it was Lukas' strategy to maintain just one 'head/trunk' version of his packages. So I was a bit surprised that they didn't load in 1.2. Since others reported OB to load, that meant patched versions were used from somewhere else. What is the official OB repository ? Sven
