While this sounds nice I do wonder if there is some simpler solution to common issues. When I create a top level category, for example, the logical thing would be for focus to go to the Class template. Similarly, when I click on the class category and the system presents the method template it seems fairly logical to put the focus on the text there. As it is, unless I've missed something, when a method template is automatically created in the source panel it is highlighted as if for editing but focus has to be switched to start editing, which removes the highlighting and so I have to re-create it with ctl-a! All this involves a lot of moving from keyboard to mouse and back again. Is there some shortcut for simply changing focus from panel to panel in the browser? Thomas Worthington

The files are ~500MB each This uses code that is already in Pharo: '/tmp/foo.txt' asFileReference readStreamDo: [ :readStream | | lineReader | lineReader := ZnLineReader on: readStream. Array streamContents: [ :output | | line | [ (line := lineReader nextLine) isEmpty ] whileFalse: [ output nextPut: line ] ] ] Works with any line end convention. Check the class comment of ZnLineReader. Sven

Re: [Pharo-users] Adding Websocket support to Zinc

by Andy Burnett

Hi Stef, There was an issue of commercial confidentiality about the agreement, which is why I haven't published a figure to the whole list. So, I will mail you directly. Cheers Andy <<< Hi andy How much money would it be? In the past ESUG supported open-source bounty so may be you can contact them too. Stef >>> > I think we need Websocket support built into Pharo. So, rather than talk about it, I have contracted with Sven to build it into Zinc. We hope to have a running version in the early Autumn. > > The purpose of this email is: > ?

To ask if anyone else feels that they would gain commercial benefit from using this feature, and if so, whether they would like to help cover the cost. If so, please drop me an email. > Cheers > Andy

The project is at http://ss3.gemstone.com/ss/VimPharo.html ( until I move it to github ;-) ). I'm very close to having most of the basic navigation shortcuts in normal mode implemented. In the long term, I think what would be the most powerful for Pharo is to reimagine what the vim shortcuts would be if they operated on live objects (AST) instead of text snippets...
