Re: [Pharo-dev] Pharo Development Robustness (was: Why Bloc?)

by stepharo

Hi sean Thanks for this mail!!!! About bloc --------- I discussed with alain about this point at ESUG. Alain would like to finish the handlers and a couple of other points, clean everything and release a first version. The problem is that alain is often doing trial and changes. Here is where I think you can help: - turn some of the example for the layouts into tests - start to clean/revisit some basic morphs so that we can turn them into bloc counterparts easily. - I started to look at buttonMorph* - I started to rewrite MenuMorph because it is full of old code. I would like to remove the direct manipulation because it adds a lot of problems. If you want to join let me know. About TxText ------------ - Igor added morph - we should make sure that the configuration is loading in 40 -now mocketry is loading in 40 so the configuration of TxText should be working. - we should check the current use of TextMorph and friends and use TxText Stef On 27/8/14 01:48, Sean P.

Re: [Pharo-dev] Fwd: A UTC based implementation of DateAndTime

by stepharo

Sven long time ago I was believing that this is important to have a nice and rich model for the core but on dates/calendars it is complex so what I would do is to have a small and working code for Date/ and make sure that more complex model can be loaded by people.

So, what is scheduled is an RMoD sprintâ¦ which is kind of a small one.

Re: [Pharo-dev] PharoLauncher on Windows not the latest version

by Tim Mackinnon

Hmmm that sounds strange (it could be I messed something up) - but did you get your zip file from: https://ci.inria.fr/pharo-contribution/job/PharoLauncher/885/PHARO=30,VERSI… ?? I just tested that one (but on OSX) and it shows my change as well as templates for Moose 5 and Pharo 4. Iâve just pushed another change (which would be 886), which also fixes a bug Stef mentioned (if underlying files change, it used to terminate instead of refreshing) - that should build shortly. However - the links on SmalltalkHub are still pointing to images from Jun (the Hudson jobs arenât triggered automatically it seems) - so I think you might be running something other than what you think you are running. Anyway - let me know what happens, and Iâll try and talk to Damien (who is on holiday) - and sort it out if Iâve broken it.

Are we talking a TextEditor anymore, or are you moving into the domain of a DocumentEditor? Wouldnât it be a better delegation of responsibility to have a text-editor dealing with nothing but text, but also accepting shapes where it is not allowed to render text (and only that), and leave compositing of textEditor and other morphs up to a DocumentEditor. IMHO, if you canât save the contents as an .rtf or something similarly simple, itâs not really a *Text*Editor anymore. Cheers, Henry

Re: [Pharo-dev] PharoLauncher on Windows not the latest version

I mean PharoLauncher cannot download Pharo 4 because it displays no such option. No Moose 5 , etc etc. Its also the old GUI. So this must be the latest version, I am not near my window pc now at work so I will try tomorrow the developer mode to see exactly which version of PharoLauncher it is. Are you on windows ?

Re: [Pharo-dev] PharoLauncher on Windows not the latest version

by Tim Mackinnon

What do you mean by Pharo 4 template? I just made a contribution yesterday - watched it build the new zip file, and I just downloaded that zip and I am seeing a âPharo 4.0 (beta)â template tree? Just to check you are using the latest version, if you right click on a template and choose âCreate Imageâ - does it prefix the parent of the template to the suggested name (e.g. Pharo 3.0-latest)? (this was the change I made). It might be worth checking your settings as well (click on the icon lower right) and check that you havenât accidentally unticked the Pharo 4.0 repository.
