Re: [Pharo-project] Fuel bug: infinite recursion in "analyzer when:substituteBy:"

by Mariano Martinez Peck

For this "problem" at least it is documented in http://rmod.lille.inria.fr/web/pier/software/Fuel/Version1.7/Hooks in the section "Substitutes on Serialization" On Fri, Nov 25, 2011 at 8:46 PM, Yanni Chiu <yanni(a)rogers.com> wrote: > On 25/11/11 5:26 PM, Martin Dias wrote: > >> Hi Yanni >> >> This is a feature or a known issue, I am not sure yet! >> > > It makes sense why it is the way it is (as you've noted below).

Re: [Pharo-project] Morphic replacement

by Alexandre Bergel

I guess the absolute coordinates are kept in a cache or something? This is probably necessary when you want to redraw inner widget without redisplaying the nesting ones Alexandre Le 25 nov. 2011 Ã 13:22, Fernando Olivero <fernando.olivero(a)usi.ch> a Ã©crit : > Glad to be able to say: yes! > > Each object speaks in its own coordinate system, its parent already > internalized the point. > > Suppose we have a click, announced by the mouse at a given point, > given in Display coordinates. > > From now on we go, from the display, to the view , to the scene, to > the shape, and on each step the parent deals with a point in its own > coordinate system, and passes on the internalized click to its > children. > > Views present a scene, consisting of shapes, at a given viewport of the display. > > Makes it a lot easier when you are programming the interaction of > custom widgets, to always deal with local coordinates, and greatly > simplifies the event handling code as well. > > > On Fri, Nov 25, 2011 at 5:00 PM, StÃ©phane Ducasse > <stephane.ducasse(a)inria.fr> wrote: >> did you kill the absolute coordinates? >> >> say yes please :) >> >> Stef >> >> On Nov 25, 2011, at 11:00 AM, Fernando Olivero wrote: >> >>> Dear all, >>> >>> I've been working on a hole replacement of Morphic myself, because if >>> was tired of fixing Morphic (or porting CUIS Morphic into Pharo), and >>> found much more productive the approach of rewriting it from scratch. >> >> excellent! >> >>> >>> In my expierience, i was 100% more productive by not trying to be >>> backward compatible with Morphic, Polymorph , etc. >>> >>> I found it easier to come up with a new set of widgets (EntryField, >>> AutoCompletionEntryField, Button, Label, Column, Row, >>> ScrollableColumns) from scratch.

[Pharo-project] gettext implementation

by CÃ©dric Ternon

Hi, I'm trying to use the gettexts packages under seaside, I firstly posted to the seaside mailingList but Philippe Marschallrecommended me to try to reach mister Hilaire on this ml. I have success to use the gettexts packages creating a .pot file, translate the website in poedit, creating the .mo and having the website in different langages. The problem occurs when I try to create a .po file to continue an incomplete translation, The previous messages follows : Hi, I'm trying to use the gettexts packages for seaSide. I finally achieve to create a .pot file, translate it with poedit and make the website translated. But now, I'm trying to create a .po file, that is a .pot file with the strings already translated and the strings remaining to translate. (a .pot file beeing an empty template to begin without any translations) We followed this tutorial : http://code.google.com/p/seaside/wiki/Gettext The versions used are : Seaside-Gettext-Core-NorbertHartl.10 Seaside-Pharo-Gettext-Core-pmm.1 Name: Gettext-HilaireFernandes.22 When I simply try : GetTextExporter new exportTranslator: NaturalLanguageTranslator current. I got : http://pix.toile-libre.org/?img=1322152172.jpg I've got the same result with any GetTextTranslator I have tryed to look for an implementors of the method "translations" but no one is implementing it, is a pkged missing? I've also tryed to replace it with 'class translators' but this sound wrong and give me another unrelated error. Thanks in advance for your help, ----- Philippe answer : It looks like you're using GetTextExporter instead of WAGetTextExporter. Can you load Seaside-Gettext-Examples and evaluate WAGettextExample export and see if that works? Cheers Philippe ----- Hello, Thanks to help. It works fine but it creates a .pot file. My goal is to create a .po file : when a site is already half translated, I'd like to create a .po file a translator can use in poedit. So the translator only has to translate the half not yet translated (and maybe bring some little corrections to the half already translated.) WAGettextExample export calls WAGetTextExporter new exportTemplate wich calls self exportTranslator: nil and we go there exportTranslator: translator "Export translation files. the file extention is 'po', or 'pot' if translator is nil " when the translator is nil, everything works well. when I try with a translator it breaks here : translationFor: aKey in: translator translator ifNil: [^'']. translator translations at: aKey ifPresent: [:s | ^s]. "If we have old camelCase translations, make space-separated words" translator translations at: aKey toCamelCase ifPresent: [:s | (s includes: Character space) ifTrue: [^s]. ^s fromCamelCase]. ^'' --------------------------- Now, I have tried to change the code of translationFor: aKey in: translator in this way : translationFor: aKey in: translator |result| translator ifNil: [^'']. result := (WALocalizationContext new translate: 'aKey'). (aKey equal result) ifTrue: [^'']. ^result. That is maybe horrible to use the WA things at this level but I tried to make it works and the only way I achieve to translate things is at the WA level.
