Bad UT8 encoding got with a SQLite3 query

Yes it is not implemented. As in any other open source project it is a question of time and contributions. History of SQLite3 package is much much older than Pharo - original implementation was for Squeak (Avi Bryant's SQLite (v.2) wrapper), I then packaged it up as an MCZ so it did not get lost and a repository on SqS was created. Andreas Raab then contributed to it, he was at my knowledge the only one who really used it in own projects. Later after the closing of SqS was announced I moved the code to STHub. As I already mentioned - code is rather old, based on unmaintained FFI and it should better be redone using NativeBoost because I'm sure meanwhile also SQLite library already made some progress.

Bootstrap for Seaside question

by Torsten Bergmann

>Bootstrap for Seaside is really cool, it allows to quickly build something that looks very polished. Thanks Torsten! You're welcome. In return you should send give a screenshot and short description for the Pharo success story page. The more showcases we have the better it is... Regarding your question: #tbsButton returns a button as the name says. TBSButtonTag is a subclass of WAButtonTag because the offical examples are also using <button> See http://getbootstrap.com/components/#btn-groups But a button should also support #callback: So it is not an anchor by default. Make sure to have a #form: around it and #children is correct. Otherwise callbacks will not work. Note: you can also leave out the whole bootstrap wrapping part and use Bootstrap styles directly, for instance with an anchor: html anchor class: 'btn btn-default'; callback: ... with: [] Haven tested since I have no image at hand - but should work out of the box. One could easily wrap this into a #tbsAnchorButton and "WAAnchorTag subclass: #TBSAnchorButtonTag" supporting the same API. Contribute code + tests if you like. I added you on STHub. Bye T.

Hello, I mass ordered pharo goodies from the Pharo shop for our team. My feed back is that the mug are in a very good quality and are very good-looking, the mouse track pad (orange wave) are just amazing but the stickers are not as good.

Re: [Pharo-users] Writing a GUI - Where to start?

by Picci Pharo

I knew that the problem was here Ben, but i didn't know how to give to the row a symbol. The only way to make it works was to define the widgets into the instantiateModels (that's why #captainButton doesn't give to me any problem). However thanks for your help!

Bad UT8 encoding got with a SQLite3 query

by Michel

Hi everyone, I have a sqlite3 data base which is UTF8 encoded. Accessing to it with a ruby script gives me the right encoding for accented vowel, and doing an hexdump of the file too, but I get a strange one with the sqlite3 package in pharo 2.0. For example, for 'Ã©' (UTF8 0xC3A9) I get 0xA6A9, for 'Ã¨' (UTF8 0xC3A8) I get 0xA6AE, for 'Ã ' (UTF8 0xC3A0) I get 0xA686, for 'Ã¹' (UTF8 0xC3B9) I get 0xA69A, ... Looking at the smalltalk code I didn't see any translation and of course if I attempt to use the UTF8TextConverter I get an error. Any idea ? Thanks in advance. Michel.

Bootstrap for Seaside question

by Johan Fabry

Hi all, I'm using Bootstrap for Seaside to make a small web app for managing the hardware resources (Lego Mindstorms! :-) ) of a course I am giving next semester. Bootstrap for Seaside is really cool, it allows to quickly build something that looks very polished. Thanks Torsten! But now I have a question: I am using buttons at some place in the app (to remove a registered inventory), but I cannot get the callback to work, the examples do not show how to do it. The code I have is below: html tbsButton beDanger; callback: [inv inspect]; with: 'Delete!'. How do I make this work? It seems strange to need to to place an anchor in the button for it to work. ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD lab - Computer Science Department (DCC) - University of Chile

The problem is here rowPlayer add: (textPlayer at:i) ; add:#captainButton; add: (buttonStartingEleven at:i). ]. As you see, the argument of add: is a symbol, but in the first and third add, you add directly a TextInputFieldModel In addition your usage of class inst var is a bit disturbing :) Ben On 22 Nov 2013, at 11:08, prova email <prova213(a)hotmail.it> wrote: > Hi Ben, > here the .st file, there are some comments in italian, i hope it's not a problem. > I know that Spec is the most used and it will be the standard GUI builders in the future, so i'd like to find a solution here, without changing to Morph and Polymorphic. > > Paolo > > From: Benjamin.VanRyseghem.Pharo(a)gmail.com > Date: Fri, 22 Nov 2013 11:04:53 +0100 > To: pharo-users(a)lists.pharo.org > Subject: Re: [Pharo-users] Writing a GUI - Where to start? > > It seems that you return the wrong object somewhere :) > > Could you commit your code somewhere so I can have a look ? > > > Ben > > On 22 Nov 2013, at 11:01, prova email <prova213(a)hotmail.it> wrote: > > I started to use Spec, i love nested layouts and so on.

Re: [Pharo-users] How to load the PetitPHPParser?

by Tudor Girba

Hmm. That cannot really be. PPCompositeParser is defined in PetitParser, but likely the problem comes from the way the ConfigurationOfPetitPHPParser defines the dependency to PetitParser: spec project: 'PetitParser for PetitPHPParser' with: [ spec className: 'ConfigurationOfPetitParser'; file: 'ConfigurationOfPetitParser'; version: 'default'; repository: 'http://source.lukas-renggli.ch/petit' ]. It should load PetitParser from STHub: spec className: 'ConfigurationOfPetitParser'; file: 'ConfigurationOfPetitParser'; version: #development; repository: 'http://www.smalltalkhub.com/mc/Moose/PetitParser/main' Cheers, Doru On Sun, Nov 24, 2013 at 8:43 AM, HernÃ¡n Morales Durand < hernan.morales(a)gmail.com> wrote: > Hi Doru, > > I have tested loading PetitParser from the ConfigurationBrowser and > without, and it is the same. > > > > 2013/11/24 Tudor Girba <tudor(a)tudorgirba.com> > >> From the errors, it seems that you have to load PetitParser first. >> >> Doru >> >> >> On Sun, Nov 24, 2013 at 4:48 AM, HernÃ¡n Morales Durand < >> hernan.morales(a)gmail.com> wrote: >> >>> Loading in Pharo 2.0 gives warning with lots of dependencies: >>> >>> This package depends on the following classes: >>> PPCompositeParserTest >>> PPCompositeParser >>> You must resolve these dependencies before you will be able to load >>> these definitions: >>> PPPHPCoreGrammar >>> ... >>> >>> I have used: >>> >>> Gofer new >>> squeaksource: 'PetitPHPParser'; >>> package: 'ConfigurationOfPetitPHPParser'; >>> load. >>> (Smalltalk at: #ConfigurationOfPetitPHPParser) perform: #loadDefault. >>> >>> >>> >>> Cheers, >>> >>> HernÃ¡n >>> >> >> >> >> -- >> www.tudorgirba.com >> >> "Every thing has its own flow" >> > > -- www.tudorgirba.com "Every thing has its own flow"

Re: [Pharo-users] [Athens] Finding if a line passes through a specific pixel .

by Igor Stasenko

There is some bits which can help you in this regard. The part of it is path tesseleration, which turns any path with complex curves into polygon (which has only straight lines), from there on, i think you can easily calculate the distance between any point and that polygon. Look at AthensCurveFlattener class, and its uses. the entry point is (flattenPath: aPath transform: aTransformation). But be aware that this is not fully integrated yet and subject to change in future. On 23 November 2013 15:20, kilon alios <kilon.alios(a)gmail.com> wrote: > aaaaaahhh come on ...

Deploying a polymorph app - two questions

by kmo

I have written a small Polymorph application in Pharo 2.0. I have some questions about deploying it. My app consists of a single morph. I would like to fill the pharo window with the morph and have the morph resize when the user resizes the pharo window. I'm pretty close to what I want. I have made my morph a subclass of FullscreenMorph and it is filling the window nicely. I just need two things. One - I need to change the pharo window title to the title of my application. I have tried DisplayScreen hostWindowTitle and it seems to have no effect. Two - I need to get rid of the Pharo window status bar - the one at the bottom which shows you the various windows, browsers, and workspaces you have open. Can anyone give me some guidance? Thanks. -- View this message in context: http://forum.world.st/Deploying-a-polymorph-app-two-questions-tp4724525.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] NativeBoost Questions while wrapping FMOD

by kilon alios

However we should acknowledge here that using a FFI, any FFI , in any programming language has the mandatory requirement of knowing C. I certainly do believe that documenting Nativeboost is extremely important for helping people to port C libraries to pharo and making Pharo far more useful but we should not kid ourselves. Coding with Nativeboost even though its inside Pharo , even though its smalltalk syntax, even though it has the tools to make your life easier, its still C coding or even Assembly coding if you are brave enough to use the inline assembler. I want to help with documentation the problem is that I dont know a lot of stuff about Nativeboost besides the basic pointer things I did with NBOpenGL.

I really think that NativeBoost MUST HAVE a decent documentation. It is a central part of Pharo and Igor you should do something about it.

I agree with Stephan that it is less code to write a browser-like user interface with Glamour. That is the advantage of using a domain-specific solution, like Glamour. However if you are writing something that falls outside of the domain, i.e. a user interface that is not a browser, it will become difficult with Glamour.

[launcher] templates from fixed URLs

by btc＠openinworld.com

Hi Damien, I like the PhLFixedURLsTemplateGroup you just added to directly reference specific urls like Pharo 3.0 latest. I corrected a problem with Settings. Also I think its useful to be explicit about the ones that refer to 'latest' so I made that change. Could you review these. The next great thing would be to allow users to add their own fixed urls without coding. btw, I was going to follow your example to change PhLTemplateGroupRepository>>refreshLocal to >>refreshFast but it seems the only sender is itself, and also inserted breakpoints do not trigger. Looks like it is surplus to requirements. cheers -ben

Re: [Pharo-users] NativeBoost Questions while wrapping FMOD

by Igor Stasenko

So, here the changes which should work (but i didn't tested). And being on your place, i would get rid of FMOD_SYSTEM class, because you can just subclass FmodSystem from NBExternalObject directly (and use it in signatures) and so it will be holding the handle, and naturally work as a representation of external entity. Also note that in this case FmodSystem is alias to C FMOD_SYSTEM* so, for every function which expects FMOD_SYSTEM*, you should just use FmodSystem, and if it expects FMOD_SYSTEM**, you using FmodSystem* basically, same as if you would have: typedef FmodSystem FMOD_SYSTEM*; in C.

Hi & welcome. I'm not in a position to help directly, but just suggest that the more specific advice the advice you are seeking, the more use it is to paste here the specific code you have defined and the specific Workspace snippets you are executing. This reduces the chance for misunderstanding. Also while you may only know enough to ask about "X", someone looking at your code might be able to advise that you should really be asking about "Y" and here is its answer "Z". The code you paste should be reduced to the minimal self contained app that highlights your need. hope things are well with you, cheers -ben steliosgan wrote: > First of all...Thank you all for the instant response (ÎÏÏÎ±ÏÎ¹ÏÏÏ ÏÎ±ÏÏÎ¹ÏÏÎ·). > I would like more precise directions as I am soooo new at this.

How to combine Pharo Desktop and Seaside?

by Torsten Bergmann

You can initialize your instance variable in an initialize method WAComponent subclass: #PrintHtml instanceVariableNames: 'tasks' classVariableNames: '' poolDictionaries: '' category: 'KillerApp-Web-UI' Then a method to initialize on the instance side PrintHtml>>initialize: initialize "initialize the receiver" super initialize. tasks := #('read' 'before' 'you' 'try') If you send #new to a class this #initialize method is automatically called. If you do not want it use #basicNew. So if you enter PrintHtml new in a workspace and select "Inspect it" to open an inspector on the new object this method gets called and therfore you will see that the instance variable should have the collection as contents. Side note: Do not forget the "super initialize" in this method - otherwise superclass initialization for seaside components is not done. Then use a normal rendering method to display the ivar in the browser renderContentOn: html html orderedList list: tasks If I understand you correctly you want to know how you acces the Seaside generated code for a WAComponent subclass also in a workspace. This is easy: |component| component := PrintHtml new. "your seaside component" WARenderCanvas builder render: [ :html | html render: component ] which should return the generated HTML: '<ol><li>read</li><li>before</li><li>you</li><li>try</li></ol>' now. That is one way. The preferred way for Seasiders is to directly look at the generated HTML code in the webbrowser. Just go to your app: http://localhost:8080/killerapp Down at the bottom you will find the seaside development toolbar (only visible when developing) and then click on "Halo". Now Seaside renders a rectangle around each component and you can click on "Source" to Switch to the source of a component. Also try the other buttons there. For sure you should read one of the introduction stuff on Seaside, I would recommend the online Seaside book: http://book.seaside.st/book Bye T.

How to combine Pharo Desktop and Seaside?

by Torsten Bergmann

Hi, If you want to write your collection to a static HTML page you can |aCollection| aCollection := #('Smalltalk' 'Object'). FileSystem workingDirectory / 'test.html' writeStreamDo: [:stream | stream nextPutAll: '<html><head></head><body><ol>'. aCollection do: [:each | stream nextPutAll: '<li>'; nextPutAll: each asString ]. stream nextPutAll: '</ol></body><html>']. and then serve it from an external webserver (like Apache or Nginx). But this is static html file generation. I'm sure you want something more dynamic. So you can serve the contents right from the image using one of the Smalltalk webframeworks like Seaside or Aida. Here is a short Seaside HOWTO for this: Prepare an image with Seaside ============================= - download Pharo 2.0 from www.pharo.org - start it, then select "Tools" -> "ConfigurationBrowser" from the world menu to open a list of additional loadable packages - search for "Seaside3" and click on "Install", this will install the seaside web framework into your image - When loading is finished just open a workspace ("Workspace" from world menu) and evaluate ZnZincServerAdaptor startOn: 8080 This will start a local webserver right from your Pharo image on the given port. - check with a web browser (Firefox, Chrome, IE, ...) that Seaside is running by opening http://localhost:8080 There you can browse first Seaside examples. As an alternative to the above steps you can also download a premade Seaside distribution from http://seaside.st Implement your own webapp ========================= - open the Nautlius System browser ("SystemBrowser" from the world menu) - implement an own Seaside component class WAComponent subclass: #MyHome instanceVariableNames: '' classVariableNames: '' poolDictionaries: '' category: 'KillerApp-Web-UI' - now register this class for Seaside by evaluating the following expression in a workspace WAAdmin register: MyHome asApplicationAt: 'killerapp' This registers your component as an own custom seaside application under /killerapp. - so if you point your browser now to http://localhost:8080/killerapp you will see an empty page - but it means you application is there but has not yet some content - now implement an instance side method called #renderContentOn: on the MyHome class renderContentOn: html "Render a collection as html list" |coll| coll := #('Seaside' 'is' 'really' 'cool'). html orderedList list: coll. - refresh your browser on http://localhost:8080/killerapp you will now see the contents of the collection How to continue =============== Read books, try to implement something and if in doubt just ask on the mailinglist. There is also a seaside mailinglist http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside Learn about Pharo by getting on of these books: http://pharobyexample.org/ http://rmod.lille.inria.fr/pbe2/ learn about Seaside http://book.seaside.st/book learn about Smalltalk in general with these free books: http://stephane.ducasse.free.fr/FreeBooks.html

When a Spec UI is build, the spec are looked up on class side. But in some special cases you can provide directly a SpecLayout object to a model. Why on class side?

My understanding is that both Spec and Polymorph are built on top of Morphic. I only looked at code example and brief tutorial for both of them, but it seemed to me that Polymorph was easier to grasp: it's quite obivous in the code where and how the widgets are built.
