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.

Re: [Pharo-users] Mugs, mouse mats, stickers

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. There is a problem the circle mismatches the logo (see pic in attachment, I don't know how to explain that) sticker page: [image: Images intÃ©grÃ©es 2] a sticker stuck on a computer: [image: Images intÃ©grÃ©es 1] Best, 2013/11/25 Jeff Gray <jeff(a)rogerthedog.com> > Hi Esteban, > Did you see the stickers we have in the Pharo shop?

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!

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 TextInputFieldModelIn 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.

It is the newest and designed to be the most capable. It is also the way forward, it will be the 'standard' GUI builders in the future. We know that the documentation right now is far from optimal.

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. I have trouble understanding how the job is done in Spec. On the other hand, Spec seems to have a lot of users in this mailling list. > > > > To sum up this thread with many different options proposed, what would be the right path for a newbie like me ? > > > > Thanks in advance ! > > > > > > ---> Save our in-boxes! http://emailcharter.org <--- > > Johan Fabry - http://pleiad.cl/~jfabry > PLEIAD lab - Computer Science Department (DCC) - University of Chile > > <PBE-SquadraPROVA.st>

I know nothing about the sqlite3 code, but if you canât find unit tests doing non-ascii stuff, and you can't find conversion code, than the original author(s) probably just didnât implement it. I might be wrong, but that would be a shame, since utf-8 encoding/decoding is fully supported in Pharo. Sven

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.
