Re: [Pharo-users] SPEC: accept by Tab ?

by Hartmut Krasemann

The error I made: textinputField acceptBlock does not work. the action seems to take a morph. The following worked for me. textinputField bindKeyCombination: Character tab toAction: [:morph| "hereTheAcceptBlockContent." textInputField text: morph text]. But this is ugly. I use a spec with 5 TextinputFields. with or without "asKeyCombination" the additionalKeyBindings only sometimes work, ie. on some of the fields in a spec, but not all (this was even dynamically changing). In those cases where the additional binding of the tab works, the navigation fails. It seems that the tab is consumed either by navigation or the additional keyBinding. And which one is decided by chance. So this will not help me. Any idea?

Re: [Pharo-users] [ann] bloc & cairo+morphic

by Tudor Girba

Hi, It seems that my initial message generated a misunderstanding. My original blog post was meant to communicate two things: 1. That the known Bloc project has received a new feature that the community raised as a problem (i.e., host & backend). 2. Address the other concern that the community raised: how to sustain the Bloc development in terms of engineering effort. This is why we announced the financial support for the work of Alex that is valid from this point on. The post was certainly not intended to overlook the people that contributed to the overall project. I apologize if it looked like this. To clarify the historical perspective, we now added an explicit history page on the official project page: https://github.com/pharo-graphics/Bloc/blob/master/HISTORY.md I also changed the blog post to more clearly communicate the intent: http://www.humane-assessment.com/blog/bloc-flexible-backends-hosts/ I hope this addresses the concerns. I am really excited that Alain joined and that we can get even more traction around Bloc.

Re: [Pharo-users] [Zinc] ZnInvalidUTF8: Illegal leading byte for utf-8 encoding

by PBKResearch

With reference to Norbert's comment, there /may/ be an ambiguity about the word 'header' in Udo's reply. It could refer to the http HEAD section, in which case Norbert is of course right. It could also refer to the <head> section of the html file, which is part of the content of the http response. If it is the latter, this is similar to a question that Paul deBruicker posted last November ("[Pharo-users] ZnClient GET, but just the content of the <head> tag?"). I tried the method I devised for Paul's case on Udo's problem website, and read the html header with no problem. Incidentally, the header includes 'charset=iso-8859-1', which does not agree with Sven's findings. In case it is of interest, I used XMLHTMLParser to read and parse the header. Try the following in a Playground: par := XMLHTMLParser onURL: 'http://www.darkreading.com/partner-perspectives/malwarebytes/locky-returns- with-a-new-(borrowed)-distribution-method/a/d-id/1328723'. par parseDocumentUntil: [|top|(top := par topNode) notNil and: [ top isElement and:[ top isNamed: 'body']]]. par parsingResult findElementNamed: 'head'. If you 'Do it and go', the full header appears. The way I get it to stop after the header may not be quite correct, because it uses XMLHTMLParser>>topNode, which is a private method. On the other hand, I can't see how to make the stop condition for XMLHTMLParser>>parseDocumentUntil: depend on the parsed results without using a private method.

Re: [Pharo-users] Intro to git-only Pharo

by Dimitris Chloupis

So far coding solo with git and filetree has been painless and straightforward for me, I use github for public and gitlab for private projects. I do not use configurations other than copy pasting one for adding my project in Package browser. I do not use versioner because a simple copy paste is enough. I do not use iceberg I prefer my favourite git client "gitup". My experience has been both simpler, easier and far more reliable than working with the pharo vcs and smalltalkhub. But I was already familiar with git because I was already an experienced python coder , and still am, way before working with Pharo. I have made a tutorial about Pharo and git that can be viewed here. Its with sourcetree not gitup because gitup is only available for macos and I wanted to make a tutorial that would work on all 3 major desktop OSes. https://www.youtube.com/watch?v=n2WNYDtO0cE On Thu, May 11, 2017 at 9:56 PM Thierry Goubier <thierry.goubier(a)gmail.com> wrote: > Le 11/05/2017 Ã 20:52, Stephane Ducasse a Ã©crit : > > Joachim > > > > many people are using Pharo to develop ***COMPLEX*** Pharo applications > > and it works.

Re: [Pharo-users] [Zinc] ZnInvalidUTF8: Illegal leading byte for utf-8 encoding

by Norbert Hartl

Just to mention. If you are not interested in the content body you could do a HEAD request instead of GET.

Re: [Pharo-users] [Moose-dev] [Pharo-dev] [ann] bloc & cairo+morphic

by Stephane Ducasse

BTW for an historical perspective RMoD me and igor were also involved far less than the effort of alain but as he mentioned it we collaborated on it. I spent time on documenting several versions and I stopped disgusted to see the total lack of attention for comments. Then Rmod paid nearly a year of effort on Athens, SDL20 support, a year on TxText. I find really strange that we are not even mentioned in any support.
