by Torsten Bergmann

Need an easy way to convert HTML into PDF for printing? The project http://wkhtmltopdf.org can help you here. If you want to use it from Pharo just check out: http://smalltalkhub.com/#!/~TorstenBergmann/WKHTML2PDF This project allows you to easily use the library. First select the engine: HTML2PDFConverter useExecutable. or HTML2PDFConverter useLibrary. and then convert: HTML2PDFConverter convert: 'http://www.pharo.org' toFile: 'pharo.pdf' to get a printable version of the Pharo homepage. As ever docu is on the STHub project website. It uses NativeBoost to call the library and OSProcess to call the executable. Bye T.

Re: [Pharo-dev] MultiByteFileStream #converter - what does it do?

by Sven Van Caekenberghe

Yes, one day we have to do this. There is also Xtreams which is a broader, more interesting way of rethinking the subject. But the main issue is: the stream API is way too broad, so any change will involve slimming down or changing the API and hence the users. That is a lot of work. > On 18 Dec 2014, at 23:51, stepharo <stepharo(a)free.fr> wrote: > > Sven > > could we not nuke > > MultiByteFileStream > > and use ZnCharacterStreams? > > > Le 17/12/14 19:54, Sven Van Caekenberghe a Ã©crit : >>> On 17 Dec 2014, at 19:42, sheridan(a)sheridan-mahoney.com wrote: >>> >>> Hi there, >>> >>> I am still working my way through MultiByteFileStream tests, and have come across the messages #converter and #converter: .

GSpotter fonts of evaluation results

by stepharo

The fonts used by GSpotter to display results does not change when changing size and this should be fixed for demo for example. Stef

Sven could we not nuke MultiByteFileStream and use ZnCharacterStreams?

Re: [Pharo-dev] 14615 Change in Delay semantics when high priority timer event loop stopped

by stepharo

Ben I would love to be able to answer a clever answer but I'm not deadlock free when it comes with concurrency. I would like igor to answer because he has accumulated experience of concurrent matters. Now I have the impression that I would go for 2 because it opens more doors and that 1 does not really help.

Re: [Pharo-dev] RBEnvironments allClasses/Traits/Meta ...

by Yuriy Tymchuk

Iâm ready to help with this issue, but as far as I can tell, itâs not hard to implement the mentors. Here we should decide on the meaning of the phrases. What are "all behaviorsâ and so on. The reason of the refactoring that Iâve done was that there were two methods with similar names that were doing different things.
