The implementation from PositionableStream cannot easily be borrowed because there seems to be no way to reset the position. Is there a plan to support the most commonly used messages from the normal streams? The Stream API is much too wide, it has to be reduced and split in a number of elementary streams that can be composed to add desired behaviour (like character encoding/decoding, buffering, line end translation, ...). Positioning in a stream (moving backwards without restrictions) is not generally possible (think of a network stream), that is why it is not implemented. > Bernhard > >> Am 30.12.2017 um 18:03 schrieb Sven Van Caekenberghe <sven(a)stfx.eu>: >> >> https://ci.inria.fr/pharo-contribution/job/EnterprisePharoBook/lastSuccessf… >> >> 1.4.

Re: [Pharo-dev] Pharo 7 crash on Mac

by Bernhard Pieber

Hi Stef, I feel your pain! Especially for the stable version (6.1) this is very unfortunate. I hope the problems are gone with the new VMs Esteban will release. Happy New Year!

Re: [Pharo-dev] Streaming over a UTF-8 encoded file using upToAll:

Hi Henrik, Thanks for the fix. I just saw it today. In the meantime I have created a pull request with another fix. To be honest, I have just taken the working implementation from Squeak: https://github.com/pharo-project/pharo/pull/632 Alas, the CI check failed for some reason I don't understand. :-/ Happy New Year!

Re: [Pharo-dev] Replacement for deprected MultiByteFileStream?

by Bernhard Pieber

Hi Sven, Thanks for the answer. This is exactly what I was looking for. And it is great that there is also documentation. However, ZnCharacterReadStream does not implement #upToAll:. The implementation from PositionableStream cannot easily be borrowed because there seems to be no way to reset the position. Is there a plan to support the most commonly used messages from the normal streams?

Hi Stef, Thank you for your answer pointing me to the ZnCharacter...Stream. This seems to be meant as the replacement I was looking for. I will have a closer look.

Re: [Pharo-dev] Replacement for deprected MultiByteFileStream?

by Bernhard Pieber

Hi Denis, Thank you for your answer. However, setting the UTF8TextConverter did not help because of a bug in upToAll:. I created a pull request to fix it: https://github.com/pharo-project/pharo/pull/632 I am afraid the CI failed for some reason I don't understand. :-/ The UTF8TextConverter was set by default, by the way.
