Esteban's ChangeLog week of 2 October 2017

by estebanlm＠gmail.com

Hello! This is my weekly ChangeLog, from 2 October 2017 to 8 October 2017. You can see it in a better format by going here: http://log.smallworks.eu/web/search?from=2/10/2017&to=8/10/2017 ChangeLog ========= 6 October 2017: --------------- * I released [Iceberg 0.6](https://github.com/pharo-vcs/iceberg/releases/tag/v0.6) ! Most important part of the inclusion of [tonel](https://github.com/pharo-vcs/tonel) as the default file format, but there are a lot of small changes and bugfixes. It will be integrated soon into Pharo 7.0a and the [README](https://github.com/pharo-vcs/iceberg/blob/master/README.md) has instructions to explain you how to update Pharo 6.1 images. 5 October 2017: --------------- * I've been working on release Iceberg 0.6, and we are almost there... but I decided to restore green tests on travis before moving on. Test have been failing since a lot of time as is moment to get back to appropriate software policies :) 3 October 2017: --------------- * I just submited a PR to fix [case: 18849](https://pharo.fogbugz.com/f/cases/18849) to update Metacello to latest version. This will prepare things to integrate Iceberg 0.6. 2 October 2017: --------------- * Finally, I got latest version of Metacello to work on Pharo correctly. It was hard, but I prevailed :) I will schedule it for integration in Pharo 7 too. cheers! Esteban

Re: [Pharo-dev] Non blurry Pharo 6.1 on Windows 10 and 4K display

by Tim Mackinnon

I wish there was a solution on a Macbook pro - although with Bloc continuing to forge ahead we get closer and closer. I hadnât realised that not only is it blurry when it uses pixel doubling - but you also get a smaller workspace as well. I happened to take a copy of an image and run it on an older MacBook Air and was amazed to see that the workspace only took up 3/4 of the screen on the air, and so I could make it bigger and see more (more clearly as well). Its a problem that we really need to solve universally.

Re: [Pharo-dev] PharoMinimal ?

by Thierry Goubier

Le 08/10/2017 Ã 18:55, Guillermo Polito a Ã©critÂ : > That's still not enough ;) That's close enough for me. > That will work when the loaded package has no dependencies. Otherwise, > imagine projects A and B, and A depending on B's release. every time you > release B you need to release all dependencies... Sort of. If when loading A, A has a correct reference to a stable B release, then that is ok. However, if B is released before A has the time to prepare a compatible version to the latest B, then, yes, that will break, but that also means A isn't properly synchronized with B (which is my point about external projects having to be synchronized). Then A may have in its baseline a check on the last B release known to be compatible... > And, if you use a tag or exact committish to get the Baseline you want > to install, still that baseline needs to point to the exact > tag/committish of it's dependencies. Agreed. You can still, in Metacello scripting, point to two (or more) repositories when loading the baseline (and then Metacello would pick the newest one), but: first, I don't know how to do it from inside a Baseline (dependencies), and, second, if filetree is used, then we loose the ability to tell which one is newest. (*) > Or! If you know the dependencies of your baseline you can explicitly use > a Metacello's lock. I still believe this is an overkill and I'd like to > simplify it, but that's what we have right now. As I said above, it seems possible if you create a level of indirection when fetching the baseline of a dependency. And saying that, I know how to do it. Within the BaselineOf itself.

Re: [Pharo-dev] PharoMinimal ?

by Sven Van Caekenberghe

Hi Pavel, Thanks a lot for the explanation. To summarise: 70-minimal is the one with monticello and metacello in it that can load code via the config handler. I was confused, because that failed for me. Now, first doing $ ./pharo pharo-minimal.image eval 'ZnMimeType initialize' fixed my loading problem. I also did the following because some of my project don't separate tests (I known ;-) $ ./pharo pharo-minimal.image eval --save 'Object subclass: #TestCase' With those fixes I was able to load different projects $ ./pharo pharo-minimal config http://mc.stfx.eu/Neo ConfigurationOfZTimestamp --install=stable $ ./pharo pharo-minimal config http://mc.stfx.eu/Neo ConfigurationOfNeoConsole --install=bleedingEdge The image remains equally fast in startup $ time ./pharo pharo-minimal.image eval ZTimestamp now 2017-10-08T16:55:00Z real 0m0.062s user 0m0.025s sys 0m0.029s And it works perfectly as a server, like $ ./pharo pharo-minimal eval --no-quit 'NeoConsoleTelnetServer new start' & $ telnet localhost 4999 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'.

Connection closed by foreign host. Image size remains ~11Mb. Very nice ! About the class initialisations. Why were they not done already ? You seem to have a list of them, why not make sure they are executed when creating the image ? I guess I could rewrite some of my code to do lazy initialization class side but I should not have to do that, should I ?

Non blurry Pharo 6.1 on Windows 10 and 4K display

by phil＠highoctane.be

Just wanted to say that one can have Pharo on a 4K display without blurry fonts. https://i.imgur.com/FDeLFTN.png This requires to use the settings with Large or Huge fonts. And create a shortcut to Pharo.exe with the following settings in the properties of that shortcut: https://i.imgur.com/7G1sEtz.png There are then other issues showing, namely that tools are opening with default extents that are way too small for a 4K screen. Maybe we should detect that or have a command line switch and update all tools so that the extent is multiplied by that factor. The cursor is also tiny, but maybe VistaCursors can help. So, a Hi-DPI screen on Windows 10 is definitely not an issue. My new laptop has such a screen so, I have got an itch to scratch to get legible and usable things on it. Icons are also too small and some items like Spotter "search" placeholder are not respecting the font sizes of the settings. https://i.imgur.com/lIAwdKx.png Anyway, no blur, yay! Check https://www.digitaltrends.com/computing/how-to-adjust-high-dpi-scaling-in-w… for more on those settings. Check Phil
