Font resources not flushed on session
by ducasse March 18, 2019

March 18, 2019

Hi I tried to open an image saved by damien on Mojave. I got the following fatal error. After fighting I could by chance disable and reenable the freetype pluggin and it worked. I think that the font cache was not flushed on something like that. Stef

Esteban's ChangeLog week of 11 March 2019
by estebanlm＠gmail.com March 18, 2019

March 18, 2019

Hello! This is my weekly ChangeLog, from 11 March 2019 to 17 March 2019. You can see it in a better format by going here: http://log.smallworks.eu/web/search?from=11/3/2019&to=17/3/2019 ChangeLog ========= 14 March 2019: -------------- * I've been working on context menus for Spec 2. This seems like an easy task... until you see how broken it was in the previous version. In fact, in older Spec menus were inexistent. Or better: the abstraction for menus were inexistent, and instead it was just a simple exposition (at Spec level) of the Morphic menu infrastructure (which itself is not very friendly). So... I needed to reimplement everything. ... and a way to test it :( Now, I want to consider the Menu interface more in detail, since today is not very clear. Look how a Menu Bar needs to be made: ---- MenuBarPresenter new addGroup: [ :group | group addItem: [ :item | item name: 'Something 1'; action: [ "doSomething"] ]; addMenu: [ :item | item name: 'Something 2'; action: [ "doSomething"] ] ]; yourself ---- which doesn't seems to be the best approach. (Anyway, I'm not changing that just now... but I'm reflecting on it, certainly) 13 March 2019: -------------- * I made a pause of my Spec 2 current work to make a fix that was pending since some time now and it was needed to easy the migration of some projects (and its usage in windows): This [PR](https://github.com/pharo-vcs/iceberg/pull/1213) will fix [tonel issue 74](https://github.com/pharo-vcs/tonel/issues/74) cheers!

OSProcess for Pharo 7
by Max Leske March 18, 2019

March 18, 2019

Hi all, Pharo 7 no longer includes #ifNotNilDo:, meaning that OSProcess loading fails. I volunteer to update OSProcess for Pharo 7 but I need someone to tell me what the expected workflow is. AFAICT, we've simply copied the current ConfigurationOf to the MetaRepoForXX in the past without making any changes specific to Pharo. That will not work this time. So, should I create a new version of OSProcess for all platforms, where #ifNotNilDo: has been replaced with #ifNotNil:? Or should I add a compatibility package for Pharo? Or something else? Cheers, Max

ZnBufferedReadStream and #upToAll:
by Eric Gade March 18, 2019

March 18, 2019

Hi all, Was there a conscious decision not to include the #upToAll: method onZnBufferedReadStream?. This method is really useful for parsing files -- finding sub-patterns of bytes, etc. Perhaps #upToAll: is not the idiomatic way to do this, but I found it very useful to use in the plain old ReadStream classes. Sub-question: if I wanted to implement something like this and make a PR, would I be submitting to the Pharo dev repository or the Zinc repository? -- Eric
