Pharo 7 file streams guideline

by Pavel Krivanek

Hello, I've prepared a draft of a short document that should help you with the transition to the "new" file streams API in Pharo 7. https://github.com/pavel-krivanek/pharoMaterials/blob/master/Filestreams.MD Pull requests are welcome. Cheers, -- Pavel

Where should I put this statement? In baselineOfSmaCC, or baselineOfGrace? Why? Note that the SmaCC-Reification package is not part of the current normal load for SmaCC â thatâs why I have to specify it separately. Is this declaration saying the opposite? If not, what is it saying? Earlier, you wrote: >> spec package: 'SmaCC-Reification' with: [ spec requires: >> #('SmaCC-Smalltalk-Parser' 'SmaCC-Runtime' 'SmaCC-Java') ] AFAICT this is not necessary because these dependencies are declared in BaselineOfSmaCC. These declarations are the very lines from baselineOfSmaCC that declare these dependencies â arenât they? If I take them out, how will Metacello know that loading SmaCC-Reification requires the three packages listed in the array? Iâm sorry if I sound frustrated â none of this makes any sense to me. There seems to be no documentation other than the very high-level stuff that describes th eoverall purpose of package dependencies â which I think that I understand. Andrew

What you're saying here is load a BaselineOfXyz where Xyz = 'SmaCC-Reification'. In fact you want to load the package. I think you can just change the keyword #basline: to #package:, although SmaCC has a 'Reification' group, which might be better. In any event, if you just want to make sure that the 'SmaCC-Reification' package is loaded when you load SmaCC, then I think what you're after is: spec baseline: 'SmaCC' with: [ spec loads: #('Reification' ) ] I think the above would replace both of your SmaCC-related lines (you can specify multiple entities in to #loads: if needed.

In fact the whole point of Metacello is that you can refer just to the specific entity within a project you want to load and Metacello should take care of bringing along all its dependencies. ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

I think that there may indeed be some brokenness in the way that Pharo uses git, so that the branch spec in the baseline is not always obeyed. So I switched both of the dependencies to be on the same branch (fglr), and for good measure switched my local repo to also be on that branch. > spec > baseline: 'SmaCC' > with: [ spec repository: 'github://apblack/SmaCC:fglr' ]. > spec > baseline: 'SmaCC-Reification' > with: [ spec repository: 'github://apblack/SmaCC:fglr' ]. The result? Nothing changes. I still get a complaint Could not resolve: BaselineOfSmaCC-Reification [BaselineOfSmaCC-Reification] in /Users/black/Development/Pharo/images/Pharo 7.0 SmallGrace 33/pharo-local/package-cache git@github.com:apblack/SmaCC.git[fglr] In the git directory I can see > silverstone: ~/iceberg/apblack/SmaCC$ ls -d SmaCC-Reification.package/ > SmaCC-Reification.package/ > silverstone: ~/iceberg/apblack/SmaCC$ git br > * fglr > ... Is it supposed to be looking for `BaselineOfSmaCC-Reification` rather than for `SmaCC-Reification`? There is no `BaselineOfSmaCC-Reification`, just a `BaselineOfSmaCC` that defines a group called `SmaCC-Refication`. (I did try replacing baseline: âSmaCC-Reificationâ by group: âSmaCC-Reificationâ , but that gave a different error.) Andrew

Grease stream tests failing on Pharo7

by Johan Brichau

Hi, I am taking a look at making Grease and Seaside work correctly on Pharo7. There have been a number of changes to the ReadWriteStream implementation in Pharo that break Grease tests: https://travis-ci.org/SeasideSt/Grease/jobs/406766720 <https://travis-ci.org/SeasideSt/Grease/jobs/406766720> It seems ReadWriteStream is broken: the readLimit is almost always wrong meaning that the stream `atEnd`, `contents` etc.. return wrong values Before I dive into this, I wanted to inquire if anyone is working on this as I cannot seem to find any open cases on this on the issue tracker. cheers Johan

Mac OS X left/right scrolling in Pharo issues

by wyattbiker

Is there a way to disable the mouse left/right side scroll when using the Pharo IDE. It causes unwanted highlights or mouse cursor movements. I think it simulates SHIFT + right/left arrow keys. I am using a Magic Mouse but also the trackpad has same problem. Here in this example, the sidescroll actually scrolls thru the tabs of the Inspector. <http://forum.world.st/file/t369021/Screen_Shot_2018-07-21-1.png> In the browser or playground it moves and highlights randomly. <http://forum.world.st/file/t369021/Screen_Shot_2018-07-21-2.png> -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
