recovering non-ascii code in 6.1
by Siemen Baader Nov. 15, 2019

Nov. 15, 2019

Hi, I have a broken 6.1 image and uncommited code with non-ascii characters in it. When I drag the .changes file onto a new 6.1 image it won't import due to the non-ascii code, but I can rename the .changes file so it matches the new image's filename and import individual code changes (also with non-chars) with Wold Menu -> Tools -> Code Changes. Can I somehow file in the whole .changes file at once to end with the same code state as in the original image? -- Siemen

Presenter initialization
by Kasper Ãsterbye Nov. 14, 2019

Nov. 14, 2019

Cheers, I want to make a Spec Presenter which can show rendered pillar. I have the necessary code to transform a pillar string document into Text with fonts and stuff. My problem is how to make the Presenter. To get moving I did not want to make a wysiwyg editor, but a simple two-mode thing. It either shows the rendered text or the pillar source. When I looked at the Spec components it seems a reasonable approach to make it a subclass of SpTextPresenter, to get all the editing of the source for free. Now after having made this subclass, PillarTextPreseanter, I realize it would be nice if I could tell the difference between rendering mode and editing mode. I thought it would be simple to use a slightly different background color for the editor in rendering mode. And here is the problem: - If I override "initialize" to change the color (self color: MyColor), it has no effect - If I override the "initializeWidgets" to change the color, it has no effect Flopping through the implementation of "openWithSpec", I find that I can implement an "announceDisplayed" method, and if I set the color in that method it does indeed keep the color. I have no idea how I should have found this out (except spending a Thursday morning on it), I am not sure it is the best solution. I have no idea why the other two methods do not work. At times I must admit I am truely baffled by the complexity of it all. Best, Kasper

Hello, IM doing now this book to understand better the OOP side of Pharo : https://books.pharo.org/learning-oop/ im now at the last challenge of the network-simulator and im stuck. I want to test if the send package is really send back uppercase but I cannot find a way to see the contents of the package in my test I have made so far : https://github.com/RoelofWobben/network/blob/master/NetworkSimulator-Tests/… Can anyone give me a hint how I can achieve what I want ?

Re: [Pharo-users] Was there some force push to Roassal?

It's really not recommended to use it on a used project in any case. Even if it's to win some space, it's not worth it. For the .git folder, in general when they grow too much it's often only local. The .git folder of my local clone of roassal is 384B and I have it since month and it is up to date. The "easy" solution is to clone again. Most of the time when I have a clone that is too big, the command `git gc` is enough to shrink it. > Cheers, > Alexandre > > > -- Cyril Ferlicot https://ferlicot.fr

Google found me a way to list large objects... ``` git rev-list --objects --all \ | git cat-file --batch-check='%(objecttype) %(objectname) %(objectsize) %(rest)' \ | sed -n 's/^blob //p' \ | sort --numeric-sort --key=2 \ | cut -c 1-12,41- \ | $(command -v gnumfmt || echo numfmt) --field=2 --to=iec-i --suffix=B --padding=7 --round=nearest \ > ../list.txt ``` The largest file entry was... e0c5f0885bac 432KiB src/Roassal2/ RTRoassalExample.class.st That file is no longer in the repo, but... $ grep RTRoassalExample.class.st ../list.txt | wc -l ==> 158 and 158 * 432K ==> 68M Found the commit with that blob to examine... $ git log --all --pretty=format:%H -- src/Roassal2/RTRoassalExample.class.st | xargs -n1 -I% sh -c "git ls-tree % -- src/Roassal2/ RTRoassalExample.class.st | grep -q e0c5f0885bac && echo %" ==> a7753aef2a9f14cf5c84da83b8ebff7e4e35f0e9 $ git checkout a7753aef2a9f14cf5c84da83b8ebff7e4e35f0e9 $ vi src/Roassal2/RTRoassalExample.class.st and I see the culprit is icons being encoded directly in the class... { #category : #icons } RTRoassalExample >> exampleAligningGroupsIcon [ ^ 'iVBORw0KGgoAAAANSUhEUgAAAGQAAABkCAYAAABw4pVUAAAICElEQVR4XuWaWWhUVxjHI27Q 1oJttfjUusQHQdE+uIFUJYIVBC1VrDv6oKDUd5fGKK3RRgkRFfelaKvR1rpS7YbGFrUWcaHF msYsNMaJSWa9SWbmf3v+9/YmM5M7zj5J/P4wzGQyc+855/edbzuTo+vy1ZWUI38J5AORL/lA 5AORL/lA5AORL/lA5AORL/lA5AORL/lA5Es+EPlA5Es+EPlA5Es+EPlA5Es+EPlA5Es+EPmS D0Q+EPmSD0Q+EPmSD0Q+EPmSD0Q+EPmSD0S+5AORD0S+5AORD0S+5AORD6QratMmoLkZCH3v ...etc One way to reduce those historical file sizes would be running git-filter with an automated way to extract those icons to separate files and add code to load them. Seems hard. Following another path of investigation led me first to to "Git Compression of Blobs and Packfiles" https://gist.github.com/matthewmccullough/2695758 So trying... $ git gc --aggressive $ du -sh . ==> 18M https://stackoverflow.com/questions/28720151/git-gc-aggressive-vs-git-repack led me to the same job being done by... $ git repack -a -d -f --depth=10 --window=250 $ du -sh . ==> 18M My understanding is that this is safe and doesn't affect the commit history. However its just a local result. A few things I read gives the feeling that pushing from that repacked repo won't change anything on the server since it only sends a diff to the server, which then repacks in its own time. Perhaps the only way is ask GIthub Support if they can repack it. https://help.github.com/en/github/working-with-github-support/submitting-a-… cheers -ben

Was there some force push to Roassal?
by Cyril Ferlicot D. Nov. 10, 2019

Nov. 10, 2019

Hi, Since there is no release for roassal I have projects referencing a SHA of a stable Roassal 2 version. I see in my projects that the roassal SHA targeted was c1da8614c951008ea501f126ef3ccf25d73580ac but now I cannot find it in the history of roassal and my projects are failing. So I am wondering if someone forced pushed on Roassal 2? And if yes, what is the reason? Because of this, all the released of the projects depending on this version of roassal will never work again. Please, please, do not use destructive operations on projects that are intended to be used :( -- Cyril Ferlicot https://ferlicot.fr

Script to download specific Pharo version
by BrunoBB Nov. 4, 2019

Nov. 4, 2019

Hi, We have a Linux script to build our image and was working well until recently. It seems that the failure is related (not confirmed yet) to https://github.com/pharo-project/pharo/issues/4764 Becuase it fail to load Seaside into the Pharo image. Is there any way to download a specific build or version like ? wget -q -O- https://get.pharo.org/64/703 | bash In this case to download Pharo 7.03 We want to try our script with different Pharo versions, because "wget -O- https://get.pharo.org/64 | bash" it download the latest. regards, bruno -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
