Re: [Pharo-users] Iceberg loading a Tonel package migrated using SETT

by Guillermo Polito

Hi Esteban, It seems like a bug in Iceberg. If you click on debug, youâll see that although youâve said the project is in tonel format, itâs trying to use a Filetree reader This is due to some missing metadata in the commit (iceberg is relying on commit information there and not working copy information). There is however a simple workaround. If you click in the commit button youâll see that Iceberg tries to create and commit the missing files: If you commit those files, then youâll be able to load your packages.

Iceberg loading a Tonel package migrated using SETT

by Esteban Maringolo

Hi, I'm trying to load a package from a Tonel repository[1] that was created using SETT[2]. The structure seems fine, but when I try to load a package, I'm getting the message saying that there is no version for the package in the current commit (which seems wrong at least to the naked eye). Eg. [image: image.png] Any idea of how to fix it? Regards! [1] https://github.com/eMaringolo/rbac/tree/master/sources/ [2] https://github.com/gemtalk/sett Esteban A. Maringolo

SETT Commit per bundle/package

by Esteban Maringolo

Hi, I don't know if anybody is using SETT to migrate from VW's Store to a Tonel repository, but I'm trying to pull back to Pharo a few packages I moved to VW and continued to maintain there. I don't understand why SETT creates a commit on a "per pundle" (package/bundle) basis. What would be the approach to get a lot of packages working together? E.g. MyPackage-Core, MyPackage-Glorp, MyPackage-Tests, etc. Should MyPackage be a Bundle instead? Regards, Esteban A. Maringolo

Re: [Pharo-users] How to visit over packages, classes, methods (all types)

by Tim Mackinnon

If you have any thoughts on direction, I could take a look - I did the âdirtyâ and reimplemented the methods like everyone elseâ¦ but it really felt like I shouldnât have had toâ¦ So my code looked a bit like this (where I should have used some sort of visitor with my stream instantiated, or maybe I could pass through some block, I think) (exercise solutionClasses asSortedCollection: [ :a :b | a name <= b name ]) do: [ :class | (exercise exercisePackage extendsClass: class) ifTrue: [ class exPrintOutExtensionsFor: exercise exercisePackage on: s ] ifFalse: [ class exPrintOutOn: s ] ] ]. And then in ClassDescription I had methods like this (noticed I need to visit the definition, the comments, the categories for class and instance etc.: exPrintOutOn: aWriteStream "Print a description of the receiver on aWriteStream." aWriteStream nextPutAll: '"-- #', self name, ' (class) --"'; cr; cr; nextPutAll: self definition; nextPut: $.; cr; cr. self hasComment ifTrue: [ aWriteStream nextPut: $". self comment trimBoth encodeDoublingDoubleQuotesOn: aWriteStream. aWriteStream nextPut: $"; cr; cr ]. self exPrintOutCategoriesFor: self class on: aWriteStream. self exPrintOutCategoriesFor: self on: aWriteStream > On 13 Jun 2019, at 08:26, Marcus Denker <marcus.denker(a)inria.fr> wrote: > > > >> On 19 May 2019, at 19:23, Tim Mackinnon <tim(a)testit.works> wrote: >> >> Hi - is there a way to iterate over all the code in a package (or class or baseline) in a generic way (to pretty print out class definitions, and methods - including extensions ). >> >> I was kind of hoping that with TonelWriter and Fileout and Critics that we would have a generic visitor mechanism but it seems that all of them just implemented it again - which misses a big opportunity for refactoring so that when you want to reason/print/manipulate code - it would be more straight forward. >> >> Is there anything/anyone addressing this ?

For those interested in reading about progress on my project and some topics connected to it, here is a link: https://pharokeepers.github.io/ As I mentioned before, Smiljana and I, are posting to the same blog, therefore each post is tagged with the writer`s name.

Re: [Pharo-users] Autocompletion

by eftomi

I found the cause - I created the #buttonBad accessing methods with code (re)factoring (generate accessors), and in this case the accessors are made in this fashion: CustomerSatisfaction >> buttonBad: *anObject *buttonBad := *anObject *It's better to use CustomerSatisfaction >> buttonBad: *aComposablePresenterClass *buttonBad := *aComposablePresenterClass *as this method is doing: ComposablePresenter >> instantiate: aComposablePresenterClass "Instantiate a ComposablePresenter subclass and set its instance owner" ^ aComposablePresenterClass owner: self To find the cause, I used the debugger extensively and found the core logic in ECInstVarTypeGuesser >> perform method - it was quite an exercise!

Re: [Pharo-users] Can I code a web browser in a Pharo GUI window (Morphic or other)?

by Arie van Wingerden

At this time I'd say that PharoJS would probably my first choice to check out for such project in the future. Given my Pharo n00bness however I have decided to stick with C# for this project for now to avoid (too) long implementation times. But I'll definitely dive into the options you tell me about, specifically PharoJS.

Issues with build: 160, commit: b84a1e1 of the Pharo 7.0.3 image?

by Alejandro Fernandez

Hi, I just launched a new Pharo 7.0 - 32bit (stable) from the pharo launcher. Got back an image from build: 160, commit: b84a1e1 First issue I noticed was a broken (?) component in the Wellcome screen (red block with yelllow border and diagonals). Then, after insalling Seaside and trying to add a new adaptor (via the Seaside launcher), an instance of MenuItemPresenter did not understand #isEnabled. No of these issues are present in a clean image obtained with the zeroconf script (build: 158, commit: 0903ade image). Is anyone else experiencing the same problem? Do templates update automatically when a new build is available? Yours, Alejandro
