Import a pharo 6 image in pharo 7
by Oswall Verny Arguedas C. Oct. 23, 2019

Oct. 23, 2019

I have a prototype of an application with image persistence made in pharo 6.1. I wanted to export (upgrade) the data (database, objects, collections) of the image and code to Pharo 7. It is possible to perform that operation. Thanks in advance Oswall

Re: [Pharo-users] Glorp + P3 + SQLite

The error you hit was because the package loader was smart enough to notice that there was a version conflict between the version of a subproject already in the image and what the new load instructions were telling it to load. The title of the debugger you pasted in alludes to that fact. So what you need to do is decide what to do when there is a conflict as its tricky for a package manager to figure out what it should do in every case. Metacello includes an instruction #onConflict: which accepts a block. You can write code in the block to decide wether to use the incoming version or the extant version in the image or whatever. e.g. Metacello new repository: 'github://PierceNg/glorp-sqlite3:pharo7'; baseline: 'GlorpSQLite'; onConflict:[:ex | ex allow]; load. would likely get everything to load without issue. Then you'd have to run the tests to see if the version conflict caused problems. Pharo Smalltalk Users mailing list wrote > Nice!

Todd, to load SQLite3 only: Metacello new repository: 'github://astares/Pharo-UDBC/src'; baseline: 'UDBC'; load: 'SQLite' Pierce

Moving pharo
by Kasper Ãsterbye Oct. 22, 2019

Oct. 22, 2019

Today is a big day for some in Denmark. We are moving an old landmark lighthouse 80m inland. https://media.scribblelive.com/2019/10/22/72511d80-c9c1-4a19-b8d8-eec2cad61… I have the feeling it is not that different from moving Pharo. A lot of people working, and progress is slow but steady. About 40sec into it, you see the whole lighthouse. Best, Kasper

Pillar in-image rendering as RichText
by Kasper Ãsterbye Oct. 22, 2019

Oct. 22, 2019

Cheers, Rendering the Pillar markup inside the Pharo image This is work in (early) progress, but I think it is far enough for a "technology preview". <https://github.com/kasperosterbye/PillarRichTextRender/blob/master/README.m…>Goal of the project The goal of the project is to be able to do better in-image documentation. To do this, I am working on several fronts: 1. Rendering more pillar, expecially I would like to get a solution for tables. 2. Rendering github markdown in addition to pillar markdown. This will allow me to pull markdown from git and display it in-image. 3. Giving the "help-system" some love. 4. In-image tools for writing markdown - a markdown editor 5. A design for keeping the mark-down texts seamlessly outside of the image Reg. 1., I can only figure out how to transform a morphic table into an image, and then add that image to the text (not included atm as I find it so ugly a solution). Any other ideas are greatly appreciated. Reg. 2. I am nearly done on this one, at least for the easy aspects (headers, lists, emphasis, code-blocks). Reg 3 and 4. Only loose ideas atm. <https://github.com/kasperosterbye/PillarRichTextRender/blob/master/README.m…>Trying it out Load it using Metacello: Metacello new baseline: 'PillarRichTextRender'; repository: 'github://kasperosterbye/PillarRichTextRender'; load. At the moment it will load the whole of Pillar, but I hope to fix that soon. Once loaded, the class PRRichTextComposer has some examples on the class side.

String concatenation vs. Stream
by Kasper Ãsterbye Oct. 21, 2019

Oct. 21, 2019

This is an old one, and I knew of cause that one should not use #, when you can use streams instead. But that is was this bad to use #, came as a surprise I must say <https://gist.github.com/kasperosterbye/d8c9bd518fba68289c9f129d553ad6b6> Best, Kasper

PharoADO
by eftomi Oct. 21, 2019

Oct. 21, 2019

Dear all, A working prototype of PharoADO is now available at https://github.com/eftomi/pharo-ado. I'd be glad if you can find the time to test it and report your observations to this list or on the GitHub. PRs are welcome and much needed :-) Firstly, I would like to focus on various database data types. When using ADOClient and ADORecordset, the availability of data types heavily depends from PharoWin32/PharoCOM packages, so we have to update both repositories :-) The PharoADO package is not huge after all, since ActiveX Data Objects itself is an abstraction layer and provides much of the needed functionalities by itself. Best wishes, Tomaz -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Strategy for investigating test failures
by PBKResearch Oct. 20, 2019

Oct. 20, 2019

Hello all I have done some experiments, and basically all the questions in my previous mail can be ignored. I think it is all a question of timing, which I sort of understand. Perhaps someone can clarify for me. All my previous tests involved running the whole test suite, to ensure the set-up and tear-down methods were run. As an experiment, I selected the one red method and clicked 'Run Tests'. After about 10 seconds, a halt appeared with the message 'Test took too long'. When I clicked 'Proceed', the green appeared almost immediately. I tried again several times with similar results, although the halt occurred at different places in the code. I went back to my old P6 version and tried running tests on the one method; each time, it ran to green in about 11-12 seconds. So back now to the P7 version; wondered if there is now a setting for permitted test duration. Eventually found it under 'System', default 10 secs. Changed to 15 secs, re-run red test, now comes up green. Re-run whole test suite, all green. So it all comes down to my ignorance of test settings. But Pharo is less than helpful; if you run the whole test suite, there is no way to distinguish a test which failed due to a wrong assertion from one which was terminated for taking too long - or did I miss something?
