Is there an easy way to create a test class in Calypso?
by Tim Mackinnon June 22, 2018

June 22, 2018

Hi - In nautilus there was a handy menu item on a class to jump to its test class (and create it if need by) - Is there any easy way to do this in Calypso? I know it was a simple thing - but I found it did encourage me to write testsâ¦ Tim

Lost in stream
by Hilaire June 22, 2018

June 22, 2018

Hi, I have issue when moving away from the deprecated File API to save PNG image: This fromer code to save file (xml or PNG file): "Â Â Â |streamOnDisk| Â Â Â [streamOnDisk := MultiByteFileStream forceNewFileNamed: (self absolutePath: filename). Â Â Â streamOnDisk nextPutAll: stream contents] ensure: Â Â Â Â Â Â [streamOnDisk close]" and the newer one: Â Â Â (locationÂ asFileReference / filename) binaryWriteStreamDo: [ :fileStream | Â Â Â Â Â Â fileStream nextPutAll: stream contents] The new one produce both wrong XML file and PNG file. The file looks short cuted at the end. The XML document contents itself a chunk of binary data (a bitmap dropped in the drgeo sketch), and the fragility seems to come from there. I already met fragilities with some file when loading older drgeo document, but I have not fully tracked the issue. What is wrong? The enclosed archive contains both files saved with the former and newer methods, both XML and PNG documents. Thanks Hilaire -- Dr. Geo http://drgeo.eu

In Pharo 7 - are the Browsers in any particular order in the new menu?
by Tim Mackinnon June 22, 2018

June 22, 2018

Hi - in the new menu system (which I kind of like, and certainly see the value for new user, but worry about the loss of screen space for advanced users) - is the order of browsers specified for any particular reason? I ask, because the 2 main one System and Playground should both be at the top (in my opinion) but Iâm wondering if its in some specific order? Tim

Voyage-UnQLite hangs on Windows
by Marco HÃ¶rning June 20, 2018

June 20, 2018

I started evaluating Voyage-UnQLite, current Pharo 6.1, Windows 10 installed: Metacello new repository: 'github://pharo-nosql/voyage/mc'; baseline: 'Voyage'; load: 'unqlite tests'. Using latest dll (Aug 10, 2016) https://github.com/pharo-nosql/PunQLite/commits/master/binary/win/unqlite.d… Basic test trying to store and reload a simple object containing a string instance variable Object subclass: #SomeTag instanceVariableNames: 'designation' SomeTag class>>isVoyageRoot ^ true Here's the Testcase code: VoyageTest>>setUp repository := VOUnQLiteRepository on: FileSystem workingDirectory / 'TestDatabase.db'. repository open VoyageTest>>tearDown repository close Running tests now: VoyageTest>>testVoyageUnQLiteStartup self assert: repository isOpen that works, db an be opened and closed. Now trying to store an object.... VoyageTest>>testVoyageUnQLiteWrite | aTag | self assert: SomeTag isVoyageRoot. aTag := SomeTag new designation:'aTag'. repository save: aTag works, if I open a Database (PunQLite) Browser it shows me the entries 'SomeTag' and 'SomeTag_0'. Trying to load the object.... VoyageTest>>testVoyageUnQLiteRead | fetchedTags | fetchedTags := repository selectAll:SomeTag that does not work. System hangs and I get a Testcase timeout with a "TestTookTooMuchTime" exception. the external call in UnQLilteFFI>>array: pArray walk: xWalk data: pUserData does not come back. Any comments or bright ideas what's wrong ? Anybody experience with Voyage-UnQLite on Windows ? Kind Regards from Germany Marco

How to contribute to Calypso when it relies on pharo-core editors?
by Tim Mackinnon June 20, 2018

June 20, 2018

Hi - so in trying to improve the sendersof/implementors of - I thought I had nailed it (and got working what I had done in Pharo 6 for Pharo 7) - but when I loaded my commit into a fresh image I realised that none of the (minor) changes I had made to Calypso had been committed. This is actually quite confusing - and its take me a while to realise that Calypso is a separate project and so when I picked commit on Pharo - this wonât pick up any of the changes in Calypsoâ¦. Arrrgggg So now Iâm guessing that I have to follow the same steps that I followed for loading a pharo repo - for Calypso? But then if I do this - and I propose some fixes to Calypso - how can it work, as it relies on some changes to older pharo core editors that its inserting from? My changes without Calypso will work (they did in V6) - but then how can someone test those in V7 as Calypso is then the default variable. Iâm in a bit of a twist - how can I proceed? Iâd really like to help improve the situation - as its bugged me for years that its a pain looking stuff up quickly (requiring you to highlight just the right stuff for very obvious things) Tim
