is there a refactoring to combine two classes in a heirarchy?

I'd like to combine a class and its subclass, adopting all methods from the subclass. Is there a refactoring rule that will do that?

what is wrong here. Tests are green but the outcome with real code is much to high

hello I have this code hasReachedBasement: aFloor Â Â Â "comment stating purpose of message" Â Â Â ^ aFloor = -1 initialize Â Â Â "comment stating purpose of message" Â Â Â super initialize. Â Â Â position := 1. Â Â Â floor := 0 moveFloorDown: aFloor Â Â Â "comment stating purpose of message" Â Â Â ^ floor := aFloor - 1 moveFloorUp: aFloor Â Â Â "comment stating purpose of message" Â Â Â ^ floor := aFloor + 1 reachedBasement: input2 Â Â Â input2 Â Â Â Â Â Â withIndexDo: [ :element :index | Â Â Â Â Â Â Â Â Â element = $( Â Â Â Â Â Â Â Â Â Â Â Â ifTrue: [ self moveFloorUp: floor ] Â Â Â Â Â Â Â Â Â Â Â Â ifFalse: [ self moveFloorDown: floor ]. Â Â Â Â Â Â Â Â Â (self hasReachedBasement: floor) Â Â Â Â Â Â Â Â Â Â Â Â ifTrue: [ position := index ] ]. Â Â Â position ifNotNil: [ ^ position ] This works very fine with test input given by the challenge but as soon as I do it with this : https://gist.github.com/RoelofWobben/3be69976a6dd3531f01558b0ac563556 I see as answer : 6111 where I expect to see 1797 Anyone who can see what I did wrong ?

I'm trying to load NeoCSV and I'm running into all kinds of problems. First, Catalog Browser will not install it â it fails silently. Second, the following fails with "Could not resolve: Neo-CSV-Core in '/home/richard/pharo blah blah blah": Gofer it smalltalkhubUser: 'SvenVanCaekenberghe' project: 'Neo'; configurationOf: 'NeoCSV'; loadStable. What am I missing? -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

The library was written before that convention was established. Currently it is UDBCSQLite3Library (subclassing Object) and its #library says this: library Smalltalk os isMacOS ifTrue: [ ^ #sqlite3 ]. ^ 'sqlite3' This worked before as I had used it with Pharo 5 when my Mac was on El Capitan and Sierra. The Mac is now on High Sierra. Testing... Ok, the system-supplied library is named libsqlite3.0.dylib. After some experimentation, copying/renaming said library works: % cp -p /usr/lib/libsqlite3.0.dylib % ~/Pharo.app/Contents/MacOS/Plugins/libsqlite3.dylib Now 64-bit Pharo 60543 finds the dylib, the SQLite tests run and pass. I also tested keeping the '3.0' in the dylib file name, modifying the #library method accordingly, and evaluating 'UDBCSQLite3Library reset' to clear the singleton class variable. I've not run into this situation before because I've always used my own custom SQLite shared library that includes JSON, FTS etc extensions. For good measure I also ran the Glorp tests and got 891 run, 890 passes, 1 error. The error is due to my changing SQLite's boolean handling, see https://www.samadhiweb.com/blog/2018.05.20.sqlite.boolean.html The test error has been fixed for Pharo 7. Not yet back-ported for Pharo 6. To load GlorpSQLite for Pharo 7, use the Catalog Browser, or, equivalently, load from my repo: Metacello new repository: 'github://PierceNg/glorp-sqlite3:pharo7'; baseline: 'GlorpSQLite'; load. > spatialite Cool! Please let me know how this goes. Back in Pharo 4's Native Boost days, NBSQLite as it was called then supported both SQLite and SQLcipher. I had experimented with loading libsqlcipher3 from UDBCSQLcipher3Library, which subclasses UDBCSQLite3Library, and IIRC also via some class variable in UDBCSQLite3Library determining which shared library to load. Torsten Bergmann kindly ported NBSQLite to UFFI. The SQLcipher part is still on my to-do list, and I am also interested to have (Glorp|UDBC)SQLite load Spatialite (and maybe even libspatialitecipher) cleanly. Pierce

GlorpSQLite not finding sqlite library on Mac
by Todd Blanchard Dec. 16, 2018

Dec. 16, 2018

I loaded up Glorp SQLite using Metacello new repository: 'github://pharo-rdbms/glorp-sqlite3'; baseline: 'GlorpSQLite'; load. This seems to be the only way to get SQLite support? There is no standalone UFFI library? Not that I have a problem with it, I know and like GLORP. Then I ran the basic UDBCSQLite tests and they all fail with 'External module not found'. I'm on MacOS Mojave. I presume this means that the sqlite library was not found but the best I can find is a method #library that returns #sqlite I want to use a homebrew installed version sqlite (technically, I want to use spatialite which is an extended version with GIS extensions). Reading the well written https://files.pharo.org/books-pdfs/booklet-uFFI/UFFIDRAFT.pdf I gather that I should subclass FFILibrary to make a SQLiteLibrary and have UDBCSQLite class that implements #macModuleName to return '/usr/local/Cellar/libspatialite/4.3.0a_6/libspatialite.dylib'?

chooseExistingFileReference:extensions:path:preview returning wrong FileReference?
by Arturo Zambrano Dec. 16, 2018

Dec. 16, 2018

Hi All, I'm replacing a deprecated call by this: UIManager default chooseExistingFileReference:extensions:path:preview:. The returned fileRefence does not point the actual file selected by the user (if the file was chosen navigating to other directories than the default). For example: UIManager default chooseExistingFileReference:'Title' extensions:#('pdf') path: './' preview: nil [image: image.png] Inspect the result: [image: image.png] It seems to be a bug, or maybe there is any other way to call the dialog. Any pointer is welcome. TIA
