Re: [Pharo-dev] #sum:, #detectSum:, #sumNumbers:

by Max Leske

Ok. So while the âdecoratorâ approach looks fantastic it will obviously have its own drawbacks. Discussing this on the mailing list is very tiering, so I suggest that this should be discussed during the next sprint or Pharo days. Since I will not be able to attend either one, can I ask one of you to take responsibility for this? Sven or Doru maybe?

spotter much slower (GTools 3.6)

by Nicolai Hess

since pharo 50524 spotter is much slower. Most probably related to search results from classes with many subclasses Morph / Object / Error / Announcement. For example, search for Announcement and dive into the result for the Announcement class. It takes about ~ 10 seconds to build the result page (instance methods / super instance methods....) Testcase GTSpotterStepTest>>timeClassTest:aClassName [ self basicSearch:aClassName ] timeToRun logCr. "Pharo 50523" timeClassTest:'Announcement' 0:00:00:00.539 timeClassTest:'Morph' 0:00:00:01.448 "Pharo 50524" timeClassTest:'Announcement' 0:00:00:06.936 timeClassTest:'Morph' 0:00:00:49.044 Or open SUnit Testrunner and run tests for package: GT-Tests-Spotter-Scripting nicolai

Awesome work Mariano , I love the documentation. Question : Does your library use the new FFI (Unified FFi) ?
