Odd literal in metaclasses methods

by Henrik Nergaard

Every method implemented in the class side includes a literal: "nil->theMetaClass". Object class methods collect: [ :cm | cm literals last ]. What is it used for? Best regards, Henrik

Epicea user experience report

by Ben Coman

1. Created fresh Pharo image (build 60269) 2. Opened World > Tools > Epicea > All changes Points for discussion... a. How many submenu items are expected for Epicea? Can we push the current ones up so the Tools menu remains a flat menu. b. Do we need the two current menu items? "Current session" is encompassed by "All changes"? What expectations do people have of how often they'll use the former rather than the latter? c. When people move from Pharo 5 to Pharo 6 and in a panic want to "recover changes" for a crashed image, they'll be looking for that familiar feature name, not a new app name. Could the app name be left out or placed in brackets "Changes (Epicea)". btw, the interface looks really slick! nice work. 3. Opened World > System Browser. 4. Added package AAA All Changes window - no dynamic change. On <refresh>, still no change, i.e. no sessions #New All Changes window - not visible, no sessions. 5. Added class AA. All Changes window - no dynamic change. On <refresh>, shows new session with AAA & AA. 5. Added method... AA>a ^'something' Prompted for author, entered 'BenComan' All Changes window with session selected - dynamic update showing AA>>a. 6. Added package BBB. All Changes window - no dynamic update. On <refresh>, BBB still not visible in session. 7. Added class A to package AAA. All Changes window - dynamic update showing A. On <refresh>, BBB still not visible in session. 8. Added class BB to package BBB. All Changes window - dynamic update showing BBB & BB. a. Package creation event seems not handled properly, being only pushed through when a class is created in it. b. Since there is a dynamic update for class and method modifications, could the session creation also dynamically update it UI. ----------- 9. Killed the vm from command line $ ps -ef | grep pharo $ kill 29349 Restarted Pharo image 10. World > Tools > Epica > All changes. Authorship is inconsistent: * AAA and AA have blank author * AA>>a, A, BBB, B have author 'BenComan'. a. I understand this follows on from Author not being requested until the first method was defined. Did the old changes track the author of packages and classes at all? b. Since Epicea can track package and class authors, can we trigger the author prompt earlier for them? 11. Selected all previous changes AAA, AA, AA>>a, A, BBB, BB and did <Apply Changes>. Prompted for author. Entered 'DrWho' Existing All Changes window - no change New All Changes window - shows new session with all six changes. Authorship is a little inconsistent: * AAA and AA have author 'Unknown'. * AA>>a, A, BBB, B have blank author. 12. Killed the vm from command line $ ps -ef | grep pharo $ kill 30696 Restarted Pharo image 13. World > Tools > Epica > All changes. Authorship is a little inconsistent: First session * AAA and AA have blank author * AA>>a, A, BBB, B have author 'BenComan'. Second session * AAA and AA have blank author * AA>>a, A, BBB, B have author 'DrWho'. a. Epicea changes are reapplied as the current author. This seems a semantic change from Pharo 5 where changes were reapplied as their original author. Is this accidental or by design? Can we have some community discussion on this point (I don't remember seeing any)? cheers -ben P.S. I'll wait to see what arises out of discussion before creating any issues.

Image Distributions [was:Re: Mocks are missing in Pharo (from thread OSProcess is missing)}

by phil＠highoctane.be

Having them in image can indeed be useful. I am testing against REST backends, and well, this is a destructive test to say the least. Not easy to replay as much as I want. I hope that with the Bootstrap we'll be able to have a set of "Batteries Included" distributions. Kind of like we have Moose today, which I like very much as I do not have to load parts from all over the place. On http://tcl.tk there are also a number of such distributions: * the "Batteries Included" ActiveTcl (http://www.activestate.com/activetcl) with its various support levels [which would be good to emulate for the Pharo Pro business proposition] * TclKit / StarKits concept (http://wiki.tcl.tk/52) TclKit is a BaseKit. See http://wiki.tcl.tk/15985 for a table of kits and their supported features. * Build your own from sources. TclKit allows one to build special kit, using a command line tool, similar to what we discuss for loading packages easily. http://wiki.tcl.tk/10558 We do have an image and the TclKit has a VFS (Virtual File System) bundling everything in a single file. So, basically, one runs things with tclkit hello.kit. Quite reminiscent of pharo Pharo.image I'd say. Question 1: Which top 5 packages/configurations would you find useful to have available in a distribution? 1- 2- 3- 4- 5- Question 2: What do you consider to be the top 3 use cases of a Pharo Distribution for your own use? 1- 2- 3- Best, Phil ` On Fri, Oct 28, 2016 at 8:36 PM, Denis Kudriashov <dionisiydk(a)gmail.com> wrote: > > 2016-10-28 18:58 GMT+02:00 Guillermo Polito <guillermopolito(a)gmail.com>: > >> No, please, kernel test should have the fewer dependencies as possible! >> > I would say this dependency is needed. > >> And again i'll hold my position: whoever wants to load it can do it. >> There is no need to put it there by default. >> > Do you know how much easier it would be to design and test FileSystem with > mocks.
