Re: [Pharo-users] Can I create a personal slice?

by Benjamin

A slice is basically just a set of mcz files So there is no problem at all to use slices for your personal projects :) Ben On 10 Aug 2014, at 23:24, Tim Mackinnon <tim(a)testit.works> wrote: > I will make a not to try Versioneer (although the image I am using is the one PharoLauncher is built in, which is 3.0). > > Anyway - I did try making a slice with bug number 0, and my own description, and it let me create one and save it in my own repository.

How do I trace through implementors in Pharo?

by Tim Mackinnon

As I relearn/learn how to use Pharo, Iâm struck by some of the excellent changes and confounded by some of the simple things that boggle me. So, I wanted to follow a path through some message sends - the use of #alert:title: in UIManager specifically. So I browser UIManager, find the method (its subclassResponsiblity) - so I find other implementers (cmd+b, cmd+m) - (Iâm really liking that there are more keystrokes in newer Pharoâs but not liking that the same operations donât have the same bindings in different windows - e.g. in the debugger - its not this!!) Anyway - this gives me an implementors window on TEasilyThemed - great! In the source, there is another msg send - ^self alert:title:configure: So I want to follow its implementers - I hi light the source and cmd+b,cmd+m does nothing? hmmm - right click there and the context menu doesnât have an obvious way - until I spot (Extended Searchâ¦) [which by the way should be shown as a submenu - like it does in the SystemBrowser). In this menu there is âimplementers of itâ - however this does nothing? (this is in both Pharo 3.0 and Pharo 4.0) So how do you trace through method calls? Am I doing something wrong - or has this been broken for a long time? Tim

Re: [Pharo-users] Can I create a personal slice?

by Tim Mackinnon

I will make a not to try Versioneer (although the image I am using is the one PharoLauncher is built in, which is 3.0). Anyway - I did try making a slice with bug number 0, and my own description, and it let me create one and save it in my own repository. Iâm not sure if there are any bad ramifications to this - but it looks fine. Would be interesting if anyone could comment on this (and I will check out Versioneer - although it still sounds like overkill for some temporary work I just want to version together).

Re: [Pharo-users] Categorise method defaults?

by phil＠highoctane.be

I am interested in that categorizer, especially to tweak it to my own patterns of use. Where is it? Will it work in 3.0? (As 3.0 is the release we can use for production code). Phil â

Re: [Pharo-users] Categorise method defaults?

by stepharo

It is just a glitch. I worked on a better categoriser and it requires one or two days of polishing to integrate it. If you want to help just ask.

Re: [Pharo-users] The tedious split between class and instance?

by Esteban Lorenzano

+1 it would be really useful to have a refactoring âmake creator with instance varsâ, to allow you to pick inst vars and do something like: Blah class>>children: aCollection ^ self basicNew initializeChildren: aCollection; yourself Blah>>initializeChildren: aCollection children := aCollection. self initialize. that would solve all the problem and would be also a nice way to promote a convention on how to do the creation properly :) Esteban On 09 Aug 2014, at 16:29, Tim Mackinnon <tim(a)testit.works> wrote: > The more I use Pharo again - the more it strikes me how tedious it is to have to flip between instance and class side definitions. > > For example - if I create a new class with an instance variable, and then in my class constructor method decide that it would be handy to do: > > ^self new children: items; yourself > > But I donât yet have the #children: method - if I select the create accessors refactoring (while still looking at my class method) - it does nothing because I have an instance variable not a class variable.

Re: [Pharo-users] Can I create a personal slice?

by stepharo

A slice is just a normal package with depend packages. You can also put a dummy number and commit locally to your local cache.
