The system tests (duh) for these are really clear. it's generally better to use becomeForward: unless you have a really good reason to use become: and it's generally better to use anything other than becomeForward: if you can. It's what dubya would call "the nukular opshin"

Check out the comments. But a basic example would be... | a b | a := 'foo'. b := 'foobar'. a becomeForward: b. "a = 'foobar' b = 'foobar'" | a b | a := 'foo'. b := 'foobar'. a become: b. "a = 'foobar' b = 'foo'"

Finding all references to an object

I have an object, which I want to replace with a new object everywhere it exists in the system. How do I do that? Thanks.

I treat workspace in same way - for "fire and forget" coding. So, personally, i don't feel much need for improving it and introducing more than it has.

You should have a look at TreeMorph and friends. I'm sure that you can build a leo based system. The timeProfiler is also an example of how to use the TreeMorph Stef On Aug 2, 2011, at 7:52 PM, Offray Vladimir Luna CÃ¡rdenas wrote: > Hi all, > > > I'm reading with great joy, various pharo/smalltalk related books to get a glimpse of what is available.

Re: [Pharo-users] Tree-like workspace

by Benjamin

It's not really hard to do, but I do not really get why it's interesting to have such a behavior I mean, personally, when I use workspace, it's for junk programming (it write code quickly, test it) So usually, I test my code in a workspace before putting it into a method (or it was just for test, and I do not care anymore). But maybe you do not use the workspace the same way ;) Ben On Aug 2, 2011, at 9:52 PM, Ted F.A. van Gaalen wrote: > Hi there > > Well, perhaps you like this idea > (ideas are easier that programming, are they? :o) > > what about a workspace with > on the left a tree pane > with in the tree: saved workspaces > grouped under workspace "categories" > > e.g. > > aWorkspaceTree > +-aWorkspaceCategory > - aSavedWorkspace > - anotherSavedworkspace > +-yetAnotherWorkSpaceCategory > -yetAnotherSavedWorkspace > .. > + > > Greetings > Ted > > > > On Tue, Aug 2, 2011 at 8:25 PM, Benjamin > <benjamin.vanryseghem.pharo(a)gmail.com> wrote: >> >> On Aug 2, 2011, at 8:04 PM, Igor Stasenko wrote: >> >> On 2 August 2011 19:52, Offray Vladimir Luna CÃ¡rdenas <offray(a)riseup.net> >> wrote: >> >> Hi all, >> >> >> I'm reading with great joy, various pharo/smalltalk related books to get a >> >> glimpse of what is available.

Hi there Well, perhaps you like this idea (ideas are easier that programming, are they? :o) what about a workspace with on the left a tree pane with in the tree: saved workspaces grouped under workspace "categories" e.g. aWorkspaceTree +-aWorkspaceCategory - aSavedWorkspace - anotherSavedworkspace +-yetAnotherWorkSpaceCategory -yetAnotherSavedWorkspace .. + Greetings Ted On Tue, Aug 2, 2011 at 8:25 PM, Benjamin <benjamin.vanryseghem.pharo(a)gmail.com> wrote: > > On Aug 2, 2011, at 8:04 PM, Igor Stasenko wrote: > > On 2 August 2011 19:52, Offray Vladimir Luna CÃ¡rdenas <offray(a)riseup.net> > wrote: > > Hi all, > > > I'm reading with great joy, various pharo/smalltalk related books to get a > > glimpse of what is available.
