Peter, In general, removing from a Collection while iterating through it leads to undefined results. The same is true for adding.

OrderedCollection remove:

by Peter UhnÃ¡k

Hi, I've just run into quite a nasty surprise ~~~~~~~~~~~~~~~~ col := #(1 2 3 4 5) asOrderedCollection. col do: [ :each | col remove: each. ]. col ~~~~~~~~~~~~~~~~ it throws "NotFound: nil not found in OrderedCollection" I tested it also in Pharo3 and there it just silently removed first, third and fifth element. Looking at the implementation of OrderedCollection>>do: it seems that doing what I'm doing is a bad idea. So what shall one do:? col copy do: [...] ? Why can't do: be a bit smarter? Optimization? Thanks, Peter

Re: [Pharo-users] Bytecodes in Nautilus

by ClÃ©ment Bera

Seemingly, UI-wise, it was not good to have a button for the bytecode. As I use it al the time, I reintroduced it in the menu and you can use the shortcut Cmd+b+b, which reportedly was better. In other IDE tools that nautilus you can't see anymore the bytecodes though. 2015-04-01 8:06 GMT-07:00 Sean P. DeNigris <sean(a)clipperadams.com>: > Hmm...

Re: [Pharo-users] Cormas Pharo Port v0.2 available

by Alexandre Bergel

Yes, this is indeed bad. Maybe the GTDebugger team can do something in that respect. Here is a way to reproduce this: Doit: Error signal: âfoobar' Then you get Doiting: Warning signal: 'foobar' Can we have the description of the warning in the debugger header? Would be great!

Re: [Pharo-users] [Pharo-dev] [ANN] New service: The Pharo catalog

Thanks Esteban. Its a worthwhile stopgap until the new service. At a minimum its visibility should encourage developers to supply the required information, so its more complete when the new service arrives. cheers -ben On Thu, Apr 2, 2015 at 12:57 AM, stepharo <stepharo(a)free.fr> wrote: > > > Le 1/4/15 18:07, Laura Risani a Ã©crit : > > Very cool! > This is something i've read many people saying they wanted to have. > I found the quite visibly placed link 'a note to developers' very useful > and will add the explained methods to my projects. > Seems that the existence of #catalogDescription is not as known as the > practice of defining a 'ConfigurationOf' class. > > > Yes because it was an experience I did to understand how/if it was making > sense to add metadata to configuration. > Else versionner would support it. > Now we are changing it so we prefer to invest in the new version. > > Stef > > > > > On Wed, Apr 1, 2015 at 8:11 AM, Esteban Lorenzano <estebanlm(a)gmail.com> > wrote: > >> >> On 01 Apr 2015, at 13:04, Norbert Hartl <norbert(a)hartl.name> wrote: >> >> Cool!
