Re: [Pharo-project] Issue 3498 in pharo: remove:ifAbsent: in linked list leads to interruption/sync problems

Comment #6 on issue 3498 by rydier: remove:ifAbsent: in linked list leads to interruption/sync problems http://code.google.com/p/pharo/issues/detail?id=3498 For the record, it was rewritten to accept regular objects as well as links as arguments (in which case a ValueLink for the object is created with add/found and removed with remove) removeLink:ifAbsent: is exactly the same as remove:ifAbsent: in Squeak The reason I did not add the ifAbsent: block to the removeLink: call in new remove:ifAbsent: was pure ignorance, I was not aware LinkedLists methods were supposed to be thread-safe, for instance add:after: is not, neither in Pharo nor Squeak. The version currently in Pharo (without ifAbsent:) is perfectly valid if thread-safeness is not a criterion.

If I understand correctly what + and , mean I like them a lot. As I understand the difference is: - with + you to compose keys (for example, Ctrl+s accepts in Smalltalk) - with , you concatenate key sequences for example (for example, Ctrl+x , s saves in Emacs) Cheers, Doru > Maybe a little help somewhere would be fine. > Ahhh and what about letting you type something and recognize the shortcut instead of writing it? heheh this is a good one ;) > > Mmm, I can take what Alain said and this, and have a nice thing ;) > > > cheers > > mariano > > > On Fri, Dec 31, 2010 at 12:28 AM, Guillermo Polito <guillermopolito(a)gmail.com> wrote: > Hi, I would like to discuss the UI for shortcuts and not to impose it :).
