Re: [Pharo-dev] Do we kill the catalog?

by Torsten Bergmann

Hi Stef, do not worry - I'm fully relaxed. It is you - who suggested to kill the catalog - without having or proposing a suitable alternative yet. If you want to route the thread to talking about "idiots" and "assholes" you go offtopic and I guess I have nothing more to contribute to the discussion. If it was not clear from my writing: I only expressed my wish that we should better improve it instead of killing it. That's all. Because anytime we have a better idea we get more disruptive in what we provide ... and this leads to the unfortunate situation: - that we replace our own stuff with newer ones again and again (which can but must not be good as things get more diverse and complicated over time) - that users have to know how things historically have been progressed to find its way through Pharo (including the terms and tools we use) I would not see this as a rant - but rather a true effect we can spot on many places in our ecosystem already. Long story short: I would vote for the "fix" if the sole other option is to "remove". Bye T. > Gesendet: Samstag, 21.

Well it should not be, not even in older Pharo versions, as long as you use everything correctly.

Hi, I am so looking forward to playing with this (as a user). For various reasons, we are still in Pharo 6.1, but encoding/decoding was always a troublesome issue in Pharo. Thanks a lot!

Calypso zero class refs for TComparable

by Ben Coman

I expected TComparable to be used somewhere in the Image? So I was surprised that with Calypso, right-clicking on TComparable and choosing "Class refs" brought up zero results. Is this expected behaviour? (in 70793) cheers -ben
