Before the thread devolves any further into flames: this thread started because Gerry pointed out some deficiencies in Pharo's toolset. I took umbrage at what I consider to be dismissive remarks. The Pharo folk lack manpower, so I consider it a perfectly valid response for Igor/Stephane/whoever to say "go write it yourself, because we're too busy". So far we've established that there's desire in the community for a REPL-like interface to a running image (see Coral, Gerry's comments, my comments). I suggest we go look at a few such things and see what we like or not. I'm told swank-js has a primitive/simple (hence understandable) architecture showing how to connect emacs + SLIME to node.js, so that's where I've started. With a similar back end in Pharo we should allow suitable separation to allow Coral to talk to it, AND allow emacs monkeys to talk to it, thus reducing the overall effort. To be precise: this lets Coral and emacs people do what they want on the client side while being able to share the server side. frank

Well for programming this is true, but even as programmer you type text quite often. This e.g is written using Emacs. It can handle anything which resembles text. Now do that with PharoEditor.

Even you handle text and you do not use Pharo for that. So yes it's a wonderful world of POT. It does not make sense to really pinpoint on the most weakest spots in ones Universe. No you are right everything is fine and that what is not fine, can be easily self-programmed. So make me an offer to implement a decent Editor in Pharo with at least a somewhat useful Gui. Should be a piece of cake shouldn't it? I will not stress you too much just something like Evolution yepp even outlook firebird would suite my needs. Now Smalltalk is now how old?

[Pharo-project] Swazoo + openID

by Bernat Romagosa

Hi list, We need to log a user into an application (not a Seaside app) using their google account, and we are using Swazoo as a server. It must be their google account because we need to retrieve and modify stuff stored in their google world (Blogger, Calendar, etc). We've taken a look at CloudFork, but it seems to be tied to Seaside and looks very complicated to use... are there any simpler alternatives? I guess the ideal solution would be to have a Swazoo extension that handled the authentication, is that right? Thanks! -- Bernat Romagosa.

Not any that won't merely magically start working the way you expect them to, like say (looking at the senders): SmallInteger maxVal +1 numberOfDigitsInBase: 0 Cheers, Henry
