Re: [Pharo-users] Could Pharo be more idiot-proof?
Daniel Thanks for the comments. I have tried Prolog too, but didn't get very far. I am hoping to deal with pretty arbitrary inputs (typically news stories from internet newspapers etc), but initially just searching for key words and phrases. So far I have used PP to construct a pretty good tokeniser to identify words, sentences, punctuation etc, which was not very difficult. It may be that I won't get very far, but I'm retired and I do this for fun, so what the heck.

Ben Brilliant! Many thanks, it's all there! I just need to find my way around Pharo - there is so much there.

Open a new workspace. In the title bar there is a small black triangle (Window menu).

I have just done something stupid, so this is just letting off steam (and maybe looking for someone else to blame!). Don’t worry. :) I have been playing with Moose (version 4.8), mainly because I want to experiment with PetitParser. I am struggling a bit, but getting somewhere I think. I have been trying out a lot of snippets in a workspace, before getting down to producing proper code. In a fit of madness, thinking I was closing a debugger window, I closed the workspace window.

My main Smalltalk experience is with Dolphin Smalltalk, and there, if you try to close a workspace, it asks if you want to save the contents first. Could Pharo have something similar? Normally it should. Now what I suggest is - use a class side methods like that you can version your scripts for free. - or am I the only idiot to do this? As a supplementary point, I am trying to use PetitParser to parse natural language. From the examples it is clear that PP is designed with formal languages in mind.
