Hi all - ASDF question: How do I tell ASDF that a system is already loaded? (I have CLX on AllegroCL loaded using (require :clx) but now ASDF does not know that CLX is already there...) - TIA !

frgo: it's possible that the clx that comes with allegro is not the "portable" clx that asdf would load.

Xach: Yeah - I am just running into issues now. Hm - I need to make McCLIM run on AllegroCL.

Well, I have a whole range of apps running using AllegroCL (using Franz' Allegrgraph DB). Now I want to have a fancy UI as a "control panel".

Allegro CL comes with its own CLIM and GUI system, I think they are likely more complete and usable than McCLIM. (I have not used any of them so I don't know for sure.)

I think if you asked Franz support they would steer you to their other thing, I have the impression they are trying to move customers off CLIM.

Xach: It is not clear that McCLIM is much less complete than Allegro these days. McCLIM has had a lot of work done lately. And certainly, McCLIM is better in many respects in that it is faster, and it uses the Xrender extension for fonts and anti-aliased drawing.

beach: do you have reference material for the inspiration behind https://github.com/robert-strandh/SICL/blob/master/Code/Loop/combinatory-parsing.lisp ?

I have used that technique a lot for ad hoc query compilation but have not read the foundational materials.

Cool, I was using monads and didn't know it! I got so much smarter just by knowing the right name!

https://lispblog.xach.com/post/147048601608/querying-plists is a variation - sometimes I use functions directly rather than involving a compilation step

beach: Hi. I undestand this documentation but not sure what protocol is. http://metamodular.com/CLOS-MOP/

I need to figure out a way to explain this to you, because if you don't know it, you are going to produce very bad code indeed. But dinner is imminent, so I don't have time to do it today.

Usually, if you define a "stack" module, you get an error if you pop from an empty stack.

Or else, POP does not return a value and there is a separate operation for returning the top element of the stack.

"these techniques work by (i) defining a set of object types and operations on them, which can support not just a single behavior, but a space or region of behaviors-this is commonly called a protocol;"
