05:15 <pablo_escoberg> Is there any way to list the relations for a particular class?

05:33 <abu[7]> You can do (show '+Item) or (v +Item)

05:39 <pablo_escoberg> (show '+Item) is close to what I need.  But it shows (I guess) the pointers to the relations rather than their definitions, and it prints them rather than returning them.  I need this programmatically (e.g. create a form with a field for every relation in a class).

05:41 <abu[7]> 'show' is just a debug frontend

05:41 <abu[7]> The relations are properties of the entity

05:42 <abu[7]> ap: (get '+Item 'nm 0)

05:42 <abu[7]> -> (+IdxFold +String)

05:42 <abu[7]> etc.

05:42 <pablo_escoberg> ok, so `getl` gets me a little closer.

05:44 <abu[7]> yes

05:45 <abu[7]> Or 'maps' as in 'show'

05:46 <abu[7]> (pp 'show) or (vi 'show)

05:46 <pablo_escoberg> those are fine for debugging.  I need to iterate over these things, but I think I'm on the right track.

05:47 <abu[7]> Nothing to do with debugging. I said 'maps'

05:47 <abu[7]> or as you said, 'getl'

05:47 <pablo_escoberg> right.  `maps` is probably what I need.

05:50 <abu[7]> I use both. 'maps' is more efficient, as it avoids 'cons'ing, but should not be used if the list may be modified in between

05:52 <pablo_escoberg> yeah, that's a reasonable assumption in this case.  Now I just need to figure out how to follow those pointers.

05:54 <abu[7]> Like above (get '+Item 'nm 0) ?

05:54 <pablo_escoberg> ah, yes, that should do it.  TY.

05:55 <abu[7]> @lib/db.l contains plenty of examples how relations are handled

05:56 <abu[7]> Given an object, it does things like (let Rel (meta This Var) ...

05:57 <abu[7]> 'Rel' is the relation object then

05:58 <pablo_escoberg> Great, I'll have a look.
