pilog question about combined indexes

Hi, I tried the following : (? (select (@Tel) ( (mob +CuSu "37 176 86303") ) )) @Tel={C1} -> NIL : (? (select (@Tel) ( (mob +CuSu "37 176 86303" tel +CuSu "37 176 86303") ) )) -> NIL The first query returned as expected. The second one I believe means - look for "37 176 86303" either in

Re: pilog question about combined indexes

Thanks Alex ... I think I am getting there :) - It's pretty neat the more I get into it! If I understand correctly - the filter clause is redundant because it does not subset the records generated by the generator? When I look at the filter used in app/gui.l I wonder if the filter (range @Nr @@

Thanks Alex, I added index to +Update and the UI started giving me a drop down with the existing updates. That made me realize that what I really want is for the updates to show up uneditable ( NIL NIL '((NIL "Updates")) (do 8 ( NIL #(gui 1 '(+Obj

Wouldn't we need to link the update to the 'upds relation of Task? This does not quite work :( (menu "Tasks" (idForm ,"Tasks" '(choTsk) 'nr '+Tsk T '(may Delete) '((: nr)) (--) ( 2 "Name" (gui '(+E/R +Cue +TextField) '(nm : home obj) "Name" 40) "Desc" (gui

File offset

Hi all, Is there a way to get the file offset (which I can get using lseek)? I need this for my midi parsing project which contains variable length numbers (like UTF-8) and I think it will be useful to have something that can tell me the current file position. Ofcourse I can maintain it myself by

Hey Alex, What I need is an "and" - with collects, I do a (sect of L1 L2) ... I tried a bunch but cant seem to get "and" working - I need the items that are "RED" and "BLUE" :( Perhaps I have to adjust the ER to achieve this? regards, Kashyap On Tue, No

Hi Alex, Sorry to keep coming back to this :( Here's a new problem - as per the previous conversation, it seems that I could use "collect" to get the items that I am interested in. (let (RED (db 'nm '+TagVal "RED") BLUE (db 'nm '+TagVal "BLUE")) (setq L1 (collect 'v '+Tag RED RED

Re: Pilog query across multiple classes

Thanks Alex/Beneroth, Okay ... just to clarify. (collect 'nm '+Tag "BLUE" NIL T 'itm) is the recommended way to get to all items for a given Tag. I should perhaps use an indirection to +Tag class so that I do not repeat it every time. After some thinking it seems that perhaps I could just go with

Thanks Mattias, Yeah, intuitively, I do feel "symbols all the way down" makes Picolisp uniquely at an advantageous position. It would be good to be equipped with a way to articulate this advantage. Regards, Kashyap On Thu, Nov 28, 2019 at 11:28 AM Mattias Sundblad wrote: > Hi Kashyap! > > Thank
