manually working with facts and queries e.g. > :do ^query()
  
 
Posted: May 13, 2019

I am trying to run some experiments using queries in order to workout some application logic. I am in ‘dual mode’, you know chatscript.exe. I am not in server mode or client mode.

Now, I have some facts that get created by tables. Here they are:

> :facts requiredby
216383: ( manywho-goalid requiredby repeating-manywho-goalid x100000 )
216382: ( manywho-code-goalid requiredby repeating-manywho-goalid x100000 )
216226: ( location-goalid requiredby provider-finder-goalid x100000 )
216223: ( support-bnumber-goalid requiredby support-unlock-account-goalid x100000 )
216220: ( manywho-code-goalid requiredby manywho-goalid x100000 ) 

using ^writefact and using ToSet parm for ^query kind of works. It only gives you the first fact in the set. How would I get the rest of them?

: > :do ^writefact( ^query( direct_v ? requiredby ? 2 ? @5fact) )
CHARLIE:  ( manywho-goalid requiredby repeating-manywho-goalid x100000 ) 

I do not seem to be able to manually run a query to get a fact collection and look at the results.


I thought I would use :fact @10 to show the fact set. Now facts do not stay between volleys so you can’t just do @10 = ^query() and then do :facts@10. But I thought ^save(@10) would do it. It does not.
This does not work.

: > :do ^save(@10 true)
CHARLIE:
: > :do @10 =  ^query( direct_v ? requiredby ? )
CHARLIE:
: > :facts @10
Fact set @10: 0 facts 

Using ^writeFact() does not work

> :do ^writefact( ^first( ^query(direct_v ? requiredby ?) ) )
CHARLIE: 


Is there any way to try these things without having to put it into a rule and recompile the bot?
I was hoping it would be a bit like :testPattern and :testtopic, where you can try things out on the system without having to rebuild.

For our bot we’ve written a ^dumpfactset() macro that will take a factset and write it to the screen. Then I can

> :do @1 = ^query(exact_s something ? ?) ^dumpfactset(@1)

The macro just loops through the fact set and does a ^writefact on each one.

Andy,

Thanks for the advice.

Care to share that little nugget of gold?

Don’t have the code with me here at home, but it is going to be something like:

^dumpfactset (^set)
{
    @0 = ^set
    ^loop() {
        $_f = ^first(@0fact)
        ^writefact($_f) \n
    }
}
