I'd like to run miniAdapton in Guile

here's the repo
https://github.com/fisherdj/miniAdapton

Now: how do I get it running in Guile ?

What are those .sld files ?

What about thos "define-library" and "library" forms ? Are those a r7rs
thing ?

For reference:

here's an amazing talk given by the awesome William Byrd

here's an article

Thanks in advance

Well, this requires a more time that I want to give to it to understand
it correctly.

FYI the following works:

~/src/guile/miniAdapton$ guile -L .
GNU Guile 2.2.0

Guile comes with ABSOLUTELY NO WARRANTY; for details type `,show w'.

Enter `,help' for help.
scheme@(guile-user)> (use-modules (miniadapton))
scheme@(guile-user)> (define-avar a 1)
scheme@(guile-user)> (avar-get a)
$1 = 1
scheme@(guile-user)> (define-avar b 2)
scheme@(guile-user)> (define-avar c (+ (avar-get a) (avar-get b)))
scheme@(guile-user)> (avar-get c)
$2 = 3
scheme@(guile-user)> (avar-set! a 10)
scheme@(guile-user)> (avar-get c)
$3 = 12

In theory this kind of framework could be put to good use, to implement
the equivalent of PostgreSQL Materialized view [1] that are refreshed
automatically.

How do you want to use it?

It seems to me that you already understood a lot !

Wonderful. So those "deine-library" and "library" forms are a vanilla
feature of Guile !

I want to keep a database AND a datastructure in ram in synch. I don't want
to read a view, for that.

I used to read the db when I was using your grf3, but now I'd lie to
minimize the traffic to/from the db.
