Error while loading first scm file

[Alex]

Hi!

I am trying to create my first Atomspace and therefore I have created scm file with the content (I want to express that there exists two classes - Invoice and Good):

(define InvoiceClass (ConceptNode "Invoice"))
(define GoodClass (ConceptNode "Good"))
!(cog-new-node ConceptNode "test1")

I have loaded succesfully this script in guile:

(use-modules (ice-9 readline)) (activate-readline)
(add-to-load-path "/usr/local/share/opencog/scm")
(add-to-load-path ".")
(use-modules (opencog))
(use-modules (opencog query))
(use-modules (opencog exec))
(use-modules (opencog atom-types))
(use-modules (opencog rule-engine))
(use-modules (opencog cogserver))
(add-to-load-path "/home/osboxes/Desktop/CiteauxSuite")

But I am receiving error message when I am trying to load CitauxLegal.scm file:

guile> (use-modules (CiteauxLegal))

What I am doing wrong? Why I can not load scm file but I can execute individual commands from my file (with (define...)). Is there available some simple scm file which I can load into my cogserver and run?

use-modules is like import in python, what you need is the equivalent of execfile in python, which in guile is load or primitive-load. primitive-load is preferred for big files, for speed.

You can get all guile reference in the following single web-page https://www.gnu.org/software/guile/manual/guile.html . To find details on primitive-load for example, find in page for "primitive-load:". The ":" will restrict the search to the index section, helping you land on the valid  link faster.

Cheers :-)

use-modules is used for loading OpenCog scm files/modules and it would be nice that I can create modules to. I can succesfully load scm file with the only instruction:

(define-module (CiteauxLegal))

But if I update this file and execute use-module repeatedly, then nothing happens. Is there command for unloading module or for reloading module in such way that it is recompiled? Such command is very desirable because it is quite expensive to start new guile session again after each modification of the single scm file.

use `,reload (CiteauxLegal)`
