Hello Help! :-)

sorry but I'm new to Guile

please is there a way to include external .scm files in my main
config.scm, I tried with Guile local inclusion in config.scm

 (include base-services.scm)

but I get

.................
sudo guix system reconfigure config.scm
config.scm:8:0: error: extraneous field initializers (include)
................

thanks!
Giovanni

Hi,

You can create a module, say /etc/config/base-services.scm

To include it, you need to make it a module, so in base-services.scm:

(define-module (base-services)
  #:use-module (gnu services base)
  …
  #:export (my-services))
(define my-services (cons*.… %base-services))

And in your config.scm, you can import this module like so:

(add-to-load-path "/etc/config")
(use-modules (base-services))

(operating-system
  …
  (services my-services))

I don't think you can include a scheme file in the operating-system record directly, but maybe someone will prove me wrong :)

The ‘include’ form exists but you would need to use it at the top level.

However, I recommend using Guile’s module system instead.  An example of
that can be found here:

  • modules:
    https://git.savannah.gnu.org/cgit/guix/maintenance.git/tree/hydra/modules/sysadmin

  • config files that use these modules:
    https://git.savannah.gnu.org/cgit/guix/maintenance.git/tree/hydra/berlin.scm
    https://git.savannah.gnu.org/cgit/guix/maintenance.git/tree/hydra/build-machine.scm

Here, assuming you’re in the hydra/ directory, you’d simply run, say:

  guix system reconfigure -L ./modules ./berlin.scm

HTH!

OK, got it thanks!

ooooh: maintenance.git is *almost* more interesting than the guix manual
itself :-O

OK I'm still not able to hack my modules in Guile but that code is clear enough
for me to understand how it works... and it's great! (\me study!)

IaGC [1] is much more... *functional* than other forms of IaC :-)

got it!

kudos!
