Hello hackers,
I am finally getting up to speed on the new service API, and I believe
I've run into a limitation of dmd services. I wanted to use 'match'
from (ice-9 match) in the "start" action for a dmd service, like so:
(dmd-service
(provision '(foo))
(documentation "Foo service.")
(requirement '(user-processes))
(start #~(begin
(use-modules (ice-9 match))
(match #$something
(foo ...))))
(stop #~(const #t)))
The problem is that, while the module is successfully imported, the
'match' form is not treated as syntax, and thus the service fails with
an unbound variable 'foo' exception. I hacked 'dmd-configuration-file'
in gnu/services/dmd.scm to import (ice-9 match) in the top-most
'use-modules' form of the 'config' gexp and then my service worked as
intended.
Am I just doing it wrong? If it's a real limitation, what would be the
best way to specify the additional modules needed? I looked around at
the various dmd services and couldn't find any other examples of needing
macros from another module. I would love to know how to resolve this so
that I can continue my quest of managing user SSH keys with a dmd
service.
Thanks,
