Hi Guixers,

Are the modules that are automatically pulled in to a guix.scm or manifest.scm documented?

Those files are just scheme code but specifications->manifest is available in the global namespace, for example.

What else is there by default?

all best,

jgart

IIRC nothing is included by default.

I think it is at least (guix profiles).  When I try to work with the
`manifest.scm' file in the REPL, I need to explicitly (use-modules) it, but I do
not have to do it for `guix shell -m manifest.scm'.  Not sure if there are
others.

Have a nice day,
Tomas Volf

Note that guix repl manifest.scm will fail due to an unused import. This 
is special magic when passing a manifest with -m.

Their presence seems to be from how load-manifest in environment.scm 
works. https://www.gnu.org/software/guile/manual/html_node/Loading.html. 
See that it uses load*, not load, creating a temporary module with the 
(guix profiles) and (gnu) modules loaded.

We can confirm this with
(display (module-uses (current-module)))
(force-output)

at the top of the manifest. Everything in those two modules is in scope. 
Similarly, since (gnu) re-exports all (gnu ...) public modules (see 
gnu.scm), the (gnu packages) module is in scope, so we have 
specifications->manifest.

I definitely wouldn't rely on this behavior, but that's my understanding 
of it. Didn't notice any documentation.
