Hi simon!
I'll try to paraphrase my question:
If I run:
~~~~
guix time-machine \
--channels="${DIR}/channels.scm" -- \
environment \
--manifest="${DIR}/manifest.scm"
~~~~
Using the files I wrote about, how would I go about knowing, which
version of guile-json I am really using? What command can I run, that
will list me the versions of packages, which I installed into the
environment, which I am temporarily creating using the above command?
With version, I mean something like "3.5.0".
When I do:
~~~~
guix install guile-json
The following package will be installed:
guile-json 4.4.1
...
~~~~
I see the version. How can I look up that info in the created environment?
Regards,
Zelphir
