I'm only trying to understand how it would work with 2 Emacs, one in the main profile and one in another profile, which can be created from manifest. What I would like to achieve is, that I can do some literate programming in org-mode, while following along an online course about Erlang. In the past I had some pretty good experience with that approach to understanding some code and making sure I also write down what I understand, so that later on, I can go back and read again. I am not asking, whether this is a good or typical approach to any Erlang development. >> OK nice! I'll try it for a package!

I was thinking, that `ob-python` was missing, because I only found `emacs-ob-ipython`, but apparently `ob-python` does not exist and is instead built in? Because it works without me installing any `ob-python` Emacs package. Same seems to be true for `ob-scheme`. Only needed to install `geiser` I think. For now it seems nothing is missing. >> Also the edit thing `guix edit emacs-ob-erlang` sounds interesting. > It depends if you use Guix System or Guix as package manager solely. > For the latter, the 'edit' is read-only. > >> I just did the edit thing and I am not sure how to then "upload" a >> package.

I installed it on Trisquel 8 using the recommended install script. I did `guix pull` just like the error hinted, but still got the error. Now, a few terminals closed and opened later, it seems to work and give some output. ~~~~ (list (channel (name 'guix) (url "https://git.savannah.gnu.org/git/guix.git") (commit "6ebf300959a58fd1eda875205c75d21137862285"))) ~~~~ I think that is the normal intended output. >> I did another `guix pull` and `guix package -u` and this is after a >> fresh Guix package manager install and and installing the following >> packages: >> >> ~~~~ >> xiaolong@xlx200:~$ sudo -i guix package -I > Note that once you have configured your system (if you use Guix System), > you can run "guix pull" as a regular user and install package as regular > user, independently of what your system-wide is. Yep, sorry for that copy&paste error in my e-mail! The longer output was actually the output of the non-root profile already. >> The other command to show the count of packages also does not work for me: >> >> ~~~~ >> xiaolong@xlx200:/$ sudo du -sh gnu/packages/*.scm | sort -nr | head -n5 >> du: cannot access 'gnu/packages/*.scm': No such file or directory >> ~~~~ > You need to be in the Guix repo, i.e., you need to git clone > https://git.savannah.gnu.org/git/guix.git and the subfolder > gnu/packages/ contains all the packages stored by thematic. > > >> Do I need to create channels, like a custom way of structuring packages >> for myself, before running these commands? > To test and install your own packages, you have 3 choices: > > 1. ./pre-inst-env > 2. local channel > 3. --load-path > > The point #1 means you use the Contribution section, build Guix from > source, then add your package to the file gnu/packages/emacs-xyz.scm (of > the Git clone) and then run (from the Git cloned repo): > > ./pre-inst-env guix install emacs-foo > > The point #2 means you use a local Git repo containing your definitions > of packages.

I will need to read more about various terms in the Guix universe in its docs. I've not read that much yet and that is, why some terms and concepts are unclear to me.
