Re: setting up my own channel (for some personal packages)

[Andreas Reuleaux <rx@a-rx.info>]

Hi,

thanks a lot, and yes: that was it.

I had not really understood that w/

  (define-module (gnu packages emacs-hide-comnt)

my emacs-hide-comnt package was searched in gnu/packages,
but oh well: this makes sense after all, and I am learning.

I have received your reply only privatly so far (to my rx@a-rx.info
address), not from the mailing list - but I am Cc'ing there
nevertheless already.

Fixed in my http://git.a-rx.info/channel now (i.e. emacs-hide-comnt.scm
updated there).

I will add more packages there, as I progress.

In case anyone wants to try my configuration: I am kind of lazy:
creating new initial commits all to often (instead of pushing them).

thus the ~/.config/guix/channels.scm needs to be changed accordingly,
currently:



--8<---------------cut here---------------start------------->8---
(cons (channel
       (name 'my-stuff)
                       
                       
       (url "git://git.a-rx.info/channel")

       (introduction
        (make-channel-introduction
         "109737fce5bd8f8f709646d3e1b2f519a07e2f9d"
         (openpgp-fingerprint
          "99BB E77D 73AE 07B9 D4B0  CA2E 3384 11E5 6E09 31B5")
         ))

       )
      %default-channels)
--8<---------------cut here---------------end--------------->8---


Many thanks again,

  -A
