Erlang Development with Guix
Hi Guixers, Has anyone tried loading any guix installed erlang libraries yet? I was thinking in an erlang shell (repl). Is there a guide that shows the particularities of using erlang with guix for development, or a mailing list thread I can read? Any help with that is much appreciated. all best, jgart
Help to debug a try with home-mcron-service-type on guix home
Hi guix !
I'm trying to config a mcron service type for mbsync, something
simple, but there are few example on the web for the new
home-mcron-service-type. I try something like this :
(use-modules (gnu packages mail)
(gnu packages tls)
(gnu home services mcron))
(define update-mail-service
#~(job '(next-minute '(range 0 60 5))
(lambda ()
(execl (string-append #$isync "/bin/mbsync")
"mbync"
"-a"))
"fetch mail"))
(define-public %mail-module
(home-module
(list mu
isync
imapfilter
msmtp
gnutls)
(list
(simple-service 'isync-mail-config-service
home-files-service-type
`(
(".mbsyncrc" ,(local-file
"../config/mail/mbsyncrc"))
(".msmtprc",(local-file
"../config/mail/msmtprc"))
(".imapfilter/config.lua",(local-file
"../config/mail/config.lua"
(simple-service `mcron-mail-update-service
home-mcron-service-type
(list update-mail-service))
)))
but when i run reconfigure, i have an error in drv compilation :

How to reinstall the bootloader without guix system reconfigure?
Hello everyone, Today, I shrank my Losedows (Windows) partition by 100 GB. Then I tried to boot Guix, but found that GRUB is broken and the GRUB rescue prompt appeared. I thought that it's because of the 100 GB empty space in my hard disk. Fortunately, I have Ubuntu (yet another nonfree distribution) installed and it didn't broke, so used that to add that 100 GB to my Guix partition. But I found that GRUB is still broken. Then I appended "/boot/grub/grub.cfg" of Guix to the same file of Ubuntu and managed to boot into Guix and to write this mail you're reading now. Now, if I'm correct, to fix the problem, I think the bootloader needs to be reinstalled. To do that, I have to run "guix system reconfigure". But that will download too many thing, much more than it actually needs. I know that "guix system delete-generations" also reinstalls bootloader while not downloading too many things, however I don't have any previous system generation, so I can't use that trick to reinstall the GRUB. Is there any way to reinstall bootloader without the costly "guix system reconfigure"? Another non-important question: Why did Guix's GRUB broke while Ubuntu's GRUB survived?
