That looks like a solution that is valuable, and I would like to see that in future documentation. The info documentation and guix package --help now provide the option to read the file and evaluate from file, and I guess that this solution you provided is better for future: - people can learn Guile, scheme and programming - every user can modify the package.scm according to the needs I will copy this to guix-devel Louis On Fri, Mar 11, 2016 at 01:48:39PM +0300, Alex Kost wrote: > > > Hello Andreas, > > > > I have now 2 files in gnu/guix/packages/*.scm, for mutt and postgresql: > > and now I get each time on running guix, following: > > > > guix package: warning: failed to load '(databases)': > > ERROR: no code for module (databases) > > guix package: warning: failed to load '(mutt)': > > ERROR: no code for module (mutt) > > > > because 2 files are: databases.scm and mutt.scm > > > > I have already installed mutt, with changes, and it works.

I don't understand why Andreas recommended to use "guix > package -f". I think it is suitable to build some development > "guix.scm" file (not related, but see ¹).
