Hello Alex,
Thank you much. 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

Hello Alex,
I got your mutt file, for my-guix-packages, but now I see I
need to learn Guile commands, I will do this somewhat later
when I have working system. Please help me until then, as
your style to make a modified package is excellent for me.
I guess you forgot the dependency gdbm, where to put it?
(define-module (my-guix-packages)
#:use-module (guix packages)
#:use-module (guix download)
#:use-module (guix utils)
#:use-module (gnu packages mail))
(define-public my-mutt
(package
(inherit mutt)
(name "my-mutt")
(arguments
(substitute-keyword-arguments (package-arguments mutt)
((#:configure-flags cf)
`(cons "--enable-hcache" ,cf))))
(synopsis (string-append (package-synopsis mutt)
" (configured with --enable-hcache)"))))

It is not my style :-) Package inheriting is a great feature of Guix,
it's just not documented (though "inherit" word can be met in the
manual several times).
> I guess you forgot the dependency gdbm, where to put it?
Sorry about that, but actually I didn't forget about it because I didn't
know it is needed (I've never used mutt, and I know nothing about it or
gdbm). Do you mean this dependency is needed because of --enable-hcache
option?
If so, then it can be added by adding gdbm to the inputs of my-mutt
package (see below). Also (my-guix-packages) module need to use (gnu
packages databases), because gdbm package comes from this module.
I hope the following comments clarify how my-mutt package is made:
> (define-module (my-guix-packages)
> #:use-module (guix packages)
> #:use-module (guix download)
> #:use-module (guix utils)
Don't forget to add this line here:
#:use-module (gnu packages databases)
> #:use-module (gnu packages mail))
>
> (define-public my-mutt
> (package
> (inherit mutt)
Inheriting means: those package fields that are not specified, will be
taken from mutt package. For example, the package name is changed (to
"my-mutt"), but the version is not, so it will be inherited. This means
when the version of mutt package will be updated, the version of my-mutt
package will automatically be updated too.
> (name "my-mutt")
> (arguments
> (substitute-keyword-arguments (package-arguments mutt)

> `(cons "--enable-hcache" ,cf))))
This means: take mutt's arguments and do some substitutions there. In
particular, we modify configure-flags by adding "--enable-hcache" to
them.
To add gdbm dependency, add the following line to the package
definition:
(inputs (cons `("gdbm" ,gdbm) (package-inputs mutt)))
> (synopsis (string-append (package-synopsis mutt)
> " (configured with --enable-hcache)"))))
Modifying synopsis is not needed, it is just what you see in the output
of "guix package --show=my-mutt" command.

Hello Alex,
Thank you much, it is working like this very good:
guix package -i my-mutt
by using this file: my-guix-packages.scm in ~/gnu/guix/packages:
(define-module (my-guix-packages)
#:use-module (guix packages)
#:use-module (guix download)
#:use-module (guix utils)
#:use-module (gnu packages mail)
#:use-module (gnu packages databases))
(define-public my-mutt
(package
(inherit mutt)
(name "my-mutt")
(inputs (cons `("gdbm" ,gdbm) (package-inputs mutt)))
(arguments
(substitute-keyword-arguments (package-arguments mutt)
((#:configure-flags cf)
`(cons "--enable-hcache" ,cf))))
(synopsis (string-append (package-synopsis mutt)
" (configured with --enable-hcache)"))))

Hello Alex,
I have followed your recommendation, and mutt is working modified.
However, now I get useless error messages. And I can imagine, if I have
modified 10 packages, that I would get 10x that much of error messages.

Let me stop with copy and paste, because there are many more lines like
that.
Maybe it is design of guix package manager, maybe it is my fault.
I understood that I can change definitions for guix packages, and such
would be installed. There shall be no warnings like this.
I do intend to make about 5-10 packages for system I use, and I worry
about future warning messages, it will be like 3-4 screens, making guix
package manager not user-friendly. I would not see real errors.

Now that you have my-mutt installed you can remove mutt

Hello Alex,
I have followed your recommendation, and mutt is working modified.
However, now I get useless error messages. And I can imagine, if I have
modified 10 packages, that I would get 10x that much of error messages.

Let me stop with copy and paste, because there are many more lines like
that.
Maybe it is design of guix package manager, maybe it is my fault.
I understood that I can change definitions for guix packages, and such
would be installed. There shall be no warnings like this.
I do intend to make about 5-10 packages for system I use, and I worry
about future warning messages, it will be like 3-4 screens, making guix
package manager not user-friendly. I would not see real errors.
