Hi Jone and welcome!

if you could share your attempts, it would help us understand what's
going on better. Then we can actually help you ;)

Please share your attempts! :)

The manual is not the best place to look for examples.  Instead, you'd
be best off looking at similar package declarations among the
distribution's official packages.  `guix` even provides a shortcut for
this, for instance:

  $ guix edit xfce4-battery-plugin



Off-topic:  I'm an mu4e user and for the past few e-mails Jone has sent,
they were all time-stamped from about 2 hours ahead in the future.
At UTC+1, I'm writing this at 17:27 while Jone's e-mail is timestamped
at 19:34.

Jone, would you have any clue why that is?  Anyone?

Here what happens is that you use libxfce4util, but it's not in any of 
the modules
you import. What you need to do is to find where this package comes 
from:

> guix package --show=libxfce4util

will tell you (among other things):

> location: gnu/packages/xfce.scm:81:2

so you need to use the module (guix packages xfce). Repeat this for any 
other missing
package variable. The module is the path reported by guix package, where 
you replace /
with spaces and ignore anything after the .scm extension.

Correction: I'm at UTC+2, like Julien.

Julien, you got the same time as me, right?

From the raw content of Jone's email,

--8<---------------cut here---------------start------------->8---
Date: Wed, 02 May 2018 18:43:27 +0000
--8<---------------cut here---------------end--------------->8---

The above date is still in the future as of this writing.  The timezone
must be wrong.

What's your system timezone?  I think there is some configuration clash
between Rmail, your SMTP agent and your system timezone.

> I go and look, but there are no comments :-(

Comments are only used when deemed necessary, that is, mostly for
unusual code.

For the first time it might take some time to grasp the mechanics of
Guix package declarations.  Proceed step by step, change by change,
until you get something working.  Post your code and the error message
and Guix users will be able to help you out.

That said, I reckon the manual would certainly benefit from a detailed
package declaration example where all fields would be carefully
dissected for the first-time packagers.

I don't use Rmail, so I'm a little clueless here.

Could you try sending an e-mail from Gmail's webmail?

What is this for?

Right way: define, build and install

[Jone]

On Gentoo I actively used github: download, then local build and install
in ~/{bin,tools}. It was easy! I didn't even need ebuilds and did not
think as this works :-)

Now I need several applications which are absent and will not be in
official repositories of a distribution. For an example:
1. https://github.com/x2b/usbeject
2. xfce4-cpugraph-plugin

I tried to define this as "some-package.scm" and build, but the first
requires some magic with gexp, and for the second - it is unknown what
for "use-modules". Finally, in the manual is just one stupid example
"hello"!

Help!!

Hello Jone,

It was hard to get started for me, too.  But after several package
recipes with a help of Guix community in the mailing list it's easy.

First of all in ‘(use-modules …)’ you could only specify Guile modules.

After we fix parentheses, then there will an error about no existing
‘(guix build)’ Guile module.  So let's remove it.

Here is a correct version, but it requires to add more modules to
‘(use-modules …)’ because of ‘native-inputs’ and ‘inputs’ in:
--8<---------------cut here---------------start------------->8---
(define-public xfce4-cpugraph-plugin
  (package
    (native-inputs …)
    (inputs …)))

Another way to find this sort of thing is to do a grep like the
following:

  grep -r 'define.*foo' ~/.config/guix/latest

I use that all the time to find service definitions, record type
definitions, syntax definitions, procedure definitions...all kinds of
definitions!

Привет, Олег. Мне наверно было бы проще писать на русском, не мучая
системы перевода и остальных участников рассылки. Дело в том, что я
нахожу время на систему только урывками. В стиле работает и черт с
этим. А все эти инсрументы, которые мне нужны.. короче, их
много. Поэтому я и обратился к теме сборки пакетов.

Без проблем.  ;-) Английский не является родным языком для многих.
Участники рассылки относятся с пониманием и всегда готовы помочь!

Я могу порекомендовать написать сообщение, как это сделал Pierre
Neidhardt.  [1] Возможно, что необходимый пакет уже есть у кого-то, но
неопубликован.  Если не будет ответа, мы всегда рады помочь со сборкой!

Обращаю внимание на то, что упомянутое сообщение стоит написать на
английском языке с целью привлечения большего количества человек.

                              Translation

The question was about packaging utilities.  I've advised to write an
email message similar to Pierre Neidhardt [1].  Also I told that we are
welcome to help with packaging.
