To do that, prefix each command with ‘./pre-inst-env’, as in:

* Packaging Guidelines
|
||||
|
||||
The GNU distribution is about respecting the freedom of users. Consequently,
|
||||
it contains only free software as defined at
|
||||
http://www.gnu.org/philosophy/free-sw.html .
|
||||
|
||||
In addition, we follow the [[http://www.gnu.org/distros/free-system-distribution-guidelines.html][free software distribution guidelines]]. Among other
|
||||
things, this means that the distribution tries hard not to steer users towards
|
||||
obtaining information about non-free software.

Such a recipe can be written by hand, and then tested by running

‘./pre-inst-env guix-build nettle’.
|

‘./pre-inst-env guix build nettle’.
|
||||
|

When writing the recipe, the base32-encoded SHA256 hash of the source
|
||||
code tarball, which can be seen in the example above, can be obtained by
|
||||
running:
|
||||
|

guix-download http://ftp.gnu.org/gnu/nettle/nettle-2.5.tar.gz
|
||||
guix download http://ftp.gnu.org/gnu/nettle/nettle-2.5.tar.gz
|

|

Alternatively, it is possible to semi-automatically import recipes from
|
||||
the [[http://nixos.org/nixpkgs/][Nixpkgs]] software distribution using this command:
|
||||
|
||||
guix-import /path/to/nixpkgs/checkout nettle
|
||||
guix import /path/to/nixpkgs/checkout nettle
|
||||
|

The command automatically fetches and converts to Guix the “Nix

expression” of Nettle.

* Submitting Patches
|
||||
|
||||
Development is done using the Git distributed version control system. Thus,
|
||||
access to the repository is not strictly necessary. We welcome contributions
|
||||
in the form of patches as produced by ‘git format-patch’ sent to
|
||||
bug-guix@gnu.org. Please write commit logs in the [[http://www.gnu.org/prep/standards/html_node/Change-Logs.html#Change-Logs][GNU ChangeLog format]].
|
||||
|
||||
As you become a regular contributor, you may find it convenient to have write
|
||||
access to the repository (see below.)
|

|
||||
* Commit Access
|
||||
|
||||
For frequent contributors, having write access to the repository is
|
||||
convenient. When you deem it necessary, feel free to ask for it on the
|
||||
mailing list. When you get commit access, please make sure to follow the
|
||||
policy below (discussions of the policy can take place on bug-guix@gnu.org.)
|
||||
|
||||
Non-trivial patches should always be posted to bug-guix@gnu.org (trivial
|
||||
patches include fixing typos, etc.)
|
||||
|
||||
For patches that just add a new package, and a simple one, it’s OK to commit,
|
||||
if you’re confident (which means you successfully built it in a chroot setup.)
|
||||
Likewise for package upgrades. We have a mailing list for commit
|
||||
notifications (guix-commits@gnu.org), so people can notice. Before pushing
|
||||
your changes, make sure to run ‘git pull --rebase’.
|
||||
|
||||
For anything else, please post to bug-guix@gnu.org and leave time for a
|
||||
review, without committing anything. If you didn’t receive any reply
|
||||
after two weeks, and if you’re confident, it’s OK to commit.
|
||||
|
||||
That last part is subject to being adjusted, allowing individuals to commit
|
||||
directly on non-controversial changes on parts they’re familiar with.
