如果你想折腾Guix本身，建议使用Git仓库里最新的版本：
|
|
||||||
|
|
||||||
@example
|
|
||||||
git clone https://git.savannah.gnu.org/git/guix.git
|
|
||||||
@end example
|
|
||||||
|
|
||||||
当从Git检出构建Guix时，除安装指导（@pxref{Requirements}）里提及的软件包之外还需
|
|
||||||
要这些包。
|
|
||||||
|
|
||||||
@itemize
|
|
||||||
@item @url{http://gnu.org/software/autoconf/, GNU Autoconf};
|
|
||||||
@item @url{http://gnu.org/software/automake/, GNU Automake};
|
|
||||||
@item @url{http://gnu.org/software/gettext/, GNU Gettext};
|
|
||||||
@item @url{http://gnu.org/software/texinfo/, GNU Texinfo};
|
|
||||||
@item @url{http://www.graphviz.org/, Graphviz};
|
|
||||||
@item @url{http://www.gnu.org/software/help2man/, GNU Help2man （可选）}。
|
|
||||||
@end itemize
|
|
||||||
|
|
||||||
设置Guix开发环境的最简单的方式当然是使用Guix！下面这些命令启动一个shell，所有的
|
|
||||||
依赖和环境变量都为折腾Guix设置好了：
|
|
||||||
|
|
||||||
@example
|
|
||||||
guix environment guix
|
|
||||||
@end example
|
|
||||||
|
|
||||||
这个命令更多的信息请参考@xref{Invoking guix environment}。额外的依赖可以通过
|
|
||||||
@option{--ad-hoc}选项添加：
|
|
||||||
|
|
||||||
@example
|
|
||||||
guix environment guix --ad-hoc help2man git strace
|
|
||||||
@end example
|
|
||||||
|
|
||||||
运行 @command{./bootstrap} 以使用Autoconf和Automake生成编译系统的基础框架。如果
|
|
||||||
你的得到这样的错误：
|
|
||||||
|
|
||||||
@example
|
|
||||||
configure.ac:46: error: possibly undefined macro: PKG_CHECK_MODULES
|
|
||||||
@end example
|
|
||||||
|
|
||||||
@noindent
|
|
||||||
它可能意味着Autoconf无法找到由pkg-config提供的@file{pkg.m4}。请确保@file{pkg.m4}
|
|
||||||
可用。由Guile提供的@file{guile.m4}宏也类似。假如你的Automake安装在
|
|
||||||
@file{/usr/local}，那么它不会从@file{/usr/share}里寻找@file{.m4}文件。这种情况下，
|
|
||||||
你必须执行下面这个命令：
|
|
||||||
|
|
||||||
@example
|
|
||||||
export ACLOCAL_PATH=/usr/share/aclocal
|
|
||||||
@end example
|
|
||||||
|
|
||||||
参考@xref{Macro Search Path,,, automake, The GNU Automake Manual}.
|
|
||||||
|
|
||||||
然后，像正常一样运行@command{./configure}。确保提供
|
|
||||||
@code{--localstatedir=@var{directory}}参数，@var{directory}是你当前系统的
|
|
||||||
@code{localstatedir}的值。（@pxref{The Store}）
|
|
||||||
|
|
||||||
最后，用@code{make check}执行测试（@pxref{Running the Test Suite}）。如果遇到任
|
|
||||||
何错误，请参考“安装指导”（@pxref{Installation}）或者给
|
|
||||||
@email{guix-devel@@gnu.org, 邮件列表}发邮件。

|
|

这样，即使你没有运行@code{make install}，所有的命令行工具都可以使用。为此，你先

|
|
||||||
@url{http://www.gnu.org/software/emacs, Emacs}，以及美妙的
|
|
||||||
@url{http://nongnu.org/geiser/, Geiser}。为此，请运行：
|
|
||||||
|
|
||||||
@example
|
|
||||||
guix package -i emacs guile emacs-geiser
|
|
||||||
@end example
|
|
||||||
|
|
||||||
Geiser允许在Emacs里进行交互式的、增长式的开发：buffer里的代码补全和执行，获取一
|
|
||||||
行的文档（docstrings），上下文敏感的补全，@kbd{M-.}跳转到对象定义，测试代码的
|
|
||||||
REPL，及更多（@pxref{Introduction,,, geiser, Geiser User Manual}）。为了方便的
|
|
||||||
Guix开发，请确保修改Guile的加载路径（load path）以使其能从你的项目里找到源代码文
|
|
||||||
件。

真正编辑代码时别忘了Emacs自带了方便的Scheme模式。而且，一定不要错过

@cindex 软件包, 创建
|
|
||||||
这个GNU发行版正在开发的早期阶段，可能缺少一些你喜欢的软件。这个章节介绍你可以怎
|
|
||||||
样帮助这个发行版成长。
|
|
||||||
|
|
||||||
自由软件通常以@dfn{源代码包}的形式分发，通常是包含完整代码的@file{tar.gz}包。添
|
|
||||||
加软件包到这个发行版意味着两件事：添加描述如何编译包的@dfn{配方}和一系列依赖软件，
|
|
||||||
以及添加配方之外的@dfn{软件包元数据}，如一段文字描述和证书信息。
|
|
||||||
|
|
||||||
在Guix里所有这些信息都包含在@dfn{软件包定义}里。软件包定义提供了软件包的高层视角。
|
|
||||||
它们使用Scheme编程语言编写，事实上，对每个软件包我们都定义一个绑定到软件包定义的
|
|
||||||
的变量，并且从模块（@pxref{Package Modules}）中导出那个变量。然而，深入的Scheme
|
|
||||||
知识@emph{不}是创建软件包的前提条件。若要了解软件包的更多信息，@pxref{Defining
|
|
||||||
Packages}。
|
|
||||||
|
|
||||||
一旦软件包定义准备好了，并且包存在Guix代码树的一个文件里，你可以用@command{guix
|
|
||||||
build} (@pxref{Invoking guix build})命令测试它。假设这个新软件包的名字叫做
|
|
||||||
@code{gnew}，你可以在Guix编译树里运行这个命令(@pxref{在安装之前运行Guix})：
|
|
||||||
|
|
||||||
@example
|
|
||||||
./pre-inst-env guix build gnew --keep-failed
|
|
||||||
@end example
|
|
||||||
|
|
||||||
使用@code{--keep-failed}参数会保留失败的编译树，这可以使调试编译错误更容易。
|
|
||||||
@code{--log-file}也是一个调试时很有用的参数，它可以用来访问编译日志。
|
|
||||||
|
|
||||||
如果@command{guix}命令找不到这个软件包，那可能是因为源文件包含语法错误，或者缺少
|
|
||||||
导出软件包的@code{define-public}语句。为了查找错误，你可以用Guile导入这个模块以
|
|
||||||
了解这个错误的详情：
|
|
||||||
|
|
||||||
@example
|
|
||||||
./pre-inst-env guile -c '(use-modules (gnu packages gnew))'
|
|
||||||
@end example
|
|
||||||
|
|
||||||
一旦你的软件包可以正确编译，请给我们发送补丁（@pxref{提交补丁}）。当然，
|
|
||||||
如果你需要帮助，我们也会很乐意帮助你。一旦补丁被提交到Guix仓库里，这个新的软件包
|
|
||||||
会被自动地在支持的平台上编译@url{http://hydra.gnu.org/jobset/gnu/master, our
|
|
||||||
continuous integration system}。
|
|
||||||
|
|
||||||
@cindex substituter
|
|
||||||
用户可以通过运行@command{guix pull}命令获取最新的软件包定义（@pxref{Invoking
|
|
||||||
guix pull}）。当@code{@value{SUBSTITUTE-SERVER}}编译好这些软件包之后，安装这些软
|
|
||||||
件包时会自动从服务器（@pxref{Substitutes}）上下载编译好的二进制包。唯一需要人工
|
|
||||||
干预的地方是评审和应用代码补丁。

|
|
||||||
以源代码形式学习和修改程序的自由，原样重新分发副本的自由，和分发修改后的版本的自
|
|
||||||
由。GNU发行版里包含的软件包只提供遵守这四项自由的软件。
|
|
||||||
|
|

此外，GNU发行版遵循
|

@url{http://www.gnu.org/distros/free-system-distribution-guidelines.html,自由软

|
|
||||||
|
|
||||||
某些上游的软件包源代码包含一小部分违反上述准则的可选的子集，比如这个子集本身就是
|
|
||||||
非自由代码。这时，这些讨厌的代码需要用合适的补丁或者软件包定义（@pxref{Defining

@cindex 软件包名字
|
|

一个软件包事实上有两个名字：第一个是@emph{Scheme变量}的名字，即用
|
|
||||||
@code{define-public}定义的名字。通过这个名字，软件包可以被Scheme代码找到，如用作
|
|
||||||
其它软件包的输入。第二个名字是软件包定义里的@code{name}属性的字符串值。这个名字
|
|
||||||
用于软件包管理命令，如：@command{guix package}，@command{guix build}
|
|
||||||
|
|
||||||
两个名字通常是相同的，常是上游项目名字转成小写字母并把下划线替换成连字符的结果。
|
|
||||||
比如，GNUnet转成@code{gnunet}，SDL_net转成@code{sdl-net}。
|
|
||||||
|
|
||||||
我们不给库软件包添加@code{lib}前缀，除非它是项目官方名字的一部分。但是
|
|
||||||
@pxref{Python模块}和@ref{Perl模块}有关于Python和Perl语言的特殊规则。
|
|

@cindex 软件包版本
|
|
||||||
我们通常只为每个自由软件的最新版本打包。但是有时候，比如对于版本不兼容的库，需要
|
|
||||||
有同一个软件包的两个或更多版本。它们需要使用不同的Scheme变量名。我们为最新的版本
|
|
||||||
使用@ref{软件包命名}里规定的名字，旧的版本使用加上后缀的名字，后缀是@code{-}
|
|
||||||
和可以区分开版本号的版本号的最小前缀。
|
|
||||||
|
|
||||||
软件包定义里的名字对于同一个软件包的所有版本都是相同的，并且不含有版本号。
|
|
||||||
|
|
||||||
例如，GTK+的2.24.20和3.9.12两个版本可以这样打包：
|
|
||||||
|
|
||||||
@example
|
|
||||||
(define-public gtk+
|
|
||||||
(package
|
|
||||||
(name "gtk+")
|
|
||||||
(version "3.9.12")
|
|
||||||
...))
|
|
||||||
(define-public gtk+-2
|
|
||||||
(package
|
|
||||||
(name "gtk+")
|
|
||||||
(version "2.24.20")
|
|
||||||
...))
|
|
||||||
@end example
|
|
||||||
如果我们还需要GTK+ 3.8.2，就这样打包
|
|
||||||
@example
|
|
||||||
(define-public gtk+-3.8
|
|
||||||
(package
|
|
||||||
(name "gtk+")
|
|
||||||
(version "3.8.2")
|
|
||||||
...))
|
|
||||||

|
|
||||||
@cindex 用于版本控制快照的版本号
|
|
||||||
有时候，我们为软件包上游的版本控制系统（VCS）的快照而不是正式发布版打包。这是特
|
|
||||||
殊情况，因为决定哪个是稳定版的权力应该属于上游开发者。然而，有时候这是必须的。那
|
|
||||||
么，我们该如何决定写在@code{version}里的版本号呢？
|
|
||||||
|
|
||||||
显然，我们需要让VCS快照的commit ID在版本号中体现出来，但是我们也需要确保版本号单
|
|
||||||
调递增，以便@command{guix package --upgrade}决定哪个版本号更新。由于commit ID，
|
|
||||||
尤其是Git的commit ID，不是单调递增的，我们添加一个每次升级快照时都手动增长的
|
|
||||||
revision数字。最后的版本号字符串看起来是这样：
|
|
||||||
|
|
||||||
@example
|
|
||||||
2.0.11-3.cabba9e
|
|
||||||
^ ^ ^
|
|
||||||
| | `-- 上游的commit ID
|
|
||||||
| |
|
|
||||||
| `--- Guix软件包的revision
|
|
||||||
|
|
|
||||||
最新的上游版本号
|
|
||||||
@end example
|
|
||||||
|
|
||||||
把@code{版本号}里的commit ID截短，比如只取7个数字，是一个好主意。它避免了美学上
|
|
||||||
的烦恼（假设美学在这里很重要），以及操作系统限制引起的问题（比如Linux内核的127字
|
|
||||||
节）。尽管如此，在@code{origin}里最好使用完整的commit ID，以避免混淆。
|
|
||||||
|
|
||||||
@example
|
|
||||||
(define my-package
|
|
||||||
(let ((commit "c3f29bc928d5900971f65965feaae59e1272a3f7")

@subsection 简介和描述
|
|
||||||
|
|
||||||
@cindex 软件包描述
|
|
||||||
@cindex 软件包简介
|
|
||||||
我们已经看到，GNU@tie{}Guix里的每个软件包都包含一个简介（synopsis）和一个描述
|
|
||||||
（description）（@pxref{Defining Packages}）。简介和描述很重要：它们是
|
|
||||||
@command{guix package --search}搜索的信息，并且是帮助用户决定一个软件包是否符合
|
|
||||||
自己需求的重要信息。因此，打包的人应该关注怎样写它们的内容。
|
|
||||||
|
|
||||||
简介必须以大写字母开头，并且不能以句号结尾。它们不能以 ``a'' 或者 ``the'' 等没有
|
|
||||||
意义的词开头。例如 ``File-frobbing tool'' 要比 ``A tool that frobs files'' 更好。
|
|
||||||
简介需要说明软件包是什么－－如 ``Core GNU utilities (file, text, shell)''，或者
|
|
||||||
它的用途－－如 GNU@tie{}grep 的简介是 ``Print lines matching a pattern''。
|
|
||||||
|
|
||||||
Keep in mind that the synopsis must be meaningful for a very wide audience.
|
|
||||||
For example, ``Manipulate alignments in the SAM format'' might make sense
|
|
||||||
for a seasoned bioinformatics researcher, but might be fairly unhelpful or
|
|
||||||
even misleading to a non-specialized audience. It is a good idea to come up
|
|
||||||
with a synopsis that gives an idea of the application domain of the
|
|
||||||
package. In this example, this might give something like ``Manipulate
|
|
||||||
nucleotide sequence alignments'', which hopefully gives the user a better
|
|
||||||
idea of whether this is what they are looking for.
|
|
||||||
|
|
||||||
Descriptions should take between five and ten lines. Use full sentences,
|
|
||||||
and avoid using acronyms without first introducing them. Please avoid
|
|
||||||
marketing phrases such as ``world-leading'', ``industrial-strength'', and
|
|
||||||
``next-generation'', and avoid superlatives like ``the most
|
|
||||||
advanced''---they are not helpful to users looking for a package and may
|
|
||||||
even sound suspicious. Instead, try to be factual, mentioning use cases and
|
|
||||||
features.
|
|
||||||
|
|
||||||
@cindex Texinfo markup, in package descriptions
|
|
||||||
Descriptions can include Texinfo markup, which is useful to introduce
|
|
||||||
ornaments such as @code{@@code} or @code{@@dfn}, bullet lists, or hyperlinks
|
|
||||||
(@pxref{Overview,,, texinfo, GNU Texinfo}). However you should be careful
|
|
||||||
when using some characters for example @samp{@@} and curly braces which are
|
|
||||||
the basic special characters in Texinfo (@pxref{Special Characters,,,
|
|
||||||
texinfo, GNU Texinfo}). User interfaces such as @command{guix package
|
|
||||||
--show} take care of rendering it appropriately.
|
|
||||||
|
|
||||||
Synopses and descriptions are translated by volunteers
|
|
||||||
@uref{http://translationproject.org/domain/guix-packages.html, at the
|
|
||||||
Translation Project} so that as many users as possible can read them in
|
|
||||||
their native language. User interfaces search them and display them in the
|
|
||||||
language specified by the current locale.
|
|
||||||
|
|
||||||
To allow @command{xgettext} to extract them as translatable strings,
|
|
||||||
synopses and descriptions @emph{must be literal strings}. This means that
|
|
||||||
you cannot use @code{string-append} or @code{format} to construct these
|
|
||||||
strings:
|
|
||||||
|
|
||||||
@lisp
|
|
||||||
(package
|
|
||||||
;; @dots{}
|
|
||||||
(synopsis "This is translatable")
|
|
||||||
(description (string-append "This is " "*not*" " translatable.")))
|
|
||||||
@end lisp
|
|
||||||
|
|
||||||
Translation is a lot of work so, as a packager, please pay even more
|
|
||||||
attention to your synopses and descriptions as every change may entail
|
|
||||||
additional work for translators. In order to help them, it is possible to
|
|
||||||
make recommendations or instructions visible to them by inserting special
|
|
||||||
comments like this (@pxref{xgettext Invocation,,, gettext, GNU Gettext}):
|
|
||||||
|
|
||||||
@example
|
|
||||||
;; TRANSLATORS: "X11 resize-and-rotate" should not be translated.
|
|
||||||

|
|
||||||

@node Python模块
|
|
||||||
@subsection Python模块
|
|
||||||
|
|
||||||
@cindex python
|
|
||||||
We currently package Python 2 and Python 3, under the Scheme variable names
|
|
||||||
@code{python-2} and @code{python} as explained in @ref{版本号}. To
|
|
||||||
avoid confusion and naming clashes with other programming languages, it
|
|
||||||
seems desirable that the name of a package for a Python module contains the
|
|
||||||
word @code{python}.
|
|
||||||
|
|
||||||
Some modules are compatible with only one version of Python, others with
|
|
||||||
both. If the package Foo compiles only with Python 3, we name it
|
|
||||||
@code{python-foo}; if it compiles only with Python 2, we name it
|
|
||||||
@code{python2-foo}. If it is compatible with both versions, we create two
|
|
||||||
packages with the corresponding names.
|
|
||||||
|
|
||||||
If a project already contains the word @code{python}, we drop this; for
|
|
||||||
instance, the module python-dateutil is packaged under the names
|
|
||||||
@code{python-dateutil} and @code{python2-dateutil}. If the project name
|
|
||||||
starts with @code{py} (e.g.@: @code{pytz}), we keep it and prefix it as
|
|
||||||
described above.
|
|
||||||
|
|
||||||
@subsubsection Specifying Dependencies
|
|
||||||
@cindex inputs, for Python packages
|
|
||||||
|
|
||||||
Dependency information for Python packages is usually available in the
|
|
||||||
package source tree, with varying degrees of accuracy: in the
|
|
||||||
@file{setup.py} file, in @file{requirements.txt}, or in @file{tox.ini}.
|
|
||||||
|
|
||||||
Your mission, when writing a recipe for a Python package, is to map these
|
|
||||||
dependencies to the appropriate type of ``input'' (@pxref{package Reference,
|
|
||||||
inputs}). Although the @code{pypi} importer normally does a good job
|
|
||||||
(@pxref{Invoking guix import}), you may want to check the following check
|
|
||||||
list to determine which dependency goes where.
|
|
||||||
|
|
||||||
@itemize
|
|
||||||
|
|
||||||
@item
|
|
||||||
We currently package Python 2 with @code{setuptools} and @code{pip}
|
|
||||||
installed like Python 3.4 has per default. Thus you don't need to specify
|
|
||||||
either of these as an input. @command{guix lint} will warn you if you do.
|
|
||||||
|
|
||||||
@item
|
|
||||||
Python dependencies required at run time go into @code{propagated-inputs}.
|
|
||||||
They are typically defined with the @code{install_requires} keyword in
|
|
||||||
@file{setup.py}, or in the @file{requirements.txt} file.
|
|
||||||
|
|
||||||
@item
|
|
||||||
Python packages required only at build time---e.g., those listed with the
|
|
||||||
@code{setup_requires} keyword in @file{setup.py}---or only for
|
|
||||||
testing---e.g., those in @code{tests_require}---go into
|
|
||||||
@code{native-inputs}. The rationale is that (1) they do not need to be
|
|
||||||
propagated because they are not needed at run time, and (2) in a
|
|
||||||
cross-compilation context, it's the ``native'' input that we'd want.
|
|
||||||
|
|
||||||
Examples are the @code{pytest}, @code{mock}, and @code{nose} test
|
|
||||||
frameworks. Of course if any of these packages is also required at
|
|
||||||
run-time, it needs to go to @code{propagated-inputs}.
|
|
||||||
|
|
||||||
@item
|
|
||||||
Anything that does not fall in the previous categories goes to
|
|
||||||
@code{inputs}, for example programs or C libraries required for building
|
|
||||||
Python packages containing C extensions.
|
|
||||||
|
|
||||||
@item
|
|
||||||
If a Python package has optional dependencies (@code{extras_require}), it is
|
|
||||||
up to you to decide whether to add them or not, based on their
|
|
||||||
usefulness/overhead ratio (@pxref{提交补丁, @command{guix size}}).

@node Perl模块
|
|
||||||
@subsection Perl模块
|
|
||||||
|
|
||||||
@cindex perl
|
|
||||||
Perl programs standing for themselves are named as any other package, using
|
|
||||||
the lowercase upstream name. For Perl packages containing a single class,
|
|
||||||
we use the lowercase class name, replace all occurrences of @code{::} by
|
|
||||||
dashes and prepend the prefix @code{perl-}. So the class @code{XML::Parser}
|
|
||||||
becomes @code{perl-xml-parser}. Modules containing several classes keep
|
|
||||||
their lowercase upstream name and are also prepended by @code{perl-}. Such
|
|
||||||
modules tend to have the word @code{perl} somewhere in their name, which
|
|
||||||
gets dropped in favor of the prefix. For instance, @code{libwww-perl}
|
|
||||||
becomes @code{perl-libwww}.

@node Java包

@subsection Java包
|

|
|

@cindex java
|
|
||||||
Java programs standing for themselves are named as any other package, using
|
|
||||||
the lowercase upstream name.
|
|
||||||
|
|
||||||
To avoid confusion and naming clashes with other programming languages, it
|
|
||||||
is desirable that the name of a package for a Java package is prefixed with
|
|
||||||
@code{java-}. If a project already contains the word @code{java}, we drop
|
|
||||||
this; for instance, the package @code{ngsjava} is packaged under the name
|
|
||||||
@code{java-ngs}.
|
|
||||||
|
|
||||||
For Java packages containing a single class or a small class hierarchy, we
|
|
||||||
use the lowercase class name, replace all occurrences of @code{.} by dashes
|
|
||||||
and prepend the prefix @code{java-}. So the class @code{apache.commons.cli}
|
|
||||||
becomes package @code{java-apache-commons-cli}.

|
|
||||||
|
|
||||||
@node 字体
|
|
||||||
@subsection 字体
|
|
||||||
|
|
||||||
@cindex fonts
|
|
||||||
For fonts that are in general not installed by a user for typesetting
|
|
||||||
purposes, or that are distributed as part of a larger software package, we
|
|
||||||
rely on the general packaging rules for software; for instance, this applies
|
|
||||||
to the fonts delivered as part of the X.Org system or fonts that are part of
|
|
||||||
TeX Live.
|
|
||||||
|
|
||||||
To make it easier for a user to search for fonts, names for other packages
|
|
||||||
containing only fonts are constructed as follows, independently of the
|
|
||||||
upstream package name.
|
|
||||||
|
|
||||||
The name of a package containing only one font family starts with
|
|
||||||
@code{font-}; it is followed by the foundry name and a dash @code{-} if the
|
|
||||||
foundry is known, and the font family name, in which spaces are replaced by
|
|
||||||
dashes (and as usual, all upper case letters are transformed to lower
|
|
||||||
case). For example, the Gentium font family by SIL is packaged under the
|
|
||||||
name @code{font-sil-gentium}.
|
|
||||||
|
|
||||||
For a package containing several font families, the name of the collection
|
|
||||||
is used in the place of the font family name. For instance, the Liberation
|
|
||||||
fonts consist of three families, Liberation Sans, Liberation Serif and
|
|
||||||
Liberation Mono. These could be packaged separately under the names
|
|
||||||
@code{font-liberation-sans} and so on; but as they are distributed together
|
|
||||||
under a common name, we prefer to package them together as
|
|
||||||
@code{font-liberation}.
|
|
||||||
|
|
||||||
In the case where several formats of the same font family or font collection
|
|
||||||
are packaged separately, a short form of the format, prepended by a dash, is
|
|
||||||
added to the package name. We use @code{-ttf} for TrueType fonts,
|
|
||||||
@code{-otf} for OpenType fonts and @code{-type1} for PostScript Type 1
|
|
||||||
fonts.

@subsection Programming Paradigm
|
|
||||||
|
|
||||||
Scheme code in Guix is written in a purely functional style. One exception
|
|
||||||
is code that involves input/output, and procedures that implement low-level
|
|
||||||
concepts, such as the @code{memoize} procedure.
|
|
||||||
|
|
||||||
@node Modules
|
|
||||||
@subsection Modules
|
|
||||||
|
|
||||||
Guile modules that are meant to be used on the builder side must live in the
|
|
||||||
@code{(guix build @dots{})} name space. They must not refer to other Guix
|
|
||||||
or GNU modules. However, it is OK for a ``host-side'' module to use a
|
|
||||||
build-side module.
|
|
||||||
|
|
||||||
Modules that deal with the broader GNU system should be in the @code{(gnu
|
|
||||||
@dots{})} name space rather than @code{(guix @dots{})}.
|
|
||||||
|
|
||||||
@node Data Types and Pattern Matching
|
|
||||||
@subsection Data Types and Pattern Matching
|
|
||||||
|
|
||||||
The tendency in classical Lisp is to use lists to represent everything, and
|
|
||||||
then to browse them ``by hand'' using @code{car}, @code{cdr}, @code{cadr},
|
|
||||||
and co. There are several problems with that style, notably the fact that
|
|
||||||
it is hard to read, error-prone, and a hindrance to proper type error
|
|
||||||
reports.
|
|
||||||
|
|
||||||
Guix code should define appropriate data types (for instance, using
|
|
||||||
@code{define-record-type*}) rather than abuse lists. In addition, it should
|
|
||||||
use pattern matching, via Guile’s @code{(ice-9 match)} module, especially
|
|
||||||
when matching lists.
|
|
||||||
|
|
||||||
@node Formatting Code
|
|
||||||
@subsection Formatting Code
|
|
||||||
|
|
||||||
@cindex formatting code
|
|
||||||
@cindex coding style
|
|
||||||
When writing Scheme code, we follow common wisdom among Scheme programmers.
|
|
||||||
In general, we follow the @url{http://mumble.net/~campbell/scheme/style.txt,
|
|
||||||
Riastradh's Lisp Style Rules}. This document happens to describe the
|
|
||||||
conventions mostly used in Guile’s code too. It is very thoughtful and well
|
|
||||||
written, so please do read it.
|
|
||||||
|
|
||||||
Some special forms introduced in Guix, such as the @code{substitute*} macro,
|
|
||||||
have special indentation rules. These are defined in the
|
|
||||||
@file{.dir-locals.el} file, which Emacs automatically uses. Also note that
|
|
||||||
Emacs-Guix provides @code{guix-devel-mode} mode that indents and highlights
|
|
||||||
Guix code properly (@pxref{Development,,, emacs-guix, The Emacs-Guix
|
|
||||||
Reference Manual}).
|
|
||||||
|
|
||||||
@cindex indentation, of code
|
|
||||||
@cindex formatting, of code
|
|
||||||
If you do not use Emacs, please make sure to let your editor knows these
|
|
||||||
rules. To automatically indent a package definition, you can also run:
|
|
||||||
|
|
||||||
@example
|
|
||||||
./etc/indent-code.el gnu/packages/@var{file}.scm @var{package}
|
|
||||||
@end example
|
|
||||||
|
|
||||||
@noindent
|
|
||||||
This automatically indents the definition of @var{package} in
|
|
||||||
@file{gnu/packages/@var{file}.scm} by running Emacs in batch mode. To
|
|
||||||
indent a whole file, omit the second argument:
|
|
||||||
|
|
||||||
@example
|
|
||||||
./etc/indent-code.el gnu/services/@var{file}.scm
|
|
||||||
@end example
|
|
||||||
|
|
||||||
@cindex Vim, Scheme code editing
|
|
||||||
If you are editing code with Vim, we recommend that you run @code{:set
|
|
||||||
autoindent} so that your code is automatically indented as you type.

||||||

@code{paredit.vim}} may help you deal with all these parentheses.

We require all top-level procedures to carry a docstring. This requirement
|
|
||||||
can be relaxed for simple private procedures in the @code{(guix build
|
|
||||||
@dots{})} name space, though.
|
|
||||||
|
|
||||||
Procedures should not have more than four positional parameters. Use
|
|
||||||
keyword parameters for procedures that take more than four parameters.

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 @code{git format-patch}
|
|
||||||
sent to the @email{guix-patches@@gnu.org} mailing list.
|
|
||||||
|
|
||||||
This mailing list is backed by a Debbugs instance accessible at
|
|
||||||
@uref{https://bugs.gnu.org/guix-patches}, which allows us to keep track of
|
|
||||||
submissions. Each message sent to that mailing list gets a new tracking
|
|
||||||
number assigned; people can then follow up on the submission by sending
|
|
||||||
email to @code{@var{NNN}@@debbugs.gnu.org}, where @var{NNN} is the tracking
|
|
||||||
number (@pxref{Sending a Patch Series}).
|
|
||||||
|
|
||||||
Please write commit logs in the ChangeLog format (@pxref{Change Logs,,,
|
|
||||||

Before submitting a patch that adds or modifies a package definition, please
|
|
||||||
run through this check list:
|
|

||||||
@enumerate
|
|
||||||
@item
|
|
||||||
If the authors of the packaged software provide a cryptographic signature
|
|
||||||
for the release tarball, make an effort to verify the authenticity of the
|
|
||||||
archive. For a detached GPG signature file this would be done with the
|
|
||||||
@code{gpg --verify} command.
|
|
||||||
|
|
||||||
@item
|
|
||||||
Take some time to provide an adequate synopsis and description for the

|
|

@item
|
|
||||||
Run @code{guix lint @var{package}}, where @var{package} is the name of the
|
|
||||||
new or modified package, and fix any errors it reports (@pxref{Invoking guix
|
|
||||||
lint}).
|
|
||||||
|
|
||||||
@item
|
|
||||||
Make sure the package builds on your platform, using @code{guix build
|
|
||||||
@var{package}}.
|
|
||||||
|
|
||||||
@item
|
|
||||||
We recommend you also try building the package on other supported
|
|
||||||
platforms. As you may not have access to actual hardware platforms, we
|
|
||||||
recommend using the @code{qemu-binfmt-service-type} to emulate them. In
|
|
||||||
order to enable it, add the following service to the list of services in
|
|
||||||
your @code{operating-system} configuration:
|
|
||||||
|
|
||||||
@example
|
|
||||||
(service qemu-binfmt-service-type
|
|
||||||
(qemu-binfmt-configuration
|
|
||||||
(platforms (lookup-qemu-platforms "arm" "aarch64" "mips64el"))
|
|
||||||
(guix-support? #t)))
|
|
||||||
@end example
|
|
||||||
|
|
||||||
Then reconfigure your system.
|
|
||||||
|
|
||||||
You can then build packages for different platforms by specifying the
|
|
||||||
@code{--system} option. For example, to build the "hello" package for the
|
|
||||||
armhf, aarch64, or mips64 architectures, you would run the following
|
|
||||||
commands, respectively:
|
|
||||||
@example
|
|
||||||
guix build --system=armhf-linux --rounds=2 hello
|
|
||||||
guix build --system=aarch64-linux --rounds=2 hello
|
|
||||||
guix build --system=mips64el-linux --rounds=2 hello
|
|
||||||
@end example

||||||

@cindex bundling
|
|
||||||
Make sure the package does not use bundled copies of software already
|
|
||||||
available as separate packages.
|
|
||||||
|
|
||||||
Sometimes, packages include copies of the source code of their dependencies
|
|
||||||
as a convenience for users. However, as a distribution, we want to make
|
|
||||||
sure that such packages end up using the copy we already have in the
|
|
||||||
distribution, if there is one. This improves resource usage (the dependency
|
|
||||||
is built and stored only once), and allows the distribution to make
|
|
||||||
transverse changes such as applying security updates for a given software
|
|
||||||
package in a single place and have them affect the whole system---something
|
|
||||||
that bundled copies prevent.
|
|
||||||
|
|
||||||
@item
|
|
||||||
Take a look at the profile reported by @command{guix size} (@pxref{Invoking
|
|
||||||
guix size}). This will allow you to notice references to other packages
|
|
||||||
unwillingly retained. It may also help determine whether to split the
|
|
||||||
package (@pxref{Packages with Multiple Outputs}), and which optional
|
|
||||||
dependencies should be used. In particular, avoid adding @code{texlive} as
|
|
||||||
a dependency: because of its extreme size, use @code{texlive-tiny} or
|
|
||||||
@code{texlive-union} instead.
|
|
||||||
|
|
||||||
@item
|
|
||||||
For important changes, check that dependent package (if applicable) are not
|
|
||||||
affected by the change; @code{guix refresh --list-dependent @var{package}}
|
|
||||||
will help you do that (@pxref{Invoking guix refresh}).

@cindex branching strategy
|
|
||||||
@cindex rebuild scheduling strategy
|
|
||||||
Depending on the number of dependent packages and thus the amount of
|
|
||||||
rebuilding induced, commits go to different branches, along these lines:
|
|
||||||
|
|
||||||
@table @asis
|
|
||||||
@item 300 dependent packages or less
|
|
||||||
@code{master} branch (non-disruptive changes).
|
|
||||||
|
|
||||||
@item between 300 and 1,200 dependent packages
|
|
||||||
@code{staging} branch (non-disruptive changes). This branch is intended to
|
|
||||||
be merged in @code{master} every 3 weeks or so. Topical changes (e.g., an
|
|
||||||
update of the GNOME stack) can instead go to a specific branch (say,
|
|
||||||
@code{gnome-updates}).
|
|
||||||
|
|
||||||
@item more than 1,200 dependent packages
|
|
||||||
@code{core-updates} branch (may include major and potentially disruptive
|
|
||||||
changes). This branch is intended to be merged in @code{master} every 2.5
|
|
||||||
months or so.
|
|
||||||
@end table
|
|
||||||
|
|
||||||
All these branches are @uref{https://hydra.gnu.org/project/gnu, tracked by
|
|
||||||
our build farm} and merged into @code{master} once everything has been
|
|
||||||
successfully built. This allows us to fix issues before they hit users, and
|
|
||||||
to reduce the window during which pre-built binaries are not available.
|
|
||||||
|
|
||||||
@c TODO: It would be good with badges on the website that tracks these
|
|
||||||
@c branches. Or maybe even a status page.
|
|
||||||
Generally, branches other than @code{master} are considered @emph{frozen} if
|
|
||||||
there has been a recent evaluation, or there is a corresponding @code{-next}
|
|
||||||
branch. Please ask on the mailing list or IRC if unsure where to place a
|
|
||||||
patch.
|
|
||||||
|
|
||||||
@item
|
|
||||||
@cindex determinism, of build processes
|
|
||||||
@cindex reproducible builds, checking
|
|
||||||
Check whether the package's build process is deterministic. This typically
|
|
||||||
means checking whether an independent build of the package yields the exact
|
|
||||||
same result that you obtained, bit for bit.
|
|
||||||
|
|
||||||
A simple way to do that is by building the same package several times in a
|
|
||||||
row on your machine (@pxref{Invoking guix build}):
|
|
||||||
|
|
||||||
@example
|
|
||||||
guix build --rounds=2 my-package
|
|
||||||
@end example
|
|
||||||
|
|
||||||
This is enough to catch a class of common non-determinism issues, such as
|
|
||||||
timestamps or randomly-generated output in the build result.
|
|
||||||
|
|
||||||
Another option is to use @command{guix challenge} (@pxref{Invoking guix
|
|
||||||
challenge}). You may run it once the package has been committed and built
|
|
||||||
by @code{@value{SUBSTITUTE-SERVER}} to check whether it obtains the same
|
|
||||||
result as you did. Better yet: Find another machine that can build it and
|
|
||||||
run @command{guix publish}. Since the remote build machine is likely
|
|
||||||
different from yours, this can catch non-determinism issues related to the
|
|
||||||
hardware---e.g., use of different instruction set extensions---or to the
|
|
||||||
operating system kernel---e.g., reliance on @code{uname} or @file{/proc}
|
|
||||||
files.
|
|
||||||
|
|
||||||
@item
|
|
||||||
When writing documentation, please use gender-neutral wording when referring
|
|
||||||
to people, such as @uref{https://en.wikipedia.org/wiki/Singular_they,
|
|
||||||
singular ``they''@comma{} ``their''@comma{} ``them''}, and so forth.
|
|
||||||
|
|
||||||
@item
|
|
||||||
Verify that your patch contains only one set of related changes. Bundling
|
|
||||||
unrelated changes together makes reviewing harder and slower.
|
|
||||||
|
|
||||||
Examples of unrelated changes include the addition of several packages, or a
|
|
||||||
package update along with fixes to that package.
|
|
||||||
|
|
||||||
@item
|
|
||||||
Please follow our code formatting rules, possibly running the
|
|
||||||
@command{etc/indent-code.el} script to do that automatically for you
|
|
||||||
(@pxref{Formatting Code}).
|
|
||||||
|
|
||||||
@item
|
|
||||||
When possible, use mirrors in the source URL (@pxref{Invoking guix
|
|
||||||
download}). Use reliable URLs, not generated ones. For instance, GitHub
|
|
||||||
archives are not necessarily identical from one generation to the next, so
|
|
||||||
in this case it's often better to clone the repository. Don't use the
|
|
||||||
@command{name} field in the URL: it is not very useful and if the name
|
|
||||||
changes, the URL will probably be wrong.
|
|
||||||
|
|
||||||
@end enumerate
|
|
||||||
|
|
||||||
When posting a patch to the mailing list, use @samp{[PATCH] @dots{}} as a
|
|
||||||
subject. You may use your email client or the @command{git send-email}
|
|
||||||
command (@pxref{Sending a Patch Series}). We prefer to get patches in plain
|
|
||||||
text messages, either inline or as MIME attachments. You are advised to pay
|
|
||||||
attention if your email client changes anything like line breaks or
|
|
||||||
indentation which could potentially break the patches.
