<para><xref linkend='ex-buildGoPackage'/> is an example expression using buildGoPackage,

the following arguments are of special significance to the function:

|
|
|
|
<callout arearefs='ex-buildGoPackage-1'>
|
|
<para>
|

<varname>goPackagePath</varname> specifies the package's canonical Go import path.

<para>

<varname>subPackages</varname> limits the builder from building child packages that

have not been listed. If <varname>subPackages</varname> is not specified, all child
|
|
packages will be built.
|

</para>
|

<para>

In this example only <literal>code.google.com/p/go.net/ipv4</literal> and
|
|
<literal>code.google.com/p/go.net/ipv6</literal> will be built.

<para>

<varname>goPackageAliases</varname> is a list of alternative import paths
|
|
that are valid for this library.

Packages that depend on this library will automatically rename
|
|
import paths that match any of the aliases to <literal>goPackagePath</literal>.

In this example imports will be renamed from

<literal>golang.org/x/net</literal> in every package that depend on the
|
|
<literal>go.net</literal> library.

<para>

<varname>propagatedBuildInputs</varname> is where the dependencies of a Go library are

listed. Only libraries should list <varname>propagatedBuildInputs</varname>. If a standalone

|
program is being built instead, use <varname>buildInputs</varname>. If a library's tests require

additional dependencies that are not propagated, they should be listed in <varname>buildInputs</varname>.

If <varname>disabled</varname> is <literal>true</literal>,

nix will refuse to build this package.

In this example the package will not be built for go 1.3. The <literal>isGo13</literal>
|

is an utility function that returns <literal>true</literal> if go used to build the

|
package has version 1.3.x.

Reusable Go libraries may be found in the <varname>goPackages</varname> set. You can test
|
|
build a Go package as follows:
|
|
|
|
<screen>
|
|
$ nix-build -A goPackages.net
|
|
</screen>
|
|
|
|
</para>
|
|
|
|
<para>
|
|
You may use Go packages installed into the active Nix profiles by adding
|
|
the following to your ~/.bashrc:
|
|
|
|
<screen>
|
|
for p in $NIX_PROFILES; do
|
|
GOPATH="$p/share/go:$GOPATH"
|
|
done
|
|
</screen>
|
|
</para>
