<title>Description</title>
<para>
Flatpak uses manifest, or recipe, files in a json or yaml format to describe how an
application and its bundled dependencies can be built from sources. The manifest
gets used by flatpak-builder.
</para>
</refsect1>
<refsect1>
<title>File format</title>
<para>
The top level of the manifest file describes global attributes of the application, how
it can be built, and the list of modules that need to be built.
</para>
<refsect2>
<title>Toplevel properties</title>
<para>
These are the properties that are accepted:
</para>
<variablelist>
<varlistentry>
<term><option>id</option> or <option>app-id</option> (string)</term>
<listitem><para>A string defining the application id.</para></listitem>
</varlistentry>
<varlistentry>
<term><option>branch</option> (string)</term>
<listitem><para>The branch of the application, defaults to master.</para></listitem>
</varlistentry>
<varlistentry>
<term><option>collection-id</option> (string)</term>
<listitem><para>The collection ID of the repository,
defaults to being unset. Setting a globally
unique collection ID allows the apps in the repository to be shared over
peer to peer systems without needing further configuration.
If building in an existing repository, the collection ID
must match the existing configured collection ID for that
repository.</para></listitem>
</varlistentry>
<varlistentry>
<term><option>extension-tag</option> (string)</term>
<listitem><para>If building an extension, the tag for the extension
point to use. Since flatpak 0.11.4 a runtime may define multiple
locations for the same extension point with the intention that
different branches for the extension are mounted at each location. When
building an extension it is necessary to know what extension point to
install the extension to. This option resolves any ambiguity
in which extension point to choose. If not specified, the default choice
is to install into either the only location for the extension point or
into the location for the untagged extension point. If there are multiple
locations for the same extension point defined with different tags
then an error will occur.</para></listitem>

<title>Build environment</title>
<para>
When building the application each command is run in a separate sandbox with access
to only the things required for it. This section describes the details of the sandbox.
Any options here can be overridden globally or per-module with the <option>build-args</option>
option (although such manifest will not work if you start flatpak-builder with <option>--sandbox</option>).
</para>
<refsect2>
<title>Filesystem</title>
<para>
Each module is built in its own build directory, stored in a sub directory called
<filename>build/$modulename-$count</filename> in the state dir (which is typically <filename>.flatpak-builder/</filename>).
Additionally there is a symlink <filename>build/$modulename</filename> to the latest version.
In order to generate reproducible builds this directory is also mounted as <filename>/run/build/$modulename</filename>
in the sandbox (or <filename>/run/build-runtime/$modulename</filename> when building runtimes).
This is used as current working directory for all build ops.
</para>
<para>
The destination directory for installation is accessible for writing at the place it will seen at runtime.
In the case of a regular application this will be /app. If building a runtime it will instead be /usr, and
when building an extension it will be at the extensionpoint directory somewhere below /app (for app extension)
or /usr (for runtime extensions).
</para>
<para>
Additionally the there will be (as needed, depending on what is building) read-only mounts of the sdk at /usr,
sdk extensions below that, and the application at /app. No other filesystem access is available.

<title>Permissions</title>
<para>
Builds have the --allow=devel and --allow=multiarch permissions that regular flatpak runs don't have by default. This allows
limits the syscall filtering that is normally done so development tools like debuggers work. Otherwise the build sandbox
is very limited, for example there is no network access.
