# Extensions deinstalled with unopkg remove '''Must''' have a %postun of 'unopkg list --shared > /dev/null 2>&1' because the actual removal of files is deferred until the next start, so this ensures that this takes place under the control of your rpm on deinstallation.<BR>

Otherwise during registration of a packed .oxt with unopkg the package is automatically unzipped and the contents copied into a persistent cache directory. Using -link and an unpacked .oxt dir allows this additional copy to be omitted and importantly allows the rest of the standard rpmbuild tooling to determine additional autorequires for a package or find flaws that cannot be seen in the opaque zip case.<BR>

LibreOffice extension rpm guidelines

  1. Extensions Must be installed unpacked under %{_libdir}/libreoffice/extensions. These are termed bundled extensions. Extensions should not be installed as shared extensions i.e. via unopkg --shared
  2. An extension should normally just be able to just Require: an appropriate LibreOffice component e.g. libreoffice-core, without a specific n-v-r as extensions use the stable UNO abi which rarely changes, and then only to add extra apis. So unless you require a specific feature of a LibreOffice release there is no need to require a specific n-v-r and force a rebuild on every n-v-r of libreoffice.
  3. extensions Should be named libreoffice-FOO.
  4. extensions are similar to e.g. xorg video drivers in that there exist proprietary or binary only extensions, but of course normal Fedora rules apply to what extensions can be packaged, i.e. see normal packaging licensing etc. rules. The license Must be acceptable, and the package Must be built from source.
  5. extensions can be written in any language that has a uno binding, e.g. C++, python, java or StarBasic. Consider the additional packaging guidelines of the language that the extension is written in if such guidelines exists.

..
An example is...

%global extname writer2latex
Name:     libreoffice-%{extname}
Requires: libreoffice-core

%install
install -d -m 755 $RPM_BUILD_ROOT%{_datadir}/libreoffice/share/extensions/%{extname}
unzip -q target/lib/%{extname}.oxt -d $RPM_BUILD_ROOT%{_datadir}/libreoffice/share/extensions/%{extname}
