===============
About Locker
------------
Locker is a screensaver.
It can be extended through authentication backends, additional animations, and
general-purpose plug-ins.
Locker is part of the DeforaOS Project, found at https://www.defora.org/.
Compiling Locker
-----------------
Locker depends on the following components:
* Gtk+ 2.4 or later, or Gtk+ 3.0 or later
* DeforaOS libDesktop
* an implementation of `make`
* gettext (libintl) for translations
* DocBook-XSL for the manual pages
* GTK-Doc for the API documentation
With these installed, the following command should be enough to compile and
install Locker on most systems:
$ make install
To install (or package) Locker in a different location, use the `PREFIX` option
as follows:
$ make PREFIX="/another/prefix" install
Locker also supports `DESTDIR`, to be installed in a staging directory; for
instance:
$ make DESTDIR="/staging/directory" PREFIX="/another/prefix" install
The compilation process supports a number of other options, such as OBJDIR for
compilation outside of the source tree for instance.
On some systems, the Makefiles shipped may have to be re-generated accordingly.
This can be performed with the DeforaOS configure tool.
Documentation
-------------
Manual pages for each of the executables installed are available in the `doc`
folder. They are written in the DocBook-XML format, and need libxslt and
DocBook-XSL to be installed for conversion to the HTML or man file format.
Likewise, the API reference for Locker (plug-ins) is available in the
`doc/gtkdoc` folder, and is generated using gtk-doc.
Extending Locker
----------------
Plug-ins for the Locker program can be written according to the API definitions
installed and found in `<Desktop/Locker/*.h>` (in the source code in the
`include/Locker/*.h` files).
Sample plug-ins can be found in `src/auth/template.c`, `src/demos/template.c`,
and `src/plugins/template.c`.
Further plug-ins may also be found in the
[DeforaOS Integration](https://www.defora.org/os/project/4339/Integration)
project.
