[screensavers] / screenhack / README.md

Overview
========

The files in this directory comprise the `screenhack` API/library which is part
of [xscreensaver](https://www.jwz.org/xscreensaver/). They are collected here
in order to facilitate building the hacks contained in this repository without
requiring an xscreensaver source tree and build system.


Status
======

All files were extracted from the `xscreensaver-5.45.tar.gz` source tarball and
remain unmodified.

Since this directory only contains the files related to building X11 hacks
utilizing the `screenhack` API, if you need the `xlockmore` API or OpenGL
related files, either build your hack inside the xscreensaver source tree or
copy the relevant files into this directory; the various makefiles are
configured to automatically detect and compile them.


Instructions
============

For an example of use, see the top-level directory `reference/` in this
repository. It contains the `greynetic` hack, already configured to build
against this `screenhack` library, as well as `README.hacking`, a guide to
writing hacks against the `screenhack` library.

Although all the hacks in this repo contain `#define`s hardcoded for FreeBSD,
since all the `screenhack` files are unmodified, they all contain the various
preprocessor trickery for building on other platforms. If you're having trouble
figuring out the correct set of `#define`s for building on your system, try
extracting the xscreensaver source, running `./configure`, and examining the
`#define`s contained in the generated `config.h`.
