AviSynth+ is an improved version of the AviSynth frameserver, with improved features and developer friendliness.
Visit our forum thread for compilation instructions and support. The original homepage of the project is not functional at the moment (June, 2018). Development branch: https://github.com/AviSynth/AviSynthPlus/tree/master
(note, that the bundled documentation was not following the numerous changes in Avisynth+. You can always check the online documentation at http://avisynth.nl/index.php/Main_Page)
AviSynth+'s documentation can be generated into HTML by using Sphinx.
Make sure that Sphinx is installed. This requires that Python is already installed and the pip tool is available. Sphinx 1.3 is the recommended version.
pip install sphinx
For various Linux distributions, a Sphinx package should be available in the distro's repositories. Often under the name 'python-sphinx' (as it is in Ubuntu's repositories).
There is currently a fallback so that distros that only provide Sphinx 1.2 can still build the documentation. It will look different than when built with Sphinx 1.3, because the theme used with Sphinx 1.3 (bizstyle) had not yet been added to the main Sphinx package.
Once Sphinx is installed, we can build the documentation.
cd distrib/docs/english
make html
CMake isn't really suited to doing header-only installs, so a GNUmakefile is provided specifically for this purpose.
make install
make install PREFIX=/path/to/location
make uninstall PREFIX=/path/to/location
