Build status:

This is The Next Generation of DocBook stylesheets in XSLT. It is a complete reimplementation of the stylesheets for transforming DocBook into modern, clean, semantically rich HTML. The presentation is supported by CSS and (if you wish, a small amount of) JavaScript. The expectation for paginated output is to use HTML+CSS.

The project home page is https://xsltng.docbook.org/. Documentation can be found in the DocBook xslTNG Reference. The latest release is probably the place to start.

Building the project, if you clone the repository, is described in Chapter 5. In brief, you’ll want to build the XSLT with gradle makeXslt and the jar file (for the extension functions) with gradle jar. You can build the whole distribution with gradle zipStage which will put all of the build artifacts in build/stage/zip.

If you want to build the release artifact yourself, several additional dependencies are required. Operating systems and package dependencies change over time. The instructions here were successfull in May, 2023. If you have trouble, please open an issue.

Install sass.

sudo apt-get update
sudo apt-get install libxml2-dev libxslt-dev
curl -o /tmp/dart.tar.gz -L https://github.com/sass/dart-sass/releases/download/1.56.0/dart-sass-1.56.0-linux-x64.tar.gz
cd /tmp && tar zxf dart.tar.gz && sudo mv dart-sass/sass /usr/local/bin

The libxml2-dev and libxslt-dev packages support additional Python packages described below.

brew install sass/sass/sass libxml2 libxslt 

The libxml2 and libxslt packages support additional Python packages described below.

choco install sass

You must have python3 installed and on your path. You must have the pygments and click modules installed:

python3 -m pip install pygments==2.14.0 click

You don’t have to have Pygments version 2.14.0 installed, but if you install a different version, you may find that some tests fail.

Testing the build requires a few more dependencies. The build will run run without them, but you won’t get accurate test results.

python3 -m pip install cython saxonche
python3 -m pip install --no-binary lxml html5-parser

I have been unable to find a way to install html5-parser on Windows.

If you don’t install all of the dependencies, or if you install a different version of Pygments, you may get some failing tests that you’d like to ignore.

To avoid having the whole build fail because of failing tests, run with the requireTestSuccess parameter set to false:

gradlew -PrequireTestSuccess=false …
