openstack-manuals-convert

Introduction

The Publican DocBook XML publishing tool applies relatively strict standards to the content and structure of input XML files. As such it has difficulty building documentation projects which have not been written from the ground up with Publican in mind, at least without some initial alteration.

openstack-manuals-convert is a script for taking DocBook XML from one such project and converting or rebasing it such that it can be built using Publican. The project in question is openstack-manuals which contains the XML for the documentation which appears on the http://docs.openstack.org site. The source XML is available here:

https://github.com/openstack/openstack-manuals

As openstack-manuals-convert is designed primarily for use with the guides contained in the openstack-manuals project it will not necessarily convert any and all guides to a format that is usable by Publican. Publicanize is however provided as a reference for some of the common issues you will face in performing such a conversion and possible solutions.

Prerequisites

  • Bash.

  • Publican 3.2.1+.

  • Saxon XSLT 2.0 processor.

  • ~/.publican.cfg file containing firstname, surname, and email information, This is used to generate a revision history entry.

    firstname: Shadow surname: Man email: shadowman@example.com

Building

To build openstack-manuals-convert:

$ git clone https://github.com/redhat-openstack/openstack-manuals-convert.git
$ cd ./openstack-manuals-convert
$ ./autogen.sh
$ make rpms

Installing

Use yum to install or reinstall the built package.

Running

To run openstack-manuals-convert:

$ git clone https://github.com/openstack/openstack-manuals.git
$ cd openstack-manuals/**GUIDE**
$ openstack-manuals-convert **[OPTIONS]**

By default the Publican-friendly version of the guide will be output to ./target/publican/.

                            --title="OpenStack User Guide"

Publican RFEs

These Publican RFEs have been raised, implementation of them will streamline the conversion and packaging process:

  • 893199 Add CSS to common-db5 for centering "author" tag (same styling as corpauthor in DocBook 4.5)
  • 953675 XSL for abstract and subtitle detection assumes info element is root node of XML file (not always the case when using info file directive).
  • 1004955 Publican print unused incorrectly detects files from higher levels in the directory structure (but within the book) as unused.

The issue with abstract detection (953675) prevents the use of Publican's package action. To work around this issue it is necessary to apply abstract.xsl.patch to /usr/share/publican/xsl/abstract.xsl like so:

$ sudo patch -p0 /usr/share/publican/xsl/abstract.xsl < abstract.xsl.patch
$ sudo patch -p0 /usr/share/publican/xsl/subtitle.xsl < subtitle.xsl.patch

It is anticipated that this action will no longer be required in future releases of Publican (4+).
