Xml2rfc generates RFCs and IETF drafts from document source in XML according to the dtd in RFC2629.

Project description

Introduction

The IETF uses a specific format for the standards and other documents it publishes as RFCs, and for the draft documents which are produced when developing documents for publications. There exists a number of different tools to facilitate the formatting of drafts and RFCs according to the existing rules, and this tool, xml2rfc, is one of them. It takes as input an xml file which contains the text and meta-information about author names etc., and transforms it into suitably formatted output. The input xml file should follow the DTD given in RFC2629 (or it’s inofficial successor).

The current incarnation of xml2rfc provides output in the following formats: Paginated and unpaginated ascii text, html, nroff, and expanded xml. Only the paginated text format is currently (January 2013) accepable as draft submissions to the IETF.

Installation

Installation of the python package is done as usual with ‘pip install xml2rfc’, using appropriate switches and/or sudo.

Installation of support libraries for the PDF-formatter

In order to generate PDFs, xml2rfc uses the WeasyPrint module, which depends on external libaries that must be installed as native packages on your platform, separately from the xml2rfc install.

First, install the Cairo, Pango, and GDK-PixBuf library files on your system. See installation instructions on the WeasyPrint Docs:

https://weasyprint.readthedocs.io/en/stable/install.html

(Python 3 is not needed if your system Python is 2.7, though).

(On some OS X systems with System Integrity Protection active, you may need to create a symlink from your home directory to the library installation directory (often /opt/local/lib):

ln -s /opt/local/lib ~/lib

in order for weasyprint to find the installed cairo and pango libraries. Whether this is needed or not depends on whether you used macports or homebrew to install cairo and pango, and the homebrew / macport version.)

Next, install the pycairo and weasyprint python modules using pip. Depending on your system, you may need to use ‘sudo’ or install in user-specific directories, using the –user switch. On OS X in particular, you may also need to install a newer version of setuptools using –user before weasyprint can be installed. If you install with the –user switch, you may need to also set PYTHONPATH, e.g.,

PYTHONPATH=/Users/henrik/Library/Python/2.7/lib/python/site-packages

for Python 2.7.

The basic pip commands (modify as needed according to the text above) are:

pip install ‘pycairo>=1.18’ ‘weasyprint<=0.42.3’

With these installed and available to xml2rfc, the –pdf switch will be enabled.

For PDF output, you also need to install the Noto font set. Download the full set from https://noto-website-2.storage.googleapis.com/pkgs/Noto-unhinted.zip, and install as appropriate for your platform.

Usage

xml2rfc accepts a single XML document as input and outputs to one or more conversion formats.

Basic Usage: xml2rfc SOURCE [options] FORMATS...

Changelog

Version 2.16.0 (22 Dec 2018)

This release provides support for generation of xml2rfc PDF output. However, a default pip install will only install the xml2rfc module itself; additional installation work is needed to enable PDF generation:

pip install ‘pycairo>=1.18’ ‘weasyprint<=0.42.3’

With these installed and available to xml2rfc, the –pdf switch will be enabled.

For correct PDF output, you also need to install the Noto font set. Download the full set from:

and install as appropriate for your platform.

Version 2.15.5 (21 Dec 2018)

  • Added code to look for input marked as v3, and process that as v3 without requiring an explicit –v3 switch. This should make it easier to transition to v3 draft submissions.
  • Fixed a bug related to cref handling. Fixes issue #389.
  • Ensured propagation of options to parser and url resolver, and improved the error message for externals without .xml extension that give 404.
  • Fixed an include without explicit extension in a test input file, in order to work with the stricter v3 formatter include processing.

Version 2.15.4 (18 Dec 2018)

  • Tweaked the mkrelease script to prevent inclusion of temporary editor files.
  • Fixed a problem with string vs byte for referece file output.
  • Added a limitation on the intervaltree requirements to avoid a broken version.
