sphinxcontrib.paverutils

This module provides an alternative integration of Sphinx and Paver. It supports calling Sphinx from within Paver using multiple configurations, and does not assume you only want to build HTML output.

Basic Usage

To use this module, import it in your pavement.py file as from sphinxcontrib import paverutils, then define option Bundles for "html" and/or "pdf" output using the options described in the task help.

For example:

import paver
import paver.misctasks
from paver.path import path
from paver.easy import *
import paver.setuputils
paver.setuputils.install_distutils_tasks()
try:
    from sphinxcontrib import paverutils
except:
    import warnings
    warnings.warn('sphinxcontrib.paverutils was not found, you will not be able to produce documentation')

options(
    setup=Bunch(
        name = 'MyProject',
        version = '1.0',

        # ... more options here ...
        ),

    # Defaults for sphinxcontrib.paverutils
    sphinx = Bunch(
        docroot='.',
        sourcedir='docsource',
        builder='html',
    ),

    # One configuration to build HTML for the package
    html=Bunch(
        builddir='docs',
        confdir='sphinx/pkg',
    ),

    # Another configuration with different templates
    # to build HTML to upload to the website
    website=Bunch(
        builddir = 'web',
        confdir='sphinx/web',
    ),

    # We also want a PDF file for the website,
    # so the instructions are included in the web
    # configuration directory.
    pdf=Bunch(
        builddir='web',
        builder='latex',
        confdir='sphinx/web',
    ),

)

Tasks

After you have imported sphinxcontrib.paverutils in your pavement.py file, Paver will show two additional tasks. html takes the place of the task defined in paver.doctools and can be used to build HTML output. pdf uses the LaTeX builder and an external toolset such as TeXLive to create a PDF manual.

Configuration Parameters

docroot

the root under which Sphinx will be working.

default: docs

builddir

directory under the docroot where the resulting files are put.

default: build

sourcedir

directory under the docroot for the source files

default: "" (empty string)

doctrees

the location of the cached doctrees

default: $builddir/doctrees

confdir

the location of the sphinx conf.py

default: $sourcedir

outdir

the location of the generated output files

default: $builddir/$builder

builder

the name of the sphinx builder to use

default: html

template_args

dictionary of values to be passed as name-value pairs to the HTML builder

default: {}

Advanced Usage

You can also develop your own tasks by calling run_sphinx() directly:

@task
@needs(['cog'])
@cmdopts([
    ('in-file=', 'b', 'Blog input filename'),
    ('out-file=', 'B', 'Blog output filename'),
])
def blog(options):
    """Generate the blog post version of the HTML for the current module.
    """
    # Generate html from sphinx
    paverutils.run_sphinx(options, 'blog')

    blog_file = path(options.blog.outdir) / options.blog.out_file
    dry("Write blog post body to %s" % blog_file,
        gen_blog_post,
        outdir=options.blog.outdir,
        input_base=options.blog.in_file,
        blog_base=options.blog.out_file,
        )

    if 'EDITOR' in os.environ:
        sh('$EDITOR %s' % blog_file)
    return

Cog Extensions

In addition to the html and pdf tasks, the package includes the function run_script() to be used with cog to insert the output of a command line program in your documentation.

This example of reStructuredText source using run_script():

.. {{{cog
.. cog.out(run_script(cog.inFile, 'anydbm_whichdb.py'))
.. }}}
.. {{{end}}}

renders to:

.. {{{cog
.. cog.out(run_script(cog.inFile, 'anydbm_whichdb.py'))
.. }}}

::

    $ python anydbm_whichdb.py
    dbhash

.. {{{end}}}

The lines prefixed with .. are comments, and do not appear in the final HTML or PDF output.

Arguments:

input_file

The name of the file being processed by cog. Usually passed as cog.inFile.

script_name

The name of the Python script living in the same directory as input_file to be run. If not using an interpreter, this can be a complete command line. If using an alternate interpreter, it can be some other type of file.

interpreter='python'

The external interpreter to use for the program. Specify 'python', 'python3', 'jython', etc.

include_prefix=True

Boolean controlling whether the :: prefix is included. When chaining multiple commands together, the first instance would typically use the default and subsequent calls would use False.

ignore_error=False

Boolean controlling whether errors are ignored. If not ignored, the error is printed to stdout and then the command is run again with errors ignored so that the output ends up in the cogged file.

trailing_newlines=True

Boolean controlling whether the trailing newlines are added to the output. If False, the output is passed to rstrip() then one newline is added. If True, newlines are added to the output until it ends in 2.

break_lines_at=0

Integer indicating the length where lines should be broken and continued on the next line. Defaults to 0, meaning no special handling should be done.

line_break_mode='break'

Mode to control how the line breaks are inserted. Options are:

'break'

Insert the newline.

'wrap'

Use the textwrap module to wrap each line individually to the specified width.

'fill'

Use the textwrap module to wrap each line individually, inserting an appropriate amount of whitespace to keep the left edge of the lines aligned.

'continue'

Insert a backslash (\) and then a newline to break the line.

'truncate'

Break the line at the indicated location and discard the remainder.

Note

PyMOTW makes heavy use of this function, with several variations in arguments, so refer to the source there for more examples if you need them.

Users

PyMOTW

The Python Module of the Week package is built using Paver and Sphinx, including three forms of HTML and a PDF.

virtualenvwrapper

The documentation for virtualenvwrapper includes the packaged HTML and a website using alternate templates.

History

1.6

• include tox.ini in source dist
• adjust interpreter for python3
• redefine cog to allow it to run on specific input file(s)
• compatibility with paver 1.2, and add support force a full build

1.5

Misc.

1.4

• Add different modes for breaking lines in the output of run_script().
• Incorporate a fix from Maciek Starzyk for issue #6 so docroot can be set to something other than ..

1.3

Added simple line-splitting to run_script().

1.2

Modified run_script() so that if ignore_error is False any exception caused by the external application is re-raised. This "breaks" a build if there is a problem generating the cog output in an rst file, and makes it easier to spot problems with the cog instructions.

1.1

Updated to include run_script() function.

1.0

First public release based on the versions of these functions developed for PyMOTW.
