Wkhtmltopdf python wrapper to convert html to pdf using the webkit rendering engine and qt
License: MIT

Bundled-Python-PDFKit
=====================

This is Python-PDFKit bundled with wkhtmltopdf, so you don't have to install it separately. Only works
on Gnu/Linux. Only tested on Debian. WKHTMLtoPDF is installed in your virtualenv, so it won't be available
system-wide.

To update the version of wkhtml... in this package, run the :code:`bundle.sh` script (change the version in
 it first).

Python 2 and 3 wrapper for wkhtmltopdf utility to convert HTML to PDF using Webkit.

This is adapted version of `ruby PDFKit <https://github.com/pdfkit/pdfkit>`_ library, so big thanks to them!

Installation
------------

1. Install python-pdfkit::

	$ pip install bundled-pdfkit  (or pip3 for python3)

2. Install wkhtmltopdf (no need to do that):

* Debian/Ubuntu::

	$ sudo apt-get install wkhtmltopdf
	
* macOS::

	$ brew install caskroom/cask/wkhtmltopdf

**Warning!** Version in debian/ubuntu repos have reduced functionality (because it compiled without the wkhtmltopdf QT patches), such as adding outlines, headers, footers, TOC etc. To use this options you should install static binary from `wkhtmltopdf <http://wkhtmltopdf.org/>`_ site or you can use `this script <https://github.com/JazzCore/python-pdfkit/blob/master/travis/before-script.sh>`_.

* Windows and other options: check wkhtmltopdf `homepage <http://wkhtmltopdf.org/>`_ for binary installers

Usage
-----

For simple tasks::

	import pdfkit

	pdfkit.from_url('http://google.com', 'out.pdf')
	pdfkit.from_file('test.html', 'out.pdf')
	pdfkit.from_string('Hello!', 'out.pdf')

You can pass a list with multiple URLs or files::

	pdfkit.from_url(['google.com', 'yandex.ru', 'engadget.com'], 'out.pdf')
	pdfkit.from_file(['file1.html', 'file2.html'], 'out.pdf')

Also you can pass an opened file::

    with open('file.html') as f:
        pdfkit.from_file(f, 'out.pdf')

If you wish to further process generated PDF, you can read it to a variable::

    # Use False instead of output path to save pdf to a variable
    pdf = pdfkit.from_url('http://google.com', False)

You can specify all wkhtmltopdf `options <http://wkhtmltopdf.org/usage/wkhtmltopdf.txt>`_. You can drop '--' in option name. If option without value, use *None, False* or *''* for dict value:. For repeatable options (incl. allow, cookie, custom-header, post, postfile, run-script, replace) you may use a list or a tuple. With option that need multiple values (e.g. --custom-header Authorization secret) we may use a 2-tuple (see example below).

::

	options = {
	    'page-size': 'Letter',
	    'margin-top': '0.75in',
	    'margin-right': '0.75in',
	    'margin-bottom': '0.75in',
	    'margin-left': '0.75in',
	    'encoding': "UTF-8",
	    'custom-header' : [
	    	('Accept-Encoding', 'gzip')
	    ]
	    'cookie': [
	    	('cookie-name1', 'cookie-value1'),
	    	('cookie-name2', 'cookie-value2'),
	    ],
	    'no-outline': None
	}

	pdfkit.from_url('http://google.com', 'out.pdf', options=options)

By default, PDFKit will show all ``wkhtmltopdf`` output. If you don't want it, you need to pass ``quiet`` option::

    options = {
        'quiet': ''
        }

    pdfkit.from_url('google.com', 'out.pdf', options=options)

Due to wkhtmltopdf command syntax, **TOC** and **Cover** options must be specified separately. If you need cover before TOC, use ``cover_first`` option::

	toc = {
	    'xsl-style-sheet': 'toc.xsl'
	}

	cover = 'cover.html'

	pdfkit.from_file('file.html', options=options, toc=toc, cover=cover)
	pdfkit.from_file('file.html', options=options, toc=toc, cover=cover, cover_first=True)

You can specify external CSS files when converting files or strings using *css* option.

**Warning** This is a workaround for `this bug <http://code.google.com/p/wkhtmltopdf/issues/detail?id=144>`_ in wkhtmltopdf. You should try *--user-style-sheet* option first.

::

    # Single CSS file
    css = 'example.css'
    pdfkit.from_file('file.html', options=options, css=css)

    # Multiple CSS files
    css = ['example.css', 'example2.css']
    pdfkit.from_file('file.html', options=options, css=css)

You can also pass any options through meta tags in your HTML::

	body = """
	    <html>
	      <head>
	        <meta name="pdfkit-page-size" content="Legal"/>
	        <meta name="pdfkit-orientation" content="Landscape"/>
	      </head>
	      Hello World!
	      </html>
	    """

	pdfkit.from_string(body, 'out.pdf') #with --page-size=Legal and --orientation=Landscape

Configuration
-------------

Each API call takes an optional configuration paramater. This should be an instance of ``pdfkit.configuration()`` API call. It takes the configuration options as initial paramaters. The available options are:

* ``wkhtmltopdf`` - the location of the ``wkhtmltopdf`` binary. By default ``pdfkit`` will attempt to locate this using ``which`` (on UNIX type systems) or ``where`` (on Windows).
* ``meta_tag_prefix`` - the prefix for ``pdfkit`` specific meta tags - by default this is ``pdfkit-``

Example - for when ``wkhtmltopdf`` is not on ``$PATH``::

    config = pdfkit.configuration(wkhtmltopdf='/opt/bin/wkhtmltopdf')
    pdfkit.from_string(html_string, output_file, configuration=config)


Troubleshooting
---------------

- ``IOError: 'No wkhtmltopdf executable found'``:

  Make sure that you have wkhtmltopdf in your `$PATH` or set via custom configuration (see preceding section). *where wkhtmltopdf* in Windows or *which wkhtmltopdf* on Linux should return actual path to binary.

- ``IOError: 'Command Failed'``

  This error means that PDFKit was unable to process an input. You can try to directly run a command from error message and see what error caused failure (on some wkhtmltopdf versions this can be cause by segmentation faults)
