Abstract
This document describes the Docutils odtwriter.
What it does -- rst2odt.py/odtwriter.py translates reST (reStructuredText) into a Open Document Format .odt file. You can learn more about the ODF format here:
You should be able to open documents (.odt files) generated with rst2odt.py in OpenOffice/oowriter. I use OpenOffice version 2.0 in my testing.
The distribution file is here: source distribution of ODF/ODT writer for Docutils.
odtwriter is also available via Subversion from the Docutils repository under docutils/sandbox/dkuhlman/OpenDocument/. The following will download Docutils including odtwriter and associated files into your current directory:
$ svn checkout svn://svn.berlios.de/docutils/trunk docutils
For more information about access to the Docutils Subversion repository, see: http://docutils.sourceforge.net/docs/dev/repository.html.
odtwriter requires:
Python
A sufficiently recent version of Docutils.
Either of the following:
odtwriter will try first to use Lxml, and if it is not installed will use ElementTree.
Optional -- Pygments is required for syntax highlighting of code in literal blocks. See section Syntax highlighting.
Install odtwriter with the standard Python installation commands:
$ python setup.py build $ python setup.py install # possibly as root
This will install rst2odt.py in your bin directory and the odtwriter and the styles file under docutils/writers/odtwriter within your Docutils installation.
Run it from the command line as follows:
$ rst2odt.py myinput.txt myoutput.odt
To see usage information and to learn about command line flags that you can use, run the following:
$ rst2odt.py --help
Examples:
$ rst2odt.py -s -g python_comments.txt python_comments.odt $ rst2odt.py --source-url=odtwriter.txt --generator --stylesheet-path=/myconfigs/styles.odt odtwriter.txt odtwriter.odt
The following command line flags are specific to odtwriter:
--stylesheet=<URL> | |
Specify a stylesheet URL, used verbatim. Overrides --stylesheet-path. | |
--stylesheet-path=<file> | |
Specify a stylesheet file, relative to the current working directory. The path is adjusted relative to the output ODF file. Overrides --stylesheet. Default: "/usr/local/lib/python2.5/site- packages/docutils/writers/odtwriter/styles.odt" | |
--cloak-email-addresses | |
Obfuscate email addresses to confuse harvesters while still keeping email links usable with standards- compliant browsers. | |
--table-border-thickness=TABLE_BORDER_THICKNESS | |
Specify the thickness of table borders in thousands of a cm. Default is 35. | |
--add-syntax-highlighting | |
Add syntax highlighting in literal code blocks. Default is no. Requires installation of Pygments. |
odtwriter uses a number of styles that are defined in the default styles.xml. This section describes those styles.
You can modify the look of documents generated by odtwriter in several ways:
Open (a copy of) styles.odt in OpenOffice/oowriter and modify the style you wish to change. Now, save this document, then generate your documents using this modified copy of styles.odt.
In my version of oowriter, to modify styles, either (1) press F11 or (2) use menu item "Format/Styles and Formatting", then right-click on the relevant style and select "Modify". Modify the style, then save your document.
Open a document generated by odtwriter in oowriter`. Now, edit the style you are interested in modifying. Now, you can extract the styles.xml file from your document and either (1) use this as your default styles file or (2) copy and paste the relevant style definition into your styles.xml.
Extract styles.xml from styles.odt using your favorite zip/unzip tool. Then modify styles.xml with a text editor. Now re-zip it back into your own styles.odt, or use it directly by specifying it with a command line flag. Hint: If you intend to extract styles.xml from an .odt file (and then "re-zip" it), you should turn off XML optimization/compression in oowriter. In order to this in oowriter, use Tools --> Options... --> Load-Save --> General and turn off "Size optimization for XML format".
Open an empty (or new) document in oowriter. Define the styles described in this section. Then, use that document (a .odt file) as your stylesheet. odtwriter will extract the styles.xml file from that document and insert it into the output document.
Some combination of the above.
This section describes the styles used by odtwriter.
Note that we do not describe the "look" of these styles. That can be easily changed by using oowriter to edit the document styles.odt (or a copy of it), and modifying any of the styles described here.
To change the definition and appearance of these styles, open styles.odt in oowriter and open the Styles and Formatting window by using the following menu item:
Format --> Styles and Formatting
Then, click on the Paragraph Styles button or the Character Styles button at the top of the Styles and Formatting window. You may also need to select "All Styles" from the drop-down selection list at the bottom of the Styles and Formatting window in order to see the styles used by odtwriter.
Notice that you can make a copy of file styles.odt, modify it using oowriter, and then use your copy with the --stylesheet-path=<file> command line option. Example:
$ rst2odt.py --stylesheet-path=mystyles.odt test2.txt test2.odt
Table styles are generated by oowriter for each table that you create. Therefore, odtwriter attempts to do something similar. These styles are created in the content.xml document in the generated .odt. These styles have names prefixed with "rststyle-Table".
odtwriter can generate an outline style table of contents. However, if you want an oowriter style table of contents along with the formatting control that oowriter gives you, then you may want to omit the .. contents:: directive and, after generating your document, open it in oowriter and insert a table of contents. That feature is under menu item:
Insert --> Indexes and Tables --> Indexes and Tables
odtwriter can add Python syntax highlighting to code in literal code blocks. In order to activate this, do both of the following: (1) install Pygments and (2) use the command line flag --add-syntax-highlighting. Example:
$ rst2odt.py -g --add-syntax-highlight test.txt test.odt
Caution: When odtwriter does syntax highlighting, by default, it applies a Python lexer and Python syntax highlighting. If you have literal code blocks that contain code which is not Python code, then you likely to want either (1) to use the .. sourcecode:: directive to change the language/lexer or to turn off highlighting across sections of your document or (2) to not use the --add-syntax-highlighting flag.
You can find Pygments here: Pygments.
The following styles are defined in styles.odt and are used for literal code blocks and syntax highlighting:
Each of the above styles has a default appearance that is defined in styles.odt. To change that definition and appearance, open styles.odt in oowriter and use menu item:
Format --> Styles and Formatting
Then, click on the Paragraph Styles button or the Character Styles button at the top of the Styles and Formatting window. You may also need to select "All Styles" from the drop-down selection list at the bottom of the Styles and Formatting window.
By default, when you use the --add-syntax-highlighting command line flag, syntax highlighting in literal blocks is on and the Python lexer is used. You can change this within your reST document with the following directive:
.. sourcecode newstate
or:
.. sourcecode lexer
where:
Examples:
.. sourcecode:: on .. sourcecode:: python .. sourcecode:: off .. sourcecode:: java .. sourcecode:: on
A few additional notes and hints:
There is limited support for the container directive. The limitations are the following:
So, for example:
.. container:: style-1 style-2 style-3 a block of text
Only style-1 is used; style-2 and style-3 are ignored. And, style-1 must be a paragraph style.
To define a paragraph style, use the following menu item:
Format --> Styles and Formatting
Then, click on the Paragraph Styles button.
The table directive can be used to add a title to a table. Example:
.. table:: A little test table =========== ============= Name Value =========== ============= Dave Cute Mona Smart =========== =============
The above will insert the title "A little test table" at the top of the table. You can modify the appearance of the title by modifying the paragraph style rststyle-table-title.
