Free stylesheets software for linux

DocBook is an SGML/XML vocabulary that enables you to create document content in a presentation-neutral form that captures the logical structure of the content.

Using the DocBook stylesheets, you can publish DocBook content as HTML pages and PDF files and other formats, including man pages, HTML Help, and JavaHelp.

CStyleX project is a tool to generate documentation from XML interface definitions.
CStyleX is a documentation system that uses a ref.xsl and man.xsl XSLT transforms to convert an XML input file describing the interface of a module in a C library into both an HTML reference and man pages.
Multiple interface definitions are compiled into an API reference that looks roughly similar to Javas javadoc. Man pages use concise GNU style troff macros.
The author must create the XML input files.
The input files are not created from header files or source code.
Enhancements:
- All stylesheets have been updated. For the latest style sheets check libmbas docs/xml directory.

XMLStarlet is a set of command line utilities (tools) which can be used to transform, query, validate, and edit XML documents and files using simple set of shell commands in similar way it is done for plain text files using UNIX grep, sed, awk, diff, patch, join, etc commands.
This set of command line utilities can be used by those who deal with many XML documents on UNIX shell command prompt as well as for automated XML processing with shell scripts.
Main features:
- Check or validate XML files (simple well-formedness check, DTD, XSD, RelaxNG)
- Calculate values of XPath expressions on XML files (such as running sums, etc)
- Search XML files for matches to given XPath expressions
- Apply XSLT stylesheets to XML documents (including EXSLT support, and passing parameters to stylesheets)
- Query XML documents (ex. query for value of some elements of attributes, sorting, etc)
- Modify or edit XML documents (ex. delete some elements)
- Format or "beautify" XML documents (as changing indentation, etc)
- Fetch XML documents using http:// or ftp:// URLs
- Browse tree structure of XML documents (in similar way to ls command for directories)
- Include one XML document into another using XInclude
- XML c14n canonicalization
- Escape/unescape special XML characters in input text
- Print directory as XML document
- Convert XML into PYX format (based on ESIS - ISO 8879), and vice versa
XMLStarlet command line utility is written in C and uses libxml2 and libxslt from http://xmlsoft.org/.
Implementation of extensive choice of options for XMLStarlet utility was only possible because of rich feature set of libxml2 and libxslt (many thanks to the developers of those libraries for great work).
diff and patch options are not currently implemented. Other features need some work too. Please, send an email to the project administrator (see http://sourceforge.net/projects/xmlstar/) if you wish to help.
XMLStarlet is linked statically to both libxml2 and libxslt, so generally all you need to process XML documents is one executable file. To run XmlStarlet utility you can simple type xml on command line and see list of options available.
XMLStarlet is open source freeware under MIT license which allows free use and distribution for both commercial and non-commercial projects.

Resource Registries is a product for Plone used for linked style sheet files and javascripts.
A registry for linked Stylesheet files and Javascripts.
This registry is mainly aimed at solving the following usecases:
- Enable product authors to register stylesheets with their product installers without having to resort to override either header.pt or ploneCustom.css creating potential conflicts with other products.
- Enable more componentialization of the stylesheets provided with Plone (and other products) without having to increase the number of http requests for a Plone page.
- Enable condition checking on stylesheets. Great for variable look-and-feel for groups/roles/folders/departments/content-types/etc
- Enable inline dynamic stylesheets. For those style rules that should vary for each request. Mainly used for things like header-bar- backgroundimages, department colors etc.
- Enable developers to activate/deactivate their styles in a simpler way
- Enable compression to safe bandwidth and download time
Enhancements:
- Fixed encoding HTTP header for javascripts.

PRES project (the Press Release System) is a simple content management system, essentially targeted at producing a news and information site. Managing a PRES system is designed to be simple.
However, presentation is sophisticated and flexible. An elementary knowledge of IT would be useful but expertise in designing and managing websites is not a requirement. PRES can be used for anything from private blogging to corporate news systems.
Main features:
Flexible Presentation
- All content is generated as XML which is styled at server side with XSL-T stylesheets to provide the final look and feel of your pages. This permits an almost infinite variety of presentations. Furthermore, different XSL-T transforms can be associated with different categories, allowing you to have different styling for different parts of your site.
Caching
- Content is generated on request, but in order to limit the computational load on busy sites all content is cached for a limited period (by default twenty minutes).
Subscription
- PRES allows users to subscribe to categories - effectively sections of the site. When new stories are posted to a section youre subscribed to, you will automatically get email with a link to the story.
Syndication
- PRES makes its headlines available as a syndication feed, using both RSS 0.91 and RSS 1.0. This allows other news sites to automatically incorporate live headlines from a PRES site into their content.
Threaded Discussion
- PRES optionally allows registered users to add comments to stories in a threaded manner, similar to sites like Slashdot.
Moderation
- PRES optionally allows registered users to moderate other users comments.

CSSTidy is an opensource CSS parser and optimizer. The project is available as executeable file (available for Windows, Linux and OSX) which can be controlled per command line and as PHP script (both with almost the same functionality).
In opposite to most other CSS parsers, no regular expressions are used and thus CSSTidy has full CSS2 support and a higher reliability.
Main features:
- colours like "black" or rgb(0,0,0) are converted to #000000 or rather #000 if possible. Some hex-codes are replaced by their colour names if they are shorter.
- a{property:x;property:y;} becomes a{property:y;} (all duplicate properties are merged)
- margin:1px 1px 1px 1px; becomes margin:1px;
- margin:0px; becomes margin:0;
- a{margin-top:10px; margin-bottom:10px; margin-left:10px; margin-right:10px;} becomes a{margin:10px;}
- margin:010.0px; becomes margin:10px;
- all unnecessary whitespace is removed, depending on the compression-level
- all background-properties are merged
- all comments are removed
- the last semicolon in every block can be removed
- missing semicolons are added, incorrect newlines in strings are fixed, missing units are added, bad colors (and color names) are fixed
- property:value ! important; becomes property:value !important.
Why optimise?
If you optimise your CSS code you have faster loading pages and lower traffic costs. So both you and your visitors benefit from an optimisation. If you are interested in a faster loading webpage, websiteoptimization.com might also be an interesting resource.
Compression ratio
The compression ratio mostly depends on the level of whitespace-removal. Using standard whitespace-removal (which preserves the readability) the compression ratio often is 30% and more. In theory the compression ratio can be 99,99% but only very "stupid" stylesheets will allow those ratios. Also have a look at the examples.
Apart from compression
If a high compression is not important for you, you can also use CSSTidy to format or fix CSS code for a higher browser compatibility. Apart from the 4 default templates you can specify custom templates so that you can easily format a lot of CSS code using your own coding style. Other features are sorting and changing the case of selectors and properties.
Enhancements:
- Note: This is the last version of CSSTidy. If youd like continue maintaining it, let me know.
- FS#146 - Quotes
- FS#147 - Universal selector before classes, IDs and attribute selectors
- FS#150 - Wrong trasformation of a big integer value
- FS#144 ? !important rule
- FS#140: Fixing Values of Invalid properties
- [ 1745894 ] @media merge strangeness (cssTidy.exe version)
- FS#143: Save some more bytes

Simple DocBook Processor project reads a DocBook XML file, processes it into typeset pages, and outputs the result as PostScript (which can easily be converted to a PDF).
It is "simple" because it supports only a subset of DocBook, and also because it does not make use of a DTD or stylesheets or any other heavyweight apparatus. Simple DocBook Processor is a single program. SDoP is used to format the Exim reference manual.
Enhancements:
- A lot of new processing parameters have been added to make it possible to change the output formatting in many ways.
