Free highly configurable code software for linux

Libqrencode is a C library for encoding data in a QR Code symbol, a kind of 2D symbology that can be scanned by handy terminals such as a mobile phone with CCD. The capacity of QR Code is up to 7000 digits or 4000 characters, and is highly robustness.
Libqrencode supports QR Code model 2, described in JIS (Japanese Industrial Standards) X0510:2004 or ISO/IEC 18004. Currently the following features are not supported:
- ECI and FNC1 mode
- Structured Append Feature
- Micro QR Code
- QR Code model 1

Spring-RCPs mission is to provide an elegant way to build highly-configurable, GUI-standards-following rich-client applications faster by leveraging the Spring Framework, and a rich library of UI factories and support classes.
The Spring Rich Client Project (RCP) is a sub-project of The Spring Framework. Spring-RCPs mission is to provide an elegant way to build highly-configurable, GUI-standards-following rich-client applications faster by leveraging the Spring Framework, and a rich library of UI factories and support classes. Initial focus is on providing support for Swing applications but a goal of Spring-RCP is to be view agnostic as much as possible.
Spring Rich Client Projects goal is to provide a viable option for developers that need a platform and a best-practices guide for constructing Swing applications quickly.
Specifically, spring-richclient seeks to:
Provide a way to build structured, highly-configurable, GUI-standards-following Swing applications faster by leveraging the Spring Framework.
Foster integration with existing rich-client-related projects where it make sense. For example, jgoodies-forms and TableLayout are two good layout managers. We dont need to develop another one.
Adhere to the principles set forth by the Spring Framework--programming to interfaces; the importance of sound OO design, documentation, and testing.
Main features:
- A command framework that provides centralized configuration of Swing actions and appropriate handler registration based on the current active view. Command configuration, as well as action bar contribution policies (to menus or toolbars), can be defined centrally and externalized in Spring bean defintiions.
- A forms data binding and validation framework, for connecting edits made in your UI controls with your domain model automatically--with as you type feedback.
- Support for multiple window management, page configuration, and view management. The concepts here are inspired by Eclipses perspective/view constructs. Views can be defined in the Spring container, associated with one or more pages, and a default page can be configured to be loaded at startup.
- Common support classes addressing various rich client requirements including: well formed dialogs, wizards, input validation (typing hints and validation results reporting), button bars,internationalization, image/icon caching, progress monitoring, UI threading (classes cleanly promoting responsive UIs), treetable/property sheet, table sorting/high-volume table updates, GUI standards builders/helpers, help/about, etc.
Spring-rich adds value for people needing to develop Swing applications and do so in a way that promotes consistent, well-designed, configurable Swing applications. The spring-rich developers strongly feel the old days of Swing apps not looking native and not being performant or web-accessible are gone with JDK1.4.2 and 1.5 and webstart.
It is our belief the only problem with Swing is that there are a limited number of higher-level abstractions available that assist in making the toolkit simpler and easier to use, and a limited number of design best practices. The goal of spring-richclient is to provide that.
Enhancements:
- [RCP-400] - jgoodies forms not included as spring-rich dependencies
- Regression bug: icons on MessageAreaPane didnt show up

ROX Filer is a fast and powerful graphical file manager.

It has full drag-and-drop support and background file operations, and is highly configurable.

Pretty Code Web is a syntax highlighter for publishing code, written in any programming language, to the web.
Written in php it uses syntax files separate from the main code to highlight a specified language.
Main features:
- Syntax highlighting for (potentially) any language.
- User defined syntax files.
- User defined colors
- Separate colors for:
- 6 Keyword Groups
- Text Strings
- Operators
- Block and Line Comments
- Bracket Characters

HTML Code Convert helps speed up the conversion of HTML code into different format including Java Script, JavaServer Pages, Microsoft ASP, PHP, Perl, Python, and the UNIX Shell. It is particularly useful in CGI scripting.
Enhancements:
- Colors and font selected in prefeferences box.
- Fixe bug with Quit button. First try to support accessibility.
- Updated schemas.

Personal Weblog is a PHP include file for adding a weblog to a home page. Personal Weblog is highly configurable and can be changed to fit any web page style.
Main features:
- Simple to install and easy to use
- Completely configurable through a web browser
- Entries are categorized by topic
- Search-able by topic, keywords and time
- Supports RSS (Rich Site Summary) for syndication
- Supports multiple weblogs within a single database
- Works under many different operating systems and PHP configurations
- Extensible
I consider the lack of user management, discussion forums and "slashboxes" a feature for a personal home page. A personal weblog should meld with your home page, not contain it as a subtopic. If you are after something more heavy duty to run a news/discussion site check out Geeklog or the original Slashcode.
For announcements or help with general Personal Weblog issues you can subscribe to the low traffic weblog-users mailing list. Feel free to keep sending feedback, bug reports and suggestions my way though.
