Free simple directmedia layer software for linux

OSDL project has for goal to provide a free portable high-level open-source library for multimedia and game programming. It is based upon low level graphical backends, notably Sam Lantingas SDL, which means Simple DirectMedia Library.
OSDL is a C++ framework built currently on top of SDL, thus OSDL stands for Objet oriented Simple DirectMedia Library.
OSDL makes use of the Ceylan library, the place where we gathered all generic developments needed by OSDL.
OSDL is also strongly linked with our project dedicated to the creation of an open-source gaming console, Once Sol. More generally speaking, one may take a look at our project portal, Esperide, which gathers all we are doing in the video game field.
At first, most people are primarily interested in screenshots, then in the OSDL API, finally in the recommended way of getting OSDL, which is named LOANI.
This is still an early stage of OSDLs development, so little information is to be found on this website. We nevertheless hope it will get bigger and bigger, as the source code grows. We advise you to look at the column we named Documentation, since many interesting articles about game creation lie there.
Enhancements:
- SVN used instead of CVS
- The Autotools are used, instead of custom-made GNUMakefiles
- integration to the Ceylan 0.5 version
- OSDL scheduler robustified and enhanced a lot
- numerous tests improved (full test suite added), and many bugs fixed

Simple Spreadsheet is a webbased spreadsheet program written in Javascript, HTML, CSS and PHP.

Simple Spreadsheet features formulas, charts, numeric formats, keyboard navigation, etc. Javascript is used for the default data format and for the macros and formulas.

The CAN Abstraction Layer (CANAL) provides a single interface for programs to use different CAN drivers.
It consists of a CANAL daemon that handles client and driver communication, a canalLogger that logs messages in a window, and a simple diagnostic application. C++ clases and DLL/DL interfaces are provided.
Enhancements:
- The configuration readings for CanalWorks were upgraded.
- A GUID ordering problem in canald was fixed.
- A problem with clear message list switch in CanalWorks was fixed.
- A problem in which Linux version Level I received a thread with an invalid count returned for DataAvailable was fixed.

Filter::Simple::Compile is a drop-in replacement to Filter::Simple.

SYNOPSIS

Drop-in replacement for Filter::Simple:
package MyFilter;
use Filter::Simple::Compile;
FILTER { ... };

This way also works:
use Filter::Simple::Compile sub { ... };

This module lets you write Module::Compile extensions that are compatible with Filter::Simples API.

Additionally, no Filter::Simple::Compile does the same thing as use Filter::Simple::Compile, except the meaning for use and no will be reversed for your filter:

package MyFilter;
no Filter::Simple::Compile sub { ... }

# "no MyFilter" begins filtering
# "use MyFilter" terminates it

Simple Invoices is a clean, simple, and basic Web-based invoicing system.

Simple Invoices is meant for personal invoices, home office invoicing, small organization invoicing, and basic POS (point of sale) systems for light usage.

Its goals are to be easy to use, simple and clean, and focused on its task. It is not meant for heavy-use POS applications, nor is it meant to be enterprise ready.

Simple Blue is a modified Sunergos Blue theme with user list.

Lightweight (SVG), elegant, works with all languages and widescreen.

Database Independent Abstraction Layer for C (libdbi) implements a database-independent abstraction layer in C, similar to the DBI/DBD layer in Perl.
Writing one generic set of code, programmers can leverage the power of multiple databases and multiple simultaneous database connections by using this framework.
Main features:
Database-level abstraction:
Your programs dont need to deal with the arbitrary interfaces and oddities of each database library. libdbi handles all the details for you, you just tell it what you want the database to do.
Modularity:
Since database code written with libdbi is not tied to one specific database server, you can effortlessly switch databases or give your users the option to specify their own database settings.
Clean interface:
With ample documentation describing libdbi and its well thought out object-oriented design, programming with libdbi should be less painful than programming with native database libraries. And you only need to learn it once instead of learning each database librarys syntax.
Accommodates coder apathy:
libdbi is written to do The Right Thing(tm), not just some quick hack that does the job in a half-assed fashion. This saves tons of your $100/hour time from debugging, so that you can mess around having fun during the hours that clients are paying you to debug. It also strives to reduce the worldwide crisis of carpal tunnel syndrome, so it uses constructs such as this one to pack multiple function calls into one line, saving you the bother of typing more than you have to:
dbi_result_get_fields(result, "id.%i firstname.%s lastname.%s fractional_value.%f", &id, &firstname, &lastname, &floatval);
Driver interface:
The dynamic linking used by libdbi allows for driver authors to license their drivers however they please - they are not restricted to the GPL or LGPL. Drivers are easy to write, and require no special installation.
Error handling:
Instead of checking every single database call for errors, libdbi gives programmers the option of registering an error handler callback, similar to a signal handler. Because we know youll "forget" to check for errors otherwise :)
Convenience:
Spend your time writing clever code, not reinventing the wheel with your own single-use, #define-abusing, less featureful database interface.

The libdbi-drivers project maintains drivers for libdbi. Drivers are distributed seperately from the library itself.
There are currently drivers for MySQL, PostgreSQL, SQLite, and mSQL. More are on the way.
Enhancements:
- Support for a timezone suffix in time and date types was added.
- Error handling and error reporting were vastly improved.
- Some memory leaks were fixed.
