GLSL Shader editor is a software to edit and test shaderprograms for the OpenGL Shading Language (GLSL).
Since normally a pixel shader contains two files (vertex and fragment shader), these files will be handled and processed by the program as a single file (a shader).

For the further improvement of the easy handling of shaders, the software works on a complete directory so you can easy scan, edit and change all shaders in this directory with a simple mouse click. The editor implements syntax highlighting for all GLSL data types, function name and status values. The type of emphasis can be adjusted in the configuration of the software.

The shader created in the program can be tested for errors directly with the OpenGL implementation of you graphic card driver. As a special feature of the software, in contrast to other programs, the errors will not only be showed as text, instead they will be marked in the editor and you can jump directly to the error in the code with a mouse click.
