Synthclipse
GLSL shader prototyping tool based on Eclipse IDE.
...It makes possible to fast develop all kinds of shaders: Fragment (FS), Vertex (VS), Geometry (GS), Tessellation (TS) and Compute (CS). Shader development can be done using, compatible with Fragmentarium and Shadertoy (but limited to FS and VS), Fragx shaders or by using fully featured JavaScript JSX scripts. The JSX API is consistent with WebGL but in fact exposes complete OpenGL 4+ API.
To install Synthclipse one can download prepacked Eclipse with Synthclipse feature (see "Files" section above) or update an existing Eclipse using the following Update Site: https://kamil-kolaczynski.github.io/synthclipse/update/
Prepacked version has one advantage: it has nice console logs coloring since it shipped with Grep Console plugin ( https://marketplace.eclipse.org/content/grep-console ) that is configured specially for Synthclipse logs.
