The detected file endings are: *.glsl *.vsh *.vert *.tcsh *.tcs *.tesh *.tes *.gsh *.geo *.geom *.fsh *.frag *.csh *.cs, but this list can easily get changed in line 4 of the XML.

This highlighting does not perform a full syntax check and assumes core profile code on GLSL 1.30 and later. Note how keywords get crossed out in case they are not supported by the #version declaration. See this comparison of the same (non functional) dummy code to get an impression:Ĭomparing the build-in syntax highlighter with this alternative. Marks the ‘special parameters’ inside of layout() declarations based on the GLSL version (those are not keywords according to the specs so they are not marked outside of a layout() declaration).Unsupported keywords, build-in variables and functions are marked as such based on the detected GLSL version (see gif below).Detects the shader version per file based on the #version definition!.Support for desktop OpenGL up to 4.3 (with all keywords, build-in functions, constants and variables), as well as OpenGL ES 2.0 and OpenGL ES 3.0 (and WebGL as it uses ES 2 shaders).The definition has the following features: Add a new language syntax definition, look at Preferences->Text Editor->Generic Highlighter, you will see a location where QTCreator expects the XML file (~/.config/Nokia/qtcreator/generic-highlighter on OS X and Linux).Don’t forget the MIME-Types text/x-glsl-es-frag, text/x-glsl-es-geometry, text/x-glsl-es-vert, text/x-glsl-frag and text/x-glsl-vert! The handler can’t be changed, but the file endings – just remove them. Go to Preferences->Environment->MIME-Types in QTCreator and look for all types associated with GLSL ( application/x-glsl).So I was sick of waiting for better support and wrote a solution: The GLSL syntax checker in QTCreator is build-in, so it has to be deactivated first, then a syntax definition XML file in the format also used for Kate (and probably other KDE apps) can be used to define proper and modern GLSL: On the other hand, nothing indicates deprecated keywords and it can’t distinguish between the different GLSL variants. If you write shaders for OpenGL 3 (and later) or OpenGL ES 3, you will see a lot of red marks indicating errors in your code simply because QTCreator doesn’t know the latest keywords. The syntax highlighter in QTCreator for GLSL shaders is currently far from ideal: It’s basically stuck at OpenGL 2.1.
