minimal native desktop shader editor written in zig. uses wgpu-native c api directly and glfw for windowing

zig build run

once running, a colorful triangle will render. leave the window open. open shader.wgsl and start editing.

• type in the left panel to edit WGSL
• arrow keys to navigate
• enter for new lines, backspace to delete
• ctrl+s to compile — preview updates on success, red error panel on failure
• last valid shader keeps rendering if compilation fails

if you write a syntax error, the console will print === webgpi compilation error ===, and the window will safely keep animating the old shader without crashing.
