Move your cursor to any line in your code and hit the preview button – instantly see what that line renders!

5
🖱️ Tweak custom images or data

Click on input details in the preview pane to swap in your own pictures or numbers for testing.

6
🔄 Watch it update live

Move your cursor around or make changes – the preview refreshes smoothly without slowing you down.

✅ Debug shaders visually

Now you spot issues instantly with beautiful live images right in your editor, making graphics coding fun and fast.

What is shaderdebug.nvim?

shaderdebug.nvim is a Lua Neovim plugin for live line previews of Slang fragment shaders—hover your cursor on any return or assignment line, and it renders the output as a quad inline. This GitHub WIP app solves tedious shader debugging by showing results instantly without leaving the editor, using Slang reflection to detect textures, samplers, and buffers. Bind custom images via :ShaderDebugSetImage or JSON data interactively, with Vulkan or headless OpenGL backends.

Why is it gaining traction?

It stands out with non-blocking auto-preview on cursor moves (:ShaderDebugToggleAuto), turning shader iteration into a fluid loop—no full rebuilds needed. Interactive preview pane lets you click inputs to edit paths or data, refresh with 'r', or clear with 'x'. For a new WIP Slang tool, the reflection-driven inputs and inline image.nvim display hook devs chasing that "wip slang meaning" instant feedback.

Who should use this?

Vulkan or graphics engineers writing Slang fragments in Neovim, debugging line-by-line without engine spins. Perfect for shader artists prototyping effects or HLSL migrants checking outputs visually. Skip if you're not on Neovim 0.10+ with slangc and image.nvim.

Verdict

Worth a spin for Slang/Neovim users—solid README with commands and a :ShaderDebugOpenTestShader lowers the barrier despite 19 stars and 1.0% credibility score signaling WIP immaturity. Polish the OpenGL path and add tests to escape GitHub WIP label limbo.
