`simvx.editor.panels.shader_editor`¶

Shader Editor Panel – GLSL code editor with live preview.

Provides a split-view shader editing experience: a CodeTextEdit with GLSL syntax highlighting on the left, and a material preview + error output on the right. Auto-recompiles the shader on text change (debounced 500ms after last edit) and displays compilation errors inline via TextMarker squiggles.

API¶

simvx.editor.panels.shader_editor.__all__¶: [‘ShaderEditorPanel’]

class simvx.editor.panels.shader_editor.GLSLHighlighter¶

Tokenizer that converts GLSL source lines into colored token spans.

Handles keywords, types, built-in functions/variables, comments (both // and /* */), preprocessor directives, numbers, and strings.

The tokenizer is stateful for multi-line /* */ comments.

Initialization

__slots__¶: (‘_in_block_comment’,)

reset()¶: Reset multi-line comment state.

tokenize_line(line: str) → list[tuple[str, str]]¶

Tokenize a single GLSL source line.

Returns: List of (text, token_type) pairs covering the entire line.

class simvx.editor.panels.shader_editor.ShaderPreview(**kwargs)¶

Bases: simvx.core.Control

Preview widget that displays a shaded sphere/cube/quad representation.

Since full Vulkan pipeline compilation requires the graphics backend, this preview uses a software-approximated sphere rendering with simulated lighting based on the shader’s apparent output.
