# Command list

> DynamicCommandList for terminal draw commands in otter-vte.

`DynamicCommandList` extends the render command model for terminal cells: backgrounds, glyph runs, powerline segments, underline styles.

```zig theme={null}
const vte = @import("otter_vte");

var cmds = vte.DynamicCommandList.init(allocator);
defer cmds.deinit();

// Record cell draws for the visible grid
// Attach TextSystem + ShapeScratch for RTL/CJK through otter-render
cmds.text_system = &text_system;
cmds.text_scratch = &scratch;
```

Reset or reuse the list each frame like `DefaultCommandList`. Terminal views often damage row bands instead of the full grid.

## Text shaping

When `text_system` and `text_scratch` are set, text commands use HarfBuzz shaping and font fallbacks from `otter-render`. Plain ASCII can omit them for the FreeType fast path.

## Playback

Rasterize with `otter-render` `quad_renderer`, passing terminal damage rects for row-level culling.
