Aretino Chant Tools

A VS Code extension with language support and a live SVG preview for Aretino chant notation .aretino files.

Features

Live preview — open any .aretino file and a preview opens to the side, updating as you type.
EB Garamond bundled — the preview renders text in EB Garamond (variable weight + italic), bundled with the extension so it looks the same on every machine. A document may still override the font with %option: textFont=....
Zoom — toolbar buttons or Ctrl/Cmd + scroll. The print staff size is small, so the preview is magnified for legibility without changing layout.

Usage

Open a .aretino file — the preview opens automatically (toggle with the aretino.preview.autoOpen setting).
Or run Aretino: Open Preview to the Side (Ctrl+K V / Cmd+K V), or click the preview icon in the editor title bar.

Settings

Setting	Default	Description
`aretino.preview.autoOpen`	`true`	Open the preview automatically when an `.aretino` file is opened.
`aretino.preview.defaultZoom`	`1.4`	Initial preview magnification.

Development

npm install            # from the monorepo root
npm run build -w aretino-chant-tools   # bundle the webview
# then press F5 in VS Code with this folder open to launch an Extension Host

The webview bundle (dist/webview.js) is produced by esbuild.js; it inlines @aretino-chant/core. The extension host (src/) is plain CommonJS and is not bundled.
