Lightweight Beancount support for VSCode. Zero runtime dependencies.

Features

Setting	Type	Default	Description
`beancountSprout.separatorColumn`	`number \\| null`	`null`	Align currencies at this column. `null` = auto-calculate.
`beancountSprout.insertCommas`	`boolean`	`true`	Insert thousand-separator commas when formatting.
`beancountSprout.fixedCJKWidth`	`boolean`	`false`	Treat CJK characters as double-width for alignment.

Add this to your VSCode settings to format automatically when saving:

"[beancount]": {
  "editor.formatOnSave": true
}

This extension builds upon the work of two existing open-source projects:

vscode-beancount by Lencerf (MIT License) — TextMate grammar for syntax highlighting
vscode-beancount-formatter by dongfg (MIT License) — Alignment algorithm
