Rainbow Brackets for Obsidian

Makes nested brackets readable in plain Markdown text — like rainbow brackets in VS Code.

• Colors by depth — (), [] and {} are colored by nesting level (4 colors, cycling). Both brackets of a pair share a color.
• Pair at the cursor — the bracket next to the cursor and its match get a highlight.
• Unmatched brackets — shown in red with a wavy underline. In [ ( ] only the ( is flagged.

Ignored: brackets inside inline code, code blocks, math ($...$) and frontmatter, escaped brackets (\(), and ordered list markers like 1) / a) at the start of a line.

Works in the editor (Live Preview and Source mode). Reading view is not affected. Desktop and mobile.

Installation

From Community plugins (once approved): Settings → Community plugins → Browse → search "Rainbow Brackets".

Manually: download main.js, manifest.json and styles.css from the latest release into <your vault>/.obsidian/plugins/rainbow-brackets/, then enable the plugin in Settings → Community plugins.

With BRAT: add yndarra/obsidian-rainbow-brackets.

Customizing colors

Create a CSS snippet (Settings → Appearance → CSS snippets) and override the variables:

body.theme-dark {
	--rb-0: #ffb20d;  /* level 1 */
	--rb-1: #da70d6;  /* level 2 */
	--rb-2: #4fc1ff;  /* level 3 */
	--rb-3: #6fdc8c;  /* level 4 */
	--rb-bad: #ff4d4d;                       /* unmatched */
	--rb-active-bg: rgba(255, 255, 255, .18); /* pair at the cursor */
}
body.theme-light { /* same variables for the light theme */ }

Development

No build step — main.js is the plugin itself. Tests: node --test.

По-русски

Плагин подсвечивает скобки в обычном тексте заметок: раскрашивает их по уровню вложенности, выделяет пару к скобке у курсора и показывает красным скобки без пары. Скобки в коде, формулах и маркеры списков вида 1) не трогает. Цвета можно поменять через CSS-сниппет (см. выше).
