MetaFlow

An Obsidian plugin that automatically applies metadata rules: when a new markdown file is created inside a watched folder, MetaFlow writes the rule's properties into its frontmatter.

Use cases

• Tag files synced from external tools (e.g. calendar events synced by another plugin) so Dataview/Bases can query them
• Auto-tag incoming notes per folder (food, meeting, ...)
• Inject standard properties like type or source without touching templates

Usage

1. Open Settings → MetaFlow
2. Click + 新增规则 and pick a folder to watch
3. Add properties (key/value pairs); a value containing commas becomes a list, e.g. calendar, sync → [calendar, sync]
4. Every new .md file created inside that folder gets the properties written to its frontmatter

Rules apply to newly created files only — files that already exist are not rewritten.

Development

No build step required — main.js is plain JavaScript and can be edited directly.
