This plugin is a pretty basic keyword handler for my own personal needs to automate a task that I do manually to save me some time. If it is useful for you, feel free to go ahead and use it.

The plugin adds a command on load called Add Keywords to YAML. This command is an editor command. It does the following:

• Gets the text for the current editor
• Gets the current keywords value from the frontmatter if there is one
• Gets all markdown links in the current file from the cached metadata
• Gets the file and then the file metadata cache to check for the keyword key's value in the referenced file
• If the keyword has any spaces in it, it has double quotes used to escape the value
• If the keyword does not already exist in the list, it gets added
• Adds the keywords to the frontmatter if the value has changed

• Clone this repo.
• Make sure your NodeJS is at least v16 (node --version).
• npm i or yarn to install dependencies.
• npm run dev to start compilation in watch mode.

• Copy over main.js, styles.css, manifest.json to your vault VaultFolder/.obsidian/plugins/your-plugin-id/.
