#plug

Warning

Deprecated Directives are now deprecated and will likely soon be removed, use Live Templates and Live Queries instead.

The directive plug is a built-in plug implementing various so-called “directive” that all take the form of <!-- #directiveName ... --> and close with <!-- /directiveName -->. Currently the following directives are supported:

• #query to perform queries: Live Queries
• #include to inline the content of another page verbatim: @include
• #use to use the content of another as a handlebars template: @use
• #eval to evaluate an arbitrary JavaScript expression and inline the result: @eval

Include

$include The #include directive can be used to embed another page into your existing one. The syntax is as follows:

<!-- #include [[page reference]] -->

<!-- /include -->

Whenever the directives are updated, the body of the directive will be replaced with the latest version of the reference page.

Use

$use The #use directive can be used to use a referenced page as a handlebars template. Optionally, a JSON object can be passed as argument to the template:

<!-- #use [[template/plug]] {"name": "🔌 Directive", "repo": "https://google.com", "author": "Pete"} -->

<!-- /use -->

which renders as follows:

• 🔌 Directive by Pete (repo)

• #test This is a test task

Note that a string is also a valid JSON value:

So, for instance, a template can take a tag name as an argument:

<!-- #use [[template/tagged-tasks]] "test" -->
* [ ] [[🔌 Directive@1537]] This is a test task  #test
<!-- /use -->
