Here is a list of all functions you can use in SilverBullet’s Expression Language:

Lists

count(list)

Count the number of elements in a list:

There are **{{count({page})}}** pages in this space.

at(list, index)

Returns the indexth element of list (starting from 0 of course).

Index 1 of our count to three is {{at([1, 2, 3], 1)}}

Templates

template(text, value)

Renders a template with an optional value:

{{template([[Library/Core/Query/Page]], {"name": "Some page"})}}

Date and time

today()

Today’s date in a YYYY-MM-dd format.

tomorrow()

yesterday()

Yesterday’s date in YYYY-MM-dd format.

niceDate(timestamp)

Convert a unix timestamp to a YYYY-MM-dd format.

time()

Current time.

String manipulation

replace(str, match, replacement)

Replace text in a string. match can either be a literal string or a regular expression: replace("hello", "ell", "all") would produce “hallo”, and replace("hello", /l/, "b") would produce “hebbo”.

This function supports an infinite number of replacements, so you can keep adding more, e.g. replace(str, match1, replacement1, match2, replacement2, match3, replacement3)

contains(str, substr)

Returns whether str contains substr as a substring.

json(obj)

Convert the argument to a JSON string (for debugging purposes).

The current page object: {{json(@page)}}

pageExists(name)

Checks if the page name exists:

This very page exists: {{pageExists(@page.name)}}

And this one: {{pageExists("non-existing")}}

readPage(name)

Reads in the content of the page name and returns it as a string.
