Attach
Subscript, superscripts, and limits.
Attachments can be displayed either as sub/superscripts, or limits. Typst automatically decides which is more suitable depending on the base, but you can also control this manually with the scripts and limits functions.
Example
$ sum_(i=0)^n a_i = 2^(1+i) $
Syntax
This function also has dedicated syntax for attachments after the base: Use the underscore (_) to indicate a subscript i.e. bottom attachment and the hat (^) to indicate a superscript i.e. top attachment.
Functions
attachElement
A base with optional attachments.
$ attach(
Pi, t: alpha, b: beta,
tl: 1, tr: 2+3, bl: 4+5, br: 6,
) $
base
The base to which things are attached.
t
The top attachment, smartly positioned at top-right or above the base.
You can wrap the base in limits() or scripts() to override the smart positioning.
Default: none
b
The bottom attachment, smartly positioned at the bottom-right or below the base.
You can wrap the base in limits() or scripts() to override the smart positioning.
Default: none
tl
The top-left attachment (before the base).
Default: none
bl
The bottom-left attachment (before base).
Default: none
tr
The top-right attachment (after the base).
Default: none
br
The bottom-right attachment (after the base).
Default: none
scriptsElement
Forces a base to display attachments as scripts.
$ scripts(sum)_1^2 != sum_1^2 $
body
The base to attach the scripts to.
limitsElement
Forces a base to display attachments as limits.
$ limits(A)_1^2 != A_1^2 $
body
The base to attach the limits to.
inline
Whether to also force limits in inline equations.
When applying limits globally (e.g., through a show rule), it is typically a good idea to disable this.
Default: true
