- name: variants
  display: Variants
  category: math
  functions: ["serif", "sans", "frak", "mono", "bb", "cal"]
  description: |
    Alternate typefaces within formulas.

    These functions are distinct from the [`text`]($text) function because math
    fonts contain multiple variants of each letter.

- name: styles
  display: Styles
  category: math
  functions: ["upright", "italic", "bold"]
  description: |
    Alternate letterforms within formulas.

    These functions are distinct from the [`text`]($text) function because math
    fonts contain multiple variants of each letter.

- name: sizes
  display: Sizes
  category: math
  functions: ["display", "inline", "script", "sscript"]
  description: |
    Forced size styles for expressions within formulas.

    These functions allow manual configuration of the size of equation elements
    to make them look as in a display/inline equation or as if used in a root or
    sub/superscripts.

- name: underover
  display: Under/Over
  category: math
  functions: [
    "underline",
    "overline",
    "underbrace",
    "overbrace",
    "underbracket",
    "overbracket",
  ]
  description: |
    Delimiters above or below parts of an equation.

    The braces and brackets further allow you to add an optional annotation
    below or above themselves.

- name: roots
  display: Roots
  category: math
  functions: ["root", "sqrt"]
  description: |
    Square and non-square roots.

    # Example
    ```example
    $ sqrt(3 - 2 sqrt(2)) = sqrt(2) - 1 $
    $ root(3, x) $
    ```

- name: attach
  display: Attach
  category: math
  functions: ["attach", "scripts", "limits"]
  description: |
    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
    ```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.

- name: lr
  display: Left/Right
  category: math
  functions: ["lr", "abs", "norm", "floor", "ceil", "round"]
  description: |
    Delimiter matching.

    The `lr` function allows you to match two delimiters and scale them with the
    content they contain. While this also happens automatically for delimiters
    that match syntactically, `lr` allows you to match two arbitrary delimiters
    and control their size exactly. Apart from the `lr` function, Typst provides
    a few more functions that create delimiter pairings for absolute, ceiled,
    and floored values as well as norms.

    # Example
    ```example
    $ [a, b/2] $
    $ lr(]sum_(x=1)^n] x, size: #50%) $
    $ abs((x + y) / 2) $
    ```

- name: calc
  display: Calculation
  category: foundations
  path: ["calc"]
  description: |
    Calculations and processing of numeric values.

    These functions are part of the `calc` module and not imported by default.
    In addition to the functions listed below, the `calc` module also defines
    the constants `pi`, `tau`, `e`, `inf`, and `nan`.
