Strings

This reference documents the Julia to Typst interface, a custom string corresponding to Typst source text, and its implementation of the String interface.

`Typstry`

Typstry.Strings.Mode — Type

Mode

An Enumerated type used to specify that the current Typst syntactical context is code, markup, or math.

Examples

julia> Mode
Enum Mode:
code = 0
markup = 1
math = 2

source

Typstry.Strings.Typst — Type

Typst{T}
Typst(::T)

A wrapper used to pass values to show(::IO, ::MIME"text/typst", ::Typst).

Examples

julia> Typst(1)
Typst{Int64}(1)

julia> Typst("a")
Typst{String}("a")

source

Typstry.Strings.TypstString — Type

TypstString <: AbstractString
TypstString(::Any; context...)

Format the value as a Typst formatted string.

Optional Julia settings and Typst parameters are passed to show(::IO, ::MIME"text/typst", ::Typst) in an IOContext. See also show_typst for a list of supported types.

Info

This type implements the String interface. However, the interface is undocumented, which may result in unexpected behavior.

Examples

julia> TypstString(1)
typst"$1$"

julia> TypstString(1 + 2im; mode = math)
typst"(1 + 2i)"

source

Typstry.Strings.TypstText — Type

TypstText{T}
TypstText(::Any)

A wrapper whose show_typst method uses print.

Info

This may be used to insert control characters into a TypstString. Unescaped control characters in TypstStrings may break formatting in some environments, such as the REPL.

Examples

julia> TypstText(1)
TypstText{Int64}(1)

julia> TypstText("a")
TypstText{String}("a")

source

Typstry.Strings.@typst_str — Macro

@typst_str("s")
typst"s"

Construct a TypstString.

Control characters are escaped, except double quotation marks and backslashes in the same manner as @raw_str. Values may be interpolated by calling the TypstString constructor, except using a backslash instead of the type name. Interpolation syntax may be escaped in the same manner as quotation marks.

Tip

Print directly to an IO using show(::IO, ::MIME"text/typst", ::Typst).

See also the performance tip to Avoid string interpolation for I/O.

Examples

julia> x = 1;

julia> typst"$ \(x; mode = math) / \(x + 1; mode = math) $"
typst"$ 1 / 2 $"

julia> typst"\(x//2)"
typst"$1 / 2$"

julia> typst"\(x // 2; mode = math)"
typst"(1 / 2)"

julia> typst"\\(x)"
typst"\\(x)"

source

Typstry.Strings.code — Constant

code

A Typst syntactical Mode prefixed by the number sign.

Examples

julia> code
code::Mode = 0

source

Typstry.Strings.markup — Constant

markup

A Typst syntactical Mode at the top-level of source text and enclosed within square brackets.

julia> markup
markup::Mode = 1

source

Typstry.Strings.math — Constant

math

A Typst syntactical Mode enclosed within dollar signs.

julia> math
math::Mode = 2

source

Typstry.Strings.context — Function

context(x)

Provide formatting data for show(::IO, ::MIME"text/typst", ::Typst).

Implement this function for a custom type to specify its custom settings and parameters. Passing a value wrapped in Typst will merge! its custom context with defaults, such that the defaults may be overwritten. To be compatible with merging contexts and constructing an IOContext, methods must return an AbstractDict{Symbol}.

Setting	Default	Type	Description
`:backticks`	`3`	`Int`	The number of backticks to enclose raw text markup, which may be increased to disambiguiate nested raw text.
`:block`	`false`	`Bool`	When `:mode => math`, specifies whether the enclosing dollar signs are padded with a space to render the element inline or its own block.
`:depth`	`0`	`Int`	The current level of nesting within container types to specify the degree of indentation.
`:mode`	`markup`	`Mode`	The current Typst syntactical context where `code` follows the number sign, `markup` is at the top-level and enclosed in square brackets, and `math` is enclosed in dollar signs.
`:parenthesize`	`true`	`Bool`	Whether to enclose some mathematical elements in parentheses to specify their operator precedence and avoid ambiguity.
`:tab_size`	`2`	`Int`	The number of spaces used by some elements with multi-line Typst formatting, which is repeated for each level of `depth`

source

Typstry.Strings.show_typst — Method

show_typst(io, x)

Print in Typst format with Julia settings and Typst parameters provided by an IOContext.

Implement this function for a custom type to specify its Typst formatting. A setting is a value used in Julia, whose type varies across settings. A parameter is passed directly to a Typst function and must be a TypstString with the same name as in Typst, except that dashes are replaced with underscores. Settings each have a default value, whereas the default values of parameters are handled by Typst functions. Some settings, such as block, correspond with a parameter but may also be used in Julia.

For additional information on settings and parameters, see also context and the Typst Documentation, respectively.

Info

Some types, particularly containers, may call show(::IO, ::MIME"text/typst", ::Typst) to format a value, which may use additional settings and parameters.
