description: Changes in Typst 0.13.0

Version 0.13.0 (February 19, 2025)

Highlights

• There is now a distinction between proper paragraphs and just inline-level content. This is important for future work on accessibility and means that first line indent can now be enabled for all paragraphs instead of just consecutive ones.
• The [outline] has a better out-of-the-box look and is more customizable
• The new [curve] function (that supersedes the path function) provides a simpler and more flexible interface for creating Bézier curves
• The image function now supports raw pixel raster formats for generating images from within Typst
• Functions that accept file paths now also accept raw [bytes], for full flexibility
• WebAssembly plugins are more flexible and automatically run multi-threaded
• Fixed a long-standing bug where single-letter strings in math ([$"a"$]) would be displayed in italics
• You can now specify which charset should be covered by which font family
• The [pdf.embed] function lets you embed arbitrary files in the exported PDF
• HTML export is currently under active development. The feature is still very incomplete, but already available for experimentation behind a feature flag.

Model

• There is now a distinction between proper paragraphs and just inline-level content (Breaking change)
  • All text at the root of a document is wrapped in paragraphs. Meanwhile, text in a container (like a block) is only wrapped in a paragraph if the container holds any block-level content. If all of the content is inline-level, no paragraph is created.
  • In the laid-out document, it's not immediately visible whether text became part of a paragraph. However, it is still important for accessibility, HTML export, and for properties like first-line-indent.
  • Show rules on par now only affect proper paragraphs
  • The first-line-indent and hanging-indent properties also only affect proper paragraphs
  • Creating a {par[..]} with body content that is not fully inline-level will result in a warning
  • The default show rules of various built-in elements like lists, quotes, etc. were adjusted to ensure they produce/don't produce paragraphs as appropriate
  • Removed support for booleans and content in [outline.indent]
• The [outline] function was fully reworked to improve its out-of-the-box behavior (Breaking change)
  • Outline entries are now blocks and are thus affected by block spacing
  • The {auto} indentation mode now aligns numberings and titles outline-wide for a grid-like look
  • Automatic indentation now also indents entries without a numbering
  • Titles wrapping over multiple lines now have hanging indent
  • The page number won't appear alone on its own line anymore
  • The link now spans the full entry instead of just the title and page number
  • The default spacing between outline leader dots was increased
  • The fill parameter was moved from outline to outline.entry and can thus be configured through show-set rules
  • Removed body and page fields from outline entry
  • Added indented, prefix, inner, body, and page methods on outline entries to simplify writing of show rules
• Added configuration to [par.first-line-indent] for indenting all paragraphs instead of just consecutive ones
• Added form parameter to ref function. Setting the form to {"page"} will produce a page reference instead of a textual one.
• Added [document.description] field, which results in corresponding PDF and HTML metadata
• Added [enum.reversed] parameter
• Added support for Greek [numbering]
• When the [link] function wraps around a container like a [block], it will now generate only one link for the whole block instead of individual links for all the visible leaf elements. This significantly reduces PDF file sizes when combining link and [repeat].
• The [link] function will now only strip one prefix (like mailto: or tel:) instead of multiple
• The link function now suppresses hyphenation via a built-in show-set rule rather than through its default show rule
• Displaying the page counter without a specified numbering will now take the page numbering into account

Visualization

• Added new [curve] function that supersedes the [path] function and provides a simpler and more flexible interface. The path function is now deprecated.
• The image function now supports raw pixel raster formats. This can be used to generate images from within Typst without the need for encoding in an image exchange format.
• Added [image.scaling] parameter for configuring how an image is scaled by PNG export and PDF viewers (smooth or pixelated)
• Added [image.icc] parameter for providing or overriding the ICC profile of an image
• Renamed pattern to [tiling]. The name pattern remains as a deprecated alias.
• Added [gradient.center], [gradient.radius], [gradient.focal-center], and [gradient.focal-radius] methods
• Fixed interaction of clipping and outset on [box] and [block]
• Fixed panic with [path] of infinite length
• Fixed non-solid (e.g. tiling) text fills in clipped blocks
• Fixed a crash for images with a DPI value of zero
• Fixed floating-point error in [gradient.repeat]
• Auto-detection of image formats from a raw buffer now has support for SVGs

Scripting

• Functions that accept file paths now also accept raw [bytes]
  • [image], [cbor], [csv], [json], [toml], [xml], and [yaml] now support a path string or bytes and their .decode variants are deprecated
  • [plugin], [bibliography], [bibliography.style], [cite.style], [raw.theme], and [raw.syntaxes] now accept bytes in addition to path strings. These did not have .decode variants, so this adds new flexibility.
  • The path argument/field of [image] and [bibliography] was renamed to source and sources, respectively (Minor breaking change)
• Improved WebAssembly plugins
  • The plugin type is replaced by a plugin function that returns a [module] containing normal Typst functions. This module can be used with import syntax. (Breaking change)
  • Plugins now automatically run in multiple threads without any changes by plugin authors
  • A new [plugin.transition] API is introduced which allows plugins to run impure initialization in a way that doesn't break Typst's purity guarantees
• The variable name bound by a bare import (no renaming, no import list) is now determined statically and dynamic imports without {as} renaming (e.g. {import "ot" + "her.typ"}) are a hard error (Breaking change)
• Values of the [arguments] type can now be added with + and joined in curly-braced code blocks
• Functions in an element function's scope can now be called with method syntax, bringing elements and types closer (in anticipation of a future full unification of the two). Currently, this is only useful for [outline.entry] as no other element function defines methods.
• Added [calc.norm] function
• Added support for 32-bit floats in [float.from-bytes] and [float.to-bytes]
• The [decimal] constructor now also accepts decimal values
• Improved repr of symbols, [arguments], and types
• Duplicate [symbol] variants and modifiers are now a hard error (Breaking change)

Math

• Fixed a bug where single letter strings in math ([$"a"$]) would be displayed in italics
• Math function calls can now have hyphenated named arguments and support argument spreading
• Better looking accents thanks to support for the flac (Flattened Accent Forms) and dtls (Dotless Forms) OpenType features
• Added lcm text operator
• The bold function now works with ϝ and Ϝ
• The italic function now works with ħ
• Fixed a bug where the extent of a math equation was wrongly affected by internal metadata
• Fixed interaction of lr and [context] expressions
• Fixed weak spacing being unconditionally ignored in lr
• Fixed sub/superscripts sometimes being in the wrong position with lr
• Fixed multi-line annotations (e.g. overbrace) changing the math baseline
• Fixed merging of attachments when the base is a nested equation
• Fixed resolving of contextual (em-based) text sizes within math
• Fixed spacing around up tacks (⊥)

Bibliography

• Prose and author-only citations now use editor names if the author names are unavailable
• Some non-standard but widely used BibLaTeX editortypes like producer, writer, scriptwriter, and none (defined by widespread style biblatex-chicago to mean performers within music and video entries) are now recognized
• CSL styles can now render affixes around the bibliography
• For BibTeX entries with eprinttype = {pubmed}, the PubMed ID will now be correctly processed
• Whitespace handling for strings delimiting initialized names has been improved
• Uppercase spelling after apostrophes used as quotation marks is now possible
• Fixed bugs around the handling of CSL delimiting characters
• Fixed a problem with parsing multibyte characters in page ranges that could prevent Hayagriva from parsing some BibTeX page ranges
• Updated CSL APA style
• Updated CSL locales for Finnish, Swiss German, Austrian German, German, and Arabic

Text

• Added support for specifying which charset should be covered by which font family
• Added all parameter to smallcaps function that also enables small capitals on uppercase letters

• Fixed crash in RTL text handling
• Added support for [raw] syntax highlighting for a few new languages: CFML, NSIS, and WGSL
• New font metadata exception for New Computer Modern Sans Math
• Updated bundled New Computer Modern fonts to version 7.0.1

Layout

• Fixed various bugs with footnotes
  • Fixed footnotes getting lost when multiple footnotes were nested within another footnote
  • Fixed endless loops with empty and overlarge footnotes
  • Fixed crash with overlarge footnotes within a floating placement
• Fixed sizing of quadratic shapes ([square] and [circle])
• Fixed [block.sticky] not working properly at the top of a container
• Fixed crash due to consecutive weak spacing
• Fixed crash when a [block] or text have negative sizes
• Fixed unnecessary hyphenations occurring in rare scenarios due to a bad interaction between padding and paragraph optimization
• Fixed lone citations in [align] not becoming their own paragraph

Syntax

• Top-level closing square brackets that do not have a matching opening square bracket are now a hard error (Minor breaking change)
• Adding a space between the identifier and the parentheses in a set rule is not allowed anymore (Minor breaking change)
• Numbers with a unit cannot have a base prefix anymore, e.g. 0b100000pt is not allowed anymore. Previously, it was syntactically allowed but always resolved to a value of zero. (Minor breaking change)
• Using is as an identifier will now warn as it might become a keyword in the future
• Fixed minor whitespace handling bugs

PDF export

• Added [pdf.embed] function for embedding arbitrary files in the exported PDF

  • Added autocompletion for file paths
  • Smarter autocompletion of variables: Completing {rect(fill: |)} will now only show variables which contain a valid fill (either directly or nested, e.g. a dictionary containing a valid fill)
  • Different functions will now autocomplete with different brackets (round vs square) depending on which kind is more useful
  • Positional parameters which are already provided aren't autocompleted again anymore
