title: 0.8.0
description: Changes in Typst 0.8.0

Version 0.8.0 (September 13, 2023)

Scripting

• Plugins (thanks to @astrale-sharp and @arnaudgolfouse)
  • Typst can now load plugins that are compiled to WebAssembly
  • Anything that can be compiled to WebAssembly can thus be loaded as a plugin
  • These plugins are fully encapsulated (no access to file system or network)
  • Plugins can be shipped as part of packages
  • Plugins work just the same in the web app
• Types are now first-class values (Breaking change)
  • A [type] is now itself a value
  • Some types can be called like functions (those that have a constructor), e.g. [int] and [str]
  • Type checks are now of the form {type(10) == int} instead of the old {type(10) == "integer"}. Compatibility with the old way will remain for a while to give package authors time to upgrade, but it will be removed at some point.
  • Methods are now syntax sugar for calling a function scoped to a type, meaning that {"hello".len()} is equivalent to {str.len("hello")}
• Added support for import renaming with as
• Added a [duration] type
• Added support for CBOR encoding and decoding
• Added encoding and decoding functions from and to bytes for data formats: json.decode, json.encode, and similar functions for other formats
• Added array.intersperse function
• Added str.rev function
• Added calc.tau constant
• Made [bytes] joinable and addable
• Made array.zip function variadic
• Fixed bug with [eval] when the mode was set to {"math"}
• Fixed bug with ends-with function on strings
• Fixed bug with destructuring in combination with break, continue, and return
• Fixed argument types of hyperbolic functions, they don't allow angles anymore (Breaking change)
• Renamed some color methods: rgba becomes to-rgba, cmyk becomes to-cmyk, and luma becomes to-luma (Breaking change)

Export

• Added SVG export (thanks to @Enter-tainer)
• Fixed bugs with PDF font embedding
• Added support for page labels that reflect the page numbering style in the PDF

Text and Layout

• Added [highlight] function for highlighting text with a background color
• Added polygon.regular function for drawing a regular polygon
• Added support for tabs in [raw] elements alongside tab-width parameter
• The layout engine now tries to prevent "runts" (final lines consisting of just a single word)
• Added Finnish translations
• Added hyphenation support for Polish
• Improved handling of consecutive smart quotes of different kinds
• Fixed vertical alignments for number-align argument on page function (Breaking change)
• Fixed weak pagebreaks after counter updates
• Fixed missing text in SVG when the text font is set to "New Computer Modern"
• Fixed translations for Chinese
• Fixed crash for empty text in show rule
• Fixed leading spaces when there's a linebreak after a number and a comma
• Fixed placement of floating elements in columns and other containers
• Fixed sizing of block containing just a single box

Math

• Added support for augmented matrices
• Removed support for automatic matching of fences like | and || as there were too many false positives. You can use functions like abs or norm or an explicit lr call instead. (Breaking change)
• Fixed spacing after number with decimal point in math
• Fixed bug with primes in subscript
• Fixed weak spacing
• Fixed crash when text within math contains a newline

Tooling and Diagnostics

• Added hints when trying to call a function stored in a dictionary without extra parentheses
• Fixed hint when referencing an equation without numbering
• Added more details to some diagnostics (e.g. when SVG decoding fails)

Command line interface

• Added typst update command for self-updating the CLI (thanks to @jimvdl)
• Added download progress indicator for packages and updates
• Added --format argument to explicitly specify the output format
• The CLI now respects proxy configuration through environment variables and has a new --cert option for setting a custom CA certificate
• Fixed crash when field wasn't present and --one is passed to typst query

Miscellaneous Improvements

• Added page setup guide
• Added figure.caption function that can be used for simpler figure customization (Breaking change because it.caption now renders the full caption with supplement in figure show rules and manual outlines)
• Moved caption-pos argument to figure.caption function and renamed it to position (Breaking change)
• Added separator argument to figure.caption function
• Added support for combination of and/or and before/after selectors
• Packages can now specify a minimum compiler version they require to work
• Fixed parser bug where method calls could be moved onto their own line for [#let] expressions in markup (Breaking change)
• Fixed bugs in sentence and title case conversion for bibliographies
• Fixed supplements for alphanumeric and author-title bibliography styles
• Fixed off-by-one error in APA bibliography style

Development

• Made Span and FileId more type-safe so that all error conditions must be handled by World implementors
