Typst 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
