Changelog for typst-0.5.0.1

Revision history for typst-hs

0.5.0.1

Set evalPackageRoot to working dir to start, even if the file to be converted is somewhere else. This seems to be what the test suite expects.
Make file loading relative to package root if present (#39).
Parser: remove pBindExpr from pBaseExpr. It does not seem to be necessary, and it causes problems with things like $#x = $y$ (#34).
Fix assignment of module name in package imports (#30).
Don't allow container.at to insert new values (#26).
Handle dict.at(variable) = expression (#25).
Remove dependency on the unmaintained digits library (#24). We just copy the code for the function we need (with attribution): it is BSD3-licensed.

0.5

Support "as" keyword in imports (#21). [API change] In Typst.Syntax, the Imports type now contains fields for an optional "as" identifier.
Support version type (#21). [API change] Add VVersion constructor to Val, TVersion to ValType. Support the version constructor function and the at method (#21).
Parser: Ensure that set rule doesn't pick up if on next line (#23).
Parser: Allow multiline strings (#20).
Allow function applications in dictionary key construction (#19). [API change]: in Typst.Syntax, the Dict constructor for Expr now takes type [Spreadable (Expr, Expr)] instead of [Spreadable (Identifier, Expr)]. This is because the key identifiers sometimes are not known at parse time and must be computed in Evaluate.

0.4

evaluateTypst now returns a single Content instead of a sequence (breaking API change). The Content is a "document" element that wraps the other contents. (This is added automatically in typst: https://typst.app/docs/reference/model/document/#parameters-title.)
Improve math parser.
Add sys module and sys.version.
Math: add sech and csch operators, math.mid.
math.op is no longer limited to string argument.
Remove automatic matching for |..| in math (typst 0.8 breaking change).
Fix in so it works with a type.
repr label with angle brackets.
cite now just takes one positional element, a label instead of strings (typst 0.9 breaing change).
Add quote element.
Add first-class types. type() function now returns a ValType instead of a string. Allow ValTypes to == strings for compatibility, as in typst.
highlight element for text.
Allow array zip method to take any number of arguments.
Add calc.tau.
Add array intersperse method.
Add string rev method.
Fix search path for typst packages, from cache/typst/packages/preview/packagename-major.minor.patch to cache/typst/packages/preview/packagename-major/minor.patch (#18).
Add support of 'wide' spacing character.
Fix precedence for numerical attachments (#17). Typst makes a subtle distinction between $a_1(x)$ , in which the _ groups more tightly than the (..), and $`a_f(x)$, in which the (..)groups more tightly than the_. This patch implements the distinction. This fixes conversion of, e.g., $n(a)^(b)$`.
Use typst-symbols 0.1.5.

0.3.2.1

Fix resolution of symbols (#15). Symbols like dot, which only have variants, were not being properly resolved: we were getting the last matching variant rather than the first.
Avoid text's readFile in cli app (#13). Instead read as bytestring and force interpretation as UTF-8.
Fix some parser edge cases involving emphasis after ' (#12).

0.3.2.0

Add metadata element.
Add dedup method for vector.
Add math.class
Make MAttach on symbols include limits if symbol is relation. This is a 0.7 change: "Changed relations to show attachments as limits by default (e.g. in $a ->^x b$)."
Add Typst.MathClass.
Add im, id, tr text operators.
Parse math symbol shorthands as identifiers.
Use typst-symbols 0.1.4 so we get all of the defined shorthands.
Fix tests because of breaking symbol change ident -> equiv.
Depend on dev texmath.

0.3.1.0

Allow multiplying a ratio by a length.
Use symModule and mathModule directly when evaluating Equation instead of looking up sym and math.
Fix parsing of escapes in string literals. Symbols in general can't be escaped. There is just a small list of valid escapes.
Fix bugs in converting typst regexes to TDFA's format.
Allow Symbol to be regex replacement text.
Allow VString and VSymbol to be +'d.
Update for toml-parser-1.2.0.0 API changes (#9, Eric Mertens).
Derive the decoder for typst.toml (#7, Eric Mertens)
Implement typst's toml() function (#8, Eric Mertens).

0.3.0.0

We now target typst 0.6.
joinVals - fall back on repr when as a fallback in joining values.
Fix a spacing issue in parsing code inside equations (#6).
Fix #include. It wasn't including content!
Fix issue with math parsing of factorial (#5).
Handle "style" by evaluating it immediately, rather than passing it through as an element in content (#4).
Add outline.entry.
Allow identifiers to start with _.
Fix bug in parsing consecutive '#' expressions in math function (#2).
Fix bugs in makeLiteralRE.
Give namedArg an argument for a default value. This avoids spurious parse error messages.
Change return value of dictionary insert method to none.
Improve #panic output.
[API change]: Add Spreadable type in Typst.Syntax. Use this for Dict and Array values.
Handle package lookup, assuming packages are either local or cached.
API change: combine IO operations into Operations structure. evaluateTypst now takes a single Operations dictionary instead of separate loadBytes and currentUTCTime functions. And Operations now also includes functions to query environment variables and check directories. This will be needed for package lookup.
Depend on typst-symbols 0.1.2.
Make factorial take priority over fraction.

0.2.0.0

We now target typst 0.5.
Implement methods for datetime.
Implement base parameter on str.
Add datetime constructor.
Implement datetime.today.
Add VDateTime type.
Implement fields method on content.
Add display, inline, script, sscript to math module.
Add str.to-unicode, str.from-unicode.
Add calc.ln and calc.exp.
Remove deprecated calc.mod.
Depend on typst-symbols 0.1.1.

0.1.0.0

First version. Released on an unsuspecting world.
