Revision history for typst-hs

0.6

• Recognize figure.caption function (#52).

• Allow defined identifiers to override math defaults (#51). Previously we evaluated all math in a special environment that shadowed any user-defined functions with the same-named functions from the math or sym modules. This change gives user-defined identifiers priority over the math defaults, allowing things like bb to be overridden.

• Typst.Types: EvalState now has two new fields, evalMathIdentifiers and evalStandardIdentifiers. evalIdentifiers is now just for user-defined identifiers. [API change]

• Don’t implicitly load sys module for math.

0.5.0.5

• Allow numbers like 1. in math mode (#50).

0.5.0.4

• Add built-in identifiers for standard types (#21): array, bool, content, int, float, regex, length, alignment, color, symbol, string.

• Adjust emphasis parser for CJK characters (#49). Typst documentation says that * strong emphasis “only works at word boundaries.” However, in typst/typst#2648 this was changed for CJK.

0.5.0.3

• Support grid.(cell,header,footer,hline,vline) (#44).

• Support table.(cell,vline,hline,header,footer) (#44).

• Allow space after equation in code (#43).

• Treat unicode whitespace characters as whitespace (#43).

• Allow raw (backticked) content as code expression (#43).

• Allow colon in label (#43).

• Allow line comments at end of file (#43).

• Depend on typst-symbols 0.1.6.

• Add Haddock docs to parts of the public API (Eli Adelhult, Leopold Wigratt).

• Avoid backtracking in pDictExpr (Jonathan Widén).

• Allow colon in dict literal (Jonathan Widén) (#43, #45).

0.5.0.2

• Fix parsing of field access in math (#41). $plus.circle_2$ should give you a subscript 2 on the symbol plus.circle. Underscores are not allowed in field access in math.

• Support toml-parser-2.0.0.0 (Eric Mertens).

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.
