A library for parsing and evaluating typst syntax.
Typst (https://typst.app) is a document layout and
formatting language. This library targets typst 0.7
and currently offers only partial support.
Changes
Revision history for typst-hs
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.
