- Refactors the tokenizer to be lazy: It does not emit pre-parsed function tokens, but instead allows it's mode to be changed. The modes are tracked on a stack to allow nested compute/typesetting (pop/push).
- Introduces delimited groups into the parser, which make it easy to parse delimited expressions without handling the delimiters in the parsing code for the group's content. A group is started with `start_group`. When reaching the group's end (matching delimiter) the eat and peek methods will simply return `None` instead of the delimiter, stopping the content parser and bubbling up the call stack until `end_group` is called to clear up the situation.
- Problems -> Diagnostics
- Position -> Pos
- offset_spans -> Offset trait
- Size -> Length (and some more size types renamed)
- Paper into its own module
- scope::Parser -> parsing::CallParser
- Create `Decorations` alias
- Remove lots of double newlines
- Switch from f32 to f64
- Forced line breaks with backslash followed by whitespace
- (Multline) raw text in backticks
- Set font class fallbacks with [font.family] (e.g. [font.family: monospace=("CMU Typewriter Text")])
- More sophisticated procedure to find end of function, which accounts for comments, strings, raw text and nested functions (this is a mix of a feature and a bug fix)
- Dynamic models instead of SyntaxTrees
- No more ParseResult/LayoutResult
- Errors and Decorations which are propagated to parent contexts
- Models are finally clonable
