Stylesheet
  diagnostics : Array[@marianoguerra/shrubbery-css/error.Diagnostic
Diagnostic]
}

A lowering: the tree, and everything noticed on the way.

pub struct LoweredBlock {
  items : Array[@marianoguerra/css/ast.BlockItem

lower

source

fn lower(root : @marianoguerra/shrubbery/ast.Node

ShrubCssError

Lower a parsed shrubbery tree.

lower_block

source

fn lower_block(root : @marianoguerra/shrubbery/ast.Node
Node, strict? : Bool) -> LoweredBlock raise @marianoguerra/shrubbery-css/error.ShrubCssError
ShrubCssError

Lower a parsed shrubbery tree as the BODY of a rule.

lower starts at the top of a file, where CSS has no declarations at all -- so a consumer holding a SCOPED fragment cannot use it. Everything that goes inside one [data-cid="3"] { ... } is made of exactly the declarations that are refused up there, and correctly refused: the context is the first level of the rule-versus-declaration cascade, and at the top of a file the answer really is "rule".

This is the same lowering in Nested, the context that admits both. A declaration is a declaration, a nested rule is a nested rule, and a top-level-only at-rule is refused the way it would be inside any other rule body.

lower_block_source

source

fn lower_block_source(src : String, strict? : Bool) -> LoweredBlock raise @marianoguerra/shrubbery-css/error.ShrubCssError
ShrubCssError

Parse a scoped shrubbery-CSS fragment and lower it as a rule body.

lower_source

source

fn lower_source(src : String, strict? : Bool) -> Lowered raise @marianoguerra/shrubbery-css/error.ShrubCssError
ShrubCssError

Parse shrubbery source and lower it in one step.

Shrubbery's own diagnostics come first and are converted, so a caller sees one list rather than having to consult two. A source that does not parse lowers to an empty stylesheet: there is no tree to lower, and inventing one would put the bridge's guesses where the notation's answer should be.
