BlockParser
@Js
abstract class BlockParser : Obj
A block parser is able to parse a specific block node.
Return true if the this block may contain the child block
Default implementation does nothing with the source line
Add a source span of the currently parsed block
Return true if the block can have lazy continuation lines
Do any processing when the block is closed
Return true if the block that is parsed is a container (i.e
Get the parsed block
Attempt to continue parsing the block from the given state
Return the definitions parsed by this parser
Callback to parse inline content
virtual Void addLine(SourceLine line)
Default implementation does nothing with the source line
virtual Void addSourceSpan(SourceSpan sourceSpan)
Add a source span of the currently parsed block. The default implementation adds it to the block. Unless you have some complicated parsing where you need to check source positions, you don't need to override this.
abstract Block block()
Get the parsed block
virtual Bool canContain(Block childBlock)
Return true if the this block may contain the child block; false otherwise (default)
virtual Bool canHaveLazyContinuationLines()
Return true if the block can have lazy continuation lines.
Lazy continuation lines are lines that were rejected by this tryContinue but didn't match any other block parser either.
If true is returned here, those lines will get added via addLine. For false (default), the block is closed instead.
virtual Void closeBlock()
Do any processing when the block is closed
virtual DefinitionMap[] definitions()
Return the definitions parsed by this parser. The definitions returned here can later be accessed during inline parsing.
virtual Bool isContainer()
Return true if the block that is parsed is a container (i.e. contains other blocks), or false (default) if it's a leaf.
virtual Void parseInlines(InlineParser inlineParser)
Callback to parse inline content
abstract BlockContinue? tryContinue(ParserState state)
Attempt to continue parsing the block from the given state
