Static Methods

delimiterFromName(String raw) → String

extractColorName(LatexNode node) → String

Extracts a color name string from a node.

extractCommandName(LatexNode node) → String

Extracts a command name from a node (removes the backslash).

extractDelimiter(LatexNode node) → String

Extracts a delimiter character from a parsed argument. Both literal delimiters and command forms such as \langle/\rVert are accepted.

extractText(List<LatexNode> nodes) → String

Extracts plain text from a list of nodes.

parseDimension(LatexParserContext ctx, LatexTokenStream stream) → String

Parses a TeX dimension either in braces ({1.2em}) or in the usual unbraced form (1.2em). Leading whitespace is ignored.

parseScriptContent(LatexParserContext ctx, LatexTokenStream stream) → LatexNode

Parses sub/superscript content (single factor or braced group).

parseScriptGroup(LatexParserContext ctx, LatexTokenStream stream) → (LatexNode?, LatexNode?)

Parses a script group {_a^b} and returns (sub, sup).

parseScriptsAndLimits(LatexParserContext ctx, LatexTokenStream stream) → (LatexNode?, LatexNode?, LimitsMode)

Parses following \limits/\nolimits and sub/superscripts. Returns a tuple of (subscript, superscript, limitsMode).

parseTensorIndicesGroup(LatexParserContext ctx, LatexTokenStream stream) → List<(bool, LatexNode)>

Parses a tensor indices list from a braced token stream.

parseUntil(LatexParserContext ctx, LatexTokenStream stream, bool condition(LatexToken)) → List<LatexNode>

Parses a list of nodes until the condition is met.
