Detailed Description

A simple lexer matches texts with simple regular expressions.

Constructor & Destructor Documentation

◆ GrammarTextLexer()

edbee::GrammarTextLexer::GrammarTextLexer ( TextDocumentScopes * scopes )

Constructs the grammar textlexer.

Parameters

scopes a reference to the scopes model

◆ ~GrammarTextLexer()

edbee::GrammarTextLexer::~GrammarTextLexer ( )

virtual

The destructor.

Member Function Documentation

◆ lexLines()

void edbee::GrammarTextLexer::lexLines	(	int	lineStart,
		int	lineCount )

virtual

This method lexes a range of line.

Returns: the last indexed offset

◆ lexRange()

void edbee::GrammarTextLexer::lexRange	(	int	beginOffset,
		int	endOffset )

virtual

This method is called when the given range needs to be lexed.

WARNING, this method must be VERY optimized and should 'remember' the lexing states between calls. To invalidate the scopes/lexing state the textReplaced method can be used
