Module implementing a base class for custom lexers.

from PyQt4.Qsci import QsciLexer

from Lexer import Lexer

class LexerContainer(QsciLexer, Lexer):
    Subclass as a base for the implementation of custom lexers.
    def __init__(self, parent = None):
        @param parent parent widget of this lexer
        QsciLexer.__init__(self, parent)
        self.editor = parent
    def language(self):
        Public method returning the language of the lexer.
        @return language of the lexer (string)
        return "Container"
    def lexer(self):
        Public method returning the type of the lexer.
        @return type of the lexer (string)
        if hasattr(self, 'lexerId'):
            return None
            return "container"
    def description(self, style):
        Public method returning the descriptions of the styles supported
        by the lexer.
        <b>Note</b>: This methods needs to be overridden by the lexer class.
        @param style style number (integer)
        @return description for the given style (string)
        return ""
    def styleBitsNeeded(self):
        Public method to get the number of style bits needed by the lexer.
        @return number of style bits needed (integer)
        return 5
    def styleText(self, start, end):
        Public method to perform the styling.
        @param start position of first character to be styled (integer)
        @param end position of last character to be styled (integer)
        self.editor.startStyling(start, 0x1f)
        self.editor.setStyling(end - start + 1, 0)
