# ScintillaData.py - implemented 2013 by Neil Hodgson neilh@scintilla.org
# Released to the public domain.
# Common code used by Scintilla and SciTE for source file regeneration.
# The ScintillaData object exposes information about Scintilla as properties:
# Version properties
# version
# versionDotted
# versionCommad
#
# Date last modified
# dateModified
# yearModified
# mdyModified
# dmyModified
# myModified
#
# Information about lexers and properties defined in lexers
# lexFiles
# sorted list of lexer files
# lexerModules
# sorted list of module names
# lexerProperties
# sorted list of lexer properties
# propertyDocuments
# dictionary of property documentation { name: document string }
# This file can be run to see the data it provides.
# Requires Python 2.5 or later
