# LexGen.py - implemented 2002 by Neil Hodgson neilh@scintilla.org
# Released to the public domain.

# Regenerate the Scintilla and SciTE source files that list
# all the lexers and all the properties files.
# Should be run whenever a new lexer is added or removed.
# Requires Python 2.4 or later
# Most files are regenerated in place with templates stored in comments.
# The VS .NET project file is generated into a different file as the
# VS .NET environment will not retain comments when modifying the file.
# The files are copied to a string apart from sections between a
# ++Autogenerated comment and a --Autogenerated comment which is
# generated by the CopyWithInsertion function. After the whole
# string is instantiated, it is compared with the target file and
# if different the file is rewritten.
# Does not regenerate the Visual C++ 6 project files but does the VS .NET
# project file.

    # Mac OS <=9 (a.k.a. "Mac Classic")
    NATIVE = LF

# Automatically generated sections contain start and end comments,
# a definition line and the results.
# The results are replaced by regenerating based on the definition line.
# The definition line is a comment prefix followed by "**".
# If there is a digit after the ** then this indicates which list to use
# and the digit and next character are not part of the definition
# Backslash is used as an escape within the definition line.
# The part between \( and \) is repeated for each item in the list.
# \* is replaced by each list item. \t, and \n are tab and newline.
