# 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 2.1 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.
