RainLexer adds syntax highlighting support for Rainmeter .ini configuration files to Notepad++. To download RainLexer, follow the installation instructions.

To build RainLexer, you will need WinDDK 7.1. After you have it installed, make sure that the WinDDK71Dir entry in Config.props has the correct path. You can then build RainLexer by opening RainLexer.sln. Alternatively, you can run Build\Build.bat to build RainLexer and the installer.
