I have written my first script to contribute to the Programmer's Notepad community. It converts all identifiers in a file that are in under_score format into PascalCase format.
This was a great project to help me learn more about Programmer's Notepad and scripting the editor and the Scintilla interface with Python. I used the TabsToSpaces script as a starting point, and used the API listing script and the Scintilla documentation to help figure out functions and parameters.
I look forward to writing more scripts and integrating PNotepad more into my daily work. Thank you Simon for putting together such a great little editor!
