Programmer's Notepad (PN1) is an open-sourcetext editor targeted at users who work with source code. It was released in 1998 by Echo Software (a trading name for Simon Steele). PN1's successor, Programmer's Notepad 2 (PN2), was released in 2002 and is now based on Scintilla. PN2 adds to Scintilla's features by supporting multi-line regular expressions for search and replace actions.
Other significant features common to both editor versions are "Scheme Tools" and "Text Clips." Scheme Tools allow the user to make highly customizable calls to other programs (such as a compiler) based on the scheme of the current file. Text Clips are code templates or values that can be inserted into the current document to speed up development time.
