Programmer's Notepad

Programmer's Notepad (PN1) is an open-source text 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.

Both PN1 and PN2 feature syntax highlighting for many programming languages through plugins called "schemes" that can be modified to support more languages. PN1 included syntax highlighting for: C++, CSS, HTML, INI, Java,JavaScript, AutoLISP, Pascal, Perl, SQL, Visual Basic and XML.

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.

A significant feature added to PN2 is code folding.

A feature that has been often requested, but is not currently included, is a spell checker. PN1 has a built-inhex editor that has yet to appear in PN2.
