Description:

Scintilla is a free source code editing component. It comes with
complete source code and a license that permits use in any free
project or commercial product. As well as features found in standard
text editing components, Scintilla includes features especially useful
when editing and debugging source code. These include support for syntax
styling, error indicators, code completion and call tips. The selection
margin can contain markers like those used in debuggers to indicate
breakpoints and the current line. Styling choices are more open than with
many editors, allowing the use of proportional fonts, bold and italics,
multiple foreground and background colours and multiple fonts.
