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.
