Scintilla

Scintilla is a free source code editing component. Scintilla 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.

The SinkWorld project investigates possible future directions for Scintilla to make it more flexible, robust, perform better and run on the .NET and Java virtual machines.

Development of Scintilla started as an effort to improve the text editor in PythonWin. After being frustrated by problems in the Richedit control used by PythonWin, it looked like the best way forward was to write a new edit control.

The biggest problem with Richedit and other similar controls is that they treat styling changes as important persistent changes to the document so they are saved into the undo stack and set the document's dirty flag. For source code, styling should not be persisted as it can be mechanically recreated.

Scintilla and SciTE are currently available for Intel Win32 and Linux compatible operating systems with GTK+.

What is new in this release:

• SciTE on Windows now runs Lua scripts directly on the main thread instead of starting them on a secondary thread and then moving back to the main thread.
• Highlight "else" as a keyword for TCL in the same way as other languages. Bug #1836954.
• Fix problems with setting fonts for autocompletion lists on Windows where font handles were copied and later deleted causing a system default font to be used.
• Fix font size used on Windows for Asian language input methods which sometimes led to IME not being visible. Bug #3436753.
• Fixed polygon drawing on Windows so fold symbols are visible again. Bug #3433558.
• Changed background drawing on GTK+ to allow for fractional character positioning as occurs on OS X as this avoids faint lines at lexeme boundaries.
• Ensure pixmaps allocated before painting as there was a crash when Scintilla drew without common initialisation calls. Bug #3432354.
• Fixed SciTE on Windows bug causing wrong caret position after indenting a selection. Bug #3433433.
• Fixed SciTE session saving to store buffer position matching buffer. Bug #3434372.
• Fixed leak of document objects in SciTE.
• Recognize URL characters '?' and '%' for Open Selected command in SciTE. Bug #3429409.

What is new in version 2.21:

• Asian Double Byte Character Set (DBCS) support improved. Case insensitive search works and other operations are much faster. Bug #2999125, Bug #2774616, Bug #2991942, Bug #3005688.
• Scintilla on GTK+ uses only non-deprecated APIs (for GTK+ 2.20) except for GdkFont and GdkFont use can be disabled with the preprocessor symbol DISABLE_GDK_FONT.
• IDocument interface used by lexers adds BufferPointer and GetLineIndentation methods.
• On Windows, clicking sets focus before processing the click or sending notifications.
• Bug on OS X (macosx platform) fixed where drag/drop overwrote clipboard. Bug #3039732.
• GTK+ drawing bug when the view was horizontally scrolled more than 32000 pixels fixed.
• SciTE bug fixed with invoking Complete Symbol from output pane. Bug #3050957.
• Bug fixed where it was not possible to disable folding. Bug #3040649.
• Bug fixed with pressing Enter on a folded fold header line not opening the fold. Bug #3043419.
• SciTE 'Match case' option in find and replace user interfaces changed to 'Case sensitive' to allow use of 'v' rather than 'c' as the mnemonic.
• SciTE displays stack trace for Lua when error occurs.. Bug #3051397.
• SciTE on Windows fixes bug where double clicking on error message left focus in output pane. Bug #1264835.
• SciTE on Windows uses SetDllDirectory to avoid a security problem.
• C++ lexer crash fixed with preprocessor expression that looked like division by 0. Bug #3056825.
• Haskell lexer improved. Feature #3039490.
• HTML lexing fixed around Django {% %} tags. Bug #3034853.
• HTML JavaScript lexing fixed when line end escaped. Bug #3038381.
• HTML lexer stores line state produced by a line on that line rather than on the next line.
• Markdown lexer fixes infinite loop. Bug #3045386.
• MySQL folding bugs with END statements fixed. Bug #3031742.
• PowerShell lexer allows '_' as a word character. Feature #3042228.
• SciTE on GTK+ abandons processing of subsequent commands if a command.go.needs command fails.
• When SciTE is closed, all buffers now receive an OnClose call. Bug #3033857.

What is new in version 2.12:

• Improves drawing speed and fixes bugs.

What is new in version 2.03:

• Version 2.03 fixes some problems with rectangular selection.

What is new in version 2.01:

• Scintilla

What is new in version 1.77:

• Direct temporary access to Scintilla's text buffer to allow simple efficient interfacing to libraries like regular expression libraries.
• Scintilla on Windows can interpret keys as Unicode even when a narrow character window with SCI_SETKEYSUNICODE.
• Notification sent when autocompletion cancelled.
• Lexers added for MySQL and gettext .po files.
