  • Enabled DISABLE_D2D by default
  • Stopped awkward centering of the selected item in autocompletion lists
  • Added SC_MARK_BACKFORE
  • Minor autocompletion improvements
  • Changed indent/dedent to always include the cursor line
  • Fixed SCI_SETSELECTION to notify the container when clearing multiple selections
  • Fixed pixel alignment when drawing RGBA images
  • Fixed Scintilla.iface comments for style offset setters that incorrectly said "Get" instead of "Set"

Signed versions of the x86 and x64 DLL files can be downloaded from the issrc repository, renamed as isscint(-x64).dll

README for building of Scintilla, Lexilla, and SciTE

Scintilla and Lexilla can be built by themselves. To build SciTE, Scintilla and Lexilla should first be built.

See lexilla/README for information on building Lexilla.

*** GTK+/Linux version ***

You must first have GTK+ 2.24 or later and GCC (7.1 or better) installed. Clang may be used by adding CLANG=1 to the make command line. Other C++ compilers may work but may require tweaking the make file. Either GTK+ 2.x or 3.x may be used with 2.x the default and 3.x chosen with the make argument GTK3=1.

To build Scintilla, use the makefile located in the scintilla/gtk directory cd scintilla/gtk make cd ../..

To build and install SciTE, use the makefile located in the scite/gtk directory cd scite/gtk make sudo make install

This installs SciTE into prefix/bin.Thevalueofprefix/bin. The value of prefix is determined from the location of Gnome if it is installed. This is usually /usr if installed with Linux or /usr/local if built from source. If Gnome is not installed /usr/bin is used as the prefix. The prefix can be overridden on the command line like "make prefix=/opt" but the same value should be used for both make and make install as this location is compiled into the executable. The global properties file is installed at $prefix/share/scite/SciTEGlobal.properties. The language specific properties files are also installed into this directory.

To remove SciTE sudo make uninstall

To clean the object files which may be needed to change $prefix make clean

The current make file supports static and dynamic linking between SciTE, Scintilla, and Lexilla.

*** Windows version ***

A C++ 17 compiler is required. Visual Studio 2019 is the development system used for most development although Mingw-w64 9.2 is also supported.

To build Scintilla, make in the scintilla/win32 directory cd scintilla\win32 GCC: mingw32-make Visual C++: nmake -f scintilla.mak cd ....

To build SciTE, use the makefiles located in the scite/win32 directory cd scite\win32 GCC: mingw32-make Visual C++: nmake -f scite.mak

An executable SciTE will now be in scite/bin.

*** GTK+/Windows version ***

Mingw-w64 is known to work. Other compilers will probably not work.

Only Scintilla will build with GTK+ on Windows. SciTE will not work.

Make builds both a static library version of Scintilla with lexers (scintilla.a) and a shared library without lexers (libscintilla.so or libscintilla.dll).

To build Scintilla, make in the scintilla/gtk directory cd scintilla\gtk mingw32-make

*** macOS Cocoa version ***

Xcode 9.2 or later may be used to build Scintilla on macOS.

There is no open source version of SciTE for macOS but there is a commercial version available through the App Store.

To build Scintilla, run xcodebuild in the scintilla/cocoa/ScintillaFramework or scintilla/cocoa/Scintilla directory

    cd cocoa/Scintilla

xcodebuild

*** Qt version ***

See the qt/README file to build Scintilla with Qt.
