This is a KomodoEdit extension for syntax-highlighting Objective-C++ files. To install the extension, open "objectivecpp-1.0.0-ko.xpi" with Komodo Edit. Alternatively, you can rebuild the .xpi file from these sources by cd'ing to the top-level directory (the one containing this README) and running $MOZPYTHON_PATH/mozpython $KOEXT_PATH/koext build On OS X, mozpython lives in /Applications/Komodo\ Edit.app/Contents/MacOS/mozpython and koext lives in /Applications/Komodo\ Edit.app/Contents/SharedSupport/sdk/bin/koext Once you install this extension, KomodoEdit will treat files as Objective-C++ if they have an .mm extension. (Eventually I will figure out how to add the .M, .hh, and .h extensions.) The keyword list includes those keywords that were newly added in C++11, such as "decltype" and "thread_local".
