Questions tagged [cc-mode]

CC Mode is an Emacs and XEmacs mode for editing C and other languages with similar syntax; currently C++, Objective-C, Java, CORBA's IDL, Pike and AWK. It's a standard package in both Emacs and XEmacs.

CC Mode supports the editing of K&R and ANSI C, C++, Objective-C, Java, CORBA's Interface Definition Language, Pike and AWK files.

Note that the name of this package is CC Mode, but there is no top level cc-mode entry point. All of the variables, commands, and functions in CC Mode are prefixed with c-thing, and c-mode: c++-mode, objc-mode, java-mode, idl-mode, pike-mode, and awk-mode entry points are provided. This package is intended to be a replacement for c-mode.el, c++-mode.el and awk-mode.el.

Controlling the indent/offset for CMake in emacs
