0 ;;; Clang Code-Completion minor mode, for use with C/Objective-C/C++.
5 ;; This minor mode uses Clang's command line interface for code
7 ;; and C++ source files. When enabled, Clang will provide
10 ;; space), Clang will provide the names of all structs visible from
12 ;; Clang will provide the names of all of the members of whatever
15 ;; completion based on Clang. It needs your help to make it better!
17 ;; To use the Clang code completion mode, first make sure that the
18 ;; "clang" variable below refers to the "clang" executable,
20 ;; clang-completion-mode.el somewhere in your Emacs load path. You can
33 ;; (load-library "clang-completion-mode")
35 ;; Finally, to try Clang-based code completion in a particular buffer,
36 ;; use M-x clang-completion-mode. When "Clang-CC" shows up in the mode
37 ;; line, Clang's code-completion is enabled.
39 ;; Clang's code completion is based on parsing the complete source
40 ;; file up to the point where the cursor is located. Therefore, Clang
43 ;; need to be placed into the clang-flags variable in a format
44 ;; acceptable to clang. This is a hack: patches are welcome to
45 ;; improve the interface between this Emacs mode and Clang!
