Starter Kit C++

This is part of the Emacs Starter Kit.

Starter Kit C++

Set C++ mode for *.h and *.ipp files (instead of plain-old C mode)

(setq auto-mode-alist (cons '("\\.h$"   . c++-mode) auto-mode-alist))
(setq auto-mode-alist (cons '("\\.ipp$" . c++-mode) auto-mode-alist))

Running starter-kit-coding-hook

(add-hook 'c-mode-common-hook 'run-starter-kit-coding-hook)

Un/fold function/namespace definitions

(add-hook 'c-mode-common-hook
          (lambda ()
            ;; hungry delete
            ;;(c-toggle-hungry-state t)
            (whitespace-mode t)))

Compilation

Scroll down compilation messages

(setq compilation-scroll-output t)

Send notification when compilation is done

(defun compile-notify (buffer message)
  (sk-popup "Emacs compilation" message))
(setq compilation-finish-function 'compile-notify)

Bury compilation buffer

If compilation is successful namely neither errors nor warnings, the compilation buffer will disappear after 1 second. Stolen from stackoverflow. 

(defun sk-bury-compile-buffer-if-successful (buffer string)
  "Bury a compilation buffer if succeeded without warnings "
  (if (and
       (string-match "compilation" (buffer-name buffer))
       (string-match "finished" string)
       (not
        (with-current-buffer buffer
          (search-forward "warning" nil t))))
      (run-with-timer 1 nil
                      (lambda (buf)
                        (bury-buffer buf)
                        (switch-to-prev-buffer (get-buffer-window buf) 'kill))
                      buffer)))
(add-hook 'compilation-finish-functions 'sk-bury-compile-buffer-if-successful)

cpputils-cmake

From https://github.com/redguardtoo/cpputils-cmake 

(add-hook 'c++-mode-hook (lambda () (cppcm-reload-all)))
(setq cppcm-build-dirname "__build-Linux-x86_64")

Tags

The following code makes use to etags program to generate a list of tags and to ease the code navigation.

Create TAGS table

(defun sk-create-tags(dirname name)
  "Create tags file."
  (interactive "DDirectory: \nsName suffix: ")
  (shell-command
   (format "find %s -type f \\( -name '*.cc' -o -name '*.h' \\) | etags - && mv %s/TAGS %s/TAGS-%s" dirname default-directory temporary-file-directory name)))

Set TAGS filename

(setq tags-file-name (concat temporary-file-directory "TAGS"))

No indentation within namespace block

(defconst my-cc-style
  '("cc-mode"
    (c-offsets-alist . ((innamespace . [0])))))

(c-add-style "my-cc-mode" my-cc-style)
