配置的Emacs Flymake调用克++直接(Configure Emacs Flymake to

当写简单，一个文件，C ++代码，我通常称之为克++直接。 默认情况下，Flymake似乎假定一个Makefile的存在与检查语法目标。 如何配置Flymake只需拨打G ++直接，如：

g++ -c a.cpp

如果答案可以被修改，以包括编译器标志，这将是更好

非常感谢

Answer 1:

你可以G ++直接与下面的flymake配置调用。

(require 'flymake)

(defun flymake-cc-init ()
  (let* ((temp-file   (flymake-init-create-temp-buffer-copy
                       'flymake-create-temp-inplace))
         (local-file  (file-relative-name
                       temp-file
                       (file-name-directory buffer-file-name))))
    (list "g++" (list "-Wall" "-Wextra" "-fsyntax-only" local-file))))

(push '("\\.cpp$" flymake-cc-init) flymake-allowed-file-name-masks)
(add-hook 'c++-mode-hook 'flymake-mode)

我得到了下面的截图当我打电话flymake-allowed-file-name-masks

以下是评论的版本。

;; Import flymake
(require 'flymake)

;; Define function
(defun flymake-cc-init ()
  (let* (;; Create temp file which is copy of current file
         (temp-file   (flymake-init-create-temp-buffer-copy
                       'flymake-create-temp-inplace))
         ;; Get relative path of temp file from current directory
         (local-file  (file-relative-name
                       temp-file
                       (file-name-directory buffer-file-name))))

    ;; Construct compile command which is defined list.
    ;; First element is program name, "g++" in this case.
    ;; Second element is list of options.
    ;; So this means "g++ -Wall -Wextra -fsyntax-only tempfile-path"
    (list "g++" (list "-Wall" "-Wextra" "-fsyntax-only" local-file))))

;; Enable above flymake setting for C++ files(suffix is '.cpp')
(push '("\\.cpp$" flymake-cc-init) flymake-allowed-file-name-masks)

;; Enable flymake-mode for C++ files.
(add-hook 'c++-mode-hook 'flymake-mode)
