在写简单的,一个文件,C++代码的时候,我一般直接调用g++。默认情况下,Flymake 似乎假设存在带有检查语法目标的 Makefile。如何将 Flymake 配置为直接调用 g++,例如:
g++ -c a.cpp
如果可以修改答案以包含编译器标志,那就更好了
非常感谢
您可以使用以下 flymake 配置直接调用 g++。
(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$" flymake-cc-init) flymake-allowed-file-name-masks)
(add-hook 'c++-mode-hook 'flymake-mode)
我打电话时收到以下屏幕截图flymake-allowed-file-name-masks
以下为评论版。
;; Import flymake
(require 'flymake)
;; Define function
(defun flymake-cc-init ()
(let* (;; Create temp file which is copy of current file
(temp-file (flymake-init-create-temp-buffer-copy
'flymake-create-temp-inplace))
;; Get relative path of temp file from current directory
(local-file (file-relative-name
temp-file
(file-name-directory buffer-file-name))))
;; Construct compile command which is defined list.
;; First element is program name, "g++" in this case.
;; Second element is list of options.
;; So this means "g++ -Wall -Wextra -fsyntax-only tempfile-path"
(list "g++" (list "-Wall" "-Wextra" "-fsyntax-only" local-file))))
;; Enable above flymake setting for C++ files(suffix is '.cpp')
(push '("\\.cpp$" flymake-cc-init) flymake-allowed-file-name-masks)
;; Enable flymake-mode for C++ files.
(add-hook 'c++-mode-hook 'flymake-mode)
