Emacs最快的C ++编译过程? [英] Emacs fastest C++ compilation process?
问题描述
这里的用例:我阅读了一篇关于C ++
的技术博客的文章(多重继承失败和多线程等:)。
通常它们带有一些代码。它几乎总是一个文件,我几乎总是
想运行它,并玩弄它。
Here's the use case: I read an articles on tech blogs about C++ (fails of multiple inheritance this and multi-threading that etc.:). Usually they come with some code. It's almost always one file and I almost always want to run it and play around with it.
我想用Emacs做,我想做
I want to do it with Emacs and I want to do it FAST, as in with the least (or reasonably few) keystrokes.
所以假设我已经创建了一个 multiple_inheritance,它是FAST,
文件放在自己的文件夹
。 cc
中并粘贴代码。
So suppose I've already created a multiple_inheritance.cc
file in its own folder
and pasted the code. How do I get to an executable really fast?
这是我现在正在做的事(希望有人会改进它。)
Here's what I'm doing now (hopefully someone will improve it.)
(defun cpp-generate-makefile ()
(interactive)
(let* ((n-buffer (buffer-file-name))
(n-file (file-name-nondirectory n-buffer))
(n-target (file-name-sans-extension n-file))
(n-makefile (concat (file-name-directory n-buffer) "Makefile")))
(if (file-exists-p n-makefile)
(when (called-interactively-p 'any)
(message "Makefile already exists"))
(with-current-buffer (find-file-noselect n-makefile)
(insert
(concat n-target ": " n-file
"\n\tg++ -g -O2 -std=c++0x -o $@ $^\n\n"
"clean: \n\trm -f " n-target "\n"))
(save-buffer)))))
(defun cpp-run ()
(interactive)
(save-buffer)
(cpp-generate-makefile)
(compile "make"))
(add-hook 'c++-mode-hook
(lambda()
;; ...
(define-key c++-mode-map [f5] 'cpp-run)))
这里有一些东西我现在慢了:
Here's a few things that SLOW me down currently:
-
compile
- 我想要在
* compilation * $ c>中指定一个开头的文件$ c>缓冲区,以防万一出现错误。
我查看了compile.el
,它定义了compilation-num-errors-found
- 另一方面,如果没有错误(我只需要一个谓词),
b为什么不启动term
并运行程序?
compile
asks if I want to save any open files that are totally unrelated to C++.- I'd like to have the point in
*compilation*
buffer in case there was an error. I've looked intocompile.el
, which hascompilation-num-errors-found
defined, but that variable isn't used anywhere in that file. - On the other hand, if there were no errors (I just need a predicate for this),
why not launch
term
and run the program?
推荐答案
我更新了代码,我必须添加运行
目标到 Makefile
。
我还添加了一个扩展C:
I've updated the code I had to add a run
target to Makefile
.
I've also added an extension to C:
(defvar cpp-generate-compiler "g++ -g -O2 -std=c++0x")
(defun cpp-generate-makefile ()
(interactive)
(let* ((n-buffer (buffer-file-name))
(n-file (file-name-nondirectory n-buffer))
(n-target (file-name-sans-extension n-file))
(n-makefile (concat
(file-name-directory n-buffer)
"Makefile")))
(if (file-exists-p n-makefile)
(when (called-interactively-p 'any)
(message "Makefile already exists"))
(with-current-buffer (find-file-noselect n-makefile)
(insert
(concat n-target ": " n-file
(format "\n\t%s -o $@ $^"
cpp-generate-compiler)
"\n\nclean: \n\trm -f " n-target
"\n\nrun: " n-target "\n\t ./" n-target
"\n\n.PHONY: clean run\n"))
(save-buffer)))))
(defun cpp-run ()
(interactive)
(save-buffer)
(cpp-generate-makefile)
(compile "make run"))
(defun c-run ()
(interactive)
(let ((cpp-generate-compiler "gcc -g -O2 -std=c99"))
(cpp-run)))
(add-hook 'c++-mode-hook
(lambda()
;; ...
(define-key c++-mode-map [f5] 'cpp-run)))
(add-hook 'c-mode-hook
(lambda()
;; ...
(define-key c-mode-map [f5] 'c-run)))
(setq compilation-ask-about-save nil)
(setq compilation-finish-functions
(list (lambda(buffer str)
(unless (string= str "finished\n")
(push-mark)
(next-error)))))
( cpp-run
自动保存)。
我只记得 Mg n 和 Mg p
导航错误。
And I just have to remember that M-g n and M-g p navigate the errors.
现在我的过程是最优的:从源代码中的一个键,以便有没有错误的
。
Now my process is neary optimal: one key from source to result in case there are no errors.
case有错误,它是额外的 Mg n 。
现在,如果只有一种方法 compile
调用(push-mark)(下一个错误)
...
In case there are errors, it's an extra M-g n.
Now, if only there was a way for compile
to call (push-mark)(next-error)
...
感谢@juanleon的建议, / p>
Thanks to suggestion of @juanleon, this is solved with:
(setq compilation-finish-functions
(list (lambda(buffer str)
(unless (string= str "finished\n")
(push-mark)
(next-error)))))
但是由于某种原因, push-mark
在这种情况下无法正常工作。
But for some reason, push-mark
doesn't work properly in this case.
