Emacs:为每个缓冲区设置编译命令 [英] Emacs: set compilation command per-buffer

问题描述

所以，假设我有一个文件 file.c 和一个文件 anothr.c.我想分别为每个文件设置编译命令，例如:gcc -Wall -O3 -of file.c 和 gcc -Wall -std=c99 -oa 另一个.c.如何为该缓冲区设置 gcc 命令，以便每次打开它时，它都知道如何编译它?//-*- 指令或类似的东西有什么吗?谢谢.

so, suppose I have a file file.c, and a file anothr.c. I would like to set the compilation command for each of those files separately, say: gcc -Wall -O3 -o f file.c, and gcc -Wall -std=c99 -o a another.c. How can I set the gcc command for that buffer so that every time I open it, it knows how to compile it? Is there something with the // -*- directive or something like that? Thanks.

推荐答案

是的，您可以使用文件中的指令，也可以设置其他值.在第一或第二行试试这个:

Yes, you can use the directive in the file, and also set other value. Try this in line one or two:

// -*- compile-command: "gcc -Wall -O3 -o f file.c" -*-

然后用C-x v重新加载文件，使设置生效.

and then re-load the file with C-x v so that the setting takes effect.

我有时会设置诸如 c-indent-level: 4;c-basic-offset: 4; 也在里面.

I sometimes set things like c-indent-level: 4; c-basic-offset: 4; in there too.
