Emacs 缩进难度

Question

我真的很想切换到 emacs，但是学习设置环境真的很痛苦。
每个人都说值得，所以我继续。

我希望我的 c 代码以这种方式实现:

if(asdf)
{
    asdr = 1;
}

根据当前的标准(我知道，不要让我开始)，可能是:

if(asdf) {
    asdr = 1;
}

我似乎无法从 2 更改缩进大小，它看起来总是像 GNU 标准:

if(asdf)
  {
    asdr = 1;
  }

，我不喜欢。
这是我在 .emacs 中放入的内容:

; Warn in C for while();, if(x=0), ...
(global-cwarn-mode 1)

; no electric mode in c
(c-toggle-electric-state -1)
; indent the current line only if the cursor is at the beginning of the line
(setq-default c-tab-always-indent nil)
(setq-default c-indent-level 4)
(setq-default tab-width 4)
(setq-default indent-tabs-mode nil)
(setq-default c-basic-offset 4)
(setq-default c-basic-indent 4)
; These commands I read about on the web, but they don't work?
;(highlight-tabs)
;(highlight-trailing_whitespace)

这没有帮助，我还有 GNU 缩进。
任何人？

您的默认设置可能会被 cc-mode 覆盖的风格特征。

尝试像这样初始化默认样式:
(setq c-default-style '((java-mode . "java") (awk-mode . "awk") (other . "user")))
您应该能够将前一行粘贴到您的 .emacs 文件中，或者自定义 c-default-style多变的。默认有 (other "gnu")作为列表的最后一个元素，这意味着所有非 Java 和非 awk 文件都获得 gnu样式而不是您设置的样式 setq .特价user style 从您手动设置的样式变量中初始化。

另一种选择是选择一种内置样式而不是自己定义它，或者使用 c-add-style 创建自己的样式。功能。为此，请更改 "user"在上面的命令中添加样式的名称(作为字符串)。试试 stroustrup或 python内置样式以您想要的方式格式化 if 语句。
