如何更改Emacs自动恢复文件的名称？ [英] How do I change the name of Emacs auto-recovery file?

问题描述

目前，它以格式保存文件：

 。＃main.c  - > [e-mail].27017：1231918415 
  

这使它成为问题，因为它结束。 c。

我需要它。＃main.c＃

更新：我有emacs 22.1

解决方案

这不是自动恢复文件，这是用作该文件的锁定令牌的链接。

如果我告诉你，你能介绍一下Summer Glau吗？

这可能不是容易改变的;我只是挖了一下，看起来像是在C代码中设置的。但是让我们问下一个问题：你为什么要这样？我猜你正在使用 .c 正则表达式，您不想与之匹配。如果是这样，请注意，所有这些锁定文件链接以开始。＃ - 总是硬编码 - 所以你可以总是排除名称匹配^。＃的文件取决于你使用哪个正则表达式语法。）

如果你真的想破解它，它在filelock.c在EMACS 22中的第320行。这是代码：

  / *将FN的锁定文件的名称写入LFNAME。长度将为
，FN加上另外两个为领先的`。＃'加1为
的结尾期加上一个为数字后加上一个为
 null。 * / 
 #define MAKE_LOCK_NAME（lock，file）\ 
（lock =（char *）alloca（SBYTES（file）+ 2 + 1 + 1 + 1），\ 
 fill_in_lock_file_name （lock，（file）））
 
 static void 
 fill_in_lock_file_name（lockfile，fn）
 register char * lockfile; 
注册Lisp_Object fn; 
 {
注册char * p; 
 struct stat st; 
 int count = 0; 
 
 strcpy（lockfile，SDATA（fn））; 
 
 / *将文件名的非目录部分（包括null）
右移两个字符。这里是我们必须
做一些支持14个字符的最大文件名的地方之一。 * / 
 for（p = lockfile + strlen（lockfile）; p！= lockfile& * p！='/'; p--）
 p [2] = * p; 
 
 / *插入`。＃'。 * / 
 p [1] ='。' 
 p [2] ='＃'; 
 
 p = p + strlen（p）; 
 
 while（lstat（lockfile，& st）== 0&！S_ISLNK（st.st_mode））
 {
 if（count> 9）
 {
 * p ='\0'; 
 return; 
} 
 sprintf（p，。％d，count ++）; 
} 
} 
  

At the moment it saves the file with format:

.#main.c -> [e-mail].27017:1231918415

This makes it problematic since it ends with ".c".

I need it to be .#main.c#

Update: I have emacs 22.1

解决方案

That's not the auto-recovery file, that's the link used as a locking token for the file.

If I tell you, will you introduce me to Summer Glau?

It's probably not going to be easy to change that; I just dug a bit and it looks like it's set in the C code. But let's ask the next question: why do you want to? I'm guessing you're hitting a regular expression for .c files that you don't want to match these. If so, note that all these lockfile links start with .# -- invariably, that's hardcoded -- so you could always exclude files with names that match "^.#" (depending on which regex syntax you use.)

If you really want to hack at it, it's in filelock.c at about line 320 in EMACS 22. Here's the code:

/* Write the name of the lock file for FN into LFNAME.  Length will be
   that of FN plus two more for the leading `.#' plus 1 for the
   trailing period plus one for the digit after it plus one for the
   null.  */
#define MAKE_LOCK_NAME(lock, file) \
  (lock = (char *) alloca (SBYTES (file) + 2 + 1 + 1 + 1), \
   fill_in_lock_file_name (lock, (file)))

static void
fill_in_lock_file_name (lockfile, fn)
     register char *lockfile;
     register Lisp_Object fn;
{
  register char *p;
  struct stat st;
  int count = 0;

  strcpy (lockfile, SDATA (fn));

  /* Shift the nondirectory part of the file name (including the null)
     right two characters.  Here is one of the places where we'd have to
     do something to support 14-character-max file names.  */
  for (p = lockfile + strlen (lockfile); p != lockfile && *p != '/'; p--)
    p[2] = *p;

  /* Insert the `.#'.  */
  p[1] = '.';
  p[2] = '#';

  p = p + strlen (p);

  while (lstat (lockfile, &st) == 0 && !S_ISLNK (st.st_mode))
    {
      if (count > 9)
    {
      *p = '\0';
      return;
    }
      sprintf (p, ".%d", count++);
    }
}
