ctags不使用我在Mac上的自定义.ctags

Question

我正在尝试在Mac OS上使用exuberant ctag。我已经在homebrew上安装了exuberant ctag。以下是我的版本：

$ ctags --version
Exuberant Ctags 5.8, Copyright (C) 1996-2009 Darren Hiebert

我的自定义$HOME/.ctags似乎没有被考虑在内。

下面是我的配置：

$ cat ~/.ctags
--verbose=no
--recurse=yes
--tag-relative=yes
--langdef=scala
--langmap=scala:.scala
--regex-scala=/^\s*class\s*([a-zA-Z0-9_]+)/\1/c,classes/
…

当我启动ctags -R时，没有为.scala文件生成标签。

当我使用--options进行测试时

$ctags -R --options=/Users/yamo/.ctags
ctags: cannot open option file "/Users/yamo/.ctags" : No such file or directory

$ll ~/.ctags
lrwxr-xr-x  1 yamo  staff  36 Apr 13 21:29 /Users/yamo/.ctags@ -> /Users/yamo/Projects/dotfiles/.ctags

Answer 1

该问题是由于BSD Regex造成的。

我刚刚通过在Vim :%s/\\s/[ \\t]/g中编辑~/.ctags解决了这个问题

Answer 2

根据文档，您应该将配置文件放在~/.ctags.d/文件夹下。我也遇到了同样的问题，这样做对我来说也是有效的：

   $HOME/.ctags.d/*.ctags

   $HOMEDRIVE$HOMEPATH/ctags.d/*.ctags (on MSWindows only)

   .ctags.d/*.ctags

   ctags.d/*.ctags
      If any of these configuration files exist, each will be expected to contain a set of default options which are read in the order listed when ctags starts, but before the CTAGS
      environment variable is read or any command line options are read. This makes it possible to set up personal or project-level defaults. It is possible to compile ctags to read
      an  additional  configuration  file  before  any  of those shown above, which will be indicated if the output produced by the --version option lists the "custom-conf" feature.
      Options appearing in the CTAGS environment variable or on the command line will override options specified in these files. Only options will be read  from  these  files.  Note
      that  the  option files are read in line-oriented mode in which spaces are significant (since shell quoting is not possible) but spaces at the beginning of a line are ignored.
      Each line of the file is read as one command line parameter (as if it were quoted with single quotes).  Therefore, use new lines to indicate separate  command-line  arguments.
      A line starting with '#' is treated as a comment.

      *.ctags files in a directory are loaded in alphabetical order.

   tags   The default tag file created by ctags.

   TAGS   The default tag file created by etags.
