R阅读T他F奇妙的M年度应该永远尝试解决问题的第一步。
来自$ man ctags:
--exclude=[pattern]
Add pattern to a list of excluded files and directories. This option may
be specified as many times as desired. For each file name considered by
both the complete path (e.g. some/path/base.ext) and the base name (e.g.
base.ext) of the file, thus allowing patterns which match a given file
name irrespective of its path, or match only a specific path. If appro-
priate support is available from the runtime library of your C compiler,
then pattern may contain the usual shell wildcards (not regular expres-
sions) common on Unix (be sure to quote the option parameter to protect
the wildcards from being expanded by the shell before being passed to
ctags; also be aware that wildcards can match the slash character, '/').
You can determine if shell wildcards are available on your platform by
examining the output of the --version option, which will include "+wild-
cards" in the compiled feature list; otherwise, pattern is matched
against file names using a simple textual comparison.
If pattern begins with the character '@', then the rest of the string is
interpreted as a file name from which to read exclusion patterns, one per
line. If pattern is empty, the list of excluded patterns is cleared.
Note that at program startup, the default exclude list contains "EIFGEN",
"SCCS", "RCS", and "CVS", which are names of directories for which it is
generally not desirable to descend while processing the --recurse option.
从你得到的前两句话:
$ ctags -R --exclude=dir1 --exclude=dir2 --exclude=dir3 .
这可能有点冗长,但这就是别名和映射等的用途。作为替代方案,您可以从第二段中得到:
$ ctags -R --exclude=@.ctagsignore .
在.ctagsignore:
dir1
dir2
dir3
这可以排除这 3 个目录而无需输入那么多内容。
