如果您使用强大的ctag生成标记文件(有其他方法吗?)然后尝试添加
--extra=+f
选项。有关详细信息,请参见http://ctags.sourceforge.net/ctags.html#OPTIONS上的手册页。旺盛的标记(带有
--extra=+f
)为python文件名(例如my_module.py
)生成标记,而不是为模块名(例如my_module
)生成标记。我最终创建了ptags脚本的修改版本。将以下内容保存到路径中名为ptags
的文件中,并使其可执行:现在运行以下命令,通过递归处理当前目录生成标记文件:
ptags -R -f tags_file_to_create /path/to/index
