Haskell: ctag(和Kate编辑器)

Question

我尝试了CTags插件的凯特编辑。它有点工作，索引构建静默(没有错误消息)，数据库文件以及必要的菜单项出现。然后是Go to definition - No hits found。

我并不感到太惊讶。显然，凯特是这样构建索引的：

ctags -R --c++-types=+px --extra=+q --excmd=pattern --exclude=Makefile --exclude=.

这让人联想到C++；我不能说更多。Haskell ctag的正确命令行是什么？

更新：

已经提出了hasktags。我设法安装并试运行了它：

$ stack exec hasktags
Usage: hasktags [OPTION...] [files or directories...]
directories will be replaced by DIR/**/*.hs DIR/**/*.lhs
Thus hasktags . tags all important files in the current
directory.

    If directories are symlinks they will not be followed
unless you pass -L.

A special file "STDIN" will make hasktags read the line separated file
list to be tagged from STDIN.

  -c            --ctags                        generate CTAGS file (ctags)
  -e            --etags                        generate ETAGS file (etags)
  -b            --both                         generate both CTAGS and ETAGS
  -a            --append                       append to existing CTAGS and/or ETAGS file(s). Afterward this file will no longer be sorted!
                --ignore-close-implementation  ignores found implementation if it is closer than 7 lines - so you can jump to definition in one shot
  -o            --output=                      output to given file, instead of 'tags', '-' file is stdout
  -f            --file=                        same as -o, but used as compatibility with ctags
  -x            --extendedctag                 Generate additional information in ctag file.
                --cache                        Cache file data.
  -L            --follow-symlinks              follow symlinks when recursing directories
  -S[.hs,.lhs]  --suffixes[=.hs,.lhs]          list of hs suffixes including "."
  -R            --tags-absolute                make tags paths absolute. Useful when setting tags files in other directories
  -h            --help                         This help

在Kate CTags database file中也有一些路径。

/home/alexey/.local/share/kate/katectags/session_db_20171216_180641

我不能从hasktags自述文件中得到太多信息。

我在.zshrc中使用了hasktag和外壳函数来简化操作：

hasktags --ignore-close-implementation --ctags .
