I tried the above, but, when Wireshark is started, it actually throws
the error at:

"~/.luarocks/share/lua/5.1/luacov/hook.lua:26:attempt to index global
'debug' (a function value)".

In hook.lua, when the local variable "name" is assigned to the full
path of the Lua plugin prefixed by "@", the coverage statistics get
generated. Bascially, the following is used to retrieve the name:

  local name = debug.getinfo(level, "S").source -- returns "@dissector.lua"

So, the following hard-coded assginment works:

  local name = "@dissector.lua"
  local prefixed_name = string.match(name, "^@(.*)")

I am not sure why debug module or function is used to retrieve the
path to the Wireshark Lua plugin. Will check with the Luacov author.

Thanks for your reply. Appreciate it!
