Display a version number for Lua dissector?

example in Lua-script:

local my_info = 
{
    version = "1.0.1",
    author = "Jane Doe",
    description = "this plugin parses rainbows",
    repository = "https://github.com/octocat/Spoon-Knife"
}
set_plugin_info(my_info)

C-code from wirshark source:

WSLUA_FUNCTION wslua_set_plugin_info(lua_State* L) {
55     /*  Set a Lua table with meta-data about the plugin, such as version.
56
57         The passed-in Lua table entries need to be keyed/indexed by the following:
58          * "version" with a string value identifying the plugin version (required)
59          * "description" with a string value describing the plugin (optional)
60          * "author" with a string value of the author's name(s) (optional)
61          * "repository" with a string value of a URL to a repository (optional)
62
63         Not all of the above key entries need to be in the table. The 'version'
64         entry is required, however. The others are not currently used for anything, but
65         might be in the future and thus using them might be useful. Table entries keyed
66         by other strings are ignored, and do not cause an error.

I'd suggest installing and checking out cloudshark wireshark plugin (written in lua)

https://support.cloudshark.org/wireshark-plugin/using-the-wireshark-plugin.html

And then when you have it installed have a look at their source code.

They've added their own menu, preferences settings and their own about window.
