Parsing one or more networks in ConfParser

General Usage
1

I’m writing a config file parser using ConfParser for a config file which includes, among other things, the latitude, longitude, and networks from which clients may connect. The file looks like this:

Latitude 35.snip
Longitude -81.snip
ClientNet puma/24,puma/64

puma is the computer I’m running this on, and both IPv4 (192.168.1.0/24) and IPv6 netblocks are allowed to connect. Someone may have only one netblock that may connect. Here’s the code:

"""
    getLatitude()

Gets the latitude from a configuration file. The latitude should be written
in degrees with decimals or degrees:minutes:seconds.
"""
function getLatitude()
  ret=NaN
  for c in confs()
    str=retrieve(c,"Latitude")
    try
      ret=dms2rad(str)
    catch
    end
  end
  ret
end

"""
    getLongitude()

Gets the longitude from a configuration file. The longitude should be written
in degrees with decimals or degrees:minutes:seconds.
"""
function getLongitude()
  ret=NaN
  for c in confs()
    str=retrieve(c,"Longitude")
    try
      ret=dms2rad(str)
    catch
    end
  end
  ret
end

# snip parseNetblock(str::String) -> Vector{IPNet}

function getClientNet()
  ret=IPNet[]
  for c in confs()
    str=retrieve(c,"ClientNet")
    if str>""
      nets=split(str,',')
      for net in nets
	try
	  append!(ret,parseNetblock(net))
	catch
	end
      end
    end
  end
  ret
end

This gave an error at if str>"" because str is not a String but a Vector{String}. So I tried retrieving the lines from the configuration. I got this:

julia> retrieve(EAConfig.confs()[1],"ClientNet")
2-element Vector{String}:
 "puma/24"
 "puma/64"

julia> retrieve(EAConfig.confs()[1],"Latitude")
"35.snip"

I then tried retrieve with a type argument:

julia> retrieve(EAConfig.confs()[1],"ClientNet",String)
ERROR: MethodError: no method matching parse(::Type{String}, ::Vector{String})
julia> retrieve(EAConfig.confs()[1],"Latitude",Vector{String})
ERROR: MethodError: no method matching parse(::Type{Vector{String}}, ::String)

How do I either get the string including the comma, or get a vector of strings, with only one string in the vector if there is no comma?

I’m going to temporarily have two ClientNet lines, but I’d rather have just one.

Two ClientNet lines did not work. I ran this command:

julia> @edit retrieve(confs()[1],"ClientNet")

Looking at the source code, I made this change:

nets=c._data["ClientNet"]

Now it works. It may be broken by a future version of ConfParser though.
