bensie / netaddr Goto Github PK

We recently ran into a problem with this gem where rails would not auto-load it because the namespace and filenames do not follow conventions. Ex (NetAddr => net_addr.rb or netaddr.rb => Netaddr.

If you are currently maintaining the gem, would you be open to a PR to add a shim that adds support for the naming convention? Ex:

in netaddr.rb

# ...

Netaddr = NetAddr

A more radical approach would be to rename the gem to net_addr.

This should merge down to a /8:

irb(main):003:0> NetAddr.merge(['10.0.0.0/8','10.0.0.0/12'])
=> ["10.0.0.0/8", "10.0.0.0/12"]

As should this:

irb(main):009:0> NetAddr.merge(['10.0.0.0/8','10.0.0.0/16'])
=> ["10.0.0.0/8", "10.0.0.0/16"]

This works as expected (example from docs):

irb(main):017:0> NetAddr.merge(['192.168.1.0/26', '192.168.1.64/27',
'192.168.1.96/27', '10.1.0.0/26', '10.1.0.64/26'])
=> ["10.1.0.0/25", "192.168.1.0/25"]

This should merge the 192.168.x.x to the /16:

irb(main):019:0* NetAddr.merge(['192.168.1.0/26', '192.168.1.64/27',
'192.168.1.96/27', '10.1.0.0/26', '10.1.0.64/26', '192.168.0.0/16'])
=> ["10.1.0.0/25", "192.168.0.0/16", "192.168.1.0/25"]

Here is the same idea in perl using Net::CIDR::Set:

$ perl -MNet::CIDR::Set -e '$s =
Net::CIDR::Set->new("10.0.0.0/8","10.0.0.0/12"); printf("%s\n",
join("\n", $s->as_cidr_array()))'
10.0.0.0/8
$ perl -MNet::CIDR::Set -e '$s =
Net::CIDR::Set->new("10.0.0.0/8","10.0.0.0/16"); printf("%s\n",
join("\n", $s->as_cidr_array()))'
10.0.0.0/8
$ perl -MNet::CIDR::Set -e '$s = Net::CIDR::Set->new("192.168.1.0/26",
"192.168.1.64/27", "192.168.1.96/27", "10.1.0.0/26", "10.1.0.64/26");
printf("%s\n", join("\n", $s->as_cidr_array()))'
10.1.0.0/25
192.168.1.0/25
$ perl -MNet::CIDR::Set -e '$s = Net::CIDR::Set->new("192.168.1.0/26",
"192.168.1.64/27", "192.168.1.96/27", "10.1.0.0/26", "10.1.0.64/26",
"192.168.0.0/16"); printf("%s\n", join("\n", $s->as_cidr_array()))'
10.1.0.0/25
192.168.0.0/16
