minetest servers CLI search tool

[erlehmann]

The tool is called minetest-servers and is written in Python 3.
Given no argument, it outputs an annoying licensing & usage text.

Code: Select all

; minetest-servers
minetest-servers – output info about minetest servers

No argument given. Valid arguments:
	address can_see_far_names clients clients_list clients_max clients_top creative damage dedicated description game_time gameid geo_continent ip lag mapgen mods name password ping pop_v port privs proto proto_max proto_min pvp rollback server_id start total_clients update_time updates uptime url version

Given an argument, the tool outputs tab-separated-lines with two fields:
The first field is the server hostname & the second is the value queried.

Code: Select all

; minetest-servers clients |head
jt2.intraversal.net:30002	19
your-land.de:30000	15
server.minetest.one:30001	15
ugxaero.dynu.net:33151	10
ctf.rubenwardy.com:30001	8
edgy1.net:30025	37
skyblock.telesight.nl:30011	7
linux-forks.de:30000	6
80.240.216.69:30002	6
joesworld.zapto.org:30001	5

In case of a list value, there can be multiple lines for the same hostname.

Code: Select all

; minetest-servers clients_list |head
jt2.intraversal.net:30002	Minear105
jt2.intraversal.net:30002	paul
jt2.intraversal.net:30002	why
jt2.intraversal.net:30002	ojvkh
jt2.intraversal.net:30002	Stalma0
jt2.intraversal.net:30002	Mclaen386
jt2.intraversal.net:30002	TUGA
jt2.intraversal.net:30002	CRIATIAN
jt2.intraversal.net:30002	Guitard484
jt2.intraversal.net:30002	kdj

This structure makes it possible to filter results easily.

You can find where another user plays right now:

Code: Select all

; minetest-servers clients_list |grep paul
jt2.intraversal.net:30002	paul

You can find out how many servers use a particular mod:

Code: Select all

; minetest-servers mods |cut -f2 |grep -c '^doors$'
128

In case you feel lonely, you can even find a dating server:

Code: Select all

; minetest-servers description |grep -i dating
oy.edgy1.net:30420	Mineclonia anarchy server: dating hack greef kill ok. No moderation. No rules except don't mess with server operation.  Discord: https://discord.gg/pwgbUdH9Fp IRC: #oysterity on irc.libera.chat. This is the spiritual successor of Clamity anarchy.

Here is the full code of the program – save it as minetest-servers
and then make it executable using

Code: Select all

chmod a+x minetest-servers

.

Code: Select all

Nice one! First time I see the power or Lispython :D

Code: Select all

def get_keys(servers):
    return set(
        [
            item
            for sublist
            in [
                list(dict_keys)

mhh should I consider, server admin LinuxForks.de as on the right way to anonymize his gamer ?
And I also got some steps to that point ...

just funny you used paul ...
copied it, before maybe get forbidden ... but your are right, easy to use the list for

as even I told last that it is easy to generate a gamer profile as of what server play and what time out of this

thanks to proof my ... thoughts
