5652 :: TXT DNS lookup

  Hi,

  Newbie here - learning from the Nim book and working on pet project. I would love to use nim for networking tools. I've got stuck on making DNS queries. I am surprised there is nothing built into the standard library.

  What is the Nim way of looking up e.g. TXT? Should I be calling C code for it? Has anyone done this before?

  I've tried this, but I cannot believe one has to write a library for DNS lookups (it's also broken):

  Thank you!

  Yeah, there is nothing for this in the stdlib. You will have to call out into posix/win api to do it, if you're up for it contributing this to the stdlib would be much appreciated :)

  On the one side it would be nice to have native DNS lookup code in Nim, as this could play nice with async and could finally make connect() and dial() and friends really asynchronous. The downside is that resolving is historically really a task for the OS, as there are more potential sources for doing lookups (/etc/hosts, DNS cache, LDAP, etc).

  There is also cheatfate's asyncdns in asynctools repo. But have not tried it lately.
