zigdig

naive dns client library in zig

what does it do

• serialization and deserialization of dns packets as per rfc1035
• supports a subset of rdata (A and AAAA are there, so, for most cases, this will be enough)
• has helpers for reading /etc/resolv.conf (not that much, really)

what does it not do

• no edns0
• can deserialize pointer labels (seamless for library user), but does not serialize into pointers
• follow CNAME records

how do

• zig zag zog https://ziglang.org
• have a /etc/resolv.conf
• (theoretical) posix os w/ sockets, tested on linux
• have The Internet (TM) at your disposal

zig build test

# on debug mode it gets debug stuff to stdout. compile in
# release-safe or above if you're not developing with this lib
zig build install --prefix ~/.local/

using the library

TODO docs

it is recommended to look at zigdig's source on src/main.zig to understand how things tick using the library, but it boils down to three things:

• packet generation and serialization
• sending/receiving (via a small shim on top of std.os.socket)
• packet deserialization
