# awl: drill, writ small (and using deno)
|
||||
|
||||
Install:
|
||||
`deno install --allow-net https://git.froth.zone/sam/awl/raw/branch/master/awl.ts`
|
||||
# awl
|
||||
|
||||
`awl` is a command-line DNS client, much like
|
||||
[`drill`](https://github.com/NLnetLabs/ldns),
|
||||
[`dig`](https://bind9.readthedocs.io/en/v9_18_3/manpages.html#dig-dns-lookup-utility),
|
||||
[`dog`](https://github.com/ogham/dog),
|
||||
[`doggo`](https://github.com/mr-karan/doggo),
|
||||
or [`q`](https://github.com/natesales/q)
|
||||
|
||||
The excellent [dns](https://github.com/miekg/dns) library for Go does most of the heavy
|
||||
lifting.
|
||||
|
||||
## What works
|
||||
|
||||
- UDP
|
||||
- TCP
|
||||
- TLS
|
||||
- HTTPS (maybe)
|
||||
|
||||
## What doesn't
|
||||
|
||||
- DNS-over-QUIC (eventually)
|
||||
- Your sanity after reading my awful code
|
||||
- A motivation for making this after finding q and doggo
|
||||
|
||||
## What should change
|
||||
|
||||
- Make the CLI less abysmal (migrate to [cobra](https://github.com/spf13/cobra)?
|
||||
or just use stdlib's flags)
|
||||
- Optimize everything
|
||||
- Make the code less spaghetti
|
||||
- Like not just having one massive unreadable file, this is AWFUL
|
||||
- Documentation, documentation, documentation
