StormConfig converting uppercase keys to lowercase about storm

[emre]

Let's see if we remove that behavior without breaking anything.

Experienced the same issue on 0.7.0 on both Linux (installed via pip) and macOS (via homebrew).

Lucky that keywords in per-user ssh_config are not case-sensitive (arguments are), it's bad behaviour and should be fixed (also bad for the eyes).

I've wondered if storm could keep a reference of all SSH config keys and their canonical capitalization, then fix them on write. Keeping them all lowercase internally makes it easier to lookup/sort/etc. This man page looks to be the latest, most complete listing of config options: https://man.openbsd.org/ssh_config

Scraping the page gives this list of config options:

And to play along at home:

import re
import httpx
from bs4 import BeautifulSoup

ssh_config_man = httpx.get("https://man.openbsd.org/ssh_config")
soup = BeautifulSoup(ssh_config_man.text)
headers = soup.find_all("a", class_="permalink")

config_keys = [c.text for c in headers if re.match(r"[A-Z]+[a-z]+", c.text)]

Also, a PR similar to this has been open for a long time: #130
I've submitted #174 to implement my fix above.
