Added support and a bit of validation and tests.

Let me know if you want something different.

Sorry, something went wrong.

Comment thread lib/pythonx.ex Outdated
Comment on lines +116 to +123
- `["--native-tls"]` - use the system's native TLS implementation instead
of vendored rustls. This is useful in corporate environments where the
system certificate store must be used.
- `["--no-cache"]` - disable the cache, forcing a fresh download of all
packages.
- `["--reinstall"]` - force reinstallation of all packages, even if they
are already present.
- `["--quiet"]` - suppress output from the uv command.

I would prefer to just have an Elixir option :native_tls. This way we have more control over where how and where we pass specific CLI options. Also, we already have :force, so no need to use --no-cache or --reinstall. @josevalim wdyt?

I think I agree, as we cannot guarantee all of the options will work with Pythonx...

Are there other options you would want as part of this PR or just limit it to :native_tls?

Let's do native tls for now. We can add more options if someone has a need for it :)
