Are there any examples for streaming the output of a command?

That is, if I do SSHKit.run("wget someaddress.com/file"), can we stream the output as it comes in rather than wait for it to all completely finish?

Great question! 💚

If you look at SSHKit.SSH.run/3, it allows you to pass a :fun option (for maximum fun 😁).
The default for that is to capture/2 all of the output into a list.

You might be able to do streaming with this lower-level API by providing a custom function there for now? 🤔

Otherwise, I've actually been thinking about changing SSHKit's interface to behave more similar to that of mint, i.e. the process that calls SSHKit.run/2 would just receive messages as a result.

Happy if you could provide feedback on both a potential solution with the current API and maybe thoughts on the idea of a mint-like interface. ✌️

There has not been any activity/feedback on this in more than a year, so I will go ahead and close this.
Please feel free to re-open, Carter, in case we can be of help.

In the meanwhile, we're working on a new version of the package which should make it easier to stream output directly. You can follow the work in this PR if you're interested: #164

There are some working examples showcasing the new APIs. It's still a work-in-progress, but might give you some ideas:
