When Log and TailOptions are used by other classes it is now more obvious that they're not hard lined to Tail.
FileTail is heavily based on Tail but I saw no obvious way to abstract the common parts of the classes to not duplicate them. FileTail is so small it's hardly noticeable anyway.

There was a problem hiding this comment.
I'm sorry for the delayed reply.
This feature will also be great for testing templates 👍. I would like to incorporate this feature, but I would like to confirm that at least one other maintainer agrees before proceeding. @floryut @rkmathi @superbrothers What do you think?
Thanks for the PR!
Also moving file tailing to main thread as there are no parallel tails with that config.

Usage:
This PR adds the
--stdinflag for parsing logs fromstdininstead of pulling them from k8s. It creates a new "tail" struct,FileTail, which is heavily based on the originalTail. The new class is quite slim and I didn't find any meaningful way to combine the two, so they are mostly their own separate thing. They do share some helper functions andTailOptionswhich I moved to a "utils" file.It's not uncommon for CLI tools to use
-to read fromstdinbut I didn't find support for that inpflag, and I'm not sure it's better than--stdinanyway. (e.g like vimecho "Hello" | vim -, and for sternstern - < ./service.log)Feedback welcome.
Implements #291
