✨ NEW: Add verdi tui

[chrisjsewell]

Proof of concept to use https://github.com/Textualize/trogon, a https://github.com/textualize/textual extension, to generate a Textual UI for exploring the verdi command-line interface.
It is a simple way for users to see all the available commands in verdi, without having to dig through the help of each subcommand.

As you see, its is only 2-lines of code, so no real problem in that respect.

But obviously it adds additional dependencies, which has to be considered (and currently is not on conda: Textualize/trogon#49 (comment))

---

In the future, I would also suggest that Textual could be used to write improved interfaces for some of the CLI commands, such as exploring the provenance graph and process statuses.
I think its an interesting middle ground between CLIs, which are lightweight but have limited interactivity, and GUIs which generally require technologies outside of Python, REST APIs, etc

@chrisjsewell Think this is very cool indeed. Maybe we can simply make it an optional requirement by adding the tui extra in the dependencies. Then in the docs, we can add a tip admonition near the install/config instructions to add this in addition to verdi. Question: if you install this, can verdi only be used in the textual way? Or can you still execute commands in the normal way?

Sure

It shouldn't affect normal verdi functioning in any way; just adding the extra tui command

Cheers @chrisjsewell . Made it properly optional by catching import errors and added a note to the docs.
