The `Editor` is very useful for correctly opening a text editor and making changes
to some initial input. The current use of `Editor` is only for getting input for
commets.
However, it would also be useful for opening up a text editor on some other
existing files or text, for example, in the command `rad config edit`.
The `Editor` struct was changed to have two new options, `truncate` and
`cleanup`, to allow the user of the struct to dictate whether existing text is
truncated, and if the underlying file should be remove.
The original `new` method is now named `comment`, mimicing the existing
construction of a temporary `RAD_COMMENT` file.
The new version of `new` accepts any file for the `Editor` and will open it
without truncating or removing the file.
`Editor` is now used for the `rad config edit` command.
This is a pager (like `less`) that takes an `Element`, and dynamically
re-renders the element when the terminal size changes. This ensures that
the content is always properly wrapped and rendered.
This allows a user to choose private or public visibility on `rad init`.
It also improves the output to tell the user what happened due to this
choice.
Improvements to the CLI output as well as converging towards
`termion` as a backend.
The crates we were using for prompting and spinners were based on
a terminal backend called `console`, which is not really used
anywhere else. There were also limitations in terms of the output
of these crates.
Therefore, we switched to the `inquire` crate for prompting, using
the `termion` backend, which is very standard.
Additionally, we simplify the terminal output to use symbols:
! for Warning
✓ for Success
✗ for Error
... Instead of a mix of words and symbols.
We also include a modified version of the `yansi` crate which plays
well with our table formatting functions by automatically truncating
and padding output in a unicode-aware way.
