Compiling the whole tui stack, just to debug the lua command line seems
counterproductive to me. This allows to just compile the needed parts
for a basic lua repl.
As of yet the repl is just a mock-up, as the event handling can, as of
right now, not easily be separated from the tui.
To activate specific features add specify the on the cargo command line
like this:
```
cargo run --features "cli tui"
```
or add them to the `default` feature set in the `Cargo.toml`.
Wildcard version is comparable to selecting a version depending on
the result of a dice roll. What I mean with this is, that the version
will be selected based on what the specific user already has in their
cargo registry. This means that the same codebase will compile
wonderfully on one machine but will fail with weird errors like:
`the trait 'From<crossterm::event::Event>' is not implemented for 'Input'`
on an other one.
Additionally crates.io does not accept crates with a bare wildcard
version requirement for aforementioned reasons.
Lastly using direct versions requirement allows to use `cargo upgrade`
to automatically update these requirements to their highest possible
value, as determined by SemVer. This works especially well, when adding
new dependencies with `cargo add`, as this also adds a direct version
requirement.
