Before this commit, we would require those target a specific handler,
whereas they are in fact global to the entire validator.
So now, we recover the behaviour from before where we default to the
only available validator when there's no ambiguity.
Note that this also solves the need for repeatedly applying parameters
to each handler of a parameterized validator. The command now
rightfully apply parameters to each corresponding handler.
For the program to be consistent, the 'EventListener' target that we
pass to a Project should be responsible for the output format.
Otherwise, we are contingent on developers to remember passing the
option at call-site. Plus, it overloads the project code with an extra
boolean option.
Instead, since the behaviour is solely driven by the execution
context, we can instantiate a different event target upfront, and
simply hold on to it throughout the program.
As a nice side-effect, we can gently re-organize the code to keep the
terminal printing logic and the json printing logic separate.
It might be slightly cleaner and more extensible to change to return a summary, potentially even making track the tests, coverage, etc. so it can be serialized to JSON. But, for now, this is much simpler, and the approach that KtorZ suggested.
This is a *slight* hack / abuse of the code() method as we are now
doing a bit of formatting within that function. Yet, we only do so at
the very top-level (i.e. project's Error) because we can't actually
fiddle with how miette presents errors.
Also removed the 'clear' flag to do it by default instead of clogging
the terminal view.
This now works pretty nicely, and the logic is back under
`aiken_project`.
Rather than have this logic in the aiken binary, this provides a generic
mechanism to do "something" on file change events. KtorZ is going to
handle wiring it up to the CLI in the best way for the project.
I tried to write some tests for this, but it's hard to isolate the
watcher logic without wrestling with the borrow checker, or overly
neutering this utility.
