New command 'alias'

Pre-Check

• did a quick search in current issues first: found nothing related
• I'm willing or interested in helping in implementation

Environment

rebar3 3.22.1 (latest, at this moment)

Current behaviour

No such command exists.

Expected behaviour

I'd like to have a command named alias that'd output the available aliases and what they alias to, similar to zsh's alias.

I'm pretty sure only the aliases in the config file are created, so just expanding the current provider to do something akin to

rebar3/apps/rebar/src/rebar_prv_alias.erl

Lines 16 to 23 in 11c2de0

	init(State) ->
	Aliases = rebar_state:get(State, alias, []),
	lists:foldl(fun({Alias, Cmds}, {ok, StateAcc}) ->
	case validate_provider(Alias, Cmds, State) of
	true -> init_alias(Alias, Cmds, StateAcc);
	false -> {ok, State}
	end
	end, {ok, State}, Aliases).

but with output instead of actual initialization is all that would be required.

I guess it was never created because you can look in the config file(s) to get the same result.

Shouldn't be too complex.

Thank you.

You can look in the config. but if you want something more programmatic, I guess the output should be easier to parse 😄
