% This predicate is used for asserting that the Expected value is equal to the Actual value.
% Expected: The value that is expected.

% This predicate asserts that the Expected value is equal to the Result of evaluating Actual.
% Expected: The value that is expected.
% Actual: The expression whose evaluation is being checked against the Expected value.
% Result: The result of the evaluation of the equality.
% Example: If Actual evaluates to the Expected value, this would succeed, setting Result to true (or some success indicator).

% `assertFalse` Predicate
% This predicate is used to assert that the evaluation of EvalThis is false.
% EvalThis: The expression that is being evaluated and checked for falsehood.
% Result: The result of the evaluation.

% This predicate asserts that the Expected value is not equal to the Actual value.

'assertTrue'(EvalThis, Result):- eval_H(['assertTrue', EvalThis], Result).
% `rtrace` Predicate
% This predicate is likely used for debugging; possibly for tracing the evaluation of Condition.
% Condition: The condition/expression being traced.

% Example: `rtrace((2 + 2), EvalResult).` would trace the evaluation of 2 + 2 and store its result in EvalResult.
'rtrace'(Condition, EvalResult):- eval_H(['rtrace', Condition], EvalResult).
% `time` Predicate
% This predicate is used to measure the time taken to evaluate EvalThis.

% Measures the execution time of a Prolog goal and displays the duration in seconds,
% milliseconds, or microseconds, depending on the execution time.
%
% Args:
% - Goal: The Prolog goal to be executed and timed.
%
% The predicate uses the `statistics/2` predicate to measure the CPU time before
% and after executing the provided goal. It calculates the elapsed time in seconds
% and converts it to milliseconds and microseconds. The output is formatted to
% provide clear timing information:
%
% - If the execution takes more than 2 seconds, it displays the time in seconds.
% - If the execution takes between 1 millisecond and 2 seconds, it displays the time
% in milliseconds.
% - If the execution takes less than 1 millisecond, it displays the time in microseconds.
%
% Example usage:
% ?- time_eval(my_goal(X)).
%
% ?- time_eval(sleep(0.95)).
%
% Output examples:
% ; Evaluation took 2.34 seconds.
% ; Evaluation took 123.45 ms.
% ; Evaluation took 0.012 ms. (12.33 microseconds)
