I have always admired the way Ada is designed; its clean, well-organized structure makes it a pleasure both to write and to read. The logically separated sections and block arrangements contribute to an overall elegant coding experience. I am interested in hearing which programming language you find carries a similar sense of visual charm and clarity. Below is an alternative code snippet that demonstrates a simple state-management module with a focus on clean aesthetics:
package VisualModule is
type Mode_Type is (Idle, Low, Normal, High) with Size => 2;
type Input_Flag is (None, Raise, Lower, Dual) with Size => 2;
procedure ExecuteProcess;
private
type Mode_Matrix is array (Mode_Type, Input_Flag) of Mode_Type;
Mode_Map : constant Mode_Matrix := (
Idle => (Idle, Low, Idle, Idle),
Low => (Low, Normal, Idle, Idle),
Normal => (Normal, High, Low, Idle),
High => (High, High, Normal, Idle)
);
end VisualModule;
package body VisualModule is
procedure ExecuteProcess is
CurrentMode : Mode_Type := Idle;
Counter : Natural := 0;
begin
loop
AcquireInput (Signal);
CurrentMode := Mode_Map(CurrentMode, Signal);
UpdateOutput (CurrentMode);
Counter := Counter + 1;
end loop;
end ExecuteProcess;
end VisualModule;
