I am creating a TUI library and I have a class with the

class Label : Renderable {
const string text;
const TextAlignment textAlignment;

this(Dimensions dimensions, string text, TextAlignment
textAlignment, Color color) {
this.dimensions = dimensions;
this(text, textAlignment, color);
}
this(string text, TextAlignment textAlignment, Color color)
{
this.text = text;
this.textAlignment = textAlignment;
this.color = color;
}
override Cell[] render() const {
Cell[] cells;
for (int x = 0; x < 0 + text.length; ++x) {
cells ~= Cell(Coordinates(x, 0), text[x], color);
}
return cells;
}
}
```
I am debating whether or not I should add getter methods to
these properties. On one hand, it will inflate the codebase by
a lot, on the other hand -- in other languages like Java it is
a good practice:
```
class Label : Renderable {
private const string text;
private const TextAlignment textAlignment;
private const Color color;
this(Dimensions dimensions, string text, TextAlignment
textAlignment, Color color) {
this.dimensions = dimensions;
this(text, textAlignment, color);
}
this(string text, TextAlignment textAlignment, Color color)
{
this.text = text;
this.textAlignment = textAlignment;
this.color = color;
}
string getText() const {
return text;
}
TextAlignment getTextAlignment() const {
return textAlignment;
}
Color getColor() const {
return color;
}
override Cell[] render() const {
Cell[] cells;
for (int x = 0; x < 0 + text.length; ++x) {
cells ~= Cell(Coordinates(x, 0), text[x], color);
}
return cells;
}
}
```
It's not a lot of code that has been added but if you have a
class with say 10 different fields, adding getter methods would
definitely increase the code size by a lot, so what are you
guys thoughts on this?
Dunno if someone mentioned, but you can minimize use of
boilerplate by hiding it into mixin templates. Say you have:
```D
mixin template Property(T) {
private T subject_;
T Property() { return subject_; }
void Property(T value) { subject_ = value; }
}
```
The you can use it in your class to define properties of class:
```D
class MyMegaPropertyClass {
mixin Property!(string) myFancyProperty;
}
auto c = new MyMegaPropertyClass()
c.myFancyProperty = "indeed"
```
The only issue is that, by using eponymous naming you also block
any access of underlying subject_ or any other miscellaneous info
that you may add.
