Standard control

Adama has many control and loop structures similar to C-like languages like:

• if
• while
• do-while
• for

And we introduce two non-traditional ones:

• ifas
• foreach

Diving Into Details

if

if statements are straightforward ways of controlling the flow of execution, and Adama's if behaves like most other languages.

public int x;

@construct {
   if (true) {
     x = 123;
   } else {
   	 x = 42;
   }
}

if-as

Unlike most languages, Adama has a special extension to the if statement which is used for maybe. This allows safely extracting values out from the maybe.

int x;
@construct {
   maybe<int> m_value = 123;
   if (m_value as value) {
     x = value;
   }
}

while

while statements are a straightforward way to iterate while a condition is true.

int x = 10;
int y = 0;
while (x > 0) {
  x --;
  y += x;
}

do-while

do-while statements are a way to run code at least once.

int x = 10;
int y = 0;
do {
  x--;
  y += x;
} while (x > 0);

for

for statements are a common shorthand for while loops to initialize and step.

int y = 0;
for(int x = 10; x > 0; x--) {
  y += x;
}

foreach

foreach statements are a shorthand for iterating over arrays

int y;
foreach (x in [1,2,3,4,5,6,7,8,9,10]) {
  y += x;
}
