Loops

For loop

THP loops are similar to PHP’s foreach. There is no equivalent to PHP’s for.

Braces are required.

Loop over values

val numbers = [0, 1, 2, 3]
╰╴No statement matched

for number in numbers {
  print(number)
}
thp

val dict = .{
╰╴No statement matched
  apple: 10,
  banana: 7,
  cherries: 3,
}

for value in dict {
  print("{value}")
}
thp

Loop over keys and values

val numbers = [0, 1, 2, 3]
╰╴No statement matched

for index, number in numbers {
  print("{index} : {number}")
}
thp

val dict = .{
╰╴No statement matched
  apple: 10,
  banana: 7,
  cherries: 3,
}

for key, value in dict {
  print("{key} => {value}")
}
thp

While loop

val colors = ["red", "green", "blue"]
╰╴No statement matched
var index = 0

while index < colors.size() {
  print("{colors[index]}")
  index += 1
}
thp

Labelled loops

TBD

You can give labels to loops, allowing you to break and continue in nested loops.

:top for i in values_1 {
╰╴No statement matched
  for j in values_2 {
      // ...
      break :top
  }
}
