Utpl implements C-style while loops which run as long as the condition
is fulfilled.
Like with for-loops, an alternative syntax form suitable for template
blocks is supported.
-- Expect stdout --
A simple counting while-loop:
Iteration 0
Iteration 1
Iteration 2
Iteration 3
Iteration 4
Iteration 5
Iteration 6
Iteration 7
Iteration 8
Iteration 9
If the loop body consists of only one statement, the curly braces
may be omitted:
Iteration 0
Iteration 1
Iteration 2
Iteration 3
Iteration 4
Iteration 5
Iteration 6
Iteration 7
Iteration 8
Iteration 9
A counting while-loop using the alternative syntax:
Iteration 0
Iteration 1
Iteration 2
Iteration 3
Iteration 4
Iteration 5
Iteration 6
Iteration 7
Iteration 8
Iteration 9
-- End --
-- Testcase --
A simple counting while-loop:
{%
i = 0;
while (i < 10) {
print("Iteration ");
print(i);
print("\n");
i++;
}
%}
If the loop body consists of only one statement, the curly braces
may be omitted:
{%
i = 0;
while (i < 10)
print("Iteration ", i++, "\n");
%}
A counting while-loop using the alternative syntax:
{% while (x < 10): -%}
Iteration {{ "" + x++ }}
{% endwhile %}
