Syntax

The syntax for while loops is:

f++:   
while{options}(condition)
{
	//loop code-block
}

n++:   
@while{options}(condition)
{
	//loop code-block
}

Note: Single-line code blocks do not need to be enclosed in parentheses.

Description

The while function takes a single parameter specifying a loop condition, then loops through the code-block following the call while the loop condition does not evaluate to 0 (for while loops the loop condition is evaluated before each iteration of the loop code-block).

Note: f++ is used for while conditions, even for n++. If you accidentally use n++ for the condition it will most often run without any syntax or semantic errors anyway.

Note: If not writing to the output file Nift will skip to the first non-whitespace (ie. to the first character that is not a space, tab or newline) after a while loop and inject it to the output file where the call started. If you want to prevent Nift from doing this put a '!' after the loop, eg.: 

@while{!o}(condition)
{
	# block
}!

Options

The following options are available for while loops:

option description
f++ parse while loop code-block with f++
n++ parse while loop code-block with n++
!o do not add output
s add scope
!s do not add scope
!\n do not add newline between each loop iteration
\n add double newline between each loop iteration
eob="value" add value between each loop iteration

f++ example

Examples of while being used with f++: 

int i=0
while(i < 10)
	console("i: `i+=1`")

int i=0
while{!s, !o}(i+=1; i<10)
	console("i: ", i)

n++ example

Examples of while being used with n++: 

@int i=0
@while{\n}(i < 10)
	i:  @++(i)

@int i=0
@while{f++, !o, !s}(i+=1; i < 10)
{
	//f++ code for scripting
}
