Reads the next token as a whole number of type T (int by default). Only space and tab are skipped
in front of it unless you pass spaces.
parse_int :: (
line: *string,
$T: Type = int,
spaces := " \t",
delimiters := DEFAULT_DELIMITERS
) -> (value: T, success: bool)The second result is false when the token is not entirely a number, or there is none, or the
number does not fit T (including a minus sign for an unsigned T). The value is then 0.
Parameters
- line: *string
- $T: Type
- spaces := " \t"
- delimiters := DEFAULT_DELIMITERS
Returns
- value: T
- success: bool
line := " 42;7";
value, ok := parse_int(*line);
assert(ok && value == 42);
big := "257";
small, small_ok := parse_int(*big, u8);
assert(!small_ok && small == 0);
