PrintLine v0.1.0
Writes a value to standard output, followed by a newline.
Package: Io
Signature
PrintLine mirrors every Print overload and adds a form that takes nothing and writes only the newline:
// Newline only
func PrintLine();
// Text
func PrintLine(value: String);
func PrintLine(value: Slice<char8>);
// Formatted
func PrintLine(format: Slice<char8>, args: Stringable...);
// Signed integers
func PrintLine(value: int8);
func PrintLine(value: int16);
func PrintLine(value: int32);
func PrintLine(value: int64);
func PrintLine(value: int);
// Unsigned integers
func PrintLine(value: uint8);
func PrintLine(value: uint16);
func PrintLine(value: uint32);
func PrintLine(value: uint64);
func PrintLine(value: uint);
// Floating-point
func PrintLine(value: float32);
func PrintLine(value: float64);
// Booleans
func PrintLine(value: bool8);
func PrintLine(value: bool16);
func PrintLine(value: bool32);
// Characters
func PrintLine(value: char8);
func PrintLine(value: char16);
func PrintLine(value: char32);
Parameters
| Name | Type | Description |
|---|---|---|
value | Any type above | The value to write. |
format | Slice<char8> | Format string; each {} takes the next argument. |
args | Stringable... | The values substituted into format, in order. |
bool is an alias for bool8, char for char32, and float for float64, so a call on an alias reaches the overload for the sized type it names.
Remarks
Each overload is its Print counterpart followed by a newline, and everything that page says about the text of a value, about {} substitution, and about a String argument staying yours to Free holds here unchanged.
The newline written is a single LF (\n), on every platform, including Windows. Nothing translates it to CRLF on the way out.
PrintLine() with no argument writes that newline by itself, which is how you leave a blank line.
Example
import Io::PrintLine;
func Main() -> int {
PrintLine("Report");
PrintLine(); // blank line
PrintLine("{} items, {} failed", 12, 0);
PrintLine(true); // true
PrintLine(1.0 / 3.0); // 0.333333333333333
return 0;
}
