Print

Writes a value to standard output, without a trailing newline.

Module: Std::Io

Signature

Print is overloaded for strings, raw buffers, format strings, and every built-in scalar type:

// Strings
func Print(string: char8[]);
func Print(string: char16[]);
func Print(string: String);

// Raw buffer
func Print(string: *const char8, length: uint);
func Print(string: *const char16, length: uint);

// Formatted (see Std::Format)
func Print(format: char8[], args: Display...);

// Scalars — one overload per built-in type
func Print(value: int);
func Print(value: int8);
func Print(value: int16);
func Print(value: int32);
func Print(value: int64);
func Print(value: uint);
func Print(value: uint8);
func Print(value: uint16);
func Print(value: uint32);
func Print(value: uint64);
func Print(value: float);
func Print(value: float32);
func Print(value: float64);
func Print(value: bool);
func Print(value: bool8);
func Print(value: bool16);
func Print(value: bool32);
func Print(value: char);
func Print(value: char8);
func Print(value: char16);
func Print(value: char32);

Parameters

Name	Type	Description
string	various	The text to write. UTF-8 (char8) or UTF-16 (char16).
length	uint	Number of code units to write from a raw pointer.
format	char8[]	Format string; each {} placeholder is replaced by an argument.
args	Display...	Values substituted into format, in order.
value	scalar	A numeric, boolean, or character value rendered via its ToString.

Description

Print writes its argument to standard output as-is, with no trailing newline. The scalar overloads format the value through its Display implementation, so Print(42) and Print(true) work directly. The format-string overload uses Format — use {} as the placeholder.

To write a line and move to the next one, use PrintLine.

Example

import Std::Io::*;

func Main() -> int {
    Print("Hello, ");
    Print("World!\n");

    Print("x = {}, y = {}\n", 3, 4);

    Print(42);
    Print('\n');
    return 0;
}
