String formatting (sprintf-style). Uses C printf format specifiers (%d, %s, etc.).

Buffer-Based (write to existing buffer)

Function	Signature	Description
sprintf_i	(buf: str, size: usize, fmt: str, a: i64) -> i32	Format integer into buffer.
sprintf_s	(buf: str, size: usize, fmt: str, s: str) -> i32	Format string into buffer.
sprintf_ii	(buf, size, fmt, a: i64, b: i64) -> i32	Format two integers.
sprintf_si	(buf, size, fmt, s: str, a: i64) -> i32	Format string and integer.
sprintf_ss	(buf, size, fmt, a: str, b: str) -> i32	Format two strings.

Allocating (returns new string)

Function	Signature	Description
alloc_i	(fmt: str, a: i64) -> str	Format integer, allocate result.
alloc_s	(fmt: str, s: str) -> str	Format string, allocate result.
alloc_si	(fmt: str, s: str, a: i64) -> str	Format string and integer.

craft main() -> void {
    make s: str = fmt.alloc_i("%d", 42);
    print(s);
