std.fmt

formatInt function

pub fn formatInt(value: int, spec: string): string

stdlib/std/fmt.lyr:20

formatUint function

pub fn formatUint(value: uint, spec: string): string

stdlib/std/fmt.lyr:21

formatFloat function

pub fn formatFloat(value: float, spec: string): string

stdlib/std/fmt.lyr:22

formatBool function

pub fn formatBool(value: bool, spec: string): string

stdlib/std/fmt.lyr:23

formatChar function

pub fn formatChar(value: char, spec: string): string

stdlib/std/fmt.lyr:24

formatString function

pub fn formatString(value: string, spec: string): string

stdlib/std/fmt.lyr:28

formatRadix function

pub fn formatRadix(value: int, radix: int): string

To a base from 2 to 36. Letters from a for digit values above 9.

The inverse of std.string.parseIntRadix. They live in different modules because parsing is text processing and formatting is output, and std.string must not import std.fmt.

stdlib/std/fmt.lyr:43

formatHex function

pub fn formatHex(value: int): string

stdlib/std/fmt.lyr:77

formatBinary function

pub fn formatBinary(value: int): string

stdlib/std/fmt.lyr:81

formatOctal function

pub fn formatOctal(value: int): string

stdlib/std/fmt.lyr:85

formatHexPadded function

pub fn formatHexPadded(value: int, width: int): string

Hexadecimal with a fixed number of digits and leading zeros: formatHexPadded(255, 4) is "00ff", for addresses and colour values where the width carries meaning.

stdlib/std/fmt.lyr:91

padLeft function

pub fn padLeft(value: string, width: int): string

stdlib/std/fmt.lyr:97

padRight function

pub fn padRight(value: string, width: int): string

stdlib/std/fmt.lyr:101

center function

pub fn center(value: string, width: int): string

Centres. On an odd remainder the extra character goes to the RIGHT. A decision rather than a matter of course, but without it the same input yields two different results depending on the implementation.

stdlib/std/fmt.lyr:108

formatBytes function

pub fn formatBytes(bytes: int): string

Bytes in readable form: 1536 becomes "1.5 KB".

Base 1024 with the prefixes without i (KB rather than KiB), the spelling operating systems and tools actually use.

stdlib/std/fmt.lyr:123

table function

pub fn table(rows: string[][], separator: string): string

Aligns columns. Each row is a string[]; short rows are padded with empty cells.

No borders and no header handling: what a table means is the caller's business. This does the tedious part — two passes over the data, to know the column widths before printing.
