$ is Nim's general way of spelling toString.

Example:

import system/dollars
assert $0.1 == "0.1"
assert $(-2*3) == "-6"

Imports

digitsutils, miscdollars

proc `$`(t: typedesc): string {.magic: "TypeTrait", ...raises: [], tags: [], forbids: [].}: Returns the name of the given type.

For more procedures dealing with typedesc, see typetraits module.

doAssert $(typeof(42)) == "int" doAssert $(typeof("Foo")) == "string" static: doAssert $(typeof(@['A', 'B'])) == "seq[char]"

proc `$`(x: bool): string {.magic: "BoolToStr", noSideEffect, ...raises: [], tags: [], forbids: [].}: The stringify operator for a boolean argument. Returns x converted to the string "false" or "true". Source Edit
proc `$`(x: char): string {.magic: "CharToStr", noSideEffect, ...raises: [], tags: [], forbids: [].}: The stringify operator for a character argument. Returns x converted to a string.

proc `$`(x: cstring): string {.magic: "CStrToStr", noSideEffect, ...raises: [], tags: [], forbids: [].}: The stringify operator for a CString argument. Returns x converted to a string. Source Edit
proc `$`(x: int): string {....raises: [], tags: [], forbids: [].}: Outplace version of addInt. Source Edit
proc `$`(x: int64): string {....raises: [], tags: [], forbids: [].}: Outplace version of addInt. Source Edit
proc `$`(x: string): string {.magic: "StrToStr", noSideEffect, ...raises: [], tags: [], forbids: [].}: The stringify operator for a string argument. Returns x as it is. This operator is useful for generic code, so that $expr also works if expr is already a string. Source Edit
proc `$`(x: uint64): string {....raises: [], tags: [], forbids: [].}: Outplace version of addInt. Source Edit
func `$`(x`gensym0: `{}`(int, lit)): string {.compileTime, ...raises: [], tags: [], forbids: [].}: Source Edit
func `$`(x`gensym1: `{}`(uint64, lit)): string {.compileTime, ...raises: [], tags: [], forbids: [].}: Source Edit
func `$`(x`gensym2: `{}`(int64, lit)): string {.compileTime, ...raises: [], tags: [], forbids: [].}: Source Edit
proc `$`[Enum: enum](x: Enum): string {.magic: "EnumToStr", noSideEffect, ...raises: [], tags: [], forbids: [].}: The stringify operator for an enumeration argument. This works for any enumeration type thanks to compiler magic.

If a $ operator for a concrete enumeration is provided, this is used instead. (In other words: Overwriting is possible.)

proc `$`[T, IDX](x: array[IDX, T]): string: Generic $ operator for arrays that is lifted from the components. Source Edit
proc `$`[T, U](x: HSlice[T, U]): string: Generic $ operator for slices that is lifted from the components of x. Example:

$(1 .. 5) == "1 .. 5"

proc `$`[T: tuple](x: T): string: Generic $ operator for tuples that is lifted from the components of x. Example:

$(23, 45) == "(23, 45)" $(a: 23, b: 45) == "(a: 23, b: 45)" $() == "()"
Source Edit
proc `$`[T](x: openArray[T]): string: Generic $ operator for openarrays that is lifted from the components of x. Example:

$(@[23, 45].toOpenArray(0, 1)) == "[23, 45]"
Source Edit
proc `$`[T](x: seq[T]): string: Generic $ operator for seqs that is lifted from the components of x. Example:

$(@[23, 45]) == "@[23, 45]"
Source Edit
proc `$`[T](x: set[T]): string: Generic $ operator for sets that is lifted from the components of x. Example:

${23, 45} == "{23, 45}"
