_Added in gomplate [v2.7.0](https://github.com/hairyhenderson/gomplate/releases/tag/v2.7.0)_
### Usage

```
strings.Sort list
```
```
list | strings.Sort
```

### Arguments

| name | description |
|------|-------------|

[bar baz foo]
```

## `strings.SkipLines`_(unreleased)_
**Unreleased:** _This function is in development, and not yet available in released builds of gomplate._

Skips the given number of lines (each ending in a `\n`), returning the
remainder.

If `skip` is greater than the number of lines in `in`, an empty string is
returned.

### Usage

```
strings.SkipLines skip in
```
```
in | strings.SkipLines skip
```

### Arguments

| name | description |
|------|-------------|
| `skip` | _(required)_ the number of lines to skip - must be a positive number |
| `in` | _(required)_ the input string |

### Examples

```console
$ gomplate -i '{{ "foo\nbar\nbaz" | strings.SkipLines 2 }}'

```

## `strings.Split`

_Not to be confused with [`split`](#split), which is deprecated._

Slices `input` into the substrings separated by `separator`, returning a
slice of the substrings between those separators. If `input` does not
contain `separator` and `separator` is not empty, returns a single-element
slice whose only element is `input`.

If `separator` is empty, it will split after each UTF-8 sequence. If
both inputs are empty (i.e. `strings.Split "" ""`), it will return an
empty slice.

This is equivalent to [`strings.SplitN`](#strings-splitn) with a `count`
of `-1`.

Note that the delimiter is not included in the resulting elements.

_Added in gomplate [v1.9.0](https://github.com/hairyhenderson/gomplate/releases/tag/v1.9.0)_
### Usage

```
strings.Split separator input
```
```
input | strings.Split separator
```

### Arguments

| name | description |
|------|-------------|
| `separator` | _(required)_ the delimiter to split on, can be multiple characters |
| `input` | _(required)_ the input string |

### Examples

```console
$ gomplate -i '{{range ("Bart,Lisa,Maggie" | strings.Split ",") }}Hello, {{.}}
{{end}}'
Hello, Bart
Hello, Lisa
Hello, Maggie
```
```console
$ gomplate -i '{{range strings.Split "," "One,Two,Three" }}{{.}}{{"\n"}}{{end}}'
One
Two
Three
```

## `strings.SplitN`

_Not to be confused with [`splitN`](#splitn), which is deprecated._

Slices `input` into the substrings separated by `separator`, returning a
slice of the substrings between those separators. If `input` does not
contain `separator` and `separator` is not empty, returns a single-element
slice whose only element is `input`.

The `count` determines the number of substrings to return:

* `count > 0`: at most `count` substrings; the last substring will be the
  unsplit remainder.
* `count == 0`: the result is nil (zero substrings)
* `count < 0`: all substrings

See [`strings.Split`](#strings-split) for more details.

_Added in gomplate [v1.9.0](https://github.com/hairyhenderson/gomplate/releases/tag/v1.9.0)_
### Usage

|------|-------------|
| `separator` | _(required)_ the delimiter to split on, can be multiple characters |
| `count` | _(required)_ the maximum number of substrings to return |
| `input` | _(required)_ the input string |

### Examples

```console
$ gomplate -i '{{ range ("foo:bar:baz" | strings.SplitN ":" 2) }}{{.}}
{{end}}'
foo
bar:baz
```

**Alias:** `quote`

Surrounds an input string with double-quote characters (`"`). If the input is not a string, converts first.

`"` characters in the input are first escaped with a `\` character.

This is a convenience function which is equivalent to:

```

## `strings.Repeat`

Returns a new string consisting of `count` copies of the input string.

It errors if `count` is negative or if the length of `input` multiplied by `count` overflows.

This wraps Go's [`strings.Repeat`](https://golang.org/pkg/strings/#Repeat).

172-21-1-42
```

## `strings.Slug`

```

## `strings.WordWrap`

Inserts new line breaks into the input string so it ends up with lines that are at most `width` characters wide.

The line-breaking algorithm is _naïve_ and _greedy_: lines are only broken between words (i.e. on whitespace characters), and no effort is made to "smooth" the line endings.

When words that are longer than the desired width are encountered (e.g. long URLs), they are not broken up. Correctness is valued above line length.

The line-break sequence defaults to `\n` (i.e. the LF/Line Feed character), regardless of OS.

_Added in gomplate [v3.3.0](https://github.com/hairyhenderson/gomplate/releases/tag/v3.3.0)_
### Usage

```
strings.WordWrap [width] [lbseq] in
```
```
in | strings.WordWrap [width] [lbseq]
```

### Arguments

| name | description |
|------|-------------|
| `width` | _(optional)_ The desired maximum line length (number of characters - defaults to `80`) |
| `lbseq` | _(optional)_ The line-break sequence to use (defaults to `\n`) |
| `in` | _(required)_ The input |

### Examples

```console
$ gomplate -i '{{ "Hello, World!" | strings.WordWrap 7 }}'
Hello,
World!
```
```console
$ gomplate -i '{{ strings.WordWrap 20 "\\\n" "a string with a long url http://example.com/a/very/long/url which should not be broken" }}'
a string with a long
url
http://example.com/a/very/long/url
which should not be
broken
```

## `strings.RuneCount`

Return the number of _runes_ (Unicode code-points) contained within the
input. This is similar to the built-in `len` function, but `len` counts
the length in _bytes_. The length of an input containing multi-byte
code-points should therefore be measured with `strings.RuneCount`.

Inputs will first be converted to strings, and multiple inputs are
concatenated.

This wraps Go's [`utf8.RuneCountInString`](https://golang.org/pkg/unicode/utf8/#RuneCountInString)
function.

_Added in gomplate [v3.4.0](https://github.com/hairyhenderson/gomplate/releases/tag/v3.4.0)_
