- coalesce: Given a list of items, return the first non-empty one.
This follows the same rules as 'empty'. `{{ coalesce .someVal 0 "hello" }}`
will return `.someVal` if set, or else return "hello". The 0 is skipped
because it is an empty value.

### Lists Functions:
These are used to manipulate lists: `{{ list 1 2 3 | reverse | first }}`
- first: Get the first item in a 'list'. 'list 1 2 3 | first' prints '1'
- last: Get the last item in a 'list': 'list 1 2 3 | last ' prints '3'
- rest: Get all but the first item in a list: 'list 1 2 3 | rest' returns '[2 3]'
- initial: Get all but the last item in a list: 'list 1 2 3 | initial' returns '[1 2]'
- append: Add an item to the end of a list: 'append $list 4' adds '4' to the end of '$list'
- prepend: Add an item to the beginning of a list: 'prepend $list 4' puts 4 at the beginning of the list.
- reverse: Reverse the items in a list.
- uniq: Remove duplicates from a list.
- without: Return a list with the given values removed: 'without (list 1 2 3) 1' would return '[2 3]'
- has: Return 'tru' if the item is found in the list: 'has "foo" $list' will return 'true' if the list contains "foo"
### Dict Functions:
These are used to manipulate dicts.

the dict. `set $dict $key $value`. For convenience, it returns the dict,

### Cryptographic Functions:
- derivePassword: Derive a password from the given parameters according to the "Master Password" algorithm (http://masterpasswordapp.com/algorithm.html)
Given parameters (in order) are:
`counter` (starting with 1), `password_type` (maximum, long, medium, short, basic, or pin), `password`,
`user`, and `site`. The following line generates a long password for the user "user" and with a master-password "password" on the site "example.com":
```
{{ derivePassword 1 "long" "password" "user" "example.com" }}
```
## SemVer Functions:
These functions provide version parsing and comparisons for SemVer 2 version
strings.
- semver: Parse a semantic version and return a Version object.
- semverCompare: Compare a SemVer range to a particular version.

/*
Sprig: Template functions for Go.
This package contains a number of utility functions for working with data
inside of Go `html/template` and `text/template` files.
To add these functions, use the `template.Funcs()` method:
t := templates.New("foo").Funcs(sprig.FuncMap())
Note that you should add the function map before you parse any template files.
In several cases, Sprig reverses the order of arguments from the way they
appear in the standard library. This is to make it easier to pipe
arguments into functions.
Date Functions
- date FORMAT TIME: Format a date, where a date is an integer type or a time.Time type, and
format is a time.Format formatting string.
- dateModify: Given a date, modify it with a duration: `date_modify "-1.5h" now`. If the duration doesn't
parse, it returns the time unaltered. See `time.ParseDuration` for info on duration strings.
- now: Current time.Time, for feeding into date-related functions.
- htmlDate TIME: Format a date for use in the value field of an HTML "date" form element.
- dateInZone FORMAT TIME TZ: Like date, but takes three arguments: format, timestamp,
timezone.
- htmlDateInZone TIME TZ: Like htmlDate, but takes two arguments: timestamp,
timezone.
String Functions
- abbrev: Truncate a string with ellipses. `abbrev 5 "hello world"` yields "he..."
- abbrevboth: Abbreviate from both sides, yielding "...lo wo..."
- trunc: Truncate a string (no suffix). `trunc 5 "Hello World"` yields "hello".
- trim: strings.TrimSpace
- trimAll: strings.Trim, but with the argument order reversed `trimAll "$" "$5.00"` or `"$5.00 | trimAll "$"`
- trimSuffix: strings.TrimSuffix, but with the argument order reversed: `trimSuffix "-" "ends-with-"`
- trimPrefix: strings.TrimPrefix, but with the argument order reversed `trimPrefix "$" "$5"`
- upper: strings.ToUpper
- lower: strings.ToLower
- nospace: Remove all space characters from a string. `nospace "h e l l o"` becomes "hello"
- title: strings.Title
- untitle: Remove title casing
- repeat: strings.Repeat, but with the arguments switched: `repeat count str`. (This simplifies common pipelines)
- substr: Given string, start, and length, return a substr.
- initials: Given a multi-word string, return the initials. `initials "Matt Butcher"` returns "MB"
- randAlphaNum: Given a length, generate a random alphanumeric sequence
- randAlpha: Given a length, generate an alphabetic string
- randAscii: Given a length, generate a random ASCII string (symbols included)
- randNumeric: Given a length, generate a string of digits.
- wrap: Force a line wrap at the given width. `wrap 80 "imagine a longer string"`
- wrapWith: Wrap a line at the given length, but using 'sep' instead of a newline. `wrapWith 50, "<br>", $html`
- contains: strings.Contains, but with the arguments switched: `contains substr str`. (This simplifies common pipelines)
- hasPrefix: strings.hasPrefix, but with the arguments switched
- hasSuffix: strings.hasSuffix, but with the arguments switched
- quote: Wrap string(s) in double quotation marks, escape the contents by adding '\' before '"'.
- squote: Wrap string(s) in double quotation marks, does not escape content.
- cat: Concatenate strings, separating them by spaces. `cat $a $b $c`.
- indent: Indent a string using space characters. `indent 4 "foo\nbar"` produces " foo\n bar"
- replace: Replace an old with a new in a string: `$name | replace " " "-"`
- plural: Choose singular or plural based on length: `len $fish | plural "one anchovy" "many anchovies"`
- sha256sum: Generate a hex encoded sha256 hash of the input
- toString: Convert something to a string
String Slice Functions:
- join: strings.Join, but as `join SEP SLICE`
- split: strings.Split, but as `split SEP STRING`. The results are returned
as a map with the indexes set to _N, where N is an integer starting from 0.
Use it like this: `{{$v := "foo/bar/baz" | split "/"}}{{$v._0}}` (Prints `foo`)
- splitList: strings.Split, but as `split SEP STRING`. The results are returned
as an array.
- toStrings: convert a list to a list of strings. 'list 1 2 3 | toStrings' produces '["1" "2" "3"]'
- sortAlpha: sort a list lexicographically.
Integer Slice Functions:
- until: Given an integer, returns a slice of counting integers from 0 to one
less than the given integer: `range $i, $e := until 5`
- untilStep: Given start, stop, and step, return an integer slice starting at
'start', stopping at `stop`, and incrementing by 'step. This is the same
as Python's long-form of 'range'.
Conversions:
- atoi: Convert a string to an integer. 0 if the integer could not be parsed.
- in64: Convert a string or another numeric type to an int64.
- int: Convert a string or another numeric type to an int.
- float64: Convert a string or another numeric type to a float64.
Defaults:
- default: Give a default value. Used like this: trim " "| default "empty".
Since trim produces an empty string, the default value is returned. For
things with a length (strings, slices, maps), len(0) will trigger the default.
For numbers, the value 0 will trigger the default. For booleans, false will
trigger the default. For structs, the default is never returned (there is
no clear empty condition). For everything else, nil value triggers a default.
- empty: Return true if the given value is the zero value for its type.
Caveats: structs are always non-empty. This should match the behavior of
{{if pipeline}}, but can be used inside of a pipeline.
- coalesce: Given a list of items, return the first non-empty one.
This follows the same rules as 'empty'. '{{ coalesce .someVal 0 "hello" }}`
will return `.someVal` if set, or else return "hello". The 0 is skipped
because it is an empty value.
- compact: Return a copy of a list with all of the empty values removed.
'list 0 1 2 "" | compact' will return '[1 2]'
OS:
- env: Resolve an environment variable
- expandenv: Expand a string through the environment
File Paths:
- base: Return the last element of a path. https://golang.org/pkg/path#Base
- dir: Remove the last element of a path. https://golang.org/pkg/path#Dir
- clean: Clean a path to the shortest equivalent name. (e.g. remove "foo/.."
from "foo/../bar.html") https://golang.org/pkg/path#Clean
- ext: https://golang.org/pkg/path#Ext
- isAbs: https://golang.org/pkg/path#IsAbs
Encoding:
- b64enc: Base 64 encode a string.
- b64dec: Base 64 decode a string.
Reflection:
- typeOf: Takes an interface and returns a string representation of the type.
For pointers, this will return a type prefixed with an asterisk(`*`). So
a pointer to type `Foo` will be `*Foo`.
- typeIs: Compares an interface with a string name, and returns true if they match.
Note that a pointer will not match a reference. For example `*Foo` will not
match `Foo`.
- typeIsLike: Compares an interface with a string name and returns true if
the interface is that `name` or that `*name`. In other words, if the given
value matches the given type or is a pointer to the given type, this returns
true.
- kindOf: Takes an interface and returns a string representation of its kind.
- kindIs: Returns true if the given string matches the kind of the given interface.
Note: None of these can test whether or not something implements a given
interface, since doing so would require compiling the interface in ahead of
time.
Data Structures:
- tuple: Takes an arbitrary list of items and returns a slice of items. Its
tuple-ish properties are mainly gained through the template idiom, and not
through an API provided here. WARNING: The implementation of tuple will
change in the future.
- list: An arbitrary ordered list of items. (This is prefered over tuple.)
- dict: Takes a list of name/values and returns a map[string]interface{}.
The first parameter is converted to a string and stored as a key, the
second parameter is treated as the value. And so on, with odds as keys and
evens as values. If the function call ends with an odd, the last key will
be assigned the empty string. Non-string keys are converted to strings as
follows: []byte are converted, fmt.Stringers will have String() called.
errors will have Error() called. All others will be passed through
fmt.Sprtinf("%v").
Lists Functions:
These are used to manipulate lists: '{{ list 1 2 3 | reverse | first }}'
- first: Get the first item in a 'list'. 'list 1 2 3 | first' prints '1'
- last: Get the last item in a 'list': 'list 1 2 3 | last ' prints '3'
- rest: Get all but the first item in a list: 'list 1 2 3 | rest' returns '[2 3]'
- initial: Get all but the last item in a list: 'list 1 2 3 | initial' returns '[1 2]'
- append: Add an item to the end of a list: 'append $list 4' adds '4' to the end of '$list'
- prepend: Add an item to the beginning of a list: 'prepend $list 4' puts 4 at the beginning of the list.
- reverse: Reverse the items in a list.
- uniq: Remove duplicates from a list.
- without: Return a list with the given values removed: 'without (list 1 2 3) 1' would return '[2 3]'
- has: Return 'true' if the item is found in the list: 'has "foo" $list' will return 'true' if the list contains "foo"
Dict Functions:
These are used to manipulate dicts.
- set: Takes a dict, a key, and a value, and sets that key/value pair in
the dict. `set $dict $key $value`. For convenience, it returns the dict,
even though the dict was modified in place.
- unset: Takes a dict and a key, and deletes that key/value pair from the
dict. `unset $dict $key`. This returns the dict for convenience.
- hasKey: Takes a dict and a key, and returns boolean true if the key is in
the dict.
- pluck: Given a key and one or more maps, get all of the values for that key.
- keys: Get an array of all of the keys in a dict.
- pick: Select just the given keys out of the dict, and return a new dict.
- omit: Return a dict without the given keys.
Math Functions:
Integer functions will convert integers of any width to `int64`. If a
string is passed in, functions will attempt to convert with
`strconv.ParseInt(s, 1064)`. If this fails, the value will be treated as 0.
- add1: Increment an integer by 1
- add: Sum an arbitrary number of integers
- sub: Subtract the second integer from the first
- div: Divide the first integer by the second
- mod: Module of first integer divided by second
- mul: Multiply integers
- max: Return the biggest of a series of one or more integers
- min: Return the smallest of a series of one or more integers
- biggest: DEPRECATED. Return the biggest of a series of one or more integers
Crypto Functions:
- genPrivateKey: Generate a private key for the given cryptosystem. If no
argument is supplied, by default it will generate a private key using
the RSA algorithm. Accepted values are `rsa`, `dsa`, and `ecdsa`.
- derivePassword: Derive a password from the given parameters according to the ["Master Password" algorithm](http://masterpasswordapp.com/algorithm.html)
Given parameters (in order) are:
`counter` (starting with 1), `password_type` (maximum, long, medium, short, basic, or pin), `password`,
`user`, and `site`
SemVer Functions:
These functions provide version parsing and comparisons for SemVer 2 version
strings.
- semver: Parse a semantic version and return a Version object.
- semverCompare: Compare a SemVer range to a particular version.

# Type Conversion Functions
The following type conversion functions are provided by Sprig:
- `atoi`: Convert a string to an integer
- `float64`: Convert to a float64
- `int`: Convert to an `int` at the system's width.
- `int64`: Convert to an `int64`
- `toString`: Convert to a string
- `toStrings`: Convert a list, slice, or array to a list of strings.
Only `atoi` requires that the input be a specific type. The others will attempt
to convert from any type to the destination type. For example, `int64` can convert
floats to ints, and it can also convert strings to ints.
## toStrings
Given a list-like collection, produce a slice of strings.
```
list 1 2 3 | toStrings
```
The above converts `1` to `"1"`, `2` to `"2"`, and so on, and then returns
them as a list.

# Cryptographic and Security Functions
Sprig provides a couple of advanced cryptographic functions.
## sha256sum
The `sha256sum` function receives a string, and computes it's SHA256 digest.
```
sha256sum "Hello world!"
```
The above will compute the SHA 256 sum in an "ASCII armored" format that is
safe to print.
## derivePassword
The `derivePassword` function can be used to derive a specific password based on
some shared "master password" constraints. The algorithm for this is
[well specified](http://masterpasswordapp.com/algorithm.html).
```
derivePassword 1 "long" "password" "user" "example.com"
```
Note that it is considered insecure to store the parts directly in the template.
## generatePrivateKey
The `generatePrivateKey` function generates a new private key encoded into a PEM
block.
It takes one of the values for its first param:
- `ecdsa`: Generate an elyptical curve DSA key (P256)
- `dsa`: Generate a DSA key (L2048N256)
- `rsa`: Generate an RSA 4096 key

# Date Functions
## now
The current date/time. Use this in conjunction with other date functions.
## date
The `date` function formats a date.
Format the date to YEAR-MONTH-DAY:
```
now | date "2006-01-02"
```
Date formatting in Go is a [little bit different](https://pauladamsmith.com/blog/2011/05/go_time.html).
In short, take this as the base date:
```
Mon Jan 2 15:04:05 MST 2006
```
Write it in the format you want. Above, `2006-01-02` is the same date, but
in the format we want.
## dateInZone
Same as `date`, but with a timezone.
```
date "2006-01-02" (now) "UTC"
```
## dateModify
The `dateModify` takes a modification and a date and returns the timestamp.
Subtract an hour and thirty minutes from the current time:
```
now | date_modify "-1.5h"
```
## htmlDate
The `htmlDate` function formates a date for inserting into an HTML date picker
input field.
```
now | htmlDate
```
## htmlDateInZone
Same as htmlDate, but with a timezone.
```
htmlDate (now) "UTC"
```

# Default Functions
Sprig provides tools for setting default values for templates.
## default
To set a simple default value, use `default`:
```
default "foo" .Bar
```
In the above, if `.Bar` evaluates to a non-empty value, it will be used. But if
it is empty, `foo` will be returned instead.
The definition of "empty" depends on type:
- Numeric: 0
- String: ""
- Lists: `[]`
- Dicts: `{}`
- Boolean: `false`
- And always `nil` (aka null)
For structs, there is no definition of empty, so a struct will never return the
default.
## empty
The `empty` function returns `true` if the given value is considered empty, and
`false` otherwise. The empty values are listed in the `default` section.
```
empty .Foo
```
Note that in Go template conditionals, emptiness is calculated for you. Thus,
you rarely need `if empty .Foo`. Instead, just use `if .Foo`.
## coalesce
The `coalesce` function takes a list of values and returns the first non-empty
one.
```
coalesce 0 1 2
```
The above returns `1`.
This function is useful for scanning through multiple variables or values:
```
coalesce .name .parent.name "Matt"
```
The above will first check to see if `.name` is empty. If it is not, it will return
that value. If it _is_ empty, `coalesce` will evaluate `.parent.name` for emptiness.
Finally, if both `.name` and `.parent.name` are empty, it will return `Matt`.

# Dictionaries and Dict Functions
Sprig provides a key/value storage type called a `dict` (short for "dictionary",
as in Python). A `dict` is an _unorder_ type.
The key to a dictionary **must be a string**. However, the value can be any
type, even another `dict` or `list`.
Unlike `list`s, `dict`s are not immutable. The `set` and `unset` functions will
modify the contents of a dictionary.
## dict
Creating dictionaries is done by calling the `dict` function and passing it a
list of pairs.
The following creates a dictionary with three items:
```
$myDict := dict "name1" "value1" "name2" "value2" "name3" "value 3"
```
## set
Use `set` to add a new key/value pair to a dictionary.
```
$_ := set $myDict "name4" "value4"
```
Note that `set` _returns the dictionary_ (a requirement of Go template functions),
so you may need to trap the value as done above with the `$_` assignment.
## unset
Given a map and a key, delete the key from the map.
```
$_ := unset $myDict "name4"
```
As with `set`, this returns the dictionary.
Note that if the key is not found, this operation will simply return. No error
will be generated.
## hasKey
The `hasKey` function returns `true` if the given dict contains the given key.
```
hasKey $myDict "name1"
```
If the key is not found, this returns `false`.
## pluck
The `pluck` function makes it possible to give one key and multiple maps, and
get a list of all of the matches:
```
pluck "name1" $myDict $myOtherDict
```
The above will return a `list` containing every found value (`[value1 otherValue1]`).
If the give key is _not found_ in a map, that map will not have an item in the
list (and the length of the returned list will be less than the number of dicts
in the call to `pluck`.
If the key is _found_ but the value is an empty value, that value will be
inserted.
A common idiom in Sprig templates is to uses `pluck... | first` to get the first
matching key out of a collection of dictionaries.
## keys
The `keys` function will return a `list` of all of the keys in a `dict`. Since
a dictionary is _unordered_, the keys will not be in a predictable order. They
can be sorted with `sortAlpha`.
```
keys $myDict | sortAlpha
```
## pick
The `pick` function selects just the given keys out of a dictionary, creating a
new `dict`.
```
$new := pick $myDict "name1" "name3"
```
The above returns `{name1: value1, name2: value2}`
## omit
The `omit` function is similar to `pick`, except it returns a new `dict` with all
the keys that _do not_ match the given keys.
```
$new := omit $myDict "name1" "name3"
```
The above returns `{name2: value2}`
## A Note on Dict Internals
A `dict` is implemented in Go as a `map[string]interface{}`. Go developers can
pass `map[string]interface{}` values into the context to make them available
to templates as `dict`s.

# Integer Slice Functions
## until
The `until` function builds a range of integers.

until 5
```
The above generates the list `[0, 1, 2, 3, 4]`.
This is useful for looping with `range $i, $e := until 5`.
## untilStep
Like `until`, `untilStep` generates a list of counting integers. But it allows
you to define a start, stop, and step:
```
untilStep 3 6 2
```
The above will produce `[3 5]` by starting with 3, and adding 2 until it is equal
or greater than 6. This is similar to Python's `range` function.

# Lists and List Functions
Sprig provides a simple `list` type that can contain arbitrary sequential lists
of data. This is similar to arrays or slices, but lists are designed to be used
as immutable data types.
Create a list of integers:
```
$myList := list 1 2 3 4 5
```
The above creates a list of `[1 2 3 4 5]`.
## first
To get the head item on a list, use `first`.
`first $myList` returns `1`
## rest
To get the tail of the list (everything but the first item), use `rest`.
`rest $myList` returns `[2 3 4 5]`
## last
To get the last item on a list, use `last`:
`last $myList` returns `5`. This is roughly analogous to reversing a list and
then calling `first`.
## initial
This compliments `last` by returning all _but_ the last element.
`initial $myList` returns `[1 2 3 4]`.
## append
Append a new item to an existing list, creating a new list.
```
$new = append $myList 6
```
The above would set `$new` to `[1 2 3 4 5 6]`. `$myList` would remain unaltered.
## prepend
Push an alement onto the front of a list, creating a new list.
```
prepend $myList 0
```
The above would produce `[0 1 2 3 4 5]`. `$myList` would remain unaltered.
## reverse
Produce a new list with the reversed elements of the given list.
```
reverse $myList
```
The above would generate the list `[5 4 3 2 1]`.
## uniq
Generate a list with all of the duplicates removed.
```
list 1 1 1 2 | uniq
```
The above would produce `[1 2]`
## without
The `without` function filters items out of a list.
```
without $myList 3
```
The above would produce `[1 2 4 5]`
Without can take more than one filter:
```
without $myList 1 3 5
```
That would produce `[2 4]`
## has
Test to see if a list has a particular element.
```
has $myList 4
```
The above would return `true`, while `has $myList "hello"` would return false.
## A Note on List Internals
A list is implemented in Go as a `[]interface{}`. For Go developers embedding
Sprig, you may pass `[]interface{}` items into your template context and be
able to use all of the `list` functions on those items.

# File Path Functions
While Sprig does not grant access to the filesystem, it does provide functions
for working with strings that follow file path conventions.
# base
Return the last element of a path.
```
base "foo/bar/baz"

The above prints "baz"
# dir
Return the directory, stripping the last part of the path. So `dir "foo/bar/baz"`
returns `foo/bar`
# clean
Clean up a path.
```
clean "foo/bar/../baz"
```
The above resolves the `..` and returns `foo/baz`
# ext

# Reflection Functions
Sprig provides rudimentary reflection tools. These help advanced template
developers understand the underlying Go type information for a particular value.
Go has several primitive _kinds_, like `string`, `slice`, `int64`, and `bool`.
Go has an open _type_ system that allows developers to create their own types.
Sprig provides a set of functions for each.
## Kind Functions
There are two Kind functions: `kindOf` returns the kind of an object.
```
kindOf "hello"
```
The above would return `string`. For simple tests (like in `if` blocks), the
`isKind` function will let you verify that a value is a particular kind:
```
kindIs "int" 123
```
The above will return `true`
## Type Functions
Types are slightly harder to work with, so there are three different functions:
- `typeOf` returns the underlying type of a value: `typeOf $foo`
- `typeIs` is like `kindIs`, but for types: `typeIs "*io.Buffer" $myVal`
- `typeIsLike` works as `kindIs`, except that it also dereferences pointers.
**Note:** None of these can test whether or not something implements a given
interface, since doing so would require compiling the interface in ahead of time.

# Semantic Version Functions
Some version schemes are easily parseable and comparable. Sprig provides functions
for working with [SemVer 2](http://semver.org) versions.
## semver
The `semver` function parses a string into a Semantic Version:
```
$version := semver "1.2.3-alpha.1+123"
```
_If the parser fails, it will cause template execution to halt with an error._
At this point, `$version` is a pointer to a `Version` object with the following
properties:
- `$version.Major`: The major number (`1` above)
- `$version.Minor`: The minor number (`2` above)
- `$version.Patch`: The patch number (`3` above)
- `$version.Prerelease`: The prerelease (`alpha.1` above)
- `$version.Metadata`: The build metadata (`123` above)
- `$version.Original`: The original version as a string
Additionally, you can compare a `Version` to another `version` using the `Compare`
function:
```
semver "1.4.3" | (semver "1.2.3").Compare
```
The above will return `-1`.
The return values are:
- `-1` if the given semver is greater than the semver whose `Compare` method was called
- `1` if the version who's `Compare` function was called is greater.
- `0` if they are the same version
(Note that in SemVer, the `Metadata` field is not compared during version
comparison operations.)
## semverCompare
A more robust comparison function is provided as `semverCompare`. This version
supports version ranges:
- `semverCompare "1.2.3" "1.2.3"` checks for an exact match
- `semverCompare "^1.2.0" "1.2.3"` checks that the major and minor versions match, and that the patch
number of the second version is _greater than or equal to_ the first parameter.
The SemVer functions use the [Masterminds semver library](https://github.com/Masterminds/semver),
from the creators of Sprig.
## Basic Comparisons
There are two elements to the comparisons. First, a comparison string is a list
of comma separated and comparisons. These are then separated by || separated or
comparisons. For example, `">= 1.2, < 3.0.0 || >= 4.2.3"` is looking for a
comparison that's greater than or equal to 1.2 and less than 3.0.0 or is
greater than or equal to 4.2.3.
The basic comparisons are:
* `=`: equal (aliased to no operator)
* `!=`: not equal
* `>`: greater than
* `<`: less than
* `>=`: greater than or equal to
* `<=`: less than or equal to
_Note, according to the Semantic Version specification pre-releases may not be
API compliant with their release counterpart. It says,_
> _A pre-release version indicates that the version is unstable and might not satisfy the intended compatibility requirements as denoted by its associated normal version._
_SemVer comparisons without a pre-release value will skip pre-release versions.
For example, `>1.2.3` will skip pre-releases when looking at a list of values
while `>1.2.3-alpha.1` will evaluate pre-releases._
## Hyphen Range Comparisons
There are multiple methods to handle ranges and the first is hyphens ranges.
These look like:
* `1.2 - 1.4.5` which is equivalent to `>= 1.2, <= 1.4.5`
* `2.3.4 - 4.5` which is equivalent to `>= 2.3.4, <= 4.5`
## Wildcards In Comparisons
The `x`, `X`, and `*` characters can be used as a wildcard character. This works
for all comparison operators. When used on the `=` operator it falls
back to the pack level comparison (see tilde below). For example,
* `1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
* `>= 1.2.x` is equivalent to `>= 1.2.0`
* `<= 2.x` is equivalent to `<= 3`
* `*` is equivalent to `>= 0.0.0`
## Tilde Range Comparisons (Patch)
The tilde (`~`) comparison operator is for patch level ranges when a minor
version is specified and major level changes when the minor number is missing.
For example,
* `~1.2.3` is equivalent to `>= 1.2.3, < 1.3.0`
* `~1` is equivalent to `>= 1, < 2`
* `~2.3` is equivalent to `>= 2.3, < 2.4`
* `~1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
* `~1.x` is equivalent to `>= 1, < 2`
## Caret Range Comparisons (Major)
The caret (`^`) comparison operator is for major level changes. This is useful
when comparisons of API versions as a major change is API breaking. For example,
* `^1.2.3` is equivalent to `>= 1.2.3, < 2.0.0`
* `^1.2.x` is equivalent to `>= 1.2.0, < 2.0.0`
* `^2.3` is equivalent to `>= 2.3, < 3`
* `^2.x` is equivalent to `>= 2.0.0, < 3`

# String Slice Functions
These function operate on or generate slices of strings. In Go, a slice is a
growable array. In Sprig, it's a special case of a `list`.
## join
Join a list of strings into a single string, with the given separator.
```
list "hello" "world" | join "_"
```
The above will produce `hello_world`
`join` will try to convert non-strings to a string value:
```
list 1 2 3 | join "+"
```
The above will produce `1+2+3`
## splitList and split
Split a string into a list of strings:
```
splitList "$" "foo$bar$baz"
```
The above will return `[foo bar baz]`
The older `split` function splits a string into a `dict`. It is designed to make
it easy to use template dot notation for accessing members:
```
$a := split "$" "foo$bar$baz"
```
The above produces a map with index keys. `{_0: foo, _1: bar, _2: baz}`
```
$a._0
```
The above produces `foo`
## sortAlpha
The `sortAlpha` function sorts a list of strings into alphabetical (lexicographical)
order.
It does _not_ sort in place, but returns a sorted copy of the list, in keeping
with the immutability of lists.

# String Functions
Sprig has a number of string manipulation functions.
## trim
The `trim` function removes space from either side of a string:
```
trim " hello "
```
The above produces `hello`
## trimAll
Remove given characters from the front or back of a string:
```
trimAll "$" "$5.00"
```
The above returns `5.00` (as a string).
## trimSuffix
Trim just the suffix from a string:
```
trimSuffix "-" "hello-"
```
The above returns `hello`
## upper
Convert the entire string to uppercase:
```
upper "hello"
```
The above returns `HELLO`
## lower
Convert the entire string to lowercase:
```
lower "HELLO"
```
The above returns `hello`
## title
Convert to title case:
```
title "hello world"
```
The above returns `Hello World`
## untitle
Remove title casing. `untitle "Hello World"` produces `hello world`.
## repeat
Repeat a string multiple times:
```
repeat 3 "hello"
```
The above returns `hellohellohello`
## substr
Get a substring from a string. It takes three parameters:
- start (int)
- length (int)
- string (string)
```
substr 0 5 "hello world"
```
The above returns `hello`
## nospace
Remove all whitespace from a string.
```
nospace "hello w o r l d"
```
The above returns `helloworld`
## trunc
Truncate a string (and add no suffix)
```
trunc 5 "hello world"
```
The above produces `hello`.
## abbrev
Truncate a string with ellipses (`...`)
Parameters:
- max length
- the string
```
abbrev 5 "hello world"
```
The above returns `he...`, since it counts the width of the ellipses against the
maximum length.
## abbrevboth
Abbreviate both sides:
```
abbrevboth 5 10 "1234 5678 9123"
```
the above produces `...5678...`
It takes:
- left offset
- max length
- the string
## initials
Given multiple words, take the first letter of each word and combine.
```
initials "First Try"
```
The above returns `FT`
## randAlphaNum, randAlpha, randNumeric, and randAscii
These four functions generate random strings, but with different base character
sets:
- `randAlphaNum` uses `0-9a-zA-Z`
- `randAlpha` uses `a-zA-Z`
- `randNumeric` uses `0-9`
- `randAscii` uses all printable ASCII characters
Each of them takes one parameter: the integer length of the string.
```
randNumeric 3
```
The above will produce a random string with three digits.
## wrap
Wrap text at a given column count:
```
wrap 80 $someText
```
The above will wrap the string in `$someText` at 80 columns.
## wrapWith
`wrapWith` works as `wrap`, but lets you specify the string to wrap with.
(`wrap` uses `\n`)
```
wrapWith 5 "\t" "Hello World"
```
The above produces `hello world` (where the whitespace is an ASCII tab
character)
## contains
Test to see if one string is contained inside of another:
```
contains "cat" "catch"
```
The above returns `true` because `catch` contains `cat`.
## hasPrefix and hasSuffix
The `hasPrefix` and `hasSuffix` functions test whether a string has a given
prefix or suffix:
```
hasPrefix "cat" "catch"
```
The above returns `true` because `catch` has the prefix `cat`.
## quote and squote
These functions wrap a string in double quotes (`quote`) or single quotes
(`squote`).
## cat
The `cat` function concatenates multiple strings together into one, separating
them with spaces:
```
cat "hello" "beautiful" "world"
```
The above produces `hello beautiful world`
## indent
The `indent` function indents every line in a given string to the specified
indent width. This is useful when aligning multi-line strings:
```
indent 4 $lots_of_text
```
The above will indent every line of text by 4 space characters.
## replace
Perform simple string replacement.
It takes three arguments:
- string to replace
- string to replace with
- source string
```
"I Am Henry VIII" | replace " " "-"
```
The above will produce `I-Am-Henry-VIII`
## plural
Pluralize a string.
```
len $fish | plural "one anchovy" "many anchovies"
```
In the above, if the length of the string is 1, the first argument will be
printed (`one anchovy`). Otherwise, the second argument will be printed
(`many anchovies`).
The arguments are:
- singular string
- plural string
- length integer
NOTE: Sprig does not currently support languages with more complex pluralization
rules. And `0` is considered a plural because the English language treats it
as such (`zero anchovies`). The Sprig developers are working on a solution for
better internationalization.
## See Also...
The [Conversion Functions](conversion.html) contain functions for converting
strings. The [String Slice Functions](string_slice.html) contains functions
for working with an array of strings.

Sprig: Template functions for Go.
This package contains a number of utility functions for working with data
inside of Go `html/template` and `text/template` files.
To add these functions, use the `template.Funcs()` method:
t := templates.New("foo").Funcs(sprig.FuncMap())
Note that you should add the function map before you parse any template files.
In several cases, Sprig reverses the order of arguments from the way they
appear in the standard library. This is to make it easier to pipe
arguments into functions.
Date Functions
- date FORMAT TIME: Format a date, where a date is an integer type or a time.Time type, and
format is a time.Format formatting string.
- dateModify: Given a date, modify it with a duration: `date_modify "-1.5h" now`. If the duration doesn't
parse, it returns the time unaltered. See `time.ParseDuration` for info on duration strings.
- now: Current time.Time, for feeding into date-related functions.
- htmlDate TIME: Format a date for use in the value field of an HTML "date" form element.
- dateInZone FORMAT TIME TZ: Like date, but takes three arguments: format, timestamp,
timezone.
- htmlDateInZone TIME TZ: Like htmlDate, but takes two arguments: timestamp,
timezone.
String Functions
- abbrev: Truncate a string with ellipses. `abbrev 5 "hello world"` yields "he..."
- abbrevboth: Abbreviate from both sides, yielding "...lo wo..."
- trunc: Truncate a string (no suffix). `trunc 5 "Hello World"` yields "hello".
- trim: strings.TrimSpace
- trimAll: strings.Trim, but with the argument order reversed `trimAll "$" "$5.00"` or `"$5.00 | trimAll "$"`
- trimSuffix: strings.TrimSuffix, but with the argument order reversed: `trimSuffix "-" "ends-with-"`
- trimPrefix: strings.TrimPrefix, but with the argument order reversed `trimPrefix "$" "$5"`
- upper: strings.ToUpper
- lower: strings.ToLower
- nospace: Remove all space characters from a string. `nospace "h e l l o"` becomes "hello"
- title: strings.Title
- untitle: Remove title casing
- repeat: strings.Repeat, but with the arguments switched: `repeat count str`. (This simplifies common pipelines)
- substr: Given string, start, and length, return a substr.
- initials: Given a multi-word string, return the initials. `initials "Matt Butcher"` returns "MB"
- randAlphaNum: Given a length, generate a random alphanumeric sequence
- randAlpha: Given a length, generate an alphabetic string
- randAscii: Given a length, generate a random ASCII string (symbols included)
- randNumeric: Given a length, generate a string of digits.
- wrap: Force a line wrap at the given width. `wrap 80 "imagine a longer string"`
- wrapWith: Wrap a line at the given length, but using 'sep' instead of a newline. `wrapWith 50, "<br>", $html`
- contains: strings.Contains, but with the arguments switched: `contains substr str`. (This simplifies common pipelines)
- hasPrefix: strings.hasPrefix, but with the arguments switched
- hasSuffix: strings.hasSuffix, but with the arguments switched
- quote: Wrap string(s) in double quotation marks, escape the contents by adding '\' before '"'.
- squote: Wrap string(s) in double quotation marks, does not escape content.
- cat: Concatenate strings, separating them by spaces. `cat $a $b $c`.
- indent: Indent a string using space characters. `indent 4 "foo\nbar"` produces " foo\n bar"
- replace: Replace an old with a new in a string: `$name | replace " " "-"`
- plural: Choose singular or plural based on length: `len $fish | plural "one anchovy" "many anchovies"`
- sha256sum: Generate a hex encoded sha256 hash of the input
String Slice Functions:
- join: strings.Join, but as `join SEP SLICE`
- split: strings.Split, but as `split SEP STRING`. The results are returned
as a map with the indexes set to _N, where N is an integer starting from 0.
Use it like this: `{{$v := "foo/bar/baz" | split "/"}}{{$v._0}}` (Prints `foo`)
Integer Slice Functions:
- until: Given an integer, returns a slice of counting integers from 0 to one
less than the given integer: `range $i, $e := until 5`
- untilStep: Given start, stop, and step, return an integer slice starting at
'start', stopping at `stop`, and incrementing by 'step. This is the same
as Python's long-form of 'range'.
Conversions:
- atoi: Convert a string to an integer. 0 if the integer could not be parsed.
- in64: Convert a string or another numeric type to an int64.
- int: Convert a string or another numeric type to an int.
- float64: Convert a string or another numeric type to a float64.
Defaults:
- default: Give a default value. Used like this: trim " "| default "empty".
Since trim produces an empty string, the default value is returned. For
things with a length (strings, slices, maps), len(0) will trigger the default.
For numbers, the value 0 will trigger the default. For booleans, false will
trigger the default. For structs, the default is never returned (there is
no clear empty condition). For everything else, nil value triggers a default.
- empty: Return true if the given value is the zero value for its type.
Caveats: structs are always non-empty. This should match the behavior of
{{if pipeline}}, but can be used inside of a pipeline.
OS:
- env: Resolve an environment variable
- expandenv: Expand a string through the environment
File Paths:
- base: Return the last element of a path. https://golang.org/pkg/path#Base
- dir: Remove the last element of a path. https://golang.org/pkg/path#Dir
- clean: Clean a path to the shortest equivalent name. (e.g. remove "foo/.."
from "foo/../bar.html") https://golang.org/pkg/path#Clean
- ext: https://golang.org/pkg/path#Ext
- isAbs: https://golang.org/pkg/path#IsAbs
Encoding:
- b64enc: Base 64 encode a string.
- b64dec: Base 64 decode a string.
Reflection:
- typeOf: Takes an interface and returns a string representation of the type.
For pointers, this will return a type prefixed with an asterisk(`*`). So
a pointer to type `Foo` will be `*Foo`.
- typeIs: Compares an interface with a string name, and returns true if they match.
Note that a pointer will not match a reference. For example `*Foo` will not
match `Foo`.
- typeIsLike: Compares an interface with a string name and returns true if
the interface is that `name` or that `*name`. In other words, if the given
value matches the given type or is a pointer to the given type, this returns
true.
- kindOf: Takes an interface and returns a string representation of its kind.
- kindIs: Returns true if the given string matches the kind of the given interface.
Note: None of these can test whether or not something implements a given
interface, since doing so would require compiling the interface in ahead of
time.
Data Structures:
- tuple: Takes an arbitrary list of items and returns a slice of items. Its
tuple-ish properties are mainly gained through the template idiom, and not
through an API provided here.
- dict: Takes a list of name/values and returns a map[string]interface{}.
The first parameter is converted to a string and stored as a key, the
second parameter is treated as the value. And so on, with odds as keys and
evens as values. If the function call ends with an odd, the last key will
be assigned the empty string. Non-string keys are converted to strings as
follows: []byte are converted, fmt.Stringers will have String() called.
errors will have Error() called. All others will be passed through
fmt.Sprtinf("%v").
- set: Takes a dict, a key, and a value, and sets that key/value pair in
the dict. `set $dict $key $value`. For convenience, it returns the dict,
even though the dict was modified in place.
- unset: Takes a dict and a key, and deletes that key/value pair from the
dict. `unset $dict $key`. This returns the dict for convenience.
- hasKey: Takes a dict and a key, and returns boolean true if the key is in
the dict.
Math Functions:
Integer functions will convert integers of any width to `int64`. If a
string is passed in, functions will attempt to convert with
`strconv.ParseInt(s, 1064)`. If this fails, the value will be treated as 0.
- add1: Increment an integer by 1
- add: Sum an arbitrary number of integers
- sub: Subtract the second integer from the first
- div: Divide the first integer by the second
- mod: Module of first integer divided by second
- mul: Multiply integers
- max: Return the biggest of a series of one or more integers
- min: Return the smallest of a series of one or more integers
- biggest: DEPRECATED. Return the biggest of a series of one or more integers
Crypto Functions:
- genPrivateKey: Generate a private key for the given cryptosystem. If no
argument is supplied, by default it will generate a private key using
the RSA algorithm. Accepted values are `rsa`, `dsa`, and `ecdsa`.
