+# Sprig: Template functions for Go templates
+
+The Go language comes with a [built-in template
+language](http://golang.org/pkg/text/template/), but not
+very many template functions. This library provides a group of commonly
+used template functions.
+
+It is inspired by the template functions found in
+[Twig](http://twig.sensiolabs.org/documentation).
+
+[![Build Status](https://travis-ci.org/Masterminds/sprig.svg?branch=master)](https://travis-ci.org/Masterminds/sprig)
+
+## Usage
+
+API documentation is available [at GoDoc.org](http://godoc.org/github.com/Masterminds/sprig), but
+read on for standard usage.
+
+### Load the Sprig library
+
+To load the Sprig `FuncMap`:
+
+```go
+
+import (
+  "github.com/Masterminds/sprig"
+  "html/template"
+)
+
+// This example illustrates that the FuncMap *must* be set before the
+// templates themselves are loaded.
+tpl := template.Must(
+  template.New("base").Funcs(sprig.FuncMap()).ParseGlob("*.html")
+)
+
+
+```
+
+### Call the functions inside of templates
+
+By convention, all functions are lowercase. This seems to follow the Go
+idiom for template functions (as opposed to template methods, which are
+TitleCase).
+
+
+Example:
+
+```
+{{ "hello!" | upper | repeat 5 }}
+```
+
+Produces:
+
+```
+HELLO!HELLO!HELLO!HELLO!HELLO!
+```
+
+## Functions
+
+### Date Functions
+
+- date: 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: Format a date for use in the value field of an HTML "date" form element.
+- dateInZone: Like date, but takes three arguments: format, timestamp,
+  timezone.
+- htmlDateInZone: Like htmlDate, but takes two arguments: timestamp,
+  timezone.
+
+### String Functions
+
+- 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 "-" "5-"`
+- trimPrefix: strings.TrimPrefix, but with the argument order reversed `trimPrefix "$" "$5"`
+- upper: strings.ToUpper
+- lower: strings.ToLower
+- title: strings.Title
+- repeat: strings.Repeat, but with the arguments switched: `repeat count str`. (This simplifies common pipelines)
+- substr: Given string, start, and length, return a substr.
+- nospace: Remove all spaces from a string. `h e l l o` becomes
+  `hello`.
+- abbrev: Truncate a string with ellipses
+- trunc: Truncate a string (no suffix). `trunc 5 "Hello World"` yields "hello".
+- abbrevboth: Truncate both sides of a string with ellipses
+- untitle: Remove title case
+- intials: Given multiple words, return the first letter of each
+  word
+- randAlphaNum: Generate a random alpha-numeric string
+- randAlpha: Generate a random alphabetic string
+- randAscii: Generate a random ASCII string, including symbols
+- randNumeric: Generate a random numeric string
+- wrap: Wrap text at the given column count
+- wrapWith: Wrap text at the given column count, and with the given
+  string for a line terminator: `wrap 50 "\n\t" $string`
+- contains: strings.Contains, but with the arguments switched: `contains "cat" "uncatch"`. (This simplifies common pipelines)
+- hasPrefix: strings.hasPrefix, but with the arguments switched: `hasPrefix "cat" "catch"`.
+- hasSuffix: strings.hasSuffix, but with the arguments switched: `hasSuffix "cat" "ducat"`.
+- quote: Wrap strings in double quotes. `quote "a" "b"` returns `"a"
+  "b"`
+- squote: Wrap strings in single quotes.
+- 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 $fish | plural
+  "one anchovy" "many anchovies"`
+- uuidv4: Generate a UUID v4 string
+- sha256sum: Generate a hex encoded sha256 hash of the input
+
+### String Slice Functions:
+
+- join: strings.Join, but as `join SEP SLICE`
+- split: strings.Split, but as `split SEP STRING`. The results are returned
+  as a map with the indexes set to _N, where N is an integer starting from 0.
+  Use it like this: `{{$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.
+- int: Convert a string or numeric to an int
+- int64: Convert a string or numeric to an int64
+- float64: Convert a string or numeric 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: Returns true if the given value is the zero value for that
+  type. Structs are always non-empty.
+
+### OS:
+
+- env: Read an environment variable.
+- expandenv: Expand all environment variables in a string.
+
+### Encoding:
+
+- b32enc: Encode a string into a Base32 string
+- b32dec: Decode a string from a Base32 string
+- b64enc: Encode a string into a Base64 string
+- b64dec: Decode a string from a Base64 string
+
+### Data Structures:
+
+- tuple: A sequence of related objects. It is implemented as a
+  `[]interface{}`, where each item can be accessed using `index`.
+- 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").
+
+```
+{{$t := tuple 1 "a" "foo"}}
+{{index $t 2}}{{index $t 0 }}{{index $t 1}}
+{{/* Prints foo1a *}}
+```
+
+### 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: returns true if the interface is of the given type, or
+  is a pointer to the given type.
+- 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.
+
+
+### Math Functions:
+
+Integer functions will convert integers of any width to `int64`. If a
+string is passed in, functions will attempt to conver with
+`strconv.ParseInt(s, 1064)`. If this fails, the value will be treated as 0.
+
+- add1: Increment an integer by 1
+- add: Sum integers. `add 1 2 3` renders `6`
+- 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 integers
+- max (biggest): Return the biggest of a series of integers. `max 1 2 3`
+  returns `3`.
+- min: Return the smallest of a series of integers. `min 1 2 3` returns
+  `1`.
+
+
+## Principles:
+
+The following principles were used in deciding on which functions to add, and
+determining how to implement them.
+
+- Template functions should be used to build layout. Therefore, the following
+  types of operations are within the domain of template functions:
+  - Formatting
+  - Layout
+  - Simple type conversions
+  - Utilities that assist in handling common formatting and layout needs (e.g. arithmetic)
+- Template functions should not return errors unless there is no way to print
+  a sensible value. For example, converting a string to an integer should not
+  produce an error if conversion fails. Instead, it should display a default
+  value that can be displayed.
+- Simple math is necessary for grid layouts, pagers, and so on. Complex math
+  (anything other than arithmetic) should be done outside of templates.
+- Template functions only deal with the data passed into them. They never retrieve
+  data from a source.
+- Finally, do not override core Go template functions.

+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
+
+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").
+
+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`.
