+GoUtils
+===========
+[![Stability: Maintenance](https://masterminds.github.io/stability/maintenance.svg)](https://masterminds.github.io/stability/maintenance.html)
+[![GoDoc](https://godoc.org/github.com/Masterminds/goutils?status.png)](https://godoc.org/github.com/Masterminds/goutils) [![Build Status](https://travis-ci.org/Masterminds/goutils.svg?branch=master)](https://travis-ci.org/Masterminds/goutils) [![Build status](https://ci.appveyor.com/api/projects/status/sc2b1ew0m7f0aiju?svg=true)](https://ci.appveyor.com/project/mattfarina/goutils)
+
+
+GoUtils provides users with utility functions to manipulate strings in various ways. It is a Go implementation of some
+string manipulation libraries of Java Apache Commons. GoUtils includes the following Java Apache Commons classes:
+* WordUtils
+* RandomStringUtils
+* StringUtils (partial implementation)
+
+## Installation
+If you have Go set up on your system, from the GOPATH directory within the command line/terminal, enter this:
+
+ go get github.com/Masterminds/goutils
+
+If you do not have Go set up on your system, please follow the [Go installation directions from the documenation](http://golang.org/doc/install), and then follow the instructions above to install GoUtils.
+
+
+## Documentation
+GoUtils doc is available here: [![GoDoc](https://godoc.org/github.com/Masterminds/goutils?status.png)](https://godoc.org/github.com/Masterminds/goutils)
+
+
+## Usage
+The code snippets below show examples of how to use GoUtils. Some functions return errors while others do not. The first instance below, which does not return an error, is the `Initials` function (located within the `wordutils.go` file).
+
+ package main
+
+ import (
+ "fmt"
+ "github.com/Masterminds/goutils"
+ )
+
+ func main() {
+
+ // EXAMPLE 1: A goutils function which returns no errors
+ fmt.Println (goutils.Initials("John Doe Foo")) // Prints out "JDF"
+
+ }
+Some functions return errors mainly due to illegal arguements used as parameters. The code example below illustrates how to deal with function that returns an error. In this instance, the function is the `Random` function (located within the `randomstringutils.go` file).
+
+ package main
+
+ import (
+ "fmt"
+ "github.com/Masterminds/goutils"
+ )
+
+ func main() {
+
+ // EXAMPLE 2: A goutils function which returns an error
+ rand1, err1 := goutils.Random (-1, 0, 0, true, true)
+
+ if err1 != nil {
+ fmt.Println(err1) // Prints out error message because -1 was entered as the first parameter in goutils.Random(...)
+ } else {
+ fmt.Println(rand1)
+ }
+
+ }
+

+
+## 3.0.0 (2019-09-12)
+
+This is a major release of the semver package which includes API changes. The Go
+API is compatible with ^1. The Go API was not changed because many people are using
+`go get` without Go modules for their applications and API breaking changes cause
+errors which we have or would need to support.
+
+The changes in this release are the handling based on the data passed into the
+functions. These are described in the added and changed sections below.
+
+### Added
+
+- StrictNewVersion function. This is similar to NewVersion but will return an
+ error if the version passed in is not a strict semantic version. For example,
+ 1.2.3 would pass but v1.2.3 or 1.2 would fail because they are not strictly
+ speaking semantic versions. This function is faster, performs fewer operations,
+ and uses fewer allocations than NewVersion.
+- Fuzzing has been performed on NewVersion, StrictNewVersion, and NewConstraint.
+ The Makefile contains the operations used. For more information on you can start
+ on Wikipedia at https://en.wikipedia.org/wiki/Fuzzing
+- Now using Go modules
+
+### Changed
+
+- NewVersion has proper prerelease and metadata validation with error messages
+ to signal an issue with either of them
+- ^ now operates using a similar set of rules to npm/js and Rust/Cargo. If the
+ version is >=1 the ^ ranges works the same as v1. For major versions of 0 the
+ rules have changed. The minor version is treated as the stable version unless
+ a patch is specified and then it is equivalent to =. One difference from npm/js
+ is that prereleases there are only to a specific version (e.g. 1.2.3).
+ Prereleases here look over multiple versions and follow semantic version
+ ordering rules. This pattern now follows along with the expected and requested
+ handling of this packaged by numerous users.
+
+## 1.5.0 (2019-09-11)
+
+### Added
+
+- #103: Add basic fuzzing for `NewVersion()` (thanks @jesse-c)

+- #20: Added MustParse function for versions (thanks @adamreese)
+- #15: Added increment methods on versions (thanks @mh-cbon)
+
+### Fixed
+
+- Issue #21: Per the SemVer spec (section 9) a pre-release is unstable and
+ might not satisfy the intended compatibility. The change here ignores pre-releases
+ on constraint checks (e.g., ~ or ^) when a pre-release is not part of the
+ constraint. For example, `^1.2.3` will ignore pre-releases while
+ `^1.2.3-alpha` will include them.
+
+## Release 1.1.1 (2016-06-30)

+# SemVer
+
+The `semver` package provides the ability to work with [Semantic Versions](http://semver.org) in Go. Specifically it provides the ability to:
+
+* Parse semantic versions
+* Sort semantic versions
+* Check if a semantic version fits within a set of constraints
+* Optionally work with a `v` prefix
+
+[![Stability:
+Active](https://masterminds.github.io/stability/active.svg)](https://masterminds.github.io/stability/active.html)
+[![](https://github.com/Masterminds/semver/workflows/Tests/badge.svg)](https://github.com/Masterminds/semver/actions)
+[![GoDoc](https://img.shields.io/static/v1?label=godoc&message=reference&color=blue)](https://pkg.go.dev/github.com/Masterminds/semver/v3)
+[![Go Report Card](https://goreportcard.com/badge/github.com/Masterminds/semver)](https://goreportcard.com/report/github.com/Masterminds/semver)
+
+If you are looking for a command line tool for version comparisons please see
+[vert](https://github.com/Masterminds/vert) which uses this library.
+
+## Package Versions
+
+There are three major versions fo the `semver` package.
+
+* 3.x.x is the new stable and active version. This version is focused on constraint
+ compatibility for range handling in other tools from other languages. It has
+ a similar API to the v1 releases. The development of this version is on the master
+ branch. The documentation for this version is below.
+* 2.x was developed primarily for [dep](https://github.com/golang/dep). There are
+ no tagged releases and the development was performed by [@sdboyer](https://github.com/sdboyer).
+ There are API breaking changes from v1. This version lives on the [2.x branch](https://github.com/Masterminds/semver/tree/2.x).
+* 1.x.x is the most widely used version with numerous tagged releases. This is the
+ previous stable and is still maintained for bug fixes. The development, to fix
+ bugs, occurs on the release-1 branch. You can read the documentation [here](https://github.com/Masterminds/semver/blob/release-1/README.md).
+
+## Parsing Semantic Versions
+
+There are two functions that can parse semantic versions. The `StrictNewVersion`
+function only parses valid version 2 semantic versions as outlined in the
+specification. The `NewVersion` function attempts to coerce a version into a
+semantic version and parse it. For example, if there is a leading v or a version
+listed without all 3 parts (e.g. `v1.2`) it will attempt to coerce it into a valid
+semantic version (e.g., 1.2.0). In both cases a `Version` object is returned
+that can be sorted, compared, and used in constraints.
+
+When parsing a version an error is returned if there is an issue parsing the
+version. For example,
+
+ v, err := semver.NewVersion("1.2.3-beta.1+build345")
+
+The version object has methods to get the parts of the version, compare it to
+other versions, convert the version back into a string, and get the original
+string. Getting the original string is useful if the semantic version was coerced
+into a valid form.
+
+## Sorting Semantic Versions
+
+A set of versions can be sorted using the `sort` package from the standard library.
+For example,
+
+```go
+raw := []string{"1.2.3", "1.0", "1.3", "2", "0.4.2",}
+vs := make([]*semver.Version, len(raw))
+for i, r := range raw {
+ v, err := semver.NewVersion(r)
+ if err != nil {
+ t.Errorf("Error parsing version: %s", err)
+ }
+
+ vs[i] = v
+}
+
+sort.Sort(semver.Collection(vs))
+```
+
+## Checking Version Constraints
+
+There are two methods for comparing versions. One uses comparison methods on
+`Version` instances and the other uses `Constraints`. There are some important
+differences to notes between these two methods of comparison.
+
+1. When two versions are compared using functions such as `Compare`, `LessThan`,
+ and others it will follow the specification and always include prereleases
+ within the comparison. It will provide an answer that is valid with the
+ comparison section of the spec at https://semver.org/#spec-item-11
+2. When constraint checking is used for checks or validation it will follow a
+ different set of rules that are common for ranges with tools like npm/js
+ and Rust/Cargo. This includes considering prereleases to be invalid if the
+ ranges does not include one. If you want to have it include pre-releases a
+ simple solution is to include `-0` in your range.
+3. Constraint ranges can have some complex rules including the shorthand use of
+ ~ and ^. For more details on those see the options below.
+
+There are differences between the two methods or checking versions because the
+comparison methods on `Version` follow the specification while comparison ranges
+are not part of the specification. Different packages and tools have taken it
+upon themselves to come up with range rules. This has resulted in differences.
+For example, npm/js and Cargo/Rust follow similar patterns while PHP has a
+different pattern for ^. The comparison features in this package follow the
+npm/js and Cargo/Rust lead because applications using it have followed similar
+patters with their versions.
+
+Checking a version against version constraints is one of the most featureful
+parts of the package.
+
+```go
+c, err := semver.NewConstraint(">= 1.2.3")
+if err != nil {
+ // Handle constraint not being parsable.
+}
+
+v, err := semver.NewVersion("1.3")
+if err != nil {
+ // Handle version not being parsable.
+}
+// Check if the version meets the constraints. The a variable will be true.
+a := c.Check(v)
+```
+
+### Basic Comparisons
+
+There are two elements to the comparisons. First, a comparison string is a list
+of space or comma separated AND comparisons. These are then separated by || (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
+
+### Working With Prerelease Versions
+
+Pre-releases, for those not familiar with them, are used for software releases
+prior to stable or generally available releases. Examples of prereleases include
+development, alpha, beta, and release candidate releases. A prerelease may be
+a version such as `1.2.3-beta.1` while the stable release would be `1.2.3`. In the
+order of precedence, prereleases come before their associated releases. In this
+example `1.2.3-beta.1 < 1.2.3`.
+
+According to the Semantic Version specification prereleases 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 using constraints without a prerelease comparator will skip
+prerelease versions. For example, `>=1.2.3` will skip prereleases when looking
+at a list of releases while `>=1.2.3-0` will evaluate and find prereleases.
+
+The reason for the `0` as a pre-release version in the example comparison is
+because pre-releases can only contain ASCII alphanumerics and hyphens (along with
+`.` separators), per the spec. Sorting happens in ASCII sort order, again per the
+spec. The lowest character is a `0` in ASCII sort order
+(see an [ASCII Table](http://www.asciitable.com/))
+
+Understanding ASCII sort ordering is important because A-Z comes before a-z. That
+means `>=1.2.3-BETA` will return `1.2.3-alpha`. What you might expect from case
+sensitivity doesn't apply here. This is due to ASCII sort ordering which is what
+the spec specifies.
+
+### 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 patch 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 once a stable
+(1.0.0) release has occurred. Prior to a 1.0.0 release the minor versions acts
+as the API stability level. 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`
+* `^0.2.3` is equivalent to `>=0.2.3 <0.3.0`
+* `^0.2` is equivalent to `>=0.2.0 <0.3.0`
+* `^0.0.3` is equivalent to `>=0.0.3 <0.0.4`
+* `^0.0` is equivalent to `>=0.0.0 <0.1.0`
+* `^0` is equivalent to `>=0.0.0 <1.0.0`
+
+## Validation
+
+In addition to testing a version against a constraint, a version can be validated
+against a constraint. When validation fails a slice of errors containing why a
+version didn't meet the constraint is returned. For example,
+
+```go
+c, err := semver.NewConstraint("<= 1.2.3, >= 1.4")
+if err != nil {
+ // Handle constraint not being parseable.
+}
+
+v, err := semver.NewVersion("1.3")
+if err != nil {
+ // Handle version not being parseable.
+}
+
+// Validate a version against a constraint.
+a, msgs := c.Validate(v)
+// a is false
+for _, m := range msgs {
+ fmt.Println(m)
+
+ // Loops over the errors which would read
+ // "1.3 is greater than 1.2.3"
+ // "1.3 is less than 1.4"
+}
+```

+Package semver provides the ability to work with Semantic Versions (http://semver.org) in Go.
+
+Specifically it provides the ability to:
+
+ - Parse semantic versions
+ - Sort semantic versions
+ - Check if a semantic version fits within a set of constraints
+ - Optionally work with a `v` prefix
+
+# Parsing Semantic Versions
+
+There are two functions that can parse semantic versions. The `StrictNewVersion`
+function only parses valid version 2 semantic versions as outlined in the
+specification. The `NewVersion` function attempts to coerce a version into a
+semantic version and parse it. For example, if there is a leading v or a version
+listed without all 3 parts (e.g. 1.2) it will attempt to coerce it into a valid
+semantic version (e.g., 1.2.0). In both cases a `Version` object is returned
+that can be sorted, compared, and used in constraints.
+
+When parsing a version an optional error can be returned if there is an issue
+parsing the version. For example,
+
+ v, err := semver.NewVersion("1.2.3-beta.1+b345")
+
+The version object has methods to get the parts of the version, compare it to
+other versions, convert the version back into a string, and get the original
+string. For more details please see the documentation
+at https://godoc.org/github.com/Masterminds/semver.
+
+# Sorting Semantic Versions
+
+A set of versions can be sorted using the `sort` package from the standard library.
+For example,
+
+ raw := []string{"1.2.3", "1.0", "1.3", "2", "0.4.2",}
+ vs := make([]*semver.Version, len(raw))
+ for i, r := range raw {
+ v, err := semver.NewVersion(r)
+ if err != nil {
+ t.Errorf("Error parsing version: %s", err)
+ }
+
+ vs[i] = v
+ }
+
+ sort.Sort(semver.Collection(vs))
+
+# Checking Version Constraints and Comparing Versions
+
+There are two methods for comparing versions. One uses comparison methods on
+`Version` instances and the other is using Constraints. There are some important
+differences to notes between these two methods of comparison.
+
+ 1. When two versions are compared using functions such as `Compare`, `LessThan`,
+ and others it will follow the specification and always include prereleases
+ within the comparison. It will provide an answer valid with the comparison
+ spec section at https://semver.org/#spec-item-11
+ 2. When constraint checking is used for checks or validation it will follow a
+ different set of rules that are common for ranges with tools like npm/js
+ and Rust/Cargo. This includes considering prereleases to be invalid if the
+ ranges does not include on. If you want to have it include pre-releases a
+ simple solution is to include `-0` in your range.
+ 3. Constraint ranges can have some complex rules including the shorthard use of
+ ~ and ^. For more details on those see the options below.
+
+There are differences between the two methods or checking versions because the
+comparison methods on `Version` follow the specification while comparison ranges
+are not part of the specification. Different packages and tools have taken it
+upon themselves to come up with range rules. This has resulted in differences.
+For example, npm/js and Cargo/Rust follow similar patterns which PHP has a
+different pattern for ^. The comparison features in this package follow the
+npm/js and Cargo/Rust lead because applications using it have followed similar
+patters with their versions.
+
+Checking a version against version constraints is one of the most featureful
+parts of the package.
+
+ c, err := semver.NewConstraint(">= 1.2.3")
+ if err != nil {
+ // Handle constraint not being parsable.
+ }
+
+ v, err := semver.NewVersion("1.3")
+ if err != nil {
+ // Handle version not being parsable.
+ }
+ // Check if the version meets the constraints. The a variable will be true.
+ a := c.Check(v)
+
+# Basic Comparisons
+
+There are two elements to the comparisons. First, a comparison string is a list
+of comma or space separated AND comparisons. These are then separated by || (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. This can also be written as
+`">= 1.2, < 3.0.0 || >= 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
+
+# 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 tilde operation. 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 once a stable
+(1.0.0) release has occurred. Prior to a 1.0.0 release the minor versions acts
+as the API stability level. 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`
+ - `^0.2.3` is equivalent to `>=0.2.3 <0.3.0`
+ - `^0.2` is equivalent to `>=0.2.0 <0.3.0`
+ - `^0.0.3` is equivalent to `>=0.0.3 <0.0.4`
+ - `^0.0` is equivalent to `>=0.0.0 <0.1.0`
+ - `^0` is equivalent to `>=0.0.0 <1.0.0`
+
+# Validation
+
+In addition to testing a version against a constraint, a version can be validated
+against a constraint. When validation fails a slice of errors containing why a
+version didn't meet the constraint is returned. For example,
+
+ c, err := semver.NewConstraint("<= 1.2.3, >= 1.4")
+ if err != nil {
+ // Handle constraint not being parseable.
+ }
+
+ v, _ := semver.NewVersion("1.3")
+ if err != nil {
+ // Handle version not being parseable.
+ }
+
+ // Validate a version against a constraint.
+ a, msgs := c.Validate(v)
+ // a is false
+ for _, m := range msgs {
+ fmt.Println(m)
+
+ // Loops over the errors which would read
+ // "1.3 is greater than 1.2.3"
+ // "1.3 is less than 1.4"
+ }

+
+### Fixed
+
+## Release 2.19.0 (2019-03-02)
+
+IMPORTANT: This release reverts a change from 2.18.0
+
+In the previous release (2.18), we prematurely merged a partial change to the crypto functions that led to creating two sets of crypto functions (I blame @technosophos -- since that's me). This release rolls back that change, and does what was originally intended: It alters the existing crypto functions to use secure random.
+
+We debated whether this classifies as a change worthy of major revision, but given the proximity to the last release, we have decided that treating 2.18 as a faulty release is the correct course of action. We apologize for any inconvenience.
+
+### Changed
+

+- Remove extra period 1eb7729 (Matthew Lorimor)
+- Make random string functions use crypto by default 6ceff26 (Matthew Lorimor)

+# Sprig: Template functions for Go templates
+
+[![GoDoc](https://img.shields.io/static/v1?label=godoc&message=reference&color=blue)](https://pkg.go.dev/github.com/Masterminds/sprig/v3)
+[![Go Report Card](https://goreportcard.com/badge/github.com/Masterminds/sprig)](https://goreportcard.com/report/github.com/Masterminds/sprig)
+[![Stability: Sustained](https://masterminds.github.io/stability/sustained.svg)](https://masterminds.github.io/stability/sustained.html)
+[![](https://github.com/Masterminds/sprig/workflows/Tests/badge.svg)](https://github.com/Masterminds/sprig/actions)
+
+The Go language comes with a [built-in template
+language](http://golang.org/pkg/text/template/), but not
+very many template functions. Sprig is a library that provides more than 100 commonly
+used template functions.
+
+It is inspired by the template functions found in
+[Twig](http://twig.sensiolabs.org/documentation) and in various
+JavaScript libraries, such as [underscore.js](http://underscorejs.org/).
+
+## IMPORTANT NOTES
+
+Sprig leverages [mergo](https://github.com/imdario/mergo) to handle merges. In
+its v0.3.9 release, there was a behavior change that impacts merging template
+functions in sprig. It is currently recommended to use v0.3.10 or later of that package.
+Using v0.3.9 will cause sprig tests to fail.
+
+## Package Versions
+
+There are two active major versions of the `sprig` package.
+
+* v3 is currently stable release series on the `master` branch. The Go API should
+ remain compatible with v2, the current stable version. Behavior change behind
+ some functions is the reason for the new major version.
+* v2 is the previous stable release series. It has been more than three years since
+ the initial release of v2. You can read the documentation and see the code
+ on the [release-2](https://github.com/Masterminds/sprig/tree/release-2) branch.
+ Bug fixes to this major version will continue for some time.
+
+## Usage
+
+**Template developers**: Please use Sprig's [function documentation](http://masterminds.github.io/sprig/) for
+detailed instructions and code snippets for the >100 template functions available.
+
+**Go developers**: If you'd like to include Sprig as a library in your program,
+our API documentation is available [at GoDoc.org](http://godoc.org/github.com/Masterminds/sprig).
+
+For standard usage, read on.
+
+### Load the Sprig library
+
+To load the Sprig `FuncMap`:
+
+```go
+
+import (
+ "github.com/Masterminds/sprig/v3"
+ "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")
+)
+
+
+```
+
+### Calling 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). For example, this:
+
+```
+{{ "hello!" | upper | repeat 5 }}
+```
+
+produces this:
+
+```
+HELLO!HELLO!HELLO!HELLO!HELLO!
+```
+
+## Principles Driving Our Function Selection
+
+We followed these principles to decide which functions to add and how to implement them:
+
+- Use template functions to build layout. 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.
+- 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.

+Package sprig provides 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.
+
+See http://masterminds.github.io/sprig/ for more detailed documentation on each of the available functions.
