-
-This library implements the edwards25519 elliptic curve, exposing the necessary APIs to build a wide array of higher-level primitives.
-Read the docs at [pkg.go.dev/filippo.io/edwards25519](https://pkg.go.dev/filippo.io/edwards25519).
-
-The code is originally derived from Adam Langley's internal implementation in the Go standard library, and includes George Tankersley's [performance improvements](https://golang.org/cl/71950). It was then further developed by Henry de Valence for use in ristretto255, and was finally [merged back into the Go standard library](https://golang.org/cl/276272) as of Go 1.17. It now tracks the upstream codebase and extends it with additional functionality.
-
-Most users don't need this package, and should instead use `crypto/ed25519` for signatures, `golang.org/x/crypto/curve25519` for Diffie-Hellman, or `github.com/gtank/ristretto255` for prime order group logic. However, for anyone currently using a fork of `crypto/internal/edwards25519`/`crypto/ed25519/internal/edwards25519` or `github.com/agl/edwards25519`, this package should be a safer, faster, and more powerful alternative.
-
-Since this package is meant to curb proliferation of edwards25519 implementations in the Go ecosystem, it welcomes requests for new APIs or reviewable performance improvements.

-# Squirrel - fluent SQL generator for Go
-
-```go
-import "github.com/Masterminds/squirrel"
-```
-
-
-[![GoDoc](https://godoc.org/github.com/Masterminds/squirrel?status.png)](https://godoc.org/github.com/Masterminds/squirrel)
-[![Build Status](https://api.travis-ci.org/Masterminds/squirrel.svg?branch=master)](https://travis-ci.org/Masterminds/squirrel)
-
-**Squirrel is not an ORM.** For an application of Squirrel, check out
-[structable, a table-struct mapper](https://github.com/Masterminds/structable)
-
-
-Squirrel helps you build SQL queries from composable parts:
-
-```go
-import sq "github.com/Masterminds/squirrel"
-
-users := sq.Select("*").From("users").Join("emails USING (email_id)")
-
-active := users.Where(sq.Eq{"deleted_at": nil})
-
-sql, args, err := active.ToSql()
-
-sql == "SELECT * FROM users JOIN emails USING (email_id) WHERE deleted_at IS NULL"
-```
-
-```go
-sql, args, err := sq.
-    Insert("users").Columns("name", "age").
-    Values("moe", 13).Values("larry", sq.Expr("? + 5", 12)).
-    ToSql()
-
-sql == "INSERT INTO users (name,age) VALUES (?,?),(?,? + 5)"
-```
-
-Squirrel can also execute queries directly:
-
-```go
-stooges := users.Where(sq.Eq{"username": []string{"moe", "larry", "curly", "shemp"}})
-three_stooges := stooges.Limit(3)
-rows, err := three_stooges.RunWith(db).Query()
-
-// Behaves like:
-rows, err := db.Query("SELECT * FROM users WHERE username IN (?,?,?,?) LIMIT 3",
-                      "moe", "larry", "curly", "shemp")
-```
-
-Squirrel makes conditional query building a breeze:
-
-```go
-if len(q) > 0 {
-    users = users.Where("name LIKE ?", fmt.Sprint("%", q, "%"))
-}
-```
-
-Squirrel wants to make your life easier:
-
-```go
-// StmtCache caches Prepared Stmts for you
-dbCache := sq.NewStmtCache(db)
-
-// StatementBuilder keeps your syntax neat
-mydb := sq.StatementBuilder.RunWith(dbCache)
-select_users := mydb.Select("*").From("users")
-```
-
-Squirrel loves PostgreSQL:
-
-```go
-psql := sq.StatementBuilder.PlaceholderFormat(sq.Dollar)
-
-// You use question marks for placeholders...
-sql, _, _ := psql.Select("*").From("elephants").Where("name IN (?,?)", "Dumbo", "Verna").ToSql()
-
-/// ...squirrel replaces them using PlaceholderFormat.
-sql == "SELECT * FROM elephants WHERE name IN ($1,$2)"
-
-
-/// You can retrieve id ...
-query := sq.Insert("nodes").
-    Columns("uuid", "type", "data").
-    Values(node.Uuid, node.Type, node.Data).
-    Suffix("RETURNING \"id\"").
-    RunWith(m.db).
-    PlaceholderFormat(sq.Dollar)
-
-query.QueryRow().Scan(&node.id)
-```
-
-You can escape question marks by inserting two question marks:
-
-```sql
-SELECT * FROM nodes WHERE meta->'format' ??| array[?,?]
-```
-
-will generate with the Dollar Placeholder:
-
-```sql
-SELECT * FROM nodes WHERE meta->'format' ?| array[$1,$2]
-```
-
-## FAQ
-
-* **How can I build an IN query on composite keys / tuples, e.g. `WHERE (col1, col2) IN ((1,2),(3,4))`? ([#104](https://github.com/Masterminds/squirrel/issues/104))**
-
-    Squirrel does not explicitly support tuples, but you can get the same effect with e.g.:
-
-    ```go
-    sq.Or{
-      sq.Eq{"col1": 1, "col2": 2},
-      sq.Eq{"col1": 3, "col2": 4}}
-    ```
-
-    ```sql
-    WHERE (col1 = 1 AND col2 = 2) OR (col1 = 3 AND col2 = 4)
-    ```
-
-    (which should produce the same query plan as the tuple version)
-
-* **Why doesn't `Eq{"mynumber": []uint8{1,2,3}}` turn into an `IN` query? ([#114](https://github.com/Masterminds/squirrel/issues/114))**
-
-    Values of type `[]byte` are handled specially by `database/sql`. In Go, [`byte` is just an alias of `uint8`](https://golang.org/pkg/builtin/#byte), so there is no way to distinguish `[]uint8` from `[]byte`.
-
-* **Some features are poorly documented!**
-
-    This isn't a frequent complaints section!
-
-* **Some features are poorly documented?**
-
-    Yes. The tests should be considered a part of the documentation; take a look at those for ideas on how to express more complex queries.

-**What does this mean?** I do not have time to fix issues myself. The only way fixes or new features will be added is by people submitting PRs. If you are interested in taking over maintenance and have a history of contributions to Kingpin, please let me know.
-
-**Current status.** Kingpin is largely feature stable. There hasn't been a need to add new features in a while, but there are some bugs that should be fixed.
-
-**Why?** I no longer use Kingpin personally (I now use [kong](https://github.com/alecthomas/kong)). Rather than leave the project in a limbo of people filing issues and wondering why they're not being worked on, I believe this notice will more clearly set expectations.

-## Overview
-
-Kingpin is a [fluent-style](http://en.wikipedia.org/wiki/Fluent_interface),
-type-safe command-line parser. It supports flags, nested commands, and
-positional arguments.
-
-Install it with:
-
-    $ go get github.com/alecthomas/kingpin/v2
-
-It looks like this:
-
-```go
-var (
-  verbose = kingpin.Flag("verbose", "Verbose mode.").Short('v').Bool()
-  name    = kingpin.Arg("name", "Name of user.").Required().String()
-)
-
-func main() {
-  kingpin.Parse()
-  fmt.Printf("%v, %s\n", *verbose, *name)
-}
-```
-
-More [examples](https://github.com/alecthomas/kingpin/tree/master/_examples) are available.
-
-Second to parsing, providing the user with useful help is probably the most
-important thing a command-line parser does. Kingpin tries to provide detailed
-contextual help if `--help` is encountered at any point in the command line
-(excluding after `--`).
-
-## Features
-
-- Help output that isn't as ugly as sin.
-- Fully [customisable help](#custom-help), via Go templates.
-- Parsed, type-safe flags (`kingpin.Flag("f", "help").Int()`)
-- Parsed, type-safe positional arguments (`kingpin.Arg("a", "help").Int()`).
-- Parsed, type-safe, arbitrarily deep commands (`kingpin.Command("c", "help")`).
-- Support for required flags and required positional arguments (`kingpin.Flag("f", "").Required().Int()`).
-- Support for arbitrarily nested default commands (`command.Default()`).
-- Callbacks per command, flag and argument (`kingpin.Command("c", "").Action(myAction)`).
-- POSIX-style short flag combining (`-a -b` -> `-ab`).
-- Short-flag+parameter combining (`-a parm` -> `-aparm`).
-- Read command-line from files (`@<file>`).
-- Automatically generate man pages (`--help-man`).
-
-## User-visible changes between v1 and v2
-
-### Flags can be used at any point after their definition.
-
-Flags can be specified at any point after their definition, not just
-*immediately after their associated command*. From the chat example below, the
-following used to be required:
-
-```
-$ chat --server=chat.server.com:8080 post --image=~/Downloads/owls.jpg pics
-```
-
-But the following will now work:
-
-```
-$ chat post --server=chat.server.com:8080 --image=~/Downloads/owls.jpg pics
-```
-
-### Short flags can be combined with their parameters
-
-Previously, if a short flag was used, any argument to that flag would have to
-be separated by a space. That is no longer the case.
-
-## API changes between v1 and v2
-
-- `ParseWithFileExpansion()` is gone. The new parser directly supports expanding `@<file>`.
-- Added `FatalUsage()` and `FatalUsageContext()` for displaying an error + usage and terminating.
-- `Dispatch()` renamed to `Action()`.
-- Added `ParseContext()` for parsing a command line into its intermediate context form without executing.
-- Added `Terminate()` function to override the termination function.
-- Added `UsageForContextWithTemplate()` for printing usage via a custom template.
-- Added `UsageTemplate()` for overriding the default template to use. Two templates are included:
-    1. `DefaultUsageTemplate` - default template.
-    2. `CompactUsageTemplate` - compact command template for larger applications.
-

-
-### [V2](https://github.com/alecthomas/kingpin/v2) is the current stable version
-
-Installation:
-
-```sh
-$ go get github.com/alecthomas/kingpin/v2
-```
-
-### [V1](https://gopkg.in/alecthomas/kingpin.v1) is the OLD stable version
-
-Installation:
-
-```sh
-$ go get gopkg.in/alecthomas/kingpin.v1
-```
-
-## Change History
-
-- *2015-09-19* -- Stable v2.1.0 release.
-    - Added `command.Default()` to specify a default command to use if no other
-      command matches. This allows for convenient user shortcuts.
-    - Exposed `HelpFlag` and `VersionFlag` for further customisation.
-    - `Action()` and `PreAction()` added and both now support an arbitrary
-      number of callbacks.
-    - `kingpin.SeparateOptionalFlagsUsageTemplate`.
-    - `--help-long` and `--help-man` (hidden by default) flags.
-    - Flags are "interspersed" by default, but can be disabled with `app.Interspersed(false)`.
-    - Added flags for all simple builtin types (int8, uint16, etc.) and slice variants.
-    - Use `app.Writer(os.Writer)` to specify the default writer for all output functions.
-    - Dropped `os.Writer` prefix from all printf-like functions.
-
-- *2015-05-22* -- Stable v2.0.0 release.
-    - Initial stable release of v2.0.0.
-    - Fully supports interspersed flags, commands and arguments.
-    - Flags can be present at any point after their logical definition.
-    - Application.Parse() terminates if commands are present and a command is not parsed.
-    - Dispatch() -> Action().
-    - Actions are dispatched after all values are populated.
-    - Override termination function (defaults to os.Exit).
-    - Override output stream (defaults to os.Stderr).
-    - Templatised usage help, with default and compact templates.
-    - Make error/usage functions more consistent.
-    - Support argument expansion from files by default (with @<file>).
-    - Fully public data model is available via .Model().
-    - Parser has been completely refactored.
-    - Parsing and execution has been split into distinct stages.
-    - Use `go generate` to generate repeated flags.
-    - Support combined short-flag+argument: -fARG.
-
-- *2015-01-23* -- Stable v1.3.4 release.
-    - Support "--" for separating flags from positional arguments.
-    - Support loading flags from files (ParseWithFileExpansion()). Use @FILE as an argument.
-    - Add post-app and post-cmd validation hooks. This allows arbitrary validation to be added.
-    - A bunch of improvements to help usage and formatting.
-    - Support arbitrarily nested sub-commands.
-
-- *2014-07-08* -- Stable v1.2.0 release.
-    - Pass any value through to `Strings()` when final argument.
-      Allows for values that look like flags to be processed.
-    - Allow `--help` to be used with commands.
-    - Support `Hidden()` flags.
-    - Parser for [units.Base2Bytes](https://github.com/alecthomas/units)
-      type. Allows for flags like `--ram=512MB` or `--ram=1GB`.
-    - Add an `Enum()` value, allowing only one of a set of values
-      to be selected. eg. `Flag(...).Enum("debug", "info", "warning")`.
-
-- *2014-06-27* -- Stable v1.1.0 release.
-    - Bug fixes.
-    - Always return an error (rather than panicing) when misconfigured.
-    - `OpenFile(flag, perm)` value type added, for finer control over opening files.
-    - Significantly improved usage formatting.
-
-- *2014-06-19* -- Stable v1.0.0 release.
-    - Support [cumulative positional](#consuming-all-remaining-arguments) arguments.
-    - Return error rather than panic when there are fatal errors not caught by
-      the type system. eg. when a default value is invalid.
-    - Use gokpg.in.
-
-- *2014-06-10* -- Place-holder streamlining.
-    - Renamed `MetaVar` to `PlaceHolder`.
-    - Removed `MetaVarFromDefault`. Kingpin now uses [heuristics](#place-holders-in-help)
-      to determine what to display.
-
-## Examples
-
-### Simple Example
-
-Kingpin can be used for simple flag+arg applications like so:
-
-```
-$ ping --help
-usage: ping [<flags>] <ip> [<count>]
-
-Flags:
-  --debug            Enable debug mode.
-  --help             Show help.
-  -t, --timeout=5s   Timeout waiting for ping.
-
-Args:
-  <ip>        IP address to ping.
-  [<count>]   Number of packets to send
-$ ping 1.2.3.4 5
-Would ping: 1.2.3.4 with timeout 5s and count 5
-```
-
-From the following source:
-
-```go
-package main
-
-import (
-  "fmt"
-
-  "github.com/alecthomas/kingpin/v2"
-)
-
-var (
-  debug   = kingpin.Flag("debug", "Enable debug mode.").Bool()
-  timeout = kingpin.Flag("timeout", "Timeout waiting for ping.").Default("5s").Envar("PING_TIMEOUT").Short('t').Duration()
-  ip      = kingpin.Arg("ip", "IP address to ping.").Required().IP()
-  count   = kingpin.Arg("count", "Number of packets to send").Int()
-)
-
-func main() {
-  kingpin.Version("0.0.1")
-  kingpin.Parse()
-  fmt.Printf("Would ping: %s with timeout %s and count %d\n", *ip, *timeout, *count)
-}
-```
-
-#### Reading arguments from a file
-Kingpin supports reading arguments from a file.
-Create a file with the corresponding arguments:
-```
-echo -t=5\n > args
-```
-And now supply it:
-```
-$ ping @args
-```
-
-### Complex Example
-
-Kingpin can also produce complex command-line applications with global flags,
-subcommands, and per-subcommand flags, like this:
-
-```
-$ chat --help
-usage: chat [<flags>] <command> [<flags>] [<args> ...]
-
-A command-line chat application.
-
-Flags:
-  --help              Show help.
-  --debug             Enable debug mode.
-  --server=127.0.0.1  Server address.
-
-Commands:
-  help [<command>]
-    Show help for a command.
-
-  register <nick> <name>
-    Register a new user.
-
-  post [<flags>] <channel> [<text>]
-    Post a message to a channel.
-
-$ chat help post
-usage: chat [<flags>] post [<flags>] <channel> [<text>]
-
-Post a message to a channel.
-
-Flags:
-  --image=IMAGE  Image to post.
-
-Args:
-  <channel>  Channel to post to.
-  [<text>]   Text to post.
-
-$ chat post --image=~/Downloads/owls.jpg pics
-...
-```
-
-From this code:
-
-```go
-package main
-
-import (
-  "os"
-  "strings"
-  "github.com/alecthomas/kingpin/v2"
-)
-
-var (
-  app      = kingpin.New("chat", "A command-line chat application.")
-  debug    = app.Flag("debug", "Enable debug mode.").Bool()
-  serverIP = app.Flag("server", "Server address.").Default("127.0.0.1").IP()
-
-  register     = app.Command("register", "Register a new user.")
-  registerNick = register.Arg("nick", "Nickname for user.").Required().String()
-  registerName = register.Arg("name", "Name of user.").Required().String()
-
-  post        = app.Command("post", "Post a message to a channel.")
-  postImage   = post.Flag("image", "Image to post.").File()
-  postChannel = post.Arg("channel", "Channel to post to.").Required().String()
-  postText    = post.Arg("text", "Text to post.").Strings()
-)
-
-func main() {
-  switch kingpin.MustParse(app.Parse(os.Args[1:])) {
-  // Register user
-  case register.FullCommand():
-    println(*registerNick)
-
-  // Post message
-  case post.FullCommand():
-    if *postImage != nil {
-    }
-    text := strings.Join(*postText, " ")
-    println("Post:", text)
-  }
-}
-```
-
-## Reference Documentation
-
-### Displaying errors and usage information
-
-Kingpin exports a set of functions to provide consistent errors and usage
-information to the user.
-
-Error messages look something like this:
-
-    <app>: error: <message>
-
-The functions on `Application` are:
-
-Function | Purpose
----------|--------------
-`Errorf(format, args)` | Display a printf formatted error to the user.
-`Fatalf(format, args)` | As with Errorf, but also call the termination handler.
-`FatalUsage(format, args)` | As with Fatalf, but also print contextual usage information.
-`FatalUsageContext(context, format, args)` | As with Fatalf, but also print contextual usage information from a `ParseContext`.
-`FatalIfError(err, format, args)` | Conditionally print an error prefixed with format+args, then call the termination handler
-
-There are equivalent global functions in the kingpin namespace for the default
-`kingpin.CommandLine` instance.
-
-### Sub-commands
-
-Kingpin supports nested sub-commands, with separate flag and positional
-arguments per sub-command. Note that positional arguments may only occur after
-sub-commands.
-
-For example:
-
-```go
-var (
-  deleteCommand     = kingpin.Command("delete", "Delete an object.")
-  deleteUserCommand = deleteCommand.Command("user", "Delete a user.")
-  deleteUserUIDFlag = deleteUserCommand.Flag("uid", "Delete user by UID rather than username.")
-  deleteUserUsername = deleteUserCommand.Arg("username", "Username to delete.")
-  deletePostCommand = deleteCommand.Command("post", "Delete a post.")
-)
-
-func main() {
-  switch kingpin.Parse() {
-  case deleteUserCommand.FullCommand():
-  case deletePostCommand.FullCommand():
-  }
-}
-```
-
-### Custom Parsers
-
-Kingpin supports both flag and positional argument parsers for converting to
-Go types. For example, some included parsers are `Int()`, `Float()`,
-`Duration()` and `ExistingFile()` (see [parsers.go](./parsers.go) for a complete list of included parsers).
-
-Parsers conform to Go's [`flag.Value`](http://godoc.org/flag#Value)
-interface, so any existing implementations will work.
-
-For example, a parser for accumulating HTTP header values might look like this:
-
-```go
-type HTTPHeaderValue http.Header
-
-func (h *HTTPHeaderValue) Set(value string) error {
-  parts := strings.SplitN(value, ":", 2)
-  if len(parts) != 2 {
-    return fmt.Errorf("expected HEADER:VALUE got '%s'", value)
-  }
-  (*http.Header)(h).Add(parts[0], parts[1])
-  return nil
-}
-
-func (h *HTTPHeaderValue) String() string {
-  return ""
-}
-```
-
-As a convenience, I would recommend something like this:
-
-```go
-func HTTPHeader(s Settings) (target *http.Header) {
-  target = &http.Header{}
-  s.SetValue((*HTTPHeaderValue)(target))
-  return
-}
-```
-
-You would use it like so:
-
-```go
-headers = HTTPHeader(kingpin.Flag("header", "Add a HTTP header to the request.").Short('H'))
-```
-
-### Repeatable flags
-
-Depending on the `Value` they hold, some flags may be repeated. The
-`IsCumulative() bool` function on `Value` tells if it's safe to call `Set()`
-multiple times or if an error should be raised if several values are passed.
-
-The built-in `Value`s returning slices and maps, as well as `Counter` are
-examples of `Value`s that make a flag repeatable.
-
-### Boolean values
-
-Boolean values are uniquely managed by Kingpin. Each boolean flag will have a negative complement:
-`--<name>` and `--no-<name>`.
-
-### Default Values
-
-The default value is the zero value for a type. This can be overridden with
-the `Default(value...)` function on flags and arguments. This function accepts
-one or several strings, which are parsed by the value itself, so they *must*
-be compliant with the format expected.
-
-### Place-holders in Help
-
-The place-holder value for a flag is the value used in the help to describe
-the value of a non-boolean flag.
-
-The value provided to PlaceHolder() is used if provided, then the value
-provided by Default() if provided, then finally the capitalised flag name is
-used.
-
-Here are some examples of flags with various permutations:
-
-    --name=NAME           // Flag(...).String()
-    --name="Harry"        // Flag(...).Default("Harry").String()
-    --name=FULL-NAME      // Flag(...).PlaceHolder("FULL-NAME").Default("Harry").String()
-
-### Consuming all remaining arguments
-
-A common command-line idiom is to use all remaining arguments for some
-purpose. eg. The following command accepts an arbitrary number of
-IP addresses as positional arguments:
-
-    ./cmd ping 10.1.1.1 192.168.1.1
-
-Such arguments are similar to [repeatable flags](#repeatable-flags), but for
-arguments. Therefore they use the same `IsCumulative() bool` function on the
-underlying `Value`, so the built-in `Value`s for which the `Set()` function
-can be called several times will consume multiple arguments.
-
-To implement the above example with a custom `Value`, we might do something
-like this:
-
-```go
-type ipList []net.IP
-
-func (i *ipList) Set(value string) error {
-  if ip := net.ParseIP(value); ip == nil {
-    return fmt.Errorf("'%s' is not an IP address", value)
-  } else {
-    *i = append(*i, ip)
-    return nil
-  }
-}
-
-func (i *ipList) String() string {
-  return ""
-}
-
-func (i *ipList) IsCumulative() bool {
-  return true
-}
-
-func IPList(s Settings) (target *[]net.IP) {
-  target = new([]net.IP)
-  s.SetValue((*ipList)(target))
-  return
-}
-```
-
-And use it like so:
-
-```go
-ips := IPList(kingpin.Arg("ips", "IP addresses to ping."))
-```
-
-### Bash/ZSH Shell Completion
-
-By default, all flags and commands/subcommands generate completions
-internally.
-
-Out of the box, CLI tools using kingpin should be able to take advantage
-of completion hinting for flags and commands. By specifying
-`--completion-bash` as the first argument, your CLI tool will show
-possible subcommands. By ending your argv with `--`, hints for flags
-will be shown.
-
-To allow your end users to take advantage you must package a
-`/etc/bash_completion.d` script with your distribution (or the equivalent
-for your target platform/shell). An alternative is to instruct your end
-user to source a script from their `bash_profile` (or equivalent).
-
-Fortunately Kingpin makes it easy to generate or source a script for use
-with end users shells. `./yourtool --completion-script-bash` and
-`./yourtool --completion-script-zsh` will generate these scripts for you.
-
-**Installation by Package**
-
-For the best user experience, you should bundle your pre-created
-completion script with your CLI tool and install it inside
-`/etc/bash_completion.d` (or equivalent). A good suggestion is to add
-this as an automated step to your build pipeline, in the implementation
-is improved for bug fixed.
-
-**Installation by `bash_profile`**
-
-Alternatively, instruct your users to add an additional statement to
-their `bash_profile` (or equivalent):
-
-```
-eval "$(your-cli-tool --completion-script-bash)"
-```
-
-Or for ZSH
-
-```
-eval "$(your-cli-tool --completion-script-zsh)"
-```
-
-#### Additional API
-To provide more flexibility, a completion option API has been
-exposed for flags to allow user defined completion options, to extend
-completions further than just EnumVar/Enum.
-
-
-**Provide Static Options**
-
-When using an `Enum` or `EnumVar`, users are limited to only the options
-given. Maybe we wish to hint possible options to the user, but also
-allow them to provide their own custom option. `HintOptions` gives
-this functionality to flags.
-
-```
-app := kingpin.New("completion", "My application with bash completion.")
-app.Flag("port", "Provide a port to connect to").
-    Required().
-    HintOptions("80", "443", "8080").
-    IntVar(&c.port)
-```
-
-**Provide Dynamic Options**
-Consider the case that you needed to read a local database or a file to
-provide suggestions. You can dynamically generate the options
-
-```
-func listHosts() []string {
-  // Provide a dynamic list of hosts from a hosts file or otherwise
-  // for bash completion. In this example we simply return static slice.
-
-  // You could use this functionality to reach into a hosts file to provide
-  // completion for a list of known hosts.
-  return []string{"sshhost.example", "webhost.example", "ftphost.example"}
-}
-
-app := kingpin.New("completion", "My application with bash completion.")
-app.Flag("flag-1", "").HintAction(listHosts).String()
-```
-
-**EnumVar/Enum**
-When using `Enum` or `EnumVar`, any provided options will be automatically
-used for bash autocompletion. However, if you wish to provide a subset or
-different options, you can use `HintOptions` or `HintAction` which will override
-the default completion options for `Enum`/`EnumVar`.
-
-
-**Examples**
-You can see an in depth example of the completion API within
-`examples/completion/main.go`
-
-
-### Supporting -h for help
-
-`kingpin.CommandLine.HelpFlag.Short('h')`
-
-Short help is also available when creating a more complicated app:
-
-```go
-var (
-	app = kingpin.New("chat", "A command-line chat application.")
-  // ...
-)
-
-func main() {
-	app.HelpFlag.Short('h')
-	switch kingpin.MustParse(app.Parse(os.Args[1:])) {
-  // ...
-  }
-}
-```
-
-### Custom help
-
-Kingpin v2 supports templatised help using the text/template library (actually, [a fork](https://github.com/alecthomas/template)).
-
-You can specify the template to use with the [Application.UsageTemplate()](http://godoc.org/github.com/alecthomas/kingpin/v2#Application.UsageTemplate) function.
-
-There are four included templates: `kingpin.DefaultUsageTemplate` is the default,
-`kingpin.CompactUsageTemplate` provides a more compact representation for more complex command-line structures,
-`kingpin.SeparateOptionalFlagsUsageTemplate` looks like the default template, but splits required
-and optional command flags into separate lists, and `kingpin.ManPageTemplate` is used to generate man pages.
-
-See the above templates for examples of usage, and the the function [UsageForContextWithTemplate()](https://github.com/alecthomas/kingpin/blob/master/usage.go#L198) method for details on the context.
-
-#### Default help template
-
-```
-$ go run ./examples/curl/curl.go --help
-usage: curl [<flags>] <command> [<args> ...]
-
-An example implementation of curl.
-
-Flags:

-go-metrics
-==========
-
-This library provides a `metrics` package which can be used to instrument code,
-expose application metrics, and profile runtime performance in a flexible manner.
-
-Current API: [![GoDoc](https://godoc.org/github.com/armon/go-metrics?status.svg)](https://godoc.org/github.com/armon/go-metrics)
-
-Sinks
------
-
-The `metrics` package makes use of a `MetricSink` interface to support delivery
-to any type of backend. Currently the following sinks are provided:
-
-* StatsiteSink : Sinks to a [statsite](https://github.com/armon/statsite/) instance (TCP)
-* StatsdSink: Sinks to a [StatsD](https://github.com/etsy/statsd/) / statsite instance (UDP)
-* PrometheusSink: Sinks to a [Prometheus](http://prometheus.io/) metrics endpoint (exposed via HTTP for scrapes)
-* InmemSink : Provides in-memory aggregation, can be used to export stats
-* FanoutSink : Sinks to multiple sinks. Enables writing to multiple statsite instances for example.
-* BlackholeSink : Sinks to nowhere
-
-In addition to the sinks, the `InmemSignal` can be used to catch a signal,
-and dump a formatted output of recent metrics. For example, when a process gets
-a SIGUSR1, it can dump to stderr recent performance metrics for debugging.
-
-Labels
-------
-
-Most metrics do have an equivalent ending with `WithLabels`, such methods
-allow to push metrics with labels and use some features of underlying Sinks
-(ex: translated into Prometheus labels).
-
-Since some of these labels may increase greatly cardinality of metrics, the
-library allow to filter labels using a blacklist/whitelist filtering system
-which is global to all metrics.
-
-* If `Config.AllowedLabels` is not nil, then only labels specified in this value will be sent to underlying Sink, otherwise, all labels are sent by default.
-* If `Config.BlockedLabels` is not nil, any label specified in this value will not be sent to underlying Sinks.
-
-By default, both `Config.AllowedLabels` and `Config.BlockedLabels` are nil, meaning that
-no tags are filetered at all, but it allow to a user to globally block some tags with high
-cardinality at application level.
-
-Examples
---------
-
-Here is an example of using the package:
-
-```go
-func SlowMethod() {
-    // Profiling the runtime of a method
-    defer metrics.MeasureSince([]string{"SlowMethod"}, time.Now())
-}
-
-// Configure a statsite sink as the global metrics sink
-sink, _ := metrics.NewStatsiteSink("statsite:8125")
-metrics.NewGlobal(metrics.DefaultConfig("service-name"), sink)
-
-// Emit a Key/Value pair
-metrics.EmitKey([]string{"questions", "meaning of life"}, 42)
-```
-
-Here is an example of setting up a signal handler:
-
-```go
-// Setup the inmem sink and signal handler
-inm := metrics.NewInmemSink(10*time.Second, time.Minute)
-sig := metrics.DefaultInmemSignal(inm)
-metrics.NewGlobal(metrics.DefaultConfig("service-name"), inm)
-
-// Run some code
-inm.SetGauge([]string{"foo"}, 42)
-inm.EmitKey([]string{"bar"}, 30)
-
-inm.IncrCounter([]string{"baz"}, 42)
-inm.IncrCounter([]string{"baz"}, 1)
-inm.IncrCounter([]string{"baz"}, 80)
-
-inm.AddSample([]string{"method", "wow"}, 42)
-inm.AddSample([]string{"method", "wow"}, 100)
-inm.AddSample([]string{"method", "wow"}, 22)
-
-....
-```
-
-When a signal comes in, output like the following will be dumped to stderr:
-
-    [2014-01-28 14:57:33.04 -0800 PST][G] 'foo': 42.000
-    [2014-01-28 14:57:33.04 -0800 PST][P] 'bar': 30.000
-    [2014-01-28 14:57:33.04 -0800 PST][C] 'baz': Count: 3 Min: 1.000 Mean: 41.000 Max: 80.000 Stddev: 39.509
-    [2014-01-28 14:57:33.04 -0800 PST][S] 'method.wow': Count: 3 Min: 22.000 Mean: 54.667 Max: 100.000 Stddev: 40.513

-# Contributor Code of Conduct
-
-This project adheres to [The Code Manifesto](http://codemanifesto.com)
-as its guidelines for contributor interactions.
-
-## The Code Manifesto
-
-We want to work in an ecosystem that empowers developers to reach their
-potential — one that encourages growth and effective collaboration. A space
-that is safe for all.
-
-A space such as this benefits everyone that participates in it. It encourages
-new developers to enter our field. It is through discussion and collaboration
-that we grow, and through growth that we improve.
-
-In the effort to create such a place, we hold to these values:
-
-1. **Discrimination limits us.** This includes discrimination on the basis of
-   race, gender, sexual orientation, gender identity, age, nationality,
-   technology and any other arbitrary exclusion of a group of people.
-2. **Boundaries honor us.** Your comfort levels are not everyone’s comfort
-   levels. Remember that, and if brought to your attention, heed it.
-3. **We are our biggest assets.** None of us were born masters of our trade.
-   Each of us has been helped along the way. Return that favor, when and where
-   you can.
-4. **We are resources for the future.** As an extension of #3, share what you
-   know. Make yourself a resource to help those that come after you.
-5. **Respect defines us.** Treat others as you wish to be treated. Make your
-   discussions, criticisms and debates from a position of respectfulness. Ask
-   yourself, is it true? Is it necessary? Is it constructive? Anything less is
-   unacceptable.
-6. **Reactions require grace.** Angry responses are valid, but abusive language
-   and vindictive actions are toxic. When something happens that offends you,
-   handle it assertively, but be respectful. Escalate reasonably, and try to
-   allow the offender an opportunity to explain themselves, and possibly
-   correct the issue.
-7. **Opinions are just that: opinions.** Each and every one of us, due to our
-   background and upbringing, have varying opinions. That is perfectly
-   acceptable. Remember this: if you respect your own opinions, you should
-   respect the opinions of others.
-8. **To err is human.** You might not intend it, but mistakes do happen and
-   contribute to build experience. Tolerate honest mistakes, and don't
-   hesitate to apologize if you make one yourself.

-#### Support
-If you do have a contribution to the package, feel free to create a Pull Request or an Issue.
-
-#### What to contribute
-If you don't know what to do, there are some features and functions that need to be done
-
-- [ ] Refactor code
-- [ ] Edit docs and [README](https://github.com/asaskevich/govalidator/README.md): spellcheck, grammar and typo check
-- [ ] Create actual list of contributors and projects that currently using this package
-- [ ] Resolve [issues and bugs](https://github.com/asaskevich/govalidator/issues)
-- [ ] Update actual [list of functions](https://github.com/asaskevich/govalidator#list-of-functions)
-- [ ] Update [list of validators](https://github.com/asaskevich/govalidator#validatestruct-2) that available for `ValidateStruct` and add new
-- [ ] Implement new validators: `IsFQDN`, `IsIMEI`, `IsPostalCode`, `IsISIN`, `IsISRC` etc
-- [x] Implement [validation by maps](https://github.com/asaskevich/govalidator/issues/224)
-- [ ] Implement fuzzing testing
-- [ ] Implement some struct/map/array utilities
-- [ ] Implement map/array validation
-- [ ] Implement benchmarking
-- [ ] Implement batch of examples
-- [ ] Look at forks for new features and fixes
-
-#### Advice
-Feel free to create what you want, but keep in mind when you implement new features:
-- Code must be clear and readable, names of variables/constants clearly describes what they are doing
-- Public functions must be documented and described in source file and added to README.md to the list of available functions
-- There are must be unit-tests for any new functions and improvements
-
-## Financial contributions
-
-We also welcome financial contributions in full transparency on our [open collective](https://opencollective.com/govalidator).
-Anyone can file an expense. If the expense makes sense for the development of the community, it will be "merged" in the ledger of our open collective by the core contributors and the person who filed the expense will be reimbursed.

-After it the package is ready to use.
-
-
-#### Import package in your project
-Add following line in your `*.go` file:
-```go
-import "github.com/asaskevich/govalidator"
-```
-If you are unhappy to use long `govalidator`, you can do something like this:
-```go
-import (
-  valid "github.com/asaskevich/govalidator"
-)
-```
-
-#### Activate behavior to require all fields have a validation tag by default
-`SetFieldsRequiredByDefault` causes validation to fail when struct fields do not include validations or are not explicitly marked as exempt (using `valid:"-"` or `valid:"email,optional"`). A good place to activate this is a package init function or the main() function.
-
-`SetNilPtrAllowedByRequired` causes validation to pass when struct fields marked by `required` are set to nil. This is disabled by default for consistency, but some packages that need to be able to determine between `nil` and `zero value` state can use this. If disabled, both `nil` and `zero` values cause validation errors.
-
-```go
-import "github.com/asaskevich/govalidator"
-
-func init() {
-  govalidator.SetFieldsRequiredByDefault(true)
-}
-```
-
-Here's some code to explain it:
-```go
-// this struct definition will fail govalidator.ValidateStruct() (and the field values do not matter):
-type exampleStruct struct {
-  Name  string ``
-  Email string `valid:"email"`
-}
-
-// this, however, will only fail when Email is empty or an invalid email address:
-type exampleStruct2 struct {
-  Name  string `valid:"-"`
-  Email string `valid:"email"`
-}
-
-// lastly, this will only fail when Email is an invalid email address but not when it's empty:
-type exampleStruct2 struct {
-  Name  string `valid:"-"`
-  Email string `valid:"email,optional"`
-}
-```
-
-#### Recent breaking changes (see [#123](https://github.com/asaskevich/govalidator/pull/123))
-##### Custom validator function signature
-A context was added as the second parameter, for structs this is the object being validated – this makes dependent validation possible.
-```go
-import "github.com/asaskevich/govalidator"
-
-// old signature
-func(i interface{}) bool
-
-// new signature
-func(i interface{}, o interface{}) bool
-```
-
-##### Adding a custom validator
-This was changed to prevent data races when accessing custom validators.
-```go
-import "github.com/asaskevich/govalidator"
-
-// before
-govalidator.CustomTypeTagMap["customByteArrayValidator"] = func(i interface{}, o interface{}) bool {
-  // ...
-}
-
-// after
-govalidator.CustomTypeTagMap.Set("customByteArrayValidator", func(i interface{}, o interface{}) bool {
-  // ...
-})
-```

-#### Examples
-###### IsURL
-```go
-println(govalidator.IsURL(`http://user@pass:domain.com/path/page`))
-```
-###### IsType
-```go
-println(govalidator.IsType("Bob", "string"))
-println(govalidator.IsType(1, "int"))
-i := 1
-println(govalidator.IsType(&i, "*int"))
-```
-
-IsType can be used through the tag `type` which is essential for map validation:
-```go
-type User	struct {
-  Name string      `valid:"type(string)"`
-  Age  int         `valid:"type(int)"`
-  Meta interface{} `valid:"type(string)"`
-}
-result, err := govalidator.ValidateStruct(User{"Bob", 20, "meta"})
-if err != nil {
-	println("error: " + err.Error())
-}
-println(result)
-```
-###### ToString
-```go
-type User struct {
-	FirstName string
-	LastName string
-}
-
-str := govalidator.ToString(&User{"John", "Juan"})
-println(str)
-```
-###### Each, Map, Filter, Count for slices
-Each iterates over the slice/array and calls Iterator for every item
-```go
-data := []interface{}{1, 2, 3, 4, 5}
-var fn govalidator.Iterator = func(value interface{}, index int) {
-	println(value.(int))
-}
-govalidator.Each(data, fn)
-```
-```go
-data := []interface{}{1, 2, 3, 4, 5}
-var fn govalidator.ResultIterator = func(value interface{}, index int) interface{} {
-	return value.(int) * 3
-}
-_ = govalidator.Map(data, fn) // result = []interface{}{1, 6, 9, 12, 15}
-```
-```go
-data := []interface{}{1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
-var fn govalidator.ConditionIterator = func(value interface{}, index int) bool {
-	return value.(int)%2 == 0
-}
-_ = govalidator.Filter(data, fn) // result = []interface{}{2, 4, 6, 8, 10}
-_ = govalidator.Count(data, fn) // result = 5
-```
-###### ValidateStruct [#2](https://github.com/asaskevich/govalidator/pull/2)
-If you want to validate structs, you can use tag `valid` for any field in your structure. All validators used with this field in one tag are separated by comma. If you want to skip validation, place `-` in your tag. If you need a validator that is not on the list below, you can add it like this:
-```go
-govalidator.TagMap["duck"] = govalidator.Validator(func(str string) bool {
-	return str == "duck"
-})
-```
-For completely custom validators (interface-based), see below.
-
-Here is a list of available validators for struct fields (validator - used function):
-```go

-"base64":             IsBase64,
-"datauri":            IsDataURI,
-"ip":                 IsIP,
-"port":               IsPort,
-"ipv4":               IsIPv4,
-"ipv6":               IsIPv6,
-"dns":                IsDNSName,
-"host":               IsHost,

-"ISO3166Alpha3":      IsISO3166Alpha3,
-"ulid":               IsULID,
-```
-Validators with parameters
-
-```go
-"range(min|max)": Range,
-"length(min|max)": ByteLength,
-"runelength(min|max)": RuneLength,
-"stringlength(min|max)": StringLength,
-"matches(pattern)": StringMatches,
-"in(string1|string2|...|stringN)": IsIn,
-"rsapub(keylength)" : IsRsaPub,
-"minstringlength(int): MinStringLength,
-"maxstringlength(int): MaxStringLength,
-```
-Validators with parameters for any type
-
-```go
-"type(type)": IsType,
-```
-
-And here is small example of usage:
-```go
-type Post struct {
-	Title    string `valid:"alphanum,required"`
-	Message  string `valid:"duck,ascii"`
-	Message2 string `valid:"animal(dog)"`
-	AuthorIP string `valid:"ipv4"`
-	Date     string `valid:"-"`
-}
-post := &Post{
-	Title:   "My Example Post",
-	Message: "duck",
-	Message2: "dog",
-	AuthorIP: "123.234.54.3",
-}
-
-// Add your own struct validation tags
-govalidator.TagMap["duck"] = govalidator.Validator(func(str string) bool {
-	return str == "duck"
-})
-
-// Add your own struct validation tags with parameter
-govalidator.ParamTagMap["animal"] = govalidator.ParamValidator(func(str string, params ...string) bool {
-    species := params[0]
-    return str == species
-})
-govalidator.ParamTagRegexMap["animal"] = regexp.MustCompile("^animal\\((\\w+)\\)$")
-
-result, err := govalidator.ValidateStruct(post)
-if err != nil {
-	println("error: " + err.Error())
-}
-println(result)
-```
-###### ValidateMap [#2](https://github.com/asaskevich/govalidator/pull/338)
-If you want to validate maps, you can use the map to be validated and a validation map that contain the same tags used in ValidateStruct, both maps have to be in the form `map[string]interface{}`
-
-So here is small example of usage:
-```go
-var mapTemplate = map[string]interface{}{
-	"name":"required,alpha",
-	"family":"required,alpha",
-	"email":"required,email",
-	"cell-phone":"numeric",
-	"address":map[string]interface{}{
-		"line1":"required,alphanum",
-		"line2":"alphanum",
-		"postal-code":"numeric",
-	},
-}
-
-var inputMap = map[string]interface{}{
-	"name":"Bob",
-	"family":"Smith",
-	"email":"foo@bar.baz",
-	"address":map[string]interface{}{
-		"line1":"",
-		"line2":"",
-		"postal-code":"",
-	},
-}
-
-result, err := govalidator.ValidateMap(inputMap, mapTemplate)
-if err != nil {
-	println("error: " + err.Error())
-}
-println(result)
-```
-
-###### WhiteList
-```go
-// Remove all characters from string ignoring characters between "a" and "z"
-println(govalidator.WhiteList("a3a43a5a4a3a2a23a4a5a4a3a4", "a-z") == "aaaaaaaaaaaa")
-```
-
-###### Custom validation functions
-Custom validation using your own domain specific validators is also available - here's an example of how to use it:
-```go
-import "github.com/asaskevich/govalidator"
-
-type CustomByteArray [6]byte // custom types are supported and can be validated
-
-type StructWithCustomByteArray struct {
-  ID              CustomByteArray `valid:"customByteArrayValidator,customMinLengthValidator"` // multiple custom validators are possible as well and will be evaluated in sequence
-  Email           string          `valid:"email"`
-  CustomMinLength int             `valid:"-"`
-}
-
-govalidator.CustomTypeTagMap.Set("customByteArrayValidator", func(i interface{}, context interface{}) bool {
-  switch v := context.(type) { // you can type switch on the context interface being validated
-  case StructWithCustomByteArray:
-    // you can check and validate against some other field in the context,
-    // return early or not validate against the context at all – your choice
-  case SomeOtherType:
-    // ...
-  default:
-    // expecting some other type? Throw/panic here or continue
-  }
-
-  switch v := i.(type) { // type switch on the struct field being validated
-  case CustomByteArray:
-    for _, e := range v { // this validator checks that the byte array is not empty, i.e. not all zeroes
-      if e != 0 {
-        return true
-      }
-    }
-  }
-  return false
-})
-govalidator.CustomTypeTagMap.Set("customMinLengthValidator", func(i interface{}, context interface{}) bool {
-  switch v := context.(type) { // this validates a field against the value in another field, i.e. dependent validation
-  case StructWithCustomByteArray:
-    return len(v.ID) >= v.CustomMinLength
-  }
-  return false
-})
-```
-
-###### Loop over Error()
-By default .Error() returns all errors in a single String. To access each error you can do this:
-```go
-  if err != nil {
-    errs := err.(govalidator.Errors).Errors()
-    for _, e := range errs {
-      fmt.Println(e.Error())
-    }
-  }
-```
-
-###### Custom error messages
-Custom error messages are supported via annotations by adding the `~` separator - here's an example of how to use it:
-```go
-type Ticket struct {
-  Id        int64     `json:"id"`
-  FirstName string    `json:"firstname" valid:"required~First name is blank"`
-}
-```
