- Change the `go` keyword to `gofmt` in line 259
- Add a new function `hostPort` to the `Plugin` struct
- Modify the `hostPort` function to set the port if it is specified in the host string

 The SCP plugin copy files and artifacts to target host machine via SSH. The below pipeline configuration demonstrates simple usage:
 
 ```yaml
-pipeline:
-  scp:
-    image: appleboy/drone-scp
+- name: scp files
+  image: appleboy/drone-scp
+  settings:
     host: example.com
-    target: /home/deploy/web
-    source: release.tar.gz
-```
-
-Example configuration with custom username, password and port:
-
-```diff
-pipeline:
-  scp:
-    image: appleboy/drone-scp
-    host: example.com
-+   username: appleboy
-+   password: 12345678
-+   port: 4430
-    target: /home/deploy/web
+    username: foo
+    password: bar
+    port: 22
+    target: /var/www/deploy/${DRONE_REPO_OWNER}/${DRONE_REPO_NAME}
     source: release.tar.gz
 ```
 
 Example configuration with multiple source and target folder:
 
 ```diff
-pipeline:
-  scp:
+  - name: scp files
     image: appleboy/drone-scp
-    host: example.com
-    target:
-+     - /home/deploy/web1
-+     - /home/deploy/web2
-    source:
-+     - release_1.tar.gz
-+     - release_2.tar.gz
+    settings:
+      host: example.com
+      target:

++       - /home/deploy/web2
+      source:
++       - release_1.tar.gz
++       - release_2.tar.gz
 ```
 
 Example configuration with multiple host:
 
 ```diff
-pipeline:
-  scp:
+  - name: scp files
     image: appleboy/drone-scp
--   host: example.com
-+   host:
-+     - example1.com

++       - example1.com
++       - example2.com
+      target: /home/deploy/web
+      source: release.tar.gz
 ```
 
 Example configuration with wildcard pattern of source list:
 
 ```diff
-pipeline:
-  scp:
+  - name: scp files
     image: appleboy/drone-scp
-    host:
-      - example1.com
-      - example2.com

-    source:
--     - release/backend.tar.gz
--     - release/images.tar.gz
-+     - release/*.tar.gz
+    settings:

+      source:
+-       - release/backend.tar.gz
+-       - release/images.tar.gz
++       - release/*.tar.gz
 ```
 
 Remove target folder before copy files and artifacts to target:
 
 ```diff
-  scp:
+  - name: scp files
     image: appleboy/drone-scp
-    host: example.com
-    target: /home/deploy/web

++     rm: true
 ```
 
 Example for remove the specified number of leading path elements:
 
 ```diff
-  scp:
+  - name: scp files

-easyssh-proxy provides a simple implementation of some SSH protocol features in Go.
-
-## Feature
-
-This project is forked from [easyssh](https://github.com/hypersleep/easyssh) but add some features as the following.
-
-* [x] Support plain text of user private key.
-* [x] Support key path of user private key.
-* [x] Support Timeout for the TCP connection to establish.
-* [x] Support SSH ProxyCommand.

-Package spew implements a deep pretty printer for Go data structures to aid in
-debugging.
-
-A quick overview of the additional features spew provides over the built-in
-printing facilities for Go data types are as follows:
-
-	* Pointers are dereferenced and followed
-	* Circular data structures are detected and handled properly
-	* Custom Stringer/error interfaces are optionally invoked, including
-	  on unexported types
-	* Custom types which only implement the Stringer/error interfaces via
-	  a pointer receiver are optionally invoked when passing non-pointer
-	  variables
-	* Byte arrays and slices are dumped like the hexdump -C command which
-	  includes offsets, byte values in hex, and ASCII output (only when using
-	  Dump style)
-
-There are two different approaches spew allows for dumping Go data structures:
-
-	* Dump style which prints with newlines, customizable indentation,
-	  and additional debug information such as types and all pointer addresses
-	  used to indirect to the final value
-	* A custom Formatter interface that integrates cleanly with the standard fmt
-	  package and replaces %v, %+v, %#v, and %#+v to provide inline printing
-	  similar to the default %v while providing the additional functionality
-	  outlined above and passing unsupported format verbs such as %x and %q
-	  along to fmt
-
-Quick Start
-
-This section demonstrates how to quickly get started with spew.  See the
-sections below for further details on formatting and configuration options.
-
-To dump a variable with full newlines, indentation, type, and pointer
-information use Dump, Fdump, or Sdump:
-	spew.Dump(myVar1, myVar2, ...)
-	spew.Fdump(someWriter, myVar1, myVar2, ...)
-	str := spew.Sdump(myVar1, myVar2, ...)
-
-Alternatively, if you would prefer to use format strings with a compacted inline
-printing style, use the convenience wrappers Printf, Fprintf, etc with
-%v (most compact), %+v (adds pointer addresses), %#v (adds types), or
-%#+v (adds types and pointer addresses):
-	spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
-	spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
-	spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
-	spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
-
-Configuration Options
-
-Configuration of spew is handled by fields in the ConfigState type.  For
-convenience, all of the top-level functions use a global state available
-via the spew.Config global.
-
-It is also possible to create a ConfigState instance that provides methods
-equivalent to the top-level functions.  This allows concurrent configuration
-options.  See the ConfigState documentation for more details.
-
-The following configuration options are available:
-	* Indent
-		String to use for each indentation level for Dump functions.
-		It is a single space by default.  A popular alternative is "\t".
-
-	* MaxDepth
-		Maximum number of levels to descend into nested data structures.
-		There is no limit by default.
-
-	* DisableMethods
-		Disables invocation of error and Stringer interface methods.
-		Method invocation is enabled by default.
-
-	* DisablePointerMethods
-		Disables invocation of error and Stringer interface methods on types
-		which only accept pointer receivers from non-pointer variables.
-		Pointer method invocation is enabled by default.
-
-	* DisablePointerAddresses
-		DisablePointerAddresses specifies whether to disable the printing of
-		pointer addresses. This is useful when diffing data structures in tests.
-
-	* DisableCapacities
-		DisableCapacities specifies whether to disable the printing of
-		capacities for arrays, slices, maps and channels. This is useful when
-		diffing data structures in tests.
-
-	* ContinueOnMethod
-		Enables recursion into types after invoking error and Stringer interface
-		methods. Recursion after method invocation is disabled by default.
-
-	* SortKeys
-		Specifies map keys should be sorted before being printed. Use
-		this to have a more deterministic, diffable output.  Note that
-		only native types (bool, int, uint, floats, uintptr and string)
-		and types which implement error or Stringer interfaces are
-		supported with other types sorted according to the
-		reflect.Value.String() output which guarantees display
-		stability.  Natural map order is used by default.
-
-	* SpewKeys
-		Specifies that, as a last resort attempt, map keys should be
-		spewed to strings and sorted by those strings.  This is only
-		considered if SortKeys is true.
-
-Dump Usage
-
-Simply call spew.Dump with a list of variables you want to dump:
-
-	spew.Dump(myVar1, myVar2, ...)
-
-You may also call spew.Fdump if you would prefer to output to an arbitrary
-io.Writer.  For example, to dump to standard error:
-
-	spew.Fdump(os.Stderr, myVar1, myVar2, ...)
-
-A third option is to call spew.Sdump to get the formatted output as a string:
-
-	str := spew.Sdump(myVar1, myVar2, ...)
-
-Sample Dump Output
-
-See the Dump example for details on the setup of the types and variables being
-shown here.
-
-	(main.Foo) {
-	 unexportedField: (*main.Bar)(0xf84002e210)({
-	  flag: (main.Flag) flagTwo,
-	  data: (uintptr) <nil>
-	 }),
-	 ExportedField: (map[interface {}]interface {}) (len=1) {
-	  (string) (len=3) "one": (bool) true
-	 }
-	}
-
-Byte (and uint8) arrays and slices are displayed uniquely like the hexdump -C
-command as shown.
-	([]uint8) (len=32 cap=32) {
-	 00000000  11 12 13 14 15 16 17 18  19 1a 1b 1c 1d 1e 1f 20  |............... |
-	 00000010  21 22 23 24 25 26 27 28  29 2a 2b 2c 2d 2e 2f 30  |!"#$%&'()*+,-./0|
-	 00000020  31 32                                             |12|
-	}
-
-Custom Formatter
-
-Spew provides a custom formatter that implements the fmt.Formatter interface
-so that it integrates cleanly with standard fmt package printing functions. The
-formatter is useful for inline printing of smaller data types similar to the
-standard %v format specifier.
-
-The custom formatter only responds to the %v (most compact), %+v (adds pointer
-addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
-combinations.  Any other verbs such as %x and %q will be sent to the the
-standard fmt package for formatting.  In addition, the custom formatter ignores
-the width and precision arguments (however they will still work on the format
-specifiers not handled by the custom formatter).
-
-Custom Formatter Usage
-
-The simplest way to make use of the spew custom formatter is to call one of the
-convenience functions such as spew.Printf, spew.Println, or spew.Printf.  The
-functions have syntax you are most likely already familiar with:
-
-	spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
-	spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
-	spew.Println(myVar, myVar2)
-	spew.Fprintf(os.Stderr, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
-	spew.Fprintf(os.Stderr, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
-
-See the Index for the full list convenience functions.
-
-Sample Formatter Output
-
-Double pointer to a uint8:
-	  %v: <**>5
-	 %+v: <**>(0xf8400420d0->0xf8400420c8)5
-	 %#v: (**uint8)5
-	%#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5
-
-Pointer to circular struct with a uint8 field and a pointer to itself:
-	  %v: <*>{1 <*><shown>}
-	 %+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)<shown>}
-	 %#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)<shown>}
-	%#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)<shown>}
-
-See the Printf example for details on the setup of variables being shown
-here.
-
-Errors
-
-Since it is possible for custom Stringer/error interfaces to panic, spew
-detects them and handles them internally by printing the panic information
-inline with the output.  Since spew is intended to provide deep pretty printing
-capabilities on structures, it intentionally does not return any errors.

-NewFormatter returns a custom formatter that satisfies the fmt.Formatter

-types similar to the standard %v format specifier.
-
-The custom formatter only responds to the %v (most compact), %+v (adds pointer
-addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
-combinations.  Any other verbs such as %x and %q will be sent to the the
-standard fmt package for formatting.  In addition, the custom formatter ignores
-the width and precision arguments (however they will still work on the format
-specifiers not handled by the custom formatter).
-
-Typically this function shouldn't be called directly.  It is much easier to make
-use of the custom formatter by calling one of the convenience functions such as
-Printf, Println, or Fprintf.

-# Color [![GoDoc](http://img.shields.io/badge/go-documentation-blue.svg?style=flat-square)](http://godoc.org/github.com/fatih/color) [![Build Status](http://img.shields.io/travis/fatih/color.svg?style=flat-square)](https://travis-ci.org/fatih/color)
-
-
-
-Color lets you use colorized outputs in terms of [ANSI Escape
-Codes](http://en.wikipedia.org/wiki/ANSI_escape_code#Colors) in Go (Golang). It
-has support for Windows too! The API can be used in several ways, pick one that
-suits you.
-
-
-![Color](http://i.imgur.com/c1JI0lA.png)
-
-
-## Install
-
-```bash
-go get github.com/fatih/color
-```
-
-Note that the `vendor` folder is here for stability. Remove the folder if you
-already have the dependencies in your GOPATH.
-
-## Examples
-
-### Standard colors
-
-```go
-// Print with default helper functions
-color.Cyan("Prints text in cyan.")
-
-// A newline will be appended automatically
-color.Blue("Prints %s in blue.", "text")
-
-// These are using the default foreground colors
-color.Red("We have red")
-color.Magenta("And many others ..")
-
-```
-
-### Mix and reuse colors
-
-```go
-// Create a new color object
-c := color.New(color.FgCyan).Add(color.Underline)
-c.Println("Prints cyan text with an underline.")
-
-// Or just add them to New()
-d := color.New(color.FgCyan, color.Bold)
-d.Printf("This prints bold cyan %s\n", "too!.")
-
-// Mix up foreground and background colors, create new mixes!
-red := color.New(color.FgRed)
-
-boldRed := red.Add(color.Bold)
-boldRed.Println("This will print text in bold red.")
-
-whiteBackground := red.Add(color.BgWhite)
-whiteBackground.Println("Red text with white background.")
-```
-
-### Use your own output (io.Writer)
-
-```go
-// Use your own io.Writer output
-color.New(color.FgBlue).Fprintln(myWriter, "blue color!")
-
-blue := color.New(color.FgBlue)
-blue.Fprint(writer, "This will print text in blue.")
-```
-
-### Custom print functions (PrintFunc)
-
-```go
-// Create a custom print function for convenience
-red := color.New(color.FgRed).PrintfFunc()
-red("Warning")
-red("Error: %s", err)
-
-// Mix up multiple attributes
-notice := color.New(color.Bold, color.FgGreen).PrintlnFunc()
-notice("Don't forget this...")
-```
-
-### Custom fprint functions (FprintFunc)
-
-```go
-blue := color.New(FgBlue).FprintfFunc()
-blue(myWriter, "important notice: %s", stars)
-
-// Mix up with multiple attributes
-success := color.New(color.Bold, color.FgGreen).FprintlnFunc()
-success(myWriter, "Don't forget this...")
-```
-
-### Insert into noncolor strings (SprintFunc)
-
-```go
-// Create SprintXxx functions to mix strings with other non-colorized strings:
-yellow := color.New(color.FgYellow).SprintFunc()
-red := color.New(color.FgRed).SprintFunc()
-fmt.Printf("This is a %s and this is %s.\n", yellow("warning"), red("error"))
-
-info := color.New(color.FgWhite, color.BgGreen).SprintFunc()
-fmt.Printf("This %s rocks!\n", info("package"))
-
-// Use helper functions
-fmt.Println("This", color.RedString("warning"), "should be not neglected.")
-fmt.Printf("%v %v\n", color.GreenString("Info:"), "an important message.")
-
-// Windows supported too! Just don't forget to change the output to color.Output
-fmt.Fprintf(color.Output, "Windows support: %s", color.GreenString("PASS"))
-```
-
-### Plug into existing code
-
-```go
-// Use handy standard colors
-color.Set(color.FgYellow)
-
-fmt.Println("Existing text will now be in yellow")
-fmt.Printf("This one %s\n", "too")
-
-color.Unset() // Don't forget to unset
-
-// You can mix up parameters
-color.Set(color.FgMagenta, color.Bold)
-defer color.Unset() // Use it in your function
-
-fmt.Println("All text will now be bold magenta.")
-```
-
-### Disable color
-
-There might be a case where you want to disable color output (for example to
-pipe the standard output of your app to somewhere else). `Color` has support to
-disable colors both globally and for single color definition. For example
-suppose you have a CLI app and a `--no-color` bool flag. You can easily disable
-the color output with:
-
-```go
-
-var flagNoColor = flag.Bool("no-color", false, "Disable color output")
-
-if *flagNoColor {
-	color.NoColor = true // disables colorized output
-}
-```
-
-It also has support for single color definitions (local). You can
-disable/enable color output on the fly:
-
-```go
-c := color.New(color.FgCyan)
-c.Println("Prints cyan text")
-
-c.DisableColor()
-c.Println("This is printed without any color")
-
-c.EnableColor()
-c.Println("This prints again cyan...")
-```
-

-
-* Save/Return previous values
-* Evaluate fmt.Formatter interface

-/*
-Package color is an ANSI color package to output colorized or SGR defined
-output to the standard output. The API can be used in several way, pick one
-that suits you.
-
-Use simple and default helper functions with predefined foreground colors:
-
-    color.Cyan("Prints text in cyan.")
-
-    // a newline will be appended automatically
-    color.Blue("Prints %s in blue.", "text")
-
-    // More default foreground colors..
-    color.Red("We have red")
-    color.Yellow("Yellow color too!")
-    color.Magenta("And many others ..")
-
-However there are times where custom color mixes are required. Below are some
-examples to create custom color objects and use the print functions of each
-separate color object.
-
-    // Create a new color object
-    c := color.New(color.FgCyan).Add(color.Underline)
-    c.Println("Prints cyan text with an underline.")
-
-    // Or just add them to New()
-    d := color.New(color.FgCyan, color.Bold)
-    d.Printf("This prints bold cyan %s\n", "too!.")
-
-
-    // Mix up foreground and background colors, create new mixes!
-    red := color.New(color.FgRed)
-
-    boldRed := red.Add(color.Bold)
-    boldRed.Println("This will print text in bold red.")
-
-    whiteBackground := red.Add(color.BgWhite)
-    whiteBackground.Println("Red text with White background.")
-
-    // Use your own io.Writer output
-    color.New(color.FgBlue).Fprintln(myWriter, "blue color!")
-
-    blue := color.New(color.FgBlue)
-    blue.Fprint(myWriter, "This will print text in blue.")
-
-You can create PrintXxx functions to simplify even more:
-
-    // Create a custom print function for convenient
-    red := color.New(color.FgRed).PrintfFunc()
-    red("warning")
-    red("error: %s", err)
-
-    // Mix up multiple attributes
-    notice := color.New(color.Bold, color.FgGreen).PrintlnFunc()
-    notice("don't forget this...")
-
-You can also FprintXxx functions to pass your own io.Writer:
-
-    blue := color.New(FgBlue).FprintfFunc()
-    blue(myWriter, "important notice: %s", stars)
-
-    // Mix up with multiple attributes
-    success := color.New(color.Bold, color.FgGreen).FprintlnFunc()
-    success(myWriter, don't forget this...")
-
-
-Or create SprintXxx functions to mix strings with other non-colorized strings:
-
-    yellow := New(FgYellow).SprintFunc()
-    red := New(FgRed).SprintFunc()
-
-    fmt.Printf("this is a %s and this is %s.\n", yellow("warning"), red("error"))
-
-    info := New(FgWhite, BgGreen).SprintFunc()
-    fmt.Printf("this %s rocks!\n", info("package"))
-
-Windows support is enabled by default. All Print functions works as intended.
-However only for color.SprintXXX functions, user should use fmt.FprintXXX and
-set the output to color.Output:
-
-    fmt.Fprintf(color.Output, "Windows support: %s", color.GreenString("PASS"))
-
-    info := New(FgWhite, BgGreen).SprintFunc()
-    fmt.Fprintf(color.Output, "this %s rocks!\n", info("package"))
-
-Using with existing code is possible. Just use the Set() method to set the
-standard output to the given parameters. That way a rewrite of an existing
-code is not required.
-
-    // Use handy standard colors.
-    color.Set(color.FgYellow)
-
-    fmt.Println("Existing text will be now in Yellow")
-    fmt.Printf("This one %s\n", "too")
-
-    color.Unset() // don't forget to unset
-
-    // You can mix up parameters
-    color.Set(color.FgMagenta, color.Bold)
-    defer color.Unset() // use it in your function
-
-    fmt.Println("All text will be now bold magenta.")
-
-There might be a case where you want to disable color output (for example to
-pipe the standard output of your app to somewhere else). `Color` has support to
-disable colors both globally and for single color definition. For example
-suppose you have a CLI app and a `--no-color` bool flag. You can easily disable
-the color output with:
-
-    var flagNoColor = flag.Bool("no-color", false, "Disable color output")
-
-    if *flagNoColor {
-    	color.NoColor = true // disables colorized output
-    }
-
-It also has support for single color definitions (local). You can
-disable/enable color output on the fly:
-
-     c := color.New(color.FgCyan)
-     c.Println("Prints cyan text")
-
-     c.DisableColor()
-     c.Println("This is printed without any color")
-
-     c.EnableColor()
-     c.Println("This prints again cyan...")

-# GoDotEnv [![wercker status](https://app.wercker.com/status/507594c2ec7e60f19403a568dfea0f78 "wercker status")](https://app.wercker.com/project/bykey/507594c2ec7e60f19403a568dfea0f78)
-
-A Go (golang) port of the Ruby dotenv project (which loads env vars from a .env file)
-
-From the original Library:
-
-> Storing configuration in the environment is one of the tenets of a twelve-factor app. Anything that is likely to change between deployment environments–such as resource handles for databases or credentials for external services–should be extracted from the code into environment variables.
->
-> But it is not always practical to set environment variables on development machines or continuous integration servers where multiple projects are run. Dotenv load variables from a .env file into ENV when the environment is bootstrapped.
-
-It can be used as a library (for loading in env for your own daemons etc) or as a bin command.
-
-There is test coverage and CI for both linuxish and windows environments, but I make no guarantees about the bin version working on windows.
-
-## Installation
-
-As a library
-
-```shell
-go get github.com/joho/godotenv
-```
-
-or if you want to use it as a bin command
-```shell
-go get github.com/joho/godotenv/cmd/godotenv
-```
-
-## Usage
-
-Add your application configuration to your `.env` file in the root of your project:
-
-```shell
-S3_BUCKET=YOURS3BUCKET
-SECRET_KEY=YOURSECRETKEYGOESHERE
-```
-
-Then in your Go app you can do something like
-
-```go
-package main
-
-import (
-    "github.com/joho/godotenv"
-    "log"
-    "os"
-)
-
-func main() {
-  err := godotenv.Load()
-  if err != nil {
-    log.Fatal("Error loading .env file")
-  }
-
-  s3Bucket := os.Getenv("S3_BUCKET")
-  secretKey := os.Getenv("SECRET_KEY")
-
-  // now do something with s3 or whatever
-}
-```
-
-If you're even lazier than that, you can just take advantage of the autoload package which will read in `.env` on import
-
-```go
-import _ "github.com/joho/godotenv/autoload"
-```
-
-While `.env` in the project root is the default, you don't have to be constrained, both examples below are 100% legit
-
-```go
-_ = godotenv.Load("somerandomfile")
-_ = godotenv.Load("filenumberone.env", "filenumbertwo.env")
-```
-
-If you want to be really fancy with your env file you can do comments and exports (below is a valid env file)
-
-```shell
-# I am a comment and that is OK
-SOME_VAR=someval
-FOO=BAR # comments at line end are OK too
-export BAR=BAZ
-```
-
-Or finally you can do YAML(ish) style
-
-```yaml
-FOO: bar
-BAR: baz
-```
-
-as a final aside, if you don't want godotenv munging your env you can just get a map back instead
-
-```go
-var myEnv map[string]string
-myEnv, err := godotenv.Read()
-
-s3Bucket := myEnv["S3_BUCKET"]
-```
-
-### Command Mode
-
-Assuming you've installed the command as above and you've got `$GOPATH/bin` in your `$PATH`
-
-```
-godotenv -f /some/path/to/.env some_command with some args
-```
-
-If you don't specify `-f` it will fall back on the default of loading `.env` in `PWD`
-
-## Contributing
-
-Contributions are most welcome! The parser itself is pretty stupidly naive and I wouldn't be surprised if it breaks with edge cases.
-
-*code changes without tests will not be accepted*
-
-1. Fork it

-## Who?
-
-The original library [dotenv](https://github.com/bkeepers/dotenv) was written by [Brandon Keepers](http://opensoul.org/), and this port was done by [John Barton](http://whoisjohnbarton.com) based off the tests/fixtures in the original library.

-Colorable writer for windows.
-
-For example, most of logger packages doesn't show colors on windows. (I know we can do it with ansicon. But I don't want.)
-This package is possible to handle escape sequence for ansi color on windows.

-// SequenceMatcher compares sequence of strings. The basic
-// algorithm predates, and is a little fancier than, an algorithm
-// published in the late 1980's by Ratcliff and Obershelp under the
-// hyperbolic name "gestalt pattern matching".  The basic idea is to find
-// the longest contiguous matching subsequence that contains no "junk"
-// elements (R-O doesn't address junk).  The same idea is then applied
-// recursively to the pieces of the sequences to the left and to the right
-// of the matching subsequence.  This does not yield minimal edit
-// sequences, but does tend to yield matches that "look right" to people.
-//
-// SequenceMatcher tries to compute a "human-friendly diff" between two
-// sequences.  Unlike e.g. UNIX(tm) diff, the fundamental notion is the
-// longest *contiguous* & junk-free matching subsequence.  That's what
-// catches peoples' eyes.  The Windows(tm) windiff has another interesting
-// notion, pairing up elements that appear uniquely in each sequence.
-// That, and the method here, appear to yield more intuitive difference
-// reports than does diff.  This method appears to be the least vulnerable
-// to synching up on blocks of "junk lines", though (like blank lines in
-// ordinary text files, or maybe "<P>" lines in HTML files).  That may be
-// because this is the only method of the 3 that has a *concept* of
-// "junk" <wink>.
-//
-// Timing:  Basic R-O is cubic time worst case and quadratic time expected
-// case.  SequenceMatcher is quadratic time for the worst case and has
-// expected-case behavior dependent in a complicated way on how many
-// elements the sequences have in common; best case time is linear.

-// Package assert provides a set of comprehensive testing tools for use with the normal Go testing system.
-//
-// Example Usage
-//
-// The following is a complete example using assert in a standard test function:
-//    import (
-//      "testing"
-//      "github.com/stretchr/testify/assert"
-//    )
-//
-//    func TestSomething(t *testing.T) {
-//
-//      var a string = "Hello"
-//      var b string = "Hello"
-//
-//      assert.Equal(t, a, b, "The two words should be the same.")
-//
-//    }
-//
-// if you assert many times, use the format below:
-//
-//    import (
-//      "testing"
-//      "github.com/stretchr/testify/assert"
-//    )
-//
-//    func TestSomething(t *testing.T) {
-//      assert := assert.New(t)
-//
-//      var a string = "Hello"
-//      var b string = "Hello"
-//
-//      assert.Equal(a, b, "The two words should be the same.")
-//    }
-//
-// Assertions
-//
-// Assertions allow you to easily write test code, and are global funcs in the `assert` package.
-// All assertion functions take, as the first argument, the `*testing.T` object provided by the
-// testing framework. This allows the assertion funcs to write the failings and other details to
-// the correct place.
-//
-// Every assertion function also takes an optional string message as the final argument,
-// allowing custom error messages to be appended to the message the assertion method outputs.

-# Change Log
-
-**ATTN**: This project uses [semantic versioning](http://semver.org/).
-
-## [Unreleased]
-
-## [1.19.1] - 2016-11-21
-
-### Fixed
-
-- Fixes regression introduced in 1.19.0 where using an `ActionFunc` as
-  the `Action` for a command would cause it to error rather than calling the
-  function. Should not have a affected declarative cases using `func(c
-  *cli.Context) err)`.
-- Shell completion now handles the case where the user specifies
-  `--generate-bash-completion` immediately after a flag that takes an argument.
-  Previously it call the application with `--generate-bash-completion` as the
-  flag value.
-
-## [1.19.0] - 2016-11-19
-### Added
-- `FlagsByName` was added to make it easy to sort flags (e.g. `sort.Sort(cli.FlagsByName(app.Flags))`)
-- A `Description` field was added to `App` for a more detailed description of
-  the application (similar to the existing `Description` field on `Command`)
-- Flag type code generation via `go generate`
-- Write to stderr and exit 1 if action returns non-nil error
-- Added support for TOML to the `altsrc` loader
-- `SkipArgReorder` was added to allow users to skip the argument reordering.
-  This is useful if you want to consider all "flags" after an argument as
-  arguments rather than flags (the default behavior of the stdlib `flag`
-  library). This is backported functionality from the [removal of the flag
-  reordering](https://github.com/urfave/cli/pull/398) in the unreleased version
-  2
-- For formatted errors (those implementing `ErrorFormatter`), the errors will
-  be formatted during output. Compatible with `pkg/errors`.
-
-### Changed
-- Raise minimum tested/supported Go version to 1.2+
-
-### Fixed
-- Consider empty environment variables as set (previously environment variables
-  with the equivalent of `""` would be skipped rather than their value used).
-- Return an error if the value in a given environment variable cannot be parsed
-  as the flag type. Previously these errors were silently swallowed.
-- Print full error when an invalid flag is specified (which includes the invalid flag)
-- `App.Writer` defaults to `stdout` when `nil`
-- If no action is specified on a command or app, the help is now printed instead of `panic`ing
-- `App.Metadata` is initialized automatically now (previously was `nil` unless initialized)
-- Correctly show help message if `-h` is provided to a subcommand
-- `context.(Global)IsSet` now respects environment variables. Previously it
-  would return `false` if a flag was specified in the environment rather than
-  as an argument
-- Removed deprecation warnings to STDERR to avoid them leaking to the end-user
-- `altsrc`s import paths were updated to use `gopkg.in/urfave/cli.v1`. This
-  fixes issues that occurred when `gopkg.in/urfave/cli.v1` was imported as well
-  as `altsrc` where Go would complain that the types didn't match
-
-## [1.18.1] - 2016-08-28
-### Fixed
-- Removed deprecation warnings to STDERR to avoid them leaking to the end-user (backported)
-
-## [1.18.0] - 2016-06-27
-### Added
-- `./runtests` test runner with coverage tracking by default
-- testing on OS X
-- testing on Windows
-- `UintFlag`, `Uint64Flag`, and `Int64Flag` types and supporting code
-
-### Changed
-- Use spaces for alignment in help/usage output instead of tabs, making the
-  output alignment consistent regardless of tab width
-
-### Fixed
-- Printing of command aliases in help text
-- Printing of visible flags for both struct and struct pointer flags
-- Display the `help` subcommand when using `CommandCategories`
-- No longer swallows `panic`s that occur within the `Action`s themselves when
-  detecting the signature of the `Action` field
-
-## [1.17.1] - 2016-08-28
-### Fixed
-- Removed deprecation warnings to STDERR to avoid them leaking to the end-user
-
-## [1.17.0] - 2016-05-09
-### Added
-- Pluggable flag-level help text rendering via `cli.DefaultFlagStringFunc`
-- `context.GlobalBoolT` was added as an analogue to `context.GlobalBool`
-- Support for hiding commands by setting `Hidden: true` -- this will hide the
-  commands in help output
-
-### Changed
-- `Float64Flag`, `IntFlag`, and `DurationFlag` default values are no longer
-  quoted in help text output.
-- All flag types now include `(default: {value})` strings following usage when a
-  default value can be (reasonably) detected.
-- `IntSliceFlag` and `StringSliceFlag` usage strings are now more consistent
-  with non-slice flag types
-- Apps now exit with a code of 3 if an unknown subcommand is specified
-  (previously they printed "No help topic for...", but still exited 0. This
-  makes it easier to script around apps built using `cli` since they can trust
-  that a 0 exit code indicated a successful execution.
-- cleanups based on [Go Report Card
-  feedback](https://goreportcard.com/report/github.com/urfave/cli)
-
-## [1.16.1] - 2016-08-28
-### Fixed
-- Removed deprecation warnings to STDERR to avoid them leaking to the end-user
-
-## [1.16.0] - 2016-05-02
-### Added
-- `Hidden` field on all flag struct types to omit from generated help text
-
-### Changed
-- `BashCompletionFlag` (`--enable-bash-completion`) is now omitted from
-generated help text via the `Hidden` field
-
-### Fixed
-- handling of error values in `HandleAction` and `HandleExitCoder`
-
-## [1.15.0] - 2016-04-30
-### Added
-- This file!
-- Support for placeholders in flag usage strings
-- `App.Metadata` map for arbitrary data/state management
-- `Set` and `GlobalSet` methods on `*cli.Context` for altering values after
-parsing.
-- Support for nested lookup of dot-delimited keys in structures loaded from
-YAML.
-
-### Changed
-- The `App.Action` and `Command.Action` now prefer a return signature of
-`func(*cli.Context) error`, as defined by `cli.ActionFunc`.  If a non-nil
-`error` is returned, there may be two outcomes:
-    - If the error fulfills `cli.ExitCoder`, then `os.Exit` will be called
-    automatically
-    - Else the error is bubbled up and returned from `App.Run`
-- Specifying an `Action` with the legacy return signature of
-`func(*cli.Context)` will produce a deprecation message to stderr
-- Specifying an `Action` that is not a `func` type will produce a non-zero exit
-from `App.Run`
-- Specifying an `Action` func that has an invalid (input) signature will
-produce a non-zero exit from `App.Run`
-
-### Deprecated
-- <a name="deprecated-cli-app-runandexitonerror"></a>
-`cli.App.RunAndExitOnError`, which should now be done by returning an error
-that fulfills `cli.ExitCoder` to `cli.App.Run`.
-- <a name="deprecated-cli-app-action-signature"></a> the legacy signature for
-`cli.App.Action` of `func(*cli.Context)`, which should now have a return
-signature of `func(*cli.Context) error`, as defined by `cli.ActionFunc`.
-
-### Fixed
-- Added missing `*cli.Context.GlobalFloat64` method
-
-## [1.14.0] - 2016-04-03 (backfilled 2016-04-25)
-### Added

-
-### Changed

-
-### Fixed

-#!/usr/bin/env python
-"""
-The flag types that ship with the cli library have many things in common, and
-so we can take advantage of the `go generate` command to create much of the
-source code from a list of definitions.  These definitions attempt to cover
-the parts that vary between flag types, and should evolve as needed.
-
-An example of the minimum definition needed is:
-
-    {
-      "name": "SomeType",
-      "type": "sometype",
-      "context_default": "nil"
-    }
-
-In this example, the code generated for the `cli` package will include a type
-named `SomeTypeFlag` that is expected to wrap a value of type `sometype`.
-Fetching values by name via `*cli.Context` will default to a value of `nil`.
-
-A more complete, albeit somewhat redundant, example showing all available
-definition keys is:
-
-    {
-      "name": "VeryMuchType",
-      "type": "*VeryMuchType",
-      "value": true,
-      "dest": false,
-      "doctail": " which really only wraps a []float64, oh well!",
-      "context_type": "[]float64",
-      "context_default": "nil",
-      "parser": "parseVeryMuchType(f.Value.String())",
-      "parser_cast": "[]float64(parsed)"
-    }
-
-The meaning of each field is as follows:
-
-               name (string) - The type "name", which will be suffixed with
-                               `Flag` when generating the type definition
-                               for `cli` and the wrapper type for `altsrc`
-               type (string) - The type that the generated `Flag` type for `cli`
-                               is expected to "contain" as its `.Value` member
-                value (bool) - Should the generated `cli` type have a `Value`
-                               member?
-                 dest (bool) - Should the generated `cli` type support a
-                               destination pointer?
-            doctail (string) - Additional docs for the `cli` flag type comment
-       context_type (string) - The literal type used in the `*cli.Context`
-                               reader func signature
-    context_default (string) - The literal value used as the default by the
-                               `*cli.Context` reader funcs when no value is
-                               present
-             parser (string) - Literal code used to parse the flag `f`,
-                               expected to have a return signature of
-                               (value, error)
-        parser_cast (string) - Literal code used to cast the `parsed` value
-                               returned from the `parser` code
