+Use this  plugin for publishing files and artifacts to GitHub releases. You
+can override the default configuration with the following parameters:
+
+* `api_key` - GitHub oauth token with public_repo or repo permission
+* `files` - Files to upload to GitHub Release, globs are allowed
+* `file_exists` - What to do if an file asset already exists, supported values: **overwrite** (default), **skip** and **fail**
+* `checksum` - Checksum takes hash methods to include in your GitHub release for the files specified. Supported hash methods include md5, sha1, sha256, sha512, adler32, and crc32.
+* `draft` - create a draft release if set to true
+* `base_url` - GitHub base URL, only required for GHE
+* `upload_url` - GitHub upload URL, only required for GHE
+
+Sample configuration:
+
+```yaml
+publish:
+  github_release:
+    api_key: my_github_api_key
+    files: dist/*
+    checksum: sha1
+```
+
+or
+
+```yaml
+publish:
+  github_release:
+    api_key: my_github_api_key
+    files:
+      - dist/*
+      - bin/binary.exe
+    checksum:
+      - md5
+      - sha1
+      - sha256
+      - sha512
+      - adler32
+      - crc32
+```

-# Logrus <img src="http://i.imgur.com/hTeVwmJ.png" width="40" height="40" alt=":walrus:" class="emoji" title=":walrus:"/>&nbsp;[![Build Status](https://travis-ci.org/Sirupsen/logrus.svg?branch=master)](https://travis-ci.org/Sirupsen/logrus)&nbsp;[![godoc reference](https://godoc.org/github.com/Sirupsen/logrus?status.png)][godoc]
-
-Logrus is a structured logger for Go (golang), completely API compatible with
-the standard library logger. [Godoc][godoc]. **Please note the Logrus API is not
-yet stable (pre 1.0). Logrus itself is completely stable and has been used in
-many large deployments. The core API is unlikely to change much but please
-version control your Logrus to make sure you aren't fetching latest `master` on
-every build.**
-
-Nicely color-coded in development (when a TTY is attached, otherwise just
-plain text):
-
-![Colored](http://i.imgur.com/PY7qMwd.png)
-
-With `log.Formatter = new(logrus.JSONFormatter)`, for easy parsing by logstash
-or Splunk:
-
-```json
-{"animal":"walrus","level":"info","msg":"A group of walrus emerges from the
-ocean","size":10,"time":"2014-03-10 19:57:38.562264131 -0400 EDT"}
-
-{"level":"warning","msg":"The group's number increased tremendously!",
-"number":122,"omg":true,"time":"2014-03-10 19:57:38.562471297 -0400 EDT"}
-
-{"animal":"walrus","level":"info","msg":"A giant walrus appears!",
-"size":10,"time":"2014-03-10 19:57:38.562500591 -0400 EDT"}

-"time":"2014-03-10 19:57:38.562543128 -0400 EDT"}
-```
-
-With the default `log.Formatter = new(&log.TextFormatter{})` when a TTY is not
-attached, the output is compatible with the
-[logfmt](http://godoc.org/github.com/kr/logfmt) format:

-
-#### Example
-
-The simplest way to use Logrus is simply the package-level exported logger:
-
-```go
-package main
-
-import (
-  log "github.com/Sirupsen/logrus"
-)
-
-func main() {
-  log.WithFields(log.Fields{
-    "animal": "walrus",
-  }).Info("A walrus appears")
-}
-```
-
-Note that it's completely api-compatible with the stdlib logger, so you can
-replace your `log` imports everywhere with `log "github.com/Sirupsen/logrus"`
-and you'll now have the flexibility of Logrus. You can customize it all you
-want:
-
-```go
-package main
-
-import (
-  "os"
-  log "github.com/Sirupsen/logrus"
-  "github.com/Sirupsen/logrus/hooks/airbrake"
-)
-
-func init() {
-  // Log as JSON instead of the default ASCII formatter.
-  log.SetFormatter(&log.JSONFormatter{})
-
-  // Use the Airbrake hook to report errors that have Error severity or above to
-  // an exception tracker. You can create custom hooks, see the Hooks section.
-  log.AddHook(airbrake.NewHook("https://example.com", "xyz", "development"))
-
-  // Output to stderr instead of stdout, could also be a file.
-  log.SetOutput(os.Stderr)
-
-  // Only log the warning severity or above.
-  log.SetLevel(log.WarnLevel)
-}
-
-func main() {
-  log.WithFields(log.Fields{
-    "animal": "walrus",
-    "size":   10,
-  }).Info("A group of walrus emerges from the ocean")
-
-  log.WithFields(log.Fields{
-    "omg":    true,
-    "number": 122,
-  }).Warn("The group's number increased tremendously!")
-
-  log.WithFields(log.Fields{
-    "omg":    true,
-    "number": 100,
-  }).Fatal("The ice breaks!")
-
-  // A common pattern is to re-use fields between logging statements by re-using
-  // the logrus.Entry returned from WithFields()
-  contextLogger := log.WithFields(log.Fields{
-    "common": "this is a common field",
-    "other": "I also should be logged always",
-  })
-
-  contextLogger.Info("I'll be logged with common and other field")
-  contextLogger.Info("Me too")
-}
-```
-
-For more advanced usage such as logging to multiple locations from the same
-application, you can also create an instance of the `logrus` Logger:
-
-```go
-package main
-
-import (
-  "github.com/Sirupsen/logrus"
-)
-
-// Create a new instance of the logger. You can have any number of instances.
-var log = logrus.New()
-
-func main() {
-  // The API for setting attributes is a little different than the package level
-  // exported logger. See Godoc.
-  log.Out = os.Stderr
-
-  log.WithFields(logrus.Fields{
-    "animal": "walrus",
-    "size":   10,
-  }).Info("A group of walrus emerges from the ocean")
-}
-```
-
-#### Fields
-
-Logrus encourages careful, structured logging though logging fields instead of
-long, unparseable error messages. For example, instead of: `log.Fatalf("Failed
-to send event %s to topic %s with key %d")`, you should log the much more
-discoverable:
-
-```go
-log.WithFields(log.Fields{
-  "event": event,
-  "topic": topic,
-  "key": key,
-}).Fatal("Failed to send event")
-```
-
-We've found this API forces you to think about logging in a way that produces
-much more useful logging messages. We've been in countless situations where just
-a single added field to a log statement that was already there would've saved us
-hours. The `WithFields` call is optional.
-
-In general, with Logrus using any of the `printf`-family functions should be
-seen as a hint you should add a field, however, you can still use the
-`printf`-family functions with Logrus.
-
-#### Hooks
-
-You can add hooks for logging levels. For example to send errors to an exception
-tracking service on `Error`, `Fatal` and `Panic`, info to StatsD or log to
-multiple places simultaneously, e.g. syslog.
-
-Logrus comes with [built-in hooks](hooks/). Add those, or your custom hook, in
-`init`:
-
-```go
-import (
-  log "github.com/Sirupsen/logrus"
-  "github.com/Sirupsen/logrus/hooks/airbrake"
-  logrus_syslog "github.com/Sirupsen/logrus/hooks/syslog"
-  "log/syslog"
-)
-
-func init() {
-  log.AddHook(airbrake.NewHook("https://example.com", "xyz", "development"))
-
-  hook, err := logrus_syslog.NewSyslogHook("udp", "localhost:514", syslog.LOG_INFO, "")
-  if err != nil {
-    log.Error("Unable to connect to local syslog daemon")
-  } else {
-    log.AddHook(hook)
-  }
-}
-```
-

-
-#### Level logging
-
-Logrus has six logging levels: Debug, Info, Warning, Error, Fatal and Panic.
-
-```go
-log.Debug("Useful debugging information.")
-log.Info("Something noteworthy happened!")
-log.Warn("You should probably take a look at this.")
-log.Error("Something failed but I'm not quitting.")
-// Calls os.Exit(1) after logging
-log.Fatal("Bye.")
-// Calls panic() after logging
-log.Panic("I'm bailing.")
-```
-
-You can set the logging level on a `Logger`, then it will only log entries with
-that severity or anything above it:
-
-```go
-// Will log anything that is info or above (warn, error, fatal, panic). Default.
-log.SetLevel(log.InfoLevel)
-```
-
-It may be useful to set `log.Level = logrus.DebugLevel` in a debug or verbose
-environment if your application has that.
-
-#### Entries
-
-Besides the fields added with `WithField` or `WithFields` some fields are
-automatically added to all logging events:
-
-1. `time`. The timestamp when the entry was created.
-2. `msg`. The logging message passed to `{Info,Warn,Error,Fatal,Panic}` after
-   the `AddFields` call. E.g. `Failed to send event.`
-3. `level`. The logging level. E.g. `info`.
-
-#### Environments
-
-Logrus has no notion of environment.
-
-If you wish for hooks and formatters to only be used in specific environments,
-you should handle that yourself. For example, if your application has a global
-variable `Environment`, which is a string representation of the environment you
-could do:
-
-```go
-import (
-  log "github.com/Sirupsen/logrus"
-)
-
-init() {
-  // do something here to set environment depending on an environment variable
-  // or command-line flag
-  if Environment == "production" {
-    log.SetFormatter(&log.JSONFormatter{})
-  } else {
-    // The TextFormatter is default, you don't actually have to do this.
-    log.SetFormatter(&log.TextFormatter{})
-  }
-}
-```
-
-This configuration is how `logrus` was intended to be used, but JSON in
-production is mostly only useful if you do log aggregation with tools like
-Splunk or Logstash.
-
-#### Formatters
-
-The built-in logging formatters are:
-
-* `logrus.TextFormatter`. Logs the event in colors if stdout is a tty, otherwise
-  without colors.
-  * *Note:* to force colored output when there is no TTY, set the `ForceColors`
-    field to `true`.  To force no colored output even if there is a TTY  set the
-    `DisableColors` field to `true`
-* `logrus.JSONFormatter`. Logs fields as JSON.
-* `logrus_logstash.LogstashFormatter`. Logs fields as Logstash Events (http://logstash.net).
-
-    ```go
-      logrus.SetFormatter(&logrus_logstash.LogstashFormatter{Type: “application_name"})
-    ```
-
-Third party logging formatters:
-
-* [`zalgo`](https://github.com/aybabtme/logzalgo): invoking the P͉̫o̳̼̊w̖͈̰͎e̬͔̭͂r͚̼̹̲ ̫͓͉̳͈ō̠͕͖̚f̝͍̠ ͕̲̞͖͑Z̖̫̤̫ͪa͉̬͈̗l͖͎g̳̥o̰̥̅!̣͔̲̻͊̄ ̙̘̦̹̦.
-
-You can define your formatter by implementing the `Formatter` interface,
-requiring a `Format` method. `Format` takes an `*Entry`. `entry.Data` is a
-`Fields` type (`map[string]interface{}`) with all your fields as well as the
-default ones (see Entries section above):
-
-```go
-type MyJSONFormatter struct {
-}
-
-log.SetFormatter(new(MyJSONFormatter))
-
-func (f *MyJSONFormatter) Format(entry *Entry) ([]byte, error) {
-  // Note this doesn't include Time, Level and Message which are available on
-  // the Entry. Consult `godoc` on information about those fields or read the
-  // source of the official loggers.
-  serialized, err := json.Marshal(entry.Data)
-    if err != nil {
-      return nil, fmt.Errorf("Failed to marshal fields to JSON, %v", err)
-    }
-  return append(serialized, '\n'), nil
-}
-```
-
-#### Logger as an `io.Writer`
-
-Logrus can be transformed into an `io.Writer`. That writer is the end of an `io.Pipe` and it is your responsibility to close it.
-
-```go
-w := logger.Writer()
-defer w.Close()
-
-srv := http.Server{
-    // create a stdlib log.Logger that writes to
-    // logrus.Logger.
-    ErrorLog: log.New(w, "", 0),
-}
-```
-
-Each line written to that writer will be printed the usual way, using formatters
-and hooks. The level for those entries is `info`.
-
-#### Rotation
-
-Log rotation is not provided with Logrus. Log rotation should be done by an
-external program (like `logrotate(8)`) that can compress and delete old log
-entries. It should not be a feature of the application-level logger.

+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions

+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the

+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+# Go support for Protocol Buffers
+
+Google's data interchange format.
+Copyright 2010 The Go Authors.
+https://github.com/golang/protobuf
+
+This package and the code it generates requires at least Go 1.4.
+
+This software implements Go bindings for protocol buffers.  For
+information about protocol buffers themselves, see
+	https://developers.google.com/protocol-buffers/
+
+## Installation ##
+
+To use this software, you must:
+- Install the standard C++ implementation of protocol buffers from
+	https://developers.google.com/protocol-buffers/
+- Of course, install the Go compiler and tools from
+	https://golang.org/
+  See
+	https://golang.org/doc/install
+  for details or, if you are using gccgo, follow the instructions at
+	https://golang.org/doc/install/gccgo
+- Grab the code from the repository and install the proto package.
+  The simplest way is to run `go get -u github.com/golang/protobuf/{proto,protoc-gen-go}`.
+  The compiler plugin, protoc-gen-go, will be installed in $GOBIN,
+  defaulting to $GOPATH/bin.  It must be in your $PATH for the protocol
+  compiler, protoc, to find it.
+
+This software has two parts: a 'protocol compiler plugin' that
+generates Go source files that, once compiled, can access and manage
+protocol buffers; and a library that implements run-time support for
+encoding (marshaling), decoding (unmarshaling), and accessing protocol
+buffers.
+
+There is support for gRPC in Go using protocol buffers.
+See the note at the bottom of this file for details.
+
+There are no insertion points in the plugin.
+
+
+## Using protocol buffers with Go ##
+
+Once the software is installed, there are two steps to using it.
+First you must compile the protocol buffer definitions and then import
+them, with the support library, into your program.
+
+To compile the protocol buffer definition, run protoc with the --go_out
+parameter set to the directory you want to output the Go code to.
+
+	protoc --go_out=. *.proto
+
+The generated files will be suffixed .pb.go.  See the Test code below
+for an example using such a file.
+
+
+The package comment for the proto library contains text describing
+the interface provided in Go for protocol buffers. Here is an edited
+version.
+
+==========
+
+The proto package converts data structures to and from the
+wire format of protocol buffers.  It works in concert with the
+Go source code generated for .proto files by the protocol compiler.
+
+A summary of the properties of the protocol buffer interface
+for a protocol buffer variable v:
+
+  - Names are turned from camel_case to CamelCase for export.
+  - There are no methods on v to set fields; just treat
+  	them as structure fields.
+  - There are getters that return a field's value if set,
+	and return the field's default value if unset.
+	The getters work even if the receiver is a nil message.
+  - The zero value for a struct is its correct initialization state.
+	All desired fields must be set before marshaling.
+  - A Reset() method will restore a protobuf struct to its zero state.
+  - Non-repeated fields are pointers to the values; nil means unset.
+	That is, optional or required field int32 f becomes F *int32.
+  - Repeated fields are slices.
+  - Helper functions are available to aid the setting of fields.
+	Helpers for getting values are superseded by the
+	GetFoo methods and their use is deprecated.
+		msg.Foo = proto.String("hello") // set field
+  - Constants are defined to hold the default values of all fields that
+	have them.  They have the form Default_StructName_FieldName.
+	Because the getter methods handle defaulted values,
+	direct use of these constants should be rare.
+  - Enums are given type names and maps from names to values.
+	Enum values are prefixed with the enum's type name. Enum types have
+	a String method, and a Enum method to assist in message construction.
+  - Nested groups and enums have type names prefixed with the name of
+  	the surrounding message type.
+  - Extensions are given descriptor names that start with E_,
+	followed by an underscore-delimited list of the nested messages
+	that contain it (if any) followed by the CamelCased name of the
+	extension field itself.  HasExtension, ClearExtension, GetExtension
+	and SetExtension are functions for manipulating extensions.
+  - Oneof field sets are given a single field in their message,
+	with distinguished wrapper types for each possible field value.
+  - Marshal and Unmarshal are functions to encode and decode the wire format.
+
+When the .proto file specifies `syntax="proto3"`, there are some differences:
+
+  - Non-repeated fields of non-message type are values instead of pointers.
+  - Getters are only generated for message and oneof fields.
+  - Enum types do not get an Enum method.
+
+Consider file test.proto, containing
+
+```proto
+	package example;
+	
+	enum FOO { X = 17; };
+	
+	message Test {
+	  required string label = 1;
+	  optional int32 type = 2 [default=77];
+	  repeated int64 reps = 3;
+	  optional group OptionalGroup = 4 {
+	    required string RequiredField = 5;
+	  }
+	}
+```
+
+To create and play with a Test object from the example package,
+
+```go
+	package main
+
+	import (
+		"log"
+
+		"github.com/golang/protobuf/proto"
+		"path/to/example"
+	)
+
+	func main() {
+		test := &example.Test {
+			Label: proto.String("hello"),
+			Type:  proto.Int32(17),
+			Reps:  []int64{1, 2, 3},
+			Optionalgroup: &example.Test_OptionalGroup {
+				RequiredField: proto.String("good bye"),
+			},
+		}
+		data, err := proto.Marshal(test)
+		if err != nil {
+			log.Fatal("marshaling error: ", err)
+		}
+		newTest := &example.Test{}
+		err = proto.Unmarshal(data, newTest)
+		if err != nil {
+			log.Fatal("unmarshaling error: ", err)
+		}
+		// Now test and newTest contain the same data.
+		if test.GetLabel() != newTest.GetLabel() {
+			log.Fatalf("data mismatch %q != %q", test.GetLabel(), newTest.GetLabel())
+		}
+		// etc.
+	}
+```
+
+## Parameters ##
+
+To pass extra parameters to the plugin, use a comma-separated
+parameter list separated from the output directory by a colon:
+
+
+	protoc --go_out=plugins=grpc,import_path=mypackage:. *.proto
+
+
+- `import_prefix=xxx` - a prefix that is added onto the beginning of
+  all imports. Useful for things like generating protos in a
+  subdirectory, or regenerating vendored protobufs in-place.
+- `import_path=foo/bar` - used as the package if no input files
+  declare `go_package`. If it contains slashes, everything up to the
+  rightmost slash is ignored.
+- `plugins=plugin1+plugin2` - specifies the list of sub-plugins to
+  load. The only plugin in this repo is `grpc`.
+- `Mfoo/bar.proto=quux/shme` - declares that foo/bar.proto is
+  associated with Go package quux/shme.  This is subject to the
+  import_prefix parameter.
+
+## gRPC Support ##
+
+If a proto file specifies RPC services, protoc-gen-go can be instructed to
+generate code compatible with gRPC (http://www.grpc.io/). To do this, pass
+the `plugins` parameter to protoc-gen-go; the usual way is to insert it into
+the --go_out argument to protoc:
+
+	protoc --go_out=plugins=grpc:. *.proto
+
+## Plugins ##
+
+The `protoc-gen-go/generator` package exposes a plugin interface,
+which is used by the gRPC code generation. This interface is not
+supported and is subject to incompatible changes without notice.

+Equal returns true iff protocol buffers a and b are equal.
+The arguments must both be pointers to protocol buffer structs.

+Equality is defined in this way:
+  - Two messages are equal iff they are the same type,
+    corresponding fields are equal, unknown field sets
+    are equal, and extensions sets are equal.
+  - Two set scalar fields are equal iff their values are equal.
+    If the fields are of a floating-point type, remember that
+    NaN != x for all x, including NaN. If the message is defined
+    in a proto3 .proto file, fields are not "set"; specifically,
+    zero length proto3 "bytes" fields are equal (nil == {}).
+  - Two repeated fields are equal iff their lengths are the same,
+    and their corresponding elements are equal (a "bytes" field,
+    although represented by []byte, is not a repeated field)
+  - Two unset fields are equal.
+  - Two unknown field sets are equal if their current
+    encoded state is equal.
+  - Two extension sets are equal iff they have corresponding
+    elements that are pairwise equal.
+  - Every other combination of things are not equal.

+Package proto converts data structures to and from the wire format of
+protocol buffers.  It works in concert with the Go source code generated
+for .proto files by the protocol compiler.
+
+A summary of the properties of the protocol buffer interface
+for a protocol buffer variable v:
+
+  - Names are turned from camel_case to CamelCase for export.
+  - There are no methods on v to set fields; just treat
+	them as structure fields.
+  - There are getters that return a field's value if set,
+	and return the field's default value if unset.
+	The getters work even if the receiver is a nil message.
+  - The zero value for a struct is its correct initialization state.
+	All desired fields must be set before marshaling.
+  - A Reset() method will restore a protobuf struct to its zero state.
+  - Non-repeated fields are pointers to the values; nil means unset.
+	That is, optional or required field int32 f becomes F *int32.
+  - Repeated fields are slices.
+  - Helper functions are available to aid the setting of fields.
+	msg.Foo = proto.String("hello") // set field
+  - Constants are defined to hold the default values of all fields that
+	have them.  They have the form Default_StructName_FieldName.
+	Because the getter methods handle defaulted values,
+	direct use of these constants should be rare.
+  - Enums are given type names and maps from names to values.
+	Enum values are prefixed by the enclosing message's name, or by the
+	enum's type name if it is a top-level enum. Enum types have a String
+	method, and a Enum method to assist in message construction.
+  - Nested messages, groups and enums have type names prefixed with the name of
+	the surrounding message type.
+  - Extensions are given descriptor names that start with E_,
+	followed by an underscore-delimited list of the nested messages
+	that contain it (if any) followed by the CamelCased name of the
+	extension field itself.  HasExtension, ClearExtension, GetExtension
+	and SetExtension are functions for manipulating extensions.
+  - Oneof field sets are given a single field in their message,
+	with distinguished wrapper types for each possible field value.
+  - Marshal and Unmarshal are functions to encode and decode the wire format.
+
+When the .proto file specifies `syntax="proto3"`, there are some differences:
+
+  - Non-repeated fields of non-message type are values instead of pointers.
+  - Getters are only generated for message and oneof fields.
+  - Enum types do not get an Enum method.
+
+The simplest way to describe this is to see an example.
+Given file test.proto, containing
+
+	package example;
+
+	enum FOO { X = 17; }
+
+	message Test {
+	  required string label = 1;
+	  optional int32 type = 2 [default=77];
+	  repeated int64 reps = 3;
+	  optional group OptionalGroup = 4 {
+	    required string RequiredField = 5;
