+# Logrus [![Build Status](https://travis-ci.org/sirupsen/logrus.svg?branch=master)](https://travis-ci.org/sirupsen/logrus) [![GoDoc](https://godoc.org/github.com/sirupsen/logrus?status.svg)](https://godoc.org/github.com/sirupsen/logrus)
+
+Logrus is a structured logger for Go (golang), completely API compatible with
+the standard library logger.
+
+**Seeing weird case-sensitive problems?** It's in the past been possible to
+import Logrus as both upper- and lower-case. Due to the Go package environment,
+this caused issues in the community and we needed a standard. Some environments
+experienced problems with the upper-case variant, so the lower-case was decided.
+Everything using `logrus` will need to use the lower-case:
+`github.com/sirupsen/logrus`. Any package that isn't, should be changed.
+
+To fix Glide, see [these
+comments](https://github.com/sirupsen/logrus/issues/553#issuecomment-306591437).
+For an in-depth explanation of the casing issue, see [this
+comment](https://github.com/sirupsen/logrus/issues/570#issuecomment-313933276).
+
+**Are you interested in assisting in maintaining Logrus?** Currently I have a
+lot of obligations, and I am unable to provide Logrus with the maintainership it
+needs. If you'd like to help, please reach out to me at `simon at author's
+username dot com`.
+
+Nicely color-coded in development (when a TTY is attached, otherwise just
+plain text):
+
+![Colored](http://i.imgur.com/PY7qMwd.png)
+
+With `log.SetFormatter(&log.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"}
+
+{"animal":"walrus","level":"info","msg":"Tremendously sized cow enters the ocean.",
+"size":9,"time":"2014-03-10 19:57:38.562527896 -0400 EDT"}
+
+{"level":"fatal","msg":"The ice breaks!","number":100,"omg":true,
+"time":"2014-03-10 19:57:38.562543128 -0400 EDT"}
+```
+
+With the default `log.SetFormatter(&log.TextFormatter{})` when a TTY is not
+attached, the output is compatible with the
+[logfmt](http://godoc.org/github.com/kr/logfmt) format:
+
+```text
+time="2015-03-26T01:27:38-04:00" level=debug msg="Started observing beach" animal=walrus number=8
+time="2015-03-26T01:27:38-04:00" level=info msg="A group of walrus emerges from the ocean" animal=walrus size=10
+time="2015-03-26T01:27:38-04:00" level=warning msg="The group's number increased tremendously!" number=122 omg=true
+time="2015-03-26T01:27:38-04:00" level=debug msg="Temperature changes" temperature=-4
+time="2015-03-26T01:27:38-04:00" level=panic msg="It's over 9000!" animal=orca size=9009
+time="2015-03-26T01:27:38-04:00" level=fatal msg="The ice breaks!" err=&{0x2082280c0 map[animal:orca size:9009] 2015-03-26 01:27:38.441574009 -0400 EDT panic It's over 9000!} number=100 omg=true
+```
+To ensure this behaviour even if a TTY is attached, set your formatter as follows:
+
+```go
+ log.SetFormatter(&log.TextFormatter{
+ DisableColors: true,
+ FullTimestamp: true,
+ })
+```
+
+#### Logging Method Name
+
+If you wish to add the calling method as a field, instruct the logger via:
+```go
+log.SetReportCaller(true)
+```
+This adds the caller as 'method' like so:
+
+```json
+{"animal":"penguin","level":"fatal","method":"github.com/sirupsen/arcticcreatures.migrate","msg":"a penguin swims by",
+"time":"2014-03-10 19:57:38.562543129 -0400 EDT"}
+```
+
+```text
+time="2015-03-26T01:27:38-04:00" level=fatal method=github.com/sirupsen/arcticcreatures.migrate msg="a penguin swims by" animal=penguin
+```
+Note that this does add measurable overhead - the cost will depend on the version of Go, but is
+between 20 and 40% in recent tests with 1.6 and 1.7. You can validate this in your
+environment via benchmarks:
+```
+go test -bench=.*CallerTracing
+```
+
+
+#### Case-sensitivity
+
+The organization's name was changed to lower-case--and this will not be changed
+back. If you are getting import conflicts due to case sensitivity, please use
+the lower-case import: `github.com/sirupsen/logrus`.
+
+#### 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"
+)
+
+func init() {
+ // Log as JSON instead of the default ASCII formatter.
+ log.SetFormatter(&log.JSONFormatter{})
+
+ // Output to stdout instead of the default stderr
+ // Can be any io.Writer, see below for File example
+ log.SetOutput(os.Stdout)
+
+ // 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 (
+ "os"
+ "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.Stdout
+
+ // You could set this to any `io.Writer` such as a file
+ // file, err := os.OpenFile("logrus.log", os.O_CREATE|os.O_WRONLY, 0666)
+ // if err == nil {
+ // log.Out = file
+ // } else {
+ // log.Info("Failed to log to file, using default stderr")
+ // }
+
+ log.WithFields(logrus.Fields{
+ "animal": "walrus",
+ "size": 10,
+ }).Info("A group of walrus emerges from the ocean")
+}
+```
+
+#### Fields
+
+Logrus encourages careful, structured logging through 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.
+
+#### Default Fields
+
+Often it's helpful to have fields _always_ attached to log statements in an
+application or parts of one. For example, you may want to always log the
+`request_id` and `user_ip` in the context of a request. Instead of writing
+`log.WithFields(log.Fields{"request_id": request_id, "user_ip": user_ip})` on
+every line, you can create a `logrus.Entry` to pass around instead:
+
+```go
+requestLogger := log.WithFields(log.Fields{"request_id": request_id, "user_ip": user_ip})
+requestLogger.Info("something happened on that request") # will log request_id and user_ip
+requestLogger.Warn("something not great happened")
+```
+
+#### 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"
+ "gopkg.in/gemnasium/logrus-airbrake-hook.v2" // the package is named "airbrake"
+ logrus_syslog "github.com/sirupsen/logrus/hooks/syslog"
+ "log/syslog"
+)
+
+func init() {
+
+ // 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(123, "xyz", "production"))
+
+ 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)
+ }
+}
+```
+Note: Syslog hook also support connecting to local syslog (Ex. "/dev/log" or "/var/run/syslog" or "/var/run/log"). For the detail, please check the [syslog hook README](hooks/syslog/README.md).
+
+A list of currently known of service hook can be found in this wiki [page](https://github.com/sirupsen/logrus/wiki/Hooks)
+
+
+#### Level logging
+
+Logrus has seven logging levels: Trace, Debug, Info, Warning, Error, Fatal and Panic.
+
+```go
+log.Trace("Something very low level.")
+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`. For Windows, see
+ [github.com/mattn/go-colorable](https://github.com/mattn/go-colorable).
+ * When colors are enabled, levels are truncated to 4 characters by default. To disable
+ truncation set the `DisableLevelTruncation` field to `true`.
+ * All options are listed in the [generated docs](https://godoc.org/github.com/sirupsen/logrus#TextFormatter).
+* `logrus.JSONFormatter`. Logs fields as JSON.
+ * All options are listed in the [generated docs](https://godoc.org/github.com/sirupsen/logrus#JSONFormatter).
+
+Third party logging formatters:
+
+* [`FluentdFormatter`](https://github.com/joonix/log). Formats entries that can be parsed by Kubernetes and Google Container Engine.
+* [`GELF`](https://github.com/fabienm/go-logrus-formatters). Formats entries so they comply to Graylog's [GELF 1.1 specification](http://docs.graylog.org/en/2.4/pages/gelf.html).
+* [`logstash`](https://github.com/bshuster-repo/logrus-logstash-hook). Logs fields as [Logstash](http://logstash.net) Events.
+* [`prefixed`](https://github.com/x-cray/logrus-prefixed-formatter). Displays log entry source along with alternative layout.
+* [`zalgo`](https://github.com/aybabtme/logzalgo). Invoking the P͉̫o̳̼̊w̖͈̰͎e̬͔̭͂r͚̼̹̲ ̫͓͉̳͈ō̠͕͖̚f̝͍̠ ͕̲̞͖͑Z̖̫̤̫ͪa͉̬͈̗l͖͎g̳̥o̰̥̅!̣͔̲̻͊̄ ̙̘̦̹̦.
+* [`nested-logrus-formatter`](https://github.com/antonfisher/nested-logrus-formatter). Converts logrus fields to a nested structure.
+
+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`.
+
+This means that we can override the standard library logger easily:
+
+```go
+logger := logrus.New()
+logger.Formatter = &logrus.JSONFormatter{}
+
+// Use logrus for standard log output
+// Note that `log` here references stdlib's log
+// Not logrus imported under the name `log`.
+log.SetOutput(logger.Writer())
+```
+
+#### 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.
+
+#### Tools
+
+| Tool | Description |
+| ---- | ----------- |
+|[Logrus Mate](https://github.com/gogap/logrus_mate)|Logrus mate is a tool for Logrus to manage loggers, you can initial logger's level, hook and formatter by config file, the logger will generated with different config at different environment.|
+|[Logrus Viper Helper](https://github.com/heirko/go-contrib/tree/master/logrusHelper)|An Helper around Logrus to wrap with spf13/Viper to load configuration with fangs! And to simplify Logrus configuration use some behavior of [Logrus Mate](https://github.com/gogap/logrus_mate). [sample](https://github.com/heirko/iris-contrib/blob/master/middleware/logrus-logger/example) |
+
+#### Testing
+
+Logrus has a built in facility for asserting the presence of log messages. This is implemented through the `test` hook and provides:
+
+* decorators for existing logger (`test.NewLocal` and `test.NewGlobal`) which basically just add the `test` hook
+* a test logger (`test.NewNullLogger`) that just records log messages (and does not output any):
+
+```go
+import(
+ "github.com/sirupsen/logrus"
+ "github.com/sirupsen/logrus/hooks/test"
+ "github.com/stretchr/testify/assert"
+ "testing"
+)
+
+func TestSomething(t*testing.T){
+ logger, hook := test.NewNullLogger()
+ logger.Error("Helloerror")
+
+ assert.Equal(t, 1, len(hook.Entries))
+ assert.Equal(t, logrus.ErrorLevel, hook.LastEntry().Level)
+ assert.Equal(t, "Helloerror", hook.LastEntry().Message)
+
+ hook.Reset()
+ assert.Nil(t, hook.LastEntry())
+}
+```
+
+#### Fatal handlers
+
+Logrus can register one or more functions that will be called when any `fatal`
+level message is logged. The registered handlers will be executed before
+logrus performs a `os.Exit(1)`. This behavior may be helpful if callers need
+to gracefully shutdown. Unlike a `panic("Something went wrong...")` call which can be intercepted with a deferred `recover` a call to `os.Exit(1)` can not be intercepted.
+
+```
+...
+handler := func() {
+ // gracefully shutdown something...
+}
+logrus.RegisterExitHandler(handler)
+...
+```
+
+#### Thread safety
+
+By default, Logger is protected by a mutex for concurrent writes. The mutex is held when calling hooks and writing logs.
+If you are sure such locking is not needed, you can call logger.SetNoLock() to disable the locking.
+
+Situation when locking is not needed includes:
+
+* You have no hooks registered, or hooks calling is already thread-safe.
+
+* Writing to logger.Out is already thread-safe, for example:
+
+ 1) logger.Out is protected by locks.
+
+ 2) logger.Out is a os.File handler opened with `O_APPEND` flag, and every write is smaller than 4k. (This allow multi-thread/multi-process writing)
+

+# Humane Units [![Build Status](https://travis-ci.org/dustin/go-humanize.svg?branch=master)](https://travis-ci.org/dustin/go-humanize) [![GoDoc](https://godoc.org/github.com/dustin/go-humanize?status.svg)](https://godoc.org/github.com/dustin/go-humanize)
+
+Just a few functions for helping humanize times and sizes.
+
+`go get` it as `github.com/dustin/go-humanize`, import it as
+`"github.com/dustin/go-humanize"`, use it as `humanize`.
+
+See [godoc](https://godoc.org/github.com/dustin/go-humanize) for
+complete documentation.
+
+## Sizes
+
+This lets you take numbers like `82854982` and convert them to useful
+strings like, `83 MB` or `79 MiB` (whichever you prefer).
+
+Example:
+
+```go
+fmt.Printf("That file is %s.", humanize.Bytes(82854982)) // That file is 83 MB.
+```
+
+## Times
+
+This lets you take a `time.Time` and spit it out in relative terms.
+For example, `12 seconds ago` or `3 days from now`.
+
+Example:
+
+```go
+fmt.Printf("This was touched %s.", humanize.Time(someTimeInstance)) // This was touched 7 hours ago.
+```
+
+Thanks to Kyle Lemons for the time implementation from an IRC
+conversation one day. It's pretty neat.
+
+## Ordinals
+
+From a [mailing list discussion][odisc] where a user wanted to be able
+to label ordinals.
+
+ 0 -> 0th
+ 1 -> 1st
+ 2 -> 2nd
+ 3 -> 3rd
+ 4 -> 4th
+ [...]
+
+Example:
+
+```go
+fmt.Printf("You're my %s best friend.", humanize.Ordinal(193)) // You are my 193rd best friend.
+```
+
+## Commas
+
+Want to shove commas into numbers? Be my guest.
+
+ 0 -> 0
+ 100 -> 100
+ 1000 -> 1,000
+ 1000000000 -> 1,000,000,000
+ -100000 -> -100,000
+
+Example:
+
+```go
+fmt.Printf("You owe $%s.\n", humanize.Comma(6582491)) // You owe $6,582,491.
+```
+
+## Ftoa
+
+Nicer float64 formatter that removes trailing zeros.
+
+```go
+fmt.Printf("%f", 2.24) // 2.240000
+fmt.Printf("%s", humanize.Ftoa(2.24)) // 2.24
+fmt.Printf("%f", 2.0) // 2.000000
+fmt.Printf("%s", humanize.Ftoa(2.0)) // 2
+```
+
+## SI notation
+
+Format numbers with [SI notation][sinotation].
+
+Example:
+
+```go
+humanize.SI(0.00000000223, "M") // 2.23 nM
+```
+
+## English-specific functions
+
+The following functions are in the `humanize/english` subpackage.
+
+### Plurals
+
+Simple English pluralization
+
+```go
+english.PluralWord(1, "object", "") // object
+english.PluralWord(42, "object", "") // objects
+english.PluralWord(2, "bus", "") // buses
+english.PluralWord(99, "locus", "loci") // loci
+
+english.Plural(1, "object", "") // 1 object
+english.Plural(42, "object", "") // 42 objects
+english.Plural(2, "bus", "") // 2 buses
+english.Plural(99, "locus", "loci") // 99 loci
+```
+
+### Word series
+
+Format comma-separated words lists with conjuctions:
+
+```go
+english.WordSeries([]string{"foo"}, "and") // foo
+english.WordSeries([]string{"foo", "bar"}, "and") // foo and bar
+english.WordSeries([]string{"foo", "bar", "baz"}, "and") // foo, bar and baz
+
+english.OxfordWordSeries([]string{"foo", "bar", "baz"}, "and") // foo, bar, and baz
+```

+# YAML support for the Go language
+
+Introduction
+------------
+
+The yaml package enables Go programs to comfortably encode and decode YAML
+values. It was developed within [Canonical](https://www.canonical.com) as
+part of the [juju](https://juju.ubuntu.com) project, and is based on a
+pure Go port of the well-known [libyaml](http://pyyaml.org/wiki/LibYAML)
+C library to parse and generate YAML data quickly and reliably.
+
+Compatibility
+-------------
+
+The yaml package supports most of YAML 1.1 and 1.2, including support for
+anchors, tags, map merging, etc. Multi-document unmarshalling is not yet
+implemented, and base-60 floats from YAML 1.1 are purposefully not
+supported since they're a poor design and are gone in YAML 1.2.
+
+Installation and usage
+----------------------
+
+The import path for the package is *gopkg.in/yaml.v2*.
+
+To install it, run:
+
+ go get gopkg.in/yaml.v2
+
+API documentation
+-----------------
+
+If opened in a browser, the import path itself leads to the API documentation:
+
+ * [https://gopkg.in/yaml.v2](https://gopkg.in/yaml.v2)
+
+API stability
+-------------
+
+The package API for yaml v2 will remain stable as described in [gopkg.in](https://gopkg.in).
+
+
+License
+-------
+
+The yaml package is licensed under the Apache License 2.0. Please see the LICENSE file for details.
+
+
+Example
+-------
+
+```Go
+package main
+
+import (
+ "fmt"
+ "log"
+
+ "gopkg.in/yaml.v2"
+)
+
+var data = `
+a: Easy!
+b:
+ c: 2
+ d: [3, 4]
+`
+
+// Note: struct fields must be public in order for unmarshal to
+// correctly populate the data.
+type T struct {
+ A string
+ B struct {
+ RenamedC int `yaml:"c"`
+ D []int `yaml:",flow"`
+ }
+}
+
+func main() {
+ t := T{}
+
+ err := yaml.Unmarshal([]byte(data), &t)
+ if err != nil {
+ log.Fatalf("error: %v", err)
+ }
+ fmt.Printf("--- t:\n%v\n\n", t)
+
+ d, err := yaml.Marshal(&t)
+ if err != nil {
+ log.Fatalf("error: %v", err)
+ }
+ fmt.Printf("--- t dump:\n%s\n\n", string(d))
+
+ m := make(map[interface{}]interface{})
+
+ err = yaml.Unmarshal([]byte(data), &m)
+ if err != nil {
+ log.Fatalf("error: %v", err)
+ }
+ fmt.Printf("--- m:\n%v\n\n", m)
+
+ d, err = yaml.Marshal(&m)
+ if err != nil {
+ log.Fatalf("error: %v", err)
+ }
+ fmt.Printf("--- m dump:\n%s\n\n", string(d))
+}
+```
+
+This example will generate the following output:
+
+```
+--- t:
+{Easy! {2 [3 4]}}
+
+--- t dump:
+a: Easy!
+b:
+ c: 2
+ d: [3, 4]
+
+
+--- m:
+map[a:Easy! b:map[c:2 d:[3 4]]]
+
+--- m dump:
+a: Easy!
+b:
+ c: 2
+ d:
+ - 3
+ - 4
+```

+
+// Introduction
+// ************
+//
+// The following notes assume that you are familiar with the YAML specification
+// (http://yaml.org/spec/1.2/spec.html). We mostly follow it, although in
+// some cases we are less restrictive that it requires.
+//
+// The process of transforming a YAML stream into a sequence of events is
+// divided on two steps: Scanning and Parsing.
+//
+// The Scanner transforms the input stream into a sequence of tokens, while the
+// parser transform the sequence of tokens produced by the Scanner into a
+// sequence of parsing events.
+//
+// The Scanner is rather clever and complicated. The Parser, on the contrary,
+// is a straightforward implementation of a recursive-descendant parser (or,
+// LL(1) parser, as it is usually called).
+//
+// Actually there are two issues of Scanning that might be called "clever", the
+// rest is quite straightforward. The issues are "block collection start" and
+// "simple keys". Both issues are explained below in details.
+//
+// Here the Scanning step is explained and implemented. We start with the list
+// of all the tokens produced by the Scanner together with short descriptions.
+//
+// Now, tokens:
+//
+// STREAM-START(encoding) # The stream start.
+// STREAM-END # The stream end.
+// VERSION-DIRECTIVE(major,minor) # The '%YAML' directive.
+// TAG-DIRECTIVE(handle,prefix) # The '%TAG' directive.
+// DOCUMENT-START # '---'
+// DOCUMENT-END # '...'
+// BLOCK-SEQUENCE-START # Indentation increase denoting a block
+// BLOCK-MAPPING-START # sequence or a block mapping.
+// BLOCK-END # Indentation decrease.
+// FLOW-SEQUENCE-START # '['
+// FLOW-SEQUENCE-END # ']'
+// BLOCK-SEQUENCE-START # '{'
+// BLOCK-SEQUENCE-END # '}'
+// BLOCK-ENTRY # '-'
+// FLOW-ENTRY # ','
+// KEY # '?' or nothing (simple keys).
+// VALUE # ':'
+// ALIAS(anchor) # '*anchor'
+// ANCHOR(anchor) # '&anchor'
+// TAG(handle,suffix) # '!handle!suffix'
+// SCALAR(value,style) # A scalar.
+//
+// The following two tokens are "virtual" tokens denoting the beginning and the
+// end of the stream:
+//
+// STREAM-START(encoding)
+// STREAM-END
+//
+// We pass the information about the input stream encoding with the
+// STREAM-START token.
+//
+// The next two tokens are responsible for tags:
+//
+// VERSION-DIRECTIVE(major,minor)
+// TAG-DIRECTIVE(handle,prefix)
+//
+// Example:
+//
+// %YAML 1.1
+// %TAG ! !foo
+// %TAG !yaml! tag:yaml.org,2002:
+// ---
+//
+// The correspoding sequence of tokens:
+//
+// STREAM-START(utf-8)
+// VERSION-DIRECTIVE(1,1)
+// TAG-DIRECTIVE("!","!foo")
+// TAG-DIRECTIVE("!yaml","tag:yaml.org,2002:")
+// DOCUMENT-START
+// STREAM-END
+//
+// Note that the VERSION-DIRECTIVE and TAG-DIRECTIVE tokens occupy a whole
+// line.
+//
+// The document start and end indicators are represented by:
+//
+// DOCUMENT-START
+// DOCUMENT-END
+//
+// Note that if a YAML stream contains an implicit document (without '---'
+// and '...' indicators), no DOCUMENT-START and DOCUMENT-END tokens will be
+// produced.
+//
+// In the following examples, we present whole documents together with the
+// produced tokens.
+//
+// 1. An implicit document:
+//
+// 'a scalar'
+//
+// Tokens:
+//
+// STREAM-START(utf-8)
+// SCALAR("a scalar",single-quoted)
+// STREAM-END
+//
+// 2. An explicit document:
+//
+// ---
+// 'a scalar'
+// ...
+//
+// Tokens:
+//
+// STREAM-START(utf-8)
+// DOCUMENT-START
+// SCALAR("a scalar",single-quoted)
+// DOCUMENT-END
+// STREAM-END
+//
+// 3. Several documents in a stream:
+//
+// 'a scalar'
+// ---
+// 'another scalar'
+// ---
+// 'yet another scalar'
+//
+// Tokens:
+//
+// STREAM-START(utf-8)
+// SCALAR("a scalar",single-quoted)
+// DOCUMENT-START
+// SCALAR("another scalar",single-quoted)
+// DOCUMENT-START
+// SCALAR("yet another scalar",single-quoted)
+// STREAM-END
+//
+// We have already introduced the SCALAR token above. The following tokens are
+// used to describe aliases, anchors, tag, and scalars:
+//
+// ALIAS(anchor)
+// ANCHOR(anchor)
+// TAG(handle,suffix)
+// SCALAR(value,style)
+//
+// The following series of examples illustrate the usage of these tokens:
+//
+// 1. A recursive sequence:
+//
+// &A [ *A ]
+//
+// Tokens:
+//
+// STREAM-START(utf-8)
+// ANCHOR("A")
+// FLOW-SEQUENCE-START
+// ALIAS("A")
+// FLOW-SEQUENCE-END
+// STREAM-END
+//
+// 2. A tagged scalar:
+//
+// !!float "3.14" # A good approximation.
+//

+// 3. Various scalar styles:
+//
+// --- # Implicit empty plain scalars do not produce tokens.
+// --- a plain scalar
+// --- 'a single-quoted scalar'
+// --- "a double-quoted scalar"
+// --- |-
+// a literal scalar
+// --- >-
+// a folded
+// scalar
+//
+// Tokens:

+// STREAM-START(utf-8)
+// DOCUMENT-START
+// DOCUMENT-START
+// SCALAR("a plain scalar",plain)

+//
+// Now it's time to review collection-related tokens. We will start with
+// flow collections:
+//
+// FLOW-SEQUENCE-START
+// FLOW-SEQUENCE-END
+// FLOW-MAPPING-START
+// FLOW-MAPPING-END
+// FLOW-ENTRY
+// KEY
+// VALUE
+//
+// The tokens FLOW-SEQUENCE-START, FLOW-SEQUENCE-END, FLOW-MAPPING-START, and
+// FLOW-MAPPING-END represent the indicators '[', ']', '{', and '}'
+// correspondingly. FLOW-ENTRY represent the ',' indicator. Finally the
+// indicators '?' and ':', which are used for denoting mapping keys and values,
+// are represented by the KEY and VALUE tokens.
+//
+// The following examples show flow collections:
+//
+// 1. A flow sequence:
+//
+// [item 1, item 2, item 3]
+//
+// Tokens:
+//
+// STREAM-START(utf-8)
+// FLOW-SEQUENCE-START
+// SCALAR("item 1",plain)
+// FLOW-ENTRY
+// SCALAR("item 2",plain)
+// FLOW-ENTRY
+// SCALAR("item 3",plain)
+// FLOW-SEQUENCE-END
+// STREAM-END
+//
+// 2. A flow mapping:
+//
+// {
+// a simple key: a value, # Note that the KEY token is produced.
+// ? a complex key: another value,
+// }
+//
+// Tokens:
+//
+// STREAM-START(utf-8)
+// FLOW-MAPPING-START
+// KEY
+// SCALAR("a simple key",plain)
+// VALUE
+// SCALAR("a value",plain)
+// FLOW-ENTRY
+// KEY
+// SCALAR("a complex key",plain)
+// VALUE
+// SCALAR("another value",plain)
+// FLOW-ENTRY
+// FLOW-MAPPING-END
+// STREAM-END
+//
+// A simple key is a key which is not denoted by the '?' indicator. Note that
+// the Scanner still produce the KEY token whenever it encounters a simple key.
+//
+// For scanning block collections, the following tokens are used (note that we
+// repeat KEY and VALUE here):
+//
+// BLOCK-SEQUENCE-START
+// BLOCK-MAPPING-START
+// BLOCK-END
+// BLOCK-ENTRY
+// KEY
+// VALUE
+//
+// The tokens BLOCK-SEQUENCE-START and BLOCK-MAPPING-START denote indentation
+// increase that precedes a block collection (cf. the INDENT token in Python).
+// The token BLOCK-END denote indentation decrease that ends a block collection
+// (cf. the DEDENT token in Python). However YAML has some syntax pecularities
+// that makes detections of these tokens more complex.
+//
+// The tokens BLOCK-ENTRY, KEY, and VALUE are used to represent the indicators
+// '-', '?', and ':' correspondingly.
+//
+// The following examples show how the tokens BLOCK-SEQUENCE-START,
+// BLOCK-MAPPING-START, and BLOCK-END are emitted by the Scanner:
+//
+// 1. Block sequences:
+//
+// - item 1
+// - item 2
+// -
+// - item 3.1
+// - item 3.2
+// -
+// key 1: value 1
+// key 2: value 2
+//
+// Tokens:
+//
+// STREAM-START(utf-8)
+// BLOCK-SEQUENCE-START
+// BLOCK-ENTRY
+// SCALAR("item 1",plain)
+// BLOCK-ENTRY
+// SCALAR("item 2",plain)
+// BLOCK-ENTRY
+// BLOCK-SEQUENCE-START
+// BLOCK-ENTRY
+// SCALAR("item 3.1",plain)
+// BLOCK-ENTRY
+// SCALAR("item 3.2",plain)
+// BLOCK-END
+// BLOCK-ENTRY
+// BLOCK-MAPPING-START
+// KEY
+// SCALAR("key 1",plain)
+// VALUE
+// SCALAR("value 1",plain)
+// KEY
+// SCALAR("key 2",plain)
+// VALUE
+// SCALAR("value 2",plain)
+// BLOCK-END
+// BLOCK-END
+// STREAM-END
+//
+// 2. Block mappings:
+//
+// a simple key: a value # The KEY token is produced here.
+// ? a complex key
+// : another value
+// a mapping:
+// key 1: value 1
+// key 2: value 2
+// a sequence:
+// - item 1
+// - item 2
+//
+// Tokens:
+//
+// STREAM-START(utf-8)
+// BLOCK-MAPPING-START
+// KEY
+// SCALAR("a simple key",plain)
+// VALUE
+// SCALAR("a value",plain)
+// KEY
+// SCALAR("a complex key",plain)
+// VALUE
+// SCALAR("another value",plain)
+// KEY
+// SCALAR("a mapping",plain)
+// BLOCK-MAPPING-START
+// KEY
+// SCALAR("key 1",plain)
+// VALUE
+// SCALAR("value 1",plain)
+// KEY
+// SCALAR("key 2",plain)
+// VALUE
+// SCALAR("value 2",plain)
+// BLOCK-END
+// KEY
+// SCALAR("a sequence",plain)
+// VALUE
+// BLOCK-SEQUENCE-START
+// BLOCK-ENTRY
+// SCALAR("item 1",plain)
+// BLOCK-ENTRY
+// SCALAR("item 2",plain)
+// BLOCK-END
+// BLOCK-END
+// STREAM-END
+//
+// YAML does not always require to start a new block collection from a new
+// line. If the current line contains only '-', '?', and ':' indicators, a new
+// block collection may start at the current line. The following examples
+// illustrate this case:
+//
+// 1. Collections in a sequence:
+//
+// - - item 1
+// - item 2
+// - key 1: value 1
+// key 2: value 2
+// - ? complex key
+// : complex value
+//

+// KEY
+// SCALAR("complex key")
+// VALUE
+// SCALAR("complex value")
+// BLOCK-END
+// BLOCK-END
+// STREAM-END
+//
+// 2. Collections in a mapping:
+//
+// ? a sequence
+// : - item 1
+// - item 2
+// ? a mapping
+// : key 1: value 1
+// key 2: value 2
+//
+// Tokens:

+
+Package `gorilla/mux` implements a request router and dispatcher for matching incoming requests to
+their respective handler.
+
+The name mux stands for "HTTP request multiplexer". Like the standard `http.ServeMux`, `mux.Router` matches incoming requests against a list of registered routes and calls a handler for the route that matches the URL or other conditions. The main features are:
+
+* It implements the `http.Handler` interface so it is compatible with the standard `http.ServeMux`.
+* Requests can be matched based on URL host, path, path prefix, schemes, header and query values, HTTP methods or using custom matchers.
+* URL hosts, paths and query values can have variables with an optional regular expression.
+* Registered URLs can be built, or "reversed", which helps maintaining references to resources.
+* Routes can be used as subrouters: nested routes are only tested if the parent route matches. This is useful to define groups of routes that share common conditions like a host, a path prefix or other repeated attributes. As a bonus, this optimizes request matching.

+
+## Install
+
+With a [correctly configured](https://golang.org/doc/install#testing) Go toolchain:
+
+```sh
+go get -u github.com/gorilla/mux
+```
+
+## Examples
+
+Let's start registering a couple of URL paths and handlers:
+
+```go
+func main() {
+ r := mux.NewRouter()
+ r.HandleFunc("/", HomeHandler)
+ r.HandleFunc("/products", ProductsHandler)
+ r.HandleFunc("/articles", ArticlesHandler)
+ http.Handle("/", r)
+}
+```
+
+Here we register three routes mapping URL paths to handlers. This is equivalent to how `http.HandleFunc()` works: if an incoming request URL matches one of the paths, the corresponding handler is called passing (`http.ResponseWriter`, `*http.Request`) as parameters.
+
+Paths can have variables. They are defined using the format `{name}` or `{name:pattern}`. If a regular expression pattern is not defined, the matched variable will be anything until the next slash. For example:
+
+```go
+r := mux.NewRouter()
+r.HandleFunc("/products/{key}", ProductHandler)
+r.HandleFunc("/articles/{category}/", ArticlesCategoryHandler)
+r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler)
+```
+
+The names are used to create a map of route variables which can be retrieved calling `mux.Vars()`:
+
+```go
+func ArticlesCategoryHandler(w http.ResponseWriter, r *http.Request) {
+ vars := mux.Vars(r)
+ w.WriteHeader(http.StatusOK)
+ fmt.Fprintf(w, "Category: %v\n", vars["category"])
+}
+```
+
+And this is all you need to know about the basic usage. More advanced options are explained below.
+
+### Matching Routes
+
+Routes can also be restricted to a domain or subdomain. Just define a host pattern to be matched. They can also have variables:
+
+```go
+r := mux.NewRouter()
+// Only matches if domain is "www.example.com".
+r.Host("www.example.com")
+// Matches a dynamic subdomain.
+r.Host("{subdomain:[a-z]+}.example.com")
+```
+
+There are several other matchers that can be added. To match path prefixes:
+
+```go
+r.PathPrefix("/products/")
+```
+
+...or HTTP methods:
+
+```go
+r.Methods("GET", "POST")
+```
+
+...or URL schemes:
+
+```go
+r.Schemes("https")
+```
+
+...or header values:
+
+```go
+r.Headers("X-Requested-With", "XMLHttpRequest")
+```
+
+...or query values:
+
+```go
+r.Queries("key", "value")
+```
+
+...or to use a custom matcher function:
+
+```go
+r.MatcherFunc(func(r *http.Request, rm *RouteMatch) bool {
+ return r.ProtoMajor == 0
+})
+```
+
+...and finally, it is possible to combine several matchers in a single route:
+
+```go
+r.HandleFunc("/products", ProductsHandler).
+ Host("www.example.com").
+ Methods("GET").
+ Schemes("http")
+```
+
+Routes are tested in the order they were added to the router. If two routes match, the first one wins:
+
+```go
+r := mux.NewRouter()
+r.HandleFunc("/specific", specificHandler)
+r.PathPrefix("/").Handler(catchAllHandler)
+```
+
+Setting the same matching conditions again and again can be boring, so we have a way to group several routes that share the same requirements. We call it "subrouting".
+
+For example, let's say we have several URLs that should only match when the host is `www.example.com`. Create a route for that host and get a "subrouter" from it:
+
+```go
+r := mux.NewRouter()
+s := r.Host("www.example.com").Subrouter()
+```
+
+Then register routes in the subrouter:
+
+```go
+s.HandleFunc("/products/", ProductsHandler)
+s.HandleFunc("/products/{key}", ProductHandler)
+s.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler)
+```
+
+The three URL paths we registered above will only be tested if the domain is `www.example.com`, because the subrouter is tested first. This is not only convenient, but also optimizes request matching. You can create subrouters combining any attribute matchers accepted by a route.
+
+Subrouters can be used to create domain or path "namespaces": you define subrouters in a central place and then parts of the app can register its paths relatively to a given subrouter.
+
+There's one more thing about subroutes. When a subrouter has a path prefix, the inner routes use it as base for their paths:
+
+```go
+r := mux.NewRouter()
+s := r.PathPrefix("/products").Subrouter()
+// "/products/"
+s.HandleFunc("/", ProductsHandler)
+// "/products/{key}/"
+s.HandleFunc("/{key}/", ProductHandler)
+// "/products/{key}/details"
+s.HandleFunc("/{key}/details", ProductDetailsHandler)
+```
+
+
+### Static Files
+
+Note that the path provided to `PathPrefix()` represents a "wildcard": calling
+`PathPrefix("/static/").Handler(...)` means that the handler will be passed any
+request that matches "/static/\*". This makes it easy to serve static files with mux:
+
+```go
+func main() {
+ var dir string
+
+ flag.StringVar(&dir, "dir", ".", "the directory to serve files from. Defaults to the current dir")
+ flag.Parse()
+ r := mux.NewRouter()
+
+ // This will serve files under http://localhost:8000/static/
+ r.PathPrefix("/static/").Handler(http.StripPrefix("/static/", http.FileServer(http.Dir(dir))))
+
+ srv := &http.Server{
+ Handler: r,
+ Addr: "127.0.0.1:8000",
+ // Good practice: enforce timeouts for servers you create!
+ WriteTimeout: 15 * time.Second,
+ ReadTimeout: 15 * time.Second,
+ }
+
+ log.Fatal(srv.ListenAndServe())
+}
+```
+
+### Registered URLs
+
+Now let's see how to build registered URLs.
+
+Routes can be named. All routes that define a name can have their URLs built, or "reversed". We define a name calling `Name()` on a route. For example:
+
+```go
+r := mux.NewRouter()
+r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler).
+ Name("article")
+```
+
+To build a URL, get the route and call the `URL()` method, passing a sequence of key/value pairs for the route variables. For the previous route, we would do:
+
+```go
+url, err := r.Get("article").URL("category", "technology", "id", "42")
+```
+
+...and the result will be a `url.URL` with the following path:
+
+```
+"/articles/technology/42"
+```
+
+This also works for host and query value variables:
+
+```go
+r := mux.NewRouter()
+r.Host("{subdomain}.example.com").
+ Path("/articles/{category}/{id:[0-9]+}").
+ Queries("filter", "{filter}").
+ HandlerFunc(ArticleHandler).
+ Name("article")
+
+// url.String() will be "http://news.example.com/articles/technology/42?filter=gorilla"
+url, err := r.Get("article").URL("subdomain", "news",
+ "category", "technology",
+ "id", "42",
+ "filter", "gorilla")
+```
+
+All variables defined in the route are required, and their values must conform to the corresponding patterns. These requirements guarantee that a generated URL will always match a registered route -- the only exception is for explicitly defined "build-only" routes which never match.
+
+Regex support also exists for matching Headers within a route. For example, we could do:
+
+```go
+r.HeadersRegexp("Content-Type", "application/(text|json)")
+```
+
+...and the route will match both requests with a Content-Type of `application/json` as well as `application/text`
+
+There's also a way to build only the URL host or path for a route: use the methods `URLHost()` or `URLPath()` instead. For the previous route, we would do:
+
+```go
+// "http://news.example.com/"
+host, err := r.Get("article").URLHost("subdomain", "news")
+
+// "/articles/technology/42"
+path, err := r.Get("article").URLPath("category", "technology", "id", "42")
+```
+
+And if you use subrouters, host and path defined separately can be built as well:
+
+```go
+r := mux.NewRouter()
+s := r.Host("{subdomain}.example.com").Subrouter()
+s.Path("/articles/{category}/{id:[0-9]+}").
+ HandlerFunc(ArticleHandler).
+ Name("article")
+
+// "http://news.example.com/articles/technology/42"
+url, err := r.Get("article").URL("subdomain", "news",
+ "category", "technology",
+ "id", "42")
+```
+
+### Walking Routes
+
+The `Walk` function on `mux.Router` can be used to visit all of the routes that are registered on a router. For example,
+the following prints all of the registered routes:
+
+```go
+package main
+
+import (
+ "fmt"
+ "net/http"
+ "strings"
+
+ "github.com/gorilla/mux"
+)
+
+func handler(w http.ResponseWriter, r *http.Request) {
+ return
+}
+
+func main() {
+ r := mux.NewRouter()
+ r.HandleFunc("/", handler)
+ r.HandleFunc("/products", handler).Methods("POST")
+ r.HandleFunc("/articles", handler).Methods("GET")
+ r.HandleFunc("/articles/{id}", handler).Methods("GET", "PUT")
+ r.HandleFunc("/authors", handler).Queries("surname", "{surname}")
+ err := r.Walk(func(route *mux.Route, router *mux.Router, ancestors []*mux.Route) error {
+ pathTemplate, err := route.GetPathTemplate()
+ if err == nil {
+ fmt.Println("ROUTE:", pathTemplate)
+ }
+ pathRegexp, err := route.GetPathRegexp()
+ if err == nil {
+ fmt.Println("Path regexp:", pathRegexp)
+ }
+ queriesTemplates, err := route.GetQueriesTemplates()
+ if err == nil {
+ fmt.Println("Queries templates:", strings.Join(queriesTemplates, ","))
+ }
+ queriesRegexps, err := route.GetQueriesRegexp()
+ if err == nil {
+ fmt.Println("Queries regexps:", strings.Join(queriesRegexps, ","))
+ }
+ methods, err := route.GetMethods()
+ if err == nil {
+ fmt.Println("Methods:", strings.Join(methods, ","))
+ }
+ fmt.Println()
+ return nil
+ })
+
+ if err != nil {
+ fmt.Println(err)
+ }
+
+ http.Handle("/", r)
+}
+```
+
+### Graceful Shutdown
+
+Go 1.8 introduced the ability to [gracefully shutdown](https://golang.org/doc/go1.8#http_shutdown) a `*http.Server`. Here's how to do that alongside `mux`:
+
+```go
+package main
+
+import (
+ "context"
+ "flag"
+ "log"
+ "net/http"
+ "os"
+ "os/signal"
+ "time"
+
+ "github.com/gorilla/mux"
+)
+
+func main() {
+ var wait time.Duration
+ flag.DurationVar(&wait, "graceful-timeout", time.Second * 15, "the duration for which the server gracefully wait for existing connections to finish - e.g. 15s or 1m")
+ flag.Parse()
+
+ r := mux.NewRouter()
+ // Add your routes as needed
+
+ srv := &http.Server{
+ Addr: "0.0.0.0:8080",
+ // Good practice to set timeouts to avoid Slowloris attacks.
+ WriteTimeout: time.Second * 15,
+ ReadTimeout: time.Second * 15,
+ IdleTimeout: time.Second * 60,
+ Handler: r, // Pass our instance of gorilla/mux in.
+ }
+
+ // Run our server in a goroutine so that it doesn't block.
+ go func() {
+ if err := srv.ListenAndServe(); err != nil {
+ log.Println(err)
+ }
+ }()
+
+ c := make(chan os.Signal, 1)
+ // We'll accept graceful shutdowns when quit via SIGINT (Ctrl+C)
+ // SIGKILL, SIGQUIT or SIGTERM (Ctrl+/) will not be caught.
+ signal.Notify(c, os.Interrupt)
+
+ // Block until we receive our signal.
+ <-c
+
+ // Create a deadline to wait for.
+ ctx, cancel := context.WithTimeout(context.Background(), wait)
+ defer cancel()
+ // Doesn't block if no connections, but will otherwise wait
+ // until the timeout deadline.
+ srv.Shutdown(ctx)
+ // Optionally, you could run srv.Shutdown in a goroutine and block on
+ // <-ctx.Done() if your application should wait for other services
+ // to finalize based on context cancellation.
+ log.Println("shutting down")
+ os.Exit(0)
+}
+```
+
+### Middleware
+
+Mux supports the addition of middlewares to a [Router](https://godoc.org/github.com/gorilla/mux#Router), which are executed in the order they are added if a match is found, including its subrouters.
+Middlewares are (typically) small pieces of code which take one request, do something with it, and pass it down to another middleware or the final handler. Some common use cases for middleware are request logging, header manipulation, or `ResponseWriter` hijacking.
+
+Mux middlewares are defined using the de facto standard type:
+
+```go
+type MiddlewareFunc func(http.Handler) http.Handler
+```
+
+Typically, the returned handler is a closure which does something with the http.ResponseWriter and http.Request passed to it, and then calls the handler passed as parameter to the MiddlewareFunc. This takes advantage of closures being able access variables from the context where they are created, while retaining the signature enforced by the receivers.
+
+A very basic middleware which logs the URI of the request being handled could be written as:
+
+```go
+func loggingMiddleware(next http.Handler) http.Handler {
+ return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
+ // Do stuff here
+ log.Println(r.RequestURI)
+ // Call the next handler, which can be another middleware in the chain, or the final handler.
+ next.ServeHTTP(w, r)
+ })
+}
+```
+
+Middlewares can be added to a router using `Router.Use()`:
+
+```go
+r := mux.NewRouter()
+r.HandleFunc("/", handler)
+r.Use(loggingMiddleware)
+```
+
+A more complex authentication middleware, which maps session token to users, could be written as:
+
+```go
+// Define our struct
+type authenticationMiddleware struct {
+ tokenUsers map[string]string
+}
+
+// Initialize it somewhere
+func (amw *authenticationMiddleware) Populate() {
+ amw.tokenUsers["00000000"] = "user0"
+ amw.tokenUsers["aaaaaaaa"] = "userA"
+ amw.tokenUsers["05f717e5"] = "randomUser"
+ amw.tokenUsers["deadbeef"] = "user0"
+}
+
+// Middleware function, which will be called for each request
+func (amw *authenticationMiddleware) Middleware(next http.Handler) http.Handler {
+ return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
+ token := r.Header.Get("X-Session-Token")
+
+ if user, found := amw.tokenUsers[token]; found {
+ // We found the token in our map
+ log.Printf("Authenticated user %s\n", user)
+ // Pass down the request to the next middleware (or final handler)
+ next.ServeHTTP(w, r)
+ } else {
+ // Write an error and stop the handler chain
+ http.Error(w, "Forbidden", http.StatusForbidden)
+ }
+ })
+}
+```
+
+```go
+r := mux.NewRouter()
+r.HandleFunc("/", handler)
+
+amw := authenticationMiddleware{}
+amw.Populate()
+
+r.Use(amw.Middleware)
+```
+
+Note: The handler chain will be stopped if your middleware doesn't call `next.ServeHTTP()` with the corresponding parameters. This can be used to abort a request if the middleware writer wants to. Middlewares _should_ write to `ResponseWriter` if they _are_ going to terminate the request, and they _should not_ write to `ResponseWriter` if they _are not_ going to terminate it.
+
+### Testing Handlers
+
+Testing handlers in a Go web application is straightforward, and _mux_ doesn't complicate this any further. Given two files: `endpoints.go` and `endpoints_test.go`, here's how we'd test an application using _mux_.
+
+First, our simple HTTP handler:
+
+```go
+// endpoints.go
+package main
+
+func HealthCheckHandler(w http.ResponseWriter, r *http.Request) {
+ // A very simple health check.
+ w.Header().Set("Content-Type", "application/json")
+ w.WriteHeader(http.StatusOK)
+
+ // In the future we could report back on the status of our DB, or our cache
+ // (e.g. Redis) by performing a simple PING, and include them in the response.
+ io.WriteString(w, `{"alive": true}`)
+}
+
+func main() {
+ r := mux.NewRouter()
+ r.HandleFunc("/health", HealthCheckHandler)
+
+ log.Fatal(http.ListenAndServe("localhost:8080", r))
+}
+```
+
+Our test code:
+
+```go
+// endpoints_test.go
+package main
+
+import (
+ "net/http"
+ "net/http/httptest"
+ "testing"
+)
+
+func TestHealthCheckHandler(t *testing.T) {
+ // Create a request to pass to our handler. We don't have any query parameters for now, so we'll
+ // pass 'nil' as the third parameter.
+ req, err := http.NewRequest("GET", "/health", nil)
+ if err != nil {
+ t.Fatal(err)
+ }
+
+ // We create a ResponseRecorder (which satisfies http.ResponseWriter) to record the response.
+ rr := httptest.NewRecorder()
+ handler := http.HandlerFunc(HealthCheckHandler)
+
+ // Our handlers satisfy http.Handler, so we can call their ServeHTTP method
+ // directly and pass in our Request and ResponseRecorder.
+ handler.ServeHTTP(rr, req)
+
+ // Check the status code is what we expect.
+ if status := rr.Code; status != http.StatusOK {
+ t.Errorf("handler returned wrong status code: got %v want %v",
+ status, http.StatusOK)
+ }
+
+ // Check the response body is what we expect.
+ expected := `{"alive": true}`
+ if rr.Body.String() != expected {
+ t.Errorf("handler returned unexpected body: got %v want %v",
+ rr.Body.String(), expected)
+ }
+}
+```
+
+In the case that our routes have [variables](#examples), we can pass those in the request. We could write
+[table-driven tests](https://dave.cheney.net/2013/06/09/writing-table-driven-tests-in-go) to test multiple
+possible route variables as needed.
+
+```go
+// endpoints.go
+func main() {
+ r := mux.NewRouter()
+ // A route with a route variable:
+ r.HandleFunc("/metrics/{type}", MetricsHandler)
+
+ log.Fatal(http.ListenAndServe("localhost:8080", r))
+}
+```
+
+Our test file, with a table-driven test of `routeVariables`:
+
+```go
+// endpoints_test.go
+func TestMetricsHandler(t *testing.T) {
+ tt := []struct{
+ routeVariable string
+ shouldPass bool
+ }{
+ {"goroutines", true},
+ {"heap", true},
+ {"counters", true},
+ {"queries", true},
+ {"adhadaeqm3k", false},
+ }
+
+ for _, tc := range tt {
+ path := fmt.Sprintf("/metrics/%s", tc.routeVariable)
+ req, err := http.NewRequest("GET", path, nil)
+ if err != nil {
+ t.Fatal(err)
+ }
+
+ rr := httptest.NewRecorder()
+
+ // Need to create a router that we can pass the request through so that the vars will be added to the context
+ router := mux.NewRouter()
+ router.HandleFunc("/metrics/{type}", MetricsHandler)
+ router.ServeHTTP(rr, req)
+
+ // In this case, our MetricsHandler returns a non-200 response
+ // for a route variable it doesn't know about.
+ if rr.Code == http.StatusOK && !tc.shouldPass {
+ t.Errorf("handler should have failed on routeVariable %s: got %v want %v",
+ tc.routeVariable, rr.Code, http.StatusOK)
+ }
+ }
+}
+```
+
+## Full Example
+
+Here's a complete, runnable example of a small `mux` based server:
+
+```go
+package main
+
+import (
+ "net/http"
+ "log"
+ "github.com/gorilla/mux"
+)
+
+func YourHandler(w http.ResponseWriter, r *http.Request) {
+ w.Write([]byte("Gorilla!\n"))
+}
+
+func main() {
+ r := mux.NewRouter()
+ // Routes consist of a path and a handler function.
+ r.HandleFunc("/", YourHandler)
+
+ // Bind to a port and pass our router in
+ log.Fatal(http.ListenAndServe(":8000", r))
+}
+```

+Package mux implements a request router and dispatcher.
+
+The name mux stands for "HTTP request multiplexer". Like the standard
+http.ServeMux, mux.Router matches incoming requests against a list of
+registered routes and calls a handler for the route that matches the URL
+or other conditions. The main features are:
+
+ * Requests can be matched based on URL host, path, path prefix, schemes,
+ header and query values, HTTP methods or using custom matchers.
+ * URL hosts, paths and query values can have variables with an optional
+ regular expression.
+ * Registered URLs can be built, or "reversed", which helps maintaining
+ references to resources.
+ * Routes can be used as subrouters: nested routes are only tested if the
+ parent route matches. This is useful to define groups of routes that
+ share common conditions like a host, a path prefix or other repeated
+ attributes. As a bonus, this optimizes request matching.
+ * It implements the http.Handler interface so it is compatible with the
+ standard http.ServeMux.
+
+Let's start registering a couple of URL paths and handlers:
+
+ func main() {
+ r := mux.NewRouter()
+ r.HandleFunc("/", HomeHandler)
+ r.HandleFunc("/products", ProductsHandler)
+ r.HandleFunc("/articles", ArticlesHandler)
+ http.Handle("/", r)
+ }
+
+Here we register three routes mapping URL paths to handlers. This is
+equivalent to how http.HandleFunc() works: if an incoming request URL matches
+one of the paths, the corresponding handler is called passing
+(http.ResponseWriter, *http.Request) as parameters.
+
+Paths can have variables. They are defined using the format {name} or
+{name:pattern}. If a regular expression pattern is not defined, the matched
+variable will be anything until the next slash. For example:
+
+ r := mux.NewRouter()
+ r.HandleFunc("/products/{key}", ProductHandler)
+ r.HandleFunc("/articles/{category}/", ArticlesCategoryHandler)
+ r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler)
+
+Groups can be used inside patterns, as long as they are non-capturing (?:re). For example:
+
+ r.HandleFunc("/articles/{category}/{sort:(?:asc|desc|new)}", ArticlesCategoryHandler)
+
+The names are used to create a map of route variables which can be retrieved
+calling mux.Vars():
+
+ vars := mux.Vars(request)
+ category := vars["category"]
+
+Note that if any capturing groups are present, mux will panic() during parsing. To prevent
+this, convert any capturing groups to non-capturing, e.g. change "/{sort:(asc|desc)}" to
+"/{sort:(?:asc|desc)}". This is a change from prior versions which behaved unpredictably
+when capturing groups were present.
+
+And this is all you need to know about the basic usage. More advanced options
+are explained below.
+
+Routes can also be restricted to a domain or subdomain. Just define a host
+pattern to be matched. They can also have variables:
+
+ r := mux.NewRouter()
+ // Only matches if domain is "www.example.com".
+ r.Host("www.example.com")
+ // Matches a dynamic subdomain.
+ r.Host("{subdomain:[a-z]+}.domain.com")
+
+There are several other matchers that can be added. To match path prefixes:
+
+ r.PathPrefix("/products/")
+
+...or HTTP methods:
+
+ r.Methods("GET", "POST")
+
+...or URL schemes:
+
+ r.Schemes("https")
+
+...or header values:
+
+ r.Headers("X-Requested-With", "XMLHttpRequest")
+
+...or query values:
+
+ r.Queries("key", "value")
+
+...or to use a custom matcher function:
+
+ r.MatcherFunc(func(r *http.Request, rm *RouteMatch) bool {
+ return r.ProtoMajor == 0
+ })
+
+...and finally, it is possible to combine several matchers in a single route:
+
+ r.HandleFunc("/products", ProductsHandler).
+ Host("www.example.com").
+ Methods("GET").
+ Schemes("http")
+
+Setting the same matching conditions again and again can be boring, so we have
+a way to group several routes that share the same requirements.
+We call it "subrouting".
+
+For example, let's say we have several URLs that should only match when the
+host is "www.example.com". Create a route for that host and get a "subrouter"
+from it:
+
+ r := mux.NewRouter()
+ s := r.Host("www.example.com").Subrouter()
+
+Then register routes in the subrouter:
+
+ s.HandleFunc("/products/", ProductsHandler)
+ s.HandleFunc("/products/{key}", ProductHandler)
+ s.HandleFunc("/articles/{category}/{id:[0-9]+}"), ArticleHandler)
+
+The three URL paths we registered above will only be tested if the domain is
+"www.example.com", because the subrouter is tested first. This is not
+only convenient, but also optimizes request matching. You can create
+subrouters combining any attribute matchers accepted by a route.
+
+Subrouters can be used to create domain or path "namespaces": you define
+subrouters in a central place and then parts of the app can register its
+paths relatively to a given subrouter.
+
+There's one more thing about subroutes. When a subrouter has a path prefix,
+the inner routes use it as base for their paths:
+
+ r := mux.NewRouter()
+ s := r.PathPrefix("/products").Subrouter()
+ // "/products/"
+ s.HandleFunc("/", ProductsHandler)
+ // "/products/{key}/"
+ s.HandleFunc("/{key}/", ProductHandler)
+ // "/products/{key}/details"
+ s.HandleFunc("/{key}/details", ProductDetailsHandler)
+
+Note that the path provided to PathPrefix() represents a "wildcard": calling
+PathPrefix("/static/").Handler(...) means that the handler will be passed any
+request that matches "/static/*". This makes it easy to serve static files with mux:
+
+ func main() {
+ var dir string
+
+ flag.StringVar(&dir, "dir", ".", "the directory to serve files from. Defaults to the current dir")
+ flag.Parse()
+ r := mux.NewRouter()
+
+ // This will serve files under http://localhost:8000/static/
+ r.PathPrefix("/static/").Handler(http.StripPrefix("/static/", http.FileServer(http.Dir(dir))))
+
+ srv := &http.Server{
+ Handler: r,
+ Addr: "127.0.0.1:8000",
+ // Good practice: enforce timeouts for servers you create!
+ WriteTimeout: 15 * time.Second,
+ ReadTimeout: 15 * time.Second,
+ }
+
+ log.Fatal(srv.ListenAndServe())
+ }
+
+Now let's see how to build registered URLs.
+
+Routes can be named. All routes that define a name can have their URLs built,
+or "reversed". We define a name calling Name() on a route. For example:
+
+ r := mux.NewRouter()
+ r.HandleFunc("/articles/{category}/{id:[0-9]+}", ArticleHandler).
+ Name("article")
+
+To build a URL, get the route and call the URL() method, passing a sequence of
+key/value pairs for the route variables. For the previous route, we would do:
+
+ url, err := r.Get("article").URL("category", "technology", "id", "42")
+
+...and the result will be a url.URL with the following path:
+
+ "/articles/technology/42"
+
+This also works for host and query value variables:
+
+ r := mux.NewRouter()
+ r.Host("{subdomain}.domain.com").
+ Path("/articles/{category}/{id:[0-9]+}").
+ Queries("filter", "{filter}").
+ HandlerFunc(ArticleHandler).
+ Name("article")
+
+ // url.String() will be "http://news.domain.com/articles/technology/42?filter=gorilla"
+ url, err := r.Get("article").URL("subdomain", "news",
+ "category", "technology",
+ "id", "42",
+ "filter", "gorilla")
+
+All variables defined in the route are required, and their values must
+conform to the corresponding patterns. These requirements guarantee that a
+generated URL will always match a registered route -- the only exception is
+for explicitly defined "build-only" routes which never match.
+
+Regex support also exists for matching Headers within a route. For example, we could do:
+
+ r.HeadersRegexp("Content-Type", "application/(text|json)")
+
+...and the route will match both requests with a Content-Type of `application/json` as well as
+`application/text`
+
+There's also a way to build only the URL host or path for a route:
+use the methods URLHost() or URLPath() instead. For the previous route,
+we would do:
+
+ // "http://news.domain.com/"
+ host, err := r.Get("article").URLHost("subdomain", "news")
+
+ // "/articles/technology/42"
+ path, err := r.Get("article").URLPath("category", "technology", "id", "42")
+
+And if you use subrouters, host and path defined separately can be built
+as well:
+
+ r := mux.NewRouter()
+ s := r.Host("{subdomain}.domain.com").Subrouter()
+ s.Path("/articles/{category}/{id:[0-9]+}").
+ HandlerFunc(ArticleHandler).
+ Name("article")
+
+ // "http://news.domain.com/articles/technology/42"
+ url, err := r.Get("article").URL("subdomain", "news",
+ "category", "technology",
+ "id", "42")
+
+Mux supports the addition of middlewares to a Router, which are executed in the order they are added if a match is found, including its subrouters. Middlewares are (typically) small pieces of code which take one request, do something with it, and pass it down to another middleware or the final handler. Some common use cases for middleware are request logging, header manipulation, or ResponseWriter hijacking.
+
+ type MiddlewareFunc func(http.Handler) http.Handler
+
+Typically, the returned handler is a closure which does something with the http.ResponseWriter and http.Request passed to it, and then calls the handler passed as parameter to the MiddlewareFunc (closures can access variables from the context where they are created).
+
+A very basic middleware which logs the URI of the request being handled could be written as:
+
+ func simpleMw(next http.Handler) http.Handler {
+ return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
+ // Do stuff here
+ log.Println(r.RequestURI)
+ // Call the next handler, which can be another middleware in the chain, or the final handler.
+ next.ServeHTTP(w, r)
+ })
+ }
+
+Middlewares can be added to a router using `Router.Use()`:
+
+ r := mux.NewRouter()
+ r.HandleFunc("/", handler)
+ r.Use(simpleMw)
+
+A more complex authentication middleware, which maps session token to users, could be written as:
+
+ // Define our struct
+ type authenticationMiddleware struct {
+ tokenUsers map[string]string
+ }
+
+ // Initialize it somewhere
+ func (amw *authenticationMiddleware) Populate() {
+ amw.tokenUsers["00000000"] = "user0"
+ amw.tokenUsers["aaaaaaaa"] = "userA"
+ amw.tokenUsers["05f717e5"] = "randomUser"
+ amw.tokenUsers["deadbeef"] = "user0"
+ }
+
+ // Middleware function, which will be called for each request
+ func (amw *authenticationMiddleware) Middleware(next http.Handler) http.Handler {
+ return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
+ token := r.Header.Get("X-Session-Token")
+
+ if user, found := amw.tokenUsers[token]; found {
+ // We found the token in our map
+ log.Printf("Authenticated user %s\n", user)
+ next.ServeHTTP(w, r)
+ } else {
+ http.Error(w, "Forbidden", http.StatusForbidden)
+ }
+ })
+ }
+
+ r := mux.NewRouter()
+ r.HandleFunc("/", handler)
+
+ amw := authenticationMiddleware{}
+ amw.Populate()
+
+ r.Use(amw.Middleware)
+

+# Building `sys/unix`
+
+The sys/unix package provides access to the raw system call interface of the
+underlying operating system. See: https://godoc.org/golang.org/x/sys/unix
+
+Porting Go to a new architecture/OS combination or adding syscalls, types, or
+constants to an existing architecture/OS pair requires some manual effort;
+however, there are tools that automate much of the process.
+
+## Build Systems
+
+There are currently two ways we generate the necessary files. We are currently
+migrating the build system to use containers so the builds are reproducible.
+This is being done on an OS-by-OS basis. Please update this documentation as
+components of the build system change.
+
+### Old Build System (currently for `GOOS != "linux"`)
+
+The old build system generates the Go files based on the C header files
+present on your system. This means that files
+for a given GOOS/GOARCH pair must be generated on a system with that OS and
+architecture. This also means that the generated code can differ from system
+to system, based on differences in the header files.
+
+To avoid this, if you are using the old build system, only generate the Go
+files on an installation with unmodified header files. It is also important to
+keep track of which version of the OS the files were generated from (ex.
+Darwin 14 vs Darwin 15). This makes it easier to track the progress of changes
+and have each OS upgrade correspond to a single change.
+
+To build the files for your current OS and architecture, make sure GOOS and
+GOARCH are set correctly and run `mkall.sh`. This will generate the files for
+your specific system. Running `mkall.sh -n` shows the commands that will be run.
+
+Requirements: bash, go
+
+### New Build System (currently for `GOOS == "linux"`)
+
+The new build system uses a Docker container to generate the go files directly
+from source checkouts of the kernel and various system libraries. This means
+that on any platform that supports Docker, all the files using the new build
+system can be generated at once, and generated files will not change based on
+what the person running the scripts has installed on their computer.
+
+The OS specific files for the new build system are located in the `${GOOS}`
+directory, and the build is coordinated by the `${GOOS}/mkall.go` program. When
+the kernel or system library updates, modify the Dockerfile at
+`${GOOS}/Dockerfile` to checkout the new release of the source.
+
+To build all the files under the new build system, you must be on an amd64/Linux
+system and have your GOOS and GOARCH set accordingly. Running `mkall.sh` will
+then generate all of the files for all of the GOOS/GOARCH pairs in the new build
+system. Running `mkall.sh -n` shows the commands that will be run.
+
+Requirements: bash, go, docker
+
+## Component files
+
+This section describes the various files used in the code generation process.
+It also contains instructions on how to modify these files to add a new
+architecture/OS or to add additional syscalls, types, or constants. Note that
+if you are using the new build system, the scripts/programs cannot be called normally.
+They must be called from within the docker container.
+
+### asm files
+
+The hand-written assembly file at `asm_${GOOS}_${GOARCH}.s` implements system
+call dispatch. There are three entry points:
+```
+ func Syscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr)
+ func Syscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr)
+ func RawSyscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr)
+```
+The first and second are the standard ones; they differ only in how many
+arguments can be passed to the kernel. The third is for low-level use by the
+ForkExec wrapper. Unlike the first two, it does not call into the scheduler to
+let it know that a system call is running.
+
+When porting Go to an new architecture/OS, this file must be implemented for
+each GOOS/GOARCH pair.
+
+### mksysnum
+
+Mksysnum is a Go program located at `${GOOS}/mksysnum.go` (or `mksysnum_${GOOS}.go`
+for the old system). This program takes in a list of header files containing the
+syscall number declarations and parses them to produce the corresponding list of
+Go numeric constants. See `zsysnum_${GOOS}_${GOARCH}.go` for the generated
+constants.
+
+Adding new syscall numbers is mostly done by running the build on a sufficiently
+new installation of the target OS (or updating the source checkouts for the
+new build system). However, depending on the OS, you make need to update the
+parsing in mksysnum.
+
+### mksyscall.go
+
+The `syscall.go`, `syscall_${GOOS}.go`, `syscall_${GOOS}_${GOARCH}.go` are
+hand-written Go files which implement system calls (for unix, the specific OS,
+or the specific OS/Architecture pair respectively) that need special handling
+and list `//sys` comments giving prototypes for ones that can be generated.
+
+The mksyscall.go program takes the `//sys` and `//sysnb` comments and converts
+them into syscalls. This requires the name of the prototype in the comment to
+match a syscall number in the `zsysnum_${GOOS}_${GOARCH}.go` file. The function
+prototype can be exported (capitalized) or not.
+
+Adding a new syscall often just requires adding a new `//sys` function prototype
+with the desired arguments and a capitalized name so it is exported. However, if
+you want the interface to the syscall to be different, often one will make an
+unexported `//sys` prototype, an then write a custom wrapper in
+`syscall_${GOOS}.go`.
+
+### types files
+
+For each OS, there is a hand-written Go file at `${GOOS}/types.go` (or
+`types_${GOOS}.go` on the old system). This file includes standard C headers and
+creates Go type aliases to the corresponding C types. The file is then fed
+through godef to get the Go compatible definitions. Finally, the generated code
+is fed though mkpost.go to format the code correctly and remove any hidden or
+private identifiers. This cleaned-up code is written to
+`ztypes_${GOOS}_${GOARCH}.go`.
+
+The hardest part about preparing this file is figuring out which headers to
+include and which symbols need to be `#define`d to get the actual data
+structures that pass through to the kernel system calls. Some C libraries
+preset alternate versions for binary compatibility and translate them on the
+way in and out of system calls, but there is almost always a `#define` that can
+get the real ones.
+See `types_darwin.go` and `linux/types.go` for examples.
+
+To add a new type, add in the necessary include statement at the top of the
+file (if it is not already there) and add in a type alias line. Note that if
+your type is significantly different on different architectures, you may need
+some `#if/#elif` macros in your include statements.
+
+### mkerrors.sh
+
+This script is used to generate the system's various constants. This doesn't
+just include the error numbers and error strings, but also the signal numbers
+an a wide variety of miscellaneous constants. The constants come from the list
+of include files in the `includes_${uname}` variable. A regex then picks out
+the desired `#define` statements, and generates the corresponding Go constants.
+The error numbers and strings are generated from `#include `, and the
+signal numbers and strings are generated from `#include `. All of
+these constants are written to `zerrors_${GOOS}_${GOARCH}.go` via a C program,
+`_errors.c`, which prints out all the constants.
+
+To add a constant, add the header that includes it to the appropriate variable.
+Then, edit the regex (if necessary) to match the desired constant. Avoid making
+the regex too broad to avoid matching unintended constants.
+
+
+## Generated files
+
+### `zerror_${GOOS}_${GOARCH}.go`
+
+A file containing all of the system's generated error numbers, error strings,
+signal numbers, and constants. Generated by `mkerrors.sh` (see above).
+
+### `zsyscall_${GOOS}_${GOARCH}.go`
+
+A file containing all the generated syscalls for a specific GOOS and GOARCH.
+Generated by `mksyscall.go` (see above).
+
+### `zsysnum_${GOOS}_${GOARCH}.go`
+
+A list of numeric constants for all the syscall number of the specific GOOS
+and GOARCH. Generated by mksysnum (see above).
+
+### `ztypes_${GOOS}_${GOARCH}.go`
+
+A file containing Go types for passing into (or returning from) syscalls.
+Generated by godefs and the types file (see above).

+This program reads a file containing function prototypes
+(like syscall_aix.go) and generates system call bodies.
+The prototypes are marked by lines beginning with "//sys"
+and read like func declarations if //sys is replaced by func, but:
+ * The parameter lists must give a name for each argument.
+ This includes return parameters.
+ * The parameter lists must give a type for each argument:
+ the (x, y, z int) shorthand is not allowed.
+ * If the return parameter is an error number, it must be named err.
+ * If go func name needs to be different than its libc name,
+ * or the function is not in libc, name could be specified
+ * at the end, after "=" sign, like
+ //sys getsockopt(s int, level int, name int, val uintptr, vallen *_Socklen) (err error) = libsocket.getsockopt
+
+
+This program will generate three files and handle both gc and gccgo implementation:
+ - zsyscall_aix_ppc64.go: the common part of each implementation (error handler, pointer creation)
+ - zsyscall_aix_ppc64_gc.go: gc part with //go_cgo_import_dynamic and a call to syscall6
+ - zsyscall_aix_ppc64_gccgo.go: gccgo part with C function and conversion to C type.
+
+ The generated code looks like this
+
+zsyscall_aix_ppc64.go
+func asyscall(...) (n int, err error) {
+ // Pointer Creation
+ r1, e1 := callasyscall(...)
+ // Type Conversion
+ // Error Handler

+// data can be written to the socket, processed by the kernel, and then read
+// back as hash output or ciphertext.
+//
+// Here is an example of using an AF_ALG socket with SHA1 hashing.
+// The initial socket setup process is as follows:
+//
+// // Open a socket to perform SHA1 hashing.
+// fd, _ := unix.Socket(unix.AF_ALG, unix.SOCK_SEQPACKET, 0)
+// addr := &unix.SockaddrALG{Type: "hash", Name: "sha1"}

+// // manually using unix.Syscall.
+// hashfd, _, _ := unix.Syscall(unix.SYS_ACCEPT, uintptr(fd), 0, 0)
+//
+// Once a file descriptor has been returned from Accept, it may be used to
+// perform SHA1 hashing. The descriptor is not safe for concurrent use, but
+// may be re-used repeatedly with subsequent Write and Read operations.
+//
+// When hashing a small byte slice or string, a single Write and Read may
+// be used:
+//
+// // Assume hashfd is already configured using the setup process.
+// hash := os.NewFile(hashfd, "sha1")
+// // Hash an input string and read the results. Each Write discards
+// // previous hash state. Read always reads the current state.
+// b := make([]byte, 20)
+// for i := 0; i < 2; i++ {
+// io.WriteString(hash, "Hello, world.")
+// hash.Read(b)
+// fmt.Println(hex.EncodeToString(b))
+// }

+// // 2ae01472317d1935a84797ec1983ae243fc6aa28
+//
+// For hashing larger byte slices, or byte streams such as those read from
+// a file or socket, use Sendto with MSG_MORE to instruct the kernel to update
+// the hash digest instead of creating a new one for a given chunk and finalizing it.
+//
+// // Assume hashfd and addr are already configured using the setup process.
