+// longest *contiguous* & junk-free matching subsequence. That's what
+// catches peoples' eyes. The Windows(tm) windiff has another interesting
+// notion, pairing up elements that appear uniquely in each sequence.
+// That, and the method here, appear to yield more intuitive difference
+// reports than does diff. This method appears to be the least vulnerable
+// to synching up on blocks of "junk lines", though (like blank lines in
+// ordinary text files, or maybe "" lines in HTML files). That may be
+// because this is the only method of the 3 that has a *concept* of
+// "junk" .
+//
+// Timing: Basic R-O is cubic time worst case and quadratic time expected
+// case. SequenceMatcher is quadratic time for the worst case and has
+// expected-case behavior dependent in a complicated way on how many
+// elements the sequences have in common; best case time is linear.

+
+Objx - Go package for dealing with maps, slices, JSON and other data.
+
+Get started:
+
+- Install Objx with [one line of code](#installation), or [update it with another](#staying-up-to-date)
+- Check out the API Documentation http://godoc.org/github.com/stretchr/objx
+
+## Overview
+Objx provides the `objx.Map` type, which is a `map[string]interface{}` that exposes a powerful `Get` method (among others) that allows you to easily and quickly get access to data within the map, without having to worry too much about type assertions, missing data, default values etc.
+
+### Pattern
+Objx uses a preditable pattern to make access data from within `map[string]interface{}` easy. Call one of the `objx.` functions to create your `objx.Map` to get going:
+
+ m, err := objx.FromJSON(json)
+
+NOTE: Any methods or functions with the `Must` prefix will panic if something goes wrong, the rest will be optimistic and try to figure things out without panicking.
+
+Use `Get` to access the value you're interested in. You can use dot and array
+notation too:
+
+ m.Get("places[0].latlng")
+
+Once you have sought the `Value` you're interested in, you can use the `Is*` methods to determine its type.
+
+ if m.Get("code").IsStr() { // Your code... }
+
+Or you can just assume the type, and use one of the strong type methods to extract the real value:
+
+ m.Get("code").Int()
+
+If there's no value there (or if it's the wrong type) then a default value will be returned, or you can be explicit about the default value.
+
+ Get("code").Int(-1)
+
+If you're dealing with a slice of data as a value, Objx provides many useful methods for iterating, manipulating and selecting that data. You can find out more by exploring the index below.
+
+### Reading data
+A simple example of how to use Objx:
+
+ // Use MustFromJSON to make an objx.Map from some JSON
+ m := objx.MustFromJSON(`{"name": "Mat", "age": 30}`)
+
+ // Get the details
+ name := m.Get("name").Str()
+ age := m.Get("age").Int()
+
+ // Get their nickname (or use their name if they don't have one)
+ nickname := m.Get("nickname").Str(name)
+
+### Ranging
+Since `objx.Map` is a `map[string]interface{}` you can treat it as such. For example, to `range` the data, do what you would expect:
+
+ m := objx.MustFromJSON(json)
+ for key, value := range m {
+ // Your code...
+ }
+
+## Installation
+To install Objx, use go get:
+
+ go get github.com/stretchr/objx
+
+### Staying up to date
+To update Objx to the latest version, run:
+
+ go get -u github.com/stretchr/objx
+
+### Supported go versions
+We support the lastest three major Go versions, which are 1.10, 1.11 and 1.12 at the moment.

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

+// Package mock provides a system by which it is possible to mock your objects
+// and verify calls are happening as expected.
+//
+// # Example Usage
+//
+// The mock package provides an object, Mock, that tracks activity on another object. It is usually
+// embedded into a test object as shown below:
+//
+// type MyTestObject struct {
+// // add a Mock object instance
+// mock.Mock
+//
+// // other fields go here as normal
+// }
+//
+// When implementing the methods of an interface, you wire your functions up
+// to call the Mock.Called(args...) method, and return the appropriate values.
+//
+// For example, to mock a method that saves the name and age of a person and returns
+// the year of their birth or an error, you might write this:
+//
+// func (o *MyTestObject) SavePersonDetails(firstname, lastname string, age int) (int, error) {
+// args := o.Called(firstname, lastname, age)
+// return args.Int(0), args.Error(1)
+// }
+//
+// The Int, Error and Bool methods are examples of strongly typed getters that take the argument
+// index position. Given this argument list:
+//
+// (12, true, "Something")
+//
+// You could read them out strongly typed like this:
+//
+// args.Int(0)
+// args.Bool(1)
+// args.String(2)
+//
+// For objects of your own type, use the generic Arguments.Get(index) method and make a type assertion:
+//
+// return args.Get(0).(*MyObject), args.Get(1).(*AnotherObjectOfMine)
+//
+// This may cause a panic if the object you are getting is nil (the type assertion will fail), in those
+// cases you should check for nil first.

+# multierr [![GoDoc][doc-img]][doc] [![Build Status][ci-img]][ci] [![Coverage Status][cov-img]][cov]
+
+`multierr` allows combining one or more Go `error`s together.
+
+## Features
+
+- **Idiomatic**:
+ multierr follows best practices in Go, and keeps your code idiomatic.
+ - It keeps the underlying error type hidden,
+ allowing you to deal in `error` values exclusively.
+ - It provides APIs to safely append into an error from a `defer` statement.
+- **Performant**:
+ multierr is optimized for performance:
+ - It avoids allocations where possible.
+ - It utilizes slice resizing semantics to optimize common cases
+ like appending into the same error object from a loop.
+- **Interoperable**:
+ multierr interoperates with the Go standard library's error APIs seamlessly:
+ - The `errors.Is` and `errors.As` functions *just work*.
+- **Lightweight**:
+ multierr comes with virtually no dependencies.
+
+## Installation
+
+```bash
+go get -u go.uber.org/multierr@latest
+```
+
+## Status
+
+Stable: No breaking changes will be made before 2.0.

+// Package multierr allows combining one or more errors together.
+//
+// # Overview
+//
+// Errors can be combined with the use of the Combine function.
+//
+// multierr.Combine(
+// reader.Close(),
+// writer.Close(),
+// conn.Close(),
+// )
+//
+// If only two errors are being combined, the Append function may be used
+// instead.
+//
+// err = multierr.Append(reader.Close(), writer.Close())
+//
+// The underlying list of errors for a returned error object may be retrieved
+// with the Errors function.
+//
+// errors := multierr.Errors(err)
+// if len(errors) > 0 {
+// fmt.Println("The following errors occurred:", errors)
+// }
+//
+// # Appending from a loop
+//
+// You sometimes need to append into an error from a loop.
+//
+// var err error
+// for _, item := range items {
+// err = multierr.Append(err, process(item))
+// }
+//
+// Cases like this may require knowledge of whether an individual instance
+// failed. This usually requires introduction of a new variable.
+//
+// var err error
+// for _, item := range items {
+// if perr := process(item); perr != nil {
+// log.Warn("skipping item", item)
+// err = multierr.Append(err, perr)
+// }
+// }
+//
+// multierr includes AppendInto to simplify cases like this.
+//
+// var err error
+// for _, item := range items {
+// if multierr.AppendInto(&err, process(item)) {
+// log.Warn("skipping item", item)
+// }
+// }
+//
+// This will append the error into the err variable, and return true if that
+// individual error was non-nil.
+//
+// See [AppendInto] for more information.
+//
+// # Deferred Functions
+//
+// Go makes it possible to modify the return value of a function in a defer
+// block if the function was using named returns. This makes it possible to
+// record resource cleanup failures from deferred blocks.
+//
+// func sendRequest(req Request) (err error) {
+// conn, err := openConnection()
+// if err != nil {
+// return err
+// }
+// defer func() {
+// err = multierr.Append(err, conn.Close())
+// }()
+// // ...
+// }
+//
+// multierr provides the Invoker type and AppendInvoke function to make cases
+// like the above simpler and obviate the need for a closure. The following is
+// roughly equivalent to the example above.
+//
+// func sendRequest(req Request) (err error) {
+// conn, err := openConnection()
+// if err != nil {
+// return err
+// }
+// defer multierr.AppendInvoke(&err, multierr.Close(conn))
+// // ...
+// }
+//
+// See [AppendInvoke] and [Invoker] for more information.
+//
+// NOTE: If you're modifying an error from inside a defer, you MUST use a named
+// return value for that function.
+//
+// # Advanced Usage
+//
+// Errors returned by Combine and Append MAY implement the following
+// interface.
+//
+// type errorGroup interface {
+// // Returns a slice containing the underlying list of errors.
+// //
+// // This slice MUST NOT be modified by the caller.
+// Errors() []error
+// }
+//
+// Note that if you need access to list of errors behind a multierr error, you
+// should prefer using the Errors function. That said, if you need cheap
+// read-only access to the underlying errors slice, you can attempt to cast
+// the error to this interface. You MUST handle the failure case gracefully
+// because errors returned by Combine and Append are not guaranteed to
+// implement this interface.
+//
+// var errors []error
+// group, ok := err.(errorGroup)
+// if ok {
+// errors = group.Errors()
+// } else {
+// errors = []error{err}

+# :zap: zap [![GoDoc][doc-img]][doc] [![Build Status][ci-img]][ci] [![Coverage Status][cov-img]][cov]
+
+Blazing fast, structured, leveled logging in Go.
+
+## Installation
+
+`go get -u go.uber.org/zap`
+
+Note that zap only supports the two most recent minor versions of Go.
+
+## Quick Start
+
+In contexts where performance is nice, but not critical, use the
+`SugaredLogger`. It's 4-10x faster than other structured logging
+packages and includes both structured and `printf`-style APIs.
+
+```go
+logger, _ := zap.NewProduction()
+defer logger.Sync() // flushes buffer, if any
+sugar := logger.Sugar()
+sugar.Infow("failed to fetch URL",
+ // Structured context as loosely typed key-value pairs.
+ "url", url,
+ "attempt", 3,
+ "backoff", time.Second,
+)
+sugar.Infof("Failed to fetch URL: %s", url)
+```
+
+When performance and type safety are critical, use the `Logger`. It's even
+faster than the `SugaredLogger` and allocates far less, but it only supports
+structured logging.
+
+```go
+logger, _ := zap.NewProduction()
+defer logger.Sync()
+logger.Info("failed to fetch URL",
+ // Structured context as strongly typed Field values.
+ zap.String("url", url),
+ zap.Int("attempt", 3),
+ zap.Duration("backoff", time.Second),
+)
+```
+
+See the [documentation][doc] and [FAQ](FAQ.md) for more details.
+
+## Performance
+
+For applications that log in the hot path, reflection-based serialization and
+string formatting are prohibitively expensive — they're CPU-intensive
+and make many small allocations. Put differently, using `encoding/json` and
+`fmt.Fprintf` to log tons of `interface{}`s makes your application slow.
+
+Zap takes a different approach. It includes a reflection-free, zero-allocation
+JSON encoder, and the base `Logger` strives to avoid serialization overhead
+and allocations wherever possible. By building the high-level `SugaredLogger`
+on that foundation, zap lets users *choose* when they need to count every
+allocation and when they'd prefer a more familiar, loosely typed API.
+
+As measured by its own [benchmarking suite][], not only is zap more performant
+than comparable structured logging packages — it's also faster than the
+standard library. Like all benchmarks, take these with a grain of salt.[1](#footnote-versions)
+
+Log a message and 10 fields:
+
+{{.BenchmarkAddingFields}}
+
+Log a message with a logger that already has 10 fields of context:
+
+{{.BenchmarkAccumulatedContext}}
+
+Log a static string, without any context or `printf`-style templating:
+
+{{.BenchmarkWithoutFields}}
+
+## Development Status: Stable
+
+All APIs are finalized, and no breaking changes will be made in the 1.x series
+of releases. Users of semver-aware dependency management systems should pin
+zap to `^1`.
+
+## Contributing
+
+We encourage and support an active, healthy community of contributors —
+including you! Details are in the [contribution guide](CONTRIBUTING.md) and
+the [code of conduct](CODE_OF_CONDUCT.md). The zap maintainers keep an eye on
+issues and pull requests, but you can also report any negative conduct to
+oss-conduct@uber.com. That email list is a private, safe space; even the zap
+maintainers don't have access, so don't hesitate to hold us to a high
+standard.

+# Changelog
+All notable changes to this project will be documented in this file.
+
+This project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## 1.26.0 (14 Sep 2023)
+Enhancements:
+* [#1319][]: Add `WithLazy` method to `Logger` which lazily evaluates the structured
+context.
+* [#1350][]: String encoding is much (~50%) faster now.
+
+Thanks to @jquirke, @cdvr1993 for their contributions to this release.
+
+[#1319]: https://github.com/uber-go/zap/pull/1319
+[#1350]: https://github.com/uber-go/zap/pull/1350
+
+## 1.25.0 (1 Aug 2023)
+
+This release contains several improvements including performance, API additions,
+and two new experimental packages whose APIs are unstable and may change in the
+future.
+
+Enhancements:
+* [#1246][]: Add `zap/exp/zapslog` package for integration with slog.
+* [#1273][]: Add `Name` to `Logger` which returns the Logger's name if one is set.
+* [#1281][]: Add `zap/exp/expfield` package which contains helper methods
+`Str` and `Strs` for constructing String-like zap.Fields.
+* [#1310][]: Reduce stack size on `Any`.
+
+Thanks to @knight42, @dzakaammar, @bcspragu, and @rexywork for their contributions
+to this release.

+[#1310]: https://github.com/uber-go/zap/pull/1310
+
+## 1.24.0 (30 Nov 2022)
+
+Enhancements:
+* [#1148][]: Add `Level` to both `Logger` and `SugaredLogger` that reports the
+ current minimum enabled log level.
+* [#1185][]: `SugaredLogger` turns errors to zap.Error automatically.
+
+Thanks to @Abirdcfly, @craigpastro, @nnnkkk7, and @sashamelentyev for their
+contributions to this release.
+
+[#1148]: https://github.coml/uber-go/zap/pull/1148
+[#1185]: https://github.coml/uber-go/zap/pull/1185
+
+## 1.23.0 (24 Aug 2022)
+
+Enhancements:
+* [#1147][]: Add a `zapcore.LevelOf` function to determine the level of a
+ `LevelEnabler` or `Core`.
+* [#1155][]: Add `zap.Stringers` field constructor to log arrays of objects
+ that implement `String() string`.
+
+[#1147]: https://github.com/uber-go/zap/pull/1147
+[#1155]: https://github.com/uber-go/zap/pull/1155
+
+## 1.22.0 (8 Aug 2022)
+
+Enhancements:
+* [#1071][]: Add `zap.Objects` and `zap.ObjectValues` field constructors to log
+ arrays of objects. With these two constructors, you don't need to implement
+ `zapcore.ArrayMarshaler` for use with `zap.Array` if those objects implement
+ `zapcore.ObjectMarshaler`.
+* [#1079][]: Add `SugaredLogger.WithOptions` to build a copy of an existing
+ `SugaredLogger` with the provided options applied.
+* [#1080][]: Add `*ln` variants to `SugaredLogger` for each log level.
+ These functions provide a string joining behavior similar to `fmt.Println`.
+* [#1088][]: Add `zap.WithFatalHook` option to control the behavior of the
+ logger for `Fatal`-level log entries. This defaults to exiting the program.
+* [#1108][]: Add a `zap.Must` function that you can use with `NewProduction` or
+ `NewDevelopment` to panic if the system was unable to build the logger.
+* [#1118][]: Add a `Logger.Log` method that allows specifying the log level for
+ a statement dynamically.
+
+Thanks to @cardil, @craigpastro, @sashamelentyev, @shota3506, and @zhupeijun
+for their contributions to this release.

+* [#1048][]: Add `zap.ParseAtomicLevel` to parse an `AtomicLevel` from a
+ string.
+
+Bugfixes:
+* [#1058][]: Fix panic in JSON encoder when `EncodeLevel` is unset.
+
+Other changes:
+* [#1052][]: Improve encoding performance when the `AddCaller` and
+ `AddStacktrace` options are used together.

+## 1.16.0 (1 Sep 2020)
+
+Bugfixes:
+* [#828][]: Fix missing newline in IncreaseLevel error messages.
+* [#835][]: Fix panic in JSON encoder when encoding times or durations
+ without specifying a time or duration encoder.
+* [#843][]: Honor CallerSkip when taking stack traces.
+* [#862][]: Fix the default file permissions to use `0666` and rely on the umask instead.
+* [#854][]: Encode `` for nil `Stringer` instead of a panic error log.
+
+Enhancements:

+ for custom layouts.
+* [#697][]: Added support for a configurable delimiter in the console encoder.
+* [#852][]: Optimize console encoder by pooling the underlying JSON encoder.
+* [#844][]: Add ability to include the calling function as part of logs.
+* [#843][]: Add `StackSkip` for including truncated stacks as a field.
+* [#861][]: Add options to customize Fatal behaviour for better testability.
+
+Thanks to @SteelPhase, @tmshn, @lixingwang, @wyxloading, @moul, @segevfiner, @andy-retailnext and @jcorbin for their contributions to this release.

+[#386]: https://github.com/uber-go/zap/pull/386
+
+## v1.0.0 (14 Mar 2017)
+
+This is zap's first stable release. All exported APIs are now final, and no
+further breaking changes will be made in the 1.x release series. Anyone using a
+semver-aware dependency manager should now pin to `^1`.
+
+Breaking changes:
+
+* [#366][]: Add byte-oriented APIs to encoders to log UTF-8 encoded text without
+ casting from `[]byte` to `string`.
+* [#364][]: To support buffering outputs, add `Sync` methods to `zapcore.Core`,
+ `zap.Logger`, and `zap.SugaredLogger`.
+* [#371][]: Rename the `testutils` package to `zaptest`, which is less likely to
+ clash with other testing helpers.
+
+Bugfixes:
+
+* [#362][]: Make the ISO8601 time formatters fixed-width, which is friendlier
+ for tab-separated console output.
+* [#369][]: Remove the automatic locks in `zapcore.NewCore`, which allows zap to
+ work with concurrency-safe `WriteSyncer` implementations.
+* [#347][]: Stop reporting errors when trying to `fsync` standard out on Linux
+ systems.
+* [#373][]: Report the correct caller from zap's standard library
+ interoperability wrappers.
+
+Enhancements:
+
+* [#348][]: Add a registry allowing third-party encodings to work with zap's
+ built-in `Config`.
+* [#327][]: Make the representation of logger callers configurable (like times,
+ levels, and durations).
+* [#376][]: Allow third-party encoders to use their own buffer pools, which
+ removes the last performance advantage that zap's encoders have over plugins.
+* [#346][]: Add `CombineWriteSyncers`, a convenience function to tee multiple
+ `WriteSyncer`s and lock the result.
+* [#365][]: Make zap's stacktraces compatible with mid-stack inlining (coming in
+ Go 1.9).
+* [#372][]: Export zap's observing logger as `zaptest/observer`. This makes it
+ easier for particularly punctilious users to unit test their application's
+ logging.
+
+Thanks to @suyash, @htrendev, @flisky, @Ulexus, and @skipor for their
+contributions to this release.

+
+## v1.0.0-rc.3 (7 Mar 2017)
+
+This is the third release candidate for zap's stable release. There are no
+breaking changes.
+
+Bugfixes:
+
+* [#339][]: Byte slices passed to `zap.Any` are now correctly treated as binary blobs
+ rather than `[]uint8`.
+
+Enhancements:
+
+* [#307][]: Users can opt into colored output for log levels.
+* [#353][]: In addition to hijacking the output of the standard library's
+ package-global logging functions, users can now construct a zap-backed
+ `log.Logger` instance.
+* [#311][]: Frames from common runtime functions and some of zap's internal
+ machinery are now omitted from stacktraces.
+
+Thanks to @ansel1 and @suyash for their contributions to this release.

+[#311]: https://github.com/uber-go/zap/pull/311
+
+## v1.0.0-rc.2 (21 Feb 2017)
+
+This is the second release candidate for zap's stable release. It includes two
+breaking changes.
+
+Breaking changes:
+
+* [#316][]: Zap's global loggers are now fully concurrency-safe
+ (previously, users had to ensure that `ReplaceGlobals` was called before the
+ loggers were in use). However, they must now be accessed via the `L()` and
+ `S()` functions. Users can update their projects with
+
+ ```
+ gofmt -r "zap.L -> zap.L()" -w .
+ gofmt -r "zap.S -> zap.S()" -w .
+ ```
+* [#309][] and [#317][]: RC1 was mistakenly shipped with invalid
+ JSON and YAML struct tags on all config structs. This release fixes the tags
+ and adds static analysis to prevent similar bugs in the future.
+
+Bugfixes:
+
+* [#321][]: Redirecting the standard library's `log` output now
+ correctly reports the logger's caller.
+
+Enhancements:
+
+* [#325][] and [#333][]: Zap now transparently supports non-standard, rich
+ errors like those produced by `github.com/pkg/errors`.
+* [#326][]: Though `New(nil)` continues to return a no-op logger, `NewNop()` is
+ now preferred. Users can update their projects with `gofmt -r 'zap.New(nil) ->
+ zap.NewNop()' -w .`.
+* [#300][]: Incorrectly importing zap as `github.com/uber-go/zap` now returns a
+ more informative error.
+
+Thanks to @skipor and @chapsuk for their contributions to this release.

+[#300]: https://github.com/uber-go/zap/pull/300
+
+## v1.0.0-rc.1 (14 Feb 2017)
+
+This is the first release candidate for zap's stable release. There are multiple
+breaking changes and improvements from the pre-release version. Most notably:
+
+* **Zap's import path is now "go.uber.org/zap"** — all users will
+ need to update their code.
+* User-facing types and functions remain in the `zap` package. Code relevant
+ largely to extension authors is now in the `zapcore` package.
+* The `zapcore.Core` type makes it easy for third-party packages to use zap's
+ internals but provide a different user-facing API.
+* `Logger` is now a concrete type instead of an interface.
+* A less verbose (though slower) logging API is included by default.
+* Package-global loggers `L` and `S` are included.
+* A human-friendly console encoder is included.
+* A declarative config struct allows common logger configurations to be managed
+ as configuration instead of code.
+* Sampling is more accurate, and doesn't depend on the standard library's shared
+ timer heap.
+
+## v0.1.0-beta.1 (6 Feb 2017)
+
+This is a minor version, tagged to allow users to pin to the pre-1.0 APIs and
+upgrade at their leisure. Since this is the first tagged release, there are no
+backward compatibility concerns and all functionality is new.
+
+Early zap adopters should pin to the 0.1.x minor version until they're ready to
+upgrade to the upcoming stable release.

+# Frequently Asked Questions
+
+## Design
+
+### Why spend so much effort on logger performance?
+
+Of course, most applications won't notice the impact of a slow logger: they
+already take tens or hundreds of milliseconds for each operation, so an extra
+millisecond doesn't matter.
+
+On the other hand, why *not* make structured logging fast? The `SugaredLogger`
+isn't any harder to use than other logging packages, and the `Logger` makes
+structured logging possible in performance-sensitive contexts. Across a fleet
+of Go microservices, making each application even slightly more efficient adds
+up quickly.
+
+### Why aren't `Logger` and `SugaredLogger` interfaces?
+
+Unlike the familiar `io.Writer` and `http.Handler`, `Logger` and
+`SugaredLogger` interfaces would include *many* methods. As [Rob Pike points
+out][go-proverbs], "The bigger the interface, the weaker the abstraction."
+Interfaces are also rigid — *any* change requires releasing a new major
+version, since it breaks all third-party implementations.
+
+Making the `Logger` and `SugaredLogger` concrete types doesn't sacrifice much
+abstraction, and it lets us add methods without introducing breaking changes.
+Your applications should define and depend upon an interface that includes
+just the methods you use.
+
+### Why are some of my logs missing?
+
+Logs are dropped intentionally by zap when sampling is enabled. The production
+configuration (as returned by `NewProductionConfig()` enables sampling which will
+cause repeated logs within a second to be sampled. See more details on why sampling
+is enabled in [Why sample application logs](https://github.com/uber-go/zap/blob/master/FAQ.md#why-sample-application-logs).
+
+### Why sample application logs?
+
+Applications often experience runs of errors, either because of a bug or
+because of a misbehaving user. Logging errors is usually a good idea, but it
+can easily make this bad situation worse: not only is your application coping
+with a flood of errors, it's also spending extra CPU cycles and I/O logging
+those errors. Since writes are typically serialized, logging limits throughput
+when you need it most.
+
+Sampling fixes this problem by dropping repetitive log entries. Under normal
+conditions, your application writes out every entry. When similar entries are
+logged hundreds or thousands of times each second, though, zap begins dropping
+duplicates to preserve throughput.
+
+### Why do the structured logging APIs take a message in addition to fields?
+
+Subjectively, we find it helpful to accompany structured context with a brief
+description. This isn't critical during development, but it makes debugging
+and operating unfamiliar systems much easier.
+
+More concretely, zap's sampling algorithm uses the message to identify
+duplicate entries. In our experience, this is a practical middle ground
+between random sampling (which often drops the exact entry that you need while
+debugging) and hashing the complete entry (which is prohibitively expensive).
+
+### Why include package-global loggers?
+
+Since so many other logging packages include a global logger, many
+applications aren't designed to accept loggers as explicit parameters.
+Changing function signatures is often a breaking change, so zap includes
+global loggers to simplify migration.
+
+Avoid them where possible.
+
+### Why include dedicated Panic and Fatal log levels?
+
+In general, application code should handle errors gracefully instead of using
+`panic` or `os.Exit`. However, every rule has exceptions, and it's common to
+crash when an error is truly unrecoverable. To avoid losing any information
+— especially the reason for the crash — the logger must flush any
+buffered entries before the process exits.
+
+Zap makes this easy by offering `Panic` and `Fatal` logging methods that
+automatically flush before exiting. Of course, this doesn't guarantee that
+logs will never be lost, but it eliminates a common error.
+
+See the discussion in uber-go/zap#207 for more details.
+
+### What's `DPanic`?
+
+`DPanic` stands for "panic in development." In development, it logs at
+`PanicLevel`; otherwise, it logs at `ErrorLevel`. `DPanic` makes it easier to
+catch errors that are theoretically possible, but shouldn't actually happen,
+*without* crashing in production.
+
+If you've ever written code like this, you need `DPanic`:
+
+```go
+if err != nil {
+ panic(fmt.Sprintf("shouldn't ever get here: %v", err))
+}
+```
+
+## Installation
+
+### What does the error `expects import "go.uber.org/zap"` mean?
+
+Either zap was installed incorrectly or you're referencing the wrong package
+name in your code.
+
+Zap's source code happens to be hosted on GitHub, but the [import
+path][import-path] is `go.uber.org/zap`. This gives us, the project
+maintainers, the freedom to move the source code if necessary. However, it
+means that you need to take a little care when installing and using the
+package.
+
+If you follow two simple rules, everything should work: install zap with `go
+get -u go.uber.org/zap`, and always import it in your code with `import
+"go.uber.org/zap"`. Your code shouldn't contain *any* references to
+`github.com/uber-go/zap`.
+
+## Usage
+
+### Does zap support log rotation?
+
+Zap doesn't natively support rotating log files, since we prefer to leave this
+to an external program like `logrotate`.
+
+However, it's easy to integrate a log rotation package like
+[`gopkg.in/natefinch/lumberjack.v2`][lumberjack] as a `zapcore.WriteSyncer`.
+
+```go
+// lumberjack.Logger is already safe for concurrent use, so we don't need to
+// lock it.
+w := zapcore.AddSync(&lumberjack.Logger{
+ Filename: "/var/log/myapp/foo.log",
+ MaxSize: 500, // megabytes
+ MaxBackups: 3,
+ MaxAge: 28, // days
+})
+core := zapcore.NewCore(
+ zapcore.NewJSONEncoder(zap.NewProductionEncoderConfig()),
+ w,
+ zap.InfoLevel,
+)
+logger := zap.New(core)
+```
+
+## Extensions
+
+We'd love to support every logging need within zap itself, but we're only
+familiar with a handful of log ingestion systems, flag-parsing packages, and
+the like. Rather than merging code that we can't effectively debug and
+support, we'd rather grow an ecosystem of zap extensions.
+
+We're aware of the following extensions, but haven't used them ourselves:

+# :zap: zap [![GoDoc][doc-img]][doc] [![Build Status][ci-img]][ci] [![Coverage Status][cov-img]][cov]
+
+Blazing fast, structured, leveled logging in Go.
+
+## Installation
+
+`go get -u go.uber.org/zap`
+
+Note that zap only supports the two most recent minor versions of Go.
+
+## Quick Start
+
+In contexts where performance is nice, but not critical, use the
+`SugaredLogger`. It's 4-10x faster than other structured logging
+packages and includes both structured and `printf`-style APIs.
+
+```go
+logger, _ := zap.NewProduction()
+defer logger.Sync() // flushes buffer, if any
+sugar := logger.Sugar()
+sugar.Infow("failed to fetch URL",
+ // Structured context as loosely typed key-value pairs.
+ "url", url,
+ "attempt", 3,
+ "backoff", time.Second,
+)
+sugar.Infof("Failed to fetch URL: %s", url)
+```
+
+When performance and type safety are critical, use the `Logger`. It's even
+faster than the `SugaredLogger` and allocates far less, but it only supports
+structured logging.
+
+```go
+logger, _ := zap.NewProduction()
+defer logger.Sync()
+logger.Info("failed to fetch URL",
+ // Structured context as strongly typed Field values.
+ zap.String("url", url),
+ zap.Int("attempt", 3),
+ zap.Duration("backoff", time.Second),
+)
+```
+
+See the [documentation][doc] and [FAQ](FAQ.md) for more details.
+
+## Performance
+
+For applications that log in the hot path, reflection-based serialization and
+string formatting are prohibitively expensive — they're CPU-intensive
+and make many small allocations. Put differently, using `encoding/json` and
+`fmt.Fprintf` to log tons of `interface{}`s makes your application slow.
+
+Zap takes a different approach. It includes a reflection-free, zero-allocation
+JSON encoder, and the base `Logger` strives to avoid serialization overhead
+and allocations wherever possible. By building the high-level `SugaredLogger`
+on that foundation, zap lets users *choose* when they need to count every
+allocation and when they'd prefer a more familiar, loosely typed API.
+
+As measured by its own [benchmarking suite][], not only is zap more performant
+than comparable structured logging packages — it's also faster than the
+standard library. Like all benchmarks, take these with a grain of salt.[1](#footnote-versions)

+| logrus | 3017 ns/op | +1728% | 23 allocs/op
+| log15 | 3469 ns/op | +2002% | 20 allocs/op
+
+## Development Status: Stable
+
+All APIs are finalized, and no breaking changes will be made in the 1.x series
+of releases. Users of semver-aware dependency management systems should pin
+zap to `^1`.
+
+## Contributing
+
+We encourage and support an active, healthy community of contributors —
+including you! Details are in the [contribution guide](CONTRIBUTING.md) and
+the [code of conduct](CODE_OF_CONDUCT.md). The zap maintainers keep an eye on
+issues and pull requests, but you can also report any negative conduct to
+oss-conduct@uber.com. That email list is a private, safe space; even the zap
+maintainers don't have access, so don't hesitate to hold us to a high
+standard.

+
+// Package zap provides fast, structured, leveled logging.
+//
+// For applications that log in the hot path, reflection-based serialization
+// and string formatting are prohibitively expensive - they're CPU-intensive
+// and make many small allocations. Put differently, using json.Marshal and
+// fmt.Fprintf to log tons of interface{} makes your application slow.
+//
+// Zap takes a different approach. It includes a reflection-free,
+// zero-allocation JSON encoder, and the base Logger strives to avoid
+// serialization overhead and allocations wherever possible. By building the
+// high-level SugaredLogger on that foundation, zap lets users choose when
+// they need to count every allocation and when they'd prefer a more familiar,
+// loosely typed API.
+//
+// # Choosing a Logger
+//
+// In contexts where performance is nice, but not critical, use the
+// SugaredLogger. It's 4-10x faster than other structured logging packages and
+// supports both structured and printf-style logging. Like log15 and go-kit,
+// the SugaredLogger's structured logging APIs are loosely typed and accept a
+// variadic number of key-value pairs. (For more advanced use cases, they also
+// accept strongly typed fields - see the SugaredLogger.With documentation for
+// details.)
+//
+// sugar := zap.NewExample().Sugar()
+// defer sugar.Sync()
+// sugar.Infow("failed to fetch URL",
+// "url", "http://example.com",
+// "attempt", 3,
+// "backoff", time.Second,
+// )
+// sugar.Infof("failed to fetch URL: %s", "http://example.com")
+//
+// By default, loggers are unbuffered. However, since zap's low-level APIs
+// allow buffering, calling Sync before letting your process exit is a good
+// habit.
+//
+// In the rare contexts where every microsecond and every allocation matter,
+// use the Logger. It's even faster than the SugaredLogger and allocates far
+// less, but it only supports strongly-typed, structured logging.
+//
+// logger := zap.NewExample()
+// defer logger.Sync()
+// logger.Info("failed to fetch URL",
+// zap.String("url", "http://example.com"),
+// zap.Int("attempt", 3),
+// zap.Duration("backoff", time.Second),
+// )
+//
+// Choosing between the Logger and SugaredLogger doesn't need to be an
+// application-wide decision: converting between the two is simple and
+// inexpensive.
+//
+// logger := zap.NewExample()
+// defer logger.Sync()
+// sugar := logger.Sugar()
+// plain := sugar.Desugar()
+//
+// # Configuring Zap
+//
+// The simplest way to build a Logger is to use zap's opinionated presets:
+// NewExample, NewProduction, and NewDevelopment. These presets build a logger
+// with a single function call:
+//
+// logger, err := zap.NewProduction()
+// if err != nil {
+// log.Fatalf("can't initialize zap logger: %v", err)
+// }
+// defer logger.Sync()
+//
+// Presets are fine for small projects, but larger projects and organizations
+// naturally require a bit more customization. For most users, zap's Config
+// struct strikes the right balance between flexibility and convenience. See
+// the package-level BasicConfiguration example for sample code.
+//
+// More unusual configurations (splitting output between files, sending logs
+// to a message queue, etc.) are possible, but require direct use of
+// go.uber.org/zap/zapcore. See the package-level AdvancedConfiguration
+// example for sample code.
+//
+// # Extending Zap
+//
+// The zap package itself is a relatively thin wrapper around the interfaces
+// in go.uber.org/zap/zapcore. Extending zap to support a new encoding (e.g.,
+// BSON), a new log sink (e.g., Kafka), or something more exotic (perhaps an
+// exception aggregation service, like Sentry or Rollbar) typically requires
+// implementing the zapcore.Encoder, zapcore.WriteSyncer, or zapcore.Core
+// interfaces. See the zapcore documentation for details.
+//
+// Similarly, package authors can use the high-performance Encoder and Core
+// implementations in the zapcore package to build their own loggers.
+//
+// # Frequently Asked Questions
+//
+// An FAQ covering everything from installation errors to design decisions is
+// available at https://github.com/uber-go/zap/blob/master/FAQ.md.

+# 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 1.2, but preserves some behavior
+from 1.1 for backwards compatibility.
+
+Specifically, as of v3 of the yaml package:
+
+ - YAML 1.1 bools (_yes/no, on/off_) are supported as long as they are being
+ decoded into a typed bool value. Otherwise they behave as a string. Booleans
+ in YAML 1.2 are _true/false_ only.
+ - Octals encode and decode as _0777_ per YAML 1.1, rather than _0o777_
+ as specified in YAML 1.2, because most parsers still use the old format.
+ Octals in the _0o777_ format are supported though, so new files work.
+ - Does not support base-60 floats. These are gone from YAML 1.2, and were
+ actually never supported by this package as it's clearly a poor choice.
+
+and offers backwards
+compatibility with YAML 1.1 in some cases.
+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.v3*.
+
+To install it, run:
+
+ go get gopkg.in/yaml.v3
+
+API documentation
+-----------------
+
+If opened in a browser, the import path itself leads to the API documentation:
+
+ - [https://gopkg.in/yaml.v3](https://gopkg.in/yaml.v3)
+
+API stability
+-------------
+
+The package API for yaml v3 will remain stable as described in [gopkg.in](https://gopkg.in).
+
+
+License
+-------
+
+The yaml package is licensed under the MIT and Apache License 2.0 licenses.
+Please see the LICENSE file for details.
+
+
+Example
+-------
+
+```Go
+package main
+
+import (
+ "fmt"
+ "log"
+
+ "gopkg.in/yaml.v3"
+)
+
+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.
+//
+// Tokens:
+//
+// STREAM-START(utf-8)
+// TAG("!!","float")
+// SCALAR("3.14",double-quoted)
+// STREAM-END
+//
+// 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)
+// DOCUMENT-START
+// SCALAR("a single-quoted scalar",single-quoted)
+// DOCUMENT-START
+// SCALAR("a double-quoted scalar",double-quoted)
+// DOCUMENT-START
+// SCALAR("a literal scalar",literal)
+// DOCUMENT-START
+// SCALAR("a folded scalar",folded)
+// STREAM-END
+//
+// 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
