The +functions have syntax you are most likely already familiar with: + + spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2) + spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4) + spew.Println(myVar, myVar2) + spew.Fprintf(os.Stderr, "myVar1: %v -- myVar2: %+v", myVar1, myVar2) + spew.Fprintf(os.Stderr, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4) + +See the Index for the full list convenience functions. + +Sample Formatter Output + +Double pointer to a uint8: + %v: <**>5 + %+v: <**>(0xf8400420d0->0xf8400420c8)5 + %#v: (**uint8)5 + %#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5 + +Pointer to circular struct with a uint8 field and a pointer to itself: + %v: <*>{1 <*>} + %+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)} + %#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)} + %#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)} + +See the Printf example for details on the setup of variables being shown +here. + +Errors + +Since it is possible for custom Stringer/error interfaces to panic, spew +detects them and handles them internally by printing the panic information +inline with the output.

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 +``` + diff --git a/vendor/gopkg.in/yaml.v3/apic.go b/vendor/gopkg.in/yaml.v3/apic.go new file mode 100644 index 0000000..65846e6 --- /dev/null +++ b/vendor/gopkg.in/yaml.v3/apic.go @@ -0,0 +1,746 @@ +// +// Copyright (c) 2011-2019 Canonical Ltd +// Copyright (c) 2006-2010 Kirill Simonov +// +// Permission is hereby granted, free of charge, to any person obtaining a copy of +// this software and associated documentation files (the "Software"), to deal in +// the Software without restriction, including without limitation the rights to +// use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies +// of the Software, and to permit persons to whom the Software is furnished to do +// so, subject to the following conditions: +// +// The above copyright notice and this permission notice shall be included in all +// copies or substantial portions of the Software. +// +// THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +// IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +// FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

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.

See the -sections below for further details on formatting and configuration options. - -To dump a variable with full newlines, indentation, type, and pointer -information use Dump, Fdump, or Sdump: - spew.Dump(myVar1, myVar2, ...) - spew.Fdump(someWriter, myVar1, myVar2, ...) - str := spew.Sdump(myVar1, myVar2, ...) - -Alternatively, if you would prefer to use format strings with a compacted inline -printing style, use the convenience wrappers Printf, Fprintf, etc with -%v (most compact), %+v (adds pointer addresses), %#v (adds types), or -%#+v (adds types and pointer addresses): - spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2) - spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4) - spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2) - spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4) - -Configuration Options - -Configuration of spew is handled by fields in the ConfigState type. For -convenience, all of the top-level functions use a global state available -via the spew.Config global. - -It is also possible to create a ConfigState instance that provides methods -equivalent to the top-level functions. This allows concurrent configuration -options. See the ConfigState documentation for more details. - -The following configuration options are available: - * Indent - String to use for each indentation level for Dump functions. - It is a single space by default. A popular alternative is "\t". - - * MaxDepth - Maximum number of levels to descend into nested data structures. - There is no limit by default. - - * DisableMethods - Disables invocation of error and Stringer interface methods. - Method invocation is enabled by default. - - * DisablePointerMethods - Disables invocation of error and Stringer interface methods on types - which only accept pointer receivers from non-pointer variables. - Pointer method invocation is enabled by default. - - * DisablePointerAddresses - DisablePointerAddresses specifies whether to disable the printing of - pointer addresses. This is useful when diffing data structures in tests. - - * DisableCapacities - DisableCapacities specifies whether to disable the printing of - capacities for arrays, slices, maps and channels. This is useful when - diffing data structures in tests. - - * ContinueOnMethod - Enables recursion into types after invoking error and Stringer interface - methods. Recursion after method invocation is disabled by default. - - * SortKeys - Specifies map keys should be sorted before being printed. Use - this to have a more deterministic, diffable output. Note that - only native types (bool, int, uint, floats, uintptr and string) - and types which implement error or Stringer interfaces are - supported with other types sorted according to the - reflect.Value.String() output which guarantees display - stability. Natural map order is used by default. - - * SpewKeys - Specifies that, as a last resort attempt, map keys should be - spewed to strings and sorted by those strings. This is only - considered if SortKeys is true. - -Dump Usage - -Simply call spew.Dump with a list of variables you want to dump: - - spew.Dump(myVar1, myVar2, ...) - -You may also call spew.Fdump if you would prefer to output to an arbitrary -io.Writer. For example, to dump to standard error: - - spew.Fdump(os.Stderr, myVar1, myVar2, ...) - -A third option is to call spew.Sdump to get the formatted output as a string: - - str := spew.Sdump(myVar1, myVar2, ...) - -Sample Dump Output - -See the Dump example for details on the setup of the types and variables being -shown here. - - (main.Foo) { - unexportedField: (*main.Bar)(0xf84002e210)({ - flag: (main.Flag) flagTwo, - data: (uintptr) - }), - ExportedField: (map[interface {}]interface {}) (len=1) { - (string) (len=3) "one": (bool) true - } - } - -Byte (and uint8) arrays and slices are displayed uniquely like the hexdump -C -command as shown. - ([]uint8) (len=32 cap=32) { - 00000000 11 12 13 14 15 16 17 18 19 1a 1b 1c 1d 1e 1f 20 |............... | - 00000010 21 22 23 24 25 26 27 28 29 2a 2b 2c 2d 2e 2f 30 |!"#$%&'()*+,-./0| - 00000020 31 32 |12| - } - -Custom Formatter - -Spew provides a custom formatter that implements the fmt.Formatter interface -so that it integrates cleanly with standard fmt package printing functions. The -formatter is useful for inline printing of smaller data types similar to the -standard %v format specifier. - -The custom formatter only responds to the %v (most compact), %+v (adds pointer -addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb -combinations. Any other verbs such as %x and %q will be sent to the the -standard fmt package for formatting. In addition, the custom formatter ignores -the width and precision arguments (however they will still work on the format -specifiers not handled by the custom formatter). - -Custom Formatter Usage - -The simplest way to make use of the spew custom formatter is to call one of the -convenience functions such as spew.Printf, spew.Println, or spew.Printf. The -functions have syntax you are most likely already familiar with: - - spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2) - spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4) - spew.Println(myVar, myVar2) - spew.Fprintf(os.Stderr, "myVar1: %v -- myVar2: %+v", myVar1, myVar2) - spew.Fprintf(os.Stderr, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4) - -See the Index for the full list convenience functions. - -Sample Formatter Output - -Double pointer to a uint8: - %v: <**>5 - %+v: <**>(0xf8400420d0->0xf8400420c8)5 - %#v: (**uint8)5 - %#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5 - -Pointer to circular struct with a uint8 field and a pointer to itself: - %v: <*>{1 <*>} - %+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)} - %#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)} - %#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)} - -See the Printf example for details on the setup of variables being shown -here. - -Errors - -Since it is possible for custom Stringer/error interfaces to panic, spew -detects them and handles them internally by printing the panic information -inline with the output. Since spew is intended to provide deep pretty printing -capabilities on structures, it intentionally does not return any errors. -*/ -package spew diff --git a/vendor/github.com/davecgh/go-spew/spew/dump.go b/vendor/github.com/davecgh/go-spew/spew/dump.go deleted file mode 100644 index df1d582..0000000 --- a/vendor/github.com/davecgh/go-spew/spew/dump.go +++ /dev/null @@ -1,509 +0,0 @@ -/* - * Copyright (c) 2013-2016 Dave Collins - * - * Permission to use, copy, modify, and distribute this software for any - * purpose with or without fee is hereby granted, provided that the above - * copyright notice and this permission notice appear in all copies. - * - * THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES - * WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF - * MERCHANTABILITY AND FITNESS.

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.
