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. + +## Contributing +Please feel free to submit issues, fork the repository and send pull requests! diff --git

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 0000000000..65846e6749 --- /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.
