This project provides a composer
package with generic and vendor-specific normalizers for normalizing JSON documents.
Run
composer require ergebnis/json-normalizer
This project comes with
This project comes with the following generic normalizers:
Ergebnis\Json\Normalizer\CallableNormalizer
Ergebnis\Json\Normalizer\ChainNormalizer
Ergebnis\Json\Normalizer\FormatNormalizer
Ergebnis\Json\Normalizer\IndentNormalizer
Ergebnis\Json\Normalizer\JsonEncodeNormalizer
Ergebnis\Json\Normalizer\SchemaNormalizer
Ergebnis\Json\Normalizer\WithFinalNewLineNormalizer
Ergebnis\Json\Normalizer\WithoutFinalNewLineNormalizer
π‘ All of these normalizers implement the Ergebnis\Json\Normalizer\Normalizer
.
When you want to normalize a JSON file with a callable
, you can use the CallableNormalizer
.
<?php
declare(strict_types=1);
use Ergebnis\Json\Json;
use Ergebnis\Json\Normalizer;
$encoded = <<<'JSON'
{
"name": "Andreas MΓΆller",
"url": "https://localheinz.com"
}
JSON;
$json = Json::fromString($encoded);
$callable = function (Json $json): Json {
$decoded = $json->decoded();
foreach (get_object_vars($decoded) as $name => $value) {
if ('https://localheinz.com' !== $value) {
continue;
}
$decoded->{$name} .= '/open-source/';
}
return Json::fromString(json_encode($decoded));
};
$normalizer = new Normalizer\CallableNormalizer($callable);
$normalized = $normalizer->normalize($json);
The normalized version will now have the callable applied to it.
When you want to apply multiple normalizers in a chain, you can use the ChainNormalizer
.
<?php
declare(strict_types=1);
use Ergebnis\Json\Json;
use Ergebnis\Json\Normalizer;
use Ergebnis\Json\Printer;
$encoded = <<<'JSON'
{
"name": "Andreas MΓΆller",
"url": "https://localheinz.com"
}
JSON;
$json = Json::fromString($encoded);
$indent = Normalizer\Format\Indent::fromString(' ');
$jsonEncodeOptions = Normalizer\Format\JsonEncodeOptions::fromInt(JSON_UNESCAPED_UNICODE | JSON_UNESCAPED_SLASHES);
$normalizer = new Normalizer\ChainNormalizer(
new Normalizer\JsonEncodeNormalizer($jsonEncodeOptions),
new Normalizer\IndentNormalizer(
$indent,
new Printer\Printer()
),
new Normalizer\WithFinalNewLineNormalizer()
);
$normalized = $normalizer->normalize($json);
The normalized version will now contain the result of applying all normalizers in a chain, one after another.
π‘ Be careful with the order of the normalizers, as one normalizer might override changes a previous normalizer applied.
When you want to normalize a JSON file with a formatting, you can use the FormatNormalizer
.
<?php
declare(strict_types=1);
use Ergebnis\Json\Json;
use Ergebnis\Json\Normalizer;
use Ergebnis\Json\Printer;
$encoded = <<<'JSON'
{
"name": "Andreas MΓΆller",
"emoji": "π€",
"url": "https://localheinz.com"
}
JSON;
$json = Json::fromString($encoded);
$format = Normalizer\Format\Format::create(
Normalizer\Format\Indent::fromString(' '),
Normalizer\Format\JsonEncodeOptions::fromInt(JSON_UNESCAPED_UNICODE | JSON_UNESCAPED_SLASHES),
Normalizer\Format\NewLine::fromString("\r\n")
true
);
$normalizer = new Normalizer\FormatNormalizer(
new Printer\Printer(),
$format,
);
$normalized = $normalizer->normalize($json);
The normalized version will now have formatting applied according to $format
.
When you need to adjust the indentation of a JSON file, you can use the IndentNormalizer
.
<?php
declare(strict_types=1);
use Ergebnis\Json\Json;
use Ergebnis\Json\Normalizer;
use Ergebnis\Json\Printer;
$encoded = <<<'JSON'
{
"name": "Andreas MΓΆller",
"url": "https://localheinz.com"
}
JSON;
$json = Json::fromString($encoded);
$indent = Normalizer\Format\Indent::fromString(' ');
$normalizer = new Normalizer\IndentNormalizer(
$indent,
new Printer\Printer()
);
$normalized = $normalizer->normalize($json);
The normalized version will now be indented with 2 spaces.
When you need to adjust the encoding of a JSON file, you can use the JsonEncodeNormalizer
.
<?php
declare(strict_types=1);
use Ergebnis\Json\Json;
use Ergebnis\Json\Normalizer;
$encoded = <<<'JSON'
{
"name": "Andreas M\u00f6ller",
"url": "https:\/\/localheinz.com"
}
JSON;
$json = Json::fromString($encoded);
$jsonEncodeOptions = Normalizer\Format\JsonEncodeOptions::fromInt(JSON_UNESCAPED_SLASHES | JSON_UNESCAPED_UNICODE);
$normalizer = new Normalizer\JsonEncodeNormalizer($jsonEncodeOptions);
$normalized = $normalizer->normalize($json);
The normalized version will now be encoded with $jsonEncodeOptions
.
π‘ For reference, see json_encode()
and the corresponding JSON constants.
When you want to rebuild a JSON file according to a JSON schema, you can use the SchemaNormalizer
.
Let's assume the following schema
{
"type": "object",
"additionalProperties": true,
"properties": {
"name" : {
"type" : "string"
},
"role" : {
"type" : "string"
}
}
}
exists at /schema/example.json
.
<?php
declare(strict_types=1);
use Ergebnis\Json\Normalizer;
use Ergebnis\Json\Pointer;
use Ergebnis\Json\SchemaValidator;
use JsonSchema\SchemaStorage;
$encoded = <<<'JSON'
{
"url": "https://localheinz.com",
"name": "Andreas MΓΆller",
"open-source-projects": {
"ergebnis/data-provider": {
"downloads": {
"total": 2,
"monthly": 1
}
},
"ergebnis/composer-normalize": {
"downloads": {
"total": 5,
"monthly": 2
}
}
}
}
JSON;
$json = Json::fromString($encoded);
$normalizer = new Normalizer\SchemaNormalizer(
'file:///schema/example.json',
new SchemaStorage(),
new SchemaValidator\SchemaValidator(),
Pointer\Specification::never()
);
$normalized = $normalizer->normalize($json);
The normalized version will now be structured according to the JSON schema (in this simple case, properties will be reordered as found in the schema and additional properties will be ordered by name). Internally, the SchemaNormalizer
uses justinrainbow/json-schema
to resolve schemas, as well as to ensure (before and after normalization) that the JSON document is valid.
If you have properties that you do not want to be reordered, you can use a Pointer\Specification
to specify which properties should not be reordered.
<?php
declare(strict_types=1);
use Ergebnis\Json\Normalizer;
use Ergebnis\Json\Pointer;
use Ergebnis\Json\SchemaValidator;
use JsonSchema\SchemaStorage;
$encoded = <<<'JSON'
{
"url": "https://localheinz.com",
"name": "Andreas MΓΆller",
"open-source-projects": {
"ergebnis/data-provider": {
"downloads": {
"total": 2,
"monthly": 1
}
},
"ergebnis/composer-normalize": {
"downloads": {
"total": 5,
"monthly": 2
}
}
}
}
JSON;
$json = Json::fromString($encoded);
$normalizer = new Normalizer\SchemaNormalizer(
'file:///schema/example.json',
new SchemaStorage(),
new SchemaValidator\SchemaValidator(),
Pointer\Specification::equals(Pointer\JsonPointer::fromJsonString('/open-source-projects'))
);
$normalized = $normalizer->normalize($json);
π‘ For more information about JSON schema, visit json-schema.org.
When you want to ensure that a JSON file has a single final new line, you can use the WithFinalNewLineNormalizer
.
<?php
declare(strict_types=1);
use Ergebnis\Json\Normalizer;
$encoded = <<<'JSON'
{
"name": "Andreas MΓΆller",
"url": "https://localheinz.com"
}
JSON;
$json = Json::fromString($encoded);
$normalizer = new Normalizer\WithFinalNewLineNormalizer();
$normalized = $normalizer->normalize($json);
The normalized version will now have a single final new line.
When you want to ensure that a JSON file does not have a final new line, you can use the WithoutFinalNewLineNormalizer
.
<?php
declare(strict_types=1);
use Ergebnis\Json\Normalizer;
$encoded = <<<'JSON'
{
"name": "Andreas MΓΆller",
"url": "https://localheinz.com"
}
JSON;
$json = Json::fromString($encoded);
$normalizer = new Normalizer\WithoutFinalNewLineNormalizer();
$normalized = $normalizer->normalize($json);
The normalized version will now not have a final new line or any whitespace at the end.
This project comes with the following vendor-specific normalizers:
The Vendor\Composer\ComposerJsonNormalizer
can be used to normalize a composer.json
file according to its underlying JSON schema.
It composes the following normalizers:
Ergebnis\Composer\Json\Normalizer\Vendor\Composer\BinNormalizer
Ergebnis\Composer\Json\Normalizer\Vendor\Composer\ConfigHashNormalizer
Ergebnis\Composer\Json\Normalizer\Vendor\Composer\PackageHashNormalizer
Ergebnis\Composer\Json\Normalizer\Vendor\Composer\RepositoriesHashNormalizer
Ergebnis\Composer\Json\Normalizer\Vendor\Composer\VersionConstraintNormalizer
Ergebnis\Composer\Json\Normalizer\Vendor\WithFinalNewLineNormalizer
When composer.json
contains an array of scripts in the bin
section, the Vendor\Composer\BinNormalizer
will sort the elements of the bin
section by value in ascending order.
When composer.json
contains configuration in the config
section, the Vendor\Composer\ConfigHashNormalizer
will sort the content of these sections by key in ascending order.
The allow-plugins
and preferred-install
configuration options support keys with wildcards and require special handling.
When these keys do not use wildcards, then these keys are sorted in ascending order. When these keys use wildcards, these keys are sorted when the wildcards are at the end of package names. Due to internal implementation details of the wildcard feature within composer
, sorting keys with wildcards in the middle is not feasible.
When composer.json
contains any configuration in the
sections, the Vendor\Composer\PackageHashNormalizer
will sort the packages in these sections.
π‘ This transfers the behaviour from using the --sort-packages
or sort-packages
configuration flag in require
and require-dev
to other sections.
When composer.json
contains any configuration in the
section, the Vendor\Composer\RepositoriesHashNormalizer
will sort the repositories listed in the exclude
and only
properties of repositories.
When composer.json
contains version constraints in the
sections, the Vendor\Composer\VersionConstraintNormalizer
will ensure that
-
all version constraints are trimmed
