The build command will build a new PHAR based on a variety of settings.

This command relies on a configuration file for loading PHAR packaging settings. If a configuration file is not specified through the --config|-c option, one of the following files will be used (in order): box.json, box.json.dist. If no configuration file is found, Box will proceed with the default settings.

The configuration file is a JSON object saved to a file. Note that all settings are optional. If a setting is set to null, then its default value will be picked and is strictly equivalent to not setting the value.

Base-path (`base-path`)

The base-path (string|null) setting is used to specify where all of the relative file paths should resolve to. This does not, however, alter where the built PHAR will be stored (see: output).

If set to null or not specified, the base path used is the directory containing the configuration file when a specific configuration file is given or the current working directory otherwise.

Main (`main`)

The main (string|false|null) setting is used to specify the file (relative to base-path) that will be run when the PHAR is executed from the command line (To not confuse with the stub which is the PHAR bootstrapping file).

When you have a main script file that can be used as a stub, you can disable the main script by setting it to false:

{
    "stub": "bin/acme.php",
    "main": false
}

When the parameter is not given or set to null, Box tries to guess the binary of the application with the composer.json file. If the Composer bin is set, Box will pick the first value provided. Otherwise it will fallback on the PHAR default file used which is index.php.

The main file contents is processed by the compactors as the other files.

If the main file starts with a shebang line (#!), it will be automatically removed (the shebang line goes in the stub for a PHAR and is configured by the shebang setting).

Output (`output`)

The output (string|null) setting specifies the file name and path of the newly built PHAR. If the value of the setting is not an absolute path, the path will be relative to the base path.

If not provided or set to null, the default value used will based on the main. For example if the main file is bin/acme.php or bin/acme then the output will be bin/acme.phar.

Permissions (`chmod`)

The chmod (string|null) setting is used to change the file permissions of the newly built PHAR. The string contains an octal value e.g. 0750. By default the permissions of the created PHAR are unchanged so it should be 0644.

Check the following link for more on the possible values.

Check requirements (`check-requirements`)

The check requirements setting (boolean|null, default true) is used to allow the PHAR to check for the application constraint before running. See more information about it here. If not set or set to null, then the requirement checker will be added. Note that this is true only if either the composer.json or composer.lock could have been found.

!!! Warning this check is still done within the PHAR. As a result, if the required extension to open the PHAR due to the compression algorithm is not loaded, a hard failure will still appear: the requirement checker cannot be executed before that.

Including files

There is two ways to include files. The first one is to not be picky about which files are shipped in the PHAR. If you omit any of the following options, all the files found. The base directory used to find the files is either the configuration file if one is used/specified or the current working directory otherwise. The blacklist setting can be used to filter out some files from that selection.

If you however want a more granular selection, you can use a combination of the following options: files, files-bin, directories, directories-bin, finder, finder-bin, blacklist.

If directories or finder is set (this includes empty values), Box will no longer try to guess which files should be included or not (unless you force the auto-discovery) and will give you full control on it instead.

!!! Note By default, dev dependencies are excluded for both strategies. However if you still which to include a file or directory from a dev dependency, you can do so by adding it via one of the following setting: files, files-bin, directories or directories-bin.

!!! Warning binary files are added before regular files. As a result if a file is found in both regular files and binary files, the regular file will take precedence.

Force auto-discovery (`force-autodiscovery`)

The force-autodiscovery (bool default false) setting forces Box to attempt to find which files to include even though you are using the directories or finder setting.

When Box tries to find which files to include, it may remove some files such as readmes or test files. If however you are using the directories or finder, Box will append the found files to the ones you listed.

Files (`files` and `files-bin`)

The files (string[]|null default []) setting is a list of files paths relative to base-path unless absolute. Each file will be processed by the compactors, have their placeholder values replaced (see: replacements) and added to the PHAR.

This setting is not affected by the blacklist setting.

files-bin is analogue to files except the files are added to the PHAR unmodified. This is suitable for the files such as images, those that contain binary data or simply a file you do not want to alter at all despite using compactors.

!!! Warning Symlinks are not followed/supported.

Directories (`directories` and `directories-bin`)

The directories (string[]|null default []) setting is a list of directory paths relative to base-path. All files will be processed by the compactors, have their placeholder values replaced (see: replacements) and added to the PHAR.

Files listed in the blacklist will not be added to the PHAR.

directories-bin is analogue to directories except the files are added to the PHAR unmodified. This is suitable for the files such as images, those that contain binary data or simply a file you do not want to alter at all despite using compactors.

!!! Warning Setting the key directories (regardless of its value), will disable the file auto-discovery. If you want to keep it, check the force the auto-discovery setting.

!!! Warning By default Box excludes some files (e.g. dot files, readmes & co). This is done in order to attempt to reduce the final PHAR size. There is at the moment no way to disable this (maybe this could be done via a new setting) but it remains possible to include them via files, files-bin, directories-bin or your own finder or finder-bin.

!!! Warning Symlinks are not followed/supported.

Finder (`finder` and `finder-bin`)

The finder (object[]|null default []) setting is a list of JSON objects. Each object (key, value) tuple is a (method, arguments) of the Symfony Finder used by Box. If an array of values is provided for a single key, the method will be called once per value in the array.

Note that the paths specified for the in method are relative to base-path and that the finder will account for the files registered in the blacklist.

finder-bin is analogue to finder except the files are added to the PHAR unmodified. This is suitable for the files such as images, those that contain binary data or simply a file you do not want to alter at all despite using compactors.

!!! Warning Setting the key finder (regardless of its value), will disable the file auto-discovery. If you want to keep it, check the force the auto-discovery setting.

!!! Warning Symlinks are not followed/supported.

Example:

{
    "finder": [
          {
              "notName": "/LICENSE|.*\\.md|.*\\.dist|Makefile|composer\\.json|composer\\.lock/",
              "exclude": [
                  "doc",
                  "test",
                  "test_old",
                  "tests",
                  "Tests",
                  "vendor-bin"
              ],
              "in": "vendor"
          },
          {
              "name": "composer.json",
              "in": "."
          }
    ]
}

Blacklist (`blacklist`)

The blacklist (string[]|null default []) setting is a list of files that must not be added. The files blacklisted are the ones found using the other available configuration settings: files, files-bin, directories, directories-bin, finder, finder-bin.

Note that all the blacklisted paths are relative to the settings configured above. For example if you have the following file structure:

project/
├── box.json.dist
├── A/
|   ├── A00
|   └── A01
└── B/
    ├── B00
    ├── B01
    └── A/
        └── BA00

With:

{
    # other non file related settings

    "blacklist": [
        "A"
    ]
}

Box will try to collect all the files found in project (cf. Including files) but will exclude A/ and `B/A resulting in the following files being collected:

project/
├── box.json.dist
└── B/
    ├── B00
    └── B01

If you want a more granular blacklist leverage, use the Finders configuration instead.

Excluding the Composer files (`exclude-composer-files`)

The exclude-composer-files (boolean|null, default true) setting will result in removing the Composer files composer.json, composer.lock and vendor/composer/installed.json if they are found regardless of whether or not they were found by Box alone or explicitly included.

Excluding dev files (`exclude-dev-files`)

The exclude-dev-files (bool default true) setting will, when enabled, cause Box to attempt to exclude the files belonging to dev only packages. For example for the given project:

composer.json

{
    "require": {
        "beberlei/assert": "^3.0"
    },
    "require-dev": {
        "bamarni/composer-bin-plugin": "^1.2"
    }
}

The vendor directory will have beberlei/assert and bamarni/composer-bin-plugin. If exclude-dev-files is not disabled, the bamarni/composer-bin-plugin package will be removed from the PHAR.

This setting will automatically be disabled when dump-autoload is disabled. Indeed, otherwise some files will not be shipped in the PHAR but may still appear in the Composer autoload classmap, resulting in an autoloading error.

Map (`map`)

The map (object[] default []) setting is used to change where some (or all) files are stored inside the PHAR. The key is a beginning of the relative path that will be matched against the file being added to the PHAR. If the key is a match, the matched segment will be replaced with the value. If the key is empty, the value will be prefixed to all paths (except for those already matched by an earlier key).

For example, with the following configuration excerpt:

{
  "map": [
    { "my/test/path": "src/Test" },
    { "": "src/Another" }
  ]
}

with the following files added to the PHAR:

my/test/path/file.php
my/test/path/some/other.php
my/test/another.php

the above files will be stored with the following paths in the PHAR:

src/Test/file.php
src/Test/some/other.php
src/Another/my/test/another.php

Stub

The PHAR stub file is the PHAR bootstrapping file, i.e. the very first file executed whenever the PHAR is executed. It usually contains things like the PHAR configuration and executing the main script file.

The default PHAR stub file can be used but Box also propose a couple of options to customize the stub used.

Stub (`stub`)

The stub (string|boolean|null default true) setting is used to specify the location of a stub file or if one should be generated:

string: Path to the stub file will be used as is inside the PHAR
true (default): A new stub will be generated
false: The default stub used by the PHAR class will be used

If a custom stub file is provided, none of the other options (shebang, [intercept][intercept] and alias) are used.

Shebang (`shebang`)

The shebang (string|false|null) setting is used to specify the shebang line used when generating a new stub. By default, this line is used:

#!/usr/bin/env php

The shebang line can be removed altogether if set to false.

Intercept (`intercept`)

The intercept (boolean|null default false) setting is used when generating a new stub. If setting is set to true, the Phar::interceptFileFuncs() method will be called in the stub.

Alias (`alias`)

The alias (string|null) setting is used when generating a new stub to call the Phar::mapPhar(). This makes it easier to refer to files in the PHAR and ensure the access to internal files will always work regardless of the location of the PHAR on the file system.

If no alias is provided, a generated unique name will be used for it in order to map the main file. Note that this may have undesirable effects if you are using the generated stub

Example:

// .phar.stub

#!/usr/bin/env php
<?php

if (class_exists('Phar')) {
    Phar::mapPhar('alias.phar');
    require 'phar://' . __FILE__ . '/index.php';
}

__HALT_COMPILER(); ?>


// index.php
<?php

if (!isset($GLOBALS['EXECUTE'])) {
    $GLOBALS['EXECUTE'] = true;
}

// On the first execution, we require that other file while
// on the second we will echo "Hello world!"
if ($GLOBALS['EXECUTE']) {
    require 'foo.php';
} else {
    echo 'Hello world!';
}


// foo.php
<?php

$GLOBALS['EXECUTE'] = false;

// Notice how we are using `phar://alias.phar` here. This will
// always work. This allows you to not have to find where the file
// is located in the PHAR neither finding the PHAR file path
require 'phar://alias.phar/index.php';

If you are using the default stub, Phar::setAlias() will be used. Note however that this will behave slightly differently.

Example:

<?php

$phar = new Phar('index.phar'); // Warning: creating a Phar instance results in *loading* the file. From this point, the
                                // PHAR stub file has been loaded and as a result, if the PHAR had an alias the alias
                                // will be registered.
$phar->setAlias('foo.phar');
$phar->addFile('LICENSE');

file_get_contents('phar://foo.phar/LICENSE'); // Will work both inside the PHAR but as well as outside as soon as the
                                              // PHAR is loaded in-memory.

As you can see above, loading a PHAR which has an alias result in a non-negligible side effect. A typical case where this might be an issue can be illustrated with box itself. For its end-to-end test, the process is along the lines of:

1. Build a PHAR box.phar from the source code
1. Build the PHAR box.phar from the source again but using the previous PHAR this time

If an alias box-alias.phar was registered for both for example, the building would fail. Indeed when building the second PHAR, the first PHAR is loaded which loads the alias box-alias.phar. When creating the second PHAR, box would try to register the alias box-alias.phar to that new PHAR but as the alias is already used, an error will be thrown.

Banner (`banner`)

The banner (string|string[]|false|null) setting is the banner comment that will be used when a new stub is generated. The value of this setting must not already be enclosed within a comment block as it will be automatically done for you.

For example Custom banner will result in the stub file:

/*
 * Custom banner
 */

An array of strings can be used for multilines banner:

{
    "banner": [
          "This file is part of the box project.",
          "",
          "(c) Kevin Herrera <kevin@herrera.io>",
          "Théo Fidry <theo.fidry@gmail.com>",
          "",
          "This source file is subject to the MIT license that is bundled",
          "with this source code in the file LICENSE."
    ]
}

Will result in:

/*
 * This file is part of the box project.
 *
 * (c) Kevin Herrera <kevin@herrera.io>
 *     Théo Fidry <theo.fidry@gmail.com>
 *
 * This source file is subject to the MIT license that is bundled
 * with this source code in the file LICENSE.
 */

By default, the Box banner is used. If set to false, no banner at all will be used.

The content of this value is discarded if banner-file is set.

Banner file (`banner-file`)

The banner-file (string|null ignored by default) setting is like banner, except it is a path (relative to the base path) to the file that will contain the comment.

Like banner, the comment must not already be enclosed in a comment block.

If this parameter is set to a different value than null, then the value of banner will be discarded.

Dumping the Composer autoloader (`dump-autoload`)

The dump-autoload (boolean|null, default true) setting will result in Box dump the Composer autoload with the classmap authoritative mode and the --no-dev option which disables the autoload-dev rules. This is however done only if a composer.json file could be found. If a composer.lock file is found as well, the file vendor/composer/installed.json will be required too.

The dumping of the autoloader will be ignored if the composer.json file could not be found.

The autoloader is dumped at the end of the process to ensure it will take into account the eventual modifications done by the compactors process.

Compactors (`compactors`)

The compactors (string[]|null default []) setting is a list of file contents compacting classes that must be registered. A file compacting class is used to reduce the size of a specific file type. The following is a simple example:

<?php

namespace Acme;

use KevinGH\Box\Compactor\Compactor;

class MyCompactor implements Compactor
{
    /**
     * {@inheritdoc}
     */
    public function compact(string $file, string $contents): string
    {
        if (preg_match('/\.txt/', \$file)) {
            return trim($contents);
        }

        return $contents;
    }
}

The following compactors are included with Box:

KevinGH\Box\Compactor\Json: compress JSON files
KevinGH\Box\Compactor\Php: strip down classes from phpdocs & comments
KevinGH\Box\Compactor\PhpScoper: isolate the code using PHP-Scoper

The effects of the compactors and replacement values can be tested with the process command ✨.

Annotations (`annotations`)

The annotations (boolean|object|null default true) setting is used to enable compacting annotations in PHP source code.

This setting is only taken into consideration if the KevinGH\Box\Compactor\Php compactor is enabled.

By default, it removes all non real-like annotations from the PHP code. See the following example:

Original code

<?php

/**
 * Function comparing the two given values
 *
 * @param int $x
 * @param int $y
 *
 * @return int
 *
 * @author Théo Fidry
 * @LICENSE MIT
 *
 * @Acme(type = "function")
 */
function foo($x, $y): int {
    // Compare the two values
    return $x <=> $y;
}

Compacted code

<?php

/**
@Acme(type="function")










*/
function foo($x, $y): int {

 return $x <=> $y;
}

Note that the empty line returns are on purpose: it is to keep the same line number for the files between your source code and the code bundled in the PHAR.

If you wish to keep all annotations, you can disable the annotations like so:

{
    "annotations": false
}

For a more granular list, you can manually configure the list of annotations you wish to ignore:

{
    "annotations": {
        "ignore": [
            "author",
            "package",
            "version",
            "see"
        ]
    }
}

PHP-Scoper (`php-scoper`)

The PHP-Scoper setting (string|null default scoper.inc.php) points to the path to the PHP-Scoper configuration file. For more documentation regarding PHP-Scoper, you can head to PHAR code isolation or PHP-Scoper official documentation.

Note that this setting is used only if the compactor KevinGH\Box\Compactor\PhpScoper is registered.

Compression algorithm (`compression`)

The compression (string|null default NONE) setting is the compression algorithm to use when the PHAR is built. The compression affects the individual files within the PHAR and not the PHAR as a whole (Phar::compressFiles()). The following is a list of the signature algorithms available:

GZ (the most efficient most of the time)
BZ2
NONE (default)

!!! Warning Be aware that if compressed, the PHAR will required the appropriate extension (zlib for GZ and bz2 for BZ2) to execute the PHAR. Without it, PHP will not be able to open the PHAR at all.

Security

Signing algorithm (`algorithm`)

The algorithm (string|null default SHA1) setting is the signing algorithm to use when the PHAR is built (Phar::setSignatureAlgorithm()). The following is a list of the signature algorithms available:

MD5
SHA1
SHA256
SHA512
OPENSSL

By default PHARs are SHA1 signed.

The OPENSSL algorithm will require to provide a key.

The private key (`key`)

The key (string|null default null) setting is used to specify the path to the private key file. The private key file will be used to sign the PHAR using the OPENSSL signature algorithm (see Signing algorithm) and the setting will be completely ignored otherwise. If an absolute path is not provided, the path will be relative to the current working directory.

The private key password (`key-pass`)

The private key password (string|boolean|null default null) setting is used to specify the pass-phrase for the private key. If a string is provided, it will be used as is as the pass-phrase. If true is provided, you will be prompted for the passphrase unless you are not in an interactive environment.

This setting will be ignored if no key has been provided.

Metadata (`metadata`)

The metadata (any default none) setting can be any value. This value will be stored as metadata that can be retrieved from the built PHAR (Phar::getMetadata()).

If you specify a callable (as a string), it will be evaluated without any arguments.

For example, if you take the following code:

<?php
# callable_script.php
class MyCallbacks
{
    public static function generateMetadata()
    {
        return ['application_version' => '1.0.0-dev'];
    }
}

With the configuration excerpt:

{
    "metadata": "MyCallbacks::generateMetadata"
}

Then the Phar::getMetadata() will return ['application_version' => '1.0.0-dev'] array.

CAUTION: Your callable function must be readable by your autoloader.

That means, for Composer, in previous example, we require to have such kind of declaration in your composer.json file.

{
    "autoload": {
        "files": ["/path/to/your/callable_script.php"]
    }
}

Replaceable placeholders

This feature allows you to set placeholders in your code which will be replaced by different values by Box when building the PHAR.

For example, if you take the following code:

<?php

class Application
{
    public function getVersion(): string
    {
        return '@git_commit_short@';
    }
}

With the configuration excerpt:

{
    "git-commit-short": "git_commit_short"
}

Then the actual code shipped in the PHAR will be:

<?php

class Application
{
    public function getVersion(): string
    {
        return 'a6c5d93';
    }
}

The @ is the default value of the sigil which is the placeholders delimited and git-commit-short is one of the built in placeholder. Box ships a few buit-in placeholders which you can find bellow, but you can also specify any replacement value via the replacements setting.

The effects of the compactors and replacement values can be tested with the process command ✨.

Replacements (`replacements`)

The replacements (object|null, default {}) setting is a map of placeholders (as keys) and their values. The placeholders are replaced in all non-binary files with the specified values.

For example:

{
    "replacements": {
        "foo": "bar"
    }
}

Will result in the string @foo@ in your code to be replaced by 'bar'. The delimiter @ being the sigil.

Replacement sigil (`replacement-sigil`)

The replacement sigil (string|null default @) is the character or chain of characters used to delimit the placeholders. See the @replacements setting for examples of placeholders.

Datetime placeholder (`datetime`)

The datetime (string|null default null) setting is the name of a placeholder value that will be replaced in all non-binary files by the current datetime. If no value is given (null) then this placeholder will be ignored.

Example value the placeholder will be replaced with: 2015-01-28 14:55:23 CEST

The format of the date used is defined by the datetime-format setting.

Datetime placeholder format (`datetime-format`)

The datetime format placeholder (string|null, default Y-m-d H:i:s T) setting accepts a valid PHP date format. It can be used to change the format for the datetime setting.

Pretty git tag placeholder (`git`)

The git tag placeholder (string|null default null) setting is the name of a placeholder value that will be replaced in all non-binary files by the current git tag of the repository.

Example of value the placeholder will be replaced with:

2.0.0 on an exact tag match
2.0.0@e558e33 on a commit following a tag

Git commit placeholder (`git-commit`)

The git commit (string|null default null) setting is the name of a placeholder value that will be replaced in all non-binary files by the current git commit hash of the repository.

Example of value the placeholder will be replaced with: e558e335f1d165bc24d43fdf903cdadd3c3cbd03

Short git commit placeholder (`git-commit-short`)

The short git commit (string|null default null) setting is the name of a placeholder value that will be replaced in all non-binary files by the current git short commit hash of the repository.

Example of value the placeholder will be replaced with: e558e33

Git tag placeholder (`git-tag`)

The git tag placeholder (string|null default null) setting is the name of a placeholder value that will be replaced in all non-binary files by the current git tag of the repository.

Example of value the placeholder will be replaced with:

2.0.0 on an exact tag match
2.0.0-2-ge558e33 on a commit following a tag

Git version placeholder (`git-version`)

The git version (string|null default null) setting is the name of a placeholder value that will be replaced in all non-binary files by the one of the following (in order):

The git repository's most recent tag.
The git repository's current short commit hash.

The short commit hash will only be used if no tag is available.
