protected mixed DEFAULT_TOTAL = 100

Percent completion is derived from progress/total

DEFAULT_WIDTH

Default value for progress bar width

protected mixed DEFAULT_WIDTH = 80

Properties

$_configInitialized

Whether the config property has already been configured with defaults

protected bool $_configInitialized = false

$_defaultConfig

Default config for this helper.

protected array<string, mixed> $_defaultConfig = []

$_progress

The current progress.

protected float|int $_progress = 0

$_total

The total number of 'items' to progress through.

protected int $_total = self::DEFAULT_TOTAL

$_width

protected int $_width = self::DEFAULT_WIDTH

Methods

__construct()

Constructor.

public __construct(ConsoleIo $io[, array<string, mixed> $config = [] ]) : mixed
Parameters
$io : ConsoleIo

The ConsoleIo instance to use.

$config : array<string, mixed> = []

The settings for this helper.

configShallow()

Merge provided config with existing config. Unlike `config()` which does a recursive merge for nested keys, this method does a simple merge.

public configShallow(array<string, mixed>|string $key[, mixed|null $value = null ]) : $this

Setting a specific value:

$this->configShallow('key', $value);

Setting a nested value:

$this->configShallow('some.nested.key', $value);

Updating multiple config settings at the same time:

$this->configShallow(['one' => 'value', 'another' => 'value']);
Parameters
$key : array<string, mixed>|string

The key to set, or a complete array of configs.

$value : mixed|null = null

The value to set.

Return values
$this

draw()

Render the progress bar based on the current state.

public draw() : $this
Return values
$this

getConfig()

Returns the config.

public getConfig([string|null $key = null ][, mixed $default = null ]) : mixed

Usage

Reading the whole config:

$this->getConfig();

Reading a specific value:

$this->getConfig('key');

Reading a nested value:

$this->getConfig('some.nested.key');

Reading with default value:

$this->getConfig('some-key', 'default-value');
Parameters
$key : string|null = null

The key to get or null for the whole config.

$default : mixed = null

The return value when the key does not exist.

Return values
mixed —

Configuration data at the named key or null if the key does not exist.

getConfigOrFail()

Returns the config for this specific key.

public getConfigOrFail(string $key) : mixed

The config value for this key must exist, it can never be null.

Parameters
$key : string

The key to get.

public increment([float|int $num = 1 ]) : $this
Parameters
$num : float|int = 1

The amount of progress to advance by.

Return values
$this

init()
