StreamOutput extends Output
in package

StreamOutput writes the output to a given stream.

Usage:

$output = new StreamOutput(fopen('php://stdout', 'w'));

As StreamOutput can use any stream, you can also use a file:

$output = new StreamOutput(fopen('/path/to/output.log', 'a', false));

Methods

__construct()

public __construct(resource $stream[, int $verbosity = self::VERBOSITY_NORMAL ][, bool|null $decorated = null ][, OutputFormatterInterface|null $formatter = null ]) : mixed
Parameters
$stream : resource

A stream resource

$verbosity : int = self::VERBOSITY_NORMAL

The verbosity level (one of the VERBOSITY constants in OutputInterface)

$decorated : bool|null = null

Whether to decorate messages (null for auto-guessing)

$formatter : OutputFormatterInterface|null = null

Output formatter instance (null to use default OutputFormatter)

Tags
throws
InvalidArgumentException

When first argument is not a real stream

getStream()

Gets the stream attached to this StreamOutput instance.

public getStream() : resource
Return values
resource —

A stream resource

getVerbosity()

Gets the current verbosity of the output.

public getVerbosity() : int
Return values
int —

The current level of verbosity (one of the VERBOSITY constants)

isDebug()

Returns whether verbosity is debug (-vvv).

public isDebug() : bool
Return values
bool —

true if verbosity is set to VERBOSITY_DEBUG, false otherwise

isDecorated()

Gets the decorated flag.

public isDecorated() : bool
Return values
bool —

true if the output will decorate messages, false otherwise

isQuiet()

Returns whether verbosity is quiet (-q).

public isQuiet() : bool
Return values
bool —

true if verbosity is set to VERBOSITY_QUIET, false otherwise

isVerbose()

Returns whether verbosity is verbose (-v).

public isVerbose() : bool
Return values
bool —

true if verbosity is set to VERBOSITY_VERBOSE, false otherwise

isVeryVerbose()

Returns whether verbosity is very verbose (-vv).

public isVeryVerbose() : bool
Return values
bool —

true if verbosity is set to VERBOSITY_VERY_VERBOSE, false otherwise

setDecorated()

Sets the decorated flag.

public setDecorated(mixed $decorated) : mixed
Parameters
$decorated : mixed

Whether to decorate the messages

setVerbosity()

Sets the verbosity of the output.

public setVerbosity(mixed $level) : mixed
Parameters
$level : mixed

The level of verbosity (one of the VERBOSITY constants)

write()

Writes a message to the output.

public write(mixed $messages[, mixed $newline = false ][, mixed $options = self::OUTPUT_NORMAL ]) : mixed
Parameters
$messages : mixed

The message as an iterable of strings or a single string

$newline : mixed = false

Whether to add a newline

$options : mixed = self::OUTPUT_NORMAL

A bitmask of options (one of the OUTPUT or VERBOSITY constants), 0 is considered the same as self::OUTPUT_NORMAL | self::VERBOSITY_NORMAL

writeln()

Writes a message to the output and adds a newline at the end.

public writeln(mixed $messages[, mixed $options = self::OUTPUT_NORMAL ]) : mixed
Parameters
$messages : mixed

The message as an iterable of strings or a single string

$options : mixed = self::OUTPUT_NORMAL

A bitmask of options (one of the OUTPUT or VERBOSITY constants), 0 is considered the same as self::OUTPUT_NORMAL | self::VERBOSITY_NORMAL

doWrite()

Writes a message to the output.

protected doWrite(mixed $message, mixed $newline) : mixed
Parameters
$message : mixed

A message to write to the output

$newline : mixed

Whether to add a newline or not

hasColorSupport()

Returns true if the stream supports colorization.

protected hasColorSupport() : bool

Colorization is disabled if not supported by the stream:

This is tricky on Windows, because Cygwin, Msys2 etc emulate pseudo terminals via named pipes, so we can only check the environment.

Return values
bool —

true if the stream supports colorization, false otherwise
