function Console::isInteractive

Returns if the file descriptor is an interactive terminal or not.

Normally, we want to use a resource as a parameter, yet sadly it's not always available, eg when running code in interactive console (`php -a`), STDIN/STDOUT/STDERR constants are not defined.

Parameters

int|resource $fileDescriptor:

2 calls to Console::isInteractive()

Console::getNumberOfColumns in vendor/sebastian/environment/src/Console.php

Returns the number of columns of the terminal.

Console::hasColorSupport in vendor/sebastian/environment/src/Console.php

Returns true if STDOUT supports colorization.
