NAME
    Term::Detect - Detect running under terminal (and get terminal
    information)

VERSION
    version 0.08

SYNOPSIS
     use Term::Detect qw(detect_terminal);
     say "Running under terminal" if detect_terminal();

DESCRIPTION
FUNCTIONS
  detect_terminal([$flag]) => ANY
    Return undef if not detected running under terminal. Otherwise return a
    hash of information about terminal (emulator software, color depth).
    Some information are only returned if requested via $flag, for
    performance reason.

    $flag is a string and can contain one or more characters to
    enable/request extra information. Currently known flags:

    *   p (for parent processes)

    Result:

    *   emulator_engine => STR

    *   emulator_software => STR

        Currently Konsole and xterm can be detected through environment
        because they publish some environment variables.

        If $flag contains "p", will execute "pstree" to try to find out
        emulator software from parent process.

    *   color_depth => INT

        Either 0 (does not support ANSI color codes), 16, 256, or 16777216
        (2**24).

    *   default_bgcolor => STR (6-hexdigit RGB)

        For example, any xterm is assumed to have white background (ffffff)
        by default, while Konsole is assumed to have black (000000).

    *   unicode => BOOL

        Whether terminal supports Unicode/wide characters.

  detect_terminal_cached([$flag]) => ANY
    Just like "detect_terminal()" but will cache the result. Can be used by
    applications or modules to avoid repeating detection process.

TODO
    Better detection of terminal emulator's background color by peeking into
    its configuration.
