NAME

Mojo::Log::Colored - Colored Mojo logging

SYNOPSIS

    use Mojo::Log::Colored;
    # Log to STDERR
    $app->log(
        Mojo::Log::Colored->new(
            
            # optionally set the colors
            colors => {
                debug => "bold bright_white",
                info  => "bold bright_blue",
                warn  => "bold green",
                error => "bold yellow",
                fatal => "bold yellow on_red",
            }
        )
    );

DESCRIPTION

Mojo::Log::Colored is a logger for Mojolicious with colored output for the terminal. It lets you define colors for each log level based on Term::ANSIColor and comes with sensible default colors. The full lines in the log will be colored.

Since this inherits from Mojo::Log you can still give it a "file", but the output would also be colored. That does not make a lot of sense, so you don't want to do that. Use this for development, not production.

ATTRIBUTES

Mojo::Log::Colored implements the following attributes.

colors

    my $colors = $log->colors;
    $log->colors(
        {
            debug => "bold bright_white",
            info  => "bold bright_blue",
            warn  => "bold green",
            error => "bold yellow",
            fatal => "bold yellow on_red",
        }
    );

Takes a hash reference with the five log levels as keys and strings of colors as values. Refer to Term::ANSIColor for more information about what kind of color you can use.

You can turn off coloring for specific levels by omitting them from the config hash.

    $log->colors(
        {
            fatal => "bold green on_red",
        }
    );

The above will only color fatal messages. All other levels will be in your default terminal color.

format

    my $cb = $log->format;
    $log   = $log->format( sub { ... } );

A callback for formatting log messages. Cannot be passed to "new" at construction! See Mojo::Log for more information.

METHODS

Mojo::Log::Colored inherits all methods from Mojo::Log and does not implement new ones.

BREAKING CHANGES

Mojolicious changed the way multi-line log messages are emitted in version 9 <https://mojolicious.io/blog/2021/02/14/announcing-mojolicious-9-0/>. This logger honours this default format.

ACKNOWLEDGEMENTS

This plugin was inspired by lanti asking about a way to find specific errors more easily in the Mojo log during unit test runs on Stack Overflow <https://stackoverflow.com/q/44965998/1331451>.
