enum Athena::Console::Output::Verbosity #

Verbosity levels determine which messages will be displayed, essentially the same idea as Log::Severity but for console output.

For example:

# Output nothing
./console my-command -q
./console my-command --quiet

# Display only useful output
./console my-command

# Increase the verbosity of messages
./console my-command -v

# Also display non-essential information
./console my-command -vv

# Display all messages, such as for debugging
./console my-command -vvv

As used in the previous example, the verbosity can be controlled on a command invocation basis using a CLI option, but may also be globally set via the SHELL_VERBOSITY environmental variable.

When you output a message via ACON::Output::Interface#puts or ACON::Output::Interface#print, they also provide a way to set the verbosity at which that message should print:

protected def execute(input : ACON::Input::Interface, output : ACON::Output::Interface) : ACON::Command::Status
  # Via conditional logic
  if output.verbosity.verbose?
    output.puts "Obj class: #{obj.class}"
  end

  # Inline within the method
  output.puts "Only print this in verbose mode or higher", verbosity: :verbose

  ACON::Command::Status::SUCCESS
end

Tip

The full stack trace of an exception is printed in ACON::Output::Verbosity::VERBOSE mode or higher.

Members#

QUIET = -1 #

Silences all output. Equivalent to -q, --quiet CLI options or SHELL_VERBOSITY=-1.

NORMAL = 0 #

Normal behavior, display only useful messages. Equivalent not providing any CLI options or SHELL_VERBOSITY=0.

VERBOSE = 1 #

Increase the verbosity of messages. Equivalent to -v, --verbose=1 CLI options or SHELL_VERBOSITY=1.

VERY_VERBOSE = 2 #

Display all the informative non-essential messages. Equivalent to -vv, --verbose=2 CLI options or SHELL_VERBOSITY=2.

DEBUG = 3 #

Display all messages, such as for debugging. Equivalent to -vvv, --verbose=3 CLI options or SHELL_VERBOSITY=3.
