class Athena::Console::Helper::Formatter
inherits Athena::Console::Helper #

Provides additional ways to format output messages than ACON::Formatter::OutputStyle can do alone, such as:

  • Printing messages in a section
  • Printing messages in a block
  • Print truncated messages.

The provided methods return a String which could then be passed to ACON::Output::Interface#print or ACON::Output::Interface#puts.

Methods#

#format_block(messages : String | Enumerable(String), style : String, large : Bool = false)#

Prints the provided messages in a block formatted according to the provided style, with a total width a bit more than the longest line.

The large options adds additional padding, one blank line above and below the messages, and 2 more spaces on the left and right.

output.puts formatter.format_block({"Error!", "Something went wrong"}, "error", true)

#truncate(message : String, length : Int, suffix : String = "...") : String#

message = "This is a very long message, which should be truncated"
truncated_message = formatter.truncate message, 7
output.puts truncated_message # => This is...

If length is negative, it will start truncating from the end.

message = "This is a very long message, which should be truncated"
truncated_message = formatter.truncate message, -4
output.puts truncated_message # => This is a very long message, which should be trunc...
