module Athena::Console::Formatter::OutputStyleInterface
#
Output styles represent reusable formatting information that can be used when formatting output messages.
Athena::Console
comes bundled with a few common styles including:
- error
- info
- comment
- question
Whenever you output text via an ACON::Output::Interface
, you can surround the text with tags to color its output. For example:
# Green text
output.puts "<info>foo</info>"
# Yellow text
output.puts "<comment>foo</comment>"
# Black text on a cyan background
output.puts "<question>foo</question>"
# White text on a red background
output.puts "<error>foo</error>"
Custom Styles#
Custom styles can also be defined/used:
my_style = ACON::Formatter::OutputStyle.new :red, "#f87b05", Colorize::Mode[:bold, :underline]
output.formatter.set_style "fire", my_style
output.puts "<fire>foo</>"
Global Custom Styles#
You can also make your style global by extending ACON::Application
and adding it within the #configure_io
method:
class MyCustomApplication < ACON::Application
protected def configure_io(input : ACON::Input::Interface, output : ACON::Output::Interface) : Nil
super
my_style = ACON::Formatter::OutputStyle.new :red, "#f87b05", Colorize::Mode[:bold, :underline]
output.formatter.set_style "fire", my_style
end
end
Inline Styles#
Styles can also be defined inline when printing a message:
# Using named colors
output.puts "<fg=green>foo</>"
# Using hexadecimal colors
output.puts "<fg=#c0392b>foo</>"
# Black text on a cyan background
output.puts "<fg=black;bg=cyan>foo</>"
# Bold text on a yellow background
output.puts "<bg=yellow;options=bold>foo</>"
# Bold text with underline.
output.puts "<options=bold,underline>foo</>"
Clickable Links#
Commands can use the special href
tag to display links within the console.
output.puts "<href=https://athenaframework.org>Athena</>"
If your terminal supports it, you would be able to click the text and have it open in your default browser. Otherwise, you will see it as regular text.
