-- Hoogle documentation, generated by Haddock -- See Hoogle, http://www.haskell.org/hoogle/ -- | Print text to terminal with colors and effects -- -- rainbow helps you print Text chunks to a terminal with colors and -- effects such as bold, underlining, etc. You pair each Text with a -- description of how it should appear. Rainbow works with both 8-color -- and 256-color terminals. -- -- rainbow uses the terminfo package which, in turn, needs the full C -- library for ncurses installed, including the development headers. -- Before installing terminfo, you may need to install the ncurses -- headers (for instance, on Debian systems, install the libncurses5-dev -- package.) @package rainbow @version 0.4.0.0 -- | Handles colors and special effects for text. Internally this module -- uses the Haskell terminfo library, which links against the UNIX -- library of the same name, so it should work with a wide variety of -- UNIX terminals. -- -- The building block of Rainbow is the Chunk. Each Chunk -- comes with a TextSpec, which specifies how the text should look -- on 8-color and on 256-color terminals. The Chunk is a full -- specification; that is, although Chunks are typically printed -- one after the other, the appearance of one Chunk does not -- affect the appearance of the next Chunk. -- -- You have full freedom to specify different attributes and colors for 8 -- and 256 color terminals; for instance, you can have text appear red on -- an 8-color terminal but blue on a 256-color terminal. -- -- A Chunk is a Monoid, so you can combine them using the -- usual monoid functions, including <>. You can create a -- Chunk with text using fromString, but this library is -- much more usable if you enable the OverloadedStrings GHC extension: -- -- 
--   {-# LANGUAGE OverloadedStrings #-}
--
-- -- and all future examples assume you have enabled OverloadedStrings. -- -- Here are some basic examples: -- -- 
--   putChunkLn $ "Some blue text" <> f_blue
--   putChunkLn $ "Blue on red background" <> f_blue <> b_red
--   putChunkLn $ "Blue on red, foreground bold" <> f_blue <> b_red <> bold
--
-- -- But what makes Rainbow a little more interesting is that you can also -- specify output for 256-color terminals. To use these examples, be sure -- your TERM environment variable is set to something that supports 256 -- colors (like xterm-256color) before you start GHCi: -- -- 
--   putChunkLn $ "Blue on 8-color terminal, red on 256-color terminal"
--              <> c8_f_blue <> c256_f_red
--
-- -- If mappend multiple chunks that change the same property, the -- rightmost one "wins": -- -- 
--   putChunkLn $ "This will be blue" <> f_red <> f_blue
--
-- -- This property comes in handy if you want to specify a default color -- for 8- and 256-color terminals, then a more specific shade for a -- 256-color terminal: -- -- 
--   putChunkLn $ "Pink" <> f_red <> c256_f_201
--
-- -- However, if you use mappend to add additional Chunks -- that have text, the text will be appended: -- -- 
--   putChunkLn $ f_green <> "You will see this text "
--                <> "and this text too, but it will all be blue"
--                <> f_blue
--
-- -- Although one chunk can have different colors on 8- and 256-color -- terminals, it cannot have different colors on the same terminal. That -- is, if you want to print some text in one color and some text in -- another color, make two chunks. module System.Console.Rainbow -- | Which terminal definition to use. data Term -- | Using this terminal should always succeed.

What actually happens when you use Bold is going to depend on -- your terminal. For example, xterm allows you actually use a bold font -- for bold, if you have one. Otherwise, it might simulate bold by using -- overstriking. Another possibility is that your terminal might use a -- different color to indicate bold. For more details (at least for -- xterm), look at xterm (1) and search for boldColors. -- -- If your terminal uses a different color for bold, this allows an -- 8-color terminal to really have 16
