Description
This module exports functions that return String values containing codes
in accordance with: (1) standard ECMA-48 Control Functions for Coded
Character Sets (5th edition, 1991); or (2) in the case of saveCursorCode,
restoreCursorCode, reportCursorPositionCode and setTitleCode, the XTerm
control sequence.
The reference used for the codes in this module was http://en.wikipedia.org/wiki/ANSI_escape_sequences.
The module System.Console.ANSI exports functions with the same names as those in this module. On some versions of Windows, the terminal in use may not be ANSI-capable. When that is the case, the same-named functions exported by module System.Console.ANSI return "", for the reasons set out in the documentation of that module.
Consequently, if module System.Console.ANSI is also imported, this module is intended to be imported qualified, to avoid name clashes with those functions. For example:
import qualified System.Console.ANSI.Codes as ANSI
- module System.Console.ANSI.Types
- cursorUpCode :: Int -> String
- cursorDownCode :: Int -> String
- cursorForwardCode :: Int -> String
- cursorBackwardCode :: Int -> String
- cursorUpLineCode :: Int -> String
- cursorDownLineCode :: Int -> String
- setCursorColumnCode :: Int -> String
- setCursorPositionCode :: Int -> Int -> String
- saveCursorCode :: String
- restoreCursorCode :: String
- reportCursorPositionCode :: String
- clearFromCursorToScreenEndCode :: String
- clearFromCursorToScreenBeginningCode :: String
- clearScreenCode :: String
- clearFromCursorToLineEndCode :: String
- clearFromCursorToLineBeginningCode :: String
- clearLineCode :: String
- scrollPageUpCode :: Int -> String
- scrollPageDownCode :: Int -> String
- setSGRCode :: [SGR] -> String
- hideCursorCode :: String
- showCursorCode :: String
- setTitleCode :: String -> String
- colorToCode :: Color -> Int
- csi :: [Int] -> String -> String
- sgrToCode :: SGR -> [Int]

Changing the title
Thanks to Brandon S. Allbery and Curt Sampson for pointing me in the right direction on xterm title setting on haskell-cafe. The "0" signifies that both the title and "icon" text should be set: i.e. the text for the window in the Start bar (or similar) as well as that in the actual window title. This is chosen for consistent behaviour between Unixes and Windows.
XTerm control sequence to set the Icon Name and Window Title.
Utilities
colorToCode :: Color -> Int Source #
colorToCode color returns the 0-based index of the color (one of the
eight colors in the standard).
