Changes

Version 1.1.3

• Module System.Console.ANSI.Codes spun out to dependency package ansi-terminal-types-1.1.3.

Version 1.1.2

• Add enableLineWrap and disableLineWrap, and support for enabling and disabling automatic line wrapping.

Version 1.1.1

• Use of C function setenv() in one thread can cause other threads calling C functions that query environment variables to crash. On Unix-like operating systems, where such functions are used, the implementations of hSupportsANSI and hSupportsANSIColor now avoid unnecessary calls of System.Environment.lookupEnv.

• Improvements to Haddock documentation.

Version 1.1

• Add support for console layer Underlining and underlining styles CurlyUnderline, DottedUnderline and DashedUnderline.
• Add type synonyms Parameter, SubParam, and ParamWithSubs to represent SGR parameter values with and without following parameter substrings comprised of one or more parameter elements (including empty elements).
• Add csi' and sgrToCode', corresponding to csi and sgrToCode but capable of handling a parameter value followed by a parameter substring.

Version 1.0.2

• On Windows, fix linker error about a duplicate symbol castUINTPtrToPtr.

Version 1.0.1

• On Windows, the processing of 'ANSI' control characters in output is enabled by default in Windows Terminal but is not enabled by default in ConHost terminals. Additions have been made to allow support of users of ConHost terminals.
• Add hNowSupportsANSI. On Unix, the function is equivalent to hSupportsANSI. On Windows, in Windows Terminal and ConHost terminals, the action can try to enable the processing of 'ANSI' control characters in output.
• In Windows Terminal and ConHost terminals, hSupportsANSI will yield False if the processing of 'ANSI' control characters in output is not enabled.
• Deprecated hSupportsANSIWithoutEmulation is now consistent with hNowSupportsANSI.
• Improvements to Haddock documentation. Version 1.0

---

• On Windows, drop support for legacy Windows requiring emulation. The package assumes Windows Terminal has replaced ConHost terminals on supported versions of Windows. Functions that yield actions no longer enable (re-enable) the processing of 'ANSI' control characters in output.
• On Windows, the package no longer depends (directly or indirectly) on the Win32, array,containers, deepseq, filepath, ghc-boot-th, mintty, pretty or template-haskell packages.
• hSupportsANSI no longer assumes that the given handle is writeable.
• hSupportsANSIWithoutEmulation is deprecated.

Version 0.11.5

• Module System.Console.ANSI.Types spun out to new dependency package ansi-terminal-types-0.11.5.
• Drop support for GHC versions before GHC 7.10.1 (released March 2015).
• Improvements to Haddock documentation.

Version 0.11.4

• Add reportLayerColor, getReportedLayerColor and getLayerColor for querying the layer color on terminals that support the functionality.
• Add useAlternateScreenBuffer and useNormalScreenBuffer, and support for switching between the Alternate and Normal Screen Buffers.
• When the argument is 0, cursorUpCode, cursorDownCode, cursorForwardCode, cursorBackwardCode,scrollPageUpCode and scrollPageDownCode now yield "", and cursorUpLineCode and cursorDownLineCode now yield the equivalent of setCursorColumnCode 0. This is because, on some terminals, a 0 parameter for the underlying 'ANSI' code specifies a default parameter of 1.
• Add osc as a utility function, for OSC sequences.
• setTitle now uses the recommended STRING TERMINATOR (ST) of \ESC\\, rather than the legacy \BEL (\007), and filters the title of all non-printable characters, not just \BEL.
• Improvements to Haddock documentation.

Version 0.11.3

• Add hyperlink, hyperlinkWithId and hyperlinkWithParams, and support for clickable hyperlinks.

Version 0.11.2

• On Windows, fix compatability with the Windows I/O Manager (WinIO) when GHC >= 9.0.1 but Win32 < 2.9.0.0.
• Improvements to Haddock documentation.

Version 0.11.1

• On Windows, fix compatability with the Windows I/O Manager (WinIO) introduced in GHC 9.0.1, by incorporating changes made in package Win32-2.13.2.0 in that regard.
• Improvements to Haddock documentation.

Version 0.11

• Remove deprecated getCursorPosition0. (Use getCursorPosition instead.)
• On Unix-like operating systems, the temporary turning off of echoing is moved from getReportedCursorPosition to hGetCursorPositon.
• On Unix-like operating systems, fix a bug in getCursorPosition and hGetCursorPosition, where the console input stream was was not always clear before the cursor position was emitted into it.

Version 0.10.3

• Add getCursorPosition as a synonym of getCursorPosition0 and deprecate the latter.

Version 0.10.2

• hGetTerminalSize now assumes a terminal is no bigger than 9,999 by 9,999 (previously, no bigger than 999 by 999).
• On Windows, fix a bug where emulated cursor movement functions differed from Windows 10 (movement bounded by the current viewport).

Version 0.10.1

• Add hGetCursorPosition and hGetTerminalSize.
• On Unix-like operating systems, fix a bug where getReportedCursorPosition could block indefinitely if no information was forthcoming on the console input stream.
• Improvements to Haddock documentation.

Version 0.10

• Add support for setting the default color with new SetDefaultColor constructor of the SGR type.
• getTerminalSize now flushes the stdout channel, to ensure the cursor position is unaffected.

Version 0.9.1

• Flag modules with GHC's 'Safe Haskell' language extensions (from GHC 7.2.1).
• Improvements and corrections to Haddock documentation.

Version 0.9

• Add support for 256-color palettes with new SetPaletteColor constructor of the SGR type, and xterm6LevelRGB, xterm24LevelGray and xtermSystem.
• Remove deprecated getCursorPosition. (Use getCursorPosition0 instead.)
• Add hSupportsANSIColor.
• Add getTerminalSize.
• Improvements to Haddock documentation.

Version 0.8.2

• Add getCursorPosition0 and deprecate getCursorPosition. Any position provided by the latter is 1-based. Any position provided by the former is 0-based, consistent with setCursorColumn and setCursorPosition.
• Improvements to Haddock documentation in respect of 0-based and 1-based cursor positions.

Version 0.8.1

• Add hSupportsANSIWithoutEmulation. On Windows 10, if the handle is identified as connected to a native terminal ('Command Prompt' or 'PowerShell'), the processing of 'ANSI' control characters will be enabled.

Version 0.8.0.4

• On Windows, hSupportsANSI now recognises if the handle is connected to a 'mintty' terminal.
• Drop support for GHC versions before GHC 7.0.1 (released November 2010)

Version 0.8.0.3

• On Windows, try to enable ANSI on ConHost terminals even if a TERM environment variable exits (such as with the Hyper 2 terminal)
• Minor improvements to Haddock documentation

Version 0.8.0.2

• Improve README and Haddock documentation
• On Windows, fix compatability with earlier GHC versions
• Drop support for GHC versions before 6.12.1 (released December 2009)

Version 0.8.0.1

• On Windows, if the standard output channel is valid but not a ConHost terminal, assume it is ANSI-enabled rather than failing
• On Windows, output the improved error message to the standard error channel rather than the standard output channel

Version 0.8

• Make the fields of SGR strict
• Make compatible with GHC 8.2.2
• Improve the error message on Windows when not ANSI-capable or ConHost
• Recognise Appveyor build environment as ANSI-enabled

Version 0.7.1.1

• Fix a couple of issues with the Reset emulation on Windows

Version 0.6.1

• BoldIntensity no longer changes background color on Windows
• setSGR [] was not equivalent to setSGR [Reset] on Windows, even though it should be according to the documentation. This is now fixed.
