6+ * Fixed a build issue with a test program.
12+ * Add support for 24-bit color (thanks @u-quark). This change
13+ updates Vty to look at the `COLORTERM` environment variable that is
14+ conventionally used to advertise support for truecolor escape
15+ sequences. The change also updates the Vty demo to demonstrate
16+ 24-bit colors. This change also adds a new data type, `ColorMode`,
17+ to represent the color mode in use, as well as an `Output` interface
18+ field, `outputColorMode`, to track the active color mode and use it
19+ to clamp emitted color escape sequences to the active color range.
22+ * All types in `Graphics.Vty.Input.Events` now have strict constructor
24+ * Internal events are now wrapped in a new `InternalEvent` type to
25+ improve how signal handling is done. This change modifies the `Input`
26+ type's event channel API to produce `InternalEvents`, not `Events`.
27+ The new `InternalEvent` either wraps `Event` with the `InputEvent`
28+ constructor (the previous behavior) or indicates that Vty resumed
29+ after handling a signal using the `ResumeAfterSignal` constructor.
30+ This change avoids the previous use of `EvResize` with lazy exception
31+ arguments as a sentinel value for `ResumeAfterSignal`.
34+ * Bracketed paste parsing performance has been greatly improved thanks
35+ to benchmarking and optimization work by @iphydf. As part of that
36+ work, Vty now uses bytestrings rather than Strings internally when
37+ parsing input to look for events.
38+ * The `\b` value is now interpreted as `KBS` (thanks @vglfr)
44+ * Added an `NFData` instance for `Event` (thanks Mario Lang)
45+ * Removed `Monoid` and `Semigroup` instances for `Attr` and
46+ `MaybeDefault`. This change removed the instances because they were
47+ misbehaved; merging `Attr` and `MaybeDefault` values with these
48+ instances resulted in field value losses. For example, before this
51+(defAttr `withForeColor` blue) <> (defAttr `withBackColor` green)
55+ (defAttr `withBackColor` green)
57+ because the instances were designed to favor the right-hand
58+ arguments' fields even if they had not been explicitly set
59+ (a consequence of the `MaybeDefault` `Semigroup` instance).
60+ While that behavior was sensible specifically in the context of
61+ `Graphics.Vty.Inline`, it wasn't a useful user-facing API and it made
62+ for surprising instance behavior. Since there is actually no good way
63+ to handle this in a `Semigroup` instance for `Attr` -- some choices
64+ have to be made about how to merge two attributes' foreground colors,
65+ and that won't be much better than what we had -- the instance was
73+* The `Cursor` type got a new `PositionOnly` constructor for cursor
74+ placement without visibility.

91+ check for feature support in terminfo
94+ * Detect utf-8 mode in `LANG` regardless of case (thanks Emeka
100+New features and API changes:
101+ * Added support for strikethrough mode. This change adds a new
102+ `strikethrough` `Style` value and uses the `smxx` and `rmxx`
103+ Terminfo capabilities to activate and deactivate strikethrough mode,
104+ respectively. If the terminfo does not report those capabilities,
105+ this style is ignored.
106+ * `Output`: added the `setDisplayBounds` field to set the output
107+ dimensions of the output handle; added an implementation of this for
108+ the `TerminfoBased` backend.
111+ * The C prototype for `vty_c_get_window_size` in `gwinsz.h` was fixed.
117+ * Added `Graphics.Vty.setWindowTitle` to emit an escape
118+ sequence to set the window title, provide the terminal emulator
119+ accepts Xterm-style title sequences. For details, see:
120+ https://tldp.org/HOWTO/Xterm-Title-3.html
126+ * The Input type got a new field, 'restoreInputState'. This field
127+ allows the end user to have direct access to the logic needed to
128+ restore the terminal's input state flags. Prior to having this field,
129+ this state restoration logic could only be invoked as part of calling
130+ 'shutdownInput', but since that function does other things (like
131+ killing threads) it is not advisable to call it repeatedly (which is
132+ necessary in the use case this change is intended to support). This
133+ can be called directly to restore the input state flags as needed,
134+ although this is not required if 'shutdown' (or 'shutdownInput') is
138+ * attributeControl: explicitly enable the ICRNL terminal mode flag (see

152+ * `installUnicodeWidthTable`: use `throwIO`, not `throw`
157+This release improves Vty's support for multi-column Unicode characters
158+and provides greater compatibility with a wider array of terminal
159+emulators. The following sections summarize the relevant changes, but an
160+overview of the new functionality is motivated and detailed in the new
161+"Multi-Column Character Support" README section. For
162+historical context, please also consider reading over
163+[#175](https://github.com/jtdaugherty/vty/issues/175).
166+ * New modules were added:
167+ * `Graphics.Vty.UnicodeWidthTable.Types`
168+ * `Graphics.Vty.UnicodeWidthTable.IO`
169+ * `Graphics.Vty.UnicodeWidthTable.Query`
170+ * `Graphics.Vty.UnicodeWidthTable.Install`
171+ * The `Config` type got a new field, `allowCustomUnicodeWidthTables`,
172+ that controls whether `mkVty` will attempt to load a Unicode width
173+ table if specified in the configuration.
175+Configuration file changes:
176+ * A new syntax was added to support specifying Unicode width tables on
177+ a per-`TERM` basis. The syntax is `widthMap <TERM> <PATH>`. See the
178+ documentation for `Graphics.Vty.Config` for details. Since prior
179+ versions of this library will silently ignore any configuration file
180+ lines they cannot parse, this change to user configuration files is
181+ at least non-breaking for older versions of Vty.
184+ * The `mkVty` function now automatically attempts to load a custom
185+ Unicode width table if one is specified in the configuration,
186+ provided `allowCustomUnicodeWidthTables` is not set to `Just False`.
187+ See the documentation for `Graphics.Vty.mkVty` for details.
188+ * Vty now includes a command line tool, `vty-build-width-table`, that
189+ queries the terminal emulator to construct a custom Unicode width
190+ table and optionally update the Vty configuration file to use it.
191+ Programs that want to use that tool's functionality may also do so
192+ via the API exposed in the various modules listed above.
197+* Added `Graphics.Vty.Config.getTtyEraseChar` to support querying the
198+ kernel for the current terminal's settings to obtain the character
199+ assigned by the `stty erase` command. That can then be added to the
200+ Vty configuration's input map to map to `KBS` (backspace) if desired.
205+* Resolved various import warnings (thanks @glguy)
206+* Removed the `MonadIO` constraint from the Output type's fields and
207+ removed `MonadFail` uses (PR #177, thanks @glguy)
208+* Clarified documentation for ANSI colors (thanks Colby Jenn)
209+* `Graphics.Vty.Attributes` no longer re-exports
210+ `Graphics.Vty.Attributes.Color`

213+* Raised upper bound for `microlens` to 0.4.12 (thanks Artyom Kazak)
214+* Changed from using `System.Posix.Env.getEnv` to

216+* Added `Graphics.Vty.Image` functions for dealing with character width
217+ computations on `Text` values instead of `Strings`:
226+* Avoided a conflict with a Microlens 0.4.10 operator and added an
227+ upper bound on Microlens of 0.4.11.

233+ Vty handle has had its 'shutdown' function called (thanks Ian
235+* Vty's shutdown function is now thread-safe.

245+* Add Generic and NFData instances for some types

248+* Updated Travis build settings (thanks Eric Mertens)
253+* Fixed a bug where italics did not combine properly with other display
254+ modes (#155, thanks Eric Mertens)
259+* Added support for italicized output when terminfo supports it. This
260+ takes the form of a new Style, "italic". Note that most terminfo
261+ descriptors do not report capabilities for italics, so support for
262+ this will be very spotty.

264+ are not permitted in their inputs.
