 2025-06-22 Version 1.0.5
 
 	Manual:
 	* fix: "User-friendly documentation for alternate screen"
 	  https://bugs.freebsd.org/285459.
 	  Improve bsddialog.1: --alternate-screen and --normal-screen.
 
 	NetBSD (tested on amd64) refactoring, no function changes:
 	* https://gitlab.com/alfix/bsddialog/-/merge_requests/4
 	  lib: include <stdarg.h> in lib_util.c.
 	* https://gitlab.com/alfix/bsddialog/-/merge_requests/5
 	  a call to curses' refresh() is performed, while a local
 	  variable is also called refresh.
 	* Makefiles: add install and uninstall targets (both GND and BSD)
 	  https://gitlab.com/alfix/bsddialog/-/merge_requests/3
 
 	MacOS (tested on amd64) refactoring, no function changes:
 	* https://gitlab.com/alfix/bsddialog/-/merge_requests/6
 	  utility: replace u_int with unsigned int.
 
 	Library:
 	* fix: useless refreshes, https://gitlab.com/alfix/bsddialog/-/issues/8:
 	  "It takes lot of time when running over a 115200 UART".
 	  Not fixed for bsddialog_gauge() because it has to be rewritten.
 	* change: bsddialog_backtitle() does not update the screen so the
 	  backtitle is not printed. To use if a dialog is built later.
 	  Rationale: see "115200 UART" problem above.
 	* add: bsddialog_backtitle_rf() to print a top title refreshing the
 	  screen like bsddialog_backtitle() was previously.
 	* change: forms, ENTER is also a navigation keys in forms fields.
 	  Request: https://bugs.freebsd.org/287592
 	  If conf.button.always_active is true the form is closes immediatly.
 
 	Library and implicitly utility:
 	* fix: textbox buttons returned values (was always OK).
 	  Thanks to https://reviews.freebsd.org/D48668.
 	* change: TAB is a navigation keys in forms. Previously it directly
 	  switched form-fields <-> buttons.
 	  Request: https://bugs.freebsd.org/287592
 
 	Utility:
 	* change: forms, ENTER is a also navigation keys in forms fields.
 	  Previously it directly closed the form except with --switch-buttons
 	  Request: https://bugs.freebsd.org/287592
 
 
 2024-07-01 Version 1.0.4
 
 	Utility internal refactoring (no functional change):

 	    Reported and fixed by Kyle Evans.
 
 2024-05-27 Version 1.0.3
 
 	Utility:
 	change: --form and --mixedform do not print field value to output fd if
 	        <fieldlen> is <= 0 (readonly). To note --mixedgauge continues
 	        to print field value if <flag> = 2 (readonly) unless <fieldlen>
 	        is <= 0 (as described previously).
 
 
 2024-04-11 Version 1.0.2
 
 	Utility:
 	improvements and changes for --form and --mixedform:
 	    * add: <maxletters> 0 sets <maxletters> like <fieldlen>.
 	    * add: <fieldlen> 0 sets <fieldlen> like <init> width and readonly.
 	    * change: <maxletters> 0 was an error (remains error in lib).
 	    * change: <fieldlen> 0 was an error (remains error in lib)
 	      (<fieldlen> 0 and <init> "" is still an error.).
 
 	Library and implicitly utility:
 	* add: Ctrl-l to redraw dialog.
 	    Request stable@freebsd.org January 2024.
 	* add: -, +, Ctrl-p, Ctrl-n for several dialogs.

 	    Ctrl-p, Ctrl-n for menu, request hackers@freebsd.org February 2024.
 	* fix: escaped text ending with an escape symbol.
 	* change: truncate mixedgauge long (over the screen/minibars)
 	    minilabels adding "...". As a result, avoid check-size error.
 	    https://gitlab.com/alfix/bsddialog/-/issues/6.
 	* change: invert UP/DOWN keys to set a rangebox value.

-# BSDDialog 1.0.5
+# BSDDialog 1.1
 
 This project provides **bsddialog** and **libbsddialog**, an utility
 and a library to build scripts and tools with TUI dialogs and widgets.
 
 
 ## Demo
 
 [Screenshots](https://www.flickr.com/photos/alfonsosiciliano/albums/72157720215006074).
 
 
 ## Getting Started
 
 FreeBSD and Linux:
 
 ```
 % git clone https://gitlab.com/alfix/bsddialog.git
 % cd bsddialog
 % make
 % ./bsddialog --msgbox "Hello World!" 8 20
 ```
 
 Output:
 
 ![screenshot](screenshot.png)
 
 
 ## Utility
 
 **Dialogs:**
 
 --calendar, --checklist, --datebox, --form, --gauge, --infobox, --inputbox,
 --menu, --mixedform, --mixedgauge, --msgbox, --passwordbox, --passwordform,
---pause, --radiolist, --rangebox, --textbox, --timebox, --treeview, --yesno.
+--pause, --radiolist, --rangebox, --slider, --textbox, --timebox, --treeview,
+--yesno.
 
 **Manual**
 
  - [bsddialog(1)](https://alfonsosiciliano.gitlab.io/posts/2022-01-26-manual-bsddialog.html)
 
 
 **Examples**:
 
 ```
 % ./bsddialog --backtitle "TITLE" --title msgbox --msgbox "Hello World!" 5 30
 % ./bsddialog --theme blackwhite --title msgbox --msgbox "Hello World!" 5 30
 % ./bsddialog --begin-y 2 --default-no --title yesno --yesno "Hello World!" 5 30
 % ./bsddialog --ascii-lines --pause "Hello World!" 8 50 10
 % ./bsddialog --checklist "Space to select" 0 0 0 Name1 Desc1 off Name2 Desc2 on
 % ./bsddialog --title yesno --hline "bsddialog" --yesno "Hello World!" 5 25
 % ./bsddialog --extra-button --help-button --yesno "Hello World!" 0 0
 ```
 
 and [Examples](https://gitlab.com/alfix/bsddialog/-/tree/main/examples_utility)
 in the _Public Domain_ to build new projects:
 ```
 % sh ./examples_utility/calendar.sh
 % sh ./examples_utility/checklist.sh
 % sh ./examples_utility/datebox.sh
 % sh ./examples_utility/form.sh
 % sh ./examples_utility/gauge.sh
 % sh ./examples_utility/infobox.sh

 % sh ./examples_utility/yesno.sh
 ```
 
 ## Library
 
 **API**
 
  - [bsddialog.h](https://gitlab.com/alfix/bsddialog/-/blob/main/lib/bsddialog.h)
  - [bsddialog\_theme.h](https://gitlab.com/alfix/bsddialog/-/blob/main/lib/bsddialog_theme.h)
 
 
 **Manual**
 
  - [bsddialog(3)](https://alfonsosiciliano.gitlab.io/posts/2022-01-15-manual-libbsddialog.html)
 
 
 **Examples**:
 
 [Examples](https://gitlab.com/alfix/bsddialog/-/tree/main/examples_library)
 in the _Public Domain_ to build new projects:
 ```
 % cd examples_library
 % sh compile
 % ./calendar
 % ./checklist
 % ./datebox
 % ./form
 % ./gauge
 % ./infobox
 % ./menu
 % ./mixedgauge
 % ./mixedlist
 % ./msgbox
 % ./pause
 % ./radiolist
 % ./rangebox
+% ./slider
 % ./theme
 % ./timebox
 % ./yesno
 ```
 
 
 ## TODO and Ideas
 
  - menubar feature.
  - key callback.
  - Right-To-Left text.
  - some terminal does not hide the cursor, move it bottom-right before to getch.
  - refactor backtitle: add WINDOW \*dialog.backtitle for multiline and fix expanding screen.
  - refactor bottomdesc: add WINDOW \*dialog.bottomdesc to fix expandig screen.
  - accessibility https://wiki.freebsd.org/Accessibility/Wishlist/Base.
  - add bool conf.menu.depthlines.
  - implement custom getopt\_long().
  - refactor/redesign gauge().
  - improve grey lines expanding terminal (maybe redrawwin() in hide\_dialog()).
  - more restrictive strtol() and strtoul().
  - implement global buttons handler.
  - doc: external tutorial, theming guide.
  - implement menutype.min\_on.
  - add debug API: bsddialog\_debug(y,x,refresh,"fmt",...).
  - add mouse support.
  - use alarm(2) for bsddialog\_pause.
  - delete form fieldlen constraint, hide or truncate long field in little screens.
  - improve --inputbox autosizing, consider also input length.
  - fix --form "" 0 0 0 Label 1 0 Init 1 12 0 0 (with 0 editable field).
  - fix --mixedform "" 0 0 0 Label 1 0 Init 1 12 0 0 2 (with 0 editable field).
  - add *text* customization to --hmsg *help-message*
  - check --passwordform *fieldlen* like --form and --mixedform.
  - add manuals to Makefiles installe and uninstall targets.
