-6.1.9 (2025-05-07)
-------------
-
-### Build
-If all goes well (pending), ftxui should appear in the Bazel central repository.
-It can be imported into your project using the following lines:
-
-**MODULE.bazel**
-```bazel
-bazel_dep(name = "ftxui", version = "6.1.9")
-```
-
-Thanks @robinlinden and @kcc for the reviews.
-
-### dom
-- Bugfix: Restore the `dbox` behavior from ftxui 5.0.0. To apply bgcolor
-  blending between the two layers, a new `dboxBlend` will be added.
-
-6.1.8 (2025-05-01)
-------------------
-
-### Build
-- Feature: Support `bazel` build system. See #1032.
-  Proposed by Kostya Serebryany @kcc

-  **BUILD.bazel**
-  ```bazel
-  deps = [
-    // Depend on the whole library:
-    "@ftxui//:ftxui",
-
-    // Choose a specific submodule:
-    "@ftxui//:component",
-    "@ftxui//:dom",
-    "@ftxui//:screen",
-  ]
-  ```
-

-  auto italic_text = text("Italic text") | italic;
-  ```
-  ```cpp
-  auto italic_text = italic(text("Italic text"));
-  ```
-  Proposed by @kenReneris in #1009.
-- Feature: Add `hscroll_indicator`. It display an horizontal indicator
-  reflecting the current scroll position. Proposed by @ibrahimnasson in
-  [issue 752](https://github.com/ArthurSonzogni/FTXUI/issues/752)
-- Feature: Add `extend_beyond_screen` option to `Dimension::Fit(..)`, allowing
-  the element to be larger than the screen. Proposed by @LordWhiro. See #572 and
-  #949.
-- Feature: Add support for Selection. Thanks @clement-roblot. See #926.
-  - See `selectionColor` decorator.
-  - See `selectionBackgroundColor` decorator.
-  - See `selectionForegroundColor` decorator.
-  - See `selectionStyle(style)` decorator.
-  - See `selectionStyleReset` decorator.
-- Breaking change: Change how "focus"/"select" are handled. This fixes the
-  behavior.
-- Breaking change: `Component::OnRender()` becomes the method to override to
-  render a component. This replaces `Component::Render()` that is still in use
-  to call the rendering method on the children. This change allows to fix a
-  couple of issues around focus handling.
-
-### Screen
-- Feature: Add `Box::IsEmpty()`.
-- Feature: Color transparency
-    - Add `Color::RGBA(r,g,b,a)`.
-    - Add `Color::HSVA(r,g,b,a)`.
-    - Add `Color::Blend(Color)`.
-    - Add `Color::IsOpaque()`
-
-### Util
-- Feature: Support arbitrary `Adapter` for `ConstStringListRef`. See #843.
-
-### Build
-- Support for cmake's "unity/jumbo" builds. Fixed by @ClausKlein.
-
-5.0.0
------
-
-### Component
-- Breaking: MenuDirection enum is renamed Direction
-- Breaking: GaugeDirection enum is renamed Direction
-- Breaking: Direction enum is renamed WidthOrHeight
-- Breaking: Remove `ComponentBase` copy constructor/assignment.
-- Breaking: MenuOption::entries is renamed MenuOption::entries_option.
-- Breaking: `Ref<{Component}Option>` becomes `{Component}Option` in component constructors.
-- Feature: `ResizeableSplit` now support arbitrary element as a separator.
-- Feature: `input` is now supporting multiple lines.
-- Feature: `input` style is now customizeable.
-- Bugfix: Support F1-F5 from OS terminal.
-- Feature: Add struct based constructor:
-  ```cpp
-  Component Button(ButtonOption options);
-  Component Checkbox(CheckboxOption options);
-  Component Input(InputOption options);
-  Component Menu(MenuOption options);
-  Component MenuEntry(MenuEntryOption options);
-  Component Radiobox(RadioboxOption options);
-  Component Slider(SliderOption<T> options);
-  Component ResizableSplit(ResizableSplitOption options);
-  ```
-- Feature: Add `ScreenInteractive::TrackMouse(false)` disable mouse support.
-
-### Dom
-- Feature: Add `hyperlink` decorator. For instance:
-  ```cpp
-  auto link = text("Click here") | hyperlink("https://github.com/FTXUI")
-  ```
-  See the [OSC 8 page](https://gist.github.com/egmontkob/eb114294efbcd5adb1944c9f3cb5feda).
-  FTXUI support proposed by @aaleino in [#662](https://github.com/ArthurSonzogni/FTXUI/issues/662).
-
-### Screen
-- Breaking: `WordBreakProperty` becomes a uint8_t enum. This yields a 0.8%
-  performance improvement.
-- Breaking: Remove user defined Pixel constructor and equality operator.
-- Performance: 19% faster on benchmarks.
-
-
-### Build
-- Check version compatibility when using cmake find_package()
-- Add `FTXUI_DEV_WARNING` options to turn on warnings when building FTXUI
-- Turn OFF by default `FTXUI_BUILD_DOCS`
-- Turn OFF by default `FTXUI_BUILD_EXAMPLE`

-@page cpp20-modules C++20 Modules
-
-
-> [!WARNING]
-> This feature is still in development, and the API may change in future releases.
-> Your contribution is needed to help us improve the compatibility and usability
-> of C++20 modules in FTXUI. If you encounter any issues or have suggestions,
-> please open an issue.
-
-FTXUI experimentally supports
-[C++20 modules](https://en.cppreference.com/w/cpp/language/modules) to reduce
-compilation times and improve code organization. Each header has a
-corresponding module.
-
-Use the FTXUI_BUILD_MODULES option to build the FTXUI project itself to provide C++ 20 modules,
-for example with CMake and Ninja:
-
-```sh
-cmake \
-    -DCMAKE_GENERATOR=Ninja \
-    -DFTXUI_BUILD_MODULES=ON \
-    ..
-
-ninja
-```
-
-> [!NOTE]
-> To use modules, you need a C++20 compatible compiler, CMake version 3.20 or
-> higher, and use a compatible generator like Ninja. Note that Makefile
-> generators **do not support modules**.
-
-Then, in your own code you can consume the modules and code as normal:
-
-```cpp
-import ftxui;
-
-int main() {
-  auto screen = ftxui::ScreenInteractive::TerminalOutput();
-  auto button = ftxui::Button("Click me", screen.QuitClosure());
-  screen.Loop(button);
-  return 0;
-}
-```
-
-Note, the `ftxui` convenience module which simply pulls together all the modules:
-
-```cpp
-export import ftxui.component;
-export import ftxui.dom;
-export import ftxui.screen;
-export import ftxui.util;
-```
-You can instead import only the module(s) you need if desired.
-
-To properly find and link the modules with CMake, use `target_link_libraries` to get the right
-compiler, linker, etc. flags.
-
-```cmake
-target_link_libraries(my_executable
-    #...whatever...
-    PRIVATE ftxui::modules
-)
-```
-
-### Module list
-
-The modules directly reference the corresponding header, or a group of related
-headers to provide a more convenient interface. The following modules
-are available:
-
-- `ftxui`
-    - `ftxui.component`
-      - `ftxui.component.Animation`
-      - `ftxui.component.CapturedMouse`

-      - `ftxui.component.Mouse`
-      - `ftxui.component.Receiver`
-      - `ftxui.component.ScreenInteractive`
-      - `ftxui.component.Task`

-# Install FTXUI
-
-To set up FTXUI in your project, follow the [installation guide](installation.html), which provides instructions for multiple build systems and package managers.
-
-# Minimal Example
-
-Save the following code as `main.cpp`:
-
-```cpp
-#include <ftxui/dom/elements.hpp>
-#include <ftxui/screen/screen.hpp>
-#include <iostream>
-
-int main() {
-  using namespace ftxui;
-
-  Element document = hbox({
-    text("left")   | border,
-    text("middle") | border | flex,
-    text("right")  | border,
-  });
-
-  auto screen = Screen::Create(Dimension::Full(), Dimension::Fit(document));
-  Render(screen, document);
-  screen.Print();
-}
-```
-
-Build and run it using your preferred build system.  
-If unsure, start with one of the methods described in the [installation page](installation.html).
-
-Expected output:
-
-```
-┌────┐┌────────────────────────────────────┐┌─────┐
-│left││middle                              ││right│
-└────┘└────────────────────────────────────┘└─────┘
-```
-
-# Starter Template
-
-For a complete working project, clone the official starter repository:
-
-```bash
-git clone https://github.com/ArthurSonzogni/ftxui-starter
-```
-
-Follow the build instructions in the `README.md` of that repository.

-@page installation_cmake CMake
-
-@tableofcontents
-
-This page explains how to depend on FTXUI using [CMake](https://cmake.org).  
-
-# Methods of Integration
-
-## Using FetchContent
-
-This approach downloads FTXUI at configure time and doesn't require a system-wide install.
-
-```cmake 
-include(FetchContent)
-
-FetchContent_Declare(ftxui
-  GIT_REPOSITORY https://github.com/ArthurSonzogni/FTXUI
-  GIT_TAG v6.1.9  # Replace with a version, tag, or commit hash
-)
-
-FetchContent_MakeAvailable(ftxui)
-
-add_executable(main main.cpp)
-target_link_libraries(main
-  PRIVATE ftxui::screen
-  PRIVATE ftxui::dom
-  PRIVATE ftxui::component
-)
-```
-
-This ensures reproducible builds and easy dependency management.
-
-## Using find_package
-
-If FTXUI is installed system-wide or via a package manager (e.g. vcpkg or Conan), you can use:
-
-```cmake 
-find_package(ftxui REQUIRED)
-
-add_executable(main main.cpp)
-target_link_libraries(main
-  PRIVATE ftxui::screen
-  PRIVATE ftxui::dom
-  PRIVATE ftxui::component
-)
-```
-
-Make sure the package is visible in your `CMAKE_PREFIX_PATH`.
-
-## Using git submodule
-
-You can also add FTXUI as a [Git submodule](https://git-scm.com/book/en/v2/Git-Tools-Submodules), keeping it as part of your repository:
-
-```cmake
-git submodule add https://github.com/ArthurSonzogni/FTXUI external/ftxui
-git submodule update --init --recursive
-```
-
-When cloning a repository that already includes FTXUI as a submodule, make sure to fetch submodules with:
-
-```
-git clone --recurse-submodules <your-repo>
-# Or, if already cloned:
-git submodule update --init --recursive
-```
-
-Then in your `CMakeLists.txt`:
-
-```cmake
-add_subdirectory(external/ftxui)
-
-add_executable(main main.cpp)
-target_link_libraries(main
-  PRIVATE ftxui::screen
-  PRIVATE ftxui::dom
-  PRIVATE ftxui::component
-)
-```
-
-This approach works well if you want to vendor FTXUI in your own repository.
-
-# Optional CMake Flags
-
-FTXUI supports the following CMake options:
-
-| Option                            | Description                   | Default |
-| --------------------------------- | ----------------------------- | ------- |
-| FTXUI_BUILD_EXAMPLES              | Build bundled examples        | OFF     |
-| FTXUI_BUILD_DOCS                  | Build the documentation       | OFF     |
-| FTXUI_BUILD_TESTS                 | Enable tests                  | OFF     |
-| FTXUI_ENABLE_INSTALL              | Generate install targets      | ON      |
-| FTXUI_MICROSOFT_TERMINAL_FALLBACK | Improve Windows compatibility | ON/OFF  |
-
-To enable an option:
-
-```
-cmake -DFTXUI_BUILD_EXAMPLES=ON ..
-```
-
-# Verifying Integration
-
-To confirm the setup is working, build and run a minimal example.
-If you need a complete template, see: [ftxui-starter](https://github.com/ArthurSonzogni/ftxui-starter)

-@page installation_conan Conan
-@tableofcontents
-
-FTXUI can be easily obtained and integrated into your project using the Conan package manager.
-
-## Prerequisites
-
-First, ensure that Conan is installed on your system. If not, you can install it via pip:
-
-```powershell
-pip install conan
-```
-Conan often works in tandem with CMake, so you will need to have CMake installed as well. Once you have confirmed both Conan and CMake are installed, create a project directory, for example, `ftxui-demo`:
-
-```powershell
-mkdir C:\ftxui-demo
-cd C:\ftxui-demo
-```
-
-## Configuration
-
-After ensuring your environment is set up correctly, create a Conan configuration file `conanfile.txt`. This file is used to declare your project's dependencies. The community-maintained package for FTXUI can be found on [Conan Center](https://conan.io/center/recipes/ftxui).
-
-> [!note]
-> This is an unofficial build script. This means it is not maintained by the FTXUI
-> team but by the community. The package maintainer appears to actively update it
-> to the latest releases. Many thanks to the maintainer for their work!
-
-@todo If you are familiar with the process, please consider adding an "official" build script to Conan Center.
-This could be a GitHub Action that automatically updates Conan Center upon new releases.
-
-```ini
-[requires]
-ftxui/6.0.2
-
-[generators]
-CMakeDeps
-CMakeToolchain
-
-[layout]
-cmake_layout
-```
-
-## Install Dependencies and Build
-
-Once configured, run the following command to install FTXUI and its dependencies:
-
-```powershell
-conan install . --output-folder=build --build=missing
-```
-
-This will download and install `ftxui/6.0.2` along with all its dependencies from Conan's remote repositories.
-
-After the installation completes, you can test it by creating a `demo.cpp` file in your project directory:
-
-```cpp
-#include <ftxui/screen/screen.hpp>
-#include <ftxui/dom/elements.hpp>
-#include <iostream>
-
-int main() {
-    using namespace ftxui;
-    auto document = hbox({
-        text(" Hello "),
-        text("FTXUI ") | bold | color(Color::Red),
-        text(" world! ")
-    });
-    auto screen = Screen::Create(Dimension::Full(), Dimension::Fit(document));
-    Render(screen, document);
-    std::cout << screen.ToString() << std::endl;
-    return 0;
-}
-```
-
-If the test is successful, you can then create a `CMakeLists.txt` file in the project directory:
-
-```cmake
-cmake_minimum_required(VERSION 3.20)
-project(ftxui-demo)
-
-# Set the C++ standard
-set(CMAKE_CXX_STANDARD 20)
-
-# Find the FTXUI package installed via Conan
-find_package(ftxui CONFIG REQUIRED)
-
-# Create the executable
-add_executable(demo demo.cpp)
-
-# Link the executable to the FTXUI library
-target_link_libraries(demo PRIVATE ftxui::component)
-```
-
-@todo 考虑到中国多数地区使用Conan很有可能遇到各种网络问题，我想做一个定制的版本说明，但是我对conan的了解有限再加上没有找到合适的资料，因此这个计划短暂的被搁置了，如果您知道方法，欢迎在[中文版本](xiaoditx.girhub.io/public/docs/ftxui%E4%B8%AD%E6%96%87%E7%BF%BB%E8%AF%91/installation/conan/)的下方留下评论以提醒我

-   and [React](https://reactjs.org/)
- * No dependencies
- * **Cross platform**.
- * Simple and elegant syntax (in my opinion)
- * Keyboard & mouse navigation.
- * Support for [UTF8](https://en.wikipedia.org/wiki/UTF-8) and [fullwidth chars](https://en.wikipedia.org/wiki/Halfwidth_and_fullwidth_forms) (→ 测试)
- * Support for animations. [Demo 1](https://arthursonzogni.github.io/FTXUI/examples/?file=component/menu_underline_animated_gallery), [Demo 2](https://arthursonzogni.github.io/FTXUI/examples/?file=component/button_style)
- * Support for drawing. [Demo](https://arthursonzogni.github.io/FTXUI/examples/?file=component/canvas_animated)
- * Learn by [examples](#documentation), and [tutorials](#documentation)
- * Multiple build system and packages: 
- * Good practices: documentation, tests, fuzzers, performance tests, automated CI, automated packaging, etc...

+**Short example**
+
+To build a single frame, you need create an `ftxui::Element`, and display it on
+a `ftxui::Screen`.
+
+**main.cpp**
+```cpp
+#include <ftxui/dom/elements.hpp>
+#include <ftxui/screen/screen.hpp>

+
+# List of modules. {#modules}
+
+The project is comprised of 3 modules:
+
+1. **ftxui/screen** defines a `ftxui::Screen`, a grid of `ftxui::Pixel`.
+
+2. **ftxui/dom** is the main module. It defines a hierarchical set of
+   `ftxui::Element`.  An element draws something on the `ftxui::Screen`. It is
+   responsive to the size of its container.
+
+3. **ftxui/component** The module is required if your program needs to respond
+   to user input. It defines a set of `ftxui::Component`. These components can
+   be utilized to navigate the program by using the arrow keys and interacting
+   with widgets such as the checkbox. You can also make you own components.
+   The use can navigates
+   using the arrow keys and interact with widgets like checkbox/inputbox/... You
+   can make you own components.
+
+# screen {#module-screen}
+
+This is the visual element of the program. It defines a `ftxui::Screen`, which
+is a grid of `ftxui::Pixel`. A Pixel represents a Unicode character and its
+associated style (bold, colors, etc.). The screen can be printed as a string
+using `ftxui::Screen::ToString()`. The following example highlights this
+process:
+
+```cpp
+  #include <ftxui/screen/screen.hpp>
+  #include <iostream>
+
+  int main(void) {
+    using namespace ftxui;
+    auto screen = Screen::Create(Dimension::Fixed(32), Dimension::Fixed(10));
+
+    auto& pixel = screen.PixelAt(9,9);
+    pixel.character = U'A';
+    pixel.bold = true;
+    pixel.foreground_color = Color::Blue;
+
+    std::cout << screen.ToString();
+    return EXIT_SUCCESS;
+  }
+```

+This module defines a hierarchical set of `ftxui::Element`. An element manages
+the layout and can be responsive to the terminal dimension changes. Note the
+following example where this module is used to create a simple layout with a
+number of operators:
+
+**Example:**
+```cpp
+// Define the document
+Element document = vbox({
+  text("The window") | bold | color(Color::Blue),
+  gauge(0.5)
+  text("The footer")
+});
+
+// Add a border, by calling the `ftxui::border` decorator function.
+document = border(document);
+
+// Add another border, using the pipe operator.
+document = document | border.
+
+// Add another border, using the |= operator.
+document |= border
+
+```
+
+**List of elements**
+
+The list of all elements are included and can be accessed by including the
+corresponding header file:
+```cpp
+#include <ftxui/dom/elements.hpp>
+```
+
+\include ftxui/dom/elements.hpp
+
+## text ## {#dom-text}
+
+The most simple widget. It displays a text.
+```cpp
+text("I am a piece of text");
+```
+```bash
+I am a piece of text.
+```
+
+## vtext {#dom-vtext}
+
+Identical to `ftxui::text`, but displayed vertically.
+
+Code:
+```cpp
+vtext("HELLO");
+```
+
+Terminal output:
+```bash
+H
+E
+L
+L
+O
+```
+
+## paragraph {#dom-paragraph}
+
+Similar to `ftxui::text`, but the individual word are wrapped along multiple
+lines, depending on the width of its container.
+
+Sample Code:
+```cpp
+paragraph("A very long text")
+```
+

+
+For a more detailed example refer to [detailed example](https://arthursonzogni.github.io/FTXUI/examples_2dom_2paragraph_8cpp-example.html). Paragraph also includes a number of other variants as shown below:
+```cpp
+Element paragraph(std::string text);
+Element paragraphAlignLeft(std::string text);
+Element paragraphAlignRight(std::string text);
+Element paragraphAlignCenter(std::string text);
+Element paragraphAlignJustify(std::string text);
+```
+
+
+## border {#dom-border}
+
+Adds a border around an element.
+
+Code:
+```cpp
+border(text("The element"))
+```
+
+Terminal output:
+```bash
+┌───────────┐
+│The element│
+└───────────┘
+```
+
+You can achieve the same behavior by using the pipe operator.
+
+Code:
+```cpp
+text("The element") | border
+```
+
+Border also comes in a variety of styles as shown below:
+```cpp
+Element border(Element);
+Element borderLight(Element);
+Element borderHeavy(Element);
+Element borderDouble(Element);
+Element borderRounded(Element);
+Element borderEmpty(Element);
+Decorator borderStyled(BorderStyle);
+Decorator borderWith(Pixel);
+```
+
+
+## window ## {#dom-window}
+
+A `ftxui::window` is a `ftxui::border`, but with an additional header. To add a
+window around an element, wrap it and specify a string as the header.
+Code:
+```cpp
+window("The window", text("The element"))
+```
+
+Terminal output:
+```bash
+┌The window─┐
+│The element│
+└───────────┘
+```
+
+## separator {#dom-separator}
+
+Displays a vertical/horizontal line to visually split the content of a
+container in two.
+
+Code:
+```cpp
+border(
+  hbox({
+    text("Left"), 
+    separator(),
+    text("Right")
+  })
+)
+```
+
+Terminal output:
+```bash
+┌────┬─────┐
+│left│right│
+└────┴─────┘
+```
+
+
+Separators come in a variety of flavors as shown below:
+```cpp
+Element separator(void);
+Element separatorLight();
+Element separatorHeavy();
+Element separatorDouble();
+Element separatorEmpty();
+Element separatorStyled(BorderStyle);
+Element separator(Pixel);
+Element separatorCharacter(std::string);
+Element separatorHSelector(float left,
+                           float right,
+                           Color background,
+                           Color foreground);
+Element separatorVSelector(float up,
+                           float down,
+                           Color background,
+                           Color foreground);
+```
+
+## gauge {#dom-gauge}
+
+It constitutes a gauge. It can be used to represent a progress bar.
+
+Code:
+```cpp
+border(gauge(0.5))
+```
+
+Teminal output:
+```bash
+┌────────────────────────────────────────────────────────────────────────────┐

+
+Gauges can be displayed in many orientations as shown below:
+```cpp
+Element gauge(float ratio);
+Element gaugeLeft(float ratio);
+Element gaugeRight(float ratio);
+Element gaugeUp(float ratio);
+Element gaugeDown(float ratio);
+Element gaugeDirection(float ratio, GaugeDirection);

+
+## Colors {#dom-colors}
+
+Most terminal consoles can display colored text and colored backgrounds. FTXUI
+supports every color palette:
+```cpp
+Decorator color(Color);
+Decorator bgcolor(Color);
+```
+
+
+Color [gallery](https://arthursonzogni.github.io/FTXUI/examples_2dom_2color_gallery_8cpp-example.html):
+![image](https://user-images.githubusercontent.com/4759106/147248595-04c7245a-5b85-4544-809d-a5984fc6f9e7.png)
+
+### Palette16 #{#dom-colors-palette-16}
+
+On most terminals the following colors are supported:
+- Default
+
+- Black
+- GrayDark
+- GrayLight
+
+- White
+
+- Blue
+- BlueLight
+
+- Cyan
+- CyanLight
+
+- Green
+- GreenLight
+
+- Magenta
+- MagentaLight
+
+- Red
+- RedLight
+
+- Yellow
+- YellowLight
+
+Example use of the above colors using the pipe operator:
+```cpp
+text("Blue foreground") | color(Color::Blue);
+text("Blue background") | bgcolor(Color::Blue);
+text("Black on white") | color(Color::Black) | bgcolor(Color::White);
+```
+
+### Palette256 #{#dom-colors-palette-256}
+
+On terminal supporting 256 colors. 
+@htmlonly
+<script id="asciicast-OAUc3n6QrkmrLt7XEEb8AzbLt" src="https://asciinema.org/a/OAUc3n6QrkmrLt7XEEb8AzbLt.js" async></script>
+@endhtmlonly
+
+```cpp
+text("HotPink") | color(Color::HotPink);
+```
+
+### TrueColor #{#dom-colors-true-color}
+
+On terminal supporting trueColor, you can directly use the 24bit RGB color
+space:
+
+Use the constructors below to specify the **RGB** or **HSV** values for your
+color:
+
+There are two constructors:
+```cpp
+ftxui::Color::RGB(uint8_t red, uint8_t green, uint8_t blue);
+ftxui::Color::HSV(uint8_t hue, uint8_t saturation, uint8_t value);
+```

+@endhtmlonly
+
+## LinearGradient #{#dom-linear-gradient}
+
+FTXUI supports linear gradient. Either on the foreground or the background.
+
+```cpp
+Decorator color(const LinearGradient&);
+Decorator bgcolor(const LinearGradient&);
+```
+
+A `ftxui::LinearGradient` is defined by an angle in degree, and a list of color
+stops.
+```cpp
+auto gradient = LinearGradient()
+  .Angle(45)
+  .AddStop(0.0, Color::Red)
+  .AddStop(0.5, Color::Green)
+  .AddStop(1.0, Color::Blue);
+```
+
+You can also use simplified constructors:
+```cpp
+LinearGradient(Color::Red, Color::Blue);
+```
+```cpp
+LinearGradient(45, Color::Red, Color::Blue);
+```
+
+See [demo](https://arthursonzogni.github.io/FTXUI/examples/?file=component/linear_gradient_gallery).
+
+
+## Style {#dom-style}
+In addition to colored text and colored backgrounds. Many terminals support text
+effects such as: `bold`, `dim`, `underlined`, `inverted`, `blink`.
+
+```cpp
+Element bold(Element);
+Element dim(Element);
+Element inverted(Element);
+Element underlined(Element);
+Element underlinedDouble(Element);
+Element strikethrough(Element);
+Element blink(Element);
+Decorator color(Color);
+Decorator bgcolor(Color);
+Decorator colorgrad(LinearGradient);
+Decorator bgcolorgrad(LinearGradient);
+```
+
+[Example](https://arthursonzogni.github.io/FTXUI/examples_2dom_2style_gallery_8cpp-example.html)
+
+![image](https://user-images.githubusercontent.com/4759106/147244118-380bf834-9e33-40df-9ff0-07c10f2598ef.png)
+
+To use these effects, simply wrap your elements with your desired effect:
+```cpp
+underlined(bold(text("This text is bold and underlined")))
+```
+
+Alternatively, use the pipe operator to chain it on your element:
+```cpp
+text("This text is bold") | bold | underlined
+```
+
+## Layout {#dom-layout}
+
+Enables elements to be arranged in the following ways:
+  - **Horizontally** with `ftxui::hbox`
+  - **Vertically** with `ftxui::vbox`
+  - **Inside a grid** with `ftxui::gridbox`
+  - **Wrapped along one direction** using the `ftxui::flexbox`.
+  
+[Example](https://arthursonzogni.github.io/FTXUI/examples_2dom_2vbox_hbox_8cpp-example.html) using `ftxui::hbox`, `ftxui::vbox` and `ftxui::filler`.

+
+Element can also become flexible using the the `ftxui::flex` decorator.
+
+Code:
+```cpp
+  hbox({
+    text("left") | border ,
+    text("middle") | border | flex,
+    text("right") | border,

+  auto element = canvas(c);
+```
+
+Drawing can be performed on a `ftxui::Canvas`, using braille, block, or simple
+characters:

+# component {#module-component}
+
+The `ftxui::component` module defines the logic that produces interactive
+components that respond to user events (keyboard, mouse, etc.).
+
+A `ftxui::ScreenInteractive` defines a main loop that renders a component.
+
+A `ftxui::Component` is a shared pointer to a `ftxui::ComponentBase`. The latter defines:
+  - `ftxui::ComponentBase::Render()`: How to render the interface.
+  - `ftxui::ComponentBase::OnEvent()`: How to react to events.
+  - `ftxui::ComponentBase::Add()`: Construct a parent/child relationship
+    between two components. The tree of component is used to define how to
+    navigate using the keyboard.
+
+`ftxui::Element` are used to render a single frame.
+
+`ftxui::Component` are used to render dynamic user interface, producing multiple
+frame, and updating its state on events.
+
+[Gallery](https://arthursonzogni.github.io/FTXUI/examples_2component_2gallery_8cpp-example.html) of multiple components. ([demo](https://arthursonzogni.github.io/FTXUI/examples/?file=component/gallery))

+## Slider {#component-slider}
+
+Represents a slider object that consists of a range with binned intermediate
+intervals. It can be created by `ftxui::Slider()`.
+
+[Example](https://arthursonzogni.github.io/FTXUI/examples_2component_2slider_8cpp-example.html):

+
+## Renderer {#component-renderer}
+
+Produced by: `ftxui::Renderer()` from \ref ftxui/component/component.hpp. This
+component decorate another one by using a different function to render an
+interface.
+
+Example:
+```cpp
+auto inner = [...]
+
+auto renderer = Renderer(inner, [&] {
+  return inner->Render() | border
+});
+```
+
+`ftxui::Renderer` also supports the component decorator pattern:
+```cpp
+auto component = [...]
+component = component
+  | Renderer([](Element e) { return e | border))
+  | Renderer(bold)
+```
+
+As a short hand, you can also compose a component with an element decorator:
+```cpp
+auto component = [...]
+component = component | border | bold;
+```
+
+## CatchEvent {#component-catchevent}
+
+Produced by: `ftxui::CatchEvent()` from \ref ftxui/component/component.hpp.
+This component decorate others, catching events before the underlying component.
+
+Examples:
+```cpp
+auto screen = ScreenInteractive::TerminalOutput();
+auto renderer = Renderer([] {
+  return text("My interface");
+});
+auto component = CatchEvent(renderer, [&](Event event) {
+  if (event == Event::Character('q')) {
+    screen.ExitLoopClosure()();
+    return true;
+  }
+  return false;
+});
+screen.Loop(component);
+```
+
+The `ftxui::CatchEvent` can also be used as a decorator:
+```cpp
+component = component
+  | CatchEvent(handler_1)
+  | CatchEvent(handler_2)
+  | CatchEvent(handler_3)
+  ;
+```
+
+## Collapsible {#component-collapsible}
+
+Useful for visual elements whose visibility can be toggle on/off by the user.
+Essentially, this the combination of the `ftxui::Checkbox()` and
+`ftxui::Maybe()` components.
+
+```cpp
+auto collabsible = Collapsible("Show more", inner_element);
+```
+
+## Maybe {#component-maybe}
+
+Produced by: `ftxui::Maybe()` from \ref ftxui/component/component.hpp.
+This component can be utilized to show/hide any other component via a boolean or
+a predicate.
+
+Example with a boolean:
+```cpp
+bool show = true;
+auto component = Renderer([]{ return "Hello World!"; });
+auto maybe_component = Maybe(component, &show)
+```
+
+Example with a predicate:
+```cpp
+auto component = Renderer([]{ return "Hello World!"; });
+auto maybe_component = Maybe(component, [&] { return time > 10; })
+```
+
+As usual, `ftxui::Maybe` can also be used as a decorator:
+```cpp
+component = component
+  | Maybe(&a_boolean)
+  | Maybe([&] { return time > 10; })
+  ;
+```
+
+## Container {#component-container}
+
+### Horizontal {#component-horizontal}
+
+Produced by: `ftxui::Container::Horizontal()` from
+"ftxui/component/component.hpp". It displays a list of components horizontally
+and handle keyboard/mouse navigation.
+
+### Vertical {#component-vertical}
+
+Produced by: `ftxui::Container::Vertical()` from
+"ftxui/component/component.hpp". It displays a list of components vertically 
+and handles keyboard/mouse navigation.
+
+### Tab {#component-tab}
+
+Produced by: `ftxui::Container::Tab()` from
+"ftxui/component/component.hpp". It take a list of component and display only
+one of them. This is useful for implementing a tab bar.

+## Force a frame redraw. {#component-force-redraw}
+
+Typically, `ftxui::ScreenInteractive::Loop()` is responsible for drawing a new
+frame whenever a new group of events (e.g keyboard, mouse, window resize, etc.)
+has been processed. However, you might want to react to arbitrary events that
+are unknown to FTXUI. To accomplish this, you must post events using
+`ftxui::ScreenInteractive::PostEvent` (**this is thread safe**) via a thread.
+You will have to post the event `ftxui::Event::Custom`.

-The `ftxui::component` module defines the logic that produces interactive
-components that respond to user events (keyboard, mouse, etc.).
-
-The @subpage module-component-examples section provides a collection of examples.
-
-A `ftxui::ScreenInteractive` defines a main loop that renders a component.
-
-A `ftxui::Component` is a shared pointer to a `ftxui::ComponentBase`. The latter defines:
-  - `ftxui::ComponentBase::Render()`: How to render the interface.
-  - `ftxui::ComponentBase::OnEvent()`: How to react to events.
-  - `ftxui::ComponentBase::Add()`: Construct a parent/child relationship
-    between two components. The tree of components is used to define how to
-    navigate using the keyboard.
-
-`ftxui::Element` are used to render a single frame.
-
-`ftxui::Component` are used to render dynamic user interface, producing multiple
-frame, and updating its state on events.

-
-# Renderer {#component-renderer}
-
-Produced by: `ftxui::Renderer()` from \ref ftxui/component/component.hpp. This
-component decorate another one by using a different function to render an
-interface.
-
-Example:
-```cpp
-auto inner = [...]
-
-auto renderer = Renderer(inner, [&] {
-  return inner->Render() | border
-});
-```
-
-`ftxui::Renderer` also supports the component decorator pattern:
-```cpp
-auto component = [...]
-component = component
-  | Renderer([](Element e) { return e | border))
-  | Renderer(bold)
-```
-
-As a short hand, you can also compose a component with an element decorator:
-```cpp
-auto component = [...]
-component = component | border | bold;
-```
-
-# CatchEvent {#component-catchevent}
-
-Produced by: `ftxui::CatchEvent()` from \ref ftxui/component/component.hpp.
-This component decorate others, catching events before the underlying component.
-
-Examples:
-```cpp
-auto screen = ScreenInteractive::TerminalOutput();
-auto renderer = Renderer([] {
-  return text("My interface");
-});
-auto component = CatchEvent(renderer, [&](Event event) {
-  if (event == Event::Character('q')) {
-    screen.ExitLoopClosure()();
-    return true;
-  }
-  return false;
-});
-screen.Loop(component);
-```
-
-The `ftxui::CatchEvent` can also be used as a decorator:
-```cpp
-component = component
-  | CatchEvent(handler_1)
-  | CatchEvent(handler_2)
-  | CatchEvent(handler_3)
-  ;
-```
-
-# Collapsible {#component-collapsible}
-
-Useful for visual elements whose visibility can be toggled on or off by the
-user. Essentially, this is the combination of the `ftxui::Checkbox()` and
-`ftxui::Maybe()` components.
-
-```cpp
-auto collapsible = Collapsible("Show more", inner_element);
-```
-
-# Maybe {#component-maybe}
-
-Produced by: `ftxui::Maybe()` from \ref ftxui/component/component.hpp.
-This component can be utilized to show/hide any other component via a boolean or
-a predicate.
-
-Example with a boolean:
-```cpp
-bool show = true;
-auto component = Renderer([]{ return "Hello World!"; });
-auto maybe_component = Maybe(component, &show)
-```
-
-Example with a predicate:
-```cpp
-auto component = Renderer([]{ return "Hello World!"; });
-auto maybe_component = Maybe(component, [&] { return time > 10; })
-```
-
-As usual, `ftxui::Maybe` can also be used as a decorator:
-```cpp
-component = component
-  | Maybe(&a_boolean)
-  | Maybe([&] { return time > 10; })
-  ;
-```
-
-# Container {#component-container}
-
-## Horizontal {#component-horizontal}
-
-Produced by: `ftxui::Container::Horizontal()` from
-"ftxui/component/component.hpp". It displays a list of components horizontally
-and handles keyboard/mouse navigation.
-
-## Vertical {#component-vertical}
-
-Produced by: `ftxui::Container::Vertical()` from
-"ftxui/component/component.hpp". It displays a list of components vertically 
-and handles keyboard/mouse navigation.
-
-## Tab {#component-tab}
-
-Produced by: `ftxui::Container::Tab()` from
-"ftxui/component/component.hpp". It takes a list of components and displays
-only one of them. This is useful for implementing a tab bar.

-You can also use simplified constructors:
-```cpp
-LinearGradient(Color::Red, Color::Blue);
-```
-```cpp
-LinearGradient(45, Color::Red, Color::Blue);
-```

-# Style {#dom-style}
-In addition to colored text and colored backgrounds. Many terminals support text
-effects such as: `bold`, `italic`, `dim`, `underlined`, `inverted`, `blink`.
-
-```cpp
-Element bold(Element);
-Element italic(Element);
-Element dim(Element);
-Element inverted(Element);
-Element underlined(Element);
-Element underlinedDouble(Element);
-Element strikethrough(Element);
-Element blink(Element);
-Decorator color(Color);
-Decorator bgcolor(Color);
-Decorator colorgrad(LinearGradient);
-Decorator bgcolorgrad(LinearGradient);
-```

-
-To use these effects, simply wrap your elements with your desired effect:
-```cpp
-underlined(bold(text("This text is bold and underlined")))
-```
-
-Alternatively, use the pipe operator to chain it on your element:
-```cpp
-text("This text is bold") | bold | underlined
-```
-
-# Layout {#dom-layout}
-
-Enables elements to be arranged in the following ways:
-  - **Horizontally** with `ftxui::hbox`
-  - **Vertically** with `ftxui::vbox`
-  - **Inside a grid** with `ftxui::gridbox`
-  - **Wrapped along one direction** using the `ftxui::flexbox`.
-  
-[Example](https://arthursonzogni.github.io/FTXUI/examples_2dom_2vbox_hbox_8cpp-example.html) using `ftxui::hbox`, `ftxui::vbox` and `ftxui::filler`.

-
-The `ftxui::screen` module is the low-level foundation. It can be used
-standalone, but it is primarily designed to be used together by
-[ftxui::dom](module-dom.html) and [ftxui::component](module-component.html)
-modules.
-
-It provides a @ref ftxui::Screen.
-
----
-
-# ftxui::Screen
-
-The @ref ftxui::Screen class represents a 2D grid of styled characters that can
-be rendered to a terminal.  
-It provides methods to create a screen, access pixels, and render elements.
-
-You can access the individual cells (@ref ftxui::Pixel) of the screen using 
-the @ref ftxui::Screen::PixelAt method, which returns a reference
-to the pixel at the specified coordinates.
-
-**Example**
-```cpp
-#include <ftxui/screen/screen.hpp>
-#include <ftxui/screen/color.hpp>
-
-void main() {
-    auto screen = ftxui::Screen::Create(
-        ftxui::Dimension::Full(),   // Use full terminal width
-        ftxui::Dimension::Fixed(10) // Fixed height of 10 rows
-    );
-
-    // Access a specific pixel at (10, 5)
-    auto& pixel = screen.PixelAt(10, 5);
-
-    // Set properties of the pixel.
-    pixel.character = U'X';
-    pixel.foreground_color = ftxui::Color::Red;
-    pixel.background_color = ftxui::Color::RGB(0, 255, 0);
-    pixel.bold = true; // Set bold style
-    screen.Print(); // Print the screen to the terminal
-}
-```
-
-> [!note]
-> If the coordinates are out of bounds, a dummy pixel is returned.
-
-The screen can be printed to the terminal using @ref ftxui::Screen::Print() or
-converted to a std::string with @ref ftxui::Screen::ToString().
-
-<div class="tabbed">
- 
-- <b class="tab-title">Print()</b>
-  ```cpp
-  auto screen = ...;
-  screen.Print();
-  ```
-- <b class="tab-title">ToString()</b>
-  ```cpp
-  auto screen = ...;
-  std::cout << screen.ToString();
-  ```
- 
-</div>
-
-Note that you can reset the cursor position to the top-left corner of the
-screen after printing by calling @ref ftxui::Screen::ResetCursorPosition().
-
-**Example**
-```cpp
-auto screen = ...;
-while(true) {
-  // Drawing operations:
-  ...
-  
-  // Print the screen to the terminal. Then reset the cursor position and the
-  // screen content.
-  std::cout << screen.ToString();
-  std::cout << screen.ResetCursorPosition(/*clear=*/true);
-  std::cout << std::flush;
-
-  // Sleep for a short duration to control the refresh rate.
-  std::this_thread::sleep_for(std::chrono::milliseconds(100));
-}
-```
-
----
-
-# ftxui::Dimension
-
-The @ref ftxui::Dimension utility controls screen sizing:
-
-* `Dimension::Full()` — use full terminal width or height
-* `Dimension::Fit(element)` — size to fit the rendered @ref ftxui::Element
-* `Dimension::Fixed(n)` — use exactly `n` columns or rows
-
-These values are to be passed to `ftxui::Screen::Create()`.
-
-@ref ftxui::Screen::Create() provides two overloads:
-
-- `Screen::Create(Dimension)` sets both width and height to the same kind of dimension
-- `Screen::Create(Dimension width, Dimension height)` allows distinct control per axis
-
-```cpp
-auto screen = ftxui::Screen::Create(
-  ftxui::Dimension::Full(),      // width
-  ftxui::Dimension::Fixed(10)    // height
-);
-```
-
-Once created, render an element and display the result:
-
-```cpp
-ftxui::Render(screen, element);
-screen.Print();
-```
-
----
-
-# ftxui::Pixel
-
-Each cell in the screen grid is a @ref ftxui::Pixel, which holds:
-
-- Unicode codepoint.
-    - `character`
-- @ref ftxui::Color:
-    - `foreground_color`
-    - `background_color`
-- Booleans:
-    - `blink`
-    - `bold`
-    - `dim`
-    - `italic`
-    - `inverted` (swap foreground and background colors)
-    - `underlined`
-    - `underlined_double`
-    - `strikethrough`
-
-
-```cpp
-auto screen = ftxui::Screen::Create(
-  ftxui::Dimension::Fixed(5),
-  ftxui::Dimension::Fixed(5),
-);
-
-auto& pixel = screen.PixelAt(3, 3);
-pixel.character = U'X';
-pixel.bold = true;
-pixel.foreground_color = ftxui::Color::Red;
-pixel.background_color = ftxui::Color::RGB(0, 255, 0);
-
-screen.Print();
-```
-
-> [!note]
-> `PixelAt(x, y)` performs bounds checking and returns a reference to the pixel
-> at the specified coordinate. If out-of-bounds, a dummy pixel reference is
-> returned.
-
-
-Each cell in the screen is a @ref ftxui::Pixel. You can modify them using:
-
-```cpp
-auto& pixel = screen.PixelAt(x, y);
-pixel.character = U'X';
-pixel.bold = true;
-pixel.foreground_color = Color::Red;
-```
-
----
-
-# ftxui::Color
-
-The @ref ftxui::Color class is used to define foreground and background colors for each @ref ftxui::Pixel.
-
-It supports various color spaces and predefined palettes. FTXUI will
-dynamically fallback to the closest available color in the terminal if the
-requested color is not supported by the terminal.
-
-**Color Spaces**
-
-- **Default**: `ftxui::Color::Default` (terminal's default color)
-- **16-color palette** [Demo](https://arthursonzogni.github.io/FTXUI/examples/?file=dom/color_gallery):
-    - `ftxui::Color::Black`,
-    - `ftxui::Color::Red`,
-    - ...
-- **256-color palette** [Demo](https://arthursonzogni.github.io/FTXUI/examples/?file=dom/color_palette256):
-    - `ftxui::Color::Chartreuse1`,
-    - `ftxui::Color::DarkViolet`,
-    - ...
-- **True color** (24bit) [Demo](https://arthursonzogni.github.io/FTXUI/examples/?file=dom/color_truecolor_HSV:
-    - `ftxui::Color::RGB(uint8_t red, uint8_t green, uint8_t blue)`
-    - `ftxui::Color::HSV(uint8_t h, uint8_t s, uint8_t v)`.
-    
-
-> [!note]
-> You can query the terminal capability using @ref ftxui::Terminal::ColorSupport();
->
-> This can manually be set using @ref ftxui::Terminal::SetColorSupport().
