-# FTXUI - Functional Terminal (X) User Interface
-
-FTXUI is a cross-platform C++ library for terminal-based user interfaces with a functional programming approach, inspired by React.
-
-**ALWAYS reference these instructions first and fallback to search or bash commands only when you encounter unexpected information that does not match the information here.**
-
-## Working Effectively
-
-### Build System Setup and Commands
-- Bootstrap and build the repository:
-  ```bash
-  # Basic build (library only) - fast
-  cmake -S . -B build -DCMAKE_BUILD_TYPE=Release
-  cmake --build build --parallel $(nproc)
-  # Build time: ~30 seconds. NEVER CANCEL. Set timeout to 120+ seconds.
-  
-  # Build with examples  
-  cmake -S . -B build -DCMAKE_BUILD_TYPE=Release -DFTXUI_BUILD_EXAMPLES=ON
-  cmake --build build --parallel $(nproc)
-  # Build time: ~70 seconds. NEVER CANCEL. Set timeout to 180+ seconds.
-  
-  # Build with examples and tests
-  cmake -S . -B build -DCMAKE_BUILD_TYPE=Release -DFTXUI_BUILD_EXAMPLES=ON -DFTXUI_BUILD_TESTS=ON
-  cmake --build build --parallel $(nproc)
-  # Build time: ~113 seconds (includes GoogleTest download). NEVER CANCEL. Set timeout to 300+ seconds.
-  ```
-
-- Alternative build with Ninja (faster):
-  ```bash
-  cmake -S . -B build -G Ninja -DCMAKE_BUILD_TYPE=Release -DFTXUI_BUILD_EXAMPLES=ON
-  ninja -C build
-  # Build time: ~62 seconds. NEVER CANCEL. Set timeout to 180+ seconds.
-  ```
-
-- Run unit tests:
-  ```bash
-  # Configure with tests enabled first, then:
-  cd build && ctest --output-on-failure
-  # Test time: ~4 seconds (302 tests). NEVER CANCEL. Set timeout to 60+ seconds.
-  ```
-
-### Bazel Support
-- FTXUI also supports Bazel build system
-- **WARNING**: Bazel may fail due to network connectivity issues in sandboxed environments
-- If Bazel is available:
-  ```bash
-  bazel build //...  # Build everything
-  bazel test //...   # Run tests
-  ```
-
-## Validation
-
-### Manual Testing After Changes
-- **ALWAYS manually validate changes by building and running examples after making code modifications**
-- Run example applications to verify functionality:
-  ```bash
-  # Build an example first
-  cmake --build build --target ftxui_example_border
-  
-  # Run examples (they are interactive, use timeout to terminate)
-  timeout 2s build/examples/dom/ftxui_example_border
-  timeout 2s build/examples/dom/ftxui_example_color_gallery
-  timeout 2s build/examples/component/ftxui_example_button
-  ```
-- Examples should produce visual terminal output with borders, colors, and UI components
-- **CRITICAL**: Always run at least one DOM example and one Component example to verify both modules work
-
-### Code Quality and Formatting
-- Always run formatting before committing:
-  ```bash
-  ./tools/format.sh
-  # Format time: ~7 seconds. NEVER CANCEL. Set timeout to 60+ seconds.
-  ```
-- The format script adds license headers and runs clang-format on all source files
-- **Required**: Run formatting or the CI (.github/workflows/build.yaml) will fail
-
-### Build Validation Requirements
-- ALWAYS build with both `-DFTXUI_BUILD_EXAMPLES=ON` and `-DFTXUI_BUILD_TESTS=ON` when making changes
-- Run the complete test suite with `ctest --output-on-failure`
-- All 302 tests must pass
-- **Scenario Testing**: Run at least these validation scenarios:
-  1. Build library only (basic validation)
-  2. Build with examples and run 2-3 different examples
-  3. Build with tests and run complete test suite
-  4. Run formatting tool to ensure code style compliance

-### Core Library Modules
-FTXUI is organized into three main modules that depend on each other:
-```
-┌component──┐  (Interactive UI components)
-│┌dom──────┐│  (Layout and styling elements)  
-││┌screen─┐││  (Terminal rendering and input)
-└┴┴───────┴┴┘
-```
-
-1. **screen**: Low-level terminal handling, colors, pixels, input
-2. **dom**: Layout elements (hbox, vbox, text, borders, etc.)
-3. **component**: Interactive components (buttons, menus, input fields)
-
-### CMake Build Options
-| Option                            | Description                      | Default |
-|-----------------------------------|----------------------------------|---------|
-| FTXUI_BUILD_EXAMPLES              | Build example applications       | OFF     |
-| FTXUI_BUILD_DOCS                  | Build documentation             | OFF     |  
-| FTXUI_BUILD_TESTS                 | Build and enable tests          | OFF     |
-| FTXUI_BUILD_MODULES               | Build C++20 modules             | OFF     |
-| FTXUI_ENABLE_INSTALL              | Generate install targets        | ON      |
-| FTXUI_MICROSOFT_TERMINAL_FALLBACK | Windows terminal compatibility  | ON/OFF  |
-
-## Common Tasks
-
-### Building Examples
-```bash
-# Build specific examples
-cmake --build build --target ftxui_example_border
-cmake --build build --target ftxui_example_button
-cmake --build build --target ftxui_example_menu
-
-# List all available examples
-find build -name "ftxui_example_*" -type f
-```
-
-### Running Tests
-```bash
-# Run all tests
-cd build && ctest
-
-# Run tests with verbose output
-cd build && ctest --verbose
-
-# Run specific test pattern
-cd build && ctest -R "Button" --verbose
-```
-
-### Working with Source Code
-- **Component Development**: Modify files in `src/ftxui/component/` for interactive elements
-- **DOM Development**: Modify files in `src/ftxui/dom/` for layout and styling
-- **Screen Development**: Modify files in `src/ftxui/screen/` for terminal rendering
-- **Adding Examples**: Add new `.cpp` files in `examples/component/` or `examples/dom/`
-- **Header Files**: Public APIs are in `include/ftxui/[module]/`
-
-### Integration Patterns
-When adding FTXUI to a project, use CMake FetchContent (recommended):
-```cmake
-include(FetchContent)
-FetchContent_Declare(ftxui
-  GIT_REPOSITORY https://github.com/ArthurSonzogni/ftxui
-  GIT_TAG v6.1.9
-)
-FetchContent_MakeAvailable(ftxui)
-
-target_link_libraries(your_target PRIVATE
-    ftxui::component  # For interactive components
-    ftxui::dom        # For layout elements  
-    ftxui::screen     # For basic rendering
-)
-```
-
-## Troubleshooting
-
-### Build Issues
-- If CMake configuration fails, ensure C++20 support: `cmake --version` (need 3.12+)
-- If Ninja build fails, fall back to Make: `cmake -S . -B build` (without `-G Ninja`)
-- If tests fail to build, GoogleTest download might have failed - check network connectivity
-- Build artifacts are in `build/` directory - delete with `rm -rf build` to clean
-
-### Example Issues  
-- Examples are interactive terminal applications - use `timeout` to terminate them
-- If examples don't display correctly, terminal might not support colors/Unicode
-- Examples require terminal size of at least 80x24 for proper display
-
-### Formatting Issues
-- Format script requires clang-format to be installed
-- If format script fails, check that source files are not read-only
-- Format script modifies files in-place - commit changes afterwards
-
-## Critical Reminders
-
-- **NEVER CANCEL long-running builds** - they may take 2-3 minutes
-- **ALWAYS run the formatting tool** before committing changes  
-- **ALWAYS build and test examples** when making component/dom changes
-- **SET APPROPRIATE TIMEOUTS**: 300+ seconds for builds, 60+ seconds for tests
-- **BUILD TIMING EXPECTATIONS**:
-  - Basic library: ~30 seconds
-  - With examples: ~70 seconds  
-  - With examples + tests: ~113 seconds (first time, includes GoogleTest download)
-  - Subsequent builds: ~60-70 seconds
-  - Tests execution: ~4 seconds
-  - Formatting: ~7 seconds

-# FTXUI Bazel Integration Test
-
-This directory contains integration tests to verify that FTXUI can be properly consumed as an external dependency using Bazel with Bzlmod.
-
-## Purpose
-
-These tests ensure that:
-- FTXUI's public API is correctly exposed to external projects
-- Both single-target (`@ftxui//:ftxui`) and submodule-based dependencies work correctly
-- Headers are properly re-exported and accessible from downstream projects
-
-## Build Instructions
-
-To build all targets:
-
-```bash
-bazel build //... --enable_bzlmod --override_module=ftxui=../..
-```
-
-To build individual targets:
-
-```bash
-# Test using individual submodules
-bazel build //:smoke --enable_bzlmod --override_module=ftxui=../..
-
-# Test using the single ftxui target
-bazel build //:smoke_single_dependency --enable_bzlmod --override_module=ftxui=../..
-```
-
-## Run the Examples
-
-```bash
-# Run the submodules version
-./bazel-bin/smoke
-
-# Run the single-target version
-./bazel-bin/smoke_single_dependency
-```

-FTXUI can be easily obtained and integrated into your project using the Conan package manager.
+Unofficial recipe for FTXUI exists on Conan Center:
-
+<https://conan.io/center/recipes/ftxui>
-## 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]

+> the package to the latest version. Thanks to the maintainers 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
+@todo Add instructions on how to use the conan recipe.

-```
-
-## 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)
-```

-# POSIX Piped Input in FTXUI
-
-> [!WARNING]
-> This feature works only on Linux and macOS. It is not supported on
-> Windows and WebAssembly.
-
-## What is a POSIX Pipe?
-
-A POSIX pipe is a way for two separate programs to communicate. One program sends its output directly as input to another program. Think of it like a one-way tube for data.
-
-**Example:**
-
-Imagine you want to list files and then filter them interactively.
-
-- `ls`: Lists files.
-- `interactive_grep`: An FTXUI application that filters text and lets you type.
-
-You can connect them with a pipe (`|`):
-
-```bash
-ls -l | interactive_grep
-```
-
-Here's what happens:
-1. `ls -l` lists files with details.
-2. The `|` sends this list directly to `interactive_grep`.
-3. `interactive_grep` receives the list and displays it. Because it's an FTXUI app, you can then type to filter the list, even though it received initial data from `ls`.
-
-## How FTXUI Handles Piped Input
-
-Now that you understand what a POSIX pipe is, let's look at how FTXUI uses them.
-
-FTXUI lets your application read data from other programs (like from a pipe) while still allowing you to use your keyboard for interaction. This is useful for interactive command-line tools that process data.
-
-Normally, FTXUI applications receive all input from `stdin`. However, when FTXUI detects that `stdin` is connected to the output of a pipe (meaning data is being piped into your application), it automatically switches to reading interactive keyboard input from `/dev/tty`. This ensures that your application can still receive user input even while processing piped data.
-
-This feature is **turned on by default**.
-
-If your FTXUI application needs to read piped data and also respond to keyboard input, you typically don't need to do anything special:
-
-```cpp
-auto screen = ScreenInteractive::Fullscreen();
-// screen.HandlePipedInput(true); // This is enabled by default
-screen.Loop(component);
-```
-
-
-## Turning Off Piped Input
-
-If you don't need this feature, or if it conflicts with your custom input handling, you can turn it off.
-
-To disable it, call `HandlePipedInput(false)` before starting your application's main loop:
-
-```cpp
-auto screen = ScreenInteractive::Fullscreen();
-screen.HandlePipedInput(false); // Turn off piped input handling
-screen.Loop(component);
-```
