# 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

# 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);
```
