This is a generic CLI app example using crossterm to provide both pipeline input as well as an interactive interface

Crossterm Piping and Interactive Input Example

This example demonstrates how to use Rust and crossterm to accept both piped stdin input and interactive terminal input in a single CLI app. Given the scarcity of examples on piping into crossterm, I created this to provide an example for anyone trying to do the same.

the key to using using piped inputs is to use the use-dev-tty feature of crossterm. This allows you to use the input() function to read from stdin. Without this feature, the input() function will not work with piped input.

Features

• Piped stdin Input: Accept input directly from another command using pipes.
• Interactive Terminal Input: Type and interact directly within the terminal.
• Colored UI: Different colors for prompts, user input, and system responses for clarity.
• Command Handling: Recognizes exit and quit commands for easy termination.
• Keyboard Support: Use CTRL+C to exit and the backspace key for text corrections.

Usage

1. Clone the Repository:

   git clone https://github.com/cosmikwolf/terminal-input-interface.git
   cd terminal-input-interface

2. Run the Application:

   cargo run

3. Experience Piped Input:

   echo "Sample piped input" | cargo run

Dependencies

• crossterm: Used for creating the terminal interface.
