The midstr CLI tool is a simple Rust application that allows you to center a given text within a specified total length by adding padding characters on both sides. This can be useful for formatting text in various contexts.

midstr is part of my Rust Learning Series, where I explore Rust programming concepts and try to build various different tools and applications along the way.

Usage

To use midstr, follow the instructions below:

Prerequisites

• Rust must be installed on your system.

Installation

Clone this repository to your local machine:

git clone https://github.com/your-username/midstr.git

Navigate to he project:

cd midstr

Build the application using Cargo:

cargo build --release

Running the Application

To center a text within a specified total length, use the following command format:

./target/release/midstr <total_length> <name> [fill_char]

• <total_length>: The total length of the resulting centered text.
• <name>: The text that you want to center.
• [fill_char] (optional): The character used for padding. Defaults to '-' if not provided.

Example

./target/release/midstr 15 Hello *

This will produce the following output:

*** Hello ***

Error Handling

• If the number of arguments is incorrect, the application will display a usage message and exit.
• If the <total_length> argument is not a positive integer, an error message will be displayed.
