# LazyDiff
A terminal-based diff viewer written in Rust that makes it easier to compare
files. The tool not only shows you nicely formatted diffs, it allows you to
copy the patch content to the clipboard or export it as a file.
## Getting Started
### Installation
You can install lazydiff using Cargo:
```bash
cargo install lazydiff
```
### Prerequisites
- Rust 1.70 or higher
- A terminal emulator with support for modern terminal features
### Building from Source
If you prefer to build from source:
```bash
git clone https://github.com/yourusername/lazydiff.git
cd lazydiff
cargo build --release
```
The binary will be available at `target/release/lazydiff`.
## Usage
### Basic Usage
Launch lazydiff with two files to compare:
```bash
lazydiff file1.txt file2.txt
```
Or start lazydiff and interactively select files:
```bash
lazydiff
```
You can also specify just the source file:
```bash
lazydiff source.txt
```
