# Elementary Row Operation Verifier

A CLI tool to verify the correctness of elementary row and column operations on matrices.

## Installation

```sh
cargo install elementary-row-operation-verifier
```

## Usage

```sh
# Single file (opens TUI on errors)
elementary-row-operation-verifier file.lore

# Plain text output
elementary-row-operation-verifier -p file.lore

# Verbose plain text
elementary-row-operation-verifier -v -p file.lore

# Check all .lore files in a directory
elementary-row-operation-verifier check folder/

# Check with verbose output
elementary-row-operation-verifier -v check folder/
```

## TUI Keys

| Key | Action |
|-----|--------|
| `j` / `↓` | Scroll down |
| `k` / `↑` | Scroll up |
| `←` / `→` | Horizontal scroll |
| `Enter` | Toggle detail panel |
| `Esc` | Close detail panel |
| `h` | Toggle help |
| `q` | Quit |

### Coloring

- **Green** — step computed correctly
- **Red bold** — step computed incorrectly (mismatched cells)
- **Blue** — row/column referenced (read) by an operation

## Quick Start

Create a `.lore` file:

```
>   >   >   |
1   2   3
4   5   6
7   8   9

>   >   >   |
2   4   6   x 2
4   5   6
7   8   9
```

Run:

```sh
elementary-row-operation-verifier myfile.lore
```
