A CLI toolkit for **TwinCAT/Beckhoff** development workflows. Format, lint, and convert Structured Text (ST) and TwinCAT XML files.

## Features

- 🎨 **Format ST files** - Consistent indentation and code style for Structured Text
- ✅ **Lint ST files** - Check for syntax issues and naming conventions
- 📄 **Format XML files** - Normalize TwinCAT .TcPOU XML files
- 🔄 **Convert ST ↔ XML** - Bidirectional conversion between formats

## Installation

```bash
pip install tctool
```

For development:

```bash
pip install tctool[dev]
```

## Quick Start

### Format Structured Text Files

```bash
# Check formatting (dry-run)
tctool fmt-st --check --format .

# Format files in-place
tctool fmt-st --format --inplace .

# Format a single file
tctool fmt-st --format --inplace ./src/FB_Controller.st
```

### Lint Structured Text Files

```bash
# Check syntax and naming conventions
tctool fmt-st --check .
```

### Format TwinCAT XML Files

```bash
# Check XML formatting
tctool fmt-xml --check ./TcPOU/src

# Format XML files
tctool fmt-xml ./TcPOU/src
```

### Convert Between Formats

```bash
# Convert ST to TwinCAT XML
tctool st2xml ./src ./TcPOU/output

# Convert ST to XML, ignoring certain folders
tctool st2xml ./src ./TcPOU/output --ignore Tests Documentation

# Convert TwinCAT XML to ST
tctool xml2st ./TcPOU/src ./st_export
```
