How to validate .tmx files in Python

Python 
def is_tmx(file_path: str) -> bool:
    """Check if file is a valid TMX by magic bytes."""
    signature = bytes([0x3C, 0x74, 0x6D, 0x78])
    with open(file_path, "rb") as f:
        return f.read(4) == signature

How to validate .tmx files in Node.js

Node.js 
function isTMX(buffer: Buffer): boolean {
  const signature = Buffer.from([0x3C, 0x74, 0x6D, 0x78]);
  return buffer.subarray(0, 4).equals(signature);
}

How to validate .tmx files in Go

Go 
func IsTMX(data []byte) bool {
    signature := []byte{0x3C, 0x74, 0x6D, 0x78}
    if len(data) < 4 {
        return false
    }
    return bytes.Equal(data[:4], signature)
}

Frequently Asked Questions

What is a .tmx file?

What are the magic bytes for .tmx files?

The magic bytes for TMX files are 3C 74 6D 78 at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.

How do I validate a .tmx file?

To validate a .tmx file, read the first bytes of the file and compare them against the known magic bytes (3C 74 6D 78) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.

What is the MIME type for .tmx files?

The primary MIME type for .tmx files is application/x-tmx.
