This projects implements Data Matrix barcode in the Fusion programming language. Fusion can be automatically translated to pure C, C++, C#, D, Java, JavaScript, Python, Swift, TypeScript and OpenCL with no additional dependencies.

Currently the project includes an encoder for all ECC 200 symbol sizes (square and rectangular). Symbol size may be set a priori or a smallest symbol may be selected for the encoded message. ASCII encoding and digit pairs are supported. I made an attempt to support ISO 8859-1, but I'm not sure whether it's correct.

Future version will support other encodings and perhaps a decoder.

Try the HTML 5 encoder right in your browser. Other sample programs print the barcodes in the terminal, as hashes and spaces.
