Hi Hans (et al.),at the ConTeXt meeting I learned that ConTeXt has not only built-in QR codes but also the common barcode types EAN 13 and Code128.
The ean13 version can also handle ean13+5 (ISBN + price) and ean13+2.
"""
\input meta-imp-barcodes.mkxl
\definefont[EANfont][OCRAStd at 10bp]
\starttext
\barcode[] % default example code128
\barcode[code=ean13,text={978396543604}] % ok
\barcode[code=ean13,text={9783965436046-03995}] % ISBN not ok
\qrcode[text={https://fiee.net},color=orange,width=2cm]
\stoptext
"""
Is the "input" line the right way? \usemodule[barcodes] doesn’t work.
The ean13 version can’t cope with complete numbers but insists on
calculating the checksum itself. That’s a bit cumbersome since I usually
have my complete ISBN in a variable.
There’s a spurious ">" after the EAN. Hraban
