3 Express

If you want to see the each step of read or write a qr code, can set #:express? to true.

Default will create folder .read.express for qr-read or .write.express for qr-write.

You can use #:express_path to specify another folder name.

Warning: express will generate a set of scribble files, it’s very slow, debug usage only.

Then into the express folder,

scribble --htmls report.scrbl

to generate a detail report.
