Build

Mac OS

git clone https://github.com/lbeder/qrcode-cli
cd qrcode-cli

cargo build --release

To get stuff working later, use the nightly branch of Rust:

rustup override set nightly

Install a standard Linux target on a Mac (note, that the opposite is currently impossible):

rustup target add x86_64-unknown-linux-musl

Use homebrew to download a community-provided binary for musl cross-compilation:

brew install FiloSottile/musl-cross/musl-cross

Now you can build it:

CROSS_COMPILE=x86_64-linux-musl cargo build --target=x86_64-unknown-linux-musl

Test

cargo test --release

Example

Let's see few QR code generation examples:

To encode Hello World using the L (up to ~7% damage):

./target/release/qrcode-cli -o images/example1.svg -e L "Hello World"

To encode Hello World using the H (up to ~30% damage) with the embedding of the original data:

./target/release/qrcode-cli -o images/example2.svg -e H -t "Hello World"

To encode a long message Hello World using the H (up to ~30% damage) with the embedding of the original data:

./target/release/qrcode-cli -o images/example3.svg -e H -t "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur.

To encode Hello World and render the QR code image in a different color:

./target/release/qrcode-cli -o images/example4.svg -c "#FF0000" "Hello World"
