# QRCode Terminal
|
|
|
|
[](https://travis-ci.org/mdp/qrterminal)
|
|
|
|
A golang library for generating QR codes in the terminal.
|
|
|
|
Originally this was a port of the [NodeJS version](https://github.com/gtanner/qrcode-terminal). Recently it's been updated to allow for smaller code generation using ASCII 'half blocks'
|
|
|
|
## Example
|
|
Full size ASCII block QR Code:

|
|
|
|
Smaller 'half blocks' in the terminal:

|
|
|
|
## Install
|
|
|
|
`go get github.com/mdp/qrterminal`
|
|
|
|
## Usage
|
|
|
|
```go
|
|
import (
|
|
"github.com/mdp/qrterminal"
|
|
"os"
|
|
)
|
|
|
|
func main() {
|
|
// Generate a 'dense' qrcode with the 'Low' level error correction and write it to Stdout
|
|
qrterminal.Generate("https://github.com/mdp/qrterminal", qrterminal.L, os.Stdout)
|
|
}
|
|
```
|
|
|
|
### More complicated
|
|
|
|
Large Inverted barcode with medium redundancy and a 1 pixel border
|
|
```go
|
|
import (
|
|
"github.com/mdp/qrterminal"
|
|
"os"
|
|
)
|
|
|
|
func main() {
|
|
config := qrterminal.Config{
|
|
Level: qrterminal.M,
|
|
Writer: os.Stdout,
|
|
BlackChar: qrterminal.WHITE,
|
|
WhiteChar: qrterminal.BLACK,
|
|
QuietZone: 1,
|
|
}
|
|
qrterminal.GenerateWithConfig("https://github.com/mdp/qrterminal", config)
|
|
}
|
|
```
|
|
|
|
HalfBlock barcode with medium redundancy
|
|
```go
|
|
import (
|
|
"github.com/mdp/qrterminal"
|
|
"os"
|
|
)
|
|
|
|
func main() {
|
|
config := qrterminal.Config{
|
|
HalfBlocks: true,
|
|
Level: qrterminal.M,
|
|
Writer: os.Stdout,
|
|
}
|
|
qrterminal.Generate("https://github.com/mdp/qrterminal", config)
|
|
}
|
|
```
