# ![](themes/dark/icons/32.png) LibreQR

[Lire ceci en français](README_fr.md)

A PHP Web interface for generating QR codes.

## Demo

A LibreQR instance is available at <https://qr.antopie.org>.

## Installation

### Generic

Just place this source code in a Web server with PHP.

`wget https://code.antopie.org/miraty/libreqr/archive/1.3.0.zip`

GD extension is required.

`apt install php7.3-gd`

LibreQR need writing rights on the `css/` directory.

```
chown -R www-data:www-data /var/www/libreqr/css
chmod -R 600 /var/www/libreqr/css
```

### YunoHost

There is [a package](https://code.antopie.org/miraty/qr_ynh/) for [YunoHost](https://yunohost.org/).

For historical reasons, LibreQR is technically named `qr` in YunoHost.

You can install it from the WebAdmin or with this command :

```
sudo yunohost app install qr
```

## Themes

### Change theme

In config.inc.php, set $theme to the wanted theme.

By default, 3 themes are offered:

* dark, the default dark theme. Used here: <https://qr.antopie.org>
* light, the light theme.
* parinux, a blue theme, made for [Bastet](https://bastet.parinux.org), the [Parinux](https://parinux.org)'s CHATON. Used here: <https://codeqr.parinux.org>

### Make a theme

* Copy themes/dark to themes/[new theme's name]
* Fill theme.php according to CSS colors you want
* Change the source.png image according to your theme
* To automatically generate favicons with the rights sizes, use `php themes/resize.php [theme's name]`

This last step will need [ImageMagick](https://imagemagick.org) and [pngquant](https://pngquant.org) to be installed.

```apt install imagemagick pngquant```
