Engrave is a generates QR codes for the URLs of your Pelican posts and pages.

This plugin can be installed via:

pip install lm-pelican-engrave

As long as you have not explicitly added a PLUGINS setting to your Pelican settings file, then the newly-installed plugin should be automatically detected and enabled. Otherwise, you must add engrave to your existing PLUGINS list. For more information, please see the How to Use Plugins documentation.

Engrave automatically generates QR codes for all articles and pages in your Pelican site. These QR codes are saved as SVG images in the engrave/ directory within the OUTPUT_PATH defined in your Pelican settings.

The generated QR code is available in the context of the content as content.engrave_qrcode. You can embed the QR code in your templates using the following syntax:

<img src="{{ content.engrave_qrcode }}">

Before generating new QR codes, Engrave clears the engrave/ directory to ensure that no legacy QR codes remain. This aims at maintaining security and consistency. Only by latest codes are available this way.

Engrave validates URL schemas to ensure security. By default, it only allows URLs with the https schema. If your site uses another schema (e.g., http or even ftp), you should add it to the allowed schemas in your Pelican settings.

To specify allowed URL schemas for QR code generation, use the ENGRAVE_ALLOWED_SCHEMES setting in your Pelican configuration file (pelicanconf.py). For example:

ENGRAVE_ALLOWED_SCHEMES = ["https", "http"]

• SITEURL: Ensure that SITEURL is set in your Pelican configuration file. This setting is crucial as it forms the basis of the URLs used for QR code generation. Be sure to synchronize ENGRAVE_ALLOWED_SCHEMES with your SITEURL setting to avoid any discrepancies.
