Debugging

You can run Eleventy build in debug mode to get informations and warnings about your Markdown, HTML or plugin options.

Add DEBUG=* in front of the command to get messages in the console, including a lot of debug message from Eleventy, not specific to this plugin.

Use DEBUG=image-responsiver:* to only get debug messages from the plugin:

images-responsiver:info Transforming my-logo.png +0ms
images-responsiver:warning The image should have a width attribute: my-logo.png +0ms
images-responsiver:info Transforming colorful-netherlands.jpg +2ms
images-responsiver:warning The image should have a width attribute: colorful-netherlands.jpg +1ms

images-responsiver (on which this plugin is based) uses the great debug module to provide these debug messages.

You can use different values for DEBUG=:

DEBUG=*	get all messages, even from Eleventy and other packages
DEBUG=images-responsiver:*	get all messages, only from images-responsiver
DEBUG=images-responsiver:info	get only information messages from images-responsiver
DEBUG=images-responsiver:warning	get only warning messages from images-responsiver
DEBUG=images-responsiver:error	get only error messages from images-responsiver
DEBUG=images-responsiver:error,images-responsiver:warning or DEBUG=images-responsiver:*,-images-responsiver:info	get only warning and error messages from images-responsiver
