!!! warning Automations are currently in a beta stage. They work pretty stable but if I encounter any issues while working on them, I might change how they work breaking existing automations. I will try to avoid this and am pretty confident it won't happen.

Automations allow Tandoor to automatically perform certain tasks, especially when importing recipes, that would otherwise have to be done manually. Currently, the following automations are supported.

Unit, Food, Keyword Alias

Foods, Units and Keywords can have automations that automatically replace them with another object to allow aliasing them.

This helps to add consistency to the naming of objects, for example to always use the singular form for the main name if a plural form is configured.

These automations are best created by dragging and dropping Foods, Units or Keywords in their respective views and creating the automation there.

You can also create them manually by setting the following

• Parameter 1: name of food/unit/keyword to match
• Parameter 2: name of food/unit/keyword to replace matched food with

These rules are processed whenever you are importing recipes from websites or other apps and when using the simple ingredient input (shopping, recipe editor, ...).

Description Replace

This automation is a bit more complicated than the alis rules. It is run when importing a recipe from a website.

It uses Regular Expressions (RegEx) to determine if a description should be altered, what exactly to remove and what to replace it with.

• Parameter 1: pattern of which sites to match (e.g. .*.chefkoch.de.*, .*)
• Parameter 2: pattern of what to replace (e.g. .*)
• Parameter 3: value to replace matched occurrence of parameter 2 with. Only one occurrence of the pattern is replaced.

To replace the description the python re.sub function is used like this re.sub(<parameter 2>, <parameter 2>, <descriotion>, count=1)

To test out your patterns and learn about RegEx you can use regexr.com

!!! info In order to prevent denial of service attacks on the RegEx engine the number of replace automations and the length of the inputs that are processed are limited. Those limits should never be reached during normal usage.

Instruction Replace

This works just like the Description Replace automation but runs against all instruction texts in all steps of a recipe during import.

Also instead of just replacing a single occurrence of the matched pattern it will replace all.

Order

If the Automation type allows for more than one rule to be executed (for example description replace) the rules are processed in ascending order (ordered by the order property of the automation). The default order is always 1000 to make it easier to add automations before and after other automations.

Example:

1. Rule ABC (order 1000) replaces everything with abc
2. Rule DEF (order 2000) replaces everything with def
3. Rule XYZ (order 500) replaces everything with xyz

After processing rules XYZ, then ABC and then DEF the description will have the value def
