[FEATURE] support regex for templating

[JoernBerkefeld]

Would require 2 values per templating variable: search (regex) and replace (string/number/boolean).

Would allow finding strings with optional variable spacing or line breaks.

Hi, will it be possible to support exact value matching? For example, matching only when values is exactly "Name" (e.g. via ^Name$, without affecting cases where Name appers as part of a longer string.

Currently, it's possible to match "Name" using \"Name\", but this breaks the JSON

[JoernBerkefeld]

Good question. Can you give me a few json examples?

In my case, I have senderProfile named Dynamic which need to map. The word Dynamic is very common and it appers in many contexts (asset names, other sender profiles, sender classification) so partial matching isn't sufficient

For example:
senderProfile

"CustomerKey": "Dynamic",
"Name": "Dynamic Sender Profile",

journey

"r__sendClassification_key": "Dynamic Transactional",
"r__senderProfile_key": "Dynamic",

asset

"fileProperties": {
  "fileName": "OrderConfirmationDynamic_DEV"
},
"name": "OrderConfirmationDynamic_DEV",

referece in asset

ContentBlockbyKey("DynamicEmailAddress_DEV")

I only want to match the exact value "Dynamic" (e.g. using something like ^Dynamic$ or \bDynamic\b) and avoid matching where it is just part of longer string

I think this will be the answer:

var str = 'asd-0.testing';
var regex = /(asd-)\d(\.\w+)/;
