Dynamic string validation using go's text/template package

Imagine you could validate the following string:

id: "d416e1b0-97b2-4a49-8ad5-2e6b2b46eae0"
static-string: "abc"
invalid-string: def
random-number: 150

Using go template syntax like this:

id: "{{isUUID}}"
static-string: "abc"
invalid-string: def
random-number: {{inRange 100 200}}

Well, that would be cool wouldn't it? Unfortunately this isn't supported by go's text/template package.

I've built a library which uses a subset of the template syntax to cover this specific use-case: github.com/sleeyax/templatex-go. Check it out for a more detailed example!
