The message expression is one that would be really handy.
I will have a look on how we can implement it
How would we do a .substring now?
I think you can do a .substring on any string now as both Java and JavaScript both call that method "substring". I haven't tried it with that method in particular, but being able to do method calls on objects is already possible.
alright!
Hi, I have a problem
let templateEngine = new TemplateEngine({
...STANDARD_CONFIGURATION,
messageResolver: async (key, parameters) => resolveMessage(key, lang, 'defaultMessage')
})
const context = {
user: user
}
templateEngine.processFile(fileName, context)
, it work on tags loike this with #
, but not on variable expressions
<p th:text="#{email.activation.greeting(${user.firstName})}">
Dear
</p>
, this results in - Dear{0}
The templates I have worked fine with spring thymeleaf
Did I forget something ?
