How to use anguluar i18n in html template with variables?

Question

Is it possible to use variables in an angular template i18n string?

In TypeScript I can use template string, eg:

public welcomeMessage = $localize`:@@test.welcome: Hello ${this.name}:user_name:! How's your day?`;

Can I use something similar in html templates? eg

<p i18n="@@test.welcome">Hello {{name}}:user_name:! How's your day?</p>

Hope you get my point.

I've ran into the same issue and the Angular i18n documentation is somewhat unclear about interpolation and naming the interpolated placeholder. For simple text interpolation you can just use:

<p i18n>Hello {{name}}! How's your day?</p>

But AFAIK there is currently no way of naming the interpolated placeholder, it will just end up being the interpolated text:

<source>Hello <x id="INTERPOLATION" equiv-text="{{name}}"/>! How&apos;s your day?</source>

However, you could always change the placeholder (equiv-text) manually in the extracted XLIFF file.
