Possibility to allow rendering of HTML comments for E-Mail support

[danielhaake]

I use MJML to generate e-mails in HTML format. MJML can be used to generate HTML output that can be used for various browsers and e-mail clients. Also for Outlook under Windows, which otherwise causes many problems. Among other things, MJML generates HTML comments, so that Outlook, for example, knows that it has to display the HTML differently.

Example of an MJML file:

The generated HTML output including the required HTML comments:

JTE does not render comments. This is a problem for this use case. Because the comments are required. If the comments were also rendered, the JTE syntax could be incorporated using and, for example, sections could be repeated based on the transferred data.

It would therefore be very desirable for the use case if it were possible to set that HTML comments should be rendered as well. Could this be implemented?

Hi, MJML looks pretty cool, will have a look at this!

You can preserve comments by setting this to true:
gg.jte.TemplateEngine#setHtmlCommentsPreserved

If you use Maven or Gradle to precompile templates, you would need to set this there as well.

That sounds great! I'll give it a try.

Can you include this information in the documentation (or did I missed it)? It could certainly be of interest to others too.
