I like the idea. If I recall correctly something similar was suggested recently. E.g. use the ".html" extension to edit an html template and still use a "classic" HTML editor.


Not sure how to handle the parameters for such templates.

In addition (or alternatively) I could imagine to extend ST4 with an "include" function. E.g.

main(firstName, lastName, age="unknown") ::= <<
<includeFile("sample.html")>
>>

The "sample.html" is a plain file (with any extension) and the parser will textually include it.
