I hope some of you find it useful!

Great, finally something that works for plain text files!
I guess a simple wrapper could make it work with a similar interface to
vibe.d's Diet templates (slightly ugly with that struct because of the
additional range template argument and not tested at all):
struct renderEmbd(string FILE, ALIASES...)
{
class Context(R) : emdb.Context {
R* _output;
mixin(renderer);
void write(string content, dchar evalCode){
if (evalCode == '=')
filterHtmlEscape(*_output, content);
else
_output.put(content);
}
}
static void opCall(R)(ref R output_range)
{
static Context!R ctx;
if( !ctx ) ctx = new Context!R;
ctx._output = output_range;
scope(exit) ctx._output = null;
ctx.render!(import(FILE), `!=`, `%`, `%`)();
}
}
Usage:
auto dst = appender!string();
renderEmbd!(userprofile.embd.html, username, title, biography)(dst);

Yes, my original intent was to use it in vibe.d projects.
Should I try to adopt it into vibe.d?

Actually I plan to start breaking up the vibe-d package into smaller
functional blocks at some point and the Diet template compiler might
also end up as a separate package, as it also really is a quite generic
module. I think an output range based interface would be great to have,
though.
One interesting option would be to add some *optional* vibe.d support. A
version(Have_vibe_d){} block could be used to e.g. add a UFCS based
possibility to directly render to a HttpServerResponse, similar to the
res.render!() Diet render function. DUB automatically defines Have_*
version identifiers for all packages that are used for the current
project, so this would then automatically be available for vibe.d based
projects without introducing a hard dependency.
