By the way, the following wrapper function can be used to get an interface that is similar to the Diet render!() function:
static import embd;
void renderEmbd(string FILE, ALIASES...)(OutputStream dst)
{
mixin(vibe.templ.utils.localAliases!(0, ALIASES));
class Context : embd.Context {
OutputStream output__;
mixin(renderer);
void write(string content, dchar eval_code)
{
if (eval_code == '=')
filterHtmlEscape(output__, content);
else
output__.write(content, false);
}
}
scope Context ctx = new Context;
ctx.output__ = dst;
ctx.render!(import(FILE), `!=`, `<%`, `%>`)();
}
void renderEmbd(string FILE, ALIASES...)(HTTPServerResponse res, string content_type = "text/html; charset=UTF-8")
{
res.contentType = content_type;
renderEmbd!(FILE, ALIASES)(res.bodyWriter);
}
void renderEmbdCompat(string FILE, TYPES_AND_NAMES...)(OutputStream dst, ...)
{
import core.vararg;
import std.variant;
mixin(localAliasesCompat!(0, TYPES_AND_NAMES));
class Context : embd.Context {
OutputStream output__;
mixin(renderer);
void write(string content, dchar eval_code)
{
if (eval_code == '=')
filterHtmlEscape(output__, content);
else
output__.write(content, false);
}
}
scope Context ctx = new Context;
ctx.output__ = dst;
ctx.render!(import(FILE), `!=`, `<%`, `%>`)();
}
Example usage:
string caption = "Hello, World!";
//res.renderEmbd!("test.embd", caption, req)();
res.bodyWriter.renderEmbdCompat!("test.embd",
string, "caption",
HTTPServerRequest, "req")(caption, req);
The non-compat version may suffer from a memory corruption bug in DMD, so I would avoid it for now. I'll prepare a pull request to see if Nathan is willing to include them.
