Ok, So Deit allows D code inside html... looks great.
But how do external variables work? If I create a variable in
the server(such as a class), can an html file access it easily?
(not having to jump through hoops)
doctype html
html
head
title D string interpolations test
body
- import std.algorithm : min;
p Four items ahead:
- foreach( i; 0 .. 4 )
- auto num = i+1;
p Item #{ num + extvar }
//- Unescaped output
p Prints 8: !{ min(10, 2*6, 8) }
here, extvar is a int located somewhere else(other deit html
file that has ran(hopefully) or vibe.d project that created it.
(Obviously there has to be a way to get extvar)
E.g., If deit can have a special variable called context that
each html file can access and along with the vibe.d project,
then we can easily pass the variable.
doctype html
html
head
title D string interpolations test
body
- import std.algorithm : min;
p Four items ahead:
- foreach( i; 0 .. 4 )
- auto num = i+1;
p Item #{ num + (int)context["extvar"] }
//- Unescaped output
p Prints 8: !{ min(10, 2*6, 8) }
or whatever
I am a very new at this, but I think "the solution" is to call
res.render! with all alias names you need.
Defining int extvar =... before; you use:
res.render!("your-template.dt",extvar,..)
hope this helps. Regards mt.
