nimforum mirror - html tags from template not being rendered

Col (orginal) [2021-08-17T01:11:22+02:00] view original

I am trying to render html output via templates but the html tags are being displayed as tags. I'm sure (hope) that I am just missing something obvious here. Here's a small complete sample which replicates the problem.

main.nim

import asyncdispatch, jester
import templ8

routes:
  get "/":
    resp renderHello(renderName("World"))

runForever()

templ8.nim

#? stdtmpl(subsChar = '$', metaChar = '#', toString = "xmltree.escape")
#import xmltree
#
#proc renderName*(name: string): string =
#  result = ""
<b>${name}</b>
#end proc
#
#proc renderHello*(nameHtml: string): string=
<!DOCTYPE html>
<html lang="en">
 Hello ${nameHtml}
</html>
#end proc

When I run this in the browser I get: Hello <b>World</b>

Thanks for any advice

Found the problem (obvious now :). I have to remove the

, toString = "xmltree.escape"

from the filter definition. Just for clarity the template file filter now looks like:

#? stdtmpl(subsChar = '$', metaChar = '#')

You could also have a look at nimja templates, they work quite similar, but look more like jinja or twig. https://github.com/enthus1ast/nimja
