Do yourself a favor and import the module as from htmlgen import nil and then fully qualify the macros.

Note: The Karax project (nimble install karax) has a better way to achieve the same, see https://github.com/pragmagic/karax/blob/master/tests/nativehtmlgen.nim for an example.

This module implements a simple XML and HTML code generator. Each commonly used HTML tag has a corresponding macro that generates a string with its HTML representation.

MathML

MathML is supported, MathML is part of HTML5. MathML is an Standard ISO/IEC 40314 from year 2015. MathML allows you to draw advanced math on the web, visually similar to Latex math.

Examples

var nim = "Nim"
echo h1(a(href="https://nim-lang.org", nim))

Writes the string:

<h1><a href="https://nim-lang.org">Nim</a></h1>

Example:

let nim = "Nim"
assert h1(a(href = "https://nim-lang.org", nim)) ==
  """<h1><a href="https://nim-lang.org">Nim</a></h1>"""
assert form(action = "test", `accept-charset` = "Content-Type") ==
  """<form action="test" accept-charset="Content-Type"></form>"""


assert math(
  semantics(
    mrow(
      msup(
        mi("x"),
        mn("42")
      )
    )
  )
) == "<math><semantics><mrow><msup><mi>x</mi><mn>42</mn></msup></mrow></semantics></math>"

assert math(
  semantics(
    annotation(encoding = "application/x-tex", title = "Latex on Web", r"x^{2} + y")
  )
) == """<math><semantics><annotation encoding="application/x-tex" title="Latex on Web">x^{2} + y</annotation></semantics></math>"""
