Functions for Generating HTML markup.

This library allows the creation of 'safe' HTML using via code.

Examples:

local html = require "cp.web.html"
print html.p "Hello world!"                                -- "<p>Hello world!</p>"
print html.p { class = "custom" } "Hello world!"        -- "<p class='custom'>Hello world!</p>"
print html.p { class = "custom" } (
    html.b "Bold" .. " and " .. html.i "italic" .. "."
)
-- "<p class='custom'><b>Bold</b> and <i>italic</i>.</p>"
print html("1 < 2")                                        -- "1 &lt; 2" (escaped)
print html("1 < 2", true)                                -- "1 < 2" (unescaped)
print html.p ("<b>bold</b>", true)                        -- "<p><b>bold</b></p>"

Be aware that concatonating with ".." can behave unexpectedly in some cases. For example:

local name = "world!"
print html.p "Hello " .. name                    -- "<p>Hello </p>world!"

The "Hello" gets inserted into the p tag, but the name gets concatonated after the closing tag. To get the name inside the p tag, we need to put brackets around the content:

print html.p ("Hello " .. name)                    -- "<p>Hello world!</p>"

Any tag name can be generated, along with any attribute. The results are correctly escaped. There are two 'special' tag names:

  • CDATA - will generate a &lt;![CDATA[ ... ]]&gt; section with the content contained.
  • __ - (double underscore) will generate a &lt!-- ... --&gt comment block.
