+# simple HTML DSL for lua 5.3
+
+this library returns a table which, when indexed with the name of an HTML tag, provides a function which generates a data structure representing an HTML element. when this data structure is converted to a string, the corresponding HTML is generated.
+
+ local h = require "html"
+
+calling a tag's function with no arguments produces a self-closing tag.
+
+### source
+ print(h.hr())
+### output
+ <hr />
+
+calling a tag's function with a single array or value argument produces a tag with the children provided in the array. non-table values may appear in the list of children or in its stead. they are converted to a string an escaped.
+
+### source
+ print(h.section{h.h1"foo",h.p"bar"})
+### output
+ <section><h1>foo</h1><p>bar</p></section>
+
+calling a tag's function with a single set of key/value pairs as the argument produces a self-closing tag with attributes corresponding to the key/value pairs
+
+### source
+ print(h.meta{charset = "utf-8"})
+### output
+ <meta charset="utf-8" />
+
+calling a tag's function with a set of key/value pairs and then an array or value as the arguments produces a tag with attributes corresponding to the key/value pairs.
+
+### source
+ print(h.a({href = "https://example.com"}, "foobar"))
+### output
+ <a href="https://example.com">foobar</a>
+
+a table used in a list of children must either be generated from the HTML functions or have a `tohtml` function or a `render` function, returning HTML structures or HTML source respectively. a table that is not a set of attributes or an array of element children may not be used as arguments to an HTML function.
+
+### source
+ local db_record = {name = "foobar", id = 256}
+ setmetatable(db_record, {
+ tohtml = function(x)
+ return h.a(
+ {href = "https://example.com/" .. x.id}, x.name)
+ end
+ })
+
+ print(h.p{"search result: ", db_record})
+### output
+ <p>search result: <a href="https://example.com/256">foobar</a></p>
+
+the `raw` function will insert text verbatim into the HTML, unescaped.
+
+### source
+ local html_source = "<marquee>hello</marquee>"
+ print(h.p{html_source})
+ print(h.p{h.raw(html_source)})
+### output
+ <p>&lt;marquee&gt;hello&lt;/marquee&gt;</p>
+ <p><marquee>hello</marquee></p>
+
+included with this documentation is `example.lua` which produces this documenation in HTML via the DSL.
