Elixir/Erlang bindings for htacg's tidy-html5

The granddaddy of HTML tools, with support for modern standards http://www.html-tidy.org

• tidy-html5

The binding is implemented as a C-Node following the excellent example in Overbryd's package nodex. If you want to learn how to set up bindings to C/C++, you should definitely check it out.

• nodex
  • distributed Elixir
  • save binding with C-Nodes

C-Nodes are external os-processes that communicate with the Erlang VM through erlang messaging. That way you can implement native code and call into it from Elixir in a safe predictable way. The Erlang VM stays unaffected by crashes of the external process.

Example

For more examples please checkout tests.

test "can parse broken html" do
  result = TidyEx.parse("<div>Hello<span>World")
  assert result == "<div>Hello<span>World</span></div>"
end

test "can clean and repair broken html" do
  result = TidyEx.clean_and_repair("<div>Hello<span>World")
  assert result == "<div>Hello<span>World</span></div>"
end

test "can run diagnostics on invalid html" do
  result = TidyEx.run_diagnostics("<pp>Hello World</p>")
  assert result == "line 1 column 1 - Error: <pp> is not recognized!\nThis document has errors that must be fixed before\nusing HTML Tidy to generate a tidied up version."
end
