static

adds a template function to a template Program object

Example:
  string qhtml = "<form id=\"upload_form\" enctype=\"multipart/form-data\" method=\"post\" action=\"{{ $URL_PREFIX }}upload-file">
  <fieldset class=\"workflow_list\">
  <legend>Step 1: Select Workflow</legend>
  <select class=\"worfklows\" name=\"workflow\" id=\"workflow\">
  {% foreach my hash<auto> $h ($ctx.workflows.pairIterator()) { %}
  <option value="{{ $h.key }}">{{ $h.value.label }}</option>
  {% } %}
  </select>
  </fieldset>
  </form>";
  StaticTextTemplateBase::add(p, "/html/index.qhtml", qhtml, "t0");

Parameters

  p | the Program object to add the template function to
  fn | the name of the template function
  name | the name of the template

  src

  the source of the template; Qore source code is delimited as follows:
  - expressions: Qore expressions are delimited by double curly brackets: `{{ }}`; such expressions are expected to return a string value that will be inserted directly into the text generated by the template
  - statements: Qore statements are delimited by a curly bracket and percent sign: `{% %}`; these statements can be any Qore code legal for the template Program object; for example loop constructs are often used (see the example above)

The ctx hash variable is always present in the template code; this is the call context variable, and is set to the same value as the cx argument in HttpServer::AbstractHttpRequestHandler::handleRequest() plus any context added by the actual handler handing the request. In the example above, a `"workflows"` key assigned to a hash has been added to the call context variable.

Returns
  the source code of the generated template (without Program overhead)
