A First ProgramΒΆ

A guide to a programming language would be incomplete without at least one complete program and since Wasabi is intimately tied to generating web pages here’s a Wasabi program for generating a simple HTML page:

<%
<WebEntryPoint("example.asp")> _
Sub Example()
  %>
  <!DOCTYPE html>
  <html>
    <head>
      <title>An Example Wasabi Program</title>
      <meta charset="utf-8">
    </head>
    <body>
      <h1>An Example Wasabi Program</h1>
      <p>Arithmetic: 1 + 1 = <%= 1 + 1 %></p>
      <p>Dynamic Content: x + y = <%= IntRequest("x") + IntRequest("y") %>
    </body>
  </html>
  <%
End Sub
%>

A couple of interesting things about this program:

  1. The entire thing is enclosed in tie-fighters (<% %>). This is a consequence of it’s classic ASP heritage where each file was assumed to be generating a web page and so FogBugz’s entire Wasabi code base lives inside <% and %> so it’s not dumped directly to the response.
  2. <WebEntryPoint("example.asp")> is an annotation that marks the following subroutine as generating a web page at /example.asp.
  3. [1] combined with [2] result in actual content destined for the response being wrapped in reverse-tie-fighters (%> <%) with dynamic content being injected with <%= %>.
