Subject: Re: Ruby+Tk+HTML Example

It seems the syntax of Ruby+Tk in Erb is more rigorous
than in Ruby. Here is another snippet that works.
This is a substitute for the inside of if-end statement
in the previous example.

<%message = TkVariable.new%>
<%"padx 20; pady 20"%>
<%TkLabel.new {%>
    <%text 'Enter a message:'%>
    <%pack {ph}%>
<%}%>
<%entry = TkEntry.new{%>
    <%textvariable message%>
<%}%>
<%entry.pack{ ph }%>
<%TkButton.new {%>
    <%text content%>
    <% command proc {p "Thank you"; exit}%>
    <%pack { ph }%>
<%}%>
<%TkButton.new {%>
    <%text 'Exit'%>
    <% command proc {p message.value; exit}%>
    <% pack { ph }%>
<%}%>

<%Tk.mainloop%>
