<h1 align="center" style="color:navy">Hello from PSP!</h1>

<%-- This image is served by WebKit --%>
<p align="center"><img src="psplogo.png" alt="Python Server Pages"></p>

<h4 align="center">This is the sample/test page<br>
for an implementation of<br>
<span style="color:navy">Python Server Pages</span>.</h4>

<p align="center">Read the <a href="PSPDocs.psp"><strong>PSP documentation</strong></a>.
See the <a href="View.py?filename=<%=os.path.basename(self.request().serverSidePath())%>"><strong>source for this page</strong></a>.</p>

<p>The syntax for Python Server Pages is almost identical to that of Java Server Pages (JSP).  Just the scripting language is different! And obviously better.  In fact, just about anything you can do with JSP, you can do with PSP, and more.  With PSP, not only can you create template text that will be inerted in one method when the page is run as a servlet, but you can choose which base class to inherit from, you can choose which method of the base class to over-ride with your template text, and you can add additional methods to the servlet class, all from the PSP template code.</p>

<hr>

<p>The text below comes from another psp page which was inserted into this one with the <tt>&lt;%@&nbsp;include&nbsp;%&gt;</tt> directive.</p>

<div style="color:red"><%@ include file="my_include.psp" %></div>

<p>There are actually two ways to insert the contents of another file into a PSP page:</p>

<p>If you use <tt>&lt;%@&nbsp;include&nbsp;file="somefile"&nbsp;%&gt;</tt>, it will effectively insert the contents of the other file before class creation time.</p>

<p>Using <tt>&lt;psp:include&nbsp;path="somefile"&gt;</tt> will insert the output of the specified WebKit URL into the page <em>dynamically</em>.</p>

<div style="color:red"><psp:insert file="APSPinclude.html"></div>

<p>Time at which dynamic output was generated:</p>
<psp:include path = "APSPinclude.psp">

<h4>Below is a loop test:</h4>

<p>Loops are the trickiest part of PSP due to Python indentation for blocks syntax.</p>

<ul><% for i in range(2): %><%-- loop #1, an automatic loop --%>
<% self.write('<li>Outer loop: '); self.write(i+1) %>
<ul><% for j in range(2): %><%-- loop #2, another automatic loop --%>
<li>Inner loop: <%= j+1 %>
<% self.write('(still in the inner loop)') %></li>
<% end %></ul></li><%-- end loop #2 --%>
<% end %></ul><%-- end loop #1 --%>

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
