+ and there are some good resources available on the web that will
+ get you up to speed quickly. Go to the
+ <a class="link" href="help.html#websites" title="Web Sites">web sites</a> section and have a look.
+ </p><div class="example"><a name="hello_world"></a><p class="title"><b>Example 1. Hello World</b></p><div class="example-contents"><p style="width:90%">
+ As with any tool, it's always nice to see something work, so
+ let's create a small "Hello World" page.
+ </p><p style="width:90%">
+ Assuming you have Apache configured correctly, create a file
+ called <code class="filename">hello.rvt</code> where Apache can find
+ it, with the following content:
+ </p><pre class="programlisting"><?
+puts "Hello World"
+?>
+
+</pre><p style="width:90%">
+ If you then access it with your browser, you should see a
+ blank page with the text "Hello World" (without the quotes) on it.
+ The command <span style="font-family:monospace"><span class="command"><strong>puts</strong></span></span> is the good old Tcl command for
+ terminal printing, which appends to the argument string the control
+ characters needed to open a newline. When you don't have to run through
+ complex elaboration and the output can be lumped
+ in a single string (just like in the 'Hello World' example) you
+ can draw on the popular shorthand syntax for string
+ output that comes handy in many cases
+ </p><pre class="programlisting"><?= "Hello World" ?>
+</pre><p style="width:90%">

+ </p><pre class="programlisting">puts -nonewline "Hello World"</pre><p style="width:90%">

+

+ We can use this Rivet script to get the variable values:

+
+</pre><p style="width:90%">
+ The first statement checks to make sure that the
+ <code class="varname">boss</code> variable has been passed to the
+ script, and then does something with that information. If
+ it's not present, an error is added to the list of errors.
+ </p><p style="width:90%">
+ In the second block of code, the variable
+ <code class="varname">salary</code> is fetched, with one more error
+ check - because it's a number, it needs to be composed of
+ digits.
+ </p><p style="width:90%">
+ The <code class="varname">boss</code> variable isn't required to have
+ been sent - we set it to "Mr. Burns" if it isn't among the
+ information we received.
+ </p><p style="width:90%">
+ The last bit of variable handing code is a bit trickier.
+ Because <code class="varname">skills</code> is a listbox, and can
+ potentially have multiple values, we opt to receive them as a
+ list, so that at some point, we could iterate over them.
+ </p><p style="width:90%">
+ The script then checks to make sure that
+ <code class="varname">errlist</code> is empty and outputting a thankyou
+ message. If <code class="varname">errlist</code> is not empty, the list
+ of errors it contains is printed.
+ </p></div></div><br class="example-break"><div class="example"><a name="file_upload"></a><p class="title"><b>Example 4. File Upload</b></p><div class="example-contents"><p style="width:90%">
+ The <span style="font-family:monospace"><span class="command"><strong>::rivet::upload</strong></span></span> command endows Rivet with an
+ interface to access files transferred over http as parts of a
+ multipart form. The following HTML in one file, say,
+ <code class="filename">upload.html</code> creates a form with a text
+ input entry. By clicking the file chooser button the file
+ browser shows up and the user selects the file to be uploaded
+ (the file path will appear in the text input). In order to make
+ sure you're uploading the whole file you must combine the
+ action of the enctype and method attributes of the
+ <form...> tag in the way shown in the example. Failure
+ to do so would result in the client sending only the file's
+ path, rather than the actual contents.
+ </p><pre class="programlisting"><form action="foo.rvt" enctype="multipart/form-data" method="post">
+<input type="file" name="MyUpload"></input>
+<input type="submit" value="Send File"></input>
+</form>
+
+</pre><p style="width:90%">
+ In the script invoked by the form
+ (<code class="filename">upload.rvt</code>) <span style="font-family:monospace"><span class="command"><strong>upload</strong></span></span>
+ ?<span style="font-family:monospace; font-weight: bold;">argument ...</span>? commands can be used to manipulate the
+ various files uploaded.
+ </p><pre class="programlisting"><?
+::rivet::upload save MyUpload /tmp/uploadfiles/file1
+puts "Saved file [::rivet::upload filename MyUpload] \
+ ([::rivet::upload size MyUpload] bytes) to server"
+?>
+
+</pre><p style="width:90%">
+ Don't forget that the apache server must have write access to
+ the directory where files are being created. The Rivet Apache
+ directives have a substantial impact on the upload process,
+ you have to carefully read the docs in order to set the
+ appropriate directives values that would match your
+ requirements.
+ </p><p style="width:90%">
+ It is also important to understand that some
+ <span style="font-family:monospace"><span class="command"><strong>upload</strong></span></span> commands are effective only when
+ used in a mutually exclusive way. Apache stores the data in
+ temporary files which are read by the <span style="font-family:monospace"><span class="command"><strong>upload save
+ ?<span style="font-family:monospace; font-weight: bold;">upload name</span>? ?<span style="font-family:monospace; font-weight: bold;">filename</span>?</strong></span></span> or by the
+ <span style="font-family:monospace"><span class="command"><strong>upload data ?<span style="font-family:monospace; font-weight: bold;">upload name</span>?</strong></span></span>
+ command. Subsequent calls to these 2 commands using the same
+ ?<span style="font-family:monospace; font-weight: bold;">upload name</span>? argument will return no data on the
+ second call. Likewise <span style="font-family:monospace"><span class="command"><strong>upload channel ?<span style="font-family:monospace; font-weight: bold;">upload
+ name</span>?</strong></span></span> will return a Tcl file channel that you
+ can use in regular Tcl scripts only if you haven't already
+ read the data, for example with a call to the <span style="font-family:monospace"><span class="command"><strong>upload
+ data ?<span style="font-family:monospace; font-weight: bold;">upload name</span>?</strong></span></span> command.
+ </p></div></div><br class="example-break"><div class="example"><a name="file_download"></a><p class="title"><b>Example 5. File Download</b></p><div class="example-contents"><p style="width:90%">
+ In general setting up a data file for being sent over http is
+ as easy as determining the file's URI and letting Apache's
+ do all that is needed. If this approach fits your design all
+ you have to do is to keep the downloadable files somewhere
+ within Apache's DocumentRoot (or in any of the directories
+ Apache has right to access).
+ </p><p style="width:90%">
+ When a client sends a request for a file, Apache takes
+ care of determining the filetype, sends appropriate headers to
+ the client and then the file content. The client is responsible
+ for deciding how to handle the data accordingly to the
+ "content-type" headers and its internal design. For example
+ when browsers give up trying to display a certain "content-type"
+ they display a download dialog box asking for directions from
+ the user.
+ </p><p style="width:90%">
+ Rivet can help if you have more sofisticated needs. For
+ instance you may be developing an application that uses
+ webpages to collect input data. This information might be
+ passed on to scripts or programs for processing.
+ In this case a real file representing the
+ data doesn't exist and the content is generated on demand
+ by the server.
+ In other circumstances you may need to dynamically inhibit
+ the download of specific files and hide them away,
+ Your scripts may expunge from the pages
+ every link to these files (your pages are dynamic, aren't
+ they?) and move them out of way, but it looks like a
+ cumbersome solution.
+ </p><p style="width:90%">
+ Putting Tcl and Rivet in charge of the whole download
+ mechanism helps in building cleaner and safer approaches to
+ the download problem.
+ </p><p style="width:90%">
+ In this example a procedure checks for the existence of a
+ parameter passed in by the browser. The parameter is the name
+ (without extension) of a pdf file.
+ Pdf files are stored in a directory whose path is
+ in the <span style="font-family:monospace"><span class="command"><strong>pdf_repository</strong></span></span> variable.
+ </p><p style="width:90%">
+ This code is reported as an example of how to control
+ the protocol using the <span style="font-family:monospace"><span class="command"><strong>headers</strong></span></span> command.
+ </p><pre class="programlisting"># Code example for the transmission of a pdf file.

+ <code class="constant">Content-Description</code> and
+ <code class="constant">Content-Length</code> headers to inform
+ the client about the file type, name and size. Notice that in

+ uses a specialiezed form of the <span style="font-family:monospace"><span class="command"><strong>headers</strong></span></span>

+ The <span style="font-family:monospace"><span class="command"><strong>headers</strong></span></span> command is crucial for generating
+ XML messages that have to be understood by JavaScript code used
+ in Ajax applications.
+ </p><p style="width:90%">
+ Ajax is a web programming technique that heavily relies on the abilty of a web browser to run in backround
+ JavaScript functions. JavaScript functions can be run as callbacks of events generated by a user interaction
+ but they can also react to other I/O events, for example network events.
+ Modern browsers endow JavaScript with the ability to build http GET/POST requests to be sent to a remote
+ webserver. Generally these requests refer to scripts (e.g. Tcl scripts run by Rivet) which inherit as
+ variables the arguments encoded in the request.
+ The output produced by these scripts is sent back to the browser where callbacks functions extract
+ information and hand it down to functions that directly manipulate a page's DOM.
+ Therefore through Ajax becomes possible to build web applications that are more responsive and flexible:
+ instead of going through the cycle of request-generation-transfer-display
+ of a whole page, Ajax scripts request from a webserver only the essential data to be displayed.
+ Ajax emphasizes the requirement of separation between data and user interface, saves
+ the server from sending over the same html code and graphics if only a fraction of a page has to be
+ updated, allows the programmer to design flexible solutions for complex forms and makes possible
+ to find new innovative approaches to simple problems (e.g. Google tips that show up as you type in
+ a query). A downside of this approach is the large number of complexities, subtleties and incompatibilities
+ that still exist in the way different versions of popular browsers handle the DOM elements of a page.
+ </p><p style="width:90%">
+ JavaScript can handle the communication between client and server through an instance of a
+ specialized object. For quite a long time 2 approaches existed, the non-IE world (Firefox,Safari,Opera...)
+ used the XMLHttpRequest class to create this object, whereas IE (before IE7) used the ActiveXObject class.
+ With the release of IE7 Microsoft introduced native support for XMLHttpRequest class objects thus enabling
+ programmers with a unique method for the development of dynamic pages.
+ </p><p style="width:90%">
+ By creating an instance of this class a POST or GET request can be sent to the server and the response is
+ stored in a property ('returnedText') of the communication object. It's become widely customary to encode
+ these responses in XML messages. You can invent your own message structure (either based on XML or anything
+ else), but one has to be aware that if the http headers are properly set and the message returned to the
+ client is a well formed XML fragment, also the property XMLResponse is assigned with a reference to an object
+ that represents the DOM of the XML response. By means of the XML W3C DOM interface the programmer can easily
+ manipulate the data embedded in the XML message.
+ </p><p style="width:90%">
+ In this example a Rivet script initializes an array with the essential data regarding a few of the major
+ composers of the european music. This array plays the role of a database. The script sends back to the
+ client two types of responses: a catalog of the composers or a single record of a composer.
+ </p><pre class="programlisting">#
+# Ajax query servelet: a pseudo database is built into the dictionary 'composers' with the
+# purpose of emulating the role of a real data source.
+# The script answers with 2 types of responses: a catalog of the record ids and a database
+# entry matching a given rec_id. The script obviously misses the error handling and the
+# likes. Just an example to see rivet sending xml data to a browser. The full Tcl, JavaScript
+# and HTML code are available from http://people.apache.org/~mxmanghi/rivet-ajax.tar.gz
