Dynamic Web Development
Sheerpower can be using as a browser scripting language. The first step is to activate the Sheerpower InterNet Services Web Server SPINS_WEBSERVER, also referred to as the spins webserver:
C:>spins_webserver
Sheerpower InterNet Services Web Server SPINS_WEBSERVER V10.135
Copyright (c) 2005-2022 Touch Technologies, Inc. - Thu, 20 Jun 2024 21:19:50
Listening IP address is 0.0.0.0
Spoofed>> "Server: Apache/2.4.52 (Ubuntu)"
Port 4, wwwroot is C:\Sheerpower\sphandlers\wwwroot\
Port 80, wwwroot is C:\Sheerpower\sphandlers\wwwroot\
The spins webserver has a lot of startup options. They can be seen by:
spins_webserver -?
On some systems, Windows might ask if it is okay if the spins_webserver accesses the network. Choose yes to continue.
To test that spins is working, type this url into your browser's address bar:
The browser will respond with:
You made it to the SPINS_WEBSERVER index.html
To change the default root folder (for example to c:\inetpub\wwwroot)
c:> \Sheerpower\sphandlers\spins_webserver -wwwroot c:\inetpub\wwwroot
Let's run our first Sheerpower script. The source code is in C:\Sheerpower\sphandlers\scripts\sp4gl,
and the program is called:
matrix.spsrc. To run it, use this url:
Note:
Inside a SheerPower script, %include files are treated in a
specific way:
- If the first line of the file contains an HTML tag, the entire content of the file is treated as HTML code and output directly to the browser.
- If the first line does not contain an HTML tag, the file is processed and executed as SheerPower code.
Explanation of [[ ]] Syntax in Sheerpower
The [[ ]] syntax in Sheerpower is used to embed Sheerpower code within an HTML document. This allows you to mix server-side logic with client-side HTML seamlessly.
How it Works
- Opening and Closing [[ ]]:
Code enclosed within [[ ]] is interpreted and executed as Sheerpower code. This syntax helps distinguish between HTML content and Sheerpower code.
- Usage in HTML:
You can use [[ ]] to include loops, conditionals, and other logic directly within your HTML. This is useful for generating dynamic content based on server-side processing.
Benefits
- Dynamic Content: Easily generate dynamic content based on server-side processing.
- Seamless Integration: Mix HTML and Sheerpower code without switching contexts.
- Flexibility: Use loops, conditionals, and other logic within HTML to create flexible and powerful web pages.
This feature is particularly useful in creating dynamic and interactive web applications, where the content can be generated and manipulated server-side before being sent to the client.
Summary: SheerPower's unique handling of %include
files bridges the gap between web design and software development. By
automatically distinguishing between HTML and code content, it allows webpage
designers to focus on creating and maintaining HTML independently, while code
developers work on the backend logic. This loose coordination minimizes
dependency, enabling both teams to contribute their expertise without
requiring detailed knowledge of each other's domain. This feature simplifies
collaboration, streamlines development, and ensures seamless integration of
design and functionality within a single application.
Below is the HTML code mixed with Sheerpower code.
Note: This code for matrix.spsrc is only runnable from your local computer,
inside of your browser.
