Seaside provides a layered set of abstractions over HTTP and HTML that let you build highly interactive web applications quickly, reusably and maintainably. It is based on Smalltalk, a proven and robust language that is implemented by different vendors. Seaside includes: 
 Programmatic HTML generation. A lot of markup is boilerplate: the same patterns of lists, links, forms and tables show up on page after page. Seaside has a rich API for generating HTML that lets you abstract these patterns into convenient methods rather than pasting the same sequence of tags into templates every time. Callback-based request handling. Why should you have to come up with a unique name for every link and form input on your page, only to extract them from the URL and request fields later? Seaside automates this process by letting you associate blocks, not names, with inputs and links, so you can think about objects and methods instead of ids and strings.
 Embedded components. Stop thinking a whole page at a time; Seaside lets you build your UI as a tree of individual, stateful component objects, each encapsulating a small part of a page. Often, these can be used over and over again, within and between applications - nearly every application, for example, needs a way to present a batched list of search results, or a table with sortable columns, and Seaside includes components for these out the box. Modal session management. What if you could express a complex, multi-page workflow in a single method? Unlike servlet models which require a separate handler for each page or request, Seaside models an entire user session as a continuous piece of code, with natural, linear control flow. In Seaside, components can call and return to each other like subroutines; string a few of those calls together in a method, just as if you were using console I/O or opening modal dialog boxes, and you have a workflow. And yes, the back button will still work. Seaside also has good support for CSS and Javascript, excellent web-based development tools and debugging support, a rich configuration and preferences framework, and more.

Seaside - Web framework for Smalltalk platforms

Pier is a content management system that is light, flexible and free. It aims at allowing users to manage their content from the browser. The central concept in Pier is the one of Structure. For example, the page is a structure. The blog is also a structure, A file is also a structure. Commands can be executed on a Structure. For example, a Structure can be edited, and once in edit mode, you can use the Pier syntax. In the original setup the commands appear in the footer, and are accessible after logging in. To make life easier, Pier also offers access to commands via Browser Keybindings. Any Structure can be Viewed. The default View is the one that renders the structure for normal usage. Another example, is the Browse View which offers a file system like view on the Pier structures. Any Structure has an environment which defines the template. To set the environment to be a different page use the Settings command. To edit the environment use the Edit Design command. A Structure can contain Widgets. For example, the environment of this page contains a menu widget on top, and a widget that enumerates the children of the current sturcture to the right. The seaside project website <A HREF="http://www.seaside.st/" target="_blank">http://www.seaside.st/</A> is powered by Pier CMS.
