It happens to everyone—you spend forever digging around in your filesystem for the dataset you need to finish your work. But you can’t remember the name or enough about the contents to be able to search for it. Searching is wasted time, time that would be far better spent on productive tasks.
What users like myself really need is for our tools to reflect the way we actually work, and that’s where project-based workflows in tools like Wolfram Workbench come in.
When working with Mathematica, we need notebooks—some will contain rough work and some will be presentation material. We may also need some data and other forms of output, such as HTML for final delivery. So let’s walk through setting up a project, and some of the features that can enhance your workflow and improve your productivity.

Wolfram|Alpha‘s mission—to make all systematic knowledge immediately computable by anyone—is a major software engineering effort. With millions of lines of code and hundreds of team members, a sophisticated code-base manager is essential in making the project possible. Enter Wolfram Workbench.
Wolfram Workbench 2, the recently released version of Wolfram’s state-of-the-art software engineering and deployment tool, is used at all levels of the Wolfram|Alpha project, from data curation and quality assurance to documentation and framework development. With its leading code-editing, navigation, and project-management tools, Workbench is a scalable solution that is necessary for building and growing Wolfram|Alpha.
In this video, two Wolfram|Alpha developers describe Workbench‘s invaluable role in the project.

Wolfram Workbench 2 is out today. New in Version 2 is the ability to create and integrate documentation for your Mathematica applications, as well as a host of improvements to code editing, navigation, and more.
Workbench is an Eclipse-based integrated development environment (IDE) with a powerful suite of tools to help you quickly create innovative, next-generation applications from concept to completion. You can work with any Eclipse-supported language, making Workbench a very efficient organizational tool. It’s a powerful tool for small projects as well as large scale applications. How do we know? It is one of our key tools in the development of Mathematica, Wolfram|Alpha, and other Wolfram technologies.

Inside and outside of Wolfram Research, teams are working on large Mathematica projects. Working with large code bases requires powerful tools; it is even better if these tools are integrated. With Wolfram Workbench, we brought an integrated development environment (IDE) to our users.
What does “integrated” mean? Well, let’s look at just one example of how Workbench integrates Mathematica‘s central language features, pattern matching, editors, and source management tools.
Let’s start with a specific problem: with our Mathematica 6.0 release, we overhauled many of our libraries and APIs (our recent Version 7.0 release builds on the improvements in Version 6.0). Some groups of functions were deprecated or their APIs changed. We had collected a long list of these changes… but how would users apply them to their source code? Go through them one by one and line by line in their code? Definitely not.

Last month, we hosted our annual technology conference here at our headquarters in Champaign, Illinois, where hundreds of Mathematica users from around the world came to show us what they’ve been working on and to see what we’ve been up to.
A lot of the conference presentations are now available on our website, so you can take a look at them even if you didn’t have a chance to attend this year.

In this blog and elsewhere, you’ll often see the statement that some advanced Mathematica feature is just another application of symbolic programming. It’s the kind of idea that seems too powerful to explain in a single blog post, yet simple enough that I am tempted to try. So, here goes.
Symbolic programming is based on the concept of recasting core features of human language into a computationally active form.
What does it mean to have a human-language-oriented programming language?
Our cognitive model of computation is typically a three-stage process: 1) describing the computation, 2) executing that description, and 3) outputting the results.
The “language” part of most programming languages begins and ends with stage one. Linguistic structures are erected to describe the program. But the execution of the program is typically oriented around an entirely different system of types and objects; and likewise, the program’s output structure tends to resemble nothing particularly language-like.
Symbolic programming uses linguistic structures as the foundation of all aspects of computation. From a computation’s description, to how the computation executes, to how humans interface with the results, the exact same basic tree structure is used throughout.
This is a powerful unification, making possible many useful computations that in other systems range from cumbersome to practically impossible. We’ll see examples along the way, but let me first describe what these linguistic structures actually are.

I’ve been a “professional” user-interface programmer for 20 years. In that time I’ve written a grand total of three little apps just for the fun of it. Two of them I snuck in as hidden buttons in the Mathematica About Box, because it was just too difficult to start a new application from scratch. All of them can be replicated in a few minutes using Version 6.
In my experience, writing GUI (graphical user interface) applications in C or Java or Visual Basic–or whatever–is fine if you plan to spend weeks or months on a program, but prohibitively horrible if you really only have a few minutes to dedicate to the task.
You have to allocate windows, store pointers to them, then allocate controls or read them from some kind of resource file, store pointers to them, blah, blah, blah. It might be two or three pages of code before you can even start thinking about what this program is actually supposed to do.
Cocoa and other such frameworks make it marginally easier. I enjoyed programming in NeXTSTEP (which is what Cocoa was called before Apple took over NeXT). It’s the environment in which I wrote RealTimeAlgebra in 1989, the one just-for-fun app I wrote not as an About Box button. (RealTimeAlgebra was basically what we now call Manipulate.)
But it is still a pain. Instead of starting by writing pages of code to deal with windows, you start by using an annoying graphical tool to lay out controls and define who is connected to whom. Then you get to write pages of code defining the actions of all these controls before you can start working on the actual content.

Symbolic programming has been a core idea in Mathematica since the very beginning. But it is big idea, and an abstract idea. And people understandably just want to know what the bottom-line benefit is, and could care less about what went into making it happen. Fortunately, Mathematica 6 is making it a lot easier to illustrate ideas about symbolic computation in visual and interactive forms.
For starters, illustrating the core programming primitives with visual examples is a piece of cake with the new graphics and typesetting functions. For example, Map will take a function and apply it to each element in a list:
NestList will take a function and apply it over and over again to the initial seed, returning a list of all the iterations:
Programming in Mathematica is based on transforming trees. The built-in function TreeForm allows us to visually represent the tree backbone of Mathematica programs and data structures:
