Toolmakers Respond to Boom in Scripting
Using scripting in the right parts of an application stack, to do the right things, is a complex and subjective challenge of finding the right fit between talents and technologies. Writing, debugging and testing scripts is a more straightforward but nontrivial challenge of finding the right fit between complexity and capability.
Toolmakers, recognizing the white-hot interest of system administrators and applications developers in putting scripts to work in more tasks, are responding with innovation and integration to create attractive script development alternatives.
Scripting languages dont have a long tradition of elaborate, integrated development environments because the scripting cycle hasnt normally needed to orchestrate editing, compiling, debugging and performance profiling. Scripts have tended to be produced with ordinary text editors and invoked merely by pointing the scripting engine at the location of the file containing a series of statements.
As scripting moves into more complex roles, developers are increasingly interested in more broadly capable integrated tool sets for script development. Fortunately, this comes at a time when comprehensive tool suites are becoming ever more affordable, as open-source projects spin off productivity aids to create an aggressive competitive environmentone that makes SlickEdits pricing look increasingly out-of-date.
With their vital role in the fast-growing world of open-source enterprise software, these three "P" languages are supported by an equally fast-growing array of tools and environments. A leading example is Komodo 3.1, an integrated development environment for dynamic languages from ActiveState (www.activestate.com).
Built on the Mozilla platform, Komodo offers developers multilanguage editing with code navigation, Web page previewing, debugging and extensibility with macros. A personal version, lacking large-project support tools and restricted to noncommercial use, can be obtained for less than $30.
In addition to using scripting tools for administrative and text-file processing tasks, and for adding interactive behavior to the browser-based Web experience, developers can look forward to applying their skills and tools for dynamic scripting in an expanding array of execution environments. The Java virtual machine, for example, is on a path toward supporting dynamic languages, as well as the bytecode-compiled Java language, and both Microsoft Corp. and third parties offer scripting tools that plug into Microsofts Visual Studio .Net workbench.
Scriptings heritage is largely in the Unix space, but it becomes more universal with the availability of products such as MKS Inc.s Toolkit 9.0, released in June, which hosts traditional Unix tools on Windows and can package a script as a Windows service (www. mkssoftware.com). Microsofts .Net environment supports similar functions with surprisingly similar code in dynamic languages such as Perl or VBScript, as well as C#.
Scripting is also becoming integrated into the development environments and component libraries offered to Java developers, as illustrated by the provision of AJAX components in the Version 2 update of Sun Java Studio Creator expected this fall from Sun Microsystems Inc. (reviewed in early-access form by eWEEK Labs on Page 40).
To maximize their gains, those evaluating scripting tools should pay heed to standards compliance. Rapid response to evolving language definitions, as well as to the continuing refinement of scripting target platforms such as Mozilla, requires agility from toolmakers to preserve the freedom of developers.
