The Visual Tools Markup Language (VTML)
The phrase "customizing the development environment" means that you can change
the content and layout of tag editors by editing VTML files directly in the Allaire Visual
Tools. This makes it easy to update tag syntax or change embedded Help text.
You can also create your own editors. Many custom tag developers use VTML to build
tag editors to distribute with their tags libraries. You can find a selection of custom
dialogs and tag editors in the VTML section of the Allaire Developer Exchange.
Another Allaire language, the Wizard Markup Language (WIZML), is also described in
this chapter. WIZML enables you to design and build custom wizards to gather user
input and to drive application output.
Note
You use VTML to control and customize the following interface elements:
Customizing Tag Chooser and Expression Builder
The Tag Chooser and Expression Builder are important tools for Web development in
the visual tools.
The Tag Chooser contains all supported tag sets and is the primary interface for tag
selection in the visual tools.
The Expression Builder provides you with a hierarchical view of all supported
expression elements. Elements can be selected to create complex expressions for
insertion in applications and for other programming needs.
You can adapt these tools to meet new requirements imposed by the evolution of
HTML, CFML, JSP , other tag-based languages and supported Web technologies.
The content and the behavior of these tools is controlled by two templates:
MarkupTags.VTM and ExpressionElements.VTM. Both are located in the \Extensions\
subdirectory of your visual tools installation directory.
When used in this chapter, the term visual tools refers to HomeSite,
ColdFusion Studio and JRun Studio. VTML elements that are only
available in the Studio products are marked accordingly.
