Introduction

Templates are shortcuts for frequently used fragments of text such as code patterns or complex text entities. They may contain variables which are only resolved at the time when the template is inserted within a context. Together with linked mode, inserting a template can create a on-the-fly edit mask within a text viewer.

Templates are specified as text, variables are defined using the ${variable} notation known from Ant, for example. The following snippet shows an example template for an instance check in Java:
if (${name} instanceof ${type}) {
    ${type} ${new_name} = (${type})${name};
    ${cursor}
}
In this template, the variables (name,type, ...) are resolved when inserted into java source and changing one variable instance will also change the other. When leaving linked mode, the caret is placed at the cursor variable.

Template functionality can be added to a custom text editor by offering TemplateProposals as content assist choices, which is simplified by using a subclass of TemplateCompletionProcessor. User template management can be offered by including a TemplatePreferencePage which uses a TemplateStore and ContextTypeRegistry as the underlying model to store templates. The org.eclipse.ui.editors.templates extension point can be used to allow other plug-ins to contribute templates to an editor. This is accomplished by using the ContributionTemplateStore and ContributionContextTypeRegistry subclasses of the above types.

Template variables are resolved by a TemplateVariableResolver. GlobalTemplateVariables offers some default variables such as date, user, and selection, but advanced features such as resolving to language constructs can be performed in subclasses.
