Mandatory snippet variable values? [message #171511]

Hello,

Is there a way to have the Snippets view variable replacement dialog issue
a warning or error if the user does not fill in a value for a Snippet
variable? What we'd like to create are essentially mandatory variables
that the user must fill in before the Snippet can be inserted into the
editor.

I've looked at the following classes but don't see an easy way to do this
from my plugin.

DefaultSnippetInsertion
VariableItemHelper
VariableInsertionDialog

Any help would be appreciated.

No, there is no support for declaring a variable as being required.
The extension point does allow you to specify a default value,
though, so that barring the user clearing it, a value will be
present. If that isn't enough, you'll need to either subclass the
DefaultSnippetInsertion dialog to provide a UI that enforces that,
or open a feature request:
