Theia - Editor Preview Extension

A Preview Editor supports the same functionality as a regular editor widget with the exception: if a preview editor has not "transitioned to a permanent editor" at the time an additional request to preview a file is received, instead of opening a new editor, it will display the contents of the newly requested file.

Events that will transition the preview to a permanent editor are as follows:

• Modifying file contents being previewed
• Double clicking the preview tab
• Performing a drag/drop operation of the editor preview tab resulting in the tab being moved.
• Issuing a request to open the file being previewed (e.g. double clicking the file in the navigator)

The preview editor is enabled by default when the extension is included in a Theia application, but may be disabled by modifying the preference:

editor.enablePreview

In addition to this value, the preference:

list.openMode

must be set to "singleClick" to enable opening files in preview mode.
