Snapshot Publishing is a feature of the Comala Publishing app to create a snapshot of a document. Comala Document Management integration with Comala Publishing allows the creation of a snapshot document of a Confluence page using a workflow trigger.

Activating snapshot publishing

There are three steps to setting up snapshot publishing to take place on a Comala workflow event:

1. Install Comala Publishing to your instance and enable snapshot publishing for a space

2. Set up snapshot publishing in your space tools snapshot publishing dashboard

3. Update your workflow to trigger the snapshot publishing process and apply to your documents (see below)

Publishing a snapshot using a workflow trigger

A snapshot can be published using

• the snapshot-page macro to create a snapshot that is added to a specified snapshot collection

• the pdf-export macro to create a snapshot that is added to the page as an attachment

Snapshot-page action trigger workflow markup

The publishing is triggered by an action macro, snapshot-page, which must be used in a trigger.

{workflow:name=Snapshot Publishing}
   {state:Editing|submit=Review}
   {state}
   {state:Review|approved=Published|rejected=Editing}
      {approval:Review|assignable=true}
   {state}
   {state:Published|final=true|updated=Editing}
   {state}
   {trigger:statechanged|state=Published}
      {set-metadata:lastapprover}
      @user@
      {set-metadata}
      {snapshot-page:collection=mycollection|editor=@lastapprover@}
   {trigger}
{workflow}

The example markup above based on the example from same-space publishing, but we've added the trigger at the bottom.

When the state changes to Published, the trigger is activated and the snapshot-page macro instructs the Comala Publishing app to create a snapshot document from the Confluence document.

• the collection parameter value is required to add the snapshot to a named collection

• the editor parameter value is the user who is set as the creator of the snapshot document

In the example above

• the value for the collection parameter must be the name of a snapshot collection that has been linked to or created in the space by the space administrator

• the value for the editor parameter is a metadata value set in the workflow trigger prior to the snapshot-page macro action

pdf-export action trigger workflow markup

With Comala Publishing installed, the pdf-export macro can be used as an action to export a snapshot of page or blog post in PDF format and adds the pdf to the page as an attachment.

The pdf is added with a filename in the following format:

• <confluence_filename>_<document_version>_<date_pdf_file_created>_<time_pdf_created>.pdf

{trigger:statechanged|state=Published}
      {pdf-export}
{trigger}

There are no macro parameters to configure.
