I created a preview using arc diff --preview.
I was wondering if I can update it using a command similar to arc diff --update revision_number (used for non-preview diffs)
What I tried so far:
arc diff --update preview_number(error:Usage Exception: Revision 'preview_number' does not exist!)arc diff --update Dpreview_number(error:Usage Exception: Revision 'preview_number' does not exist!)arc diff --update Diffpreview_number(error:Usage Exception: Parameter to --update must be a Differential Revision number)
Diff is just a change file and the unit for updating phab review updating a diff doesn't sound right. I think what you are looking for is a draft review (arc diff --draft). It will create a draft patch and you can update it as you see fit.
