depot views

This folder contains external views of depot content, defined using josh workspaces. See the individual views for a description of their individual content and usage information.

Testing changes locally

Generally, when iterating on these files, it's best to locally invoke josh- filter (from //third_party//josh) locally to inspect how the workspace would look like:

  • Commit your changes. This is required, as josh-filter operates on your HEAD, not working directory state.
  • Invoke josh-filter with the filter expression, for example josh-filter ':workspace=views/kit'.
  • Peek at the synthesized git history by looking at FILTERED_HEAD.

Testing changes in Gerrit

It's also possible to clone resulting workspaces for CLs that were already pushed to Gerrit, but didn't land in master yet.

For CL1234 at revision 2, the URL passed to git clone would look like this:
