How to Change Submodule Branch Commit

Steps

These instructions assume you are in TACC/Core-CMS and have already run git submodule init and gist submodule update.

1. Change the pinned commit of submodule.
   (Downloads code from different commit of cms-site-resources repo to taccsite_custom/.)

   # Navigate into submodule (from root of this repo)
   cd taccsite_custom
   # Checkout different commit of submodule repo
   git checkout main_or_other_branch_or_commit
   # Update commit of submodule repo (as necessary)
   git pull # (or git fetch […], etc.)

2. Save the pinned commit of submodule.
   (Updates the pinned commit of cms-site-resources repo at taccsite_custom/.)

   # Navigate back to this repo (from root of submodule repo)
   cd ../
   # Commit this repo's pointer to a different commit of submodule repo
   git add taccsite_custom
   git commit -m "[…] Update submodule to get […]"

3. Push the change to a relevant branch.
   (So that the change can be reviewed with relevant Core code changes, if any.)
