✓ Installed extension andyfeller/gh-sonar
✓ Pinned extension at 81a4ce86e027f31d306883c25a71b5d05b007e2e
This looks like it is pinned correctly. However...running gh ext list doesn't show it in blue (indicating pinned), and...
➜ gh ext upgrade gh-sonar --dry-run
[sonar]: would have upgraded from 81a4ce86 to 9977d8e5
✓ Successfully checked extension upgrades
Whereas a pinned extension would say:
➜ gh ext upgrade gh-sarif --dry-run
[sarif]: pinned extensions can not be upgraded
✓ Successfully checked extension upgrades
Separately, upgrading doesn't work at all, but that's another issue (to be created)
Acceptance Criteria
Given I installed a pinned, script-based GitHub CLI extension using gh ext install --pin SHA
When I execute gh ext upgrade <EXT> --dry-run
Then gh states pinned extensions can not be upgraded
Given I installed a pinned, script-based GitHub CLI extension using gh ext install --pin SHA
When I execute gh ext list
Then I see the extension sha is coloured cyan
In the following example, the version for gh-eco is colored cyan because it is a pinned extension:
