Why

The TUI depends on cv4pve-cli output formats that are not a stable API:

  • the text format of config list
  • prune-backups arriving as a JSON string
  • the ip-addresses JSON string for CTs
  • the exit codes with --wait

All of this was verified against 2.4.0. After an upgrade, things may break in confusing ways.

Proposal

  • At startup, run cv4pve-cli --version.
  • If the version differs from the tested one, show a warning notification such as "tested with 2.4.0, found X".
  • Keep the tested version in one constant, next to a note in the README.

Done when

  • The warning shows for another version and stays silent for 2.4.0.
  • Tests are written first.
