comparison flatpak/libervia_wrapper.py @ 171:a213053a03be
flatpak: update files following names change + Python 3 update:
- `build_manifest.py` has been fixed to work with recent SàT/Libervia
- filenames/scripts have been udpated to reflect project name change
- installation now uses `requirements.txt` when dev version is requested
- there are now 3 types of commands wrapper:
* `libervia_wrapper.py` uses `pb` bridge, starts backend before frontend, and stops it
when frontend is stopped. It's used by `Libervia Desktop` (Cagou)
* `libervia_wrapper-dbus.py` uses `dbus` bridge, starts backend before frontend, and
stops it when frontend is stopped. It's used for `Libervia TUI` (Primitivus)
* `libervia_wrapper-dbus.py` uses `dbus` bridge, starts backend if necessary and
doesn't stop it (to avoid waiting for backend start next time). It's used by
`Libervia CLI` (jp).
