termshells¶
The repository termshell contains the core part of the crl.interactivesessions:
- shellstack f.k.a. InteractiveSession
- Shells including all registered shells and base shell but excluding e.g. msgpythonshell and associated remotemodules
The terminal, f.k.a. pexpect.spawn class shall be extended. The terminal should contain the controlling terminal state. The attributes associated with the controlling terminal state such as tty_echo are transfered to this new class. The shells may contain still desired terminal state or initial terminal states. However, the most part of the terminal helper methods should be transferred from shell to this terminal. Shell could still provide for convenience shortcuts to these new terminal methods. Moreover, a new base class for the terminal should be written in order to make unit testing of the shells easier.
The shellstack should be merely a simple stack manager for the shells, nothing else. The idea is to try to keep the push and pop methods simple and transfer the special implementation to the shells and to the terminal. The tight coupling to pecpect should be removed and instead shellstack should be given the terminal factory or spawner in the __init__ or in the separate method.
