The process spawned by `poetry shell` is a terminal emulator driven by the pexpect and cleo packages. It hijacks and proxies the user's keystrokes before sending them to the underlying terminal.
- wyuenho 4y agoCleo creates "subcommands" in a git like manner, whereas pexpect spawns a subshell. That cleo Terminal class you see is only a viewport. A terminal emulator will be something substantially more complex such as libvterm. If it ain't handling terminfo, it ain't a terminal emulator. https://launchpad.net/libvterm https://launchpad.net/libvterm
- ak217 4y agoThat is the point I was making. It's not a proper terminal emulator, instead it's a half-assed one. If it gets between the user's keystrokes and the host shell, it should be a proper emulator. Otherwise it should set up the environment and get out of the way.
