Conemu: Arrow keys with WSL/ConEmu (again, but not just an issue, also possible solutions)

[wxiaoguang]

Versions

ConEmu build: 180626 x64
OS version: Windows 10 x64
Used shell version: WSL Ubuntu1804

Problem description

Define:

• OK (array keys work, no lag)
• WRONG_ARROW (array keys do not work)
• SLOW (serious UI lag when running the program)

Task {Bash::bash}:
conemu-cyg-64.exe -> wslbridge.exe -> bash.exe: nano SLOW, vim SLOW

Task customized 1:
bash.exe or ubuntu1804.exe: nano(OK), vim(WRONG_ARROW)

Task customized 2:
ubuntu1804.exe -cur_console:p5: everything seems OK

Question:

1. Is the wslbridge a must? Why it causes lag?
2. Will there be any problem just using ubuntu1804.exe -cur_console:p5? It seems a good solution.

The only proper solution is default {Bash::bash} task.
Others, even if they "seems" to be OK does not work completely.

For example:
ConEmu is not able to switch AppKeys mode and arrows will not work for you in some cases;
ConEmu is not able to retrieve current working directory from WSL shell;
256-colors is not working at all;

Just few issues I recall at once.

Well, you definitely may use ubuntu1804.exe -cur_console:p5 as ConEmu support any console application to be run in, but all bugs in that case should be addressed to Microsoft.

Microsoft is working on new PTY interface and I'm working on its support in ConEmu ;)
When things go to release I hope neither connector nor wslbridge would be required and speed is expected to be greatly improved.
