Conemu: Strange Cursor Behavior When Using Vue CLI

[suksit]

Versions

ConEmu build: 180626 preview x64
OS version: Windows 10 Pro 1803 x64
Used shell version (Far Manager, git-bash, cmd, powershell, cygwin, whatever): git-bash

Problem description

Normally, pressing arrow up/down should move the arrow > on the left of the menu. But the console cursor is moved instead. Please see the GIF in Actual results.

Steps to reproduce

1. Install Nodejs
2. Install Vue CLI (npm install -g @vue/cli)
3. Run vue create test-project

Actual results

Expected results

We should be able to select the options in the menu using arrow up/down.

So I dig a little bit deeper and found that it may be related to the cygwin/msys terminal connector

The default Task for Git Bash looks like this

git-cmd.exe --no-cd --command=%ConEmuBaseDirShort%\conemu-msys2-64.exe /usr/bin/bash.exe -l -i -new_console:p

I then tried creating a new Task with this command instead

git-cmd.exe --no-cd --command=usr/bin/bash.exe -l -i -new_console:p

And the up/down arrows are now working correctly.

However, it would be great if you could fix the terminal connector so the default Task will work as expected as well 🙂

The bug is inside npm.
You may confirm that by starting outside of ConEmu the mintty from git bash (default git bash terminal).

Thanks for looking into it.

I'm closing this since it's not really ConEmu's issue.

[Maximus5]

So, do you confirm it's reproducible in mintty?

[suksit]

Yes. The behavior is the same on mintty.

However, I'm not sure where to report the issue now. Shoud it be Git for Windows or Vue CLI or npm? Do you have a suggestion? 😐

You are trying to run console application (npm/vue) designed for WinAPI from terminal designed for POSIX API. Image you try to run Notepad under Ubuntu (and I mean real Linux installation, not WSL).

Obviously you have to use either proper versions of software (npm designed for POSIX, Notepad compiled for Linux) or use wrappers like Wine.

Surprisingly there is wrapper in ConEmu too

ConEmuC -std -c vue create test-project

Thank you!

Now I can just alias vue='ConEmuC -std -c vue' and use it happily! 😆
