cmder integrated terminal task issues

[Nonpareille]

Issue Type: Bug

1. Download cmder from http://cmder.net/ and set as integrated terminal for windows using instructions here https://code.visualstudio.com/docs/editor/integrated-terminal#_common-questions
2. Create a simple.bat file with @echo this works.
3. Make a shell task that runs simple.bat as the command.
4. Run said task.

Actual results:

> Executing task in folder test_project: simple.bat

C:\sandbox\test_project
λ 

Cursor sits there, echo does not happen and the task never completes.

Expected results:

> Executing task in folder test_project: simple.bat

this works

Thoughts:
If we must use the integrated terminal to run tasks, could we have an option to use a different shell for these tasks if they don't play nice with the task system?

You can specify a shell to use in the tasks.json file:

{
	"version": "2.0.0",
	"options": {
		"shell": {
			"executable": "cmd.exe",
			"args": [
				"/d", "/c"
			]
		}
	},
	"tasks": [
		{
			"label": "echo",
			"type": "shell",
			"command": "dir"
		}
	]
}

The options can be specified per tasks as well.

Do you know which command line args cmder use to execute a command and then quite (like /d /c for cmd.exe). Then I can add them. As a work around for now you can have the options in the tasks.json point to cmder.exe and use the right options.

@nicholasjbbaldwin any information?

The problem is that the VS Code documentation recommends doing this to start cmder:

"terminal.integrated.shell.windows": "C:\\WINDOWS\\System32\\cmd.exe",
"terminal.integrated.shellArgs.windows": ["/K", "C:\\cmder\\vscode.bat"]

and you can only have one /K or /C, so appending another one to do the task doesn't work. You'd need to to end up with an arguments array like:
["/K", "C:\\cmder\\vscode.bat", "&", "task_command", "task_arg"]

I am a little puzzled. Isn't cmder a standalone executable which supports something like /kor /Citself?

[patstew]

There is a cmder executable, but it's a full terminal emulator in its own right that can't be used as the integrated shell. See #12006
I'm not exactly sure how it all works, but AFAIK cmder is using clink.exe as the shell you interact with. It seems that clink.exe expects to be run inside cmd.exe, if you set it as vscode's integrated terminal it exits immediately.

[dbaeumer]

OK. Now I see. This is currently not possible since a tasks already passes a command to the cmd.exe. It would require that we add special code for cmder.exe that injects the vscode.bat into the command when executing.
