How do I integrate MSYS2 shell into Visual studio code on Window?

by

To inhibit the working directory change from your current directory, set the CHERE_INVOKING environment variable to a non-empty value:

    "terminal.integrated.env.windows": {
        "CHERE_INVOKING": "1"
    },

In MSYS login scripts, setting the CHERE_INVOKING variable serves only to prevent a shell from doing a cd "${HOME}", and nothing else.

If you require a MinGW toolchain, set the MSYSTEM environment variable to select a toolchain. Recognized values are MSYS (default), MINGW32 or MINGW64.

    "terminal.integrated.env.windows": {
        "MSYSTEM": "MINGW64",
    },

In full, the VS Code settings might look like so:

{
    "terminal.integrated.shell.windows": "C:\\msys64\\usr\\bin\\bash.exe",
    "terminal.integrated.shellArgs.windows": [
        "--login",
    ],
    "terminal.integrated.env.windows": {
        "CHERE_INVOKING": "1",
        "MSYSTEM": "MINGW64",
    },
}

To provide some context on the very cryptic nomenclature of CHERE_INVOKING: chere is apparently a Cygwin command for installing and managing a “Command Prompt Here” folder context menu item. Although MSYS2 inherits the environment variable from Cygwin, it doesn’t actually inherit the command itself.
