A workaround for people who prefer entering password in tty when possible (e.g. using pinentry-mode loopback) but don't want to break vscode commit signing:

1. Create a ~/.local/bin/my-pinentry.sh:

#!/bin/sh
if [ "$PINENTRY_USER_DATA" = "tty" ]; then
    exec /usr/bin/pinentry-tty "$@"
else
    exec /usr/bin/pinentry "$@"
fi

asdf_shell() {
    export "ASDF_${1:u}_VERSION"="$2"
}

# and completion for zsh assuming ASDF_DATA_DIR is set
_asdf_shell_1() {
    local -a plugins=( "${ASDF_DATA_DIR:?}/plugins"/*(:t) )
    compadd -a plugins
}
_asdf_shell_2() {
