Get fish shell to work with gcloud command line tools?

Question

Has anyone had any luck getting fish shell to work with google's gcloud command line tools? I'm not an expert in Fish script but these are the two files gcloud needs to run (which work fine use Fish's bash mode). Fish doesn't allow you to source bash files from what I understand so these would need to be converted to Fish script?

path.bash

script_link="$( readlink "$BASH_SOURCE" )" || script_link="$BASH_SOURCE"
apparent_sdk_dir="${script_link%/*}"
if [ "$apparent_sdk_dir" == "$script_link" ]; then
  apparent_sdk_dir=.
fi
sdk_dir="$( command cd -P "$apparent_sdk_dir" && pwd -P )"
bin_path="$sdk_dir/bin"
export PATH=$bin_path:$PATH

path.completion

_python_argcomplete() {
    local IFS=''
    COMPREPLY=( $(IFS="$IFS"                   COMP_LINE="$COMP_LINE"                   COMP_POINT="$COMP_POINT"                   _ARGCOMPLETE_COMP_WORDBREAKS="$COMP_WORDBREAKS"                   _ARGCOMPLETE=1                   "$1" 8>&1 9>&2 1>/dev/null 2>/dev/null) )
    if [[ $? != 0 ]]; then
        unset COMPREPLY
    fi
}
complete -o default -F _python_argcomplete "gcloud"

_completer() {
    command=$1
    name=$2
    eval '[[ "$'"${name}"'_COMMANDS" ]] || '"${name}"'_COMMANDS="$('"${command}"')"'
    set -- $COMP_LINE
    shift
    while [[ $1 == -* ]]; do
          shift
    done
    [[ $2 ]] && return
    grep -q "${name}\s*$" <<< $COMP_LINE &&
        eval 'COMPREPLY=($'"${name}"'_COMMANDS)' &&
        return
    [[ "$COMP_LINE" == *" " ]] && return
    [[ $1 ]] &&
        eval 'COMPREPLY=($(echo "$'"${name}"'_COMMANDS" | grep ^'"$1"'))'
}

unset bq_COMMANDS
_bq_completer() {
    _completer "CLOUDSDK_COMPONENT_MANAGER_DISABLE_UPDATE_CHECK=1 bq help | grep '^[^ ][^ ]*  ' | sed 's/ .*//'" bq
}

unset gsutil_COMMANDS
_gsutil_completer() {
    _completer "CLOUDSDK_COMPONENT_MANAGER_DISABLE_UPDATE_CHECK=1 gsutil help | sed /Additional/q | grep '^  ' | sed -e 's/^  //' -e 's/ .*//'" gsutil
}

unset gcutil_COMMANDS
_gcutil_completer() {
    _completer "CLOUDSDK_COMPONENT_MANAGER_DISABLE_UPDATE_CHECK=1 gcutil help | grep -v '^information' | grep '^[a-z]' | sed -e 's/ .*//' -e '/^$/d'" gcutil
}

complete -o default -F _bq_completer bq
complete -o default -F _gsutil_completer gsutil
complete -o default -F _gcutil_completer gcutil

What worked for me was just using bass. Check it out: https://github.com/edc/bass

Just take the lines that gcloud adds to your bash_profile, and prepend bass to them in your .config/fish/config.fish file, as follows:

# The next line updates PATH for the Google Cloud SDK.
bass source '/Users/hunter/bin/google-cloud-sdk/path.bash.inc'

# The next line enables shell command completion for gcloud.
bass source '/Users/hunter/bin/google-cloud-sdk/completion.bash.inc'

As of today, I was able just to do

1. brew install --cask google-cloud-sdk
2. Added source /usr/local/Caskroom/google-cloud-sdk/latest/google-cloud-sdk/path.fish.inc to my ~/.config/fish/config.fish
3. Clone https://github.com/aliz-ai/google-cloud-sdk-fish-completion then run install.sh.

For path.bash, all it does is add the Cloud SDK bin directory to your PATH. We put some weird stuff in there because we wanted it to work from inside the Cloud SDK directory even when behind, eg, a symlink. For your own system, just do the fsh equivalent of "export PATH=$PATH:/path/to/google-cloud-sdk/bin".

For the tab completion, I don't know how fsh's tab completion works, so I've got nothing.
