Aws-cli: [V2] Command completion doesn't work

[furikake]

Running version on MacOS with iTerm2 and Oh My Zsh/Bash. Installed as per https://docs.aws.amazon.com/cli/latest/userguide/install-cliv2-macOS.html

❯ aws2 --version
aws-cli/2.0.0dev0 Python/3.7.4 Darwin/18.7.0 botocore/2.0.0dev0

Installed to:

❯ find /usr/local/bin -name "aws*"
/usr/local/bin/aws2
/usr/local/bin/aws2_completer
/usr/local/bin/aws
/usr/local/bin/aws_completer

aws2_completer is in path

❯ which aws2_completer
/usr/local/bin/aws2_completer
❯ which aws_completer
/usr/local/bin/aws_completer

Typing aws2 s3 <TAB> doesn't complete. Doing so with aws s3 <TAB> does.

[furikake]

Maybe it's user error though. Here's my .bashrc

$ grep aws ~/.bashrc
complete -C '/usr/local/bin/aws_completer' aws
complete -C '/usr/local/bin/aws2_completer' aws2

The error:

I've got same issue with aws2

Only slightly different stacktrace

This is not user error. Currently, auto completion is not functional when installing aws2 via the installers we distribute. This is something we're aware of and are looking into fixing.

I also noticed that there doesnt seem to be an aws2_zsh_completer.sh for zsh shells like there is for the aws v1. Will the auto completer for v2 also require this as well?

[Azatik1000]

I can't use zsh completion with aws2 too!

[hoangleanhtu]

I added following line in ~/.zshrc on Mac OS X then it works:

complete -C '/usr/local/bin/aws2_completer' aws2

[sdoyle88]

I added following line in ~/.zshrc on Mac OS X then it works:

complete -C '/usr/local/bin/aws2_completer' aws2

Thanks! That worked

[ed4becky]

zsh: command not found: complete

That is error I get when I try that solution

[furikake]

Looks like aws2_completer works with the current version. Maybe just needs docs to tell people how to configure it if the installer doesn't do it.

❯ aws2 --version
aws-cli/2.0.0dev3 Python/3.7.4 Darwin/19.2.0 botocore/2.0.0dev2

I've modified the oh-my-zsh plugin to use aws2. It's a bit crude but here's a link https://github.com/drgr33n/oh-my-zsh_aws2-plugin

[jonny-rimek]

I need to run
bash autoload bashcompinit bashcompinit
in my .zshrc before

complete -C '/usr/local/bin/aws_completer' aws

also note you have to remove the 2 if you install the GA version

[davidjmeier]

Documentation needs to be updated, but in the mean time those who are looking for a solution to Oh-My-Zsh completion this will get you to a working spot again...

plugins=(
...
[your plugins here]
...
)

# Check for AWS CLI v2 and enable plugin if exists.
if ! [[ -x "$(command -v aws)" ]]; then
  export IS_AWS=False
  echo "### Binary for aws not installed."
else
  export IS_AWS=True
  plugins+=(aws)
fi

# Activate Oh-My-ZSH
autoload bashcompinit
bashcompinit
source ${ZSH}/oh-my-zsh.sh

# Fix to enable AWS CLI v2 completion.
if [[ IS_AWS==True ]]; then
  complete -C '/usr/local/bin/aws_completer' aws
fi

Just know you can't use complete until the oh-my-zsh.sh is sourced since complete will fail otherwise. This variation will add aws to plugins only if it finds the aws cli binary. Hopefully this helps someone avoid a lot of wasted time - it seems as though the lack of documentation from AWS is causing a number of people to have issues. Hopefully someone from AWS will, minimally, address this.

@jonny-rimek what is _GA_ version ? I have put those 3 lines in my .zshrc and still no completion available :(

[jonny-rimek]

GA is generally availabe speaking of v2. during development of v2 the name was aws2. now that v2 is released the name is back to aws.

@cipri-tom you have oh-my-zsh installed and restarted your shell?

[cipri-tom]

@jonny-rimek nop, no OMZ, as I just started I wanna take it slow and understand what is going on.

Restarted, yes. I am getting an error, though:

complete:13: command not found: compdef when I enable the line of completion, although I have the other 2 lines as well (bashcompinit). I think it is coming from aws_completer

[Zwyx]

If you're using Oh My ZSH and have NVM on your system, then

complete -C aws_completer aws

must be put AFTER the NVM stuff in your .zshrs:

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

It's probably because $NVM_DIR/bash_completion rerun autoload bashcompinit or something like this.
