aws
aws_completer does not auto complete command aliases, even though aliases are displayed as valid choices in error message
Describe the feature
Currently, if you were to type an invalid subcommand, you get back a list of valid subcommands
$ aws ec2 in
usage: aws [options] <command> <subcommand> [<subcommand> ...] [parameters]
To see help text, you can run:
aws help
aws <command> help
aws <command> <subcommand> help
aws: error: argument operation: Invalid choice, valid choices are:
accept-address-transfer | accept-reserved-instances-exchange-quote
accept-transit-gateway-multicast-domain-associations | accept-transit-gateway-peering-attachment
[...]
This list actually includes custom aliases defined in ~/.aws/cli/alias
$ aws ec2 in
usage: aws [options] <command> <subcommand> [<subcommand> ...] [parameters]
To see help text, you can run:
aws help
aws <command> help
aws <command> <subcommand> help
aws: error: argument operation: Invalid choice, valid choices are:
accept-address-transfer | accept-reserved-instances-exchange-quote
accept-transit-gateway-multicast-domain-associations | accept-transit-gateway-peering-attachment
accept-transit-gateway-vpc-attachment | accept-vpc-endpoint-connections
[....]
withdraw-byoip-cidr | wait
instances-running-table | instances-stopped-table
instances-status | help
$
However, aws_autocomplete does not seem to have available the aliases to be auto completed. The below command does not display any of the instances-* commands as shown in the error message above.
$ aws ec2 in<tab>
The aws_completer command doesn't include the alias in it's results
$ COMP_LINE="aws ec2 i" aws_completer
import-client-vpn-client-certificate-revocation-list
import-image
import-key-pair
import-snapshot
$
Use Case
It is much faster to use autocomplete to complete long commands as well as to remind oneself of what commands exist based on a known prefix. This should include custom aliases which are created in the ~/.aws/cli/alias file.
Proposed Solution
Make sure the same method of building the list of available subcommands in error messages is used by aws_completer to build available command and subcommand choices including aliases from ~/.aws/cli/alias.

Hello @isleshocky77, thank you for reaching out. I will provide to the team about this feature request if feasible where to have a completer where it follows the alias. I will update you as soon as I get updates. If you have any questions, please do let me know. Thanks.
