New features

[Gustavo Marin]

Thinks I'd like to add:

• hostctl sync k8s -n namespace -p profile
• hostctl sync minikube -p profile
• hostctl sync docker -p profile
• hostctl sync docker-compose -f docker-compose.yml -p profile

Also with a --watch flag to monitor and react to changes

[Julien Virey]

• shell completion for available flag / command
• shell completion for available domains for remove domains and set domains commands
• shell completion for -p, --profile flag value (i.e., profile available in user hosts).

A common use-case is to add a command like:

hostctl init --shell [bash | zsh | fish | ...]

This command can be eval from the user shell dotfile and output the completion for the selected shell.

To have the profile / domains completion, a --batch flag to the list command can list available values:

# hostctl list --batch --column profile
default
site1
site2

# hostctl list --batch --column ip
192.168.10.10
192.168.10.11

I like that about autocomplete and show columns.

Not sure I understand the --batch flag

[Julien Virey]

Like mysql:

--batch, -B
Print results using tab as the column separator, with each row on a new line

It would be used to remove the decoration of the output.

# mysql -e 'show processlist;'

# mysql --batch -e 'show processlist;'

920843	system user		NULL	Slave_SQL	4494	Slave has read all relay log; waiting for the slave I/O thread to update it	NULL	0.000
921884	root	localhost	NULL	Query	0	init	show processlist	0.000

Oh I see, I'm not sure if batch is the best name, but the feature may be useful.

I think we can do two things for this, one is a flag like --output clean (as opposed to the table default) and then a preference file (like $HOME/.hostctl/config`) where you can set different defaults options.

I think we can do two things for this, one is a flag like --output clean

or --output raw

The use case for the output without a table decoration is:

• use it for completion
• use it to pipe in other unix tool (awk / grep / less ...)

So I don't know if a preference in a config file is needed for that.

Cobra seem to provide ressources to generate completion, there is some documentation available here: https://github.com/spf13/cobra/blob/master/bash_completions.md

@BarbUk I've implemented --raw output and --column selection, but after reading the guides on autocompletion for cobra I cannot make it work. If you want to give it a try, there is an open branch/PR #28 that you can start from

Moving this list to #45
