// $ brew install bash-completion
// Once installed, bash completion must be evaluated. This can be done by adding the following line to the .bash profile:
// $ source $(brew --prefix)/etc/bash_completion
// Note for zsh users: [1] zsh completions are only supported in versions of zsh >= 5.2
// Examples:
// # Load the hcloud completion code for bash into the current shell
// source <(hcloud completion bash)
// # Load the hcloud completion code for zsh into the current shell
// source <(hcloud completion zsh)`

Short: "Output shell completion code for the specified shell",
Long: `To load completions:
### Bash
To load completions into the current shell execute:
source <(hcloud completion bash)
In order to make the completions permanent, append the line above to
your .bashrc.
### Zsh
If shell completions are not already enabled for your environment need
to enable them. Add the following line to your ~/.zshrc file:
autoload -Uz compinit; compinit
To load completions for each session execute the following commands:
mkdir -p ~/.config/hcloud/completion/zsh
hcloud completion zsh > ~/.config/hcloud/completion/zsh/_hcloud
Finally add the following line to your ~/.zshrc file, *before* you
call the compinit function:
fpath+=(~/.config/hcloud/completion/zsh)
In the end your ~/.zshrc file should contain the following two lines
in the order given here.
fpath+=(~/.config/hcloud/completion/zsh)
# ... anything else that needs to be done before compinit
autoload -Uz compinit; compinit
# ...
You will need to start a new shell for this setup to take effect.
### Fish
To load completions into the current shell execute:
hcloud completion fish | source
In order to make the completions permanent execute once:
hcloud completion fish > ~/.config/fish/completions/hcloud.fish
### PowerShell:
To load completions into the current shell execute:
PS> hcloud completion powershell | Out-String | Invoke-Expression
To load completions for every new session, run
and source this file from your PowerShell profile.
PS> hcloud completion powershell > hcloud.ps1
