There's a cyclic dependency on siderolink library which imports talos machinery back. We will fix that after we get talos pushed under a new name. Signed-off-by: Andrey Smirnov <andrey.smirnov@talos-systems.com>

Use: "completion SHELL",
|
|
Short: "Output shell completion code for the specified shell (bash, fish or zsh)",
|
|
Long: `Output shell completion code for the specified shell (bash, fish or zsh).
|
|
The shell code must be evaluated to provide interactive
|
|
completion of talosctl commands. This can be done by sourcing it from
|
|
the .bash_profile.
|
|
|
|
Note for zsh users: [1] zsh completions are only supported in versions of zsh >= 5.2`,
|
|
Example: `# Installing bash completion on macOS using homebrew
|
|
## If running Bash 3.2 included with macOS
|
|
brew install bash-completion
|
|
## or, if running Bash 4.1+
|
|
brew install bash-completion@2
|
|
## If talosctl is installed via homebrew, this should start working immediately.
|
|
## If you've installed via other means, you may need add the completion to your completion directory
|
|
talosctl completion bash > $(brew --prefix)/etc/bash_completion.d/talosctl
|
|
|
|
# Installing bash completion on Linux
|
|
## If bash-completion is not installed on Linux, please install the 'bash-completion' package
|
|
## via your distribution's package manager.
|
|
## Load the talosctl completion code for bash into the current shell
|
|

## Write bash completion code to a file and source if from .bash_profile
