// # bash
|
|
// To install auto-completion for V in bash, simply add this code to your `~/.bashrc`:
|
|
// `source /dev/stdin <<<"$(v complete setup bash)"`
|
|
// On more recent versions of bash (>3.2) this should suffice:
|
|
// `source <(v complete setup bash)`
|
|
//
|
|
// # fish
|
|
// For versions of fish <3.0.0, add the following to your `~/.config/fish/config.fish`
|
|
// `v complete setup fish | source`
|
|
// Later versions of fish source completions by default.
|
|
//
|
|
// # zsh
|
|
// To install auto-completion for V in zsh - please add the following to your `~/.zshrc`:
|
|
// ```
|
|
// autoload -Uz compinit
|
|
// compinit
|
|
// # Completion for v
|
|
// v complete setup zsh | source /dev/stdin

// Please note that you should let v load the zsh completions after the call to compinit
