# vi-mode plugin

This plugin increase `vi-like` zsh functionality.

To use it, add `vi-mode` to the plugins array in your zshrc file:

```zsh
plugins=(... vi-mode)
```

## Settings

- `VI_MODE_RESET_PROMPT_ON_MODE_CHANGE`: controls whether the prompt is redrawn when
  switching to a different input mode. If this is unset, the mode indicator will not
  be updated when changing to a different mode.
  Set it to `true` to enable it. For example:

  ```zsh
  VI_MODE_RESET_PROMPT_ON_MODE_CHANGE=true
  ```

  The default value is unset, unless `vi_mode_prompt_info` is used, in which case it'll
  automatically be set to `true`.

- `MODE_INDICATOR`: controls the string displayed when the shell is in normal mode.
  See [Mode indicator](#mode-indicator) for details.

## Mode indicator

*Normal mode* is indicated with a red `<<<` mark at the right prompt, when it
hasn't been defined by theme.

You can change this indicator by setting the `MODE_INDICATOR` variable. This setting
supports Prompt Expansion sequences. For example:

```zsh
MODE_INDICATOR="%F{yellow}+%f"
```

You can also use the `vi_mode_prompt_info` function in your prompt, which will display
this mode indicator.

## Key bindings

Use `ESC` or `CTRL-[` to enter `Normal mode`.

NOTE: some of these key bindings are set by zsh by default when using a vi-mode keymap.
