## Getting Started

### Installation

**npm (recommended)**
```shell
npm install -g @microsoft/inshellisense
is init
```
**homebrew (macOS/linux)**
```shell
brew tap microsoft/inshellisense https://github.com/microsoft/inshellisense
brew install inshellisense
is init
```

### Updating

```shell
npm install -g @microsoft/inshellisense # OR brew upgrade inshellisense
is reinit
```

### Quickstart

After completing the installation, run `is doctor` to verify your installation was successful. You can run `is` to start the autocomplete session for your desired shell. Additionally, inshellisense is also aliased under `inshellisense` after installation.

### Shell Plugin

If you'd like to automatically start inshellisense when you open your shell, run the respective command for your shell. After running the command, inshellisense will automatically open when you start any new shell session:

```shell
# bash
is init bash >> ~/.bashrc

# zsh
is init zsh >> ~/.zshrc

# fish
is init fish >> ~/.config/fish/config.fish

# pwsh
is init pwsh | Add-Content $profile

# powershell
is init powershell | Add-Content $profile

# xonsh
is init xonsh >> ~/.xonshrc

# nushell
is init nu | save $nu.env-path --append
```

> [!NOTE]  
> When updating your shell configuration in the future, make sure the inshellisense plugin is the last command in the file. Including commands after it may break the configuration (ex. initializing your shell plugin manager after the inshellisense plugin)

### Usage

| Action                                | Command | Description                                      |
| ------------------------------------- | ------- | ------------------------------------------------ |
| Start                                 | `is`    | Start inshellisense session on the current shell |
| Stop                                  | `exit`  | Stop inshellisense session on the current shell  |
| Check If Inside Inshellisense Session | `is -c` | Check if shell inside inshellisense session      |

#### Keybindings

All other keys are passed through to the shell. The keybindings below are only captured when the inshellisense suggestions are visible, otherwise they are passed through to the shell as well. These can be customized in the [config](#configuration).

| Action                    | Keybinding     |
| ------------------------- | -------------- |
| Accept Current Suggestion | <kbd>tab</kbd> |
| View Next Suggestion      | <kbd>↓</kbd>   |
| View Previous Suggestion  | <kbd>↑</kbd>   |
| Dismiss Suggestions       | <kbd>esc</kbd> |

## Integrations

inshellisense supports the following shells:

- [bash](https://www.gnu.org/software/bash/)
- [zsh](https://www.zsh.org/)
- [fish](https://github.com/fish-shell/fish-shell)
- [pwsh](https://github.com/PowerShell/PowerShell)
- [powershell](https://learn.microsoft.com/en-us/powershell/scripting/windows-powershell/starting-windows-powershell) (Windows Powershell)
- [cmd](https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/cmd) _(experimental)_
- [xonsh](https://xon.sh/)
- [nushell](https://www.nushell.sh/)

## Configuration

All configuration is done through a [toml](https://toml.io/) file. You can create this file at `~/.inshellisenserc` or, for XDG compliance, at `~/.config/inshellisense/rc.toml`. The [JSON schema](https://json-schema.org/) for the configuration file can be found [here](https://github.com/microsoft/inshellisense/blob/main/src/utils/config.ts).

### Keybindings

You can customize the keybindings for inshellisense by adding a `bindings` section to your config file. The following is the default configuration for the [keybindings](#keybindings):

```toml
[bindings.acceptSuggestion]
key = "tab"
# shift and ctrl are optional and default to false
shift = false
ctrl = false

[bindings.nextSuggestion]
key = "down"

[bindings.previousSuggestion]
key = "up"

[bindings.dismissSuggestions]
key = "escape"
```

Key names are matched against the Node.js [keypress](https://nodejs.org/api/readline.html#readlineemitkeypresseventsstream-interface) events.

### Alias Expansion

Inshellisense supports expanding aliases for bash/zsh shells. You can enable alias expansion in your config file:

```toml
useAliases = true
```

### NerdFonts

If you are using a [NerdFont](https://www.nerdfonts.com/) patched font, you can enable the NerdFonts support in your config file:

```toml
useNerdFont = true
```

### Max Suggestions

You can change the maximum number of suggestions displayed in the autocomplete list at one time in your config file:


```toml
maxSuggestions = 10
```


## Unsupported Specs

Specs for the `az`, `gcloud`, & `aws` CLIs are not supported in inshellisense due to their large size.
