# Configuration
::: tip
🔥 Configuration is currently being worked on.
Many new configuration options will be available in coming releases.
:::
To get started configuring starship, create the following file: `~/.config/starship.toml`.
```shell
$ touch ~/.config/starship.toml
```
All configuration for starship is done in this [TOML](https://github.com/toml-lang/toml) file:
```toml
# Don't print a new line at the start of the prompt
add_newline = false
# Replace the "❯" symbol in the prompt with "➜"
[character] # The name of the module we are confguring is "character"
symbol = "➜" # The "symbol" segment is being set to "➜"
# Disable the package module, hiding it from the prompt completely
[package]
disabled = true
```
### Terminology
**Module**: A component in the prompt giving information based on contextual information from your OS. For example, the "nodejs" module shows the version of NodeJS that is currently installed on your computer, if your current directory is a NodeJS project.
**Segment**: Smaller sub-components that compose a module. For example, the "symbol" segment in the "nodejs" module contains the character that is shown before the version number (⬢ by default).
Here is the representation of the node module. In the following example, "symbol" and "version"
are segments within it. Every module also has a prefix and suffix that are the default terminal color.
```
[prefix] [symbol] [version] [suffix]
"via " "⬢" "v10.4.1" ""
```
### Style Strings
Most modules in starship allow you to configure their display styles. This is done with an entry (usually called `style`) which is a string specifying the configuration. Here are some examples of style strings along with what they do. For details on the full syntax, consult the [advanced config guide](/advanced-config/).
- `"fg:green bg:blue"` sets green text on a blue background
- `"bg:blue fg:bright-green"` sets bright green text on a blue background
- `"bold fg:27"` sets bold text with [ANSI color](https://i.stack.imgur.com/KTSQa.png) 27
- `"underline bg:#bf5700"` sets underlined text on a burnt orange background
- `""` explicitly disables all styling
Note that what styling looks like will be controlled by your terminal emulator. For example, some terminal emulators will brighten the colors instead of bolding text, and some color themes use the same values for the normal and bright colors.
## Prompt
This is the list of prompt-wide configuration options.
### Options
| Variable | Default | Description |
| -------------- | ----------------------------- | ------------------------------------------------------ |
| `add_newline` | `true` | Add a new line before the start of the prompt. |
| `prompt_order` | [link](#default-prompt-order) | Configure the order in which the prompt module occurs. |
### Example
```toml
# ~/.config/starship.toml
# Disable the newline at the start of the prompt
add_newline = false
# Overwrite a default_prompt_order and use custom prompt_order
prompt_order=["rust","line_break","package","line_break","character"]
```
### Default prompt order
The `default_prompt_order` configuration option is used to define the order in which modules are shown in the prompt, if empty or no `prompt_order` is provided. The default is as shown:
```
default_prompt_order = [
"username",
"hostname",
"directory",
"git_branch",
"git_state",
"git_status",
"package",
"nodejs",
"ruby",
"rust",
"python",
"golang",
"nix_shell",
"cmd_duration",
"line_break",
"jobs",
"battery",
"character",
]
```
## Battery
The `battery` module shows how charged the device's battery is and its current charging status.
The module is only visible when the device's battery is below 10%.
### Options
| Variable | Default | Description |
| -------------------- | ------------ | ------------------------------------------------- |
| `full_symbol` | `"•"` | The symbol shown when the battery is full. |
| `charging_symbol` | `"⇡"` | The symbol shown when the battery is charging. |
| `discharging_symbol` | `"⇣"` | The symbol shown when the battery is discharging. |
| `style` | `"bold red"` | The style for the module. |
| `disabled` | `false` | Disables the `battery` module. |
### Example
```toml
# ~/.config/starship.toml
[battery]
full_symbol = "🔋"
charging_symbol = "⚡️"
discharging_symbol = "💀"
```
## Character
The `character` module shows a character (usually an arrow) beside where the text
is entered in your terminal.
The character will tell you whether the last command was successful or not. It
can do this in two ways: by changing color (red/green) or by changing its shape
(❯/✖). The latter will only be done if `use_symbol_for_status` is set to `true`.
### Options
| Variable | Default | Description |
| ----------------------- | -------------- | ----------------------------------------------------------------------------------- |
| `symbol` | `"❯"` | The symbol used before the text input in the prompt. |
| `error_symbol` | `"✖"` | The symbol used before text input if the previous command failed. |
| `use_symbol_for_status` | `false` | Indicate error status by changing the symbol. |
| `vicmd_symbol` | `"❮"` | The symbol used before the text input in the prompt if shell is in vim normal mode. |
| `style_success` | `"bold green"` | The style used if the last command was successful. |
| `style_failure` | `"bold red"` | The style used if the last command failed. |
| `disabled` | `false` | Disables the `character` module. |
### Example
```toml
# ~/.config/starship.toml
[character]
symbol = "➜"
error_symbol = "✗"
use_symbol_for_status = true
```
## Command Duration
The `cmd_duration` module shows how long the last command took to execute.
The module will be shown only if the command took longer than two seconds, or
the `min_time` config value, if it exists.
::: warning Do not hook the DEBUG trap in Bash
If you are running Starship in `bash`, do not hook the `DEBUG` trap after running
`eval $(starship init $0)`, or this module **will** break.
:::
Bash users who need preexec-like functionality can use
[rcaloras's bash_preexec framework](https://github.com/rcaloras/bash-preexec).
Simply define the arrays `preexec_functions` and `precmd_functions` before
running `eval $(starship init $0)`, and then proceed as normal.
### Options
| Variable | Default | Description |
| ---------- | --------------- | ----------------------------------- |
| `min_time` | `2` | Shortest duration to show time for. |
| `style` | `"bold yellow"` | The style for the module. |
| `disabled` | `false` | Disables the `cmd_duration` module. |
### Example
```toml
# ~/.config/starship.toml
[cmd_duration]
min_time = 4
```
## Directory
The `directory` module shows the path to your current directory, truncated to
three parent folders. Your directory will also be truncated to the root of the
git repo that you're currently in.
When using the fish style pwd option, instead of hiding the path that is
truncated, you will see a shortened name of each directory based on the number
you enable for the option.
For example, given `~/Dev/Nix/nixpkgs/pkgs` where `nixpkgs` is the repo root,
and the option set to `1`. You will now see `~/D/N/nixpkgs/pkgs`, whereas before
it would have been `nixpkgs/pkgs`.
### Options
| Variable | Default | Description |
| --------------------------- | ------------- | -------------------------------------------------------------------------------- |
| `truncation_length` | `3` | The number of parent folders that the current directory should be truncated to. |
| `truncate_to_repo` | `true` | Whether or not to truncate to the root of the git repo that you're currently in. |
| `fish_style_pwd_dir_length` | `0` | The number of characters to use when applying fish shell pwd path logic. |
| `style` | `"bold cyan"` | The style for the module. |
| `disabled` | `false` | Disables the `directory` module. |
### Example
```toml
# ~/.config/starship.toml
[directory]
truncation_length = 8

| `truncation_length` | `2^63 - 1` | Truncates a git branch to X graphemes |
| `truncation_symbol` | `"…"` | The symbol used to indicate a branch name was truncated. You can use "" for no symbol |
| `style` | `"bold purple"` | The style for the module. |
| `disabled` | `false` | Disables the `git_branch` module. |
### Example
```toml
# ~/.config/starship.toml
[git_branch]
symbol = "🌱 "
truncation_length = "4"
truncation_symbol = ""
```
## Git State
The `git_state` module will show in directories which are part of a git
repository, and where there is an operation in progress, such as: _REBASING_,

that information will be shown too.
### Options

| `style` | `"bold yellow"` | The style for the module. |
| `disabled` | `false` | Disables the `git_state` module. |
### Example
