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.

$ touch ~/.config/starship.toml

All configuration for starship is done in this TOML file:

# 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 configuring 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.

"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 27
"underline bg:#bf5700" sets underlined text on a burnt orange background
"bold italic fg:purple" sets bold italic purple text
"" 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. Also, to get italic text, your terminal must support italics.

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	Configure the order in which the prompt module occurs.

Example

# ~/.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 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:

prompt_order = [
    "username",
    "hostname",
    "directory",
    "git_branch",
    "git_state",
    "git_status",
    "package",
    "nodejs",
    "ruby",
    "rust",
    "python",
    "golang",
    "java",
    "nix_shell",
    "cmd_duration",
    "line_break",
    "jobs",
    "battery",
    "time",
    "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.
`display`	link	Display threshold and style for the module.
`disabled`	`false`	Disables the `battery` module.

Example

# ~/.config/starship.toml

[battery]
full_symbol = "🔋"
charging_symbol = "⚡️"
discharging_symbol = "💀"

Battery Display

The display configuration option is used to define when the battery indicator should be shown (threshold) and what it looks like (style). If no display is provided. The default is as shown:

[[battery.display]]
threshold = 10
style = "bold red"

Options

The display option is an array of the following table.

Variable	Description
`threshold`	The upper bound for the display option.
`style`	The style used if the display option is in use.

Example

[[battery.display]]  # "bold red" style when capacity is between 0% and 10%
threshold = 10
style = "bold red"

[[battery.display]]  # "bold yellow" style when capacity is between 10% and 30%
threshold = 30
style = "bold yellow"

# when capacity is over 30%, the battery indicator will not be displayed

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

# ~/.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. Simply define the arrays preexec_functions and precmd_functions before running eval $(starship init $0), and then proceed as normal.
