고급 설정

While Starship is a versatile shell, sometimes you need to do more than edit starship.toml to get it to do certain things. This page details some of the more advanced configuration techniques used in starship.

::: warning

The configurations in this section are subject to change in future releases of Starship.

:::

TransientPrompt in PowerShell

It is possible to replace the previous-printed prompt with a custom string. This is useful in cases where all the prompt information is not always needed. To enable this, run Enable-TransientPrompt in the shell session. To make it permanent, put this statement in your $PROFILE. Transience can be disabled on-the-fly with Disable-TransientPrompt.

By default, the left side of input gets replaced with >. To customize this, define a new function called Invoke-Starship-TransientFunction. For example, to display Starship's character module here, you would do

function Invoke-Starship-TransientFunction {
  &starship module character
}

Invoke-Expression (&starship init powershell)

Enable-TransientPrompt

TransientPrompt and TransientRightPrompt in Cmd

Clink allows you to replace the previous-printed prompt with custom strings. This is useful in cases where all the prompt information is not always needed. To enable this, run clink set prompt.transient <value> where <value> can be one of:

  • always: always replace the previous prompt
  • same_dir: replace the previous prompt only if the working directory is same
  • off: do not replace the prompt (i.e. turn off transience)

You need to do this only once. Make the following changes to your starship.lua to customize what gets displayed on the left and on the right:

  • By default, the left side of input gets replaced with >. To customize this, define a new function called starship_transient_prompt_func. This function receives the current prompt as a string that you can utilize. For example, to display Starship's character module here, you would do
function starship_transient_prompt_func(prompt)
  return io.popen("starship module character"
    .." --keymap="..rl.getvariable('keymap')
  ):read("*a")
end
load(io.popen('starship init cmd'):read("*a"))()
  • By default, the right side of input is empty. To customize this, define a new function called starship_transient_rprompt_func. This function receives the current prompt as a string that you can utilize. For example, to display the time at which the last command was started here, you would do
function starship_transient_rprompt_func(prompt)
  return io.popen("starship module time"):read("*a")
end
load(io.popen('starship init cmd'):read("*a"))()

TransientPrompt and TransientRightPrompt in Fish

It is possible to replace the previous-printed prompt with a custom string. This is useful in cases where all the prompt information is not always needed. To enable this, run enable_transience in the shell session. To make it permanent, put this statement in your ~/.config/fish/config.fish. Transience can be disabled on-the-fly with disable_transience.

Note that in case of Fish, the transient prompt is only printed if the commandline is non-empty, and syntactically correct.

  • By default, the left side of input gets replaced with a bold-green ❯. To customize this, define a new function called starship_transient_prompt_func. For example, to display Starship's character module here, you would do
function starship_transient_prompt_func
  starship module character
end
starship init fish | source
enable_transience
  • By default, the right side of input is empty. To customize this, define a new function called starship_transient_rprompt_func. For example, to display the time at which the last command was started here, you would do
function starship_transient_rprompt_func
  starship module time
end
starship init fish | source
enable_transience

TransientPrompt and TransientRightPrompt in Bash

The Ble.sh framework at v0.4 or higher allows you to replace the previous-printed prompt with custom strings. This is useful in cases where all the prompt information is not always needed. To enable this, put this in ~/.bashrc bleopt prompt_ps1_transient=<value>:

The <value> here is a colon-separated list of always, same-dir and trim. When prompt_ps1_final is empty and this option has a non-empty value, the prompt specified by PS1 is erased on leaving the current command line. If the value contains a field trim, only the last line of multiline PS1 is preserved and the other lines are erased. Otherwise, the command line will be redrawn as if PS1= is specified. When a field same-dir is contained in the value and the current working directory is different from the final directory of the previous command line, this option prompt_ps1_transient is ignored.

Make the following changes to your ~/.bashrc to customize what gets displayed on the left and on the right:

  • To customize what the left side of input gets replaced with, configure the prompt_ps1_final Ble.sh option. For example, to display Starship's character module here, you would do
bleopt prompt_ps1_final="$(starship module character)"
  • To customize what the right side of input gets replaced with, configure the prompt_rps1_final Ble.sh option. For example, to display the time at which the last command was started here, you would do
bleopt prompt_rps1_final="$(starship module time)"

Custom pre-prompt and pre-execution Commands in Cmd

Clink provides extremely flexible APIs to run pre-prompt and pre-exec commands in Cmd shell. It is fairly simple to use with Starship. Make the following changes to your starship.lua file as per your requirements:

  • To run a custom function right before the prompt is drawn, define a new function called starship_preprompt_user_func. This function receives the current prompt as a string that you can utilize. For example, to draw a rocket before the prompt, you would do
function starship_preprompt_user_func(prompt)
  print("🚀")
end

load(io.popen('starship init cmd'):read("*a"))()
  • To run a custom function right before a command is executed, define a new function called starship_precmd_user_func. This function receives the current commandline as a string that you can utilize. For example, to print the command that's about to be executed, you would do
function starship_precmd_user_func(line)
  print("Executing: "..line)
end

load(io.popen('starship init cmd'):read("*a"))()

Custom pre-prompt and pre-execution Commands in Bash

Bash does not have a formal preexec/precmd framework like most other shells. Because of this, it is difficult to provide fully customizable hooks in bash. However, Starship does give you limited ability to insert your own functions into the prompt-rendering procedure:

  • To run a custom function right before the prompt is drawn, define a new function and then assign its name to starship_precmd_user_func. For example, to draw a rocket before the prompt, you would do
function blastoff(){
    echo "🚀"
}
starship_precmd_user_func="blastoff"
  • To run a custom function right before a command runs, you can use the DEBUG trap mechanism. However, you must trap the DEBUG signal before initializing Starship! Starship can preserve the value of the DEBUG trap, but if the trap is overwritten after starship starts up, some functionality will break.
function blastoff(){
    echo "🚀"
}
trap blastoff DEBUG     # Trap DEBUG *before* running starship
set -o functrace
eval $(starship init bash)
set +o functrace

Custom pre-prompt and pre-execution Commands in PowerShell

PowerShell does not have a formal preexec/precmd framework like most other shells. Because of this, it is difficult to provide fully customizable hooks in powershell. However, Starship does give you limited ability to insert your own functions into the prompt-rendering procedure:

Create a function named Invoke-Starship-PreCommand

function Invoke-Starship-PreCommand {
    $host.ui.Write("🚀")
}

Change Window Title

Some shell prompts will automatically change the window title for you (e.g. to reflect your working directory). Fish even does it by default. Starship does not do this, but it's fairly straightforward to add this functionality to bash, zsh, cmd or powershell.

First, define a window title change function (identical in bash and zsh):

function set_win_title(){
    echo -ne "\033]0; YOUR_WINDOW_TITLE_HERE \007"
}

You can use variables to customize this title ($USER, $HOSTNAME, and $PWD are popular choices).

In bash, set this function to be the precmd starship function:

starship_precmd_user_func="set_win_title"

In zsh, add this to the precmd_functions array:

precmd_functions+=(set_win_title)

If you like the result, add these lines to your shell configuration file (~/.bashrc or ~/.zshrc) to make it permanent.

For example, if you want to display your current directory in your terminal tab title, add the following snippet to your ~/.bashrc or ~/.zshrc:

function set_win_title(){
    echo -ne "\033]0; $(basename "$PWD") \007"
}
starship_precmd_user_func="set_win_title"

For Cmd, you can change the window title using the starship_preprompt_user_func function.

function starship_preprompt_user_func(prompt)
  console.settitle(os.getenv('USERNAME').."@"..os.getenv('COMPUTERNAME')..": "..os.getcwd())
end

load(io.popen('starship init cmd'):read("*a"))()

You can also set a similar output with PowerShell by creating a function named Invoke-Starship-PreCommand.

# edit $PROFILE
function Invoke-Starship-PreCommand {
  $host.ui.RawUI.WindowTitle = "$env:USERNAME@$env:COMPUTERNAME`: $pwd `a"
}

Invoke-Expression (&starship init powershell)

오른쪽 프롬프트 활성화

일부 셸은 입력과 같은 줄에 렌더링되는 오른쪽 프롬프트를 지원합니다. Starship에서는 right_format 옵션을 사용하여 오른쪽 프롬프트의 내용을 설정할 수 있습니다. format에서 사용할 수 있는 모든 모듈은 right_format에서도 지원됩니다. $all 변수는 format 또는 right_format에서 명시적으로 사용하지 않는 모듈만 포함합니다.

알림: 오른쪽 프롬프트는 입력 위치에 따라 한 줄로 표시됩니다. To right align modules above the input line in a multi-line prompt, see the fill module.

right_format is currently supported for the following shells: elvish, fish, zsh, xonsh, cmd, nushell, bash.

Note: The Ble.sh framework v0.4 or higher should be installed in order to use right prompt in bash.

예시

# ~/.config/starship.toml

# 간결한 왼쪽 프롬프트
format = """$character"""

# 프롬프트의 나머지를 오른쪽으로 옮기기
right_format = """$all"""

위 설정은 아래와 같은 프롬프트를 출력합니다:

▶                                   starship on  rprompt [!] is 📦 v0.57.0 via 🦀 v1.54.0 took 17s

Continuation Prompt

Some shells support a continuation prompt along with the normal prompt. This prompt is rendered instead of the normal prompt when the user has entered an incomplete statement (such as a single left parenthesis or quote).

Starship can set the continuation prompt using the continuation_prompt option. The default prompt is '[∙](bright-black) '.

Note: continuation_prompt should be set to a literal string without any variables.

Note: Continuation prompts are only available in the following shells:

  • bash
  • zsh
  • Powershell

예시

# ~/.config/starship.toml

# A continuation prompt that displays two filled in arrows
continuation_prompt = '▶▶ '

스타일 문자열

스타일 문자열은 공백으로 구분된 단어 목록입니다. 단어는 대소문자를 구분하지 않습니다 (즉, bold와 BoLd는 동일한 문자열로 간주됩니다). 각 단어는 다음 중 하나가 될 수 있습니다:

  • bold
  • italic
  • underline
  • dimmed
  • inverted
  • blink
  • hidden
  • strikethrough
  • bg:<color>
  • fg:<color>
  • <color>
  • none

<color> 부분은 색상 지정자입니다 (아래에 후술). 현재, fg:<color> 와 <color>는 동일한 동작을 하지만 차후에 바뀔 수 있습니다. inverted는 배경 색과 전경 색을 서로 바꿉니다. 문자열의 단어 순서는 중요하지 않습니다.

The none token overrides all other tokens in a string if it is not part of a bg: specifier, so that e.g. fg:red none fg:blue will still create a string with no styling. bg:none sets the background to the default color so fg:red bg:none is equivalent to red or fg:red and bg:green fg:red bg:none is also equivalent to fg:red or red. 향후 다른 토큰과 함께 none을 사용하는 것은 오류가 발생할 수 있습니다.

색상 지정자는 다음 중 하나가 될 수 있습니다:

  • 표준 터미널 색상: black, red, green, blue, yellow, purple, cyan, white. 앞에 bright-를 붙여 밝게 만들 수도 있습니다 (예시: bright-white).
  • # 다음의 여섯 자리 16진수 숫자. 이는 RGB 색상 16진수 코드입니다.
  • 0~255 사이의 숫자. 이는 8비트 ANSI 색상 코드입니다.

If multiple colors are specified for foreground/background, the last one in the string will take priority.

Not every style string will be displayed correctly by every terminal. In particular, the following known quirks exist:

  • Many terminals disable support for blink by default
  • hidden is not supported on iTerm.
  • strikethrough is not supported by the default macOS Terminal.app
