高级配置

Starship 功能繁多,有时您必须在编辑 <code>starship.toml 之外做更多工作才能实现某些效果。 此页面详细介绍了一些在 starship 中使用的高级配置技巧。

本节所述的配置内容可能随 Starship 未来版本的更新而改变。

在 Bash 中自定义预提示和预执行命令

Bash 并没有类似大多数其它 shell 的正式预执行/预命令框架。 因此,很难在 bash 中提供完全可自定义的 hook 机制。 然而Starship 确实能使您有限地在提示符渲染过程中插入自己的函数执行:

  • 若要在提示符显示之前运行自定义函数,需要定义此函数,然后将函数名赋值给 starship_reserved_user_func。 例如,要在提示符之前绘制一枚火箭,您应该写
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. 然而,您必须在捕捉 DEBUG 信号之前启动 Starship Starship 可以保留 DEBUG trap 的值,但如果该 trap 在 starship 启动后被覆盖,一些功能将会被破坏。
function blastoff(){
    echo "🚀"
}
trap blastoff DEBUG     # 启动 starship *之前* 设置 DEBUG trap
eval $(starship init bash)

更改窗口标题

Some shell prompts will automatically change the window title for you (e.g. to reflect your working directory). Fish 甚至默认会执行此功能。 Starship 没有实现此功能,但将这个功能添加到 bashzsh 是相当简单的。

首先,定义窗口标题更改函数(在 bash 和 zsh 中相同):

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

您可以使用变量来定制标题(常用的有 $USER$HOSTNAME$PWD)。

bash 中,设置此函数为 starship 预执行函数:

starship_precmd_user_func="set_win_title"

zsh中,将此函数添加到 reservmd_functions 列表:

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"

Enable Right Prompt

Some shells support a right prompt which renders on the same line as the input. Starship can set the content of the right prompt using the right_format option. Any module that can be used in format is also supported in right_format. The $all variable will only contain modules not explicitly used in either format or right_format.

Note: The right prompt is a single line following the input location. 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.

示例

# ~/.config/starship.toml

# A minimal left prompt
format = """$character"""

# move the rest of the prompt to the right
right_format = """$all"""

Produces a prompt like the following:

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

样式设定

Style strings are a list of words, separated by whitespace. The words are not case sensitive (i.e. bold and BoLd are considered the same string). Each word can be one of the following:

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

where <color> is a color specifier (discussed below). fg:<color> and <color> currently do the same thing, though this may change in the future. inverted swaps the background and foreground colors. The order of words in the string does not matter.

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. It may become an error to use none in conjunction with other tokens in the future.

A color specifier can be one of the following:

  • 标准终端颜色之一:blackredgreenblueyellowpurplecyanwhite。 您可以使用可选前缀 bright- 来获取明亮版本的颜色(例如,bright-white)。
  • 一个 # 后跟一个六位十六进制数。 这将指定一个 十六进制 RGB 颜色代码
  • 0-255 之间的数字。 这将指定一个 8 位 ANSI 颜色码

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