進階設定

正因為 Starship 是一個多才多藝的 shell有時候你必須要做比修改 starship.toml 更多事情來讓它完成特定工作。 這個頁面說明了一些用於 Starship 的進階設定技巧。

::: warning

這個章節內的設定可能會隨著未來 Starship 的版本發行而變動。

:::

Bash 中的自定義預提示 (pre-prompt) 與預執行 (pre-execution) 指令

Bash 不像其他大多的 shell 具有正式的預執行/預指令框架。 因為這個原因,很難在 bash 中提供能完全自定義的 hook。 然而Starship 有提供給你有限的能力來插入你自己的函式到渲染提示字元的程序中:

  • 為了在畫出提示字元之前執行一個自定義的函式,請定義一個函式,並將它的名稱放入 starship_precmd_user_func 之中。 例如,為了要在提示字元前畫出一個火箭,你就要
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,你必須在初始化 Starship 之前 對 DEBUG 訊號設下trap Starship 可以保留 DEBUG trap 的數值,但是如果該 trap 在 starship 啟動後被被覆寫,某些功能會損壞。
function blastoff(){
    echo "🚀"
}
trap blastoff DEBUG     # 在 Starship 啟用*前*對 DEBUG 訊號設下 trap
eval $(starship init bash)

改變視窗標題

Some shell prompts will automatically change the window title for you (e.g. to reflect your working directory). Fish 甚至預設就會這樣做。 Starship 沒有幫你這樣做,但是可以用直覺的方式加入這個功能到 bashzsh 之中。

首先,定義一個改變視窗標題的函式(在 bash 與 zsh 之中都一樣):

function set_win_title(){
    echo -ne "\033]0; 你的標題在此 \007"
}

你可以利用變數來自定義這個標題($USER$HOSTNAME$PWD 是很受歡迎的選項)。

bash 中,將這個函式設定為 Starship 的預執行函式:

starship_precmd_user_func="set_win_title"

zsh 中,將這個函式加入 precmd_functions 陣列:

precmd_functions+=(set_win_title)

如果你喜歡這個結果,把這幾行加入你的 shell 設定檔中(~/.bashrc or ~/.zsrhc)來將此設為永久設定。

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.

範例

# ~/.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

風格字串

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
  • 斜體字
  • 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:

  • 任一個標準終端機顏色:blackredgreenblueyellowpurplecyanwhite。 你可以選擇性地加上前綴 bright- 來取得明亮版本的顏色(例如:bright-white)。
  • 一個 # 後面跟隨著六位數的十六進位數字。 這個指定了 RGB 十六進制色碼
  • 一個介於 0~255 之間的數字。 這個指定了 8-bit ANSI 色碼

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