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
```powershell
functionInvoke-Starship-TransientFunction{
&starshipmodulecharacter
}
Invoke-Expression(&starshipinitpowershell)
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
```lua
functionstarship_transient_prompt_func(prompt)
returnio.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
## 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
```fish
functionstarship_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
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
```lua
functionstarship_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
- To run a custom function right before a command runs, you can use the [`DEBUG` trap mechanism](https://jichu4n.com/posts/debug-trap-and-prompt_command-in-bash/). 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。
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`. 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：
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 does not do this, but it's fairly straightforward to add this functionality to `bash`, `zsh`, `cmd` or `powershell`.
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](/config/#fill).
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).
其中 `<color>` 是指定顏色用的（下面解釋）。 `fg:<color>` and `<color>` currently do the same thing, though this may change in the future. `inverted` swaps the background and foreground colors. 單詞在字串中的順序不重要。
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`. 未來可能會將 `none` 與其他符號一起使用的情形視為是一種錯誤。
- One of the standard terminal colors: `black`, `red`, `green`, `blue`, `yellow`, `purple`, `cyan`, `white`. You can optionally prefix these with `bright-` to get the bright version (e.g. `bright-white`).
