# Configurazione Avanzata

Nonostante Starship sia una shell versatile, a volte devi fare qualche modifica in più in `starship.toml` per ottenere alcune cose. Questa pagina descrive alcune tecniche di configurazione avanzate utilizzate in Starship.

> [!WARNING] The configurations in this section are subject to change in future releases of Starship.

## TransientPrompt su PowerShell

È possibile rimpiazzare il prompt precedente con una stringa di testo personalizzata. È utile nei casi in cui alcune informazioni sulla shell non ci servono. Per attivarlo, esegui `Enable-TransientPrompt` sulla shell. Per mantenerlo permanente, metti questa dichiarazione nel tuo `$PROFILE`. Può essere disattivata al volo con `Disable-TransientPrompt`.

Per impostazione predefinita, il simbolo predefinito prima dell'input sarà rimpiazzato con `>`. Per personalizzarlo, definisci una nuova funzione chiamata `Invoke-Starship-TransientFunction`. Ad esempio, per mostrare il modulo dei `character`, dovresti fare

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

Invoke-Expression (&starship init powershell)

Enable-TransientPrompt
```

## TransientPrompt e TransientRightPrompt in Cmd

È possibile rimpiazzare il prompt precedente con una stringa di testo personalizzata. È utile nei casi in cui alcune informazioni sulla shell non ci servono. Per attivarlo, esegui `clink set prompt.transient <value>` dove \<value\> può essere uno tra:

- `always`: sostituisce sempre il prompt precedente
- `same_dir`: sostituisce il prompt precedente solo se la directory di lavoro è la stessa
- `off`: non sostituisce il prompt (cioè disattiva la transizione)

Devi fare questo solo una volta. Fai le seguenti modifiche alla tua `starship.lua` per personalizzare ciò che viene visualizzato a sinistra e a destra:

- Per impostazione predefinita, il simbolo predefinito prima dell'input sarà rimpiazzato con `>`. 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. Ad esempio, per mostrare il modulo dei `character`, dovresti fare

```lua
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

```lua
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

È possibile rimpiazzare il prompt precedente con una stringa di testo personalizzata. È utile nei casi in cui alcune informazioni sulla shell non ci servono. 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`. Ad esempio, per mostrare il modulo dei `character`, dovresti fare

```fish
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

```fish
function starship_transient_rprompt_func
  starship module time
end
starship init fish | source
enable_transience
```

## TransientPrompt and TransientRightPrompt in Bash

The [Ble.sh](https://github.com/akinomyoga/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 the option `prompt_ps1_transient` has a non-empty \<value\>, the prompt specified by `PS1` is erased on leaving the current command line. If \<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 \<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 `~/.blerc` (or in `~/.config/blesh/init.sh`) 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

```bash
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

```bash
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

```lua
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

```lua
function starship_precmd_user_func(line)
  print("Executing: "..line)
end

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

## Comandi personalizzati di pre-prompt e pre-esecuzione per Bash

Bash non ha un framework preexec/precmd formale come la maggior parte delle altre shell. Per questo motivo, è difficile fornire hook completamente personalizzabile in `bash`. Tuttavia, Starship dà la limitata possibilità di inserire le tue funzioni nella procedura prompt-rendering:

- Per eseguire una funzione personalizzata a destra del prompt prima che venga disegnato, definisci una nuova funzione e assegna il suo nome a `starship_precmd_user_func`. Per esempio, per visualizzare l'icona di un razzo prima del prompt, si può usare il codice seguente

```bash
function blastoff(){
    echo "🚀"
}
starship_precmd_user_func="blastoff"
```

- Per eseguire una funzione personalizzata prima dell'esecuzione di un comando, è possibile utilizzare il meccanismo trappola [`DEBUG`](https://jichu4n.com/posts/debug-trap-and-prompt_command-in-bash/). Tuttavia, **devi** intrappolare il segnale DEBUG _prima di_ inizializzare Starship! Starship può preservare il valore trappola di DEBUG, ma se la trappola viene sovrascritta dopo l'avvio di Starship, alcune funzionalità non funzioneranno.

```bash
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`. Tuttavia, Starship dà la limitata possibilità di inserire le tue funzioni nella procedura prompt-rendering:

Create a function named `Invoke-Starship-PreCommand`

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

## Cambia il titolo della finestra

Alcune shell prompt cambieranno automaticamente il titolo della finestra (ad esempio per riflettere la directory di lavoro). Fish lo fa per impostazione predefinita. Starship does not do this, but it's fairly straightforward to add this functionality to `bash`, `zsh`, `cmd` or `powershell`.

Innanzitutto, bisogna definire una funzione per il cambio del titolo della finestra (identica sia per bash che zsh):

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

Puoi usare delle variabili per personalizzare questo titolo (`$USER`, `$HOSTNAME`, e `$PWD` sono le scelte più popolari).

In `bash`, impostare questa funzione per essere la precmd Starship function:

```bash
starship_precmd_user_func="set_win_title"
```

In `zsh`, aggiungi questo `precmd_functions` all'array:

```bash
precmd_functions+=(set_win_title)
```

Se ti piace il risultato, aggiungi queste righe al tuo file shell di configurazione (`~/.bashrc` o `~/.zshrc`) per renderlo permanente.

Ad esempio, se desideri visualizzare la directory corrente nel titolo della scheda del terminale, aggiungi la seguente snippet al tuo `~/.bashrc` or `~/.zshrc`:

```bash
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.

```lua
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`.

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

Invoke-Expression (&starship init powershell)
```

## 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](../config/#fill).

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

Note: The [Ble.sh](https://github.com/akinomyoga/ble.sh) framework v0.4 or higher should be installed in order to use right prompt in bash.

### Esempio

```toml
# ~/.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
```

## 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`

### Esempio

```toml
# ~/.config/starship.toml

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

## Statusline for Claude Code

Starship supports displaying a custom statusline when running inside Claude Code, Anthropic's CLI tool for interactive coding with Claude. This statusline provides real-time information about your Claude session, including the model being used, context window usage, and session costs.

For more information about the Claude Code statusline feature, see the [Claude Code statusline documentation](https://code.claude.com/docs/en/statusline).

### Setup

To use Starship as your Claude Code statusline:

1. Run `/statusline` in Claude Code and ask it to configure Starship, or manually add the following to your `.claude/settings.json`:

```json
{
  "statusLine": {
    "type": "command",
    "command": "starship statusline claude-code"
  }
}
```

2. Customize the statusline appearance in your `~/.config/starship.toml` (see [Configuration](#configuration) below)

### Overview

When invoked with `starship statusline claude-code`, Starship receives Claude Code session data via stdin and renders a statusline using a dedicated profile named `claude-code`.

The profile includes three specialized modules:

- `claude_model`: Displays the current Claude model being used
- `claude_context`: Shows context window usage with a visual gauge
- `claude_cost`: Displays session cost and statistics

The default profile format is:

```toml
[profiles]
claude-code = "$claude_model$git_branch$claude_context$claude_cost"
```

### Configurazione

You can customize the Claude Code statusline by modifying the `claude-code` profile and individual module configurations in your `~/.config/starship.toml`:

```toml
# ~/.config/starship.toml

# Customize the claude-code profile
[profiles]
claude-code = "$claude_model$claude_context$claude_cost"

# Configure individual modules
[claude_model]
format = "[$symbol$model]($style) "
symbol = "🤖 "
style = "bold blue"

[claude_context]
format = "[$gauge $percentage]($style) "
gauge_width = 10

[claude_cost]
format = "[$symbol$cost]($style) "
symbol = "💰 "
```

### Claude Model

The `claude_model` module displays the current Claude model being used in the session.

[claude_context]
format = "[$gauge]($style) "
gauge_width = 10
```

**Detailed token information**

```toml
# ~/.config/starship.toml

[claude_context]
format = "[$percentage ($input_tokens in / $output_tokens out)]($style) "
```

**Custom gauge symbols**

```toml
# ~/.config/starship.toml

[claude_context]
gauge_full_symbol = "▰"
gauge_partial_symbol = ""
gauge_empty_symbol = "▱"
gauge_width = 10
format = "[$gauge]($style) "
```

**Custom thresholds**

```toml
# ~/.config/starship.toml

[[claude_context.display]]
threshold = 0
style = "bold green"

[[claude_context.display]]
threshold = 50
style = "bold yellow"

[[claude_context.display]]
threshold = 75
style = "bold orange"

[[claude_context.display]]
threshold = 90
style = "bold red"
```

### Claude Cost

The `claude_cost` module displays the total cost of the current Claude Code session in USD. Like `claude_context`, it supports threshold-based styling.

#### Opzioni

| Opzione    | Default                            | Descrizione                         |

| `disabled` | `false`                            | Disables the `claude_cost` module.  |

##### Display

The `display` option is an array of objects that define cost thresholds and styles. The module uses the style from the highest matching threshold or hides the module if `hidden` is `true`.

| Opzione     | Default      | Descrizione                                                   |
| ----------- | ------------ | ------------------------------------------------------------- |
| `threshold` | `0.0`        | The minimum cost in USD to match this configuration           |
| `style`     | `bold green` | The value of `style` if this display configuration is matched |
| `hidden`    | `false`      | Hide this module if this configuration is matched.            |

**Default configuration:**

```toml
[[claude_cost.display]]
threshold = 0.0
hidden = true

[[claude_cost.display]]
threshold = 1.0
style = "bold yellow"

[[claude_cost.display]]
threshold = 5.0
style = "bold red"
```

## Stile delle Stringhe

Le stringhe di stile sono un elenco di parole, separate da spazi bianchi. Le parole non sono sensibili alle maiuscole (cioè `grassetto` e `BoLd` sono considerate la stessa stringa). Ogni parola può essere una delle seguenti:

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

dove `<color>` è un colore specifico (discusso in seguito). `fg:<color>` e `<color>` attualmente fanno la stessa cosa, anche se questo potrebbe cambiare in futuro. `<color>` can also be set to `prev_fg` or `prev_bg` which evaluates to the previous item's foreground or background color respectively if available or `none` otherwise. `inverted` scambia lo sfondo e i colori in primo piano. L'ordine delle parole nella stringa non conta.

Il token `none` sovrascrive tutti gli altri token in una stringa se non fa parte di uno specificatore `bg:`, così ad esempio `fg:red none fg:blue` creerà una stringa senza stile. `bg:none` imposta come colore di sfondo quello predefinito così `fg:red bg:none` è equivalente a `red` o `fg:red` e `bg:green fg:red bg:none` è equivalente a `fg:red` o `red`. Potrà diventare un errore usare `none` in combinazione con altri token in futuro.

Uno colore specifico può essere uno di questi:

- 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`).
- Un `#` seguito da un valore esadecimale a sei cifre. Questo specifica un [colore esagesimale in RGB](https://www.w3schools.com/colors/colors_hexadecimal.asp).
- Un numero compreso tra 0-255. Specifica un [codice colore ANSI a 8 bit](https://i.stack.imgur.com/KTSQa.png).

Se sono specificati più colori per il primo piano/sfondo, l'ultimo nella stringa avrà la priorità.

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](https://gitlab.com/gnachman/iterm2/-/issues/4564).
- `strikethrough` is not supported by the default macOS Terminal.app.
