# Migrating to v0.45.0

Starship v0.45.0 is a release containing breaking changes, in preparation for the big v1.0.0. We have made some major changes around how configuration is done on the prompt, to allow for a greater degree of customization.

This guide is intended to walk you through the breaking changes.

## `prompt_order` has been replaced by a root-level `format`

Previously to v0.45.0, `prompt_order` would accept an array of module names in the order which they should be rendered by Starship.

Starship v0.45.0 instead accepts a `format` value, allowing for customization of the prompt outside of the modules themselves.

**Example pre-v0.45.0 configuration**

```toml
prompt_order = [
  "username",
  "hostname",
  "directory",
  "git_branch",
  "git_commit",
  "git_state",
  "git_status",
  "cmd_duration",
  "custom",
  "line_break",
  "jobs",
  "battery",
  "time",
  "character",
]
```

**Example v0.45.0 configuration**

```toml
format = """\
  $username\
  $hostname\
  $directory\
  $git_branch\
  $git_commit\
  $git_state\
  $git_status\
  $cmd_duration\
  $custom\
  $line_break\
  $jobs\
  $battery\
  $time\
  $character\
  """
```

## Module `prefix` and `suffix` have been replaced by `format`

Previously to v0.45.0, some modules would accept `prefix` and/or `suffix` in order to stylize the way that modules are rendered.

Starship v0.45.0 instead accepts a `format` value, allowing for further customization of how modules are rendered. Instead of defining a prefix and suffix for the context-based variables, the variables can now be substituted from within a format string, which represents the module's output.

**Example pre-v0.45.0 configuration**

```toml
[cmd_duration]
prefix = "took "
```

**Example v0.45.0 configuration**

```toml
[cmd_duration]
# $duration – The command duration (e.g. "15s")
# $style    – The default style of the module (e.g. "bold yellow")
format = "took [$duration]($style) "
```

### Affected Modules

#### Character

| Removed Property        | Replacement      |
| ----------------------- | ---------------- |
| `symbol`                | `success_symbol` |
| `use_symbol_for_status` | `error_symbol`   |
| `style_success`         | `success_symbol` |
| `style_failure`         | `error_symbol`   |

**Changes to the Default Configuration**

```diff
[character]
-- symbol = "❯"
-- error_symbol = "✖"
-- use_symbol_for_status = true
-- vicmd_symbol = "❮"
++ success_symbol = "[❯](bold green)"
++ error_symbol = "[❯](bold red)"
++ vicmd_symbol = "[❮](bold green)"
```

Previously, the `use_symbol_for_status` property was used to configure the prompt to show the `error_symbol` when the last command resulted in a non-zero status code.

With the release of v0.45.0, we now always use `error_symbol` after non-zero status codes, unifying `use_symbol_for_status` and `error_symbol` properties.

To configure the prompt to use the older `use_symbol_for_status = true` configuration, add the following to your config file:

```toml
[character]
error_symbol = "[✖](bold red)"
```

*Note:* The `character` element automatically adds a space after, so unlike the other `format` strings, we specifically do not add one in the above examples.

#### Command Duration

| Removed Property | Replacement |
| ---------------- | ----------- |
| `prefix`         | `format`    |

**Changes to the Default Configuration**

```diff
[cmd_duration]
-- prefix = "took "
++ format = "took [$duration]($style) "
```

#### Directory

| Removed Property | Replacement |
| ---------------- | ----------- |
| `prefix`         | `format`    |

**Changes to the Default Configuration**

```diff
[directory]
-- prefix = "in "
++ format = "[$path]($style)[$read_only]($read_only_style) "
```

#### Environment Variable

| Removed Property | Replacement |
| ---------------- | ----------- |
| `prefix`         | `format`    |
| `suffix`         | `format`    |

**Changes to the Default Configuration**

```diff
[env_var]
-- prefix = ""
-- suffix = ""
++ format = "with [$env_value]($style) "
```

#### Git Commit

| Removed Property | Replacement |
| ---------------- | ----------- |
| `prefix`         | `format`    |
| `suffix`         | `format`    |

**Changes to the Default Configuration**

```diff
[git_commit]
-- prefix = "("
-- suffix = ")"
++ format = "[\\($hash\\)]($style) "
```

#### Git Status

| Removed Property  | Replacement |
| ----------------- | ----------- |
| `prefix`          | `format`    |
| `suffix`          | `format`    |
| `show_sync_count` | `format`    |

**Changes to the Default Configuration**

```diff
[git_status]
-- prefix = "["
-- suffix = "]"
-- show_sync_count = false
++ format = "[\\[$all_status$ahead_behind\\]]($style)"
```

Previously, the `show_sync_count` property was used to configure the prompt to
show the number of commits the branch was ahead or behind the remote branch.

With the release of v0.45.0, this has been replaced with three separate properties, `ahead`, `behind`, and `diverged`.

To configure the prompt to use the older `show_sync_count = true`
configuration, set the following to your config file:

```toml
[git_status]
ahead = "⇡${count}"
diverged = "⇕⇡${ahead_count}⇣${behind_count}"
behind = "⇣${count}"
```

#### Hostname

| Removed Property | Replacement |
| ---------------- | ----------- |
| `prefix`         | `format`    |
| `suffix`         | `format`    |

**Changes to the Default Configuration**

```diff
[hostname]
-- prefix = ""
-- suffix = ""
++ format = "[$hostname]($style) in "
```

#### Singularity

| Removed Property | Replacement |
| ---------------- | ----------- |
| `label`          | `format`    |
| `prefix`         | `format`    |
| `suffix`         | `format`    |

**Changes to the Default Configuration**

```diff
[singularity]
-- prefix = ""
-- suffix = ""
++ format = "[$symbol\\[$env\\]]($style) "
```

#### Time

| Removed Property | Replacement   |
| ---------------- | ------------- |
| `format`         | `time_format` |

**Changes to the Default Configuration**

```diff
[time]
-- format = "🕙[ %T ]"
++ time_format = "%T"
++ format = "at 🕙[$time]($style) "
```

#### Custom Commands

| Removed Property | Replacement |
| ---------------- | ----------- |
| `prefix`         | `format`    |
| `suffix`         | `format`    |

**Changes to the Default Configuration**

```diff
[custom.example]
-- prefix = ""
-- suffix = ""
++ format = "[$symbol$output]($style) "
```
