## JJ
The `jj` module reflects the current status of your Jujutsu repository. It shows
different symbols and formats depending on the state of your work in progress,
including changes, commits, branch, and more.
The `jj` module is only shown when you're in a directory that is part of a
Jujutsu repository.
The default functionality includes displaying:
- current change id
- current commit id
::: warning
This module requires the Jujutsu command line tool to be installed and
accessible in your system's PATH for it to function correctly.
:::
### Options
| Option | Default | Description |
| ------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------- |
| `symbol` | `'🍐 '` | The string used before displaying the repository status. |
| `no_description_symbol` | `' 📝'` | Is displayed when change description is empty. |
| `divergent_symbol` | `' 💥'` | Is displayed when commit is in [divergent](https://github.com/martinvonz/jj/blob/main/docs/glossary.md#divergent-change) state. |
| `format` | `'\[$symbol[$change_id_prefix]($change_id_prefix_style)[$change_id_suffix]($change_id_suffix_style) [$commit_id_prefix]($commit_id_prefix_style)[$commit_id_suffix]($commit_id_suffix_style) on [$branch]($branch_style)$no_description_symbol$divergent_symbol\]'` | The format for rendering the module. `symbol`, `style`, and other variables can be included. |
| `disabled` | `false` | Disables the `jj` module. |
| `change_id_prefix_style` | `'purple'` | The style for uniq part of change id. |
| `change_id_suffix_style` | `'bright-black'` | The style for the rest of change id. |
| `commit_id_prefix_style` | `'blue'` | The style for unique part of commit hash. |
| `commit_id_suffix_style` | `'bright-black'` | The style for the rest of commit hash. |
| `truncation_length` | `8` | Truncates the commit and change id to `truncation_length` characters. |
| `branch_style` | `'purple'` | The style for the branch name. |
### Variables
```
[🍐 rnyynlop 811ca1a4 on push-rnyynlopprno*]
```
| Variable | Example | Description |
| ------------------ | --------- | ----------------------------------------------------------------- |
| `symbol` | `🍐` | Mirrors the value of option `symbol`. |
| `change_id_prefix` | `r` | Unique part of the change id, styled by `change_id_prefix_style`. |
| `change_id_suffix` | `nyynlop` | The rest of the change id, styled by `change_id_suffix_style`. |
| `commit_id_prefix` | `811` | Unique part of the commit id, styled by `commit_id_prefix_style`. |
| `commit_id_suffix` | `ca1a4` | The rest of the commit id, styled by `commit_id_suffix_style`. |
| `branch` | `master` | The current branch name. |
### Example
```toml
# ~/.config/starship.toml
[jj]
symbol = "🍐 "
style = "purple"
format = "\\[$symbol[$change_id_prefix]($change_id_prefix_style)[$change_id_suffix]($change_id_suffix_style) [$commit_id_prefix]($commit_id_prefix_style)[$commit_id_suffix]($commit_id_suffix_style) on [$branch]($branch_style)$no_description_symbol$divergent_symbol\\]"
disabled = false
change_id_prefix_style = "purple"
change_id_suffix_style = "bright-black"
commit_id_prefix_style = "blue"
commit_id_suffix_style = "bright-black"
truncation_length = 8
no_description_symbol = "📝"
divergent_symbol = "💥"
branch_style = "purple"
```
## Julia
The `julia` module shows the currently installed version of [Julia](https://julialang.org/).
