The native interface includes a currency converter with real-time exchange rates from the Frankfurter API.
<Aside type="note">
The currency converter is only available in **native mode**. It is not available when using Fuzzel mode.
</Aside>
## Overview
Convert between currencies by typing an amount with a trigger character (default `$`) followed by target currency codes. Exchange rates are cached for one hour to minimize API requests.

## Usage
### Basic Syntax
```text
<trigger><amount> to <currency>
<trigger><amount><source> to <target>
```
### Examples
<Tabs>
<TabItem label="Default Currency">
```text
$10 to eur
# Converts 10 USD to EUR
```
</TabItem>
<TabItem label="Explicit Source">
```text
$50 gbp to usd
# Converts 50 GBP to USD
```
</TabItem>
<TabItem label="No Spaces">
```text
$100eur to jpy
# Converts 100 EUR to JPY
```
</TabItem>
<TabItem label="Custom Trigger">
```text
€10 to usd
# With trigger set to €
```
</TabItem>
</Tabs>
## Configuration
Configure the currency converter in your `raffi.yaml`:
```yaml raffi.yaml
addons:
currency:
enabled: true
trigger: "$"
default_currency: USD
currencies:
- USD
- EUR
- GBP
- JPY
- CAD
- AUD
```
### Configuration Options
**`enabled`** `boolean` (default: `true`)
Enable or disable the currency converter addon
**`trigger`** `string` (default: `$`)
Character that activates currency conversion. Common options: `$`, `€`, `£`, `¥`
**`default_currency`** `string` (default: `USD`)
Source currency when none is specified (e.g., `$10 to EUR` assumes USD)
**`currencies`** `array`
List of currency codes available for conversion. If omitted, all currencies from Frankfurter API are available.
### Custom Trigger
<Tabs>
<TabItem label="Dollar ($)">
```yaml
addons:
currency:
trigger: "$"
default_currency: USD
```
Usage: `$100 to eur`
</TabItem>
<TabItem label="Euro (€)">
```yaml
addons:
currency:
trigger: "€"
default_currency: EUR
```
Usage: `€100 to usd`
</TabItem>
<TabItem label="Pound (£)">
```yaml
addons:
currency:
trigger: "£"
default_currency: GBP
```
Usage: `£100 to eur`
</TabItem>
</Tabs>
### Supported Currencies
You can specify which currencies are available:
```yaml raffi.yaml
addons:
currency:
enabled: true
currencies:
- USD # US Dollar
- EUR # Euro
- GBP # British Pound
- JPY # Japanese Yen
- CAD # Canadian Dollar
- AUD # Australian Dollar
- CHF # Swiss Franc
- CNY # Chinese Yuan
- INR # Indian Rupee
- BRL # Brazilian Real
```
<Aside type="tip">
Leave the `currencies` field empty to allow conversion between all currencies supported by the Frankfurter API.
</Aside>
## Exchange Rate API
Raffi uses the [Frankfurter API](https://www.frankfurter.app/) for exchange rates:
- Free and open-source
- No API key required
- Updated daily with European Central Bank rates
- Rates are cached for 1 hour locally
### Cache Behavior
<Steps>
1. **First Request**
Fetches live rates from Frankfurter API
2. **Subsequent Requests**
Uses cached rates (valid for 1 hour)
3. **After 1 Hour**
Automatically fetches fresh rates on next conversion
</Steps>
## Conversion Patterns
<details>
<summary>Implicit Source Currency</summary>
When you don't specify a source currency, the `default_currency` is used:
```text
$10 to eur # 10 USD → EUR
$50 to gbp # 50 USD → GBP
$100 to jpy # 100 USD → JPY
```
</details>
<details>
<summary>Explicit Source Currency</summary>
Specify both source and target currencies:
```text
$10 usd to eur # 10 USD → EUR
$50 gbp to usd # 50 GBP → USD
$100 eur to jpy # 100 EUR → JPY
```
</details>
<details>
<summary>Compact Format</summary>
No spaces between amount and currency:
```text
$100eur to jpy # 100 EUR → JPY
$50gbp to usd # 50 GBP → USD
```
</details>
## Keyboard Shortcuts
- **Enter**: Copy conversion result to clipboard
- **Esc**: Clear input and return to normal mode
## Disable Currency Converter
To disable the currency converter:

```
## Requirements
<Aside type="caution">
Internet connection required for fetching exchange rates (cached for 1 hour)
</Aside>
<Aside type="note">
The converter requires `wl-copy` to copy results to clipboard
</Aside>
## Examples
```text
$1000 to eur # Planning trip to Europe
$99 usd to gbp # Compare prices
€500 to usd # Invoice conversion
$10000 to jpy # Currency exchange
```
## Troubleshooting
<details>
<summary>No conversion results</summary>
1. Check internet connection
2. Verify currency codes are correct (3-letter ISO codes)
3. Ensure `enabled: true` in config
4. Check that Frankfurter API is accessible
</details>
<details>
<summary>Wrong default currency</summary>
Set `default_currency` in your config:
```yaml
addons:
currency:
default_currency: EUR # Change from USD to EUR
```
</details>
<details>
<summary>Trigger not working</summary>
Make sure your trigger character doesn't conflict with other features:
```yaml
addons:
currency:
trigger: "$" # Or try "€", "£", etc.
```
