- App Links: Automatically create transactions with pre-filled data using app linking (documentation below)
A discussion/thread on App Links (example usage and how to harness the power of App Links) can be found at this issue: #127 (comment). App links allow direct navigation and automation of actions using application URLs. Some examples are below.
- Introduce iOS support (Cashew v5.3.5+400 and up)
- Breaking: Remove unsupported app link domain -
cashew://budget.app(Cashew v5.3.4+396 and up) - Support for more parameters documented under
Detailed Parameters(Cashew v5.2.9+358 and up) - Introduce Android and web support (Cashew v5.2.3+328 and up)
Ensure Cashew is installed on the device you are launching these URLs from.

Detailed Parameters
The following is a list of all and additional (not fully supported) parameters that can be passed in. They are ordered in terms of precedence, the parameters at the top will be parsed before the ones below. Therefore, overlapping fields will be proceeded by the first parameter.
Class: related parameters will have the same class.
Standalone parameters: only this parameter will be used, all other parameters will be ignored.
App link parsing can be found here.
| Class | Parameter | Description | Required | Default | Standalone |

]
}As an example:

"amount": "-100",
"notes": "This is a note",
"category": "Shopping"
},
{
"amount": "-150",
"notes": "This is a note 2"

}Don't forget to encode the JSON in the URL as JSON uses invalid URI characters. Once encoded, the output link would look something like:
If you get redirected to the website instead of the Cashew app, your device may not be correctly set up to open App Links. Ensure Cashew can open its respective app link. On your Android device head to your device settings, 'Default apps', 'Opening links' and ensure Cashew has permission to open from the domain cashewapp.web.app under 'Supported web addresses'. This may be disabled by default if you did not install a Google Play signed copy of Cashew (i.e. downloaded from GitHub). This is because Cashew now uses App Links which need to be verified as per Android 12+ requirements with an app's signature public key. Alternatively, you can use a redirect application such as LinkSheet which can manage which apps open when certain links are activated.
You can use ADB to test app links. For example
adb shell am start -a android.intent.action.VIEW -d "https://cashewapp.web.app/addTransaction?amount=-70\&title=Grocery%20Shopping\&date=2024-03-02\&category=Food\&subcategory=Groceries\¬es=Bought%20fruits%20and%20vegetables\&account=test"You can click links and open them with Cashew. See the example section above to test.

Walletshave been been renamed toAccountson the front-end but internally, the nameWalletis still used.
Objectiveshave been been renamed toGoalson the front-end but internally, the nameObjectivesis still used.
- Long term loans create a goal. However, the goals total is not used. Instead the total of the goal is calculated by totalling the proper polarity of transactions of the opposite type. For example, if it was a loan of 100$ lent out, the initial transaction would be 100$ of negative polarity (expense) and that would be the total of the goal. When a payment is made, it is made in the opposite (positive) polarity (income) and added to the total 'paid back'. We can easily find how much is remaining by taking the difference (or the addition including polarities).
