A new version of Amatino Swift has been released. 0.0.8 makes Amatino Swift CocoaPods compatible. You can now install Amatino by adding it to your Podfile:
pod 'Amatino', '>= 0.0.8'
The underlying library is unchanged. Here’s the full changelog:
Amatino.podspecreadme.md to reflect latest development of the libraryAmatino Swift 0.0.7 is now available! You can install it via Carthage or get the source code from GitHub. 0.0.7 is a major new release that adds significant capability. The powerful Tree, Position, and Performance objects are now available. Here’s the full change-log:
InternalLibraryError, which sneakily survived the error consolidation purge in 0.0.6Account.update() methodAccount.delete() methodAccount.deleteRecursively() methodTree classPosition classPerformance classNode protocolNode conforming TreeNode and PlaceholderNode classes (used by Tree, Position, and Performance)SessionCreateArguments & SessionAttributes into SessionBalanceRetrieveArguments into BalanceEntityObject protocol, reducing code complexity and duplication (does not affect public API)Trees present the entire chart of accounts of an Entity as a hierarchical object. Each node in the Tree summarises an Account, including an individual and recursive balances.
Each node is represented by an instance of a class conforming to the Node protocol. Two such classes existing: TreeNode and PlaceholderNode.
TreeNodes present summarised account data, including individual and recursive balances. PlaceholderNodes stand in for TreeNodes where the requesting User does not have read permissions for the Account in question. A PlaceholderNode still includes children, which may include TreeNodes if the User has permission to read from accounts further down the hierarchy.
Positions are generic representations of the accounting construct variously known as a balance sheet, statement of financial position, or something else depending on your jurisdiction. They include hierarchical representations of all asset, liability, and equity Accounts inside an Entity.
Like the Tree, each Account is represented by an instance of an object conforming to the Node protocol.
Performances are generic representations of the accounting construct variously known as an income statement, statement of financial performance, or comprehensive income statement, depending on your jurisdiction. They include hierarchical representations of all income and expense accounts inside an Entity.
Like the Tree and Position objects, each Account is represented by an instance of an object conforming to the Node protocol.
Account instances now feature .update() and delete() methods, which do what it says on the tin. Here’s an example of an update operation:
Delete operations require a bit of thought. Deleting an Account does not delete any Transactions with Entries party to that Account. As such, you must supply an Account you wish to transfer any Entries to upon deletion. Here’s an example:
0.0.8 will probably focus on units of account, i.e. GlobalUnits & CustomUnits. In particular, loading CustomUnits into an Entity so that you can denominate Transactions in whatever unit suits you.
Amatino Swift 0.0.6 has arrived! 0.0.6 makes lots of under the hood changes, the most important being to the error types emitted by the library. Here’s the changelog:
Transaction.update() methodTransaction.delete() methodsession and entity properties to Transaction(A side-effect of the addition of .update() and .delete())AmatinoErrorAmatinoError.Transaction, e.g. TransactionCreateArguments -> Transaction.CreateArgumentsAccountCreateArguments struct into Account as Account.CreateArgumentsAccount.create() & .retrieve() with Account.createMany() & .retrieveMany()Transaction to conform to a new internal EntityObject protocol, reducing code duplication (causes no changes to API)UrlParameters(:Entity:[UrlTarget]) entity label from entityWithTargets to entityObjectCore, AmatinoObjectError, and ConstraintError typesEntityCreateArguments struct into Entity.CreateArgumentsBefore 0.0.6, errors thrown by Amatino Swift were an absolute mess. There was AmatinoObjectError, ConstraintError, ResponseError, and even just plain old Error. Now, you can be sure that any error thrown by Amatino Swift will be of type AmatinoError.
AmatinoError provides an enum, Kind, off of which you can switch via AmatinoError.kind. For example, a Transaction.retrieve() request might yield a .notFound case when the Amatino API returns 404. You can get a verbose String description of an error by examining the AmatinoError.message property.
Some objects, such as Transaction, provide a superclass of AmatinoError called ConstraintError, which provides more detailed information about input constraint violations. For example, when you supply Transaction.create() with a description that is too long.
You can still handled these more verbose ConstraintError cases with a plain AmatinoError handler, as AmatinoError will flag them with the .constraintViolated case.
Sometimes you might which to change a Transaction after storing it. Perhaps an error was made, or underlying facts have changed. You can now do so using the update() instance method. Here’s an example:
You may also flat out delete a Transaction using the delete() instance method. Example:
Many Amatino Swift classes depend on a variety of ancillary structs to perform their work. For example, Transaction uses CreateArguments and UpdateArguments, as well as several internal types. These types were previously in their own files.
This arrangement was causing the Amatino Swift project to be a bit jumbled. Code completion when typing the start of an object name was also getting crowded. So, as a matter of preference, I’ve been moving all ancillary types into their relevant classes. For example, TransactionCreateArguments has become Transaction.CreateArguments.
This process started in 0.0.5, and is ongoing in 0.0.6. There are a few cases of the old style left, which I’ll probably get to in 0.0.7.
Enjoy!
A new version of Amatino Swift is available. Amatino Swift is library / framework that lets MacOS and iOS developers build double-entry accounting functionality into their applications. v0.0.3 is backwards compatible with v0.0.2, and makes the following changes:
Balance classRecursiveBalance classGlobalUnitList classTransaction.createMany() methodThese features build on v0.0.2’s progress toward making Amatino Swift easy to use. Where in the past you would need to manually encode and decode Data responses via the AmatinoAlpha class, you now have more expressive, clean, and simple syntax at your disposal.
Balance & RecursiveBalanceBalance and RecursiveBalance allow you to retrieve the balance of a particular account. In practice, that means the total of all debits & credits party to that account. A ‘recursive’ balance totals debits and credits for the target account, and any child accounts.
Balances can be retrieved for any combination of date and denomination. For example, you might have an account denominated in U.S. Dollars, but be interested in retrieving its balance in Euros.
Here’s an example of Balance.retrieve() in action:
RecursiveBalance.retrieve() syntax is identical.
Transaction.createMany()You can already create single Transactions using Transaction.create(). createMany()allows you to create up to ten Transactions in a single request. This dramatically reduces the round-trip latency suffered when you have more than one Transaction to insert.
createMany() is fed by lists of TransactionCreateArguments structs. Here’s an example:
GlobalUnitListv0.0.2 introduced the GlobalUnit class, without a way to list available Global Units! Enter GlobalUnitList, which will provide you with, you guessed it, a list of all available Global Units! Here’s how to use it:
There are 36 currencies available. You can look for a specific GlobalUnit in the GlobalUnitList with it’s unitWith(code:) method:
I’m in the process of creating Carthage and Cocoapods distributions for Amatino Swift. In the mean time, compiled libraries are available on GitHub. You are also most welcome to clone the repo and compile Amatino Swift yourself.
Many objects specified in the Amatino API HTTP documentation are not yet available in Amatino Swift. For example, account Ledgers. Further, available objects are missing some critical methods, like Transaction.delete().
Look out for v0.0.4 and onwards to add yet more capability to Amatino Swift. Let me know how you want Amatino Swift to develop on Twitter or on the forums. Sign up to the Development Newsletter to be notified when new versions of Amatino Swift are available.
