Inspired by ledger-cli, goledger is a re-write of command line ledger in golang, with the stated goals.
- Keeping it command line friendly, whether or not GUI / web interface are available.
- Defaults to Locale en_IN, until the tool becomes smart enough to handle locale specific details automatically.
- Targeted for personal, small and medium enterprises.
- Keep to the spirit of ledger-cli as much as possible.
Credit the giver debit the receiver.Commodity, based accounting, where currency is also a commodity.Account, holding one or more commodities.Posting, commodities can be posted to an account. Posting can be debit posting or credit posting, based on whether the account is the source account (credit the giver) or target account (debit the receiver)Transaction, involving 2 or more postings, where the sum of credit postings should balance out the sum of debit postings.
Once comfortable with above concepts, we can start book-keeping with ledger.
Book-keeping starts with the journal file, typically ending with .ldg. A
ledger file can contain directives (sometimes called as declarations) or
transaction entries.
There can be any number of directives and any number of transaction entries.
Transactions have the following format:
2011/03/15 Whole Food Market
Expenses:Groceries 75.00
Assets:Checking -75
line1: Date and Payee
line2: Accountname, Amount
line3: Accountname, Amount
- Each transaction is associated with a date, and it is always advised to enter transaction with older date before and newer date after.
- Payee gives a name to the transaction, other than that no special meaning is attached to it.
- Posting with positive amount are treated as debit transaction, and the posting's account is called target account.
- Posting with negative amount are treated as credit transaction, and the posting's account is called source account.
To begin with, ledger tool expects one or more journal files to process. As mentioned earlier, a journal file typically contains directives and transactions. The format of journal file is plain text.
$ goledger -f journal.ldgTo process more than one journal files, supply them as
-f journal1.ldg,journal2.lsg. Even if the journals are not in time order
or transactions within a journal file is not in time order, goledger will
sort them in time order before applying them.
Including journal files
If several journal files need to be processed, it is easier to create a new file and include other journal files within. For example consolidate.ldg can have:
include journal1.ldg
include journal2.ldg
Account-name
There are some conventions used in account naming. Account names can be composed of any character except:
- Double spaces and tabs
- Mathematical and logical operators:
-+*/^&|= - Bracketing characters:
<>[](){} - The at symbol:
@ - semicolon:
;
Commodity-name
Commodity can appear before or after the amount, and may or may not be separated from it by a space. Most characters are allowed in a commodity name, except for the following:
- Any kind of white-space
- Numerical digits
- Punctuation:
.,;:?! - Mathematical and logical operators:
-+*/^&|= - Bracketing characters:
<>[](){} - The at symbol:
@
While the basic concept of accounting is not more that what is stated above, there are endless variations stipulated by accounting standards and conventions. Sometimes we may need different view of accounts for the same set of transactions. For example, let us take accrual accounting:
Accrual accounting
Cash (or commodities) are physical and to get a realistic picture of our accounts we book transactions that has already taken place physically. Now, we will look at three different scenarios demanding three different flavours of realism.
Scenario1: Income Tax filing
At least in India income tax department expects us to accrue all interest that are receivable on Bank deposits, as income, and pay tax. Although we might not have received the interest until the deposit matures. How to book this in goledger:
2016/Jun/21 FD savings ; Deposit for 1 year
Asset:FD 10000
Asset:CurrentAccount
2017/Mar/31 Accrued interest on Bank FD
Income:Interest:Receivable 800
Income:FD-Interest
2017/Jun/22 FD Matures
Asset:CurrentAccount 11000
Income:Interest:Receivable -800
Income:FD-Interest -200
Asset:FD -10000
Scenario2: Distress sale of company
When a company is under distress and a valuation is to be done to attract potential buyers, it is normally expected that buyer would ask us to discount Receivables but include Payables.
Scenario3: Brokerage houses
If book keeping is done for a brokerage house, which buy commodity and sell them later, most often the actual payment will be deferred until actual sale has happened. For them, accrual accounting might have to be totally skipped while generating a report on operating-cost.
As evident in above case, such variations are endless and hence, goledger
doesn't try to be smart about them. Just Credit the giver and debit the receiver. If a particular feature or a nicety is required in booking
a transaction or in generating a report, please file an issue and let us
see whether or how to take it forward.
Balance
The primary objective of consolidating all transactions is to make sure that
all debits and all credits balance out each other. So there is a balance
command.
$ goledger -f journal.ldg balanceIt is also possible to filter out accounts listed in a balance report, for
instance the below command will list only accounts containing Asset::
$ goledger -f journal.ldg balance Asset:Passbook
A passbook implies transaction between one account, let us call this as third party account, and all other accounts. The third party many not be interested in all the other accounts, from his/her point of view the contra posting in a transaction to all the other accounts are irrelevant. In such cases we can generate a passbook and give it to them:
$ goledger -f journal.ldg passbook JohnJohn is the third party for whom the passbook is generated.
equity
One way to organize journal file add all transactions in the same file year
after year. But this can quickly get large and can become messy, it can also
take goledger more time to process all the entries. To avoid this, we can
split journals into separate files one for each financial-year. For this,
equity can be very handy, which can report the year end balance as a
transaction for next year's Opening balance.
goledger -f journal-2015.ldg equity > journal-2016.ldgNow this come with the cost of information loss, that is, while processing
the journal file for 2016, journal-2016.ldg goledger can't generate
interesting reports from earlier transactions. To work around this:
goledger -f journal-2015.ldg,journal-2016.ldg -stitch registeruse the -stitch that can skip all transactions with Payee as Opening balance.
There are plans to package ledger for different platforms, like windows, ubuntu, mac, raspberry-pi, debian etc.. Until then, goledger can be obtained via golang-tools. For mac or linux users, install Golang, and:
$ go get github.com/tn47/goledger
$ cd tn47/goledger
$ make test # sanity test.
$ make installIt is surprisingly easy!!
- Account name should start with at least 2 character
- Hard spaces (2 or more consecutive spaces or a single tab-space) have special meaning in ledger format. So avoid them in account names.
- ledger rewrite in haskell
- ledger rewrite on JVM
- ledger rewrite in scala
- ledger-cli, it is worth spending time reading upon the ledger specification.
- Pick an issue, or create an new issue. Provide adequate documentation for the issue.
- Assign the issue or get it assigned.
- Work on the code, once finished, raise a pull request.
- Goledger is written in golang, hence expected to follow the global guidelines for writing go programs.
- If the changeset is more than few lines, please generate a report card.
Happy Accounting !!
