Ledger in Go

This is a project to parse and import transactions in a ledger file similar to the Ledger command line tool written in C++.

Simple Ledger file support

The ledger file this will parse is much simpler than the C++ tool.

Transaction Format:

<YYYY/MM/dd> <Payee description>
    <Account Name 1>    <Amount 1>
    .
    .
    .
    <Account Name N>    <Amount N>

The transaction must balance (the positive amounts must equal negative amounts). One of the account lines is allowed to have no amount. The amount necessary to balance the transaction will be added to that account for the transaction. Amounts must be decimal numbers with a negative(-) sign in front if necessary.

Example transaction:

2013/01/02 McDonald's #24233 HOUSTON TX
    Expenses:Dining Out:Fast Food        5.60
    Wallet:Cash

A ledger file is a list of transactions separated by a blank line.

A ledger file may include other ledger files using include <filepath>. The filepath is relative to the including file.

ledger

This will parse a ledger file into an array of Transaction structs. There is also a function get balances for all accounts in the ledger file.

GoDoc

cmd/ledger

A very simplistic version of Ledger. Supports "balance", "register", "print" and "stats" commands.

Example usage:

    ledger -f ledger.dat bal
    ledger -f ledger.dat bal Cash
    ledger -f ledger.dat reg
    ledger -f ledger.dat reg Food
    ledger -f ledger.dat print
    ledger -f ledger.dat stats

cmd/limport

Using an existing ledger as input to a bayesian classifier, it will attempt to classify an imported csv of transactions based on payee names and print them in a ledger file format.

Attempts to get payee, date, and amount based on headers in the csv file.

Example usage:

    limport -f ledger.dat discover discover-recent-transactions.csv

In the above example "discover" is the account search string to use to find the account that all transactions in the csv file should be applied too. The second account to use for each transaction will be picked based on the bayesian classification of the payee.

cmd/lweb

A website view of the ledger file. This program will show the account list, and ledger for a given account.

Reports available through the web interface are taken from a toml configuration file of the report configuration. See reports-sample.toml for examples.

Example usage:

    lweb -f ledger.dat -r reports.toml --port 8080

Incompatibilities

• C++ Ledger permits having amounts prefixed with $; Ledger in Go does not

• C++ Ledger permits an empty Payee Description; Ledger in Go does not
