libledger

Library for interacting with Ledger files.

libledger provides Ledger::Entry, which is a transaction, and Ledger::Journal, a list of transactions.

To create a new entry:

require 'libledger'
require 'date'

entry = Ledger::Entry.new(
  name: 'Delicious Chipotle Burrito',
  state: :cleared,
  date: Date.today,
  actions: [
    { name: 'Expenses:Burritos', amount: '$6.89' },
    { name: 'Assets:visa' }
  ]
)

# This will print the entry in ledger format
puts entry

To read an entry, call Ledger::Entry.from_lines(lines). lines should be an array of strings, which are the lines of a ledger journal for that transaction.

To read a full journal, use Ledger::Journal.from_file(file), where file should be a path to the journal file. If you have multiple files, Ledger::Journal.from_files(files) accepts an array of paths.

To create a journal, use Ledger::Journal.new(entries: array_of_entries).

The output of .to_s on a Journal (which is called if you do puts my_journal is the ledger text file format for its transactions.
