Ledger.js is inspired by it's namesake ledger and seeks to replicate the functionality in Javascript for use in Node.js and browser projects.
{Journal, Transaction, Posting} = require 'ledger.js'
revocup = new Transaction("Revocup")
revocup.postings.push new Posting "$4", "Expenses:Beverages:Coffee"
newEgg.postings.push new Posting "$-4", "Assets:Checking"
newEgg = new Transaction("Revocup")
newEgg.postings.push new Posting "$17", "Expenses:Computers"
newEgg.postings.push new Posting "$-17", "Assets:Checking"
ledger = new Journal
ledger.expenses.push revocup
ledger.expenses.push newEgg
# using double-entry accounting, we should see $0
ledger.total()
#=> 0.00
eliteComics = new Transaction("Elite Comics", new Date(2012, 7, 3))
eliteComics.postings.push new Posting "$10.57", "Expenses:Comics"
eliteComics.postings.push new Posting "$-10.57", "Assets:Checking"
ledger.expenses.push eliteComics
ledger.toString()
#=> 7/28 - $4 at Revocup
7/28 - $17 at New Egg
7/3 - $10.57 at Elite ComicsThe goal is to replicate all, or as much as possible, the features found in ledger. Ledger is super well though out, and has a lot of stuff goin on, so this process will take time. As of this writing (v0.1.4) the feature set is very limited.
I am writing this library for use in a digital personal assistant. The bot keeps track of my daily expenses, and then I do my books every night. Please open up an issue for any features you'd like to see, as long as it has bearing in ledger I'm sure I'll put it in.
