Installation
Transity is distributed as a JavaScript bundle and can therefore be installed via npm:
npm install --global transity
License
While Transity is licensed under the AGPL-3.0-or-later and can therefore be used free of charge, I hope you will acknowledge the work and effort it takes to maintain and improve this software and make a donation via my GitHub Support page.
If you find Transity valuable and/or use it regularly this should be a small nuisance for you, but it would mean the world for me! It would mean that I can spend more time on this project and bring it to the next level!
Thanks a lot for your support!
For including Transity in proprietary closed source products, please contact me!

Retrieving Data from Banks
Transity includes a few scripts located at ./scripts to automate a Chrome browser to download data. It supports downloading CSV files of all transactions and converting them to journal files and retrieving the current account balance:
Currently supported accounts for transactions:
Currently supported accounts for balances:
Contributions are very welcome!
Script Usage
node scripts/transactions/hypovereinsbank.js > transactions.yaml
This will prompt you for your credentials and afterwards automate a headless Chrome instance to download and convert the data.
Journal File Format
A minimal journal file is a YAML file with following format:
owner: annacommodities: - id: € name: Euro alias: - EUR note: Currency used in the European Union utc: '2017-04-02 19:33:53' entities: - id: anna name: Anna Smith utc: '2017-04-02 19:33:28' tags: - person accounts: - id: wallet name: Wallet note: Anna's black wallet utc: '2017-04-02 19:33:28' tags: - wallet - id: evil-corp name: Evil Corporation utc: '2017-04-02 19:33:28' note: The Evil Corporation in the United States of Evil tags: - company transactions: - title: Purchase of evil machine transfers: - utc: '2017-02-17' from: anna to: evil-corp amount: 50000 € - utc: '2017-02-17' from: evil-corp to: anna amount: 1 evil-machine
Plotting
By default all accounts are plotted.
To limit it to only a subsection use awk
to filter the output.
For example all transactions of Euro accounts:
transity gplot examples/journal.yaml \| awk '/^$/ || /(EOD|^set terminal)/ || /€/' \| gnuplot \| imgcat
Or all account balances of Euro accounts over time:
transity gplot-cumul examples/journal.yaml \| awk '/^$/ || /(EOD|^set terminal)/ || /€/' \| gnuplot \| imgcat
Import from Ledger CLI
Execute the included ledger2transity script:
./ledger2transity.sh examples/hledger.journal > transactions.csv
Convert transactions.csv
to YAML with e.g. browserling.com/tools/csv-to-yaml
Attention:
- Merge adjacent entries as each entry only debits / credits an account.
A transaction always involves 2 accounts (
from
andto
). (For expenses basically copy the ledger-account from the second entry into thefrom
field of the first entry) from
andto
might be reversed for income (depending on how thepayee
field was used)- Account names of Ledger-CLI are interpreted as tags Transity understands accounts as physical accounts
- The note is duplicated in the
tags
field. There is no way to get only the tags in Ledger-CLI 😔
FAQ
Why another plain text accounting tool?
Existing accounting tools are historically based on the notion of an account. You add money (debit) and you remove money (credit). (If this sounds backwards to you, read this explanation)
For example you get 50 € from your mum and buy some food for 20 €.
Account | Debit | Credit--------|---------|--------Wallet | 50.00 € |Wallet | | 20.00 €---------------------------
Simple, but also incomplete. Where did the money come from, where did it go? This led to double entry bookkeeping. Whenever you add some money to an account, you have to remove the same amount from another.
Account | Debit | Credit--------|---------|--------Wallet | 50.00 € |Mum | | 50.00 €Wallet | | 20.00 €Food | 20.00 € |---------------------------
But you must never forget a posting, because otherwise your account won't balance.
Account | Debit | Credit--------|---------|--------Wallet | 50.00 € |Mum | | 50.00 €Wallet | | 20.00 €---------------------------
Oops, where did the money go? 🤷
If this looks (and sounds) confusing or too complicated, you're not alone! It made sense in former times as this layout makes it easier to add up the amounts by hand, but not in times of computers.
So how can we simplify it? It's actually quite easy: We just have to model it in terms of transactions, and not accounts.
Amount | From | To-------|--------|--------50 € | Mum | Wallet20 € | Wallet | Food-------------------------
- Simple - No more confusing debit / credit / asset / liability mumbo jumbo
- Intuitive - Just like you would talk about it
- Safe - It's obvious if you forget to fill out a field
Together with some further changes it yields an easier to understand, more robust and more complete representation of accounting!
Why is it written in PureScript?
PureScript leverages strong static typing and can therefore give more guarantees about the functionality of the code than weakly typed or untyped languages (like JavaScript).
You wouldn't want your money to get lost in rounding errors or
be turned to undefined
, would you? 😉
Why is it not written in Haskell?
PureScript can also easily be used in the browser or get deployed as a cloud function as it simply compiles to JavaScript. With Haskell you'd have to use another language for a web frontend or quarrel with experimental stuff like GHCJS.
Comparison with Hledger
(H)ledger's transactions are a (balanced) group of account postings. Transity's transactions are a group of transfers between two accounts.
Syntax
Checkout the files hledger.journal and journal.yaml for similar transactions modeled in Hledger and in Transity.
There is a lot of ambiguity in the ledger journal format. Are you able to tell the difference between the 2 options?
2019-01-17 Bought food expenses:food $10 assets:cash ; vs 2019-01-17 Bought food assets:cash expenses:food $10
Also, it lacks some fields for more precise recording of which parties where involved.
- What food?
- Where did you buy it?
- Which supermarket?
2019-01-17 Bought food expenses:food $10 assets:cash
Reporting
hledger --file examples/hledger.journal balance# vs transity balance examples/journal.yaml
hledger --file examples/hledger.journal register# vs transity transactions examples/journal.yaml
hledger --file examples/hledger.journal register --output-format=csv# vs transity entries examples/journal.yaml
Missing features
- No support for precise timestamps (transactions only have an associated date)
- No first class support for Gnuplot (Check out Report Scripts for Ledger CLI with Gnuplot for some scripts)
Performance
Measured with hyperfine including 3 warmups on an early 2015 MacBook Pro.
For a journal file with around 2000 entries:
Transity:
Benchmark #1: transity balance journals/main.yaml Time (mean ± σ): 1.287 s ± 0.021 s [User: 1.790 s, System: 0.140 s] Range (min … max): 1.250 s … 1.324 s 10 runs
Hledger:
Benchmark #1: hledger -f test.ledger balance Time (mean ± σ): 409.6 ms ± 6.1 ms [User: 366.6 ms, System: 28.5 ms] Range (min … max): 398.8 ms … 417.6 ms 10 runs
Ledger:
Benchmark #1: ledger -f test.ledger balance Time (mean ± σ): 76.3 ms ± 9.1 ms [User: 62.7 ms, System: 9.4 ms] Range (min … max): 65.1 ms … 101.8 ms 28 runs
Ideas
Entry / Value Date
There are no separate fields for entry or value dates necessary. Simply use ISO 8601 time intervals to specify the duration of a transfer.
transactions: - id: '123456789' note: Deposit of savings transfers: - utc: 2018-01-04T12:00--05T22:10 from: john to: bank amount: 100 €
Syntax
This is a first concept for an alternative syntax for the YAML journal file:
2016-04-16 18:50:28#201356041 year registration of domain "example.org"john -> paypal : 9.95 €paypal -> namecheap : 10.69 $paypal -> icann : 0.18 $namecheap -> john : 1 Domain
