Migrating from hledger

This guide helps you migrate from hledger to rustledger's beancount format.

Key Differences

hledger uses a format compatible with ledger-cli. Beancount has stricter syntax requirements.

Syntax Comparison

Feature	hledger	Beancount
File extension	.journal	.beancount
Account opens	Optional	Required
Payee format	After date	In quotes
Amounts	Can auto-balance	Must balance
Comments	; or #	;
Directives	account, commodity	open, commodity

Example Comparison

hledger:

2024-01-15 Coffee Shop
    expenses:food:coffee     $5.00
    assets:cash

2024-01-15 balance assets:checking  = $1234.56

Beancount:

2020-01-01 open Assets:Cash              USD
2020-01-01 open Assets:Checking          USD
2020-01-01 open Expenses:Food:Coffee

2024-01-15 * "Coffee Shop"
  Expenses:Food:Coffee     5.00 USD
  Assets:Cash             -5.00 USD

2024-01-15 balance Assets:Checking  1234.56 USD

Migration Steps

1. Export from hledger

hledger print -f main.journal > export.journal

2. Convert Account Names

Beancount accounts must be Title:Case:

expenses:food:coffee  →  Expenses:Food:Coffee
assets:checking       →  Assets:Checking

Script to help:

# Convert account names to Title Case
sed -E 's/([a-z]+:)/\u\1/g' export.journal

3. Generate Account Opens

hledger accounts -f main.journal | while read account; do
  # Convert to Title Case
  titled=$(echo "$account" | sed 's/\(^\|:\)\([a-z]\)/\1\u\2/g')
  echo "2020-01-01 open $titled"
done > accounts.beancount

4. Convert Transactions

Key changes:

1. Add quotes around payees

   2024-01-15 Coffee Shop
   →
   2024-01-15 * "Coffee Shop"

2. Convert commodities

   $5.00  →  5.00 USD
   €10    →  10.00 EUR

3. Add explicit balance

   expenses:food    $5.00
   assets:cash
   →
   Expenses:Food     5.00 USD
   Assets:Cash      -5.00 USD

4. Convert balance assertions

   2024-01-15 balance assets:checking  = $1234.56
   →
   2024-01-15 balance Assets:Checking  1234.56 USD

5. Validate

rledger check ledger.beancount

Command Mapping

hledger	rustledger
hledger bal	rledger report balances
hledger reg	rledger report journal
hledger print	rledger format
hledger accounts	rledger report accounts
hledger bs	rledger report balsheet
hledger is	rledger report income
hledger check	rledger check

Query Differences

hledger uses its own query syntax; rustledger uses BQL:

hledger:

hledger reg expenses:food date:2024

rustledger (BQL):

rledger query ledger.beancount \
  "SELECT date, narration, position
   WHERE account ~ 'Expenses:Food' AND year(date) = 2024"

Shell Aliases

Recreate hledger-style commands:

# ~/.bashrc
export LEDGER_FILE="$HOME/finances/ledger.beancount"

alias bal='rledger report "$LEDGER_FILE" balances'
alias bs='rledger report "$LEDGER_FILE" balsheet'
alias is='rledger report "$LEDGER_FILE" income'

reg() {
  if [ -n "$1" ]; then
    rledger report "$LEDGER_FILE" journal -a "$1"
  else
    rledger report "$LEDGER_FILE" journal
  fi
}

hledger Features

Supported Differently

hledger Feature	Beancount Equivalent
account directive	open directive
Lowercase accounts	Title Case required
Auto-balance	Explicit amounts
Balance assertions	balance directive
include	include
Tags	Tags and links

Not Supported

Feature	Alternative
Virtual accounts	Use regular accounts with tags
Periodic transactions	Manual entry or scripts
alias directive	None (use search-replace)
CSV rules	rledger extract with config

Beancount Extras

Features available in beancount but not hledger:

• Booking methods: FIFO, LIFO, STRICT, etc. for investments
• Cost basis tracking: Built-in capital gains handling
• Plugins: Validation and transformation plugins
• BQL: SQL-like query language

Conversion Script

Basic conversion script:

#!/usr/bin/env python3
"""Convert hledger journal to beancount format."""

import re
import sys

def title_case(account):
    """Convert account:name to Account:Name."""
    return ':'.join(word.title() for word in account.split(':'))

def convert_amount(amount):
    """Convert $5.00 to 5.00 USD."""
    match = re.match(r'\$([0-9.,]+)', amount)
    if match:
        return f"{match.group(1)} USD"
    match = re.match(r'€([0-9.,]+)', amount)
    if match:
        return f"{match.group(1)} EUR"
    return amount

def convert_line(line):
    """Convert a single line."""
    # Skip comments
    if line.strip().startswith(';') or line.strip().startswith('#'):
        return line

    # Convert posting
    match = re.match(r'(\s+)([a-z:]+)\s+(.+)', line)
    if match:
        indent, account, amount = match.groups()
        return f"{indent}{title_case(account)}  {convert_amount(amount.strip())}\n"

    # Convert transaction header
    match = re.match(r'(\d{4}-\d{2}-\d{2})\s+(.+)', line)
    if match:
        date, payee = match.groups()
        return f'{date} * "{payee.strip()}"\n'

    return line

if __name__ == '__main__':
    for line in sys.stdin:
        print(convert_line(line), end='')

Usage:

python3 convert.py < main.journal > ledger.beancount

Note: This is a starting point. Manual review and cleanup will be needed.

Troubleshooting

Account Name Errors

Ensure accounts are Title:Case:

Error: Invalid account name 'expenses:food'
Fix: Use 'Expenses:Food'

Missing Open Directives

Generate them:

rledger doctor missing-open ledger.beancount

Balance Assertion Failures

Check date format and amount:

; hledger: balance assets:checking  = $1234.56
; beancount:
2024-01-15 balance Assets:Checking  1234.56 USD
