Migrating from Ledger-CLI

This guide helps you migrate from ledger-cli to rustledger's beancount format.

Key Differences

Syntax

Feature	Ledger	Beancount
Account separator	:	:
Transaction flag	None or */!	Required * or !
Amounts	Right side	Right side
Balance assertions	= AMOUNT	balance directive
Currencies	After amount	After amount
Comments	; or #	;

Philosophy

Aspect	Ledger	Beancount
Double-entry	Optional	Required
Balance checking	Optional	Always
Account declaration	Optional	Required (open)
Commodity declaration	Optional	Optional (commodity)

Conversion Example

Ledger Format

; ~/.ledger
2024-01-15 Coffee Shop
    Expenses:Food:Coffee     $5.00
    Assets:Cash

2024-01-16 * Grocery Store
    Expenses:Food:Groceries  $45.00
    Assets:Checking

= Expenses:Food
    [Budget:Food]           -1.0

Beancount Format

; ledger.beancount
option "operating_currency" "USD"

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

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

2024-01-16 * "Grocery Store"
  Expenses:Food:Groceries  45.00 USD
  Assets:Checking         -45.00 USD

Migration Steps

1. Export from Ledger

First, print your ledger in a clean format:

ledger -f ledger.dat print > ledger-export.dat

2. Convert Syntax

Key changes needed:

Add Account Opens

Extract all accounts and create opens:

ledger -f ledger.dat accounts | while read account; do
  echo "2020-01-01 open $account"
done > accounts.beancount

Convert Transactions

For each transaction:

1. Add quotes around payee: "Payee Name"
2. Add flag if missing: * for cleared
3. Ensure amounts balance explicitly (no auto-balance)
4. Change $5.00 to 5.00 USD

Convert Balance Assertions

Ledger:

2024-01-31 Balance
    Assets:Checking  = $1234.56

Beancount:

2024-01-31 balance Assets:Checking  1234.56 USD

3. Conversion Script

Basic conversion script (adjust as needed):

#!/bin/bash
# convert-ledger.sh

INPUT="$1"
OUTPUT="${INPUT%.dat}.beancount"

# Extract and create account opens
echo "; Accounts" > "$OUTPUT"
ledger -f "$INPUT" accounts | while read account; do
  echo "2020-01-01 open $account" >> "$OUTPUT"
done

echo "" >> "$OUTPUT"
echo "; Transactions" >> "$OUTPUT"

# This is a starting point - manual review needed
ledger -f "$INPUT" print >> "$OUTPUT"

echo "Exported to $OUTPUT - manual conversion needed"

4. Manual Cleanup

After automated conversion, manually:

1. Add quotes around payees
2. Fix commodity positions ($5.00 → 5.00 USD)
3. Add explicit balancing amounts
4. Review balance assertions

5. Validate

rledger check ledger.beancount

Fix errors until validation passes.

Command Mapping

Ledger Command	rustledger Command
ledger bal	rledger report balances
ledger reg	rledger report journal
ledger print	rledger format
ledger accounts	rledger report accounts
ledger payees	rledger query "SELECT DISTINCT payee"
ledger commodities	rledger report commodities

Shell Aliases

Recreate familiar commands:

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

alias bal='rledger report "$LEDGER_FILE" balances'
alias reg='rledger report "$LEDGER_FILE" journal'

# With account filter
bal() {
  rledger report "$LEDGER_FILE" balances ${1:+-a "$1"}
}

reg() {
  rledger report "$LEDGER_FILE" journal ${1:+-a "$1"}
}

See Shell Aliases Guide for more.

Feature Comparison

Available in Both

• Double-entry accounting
• Multiple commodities/currencies
• Command-line interface
• Reports (balance, register)
• Date filtering

Ledger Features Not in Beancount

• Automated transactions: Use plugins instead
• Periodic transactions: Not supported
• Virtual accounts: Use tags instead
• Flexible balance: Must always balance

Beancount Features Not in Ledger

• Booking methods: FIFO, LIFO, etc.
• BQL query language: SQL-like queries
• Plugins: Extensible validation
• LSP support: Editor integration

Troubleshooting

"Transaction does not balance"

Beancount requires explicit balancing. Add the missing leg:

2024-01-15 * "Coffee"
  Expenses:Food    5.00 USD
  Assets:Cash     -5.00 USD  ; Must be explicit

"Account not opened"

Add open directive before first use:

2020-01-01 open Expenses:Food

Or use rledger doctor missing-open to generate them.

Commodity Position

Move commodity after amount:

Wrong: $5.00
Right: 5.00 USD
