# ledgereval [EXPR] - evaluate a Ledger value expression
# This runs `ledger eval`, but also accepts standard input, and does not add a newline.
# It's useful eg when converting Ledger's amount expressions to simple amounts.
# Decimal places can be important, eg ledgereval '0.01 USD / 2' vs ledgereval '0.010 USD / 2'.

expr="${*:-$(cat)}"
printf '%s' "$(ledger eval "$expr")"
