I wondered whether we could make this executable as it is, but for that
we’d have to create one procedure for every date.
Since accounts have to be declared with something like
account ArneBab:Assets:Autorenhonorar:epubli
creating a proc per account would actually give us some compile-time
validation.
import : ice-9 optargs
define USD 'USD
define-syntax-rule (account name)
define* (name #:optional value currency)
list (quote name) value currency
define (entry description
account-name1 value1 currency1
account-name2 value2 currency2)
;; do something useful
. description
define-syntax date
λ : x
syntax-case x : *
: _ * description account1 account2
#' apply entry : cons description : append account1 account2
define-syntax-rule : 2020-03-30 args ...
date args ...
;; Missing piece: Running
;; define-syntax-rule (the-date args ...) (date args ...)
;; for each possible date.
And actually implementing some state tracking …
This already works (but only returns "Starting balance"):
account Assets:Retirement:IRA
account Equity:OpeningBalance
2020-03-30 * "Starting balance"
Assets:Retirement:IRA 1321.84 USD
Equity:OpeningBalance
Best wishes,
Arne
