NAME

       gnc-fq-helper  -  allows gnucash to communicate with Finance::Quote
                         over pipes from guile. The requests and responses
                         are scheme forms.

SYNOPSIS

       gnc-fq-helper

DESCRIPTION

       Input: (on standard input - one entry per line and one line per entry, and double quotes
       must only be delimiters, not string content -- remember, we don't have a real scheme
       parser on the perl side :>).

       (<method-name> symbol symbol symbol ...)

       where <method-name> indicates the desired Finance::Quote method.  The currently recognized
       subset is yahoo, yahoo_europe, fidelity_direct, troweprice_direct, vanguard, asx,
       tiaacref, and currency.

       For currency quotes, the symbols alternate between the 'from' and 'to' currencies.

       For example:

       (yahoo "IBM" "LNUX") (fidelity_direct "FBIOX" "FSELX") (currency "USD" "AUD")

       Output (on standard output, one output form per input line):

       Schemified version of gnc-fq's output, basically an alist of alists, as in the example
       below.  Right now, only the fields that this script knows about (and knows how to convert
       to scheme) are returned, so the conversion function will have to be updated whenever
       Finance::Quote changes.  Currently you'll get symbol, gnc:time-no-zone, and currency, and
       either last, nav, or price.  Fields with gnc: prefixes are non-Finance::Quote fields.
       gnc:time-no-zone is returned as a string of the form "YYYY-MM-DD HH:MM:SS", basically the
       unmolested (and underspecified) output of the quote source.  It's up to you to know what
       it's proper timezone really is.  i.e. if you know the time was in America/Chicago, you'll
       need to convert it to that.

       For example:

        $ echo '(yahoo "CSCO" "JDSU" "^IXIC")' | ./gnc-fq-helper
       (("CSCO" (symbol . "CSCO")
                (gnc:time-no-zone . "2001-03-13 19:27:00")
                (last . 20.375)
                (currency . "USD"))
        ("JDSU" (symbol . "JDSU")
                (gnc:time-no-zone . "2001-03-13 19:27:00")
                (last . 23.5625)
                (currency . "USD"))
       ("^IXIC" (symbol . ^IXIC)
                (gnc:time-no-zone . 2002-12-04 17:16:00)
                (last . 1430.35)
                (currency . failed-conversion)))

       On error, the overall result may be #f, or on individual errors, the list sub-item for a
       given symbol may be #f, like this:

        $ echo '(yahoo "CSCO" "JDSU")' | ./gnc-fq-helper
       (#f
        ("JDSU" (symbol . "JDSU")
                (gnc:time-no-zone . "2001-03-13 19:27:00")
                (last . 23.5625)
                (currency . "USD")))

       further, errors may be stored with each quote as indicated in Finance::Quote, and whenever
       the conversion to scheme data fails, the field will have the value 'failed-conversion, and
       accordingly this symbol will never be a legitimate conversion.

       Exit status

       0 - success non-zero - failure
