GNC-FQ-HELPER(1) User Contributed Perl Documentation GNC-FQ-HELPER(1)NAMEgnc-fq-helper - allows gnucash to communicate with Finance::Quote
over pipes from guile. The requests and responses
are scheme forms.
SYNOPSISgnc-fq-helperDESCRIPTION
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
