Hi everyone,
sorry if this is a dumb question but I've been unable to find an answer.
I wrote a small price fetcher for the milan stock exchange, which works by scraping the website
and works well enough.
But, to find a price I need to use the ISIN rather than the ticket price,
which means I have to specify the price like
EUR:borsa_italiana/IE00BDBRDM35:AGGH
this in turn results in the generation of a price tag that looks like
2019-08-16 price IE00BDBRDM35:AGGH 5.271 EUR
but I'd rather not have the ISIN in my commodity name.
AFAICT, the find_prices machinery does not have any ability to specify
separate symbol names for output and lookups, a PriceSource cannot set it or
return it.
I don't see this done for the quandl source either, resulting in WiKI:FOO names.
I guess I could hack something with dynamic module loaders but it seems to me
this should be possible, and useful in general, maybe having a "?name=FOO"
extra bit in the price (which feels URI-ish anyway)
If there's a non-hackish way to do this?
Thanks in advance for any help, and thanks for beancount, it's very cool!
PS
Maybe this already works for prices defined as metadata for commodities?
I could not check as I could never get bean-price to run on my ledger file, due to the same error

Yes, it works for prices defined as metadata for commodities.

The thing you are linking to says it has been resolved a long time ago: https://bitbucket.org/blais/beancount/issues/395/using-bean-price-all-causes-an-error

yes but it still happens for me, having install beancount for the first time last week.
2.2.1 is, as far as I can tell, the latest released tag.
$ bean-price -V
Beancount 2.2.1
Beancount 2.2.1

In this case it appears that "fixed a long time ago" doesn't mean it has actually made its way into a release.
2.2.1 was tagged in January, I think, and you're right it seems to show that same error. I confirmed that it works fine with tip from bitbucket.
