We don't do a good job of calculating good-looking unit prices when the
commodity display precisions are low. Eg when a journal doesn't use any
decimal places, any inferred unit prices are shown by the print command
also with no decimal places, which makes them look wrong.
Now inferred unit prices always have a minimum display precision of 2,
which helps a bit. Could do better.
When a transaction posts to two commodities without specifying the
conversion price, we generate a price which makes it balance
(cf http://hledger.org/manual.html#prices).
Until now, these generated prices were always shown with full precision
(all available decimal digits) so that a manual calculation with the
displayed numbers would agree.
If there's just one posting in the commodity being priced, we can use an
exact total price and the precision is no problem.
But if there are multiple postings in the commodity being priced, we
must show the averaged unit price. This can be an irrational number,
which with our current Decimal-based implementation would display an
excessive 255 decimal digits. So in this case we now set the price's
display precision to the sum of the (max) display precisions of the
commodities involved. An example:
hledgerdev -f- print
<<<
1/1
c C 10.00
c C 11.00
d D -320.00
>>>
2015/01/01
c C 10.00 @ D 15.2381
c C 11.00 @ D 15.2381
d D -320.00
>>>=0
There might still be cases where this will show more price decimal
places than necessary. For now, YAGNI.
A transaction/posting status of ! (pending) was effectively equivalent
to * (cleared). Now it's a separate state, not matched by --cleared.
The new Ledger-compatible --pending flag matches it, and so does
--uncleared. The equivalent search queries are now status:*, status:!
and status: (the old status:1 and status:0 spellings are deprecated).
Since we interpret --uncleared and status: as "any state except cleared",
it's not currently possible to match things which are neither cleared
nor pending.
- use new query system for command line too, filterspec is no more
- move unit tests near the code they test, run them in bottom up order, add more
- more precise Show instances, used for debugging not ui
Ledger shows only the effective date with --effective, but not vice versa.
print is supposed to be information-preserving so this seems better.
This also fixes the web entries view.
Like ledger, price amounts are now "unobserved", ie their precision does
not affect the canonical display precisions used when displaying amounts,
and transaction balancing is done based on display precision, ie amounts
are considered to balance if their sum appears to be zero when using the
canonical display precision.
