This does costing and valuation on a journal, and is meant to replace
most direct calls of costing and valuation. The exception is for reports
which require amounts to be summed before valuation is applied, for
example a historical balance report with --value=end.
instead of a list of Amounts. No longer export Mixed constructor, to
keep API clean (if you really need it, you can import it directly from
Hledger.Data.Types). We also ensure the JSON representation of
MixedAmount doesn't change: it is stored as a normalised list of
Amounts.
This commit improves performance. Here are some indicative results.

If you never directly use the constructor Mixed or pattern match against
it then you don't need to make any changes. If you do, then do the
following:
- If you really care about the individual Amounts and never normalise
your MixedAmount (for example, just storing `Mixed amts` and then
extracting `amts` as a pattern match, then use should switch to using
[Amount]. This should just involve removing the `Mixed` constructor.
- If you ever call `mixed`, `normaliseMixedAmount`, or do any sort of
amount arithmetic (+), (-), then you should replace the constructor
`Mixed` with the function `mixed`. To extract the list of Amounts, use
the function `amounts`.
- If you ever call `normaliseMixedAmountSquashPricesForDisplay`, you can
replace that with `mixedAmountStripPrices`. (N.B. this does something
slightly different from `normaliseMixedAmountSquashPricesForDisplay`,
but I don't think there's any use case for squashing prices and then
keeping the first of the squashed prices around. If you disagree let
me know.)
- Any remaining calls to `normaliseMixedAmount` can be removed, as that
is now the identity function.
ANSI color on stdout (not stderr) is now disabled if the

Added outputFileOption, and more advice in comments.
we know we won't need them.
Knowing whether we need them is accomplished by pulling the "show-costs"
option used by the Close command up into ReportOpts.
existing representation is small enough.
Previously the JSON representation of Decimal was rounded to 10 points
of precision before serialising. This sometimes results in an
unnecessary increase of precision.
It now uses the same JSON representation as Maybe Word8. This means that
the JSON serialisation is now broadly compatible with that used before the
commit f6fa76bba7, differing only in
how it handles numbers outside Word8 and that it can now produce null
for NaturalPrecision.
Comparing two Quantity (either with (==) or compare) does a lot of
normalisation (calling roundMax) which is unnecessary if we're comparing
to zero. Do things more directly to save work.
For reg -f examples/10000x10000x10.journal, this results in
- A 12% reduction in heap allocations, from 70GB to 62GB
- A 14% reduction in (profiled) time, from 79s to 70s
Results for bal -f examples/10000x10000x10.journal are of the same order
of magnitude.
rather than lists. This is probably not an enormous performance sink in real
situations, but it takes a huge amount of time and memory in our
benchmarks (specifically 10000x10000x10.journal).
For bal -f examples/10000x10000x10.journal, this results in
- A 23% reduction in heap allocation, from 27GiB to 21GiB
- A 33% reduction in (profiled) time running, from 26.5s to 17.9s

For reg -f examples/10000x10000x10.journal, this results in:
- Heap allocations decreasing by 55%, from 68.6GB to 31.2GB

- Total (profiled) time decreasing by 55%, from 37s to 20s
former being a simple wrapper around the latter.
This removes the need for the showNormalised option, as showMixedAmountB
will always showNormalised and showAmountsB will never do so.
We also strip prices from MixedAmount before displaying if not displaying prices.
Exceptions are for dealing with the pamount field, which is really just
dealing with an unnormalised list of amounts.
This creates an API for dealing with MixedAmount, so we never have to
access the internals outside of Hledger.Data.Amount.
Also remove a comment, since it looks like #1207 has been resolved.
supplant the old interface, which relied on the Num typeclass.
MixedAmount did not have a very good Num instance. The only functions
which were defined were fromInteger, (+), and negate. Furthermore, it
was not law-abiding, as 0 + a /= a in general. Replacements for used
functions are:
0 -> nullmixedamt / mempty
(+) -> maPlus / (<>)
(-) -> maMinus
negate -> maNegate
sum -> maSum
sumStrict -> maSum
Also creates some new constructors for MixedAmount:
mixedAmount :: Amount -> MixedAmount
maAddAmount :: MixedAmount -> Amount -> MixedAmount
maAddAmounts :: MixedAmount -> [Amount] -> MixedAmount
Add Semigroup and Monoid instances for MixedAmount.
Ideally we would remove the Num instance entirely.
The only change needed have nullmixedamt/mempty substitute for
0 without problems was to not squash prices in
mixedAmount(Looks|Is)Zero. This is correct behaviour in any case.

Also enlarges the reportspan to encompass full intervals for budget

both the quantity and the cost are zero. This is usually what you want,
but if you do only want to check whether the quantity is zero, you
can run mixedAmountStripPrices (or similar) before this.
(multiply|divide)(Mixed)?Amount now also multiply or divide the
TotalPrice if it is present, and the old
(multiply|divide)(Mixed)?AmountAndPrice functions are removed.
internally, closing a big space leak.
This also now combines Amounts with TotalPrices in the same commodity
when normalising; amounts with TotalPrices were previously never
combined.
aquantity.
Journal entries still require a positive @@ price, but now the sign is
set after parsing, rather than when converting in amountToCost.
The reason for this change is that, if we're going to perform arithmetic
on Amount with TotalCost, then the presence of aquantity=0 means that
amountToCost would render the total cost as 0, because signum 0 == 0.
This makes journal entries like the following impossible to balance:
2000-01-01
a 0 @@ 10 A
b -10 A
