mixedAmount(Looks|Is)Zero now operate directly on the MixedAmount,
rather than converting them to a list of amounts first.
mixedAmountCost no longer reconstructs the entire MixedAmount when there
are amounts with no cost.
transactionCheckBalanced only checks if signs are okay if sums are not
okay. It also only traverses the list of postings once when picking real
and balanced virtual postings.
There are no modules which depend on Hledger.Data.Commodity which don't
also depend on Hledger.Data.Amount. Though Hledger.Data.Amount is a very
large module and might be broken up, Hledger.Data.Commodity only defines
three very small functions which are used, and so can be combined with
little cost.
We can't filter out empty commodity strings since that is a legitimate
group. Simultaneously, we should only include the empty commodity if it
is explicitly used (part of a posting) and not generated as part of
`Amounts.amounts`
This adds the `--commodity-column` option that displays each commodity
on a separate line and the commodities themselves as a separate column.
The initial design considerations are at
simonmichael.hledger.issues.1559
The single-period balance report with `--commodity-column` does not
interoperate with custom formats.
In Amount, aismultiplier is a boolean flag that will always be False,
except for in TMPostingRules, where it indicates whether the posting
rule is a multiplier. It is therefore unnecessary in the vast majority
of cases. This posting pulls this flag out of Amount and puts it into
TMPostingRule, so it is only kept around when necessary.
This changes the parsing of journals somewhat. Previously you could
include an * before an amount anywhere in a Journal, and it would
happily parse and set the aismultiplier flag true. This will now fail
with a parse error: * is now only acceptable before an amount within an
auto posting rule.
Any usage of the library in which the aismultiplier field is read or set
should be removed. If you truly need its functionality, you should
switch to using TMPostingRule.
This changes the JSON output of Amount, as it will no longer include
aismultiplier.
This change provides more predictable and intuitive behaviour when
using -S/--sort-amount with multiple commodities.
It implements a custom Ord (and Eq) instance for MixedAmount
which substitutes zero for any missing commodities.
As a consequence, all the ways of representing zero with a MixedAmount ([],
[A 0], [A 0, B 0, ...]) are now Eq-ual (==), whereas before they were
not. We have not been able to find anything broken by this change.

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.

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.
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.
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.
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
This introduces some new helper functions which are exactly the same
as what we had before, but do not call
normaliseMixedAmountSquashPricesForDisplay, so that we can use the new
functions for displaying Transaction and Posting. It also goes through
and gets rid of most uses of the old showMixed* functions which would
benefit from using the new interface.
This changes showMixedAmountElided so that the width to elide to is
given as an argument, rather than fixed at 22 characters. This
actually uses the new renderTable interface. Mostly this is just an
internal change, but since we have more information about the widths
of things, we can actually get rid of some superfluous spaces in the
budget report output, previously there to make sure it stayed aligned
with the largest reasonable contents.
Previously showMixedAmountElided would show two amounts and then the
elision string if necessary. Now it will display as many Amounts as it
can subject to the condition that the amounts plus the elision string
fit within 22 characters.
