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.
price directives after the last transaction/posting date if using
--value=end.
Also enlarges the reportspan to encompass full intervals for budget
goals.
add --debug=1 shows the top hits for similar past transactions.
added:
Hledger.Cli.Utils.journalSimilarTransaction
provides --debug=1 output
changed:
Hledger.Cli.Commands.Add.transactionsSimilarTo -> Hledger.Data.Journal.journalTransactionsSimilarTo
now takes an extra number-of-results argument
Ensures parseable and more sensible-looking output in more cases, and behaves more like Ledger's print.
There is still an issue with adding trailing zeroes, which would be nice to prevent.
Command-line account aliases now also affect transactions read
from these formats (not just journal format).
lib: journalApplyAliases, transactionApplyAliases, postingApplyAliases
helpers have been added.
Journal keeps a new piece of parsing state, a decimal mark character,
which can optionally be set to force the number format expected by all
amount parsers.
D directives are now fully equivalent to commodity directives for
setting a commodity's display style. (Previously it was equivalent to
a posting amount, so it couldn't limit the number of decimal places.)
When both kinds of directive exist, commodity directives take precedence.
When there are multiple D directives in the journal, only the last one
affects display style.
Stop exporting journalAmounts, overJournalAmounts, traverseJournalAmounts.
Rename journalAmounts helper to journalStyleInfluencingAmounts.
D directives are now a little better at influencing amount
canonicalisation, eg in the updated test case.
