(SourcePos, SourcePos).
This has been marked for possible removal for a while. We are keeping
strictly more information. Possible edge cases arise with Timeclock and
CsvReader, but I think these are covered.
The particular motivation for getting rid of this is that
GenericSourcePos is creating some awkward import considerations for
little gain. Removing this enables some flattening of the module
dependency tree.
POSIXTime.
This eliminates old-time, which has been deprecated for a while, from
our dependencies.
This introduces a slight incompatibility, as a small number of functions
now take/return POSIXTime instead of ClockTime. Generally you will be
using the current time, in which case you should use getPOSIXTime from
Data.Time.Clock.POSIX instead of getClockTime.
utcTimeToClockTime has been removed, as it is now equivalent to
utcTimeToPOSIXSeconds from Data.Time.Clock.POSIX.
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.
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.
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.
Amounts in JSON are now rendered as simple Numbers with up to 10
decimal places, instead of Decimal objects which would in some cases
have 255 digits, too many for most JSON parsers to handle.
A provisional fix, see the comment in Json.hs for more detail.
