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.
Prior to this commit,
- hledger still builds with GHC 8.0
- hledger-ui does if you use the build plan specified by stack8.0.yaml,
but you are likely to hit problems if you let cabal pick one
(https://github.com/jtdaugherty/vty/issues/198 and others)
- hledger-web might, if you could find the right build plan
The hassles are enough and GHC 8.0 is old enough (first released in
2016) that I'm letting it go; 8.2 is the new minimum version for all
hledger packages.
This allows a bunch of cleanups to conditional imports, which I leave
for later.
Also, updated the tested-with minor versions.
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.
On the accounts screen and register screen we round amounts according
to commodity styles, but when you drill down to a transaction you
probably want to see the unrounded amounts.
independently.
You can now combine costing and valuation, for example "--cost
--value=then" will first convert to costs, and then value according to
the "--value=then" strategy. Any valuation strategy can be used with or
without costing.
If multiple valuation and costing strategies are specified on the
command line, then if any of them include costing
(-B/--cost/--value=cost) then amounts will be converted to cost, and for
valuation strategy the rightmost will be used.
--value=cost is deprecated, but still supported and is equivalent to
--cost/-B. --value=cost,COMM is no longer supported, but this behaviour can be
achieved with "--cost --value=then,COMM".
costing and valuation.
This currently is given a dummy NoCost argument and is equivalent to
"maybe id (*ApplyValuation ...)", but provides a constant interface so
that internal behaviour can be changed freely.
