We need this for choosing a valuation date, otherwise, report
functions would have to be in IO or we'd have to pass in yet another
argument.
It's optional because it's useful to be able to create report opts
purely (I think ?) This is not ideal but maybe not a problem.
Instead of converting all journal amounts to value early on, we now
convert just the report amounts to value, before rendering.
This was basically how it originally worked (for the balance command),
but now it's built in to the four basic reports used by print,
register, balance and their variants - Entries, Postings, Balance,
MultiBalance - each of which now has its own xxValue helper.
This should mostly fix -V's performance when there are many
transactions and prices (the price lookups could still be optimised),
and allow more flexibility for report-specific value calculations.

There's one new limitation, not yet resolved: -V once again can pick a
valuation date in the future, if no report end date is specified and
the journal has future-dated transactions. We prefer to avoid that,
but reports currently are pure and don't have access to today's date.
-V is still quite a bit slower than no -V, but not as much as before:

I needed to be more careful about ordering, as johannesgerer's original
code was, and the tests missed it. I think I have it now.
Found the PR whose code I have been reworking, it was #438.
Hopefully this is will do it. This restores the past behaviour:
- parsing prices in balance assertions/assignments
- ignoring them in assertions
- using them in assignments
- and printing them
and clarifies tests and docs.
Going with option 1b from the issue: calculated and asserted amounts
are compared exactly, disregarding display precision.
But now balance assertion failure messages show those exact amounts at
full precision, avoiding confusion.
Surprisingly, balance assertions were checking to maximum precision,
which meant it was possible, with a display-precision-limiting
commodity directive, to have a failing assertion with the error
message showing asserted and actual amounts that looked the same.
Now we round the calculated account balance (but not the asserted
balance) to display precision before comparing. This should ensure
assertions always behave as you would expect from visual inspection.
This should eventually include accountnames from transaction
modifiers (if `--auto` is enabled), or periodic transactions (if
`--forecast` is enabled).
- parse a period expression by first extracting words separated by
single spaces, then by "re-parsing" this text with 'periodexprp'
- this way, the period expression parsers do not need to know about
the single- or double-space rules
A different approach: instead of converting to unit prices and fiddling
with the display precision, just multiply the total prices by the same
multiplier (and keep them positive).
This seems a little more natural. I'm not sure if one of these will be
more robust than the other.
Divide/multiply amounts *and* their total price, if they have one.
Helpful for keeping transactions balanced when transaction modifiers are
multiplying amounts.
Transaction modifier multipliers have never multiplied total-priced amounts
correctly (and prior to hledger 1.10, this could generate unbalanced
transactions).
Now, the generated postings in this situation will have unit prices,
and an extra digit of display precision. This helps ensure that
the modified transaction will remain balanced. I'm not sure yet if
it's guaranteed.
Noticed by peti: showTransaction could sometimes hide the last posting's
amount even if one of the other posting amounts was already implcit,
producing invalid transaction output.
* journal: Get rid of `journalFinalise` and use granular functions
Complete the process started in 53b3e2bd. This gets rid of the
`journalFinalise` function and uses the smaller steps, in order to
have more granular control.
* journal: Change order of operations in finalization
We want to make sure that we add the filepath after the order is
reversed, so the added filepath is on the head and not the tail (as it
would be if it were reversed after it was added).
* journal: Refine granular finalization functions
This commit fixes two of the granular finalization functions:
1. Rename `journalSetTime` to `journalSetLastReadTime` and improve
documentation.
2. Remove `journalSetFilePath`. It's redundant with `journalAddFile`
currently in `Hledger.Read.Common`. The only difference between the
functions is where the file is added (we keep the one in which it
is added to the tail), so we change the position vis-a-vis
reversal.
`journalFinalise` is only used in the `parseAndFinaliseJournal`
functions, but it needs to be run differently at different stages when
transaction modifiers are applied. This change breaks it into smaller
functions, and uses those smaller parts in `parseAndFinaliseJournal`
as needed.
Previously we ran if `--auto` was set. But this adds a small
performance hit if `--auto` becomes default. Now we only run twice if
there are transactionModifiers AND `--auto` is set. So even if auto is
specified, there will be no penalty if there are no modifiers.
Currently, automated transactions are added before the journal is
finalized. This means that no inferred values will be picked up. We
change the procedure, if `auto_` is set, to
1. first run `journalFinalise` without assertion checking (assertions
might be wrong until automated transactions), but with reordering
2. Insert transaction modifiers
3. Run `journalFinalise` again, this time with assertion checking as
set in the options, and without reordering.
If `auto_` is not set, all works as before.
Closes: #893
Currently `journalFinalise` always reverses the order of
entries. However, if there are automated transactions, we might need
to run it twice. This adds a boolean flag to make reordering
optional. This will be used in the `parseAndFinaliseJournal`
functions.
