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).
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.
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.
These commands now detect the account types declared by account directives.
Whenever such declarations are not present, built-in regular expressions
are used, as before.
Previously you had to use one of the standard english account names
(assets, liabilities..) for top-level accounts, if you wanted to use
the bs/bse/cf/is commands.
Now, account directives can specify which of the big five categories
an account belongs to - asset, liability, equity, revenue or expense -
by writing one of the letters A, L, E, R or X two or more spaces after
the account name (where the numeric account code used to be).
This might change. Some thoughts influencing the current syntax:
- easy to type and read
- does not require multiple lines
- does not depend on any particular account numbering scheme
- allows more types later if needed
- still anglocentric, but only a little
- could be treated as syntactic sugar for account tags later
- seems to be compatible with (ignored by) current Ledger
The current design permits unlimited account type declarations anywhere
in the account tree. So you could declare a liability account somewhere
under assets, and maybe a revenue account under that, and another asset
account even further down. In such cases you start to see oddities like
accounts appearing in multiple places in a tree-mode report. In theory
the reports will still behave reasonably, but this has not been tested
too hard. In any case this is clearly too much freedom. I have left it
this way, for now, in case it helps with:
- modelling contra accounts ?
- multiple files. I suspect the extra expressiveness may come in handy
when combining multiple files with account type declarations,
rewriting account names, apply parent accounts etc.
If we only allowed type declarations on top-level accounts, or
only allowed a single account of each type, complications seem likely.
- In anticipation of megaparsec 7, which removes support for stacks of
include files (as far as I can tell)
- Intended for the 'StateT Journal' layer of the parser
- A stack of include files would be better in a 'ReaderT' layer, but I
don't want to add another layer to the parser
- Intended for detecting cycles of include files
- Potential issue: for proper error messages for include file cycles,
we must remember to provide the filepath of the root journal file via
the initial journal state passed to a 'JournalParser'; I imagine
that we may forget to do so because in all other cases it is okay
not to do so.
