A commodity directive that doesn't specify the decimal point character
increases ambiguity and the chance of misparsing numbers, especially
as it overrides all style information inferred from the journal amounts.
In some cases it caused amounts with a decimal point to be parsed as if
with a digit group separator so 1.234 became 1234.
We could augment it with extra info from the journal amounts, when available,
but it would still be possible to be ambiguous, and that won't be obvious.
A commodity directive is what we recommend to nail down the style.
It seems the simple and really only way to do this reliably is to require
an explicit decimal point character. Most folks probably do this already.
Unfortunately, it makes another potential incompatiblity with ledger and
beancount journals. But the error message will be clear and easy to
work around.
Inferred amounts now have the appropriate standard amount style applied.
And when checking for balanced transactions, amount styles declared with
commodity directives are also used (previously only inferred amount styles were).
Now we have:
-- | Sorted unique account names posted to by this journal's transactions.
journalAccountNamesUsed :: Journal -> [AccountName]
-- | Sorted unique account names implied by this journal's transactions -
-- accounts posted to and all their implied parent accounts.
journalAccountNamesImplied :: Journal -> [AccountName]
-- | Sorted unique account names declared by account directives in this journal.
journalAccountNamesDeclared :: Journal -> [AccountName]
-- | Sorted unique account names declared by account directives or posted to
-- by transactions in this journal.
journalAccountNamesDeclaredOrUsed :: Journal -> [AccountName]
-- | Sorted unique account names declared by account directives, or posted to
-- or implied as parents by transactions in this journal.
journalAccountNamesDeclaredOrImplied :: Journal -> [AccountName]
-- | Convenience/compatibility alias for journalAccountNamesImpliedOrUsed.
journalAccountNames :: Journal -> [AccountName]
accountsFromPostings is currently doing excessive work when adding up
postings in each account. It sorts (accountName, amount) tuples which
cause amounts in them to be compared. There is no need to look at amount
here at all since subsequent summing up and counting does not depend on
order. It is enough to sort by accountname only.
Went through similar pieces of code, made them all look uniform.
- Simplify doctests for periodexpr.
- Besides consuming leading space consume ending space for periodexpr also.
- Drop implicit option (def, def) behaviour of periodexpr. I.e. disallow
hledger reg -p '' and auto-transaction with heading just '~'.
- Slightly re-factor periodexpr.
- Ensure that reportinginterval doesn't consume trailing space.
Useful if we'll start disallowing periods like "every1stjan2009-".
This is very helpful for periodic transactions, because in budget mode
you need to ensure that no periodic transactions extend past the end
of the journal, and in forecast mode you need to make sure that all
periodic transactions are strictly after the end of the journal.
Some of these demonstrate that runPeriodicTransaction could generate
transactions ouside of requested DateSpan. This happens because
runPeriodicTransaction uses splitSpan internally, and splitSpan always
generates dateSpans that fully cover original DateSpan, extending
beyound left/right boundary if necessary. This is ok if transactions
are generated for budgeting purpose, but during forecasting care should
be taken to check that all generated transactions are happening past
the end of the real journal.
Currently only lower-case account names are supported, both on the
command line, and in the journal (in periodic transactions):
This works:
$ hledger balance -p nov
This does not:
$ hledger balance -p Nov
First transaction will parse, second will not:
```
cat every-month.journal ~/devel/haskell/darcs-get/hledger/examples
~ aug to sep
assets
expenses $1
~ Aug to Sep
assets
expenses $2
```
$../bin/hledger-budget bal -f every-month.journal
hledger-budget: Failed to parse "Aug to Sep": date parse error ()
This commit fixes both cases.
