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-".
Cleaned-up versions of a number of related PRs relating to budgeting,
periodic transactions, automated postings and period expressions, such
as: #644, #645, #646, #647, #651, #652, #653.
Budget goals specified with periodic transactions (as with
hledger-budget) can now be displayed in balance report (but not in bs/is/cf).
--budget shows the target amount and percentage alongside the actual
amount, per account and period.
Unbudgeted accounts will be hidden, unless --show-unbudgeted is used.
Budgeted accounts are displayed folded (depth-clipped) at a depth
matching the budget specification. Unbudgeted accounts, if shown, are
displayed at their usual depth (in full detail, or according to --depth).
Ledger-style automated postings, previously supported only by
hledger-budget, have landed as a first-class feature. The --auto
flag activates them, so that any postings they generate are
included in reports.
Ledger-style periodic transactions, previously supported only by
hledger-budget, have landed as a first-class feature. The --forecast
flag activates them, so that any transactions they generate are
included in reports.
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.
Might need to be more specific or rename the developer/contributor guide
later. For users, for now, it's Introduction, Guide and Reference.
Still TBD where the basic getting started tutorial lives.
