eb23504906 lib: periodexprp: don't consume trailing whitespace 2018-06-12 16:41:36 -07:00
Alex Chen
c6bfd92dd3 removing "re-parsing" for pull 807 
For Data/Dates.hs in particular:
- Changed `SimpleTextParser` to `TextParser m` for all parsers
- Changed `string` to the case-insensitive `string'` to match the
  behaviour of `T.toLower` found in `parsePeriodExpr`
- export `periodexprp` for "direct" use

c5561f25f1 lib: switch parsers to the custom error type 
Also add an explicit export list to `hledger-lib/Hledger/Utils/Parse.hs`
in order to re-export the custom error type (for convenience).

0ce9c5728a switch to base-compat-batteries to fix ghc 7.10 support (#794) 
base-compat-batteries provides the same API across more ghc versions
than base-compat does, at the cost of more dependencies. Eg it exports
Prelude.Compat ((<>)) with ghc 7.10/base 4.8, which we expect.
My belief is that several of our deps already require it so the added
cost is not too great. We should probably go back to base-compat when
possible though, eg when we stop supporting ghc 7.10.

6db7f800ee hledger-lib: fix doctest suite after recent package updates 
The new version of our package set apparently contains both base-compat and
base-compat-batteries in its transitive closure. This breaks the doctest suite,
which just imports everything into scope when the tests are run, thereby making
module names like Prelude.Compat ambiguous.

48623b4ceb lib: fix backtracking in periodexpr parser 
- 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-".

597e9c47c9 lib: more periodic transaction tests 
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.

7acb5d45aa lib: make month names in period expressions case-insensitive 
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.

4049455f26 lib: Fix splitSpan for nthdayof{week,month} - start of DateSpan was not covered 
Demonstration:

Consider year-test.journal:
```
2015/02/01 first half
    expenses  $1
    assets

2015/07/01 second half
    expenses  $2
    assets

2016/02/01 first half
    expenses  $4
    assets

2016/07/01 second half
    expenses  $8
    assets

2017/02/01 first half
    expenses  $16
    assets

2017/07/01 second half
    expenses  $32
    assets
```

Year balances are good:
```
$ hledger balance -f year-test.journal -p yearly
Balance changes in 2015/01/01-2017/12/31:

          || 2015  2016  2017
==========++==================
 assets   ||  $-3  $-12  $-48
 expenses ||   $3   $12   $48
----------++------------------
          ||    0     0     0
```

Note how first transaction in 2015 is not included. Note that this is old period expression, so this bug exsits in master:
```$ hledger balance -f year-test.journal -p 'every 2nd day of month'

Note how 2015 is absent entirely. This is new expression, but i think that general nature of bug is the same...

Older megaparsec is still supported.
Also cleans up our custom parser types,
and some text (un)packing is done in different places
(possible performance impact).

* Revert renaming of parseWithState to parseWithCtx

* Fix doctests

* Update for Megaparsec 5

* Specialize parser to improve performance

* Pretty print errors

* Swap StateT and ParsecT

This is necessary to get the correct backtracking behavior, i.e. discard
state changes if the parsing fails.

In periodic multicolumn balance reports, column headings now show a more
compact description of common periods (years, half-years, quarters,
months, weeks) for better readability and screen space efficiency.

c53732a4af balance: new multi-column reports & documentation 
Two new multi-column balance report modes show ending balance per
period: `--cumulative`, starting from 0, and `--historical`, starting
from the historical starting balance.

The balance command's specification has been clarified and consolidated
in the Balance.hs haddock. Reports.hs has also had haddock updates. The
old AccountsReport type is now BalanceReport, still used by
single-column balance report. The new MultiBalanceReport type is used by
the multi-column reports.
