Sometimes trailing empty fields are omitted entirely (including the
commas) in CSV records. (I see this in exported Google spreadsheets.)
Now we don't raise an error in this case, instead we automatically pad
any "short" records with empty fields. Not yet well tested.
And if they did, the stats command would now throw an error.

journalApplyCommodityStyles
journalInferCommodityStyles

fail is moving out of Monad and into it's own MonadFail class.
This will be enforced in GHC 8.8 (I think).
base-compat/base-compat-batteries 0.11.0 have adapted to this,
and are approaching stackage nightly
(https://github.com/commercialhaskell/stackage/issues/4802).
hledger is now ready to build with base-compat-batteries 0.11.0, once
all of our deps do (eg aeson). We are still compatible with the older
0.10.x and GHC 7.10.3 as well.
For now we are using both fails:
- new fail (from Control.Monad.Fail), used in our parsers, imported
via base-compat-batteries Control.Monad.Fail.Compat to work with
older GHC versions.
- old fail (from GHC.Base, exported by Prelude, Control.Monad,
Control.Monad.State.Strict, Prelude.Compat, ...), used in easytest's
Test, since I couldn't find their existing fail implementation to update.
To reduce (my) confusion, these are imported carefully, consistently,
and qualified everywhere as Fail.fail and Prelude.fail, with clashing
re-exports suppressed, like so:
import Prelude hiding (fail)
import qualified Prelude (fail)
import Control.Monad.State.Strict hiding (fail)
import "base-compat-batteries" Prelude.Compat hiding (fail)
import qualified "base-compat-batteries" Control.Monad.Fail.Compat as Fail
Errors involving a record like:
2000-01-01,a,"1"
displayed the record with extra spaces:
the CSV record is: "2000-01-01", "a", "1"
which was not accurate or valid RFC-4180.
dropped journalPrices
renamed Price to AmountPrice, AKA "transaction price"
renamed MarketPrice to PriceDirective.
added new MarketPrice (more pure form of PriceDirective without the amount style information)
Prices is now a more efficient data structure, but not used yet.
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.
