Hledger.Data.Balancing.
Both Hledger.Data.Transaction and Hledger.Data.Journal are massive
module with many things in them. Placing the balancing functions, which
are conceptually related, into a separate module helps keep things more
modular.
It also reduces the risk of import cycles, as right now balancing
functions cannot depend on any functions defined outside of
Hledger.Data.Transaction or Hledger.Data.Journal, respectively, if those
modules require basic transaction or journal functions.
There are no modules which depend on Hledger.Data.Commodity which don't
also depend on Hledger.Data.Amount. Though Hledger.Data.Amount is a very
large module and might be broken up, Hledger.Data.Commodity only defines
three very small functions which are used, and so can be combined with
little cost.
POSIXTime.
This eliminates old-time, which has been deprecated for a while, from
our dependencies.
This introduces a slight incompatibility, as a small number of functions
now take/return POSIXTime instead of ClockTime. Generally you will be
using the current time, in which case you should use getPOSIXTime from
Data.Time.Clock.POSIX instead of getClockTime.
utcTimeToClockTime has been removed, as it is now equivalent to
utcTimeToPOSIXSeconds from Data.Time.Clock.POSIX.
We officially support GHC 8.6+ (and 8.8+ for hledger-web) now.
Hackage matrix builder shows all packages building successfully
with GHC 8.4+, somehow, so we'll adjust the base bound to
allow that but prevent any attempts to build with older GHCs,
functions to AccountTransactionsReport.
If you use transactionsReport, you should either use entryReport if you
don't require a running total, or using accountTransactionsReport with
thisacctq as Any or None (depending on what you want included in the
running total).
Prior to this commit,
- hledger still builds with GHC 8.0
- hledger-ui does if you use the build plan specified by stack8.0.yaml,
but you are likely to hit problems if you let cabal pick one
(https://github.com/jtdaugherty/vty/issues/198 and others)
- hledger-web might, if you could find the right build plan
The hassles are enough and GHC 8.0 is old enough (first released in
2016) that I'm letting it go; 8.2 is the new minimum version for all
hledger packages.
This allows a bunch of cleanups to conditional imports, which I leave
for later.
Also, updated the tested-with minor versions.
Decimal 0.5.1+ changed to banker's rounding (round to nearest even
number), and math-functions 0.3.3.0 (used by roi) fixed various
precision-related issues. Now we require the latest versions of these.
This was causing some functional test failures when building with old
GHCs/snapshots.
easytest is not actively maintained and requires an old version of
hedgehog which does not support base-compat 0.11 & ghc 8.8.
This is still using the old easytest helpers, and not displaying test
names properly.
in JournalReader.hs. If you still need this, feel free to work on
those errors. But hopefully not, because dropping base 4.8 should
permit some code cleanups.
by default. hledger-lib's doctests and easytests test suites (each ?)
require an additional slow rebuild of hledger-lib and are not worth
the time, energy and carbon. hledger's test suite runs those same
easytest tests (but not the doctests).
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
This constraints the easytest dependency to <0.3, because hledger and
hledger-lib currently don't build with 0.3.
Of course the better solution would be to fix the build errors, but easytest-0.3
is not even in stackage nightly yet and I just need it to build right now :-)
