We don't need to import Data.Monoid because Prelude.Compat exports "<>"
already. In fact, importing that module causes build failures:
Hledger/Read/Common.hs:725:62: error:
Ambiguous occurrence ‘<>’
It could refer to either ‘Sem.<>’,
imported from ‘Prelude.Compat’ at Hledger/Read/Common.hs:97:1-39
(and originally defined in ‘Data.Semigroup’)
or ‘Data.Monoid.<>’,
imported from ‘Data.Monoid’ at Hledger/Read/Common.hs:110:1-18
Fixes https://github.com/simonmichael/hledger/issues/794.
This also validates transaction date and description upon form submission. As noted in
the issue, this removes hledger-web's "smart date" functionality. This
functionality can be restored giving the demand but should be tracked in
another issue.
Previous iterations used input[type=date], but it isn't easily
crossbrowser and the polyfill I found had some quirks.
I dropped these last month, perhaps without meaning to.
They probably should stay. hledger-ui (eg) will still build
with minor updates of hledger-lib or hledger, but will require
either a release or a hackage revision to build with a major
update.
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).
A few packages which included the Paths_* module no longer do,
and this seems ok with stack and cabal as far as I can tell.
That should be the only change, aside from a bunch of reorderings.
hledger-lib had a valid install plan with GHC 7.8, but requires GHC 7.10 to compile (currently).
Require base 4.8+ everywhere so that stack/cabal will enforce a supported GHC version early.
Also, bump hledger-ui's "stability" to "stable".
