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".
Generated package.yaml files from the old cabal files with hpack-convert,
removed some problematic blank lines manually,
regenerated the cabal files from the package.yaml files with hpack.
Tests pass, looks like all the info is still there.
This means that from now on, we don't edit cabal files directly.
We edit the less verbose package.yaml files. stack will update
the cabal files automatically (or non-stack users can use hpack).
The changes to both are committed, as we still want to provide
the cabal files to downloaders.
* Replace Parsec with Megaparsec (see #289)
This builds upon PR #289 by @rasendubi
* 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.
