- expands the set of expected tokens when e.g. parsing the invalid
posting `account $1 a`
- whitespace can affect parse errors because of the longest match rule
where errors that occur later take precedence over those that occur
earlier
- inline `spaceamountormissingp` into `postingp`
- combine `rightsymbolamountp` and `nosymbolamountp`
- the multiplier symbol '*' for an amount must now always preceed a sign '-'
[breaking change]
- make amount parser labels more generic to simplify error messages
It's amazing how you can build, document, support and fix a thing for
years and not know what exactly it does. Directives are tricky.
Here is a pretty accurate description of their current behaviour,
determined by testing.
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
... for displaying the source line on which parse errors occured
Over the following set of commits, I will to refactor the parsers to
obviate the `ExceptT String` layer of the `ErroringJournalParser` type
so that all parse errors go through Megaparsec's parse error machinery.
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.
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.
