This PR #1330, addressing #1312 (parseQuery is partial) and #1245
(internal server error).
User-visible changes:
- hledger-web now handles malformed regular expressions
(eg, a query consisting of the single character `?`) gracefully,
showing a tidy error message instead "internal server error".
API/internal changes:
- The Regex type alias has been replaced by the Regexp ADT, which
contains both the compiled regular expression (so is guaranteed to
be usable at runtime) and the original string (so can be serialised,
printed, compared, etc.) A Regexp also knows whether is it case
sensitive or case insensitive. The Hledger.Utils.Regex api has changed.
- Typeable and Data instances are no longer derived for hledger's
data types; they were redundant/no longer needed
- NFData instances are no longer derived for hledger's data types.
This speeds up a full build by roughly 7%. But it means we can't
deep-evaluate hledger values, or time hledger code with Criterion.
https://github.com/simonmichael/hledger/pull/1330#issuecomment-684075129
has some ideas on this.
- Query no longer has a custom Show instance
- Some internal use of regexps was replaced by text replacement or
parsers.
- Hledger.Utils.String: quoteIfNeeded now actually escapes quotes in
strings; dropped escapeQuotes
- Hledger.Utils.Tree: dropped some old utilities
- dropped some obsolete code for the old --display option

;areg: debug output
;areg: show a title indicating which account was picked
This might be a bit of a pain for scripting, but otherwise it can be
quite confusing if your argument matches an account you didn't expect.
;areg: improve CSV headings
;areg: show at most two commodities per amount
accountTransactionsReport now filters transactions more thoroughly, so
eg transactions dated outside the report period will not be shown.
Previously the transaction would be shown if it had any posting dated
inside the report period. Possibly some other filter criteria now get
applied that didn't before. I think on balance this will give slightly
preferable results.
bal --budget was always showing the period as column heading,
as if for a change report. With --cumulative or --historical
it should show the end date, like other balance reports. Cf
https://hledger.org/hledger.html#multicolumn-balance-report.
This is an API change, but it seems better than having additional
colour-supporting variants and trying to avoid duplicated code.
I stopped short of changing showAmount, so cshowAmount still exists.
