d7b68fbd7d Use skipMany/skipSome for parsing spacenonewline 
This avoids allocating the list of space characters only to then
discard it.

d7d5f8a064 add support for megaparsec 6 (fixes #594) 
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).

b6ff170688 lib: simplify format detection, avoid ledger reader by default 
When we don't know a file's format, instead of choosing a subset of
readers based on content sniffing, now we just try them all.
Also, LedgerReader is now used only as a last resort,
as it's not yet competitive with JournalReader.

4ceda8f985 timeclock: fix order of transaction indexes #394 
Timeclock transaction ids now count up rather than down.

Also, remove old code for appending timeclock transactions to journal transactions,
a holdover from the days when both were allowed in one file.

4141067428 Replace Parsec with Megaparsec (see #289) (#366) 
* 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.

Slightly higher (with small files) and lower (with large files) maximum
residency, and slightly quicker for all.

2538d14ea7 lib: textification begins! account names 
The first of several conversions from String to (strict) Text, hopefully
reducing space and time usage.

This one shows a small improvement, with GHC 7.10.3 and text-1.2.2.1:

0f5ee154c4 lib: simplify parsers; cleanups (#275) 
The journal/timeclock/timedot parsers, instead of constructing (opaque)
journal update functions which are later applied to build the journal,
now construct the journal directly (by modifying the parser state). This
is easier to understand and debug. It also removes any possibility of
the journal updates being a space leak. (They weren't, in fact memory
usage is now slightly higher, but that will be addressed in other ways.)

Also:

Journal data and journal parse info have been merged into one type (for
now), and field names are more consistent.

The ParsedJournal type alias has been added to distinguish being-parsed
and finalised journals.

Journal is now a monoid.

stats: fixed an issue with ordering of include files

journal: fixed an issue with ordering of included same-date transactions

timeclock: sessions can no longer span file boundaries (unclocked-out
sessions will be auto-closed at the end of the file).

expandPath now throws a proper IO error (and requires the IO monad).

84097b75c7 journal: can now include timeclock/timedot files (#320) 
journal files can now include journal, timeclock or timedot files (but
not yet CSV files). Also timeclock/timedot files no longer support
default year directives.

The Hledger.Read.* modules have been reorganised for better reuse.
Hledger.Read.Utils has been renamed Hledger.Read.Common and holds
low-level parsers & utilities; high-level read utilities have moved to
Hledger.Read.
