c5561f25f1 lib: switch parsers to the custom error type 
Also add an explicit export list to `hledger-lib/Hledger/Utils/Parse.hs`
in order to re-export the custom error type (for convenience).

ca201e4618 lib: add a module for custom parse errors 
... 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.

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

48623b4ceb lib: fix backtracking in periodexpr parser 
- Simplify doctests for periodexpr.
- Besides consuming leading space consume ending space for periodexpr also.
- Drop implicit option (def, def) behaviour of periodexpr. I.e. disallow
  hledger reg -p '' and auto-transaction with heading just '~'.
- Slightly re-factor periodexpr.
- Ensure that reportinginterval doesn't consume trailing space.
  Useful if  we'll start disallowing periods like "every1stjan2009-".

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).

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.

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:

5b5e5eeaf4 register: wide-character-aware layout (#242) 
Wide characters, eg chinese/japanese/korean characters, are typically
rendered wider than latin characters. In some applications (eg gnome
terminal or osx terminal) and fonts (eg monaco) they are exactly double
width. This is a start at making hledger aware of this. A register
report containing wide characters (in descriptions, account names, or
commodity symbols) should now align its columns correctly, when viewed
with a suitable font and application.

cc98ee39f7 balance, lib: --format/StringFormat improvements 
The balance command's --format option (in single-column mode) can now
adjust the rendering of multi-line strings, such as amounts with multiple
commodities. To control this, begin the format string with one of:

 %_  - renders on multiple lines, bottom-aligned (the default)
 %^  - renders on multiple lines, top-aligned
 %,  - render on one line, comma-separated

Also the final total (and the line above it) now adapt themselves to a
custom format.
