Bracketed posting dates were fragile; they worked only if you wrote full
10-character dates. Also some semantics were a bit unclear. Now they
should be robust, and have been documented more clearly. This is a
legacy undocumented Ledger syntax, but it improves compatibility and
might be preferable to the more verbose "date:" tags if you write
posting dates often (as I do).
Internally, bracketed posting dates are no longer considered to be tags.
Journal comment, tag, and posting date parsers have been reworked, all
with doctests. Also the journal parser types generally have been
tightened up and clarified, making it much easier to know how to combine
and run them. There's now
-- | A parser of strings with generic user state, monad and return type.
type StringParser u m a = ParsecT String u m a
-- | A string parser with journal-parsing state.
type JournalParser m a = StringParser JournalContext m a
-- | A journal parser that runs in IO and can throw an error mid-parse.
type ErroringJournalParser a = JournalParser (ExceptT String IO) a
and corresponding convenience functions (and short aliases) for running them.
We now parse account directives, like Ledger's. We don't do anything
with them yet. The default parent account feature must now be spelled
"apply account"/"end apply account".
The Journal, Timelog and Timedot readers' detectors now check
each line in the sample data, not just the first one. I think
the sample data is only about 30 chars right now, but even so
this fixed a format detection issue I was seeing.
Timedot is a plain text format for logging dated, categorised
quantities (eg time), supported by hledger. It is convenient for
approximate and retroactive time logging, eg when the real-time
clock-in/out required with a timeclock file is too precise or too
interruptive. It can be formatted like a bar chart, making clear at a
glance where time was spent.
Amount display style canonicalisation code and terminology has been
clarified a bit. Individual amounts still have styles; from these we
derive the standard "commodity styles". In user docs, we might call
these "commodity formats" since a Ledger-compatible commodity directive
would use the "format" keyword.
I really don't see why that extra x parameter is needed or works..
rewrite it in simpler form.
I also might be introducing breakage for older GHC's by using
unconditionally <$>, but I'm not seeing that for some reason
(tested back to ghc 7.6).
Since market price amounts didn't contribute to the canonical commodity
styles, they were being reset to the null style. And this propagated to
the reported amounts when -V was in effect, causing much confusion.
Now, market prices contribute to canonicalisation and the expected
styles are preserved even with -V.

print now always right-aligns the amounts in an entry, even when they
are wider than 12 characters.
If there is a price, it's considered part of the amount for
right-alignment. Maybe it would be nicer to put amounts and prices in
separate columns ? That will get a little complicated, needs more
discussion/design.
Also some cleanup of postingAsLines.
The print command wasn't lining up amounts with wide chars in account
names, fixed it properly this time. Transaction and Posting's Show instances
should also be wide-char-aware now.
Simple (non-multicolumn) balance reports containing wide characters
should now align correctly (in apps and fonts that show wide chars as
double width). Likewise, the print command.
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.
This adds a accountNameApplyAliasesMemo, which memoises the result of
applying a set of aliases (simple and regex) to an account name. In
theory this should reduce more repetitive work, but in practice it
doesn't seem to make a difference, so it's unused for now.
Roughly speaking, the time to apply regular expression account aliases
was O(aliases x transactions), and should now be O(aliases x accounts).
Also, the constant factor was reduced a lot by the recent commit
memoising toRegex. So now, regex aliases should be "free" like simple
aliases - use as many as you want, the slowdown shouldn't be noticeable.
