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.
The regex helpers were converting strings to regex-tdfa regular
expressions on the fly every time, but this appears to be quite
expensive. The simplest memoisation lib seems to solve it nicely.
hledger-lib-0.24's "track the commodity of zero amounts when
possible (useful eg for hledger-web's multi-commodity charts)" preserved
the commodity when normalising a zero mixed amount, but not the amount
style. This showed up as occasionally incorrect amount style (commodity
symbol placement, decimal point character, etc.) in balance reports with
certain journals, like this:
$ hledger bal
€3000.00 a <------ not using the canonical € style
4000,58€ 1
-1000,58€ D
-3000,00€ e
--------------------
0
I thought this would require a big rewrite of amount arithmetic, but it
seems that just being a little more careful is enough. When normalising
a mixed amount containing multiple zeros in the same commodity, we now
preserve the last zero with its amount style, instead of replacing them
all with a new one.
Make these modules' names more like the heavily-used types they
define (CliOpts, UIOpts, WebOpts). This is consistent with
RawOptions and ReportOptions, and helps with code navigation.
To reduce noise in the "other accounts" field of hledger-ui's and
hledger-web's account register: if there are both real and virtual
postings to other accounts, show only the accounts posted to by real
postings.
Use case: in many transactions I have extra balanced-virtual postings
which adjust budget envelopes (subaccounts of checking). These clutter
up the register's other accounts field making it useless. Excluding them
(when there are also real postings) makes it more useful for me and
probably others.
The register screen is now like the register view in hledger-web (and
other accounting systems), rather than hledger's register command.
This means:
- it shows transactions affecting a particular current account, rather
than postings matching a pattern.
- Each line represents a whole transaction.
- The account field shows the *other* account being transacted with.
When there is more than one, they are all listed, abbreviated and
marked with "(split)".
- The amount field shows the effect of the transaction on the current
account; positive for an inflow to this account, negative for an
outflow.
- The balance field should usually show the current account's historic
balance as of the transaction date, even when you change the report
start date. (Not working yet - currently it always shows the running
total).
- Transactions are listed most recent first, currently.
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.
The --format option's OutputFormat type was named confusingly like the
--output-format option. It has been renamed StringFormat to distinguish
it from StorageFormat (aka the data file format, referenced by
--output-format). Related code and types have been consolidated.
Also the (single-column) balance report's item rendering has had
some cleanup.
so we can benchmark things more easily with criterion.
As well as NFData, the Generic instance and a bunch more GHC extensions
seemed necessary. This is a little scary, impact unknown.
Simpler and clearer. We now have "transaction prices" (recorded as part
of transaction amounts) and "market prices" (recorded with P
directives). Both are matters of historical record, also this avoids
confusion with the balance command's "historical balances".
Initial support of market value reporting and currency conversion,
similar in spirit to Ledger's. The balance command now has a -V/--value
flag that converts all the reported amounts using their "default market
price". That is the latest market price (P directive, formerly called
"historical prices") found in the journal for their commodity that is on
or before the report end date.
Unlike Ledger, hledger's -V only uses the market prices recorded with P
directives, ignoring transaction prices recorded as part of posting
amounts (which -B/--cost uses). Using -B and -V together is allowed.
Here are hpack package.yaml files for the other hledger cabal files.
These remove a lot of human-error-prone duplication.
They are not used yet as hpack isn't quite mature enough -
when it supports flags and benchmarks we will probably switch.
