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.
On the accounts screen, the g key now reloads the journal if possible.
With large journals, there may be a noticeable delay before the screen updates.
If there's a problem reading the journal file(s), this has no effect.
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.
This was originally an add-on I used to guess account names for
ledger-autosync. It's nice for quickly looking up a recent transaction
with a guessed or partial description.
In some cases (when the same letter pair was repeated) it was not
picking the post similar past transaction. This was due to the
similarity algorithm using the order-dependent Data.List.intersect, when
it should use Set.intersection.
Also added a reference for the algorithm, which is known as the
Sørensen–Dice coefficient.
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.
