Add documentation and sample output for `--commodity-column` behavior
and functional tests e.g single-period balance, yearly balance, and
yearly budget
This makes it possible to keep multiple named budgets in one journal,
and select the one you want with --budget's argument.
More precisely, you can select the subset of periodic transactions
rules which contain a certain fixed, case-insensitive substring.
Only one such --budget argument is supported, the last one on the
command line takes precedence.
This change provides more predictable and intuitive behaviour when
using -S/--sort-amount with multiple commodities.
It implements a custom Ord (and Eq) instance for MixedAmount
which substitutes zero for any missing commodities.
As a consequence, all the ways of representing zero with a MixedAmount ([],
[A 0], [A 0, B 0, ...]) are now Eq-ual (==), whereas before they were
not. We have not been able to find anything broken by this change.
* imp: lib: Compare MixedAmounts by substituting zero for any missing commodities. (#1563)
* ;doc: Update docs for new multicommodity sort by amount rules.
Multicolumn balance reports showing many commodities tend to become
unreadably wide, especially in tree mode. Now by default we show at
most two commodities, and a count of the rest if there are more than
two. This should help keep reports somewhat readable by default.
This commit introduces the commandline argument -%/--percent to show
percentages of the column's total instead of the absolute amounts for
each account in reports. The signs of the values are preserved.
This option is especially useful for the balance and incomestatement
commands.
If there are multiple commodities involved in a report hledger bails
with an error message. This can be avoided by using --cost. Also note
that if one uses -% with the balance command the chances are high that
all numbers are 0. This is due to the fact that by default balance sums
up to zero. If one wants to use -% in a meaningful way with balance one
has to add a query.
In order to keep the implementation as simple as possible --tree has no
influence over how the percentages are calculated, i.e., the percentages
always represent the fraction of the columns total. If one wants to know
the percentages relative to a parent account, one has to use a query to
narrow down the accounts.
To reduce confusion, multiperiod balance reports using -H/--historical
or --cumulative, which show end balances, no longer show a Totals
column since summing end balances generally doesn't make sense.
Also the underlying MultiBalanceReport now returns zero for those
totals when in cumulative or historical mode.
