Previously, a depth:0 query produced an empty report (since there are no
level zero accounts). Now, it aggregates all data into one summary item
with account name "...".
This makes it easier to see the kind of data Gwern was looking for from
register-csv (net worth over time). Eg this shows one line per month
summarising the total of assets and liabilities:
hledger register-csv -- -MHE ^assets ^liabilities depth:0
Single and multi-column balance reports behave similarly.
multicolumn balance reports only show accounts with activity (postings)
during the report period, by default. Sometimes you want to show
accounts which have an interesting balance, even if they have no
activity during the period. -E now does this, in addition to showing
leading & trailing empty columns.
Previously, the first period's heading would show the start date of a
full period, but postings after this date but before the user-specified
report start date were not shown. Now those postings will be included,
making the first column's numbers more correct. Similarly, the report
end date is now adjusted to the displayed end date on the last column.
Periodic, cumulative and historical multicolumn balance reports are now
generated by one code path, which helps with consistency and reducing
the bug/test surface. --tree now also works with --cumulative or
--historical.
Multicolumn balance reports can now be switched to a hierarchical view
with --tree. This is similar to the single column balance report with
--no-elide, ie we do not elide boring parents into the following line.
The --flat and --tree flags are opposites; the last one to appear on
the command line is decisive (in future, if not already).
Changes include:
- flat mode now shows exclusive (subaccount-excluding) balances.
This is a deviation from ledger, but seems simpler and clearer
for users and implementors across the various modes.
- in flat mode, --depth now aggregates deeper accounts at the
depth limit, rather than just excluding them from the report.
This is more useful.
- in flat mode, --empty no longer shows parent accounts with
no postings.
- more tests, more debug output, clearer code
