Hledger.Util.Tests helpers have been cleaned up, and test names are
now shown.
Tests have been cleaned up a bit. Some groups of unnamed tests have
been collapsed into a single named test containing a sequence of
assertions. The test command counts named tests, not assertions, so
the reported unit test count has dropped from 199 to 188.
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.
This feature turns out to be quite involved, as valuation interacts
with the many report variations. Various bugs/specs have been
fixed/clarified relating to register's running total, balance totals
etc. Eg register's total should now be the sum of the posting amount
values, not the values of the original sums. Current level of support
has been documented.
When valuing at transaction date, we once again do early valuation of
all posting amounts, to get more correct results. variants. This means
--value-at=t can be slower than other valuation modes when there are
many transactions and many prices. This could be revisited for
optimisation when things are more settled.
We need this for choosing a valuation date, otherwise, report
functions would have to be in IO or we'd have to pass in yet another
argument.
It's optional because it's useful to be able to create report opts
purely (I think ?) This is not ideal but maybe not a problem.
Income, liability and equity balances, which until now we have
always displayed as negative numbers, are now shown as normally positive
by these reports.
Negative numbers now indicate a contra-balance (eg an overdrawn
checking account), a net loss, a negative net worth, etc.
This makes these reports more like conventional financial statements,
and easier to read and share with normal people.
