My pleasure, Vladimir. I was going to tell you about -T a, but I
noticed that it deviated from your desired output in one important way:
the final total amount is always zero---even when it shouldn't be.
For example (using my personal ledger file):
## Regular run
$ ledger -p 'this week' bal expenses | tail -n 1
$281.38
## With -T a
$ ledger -p 'this week' bal expenses -T a | tail -n 1
0
## With -T '(l==0)?O:a'
$ ledger -p 'this week' bal expenses -T '(l==0)?O:a' | tail -n 1
$281.38
Ledger seems to consider the final total a top-level account (depth
equaling zero), so it will probably always calculate to zero with 'a'.
The value expression '(l==0)?O:a' tests for that and uses the regular
value expression, 'O', for the total and 'a' for the rest of the
accounts.
But if you don't need that final total, "-T a" is sure a lot easier
to remember!
