I'm struggling to get my head around how to write value expressions with
respect to automatic transactions
#+BEGIN_EXAMPLE
= /^Liabilities:CrushingDebt/ and (d > [2014/04/15])
Assets:Checking 0.5
Assets:RichUncle -0.5
2014/04/01 * Foo
Liabilities:CrushingDebt $100
Assets:Checking
2014/04/25 * Bar
Liabilities:CrushingDebt $150
Assets:Checking
2014/04/25 * Unrelated
Liabilities:TolerableDebt $100
Assets:Gubment
#+END_EXAMPLE
I'm getting:
ledger -f example.ledger bal
#+BEGIN_EXAMPLE
$-400 Assets
$-125 Checking
$-150 Gubment
$-125 RichUncle
$400 Liabilities
$250 CrushingDebt
$150 TolerableDebt
--------------------
0
#+END_EXAMPLE
I was hoping for
#+BEGIN_EXAMPLE
$-400 Assets
$-175 Checking
$-150 Gubment
$-75 RichUncle
$400 Liabilities
$250 CrushingDebt
$150 TolerableDebt
--------------------
0
#+END_EXAMPLE
Pointers on how one debugs this sort of thing would be appreciated too. I
tried "--trace", but below 10 gives me no interesting information and above 9
caused a segfault with the error:
#+BEGIN_EXAMPLE
terminate called after throwing an instance of 'std::logic_error'
what(): Argument to --trace must be an integer
#+END_EXAMPLE
The ledger parse stuff seems to use a different syntax from the automatic
stuff, as if I do a
ledger parse "d>[2004/05/15]"
#+BEGIN_EXAMPLE
--- Context is first posting of the following transaction ---
2004/05/27 Book Store
; This note applies to all postings. :SecondTag:
Expenses:Books 20 BOOK @ $10
; Metadata: Some Value
; Typed:: $100 + $200
; :ExampleTag:
; Here follows a note describing the posting.
Liabilities:MasterCard $-200.00
--- Input expression ---
d>[2004/05/15]
--- Text as parsed ---
(d > [2004/05/15])
--- Expression tree ---
0xb6e710 O_GT (1)
0xb6e760 IDENT: d (1)
0xb6e860 VALUE: [2004/05/15] (1)
--- Compiled tree ---
0xb6c0f0 O_GT (1)
0xb6bcb0 IDENT: d (1)
0xb6bc60 FUNCTION (1)
0xb6e860 VALUE: [2004/05/15] (1)
--- Calculated value ---
true
#+END_EXAMPLE
It actually parses the date like I would expect, but the =/^Liabilities/ fails
ledger parse "=/^Liabilities/"
#+BEGIN_SRC
--- Context is first posting of the following transaction ---

#+END_EXAMPLE
Hopefully this is enough information for someone to help me in my
misunderstanding...
