Hello,
I've recently been trying to write an importer script and was trying to
use a Custom directive. There isn't a lot of documentation on this, and I haven't
been able to figure out what the problem is from the source, and was
wondering if anyone here had any ideas. I'm not sure if I'm using
beancount.core.data.Custom wrong or if you're supposed to use a
different object entirely.
Issue occurs when there is a beancount.core.data.Custom object in the
list returned by the extract() function
[...]
ret.append(data.Custom(meta, date, "example", ["value1", "value2", "value3"]))
The fourth field in a beancount.core.data.Custom() object is a list of
beancount.parser.grammar.ValueType() instances. ValueType() instances
are initialized with a value and a data type (a Python class).
Therefore, your code should read something like:
ret.append(data.Custom(
meta, date, "example", [
grammar.ValueType("value1", str),
grammar.ValueType("value2", str),
grammar.ValueType("value3", str),
])
)
An easy way to figure out this kind of things is to run the parser on
the Beancount format representation of the directive you want to obtain:
from beancount.parser import parser
entries, errors, options = parser.parse_string(
'''2024-02-17 custom "example" "value1" "value2" "value3"'''
)
print(entries)
Cheers,
Dan
