I'm trying to figure out whether I can use the Beangulp import driver
with hooks, or if I need to write my own driver to call my importers and
do postprocessing. As you may recall, my workflow is atypical, as I
have no curated Beancount ledger file; my source of truth are my input
data files and the Beancount ledger is a built artifact for running
analysis.
There are two things I'd like to do that I don't think are currently
possible; I'd appreciate feedback on whether these seem like things
Beangulp should support (I could contribute a patch), or if I'm better
off finding a different solution:
- I'd like to deduplicate entries among different importers in a single
run, not just dedup against a pre-existing ledger
I was going to reply that this is already supported, then I realized
that I never merged the patch implementing it
https://github.com/beancount/beangulp/pull/64 I'm going to rebase and
merge it ASAP.
- I'd like to be able to emit the output file globally sorted by date
(first the official entry date, then secondarily by a timestamp attached
to the metadata) rather than grouped by import file. (Broadly this will
make it easier for me to debug issues sequentially, and ordering
within-day may alleviate some of the issues I've seen with same-day
purchase & transfer transactions.)
It is trivial to post-process the output of beangulp to apply any
ordering you like. Indeed I do something very similar for ledgers.
Writing from memory:
import beanquery.parser.parser
import beanquery.parser.printer
def key(entry):
return (entry.date, entry.meta['timestamp'])
entries, errors, options = parser.parse_file(filename)
entries.sort(key=key)
printer.print_entries(entries)
And just to double check that this should already be possible:
- I'd like to be able to add entries (i.e., account declarations,
initial balance pads, etc.) via a hook
You can do this as part of the sorting post-processing step, or with a
beancount plugin. See for example the beancount.plugins.auto_accounts
(and other) plugins.
Cheers,
Dan
