question about "account_rounding"

[llpa...@gmail.com]

The way I understand the documentation, a test.beancount file with content:

plugin "beancount.plugins.auto_accounts"
option "account_rounding" "Equity:Rounding-Errors"
option "inferred_tolerance_default" "USD:0.01"
2018-01-01 * "buy one apple"
  Assets:Account:APPLE 1 APPLE {1.0 USD}
  Assets:Account:Cash -0.99 USD

Should translate by "bean-query test.beancount print" to:

plugin "beancount.plugins.auto_accounts"
option "account_rounding" "Equity:Rounding-Errors"
option "inferred_tolerance_default" "USD:0.01"
2018-01-01 * "buy one apple"
  Assets:Account:APPLE 1 APPLE {1.0 USD}
  Assets:Account:Cash -0.99 USD
  Equity:Rounding-Errors -0.01 USD

However, it doesn't work. What am I missing?

A couple of things:

1.

You have to specify the subaccount  name only:

2.

About the feature: it looks like I must have stripped it accidentally when removing the old version of the booking code.

Surprised it's not coming up before your reporting of it because I know some people are using it.

I'm not using the feature myself, and somehow I didn't put a unit test for it (beyond that of Ledger conversion, which is the context in which it came about).

They must be using it through its hardcoded conversion to Ledger (which requires it):

I am also finally working on entering my mutual funds, and finding out the numbers from my mutual fund don't add up and cause "Transaction does not Balance" errors.  I found the Saving Rounding Error entry in the Precision and Tolerances docs, and thought the automatically adding the makeup posting was a neat feature.  Aside from enabling the feature with "option "account_rounding" "Equity:RoundingError"", I didn't see how to "automatically add" the posting. I didn't find the docs where llpa (name on post above) mentions the auto_accounts plugin needs to be added, and bean-query adds the postings. I did find another posting here Beancount Updates - 2015-12-13) that mentions the "Equity:" does not need to be used. I look forward to trying out the featuer when it is added back in.
