beancount-docverif 0.1.1

Document verification plugin for Beancount

Beancount Docverif

Docverif is the "Document Verification" plugin for beancount, fulfilling the following functions:

1. Require that every transaction touching an account have an accompanying document on disk:

   2000-01-01  open  Expenses:General BEAN
     docverif: "Require"
   

2. Explictly declare the name of a document accompanying a transaction:

   ; Document entry pointing to a working document: should validate correctly
   2020-06-01  *   "plumber"   "fix faucet leak"
     document: "2020-06-01.plumber - services.pdf"
     Expenses:General
     Assets:Bank -150 BEAN
   

3. Explicitly declare that a transaction is expected not to have an accompanying document:

   ; Explicit "None" document: should ignore missing document
   2020-06-01  *   "store" "groceries"
     document: "None"
     Expenses:General
     Assets:Bank -10 BEAN
   

4. Look for an "implicit" PDF document matching transaction data:

   ; Document entry without an explicit "document" entry,
   ; should implicitly match document: "2020-06-01.plumber - services.pdf"
   2020-06-01  *   "plumber"   "services"
     Expenses:General
     Assets:Bank -150 BEAN
   

5. Associate (and require) a document with any type of entry, including open entries themselves:

   2000-01-01  open    Assets:Bank BEAN
     docverif: "Require"
     document: "2020-06-01.plumber - services.pdf"
   

6. Guarantee integrity: verify that every document declared does in fact exist on disk.

See sanitize.sh for maintainer's personal tooling.

Beancount Quirks

1. We depend on beancount itself finding documents and auto-generating Document entries. This requires a documents option in the beancount file itself, eg:

   option "documents" "./"
   

2. Subdirectory format TODO

3. Fictitious TODO

4. Filename must be valid (eg. "broken.pdf" is out)
