# hledger-simplebal [BALANCEARGS] - try to reliably report the grand

# Tired of complex financial reports ? This is a silly but fun and
|
|
# occasionally useful script showing how to get "one number" semi-robustly
|
|
# without writing a haskell script. With this installed in PATH, then eg:
|
|
#
|
|
# $ hledger number lodging
|
|
# 200
|
|
#
|
|
# Explanation:
|
|
# -0 (--depth 0) hides all but top-level accounts
|
|
# -N (--no-total) hides the totals line
|
|
# -X COMM (--value=end,COMM) converts to a single commodity if possible (needs at least one suitable P market price declaration)
|
|
# --infer-market-prices guesses P price from conversion transactions if necessary
|
|
# -c (--commodity-style) sets a predictable number format free of thousands separators
|
|
# --layout=bare moves the commodity symbol away from the number
|
|
# awk discards all but the number
|
|
#
|
|
# A note: If you're new to hledger/PTA and thinking it shouldn't be this hard..
|
|
# well of course normally when a hledger user wants to see a single balance,
|
|
# they run a much simpler command like `hledger bal lodging`. This script is
|
|
# exploring how to anticipate and neutralise all variations from account
|
|
# structure, number formatting, multiple commodities, etc. so as to *reliably*
|
|
# produce *one machine readable number* from highly diverse data. As we figure
|
|
# out good approaches we'll build them in so that producing data for charting
|
|
# (eg) is as easy as it can be, while still being general.
