instead of a list of Amounts. No longer export Mixed constructor, to keep API clean (if you really need it, you can import it directly from Hledger.Data.Types). We also ensure the JSON representation of MixedAmount doesn't change: it is stored as a normalised list of Amounts. This commit improves performance. Here are some indicative results. hledger reg -f examples/10000x1000x10.journal - Maximum residency decreases from 65MB to 60MB (8% decrease) - Total memory in use decreases from 178MiB to 157MiB (12% decrease) hledger reg -f examples/10000x10000x10.journal - Maximum residency decreases from 69MB to 60MB (13% decrease) - Total memory in use decreases from 198MiB to 153MiB (23% decrease) hledger bal -f examples/10000x1000x10.journal - Total heap usage decreases from 6.4GB to 6.0GB (6% decrease) - Total memory in use decreases from 178MiB to 153MiB (14% decrease) hledger bal -f examples/10000x10000x10.journal - Total heap usage decreases from 7.3GB to 6.9GB (5% decrease) - Total memory in use decreases from 196MiB to 185MiB (5% decrease) hledger bal -M -f examples/10000x1000x10.journal - Total heap usage decreases from 16.8GB to 10.6GB (47% decrease) - Total time decreases from 14.3s to 12.0s (16% decrease) hledger bal -M -f examples/10000x10000x10.journal - Total heap usage decreases from 108GB to 48GB (56% decrease) - Total time decreases from 62s to 41s (33% decrease) If you never directly use the constructor Mixed or pattern match against it then you don't need to make any changes. If you do, then do the following: - If you really care about the individual Amounts and never normalise your MixedAmount (for example, just storing `Mixed amts` and then extracting `amts` as a pattern match, then use should switch to using [Amount]. This should just involve removing the `Mixed` constructor. - If you ever call `mixed`, `normaliseMixedAmount`, or do any sort of amount arithmetic (+), (-), then you should replace the constructor `Mixed` with the function `mixed`. To extract the list of Amounts, use the function `amounts`. - If you ever call `normaliseMixedAmountSquashPricesForDisplay`, you can replace that with `mixedAmountStripPrices`. (N.B. this does something slightly different from `normaliseMixedAmountSquashPricesForDisplay`, but I don't think there's any use case for squashing prices and then keeping the first of the squashed prices around. If you disagree let me know.) - Any remaining calls to `normaliseMixedAmount` can be removed, as that is now the identity function. |

hledger project README
lightweight, portable, dependable accounting tools
hledger is a computer program for easily tracking money, time, or other commodities, on unix, mac and windows (and web-capable mobile devices, to some extent).
It is first a command-line tool, but there are also terminal and web interfaces, and a Haskell library for building your own programs and scripts (hledger is written in Haskell). hledger was inspired by and is largely compatible with Ledger. hledger is free software available under the GNU General Public License v3+.
hledger aims to help both computer experts and regular folks to gain clarity and control in their finances and time management, but currently it is a bit more suited to techies. I use it every day to:
- track spending and income
- see time reports by day/week/month/project
- get accurate numbers for client billing and tax filing
- track invoices
Though limited in features, hledger is lightweight, usable and reliable. For some, it is a simpler, less distracting, more future-proof alternative to Quicken or GnuCash.
