[Haskell] ANN: hledger 0.19

[Simon Michael]

I'm pleased to announce the release of hledger 0.19! This release has just two visible changes: a much faster balance command, and support for the latest GHC and libs. (A hledger-web update will follow.)

hledger is a command-line tool and haskell library for tracking financial transactions, which are stored in a human-readable plain text format. In addition to reporting, it can also help you record new transactions, or convert CSV data from your bank. Add-on packages include hledger-web, a web interface. hledger is inspired by and compatible with John Wiegley's Ledger. For more, see http://hledger.org .

Install it:

cabal update; cabal install hledger . For installation help, see http://hledger.org/MANUAL.html#installing . Or, sponsor a ready-to-run binary for your platform: http://hledger.org/DOWNLOAD.html .

Release notes:

hledger, hledger-lib: support GHC 7.6 and latest cmdargs, haskeline, split

balance report no longer has an O(n^2) slowdown with large numbers of accounts, and is generally more speedy. Benchmark on a 2010 macbook:
