hledger - a ledger-compatible text-based accounting tool
========================================================

Welcome to hledger! 

hledger is a haskell clone of John Wiegley's "ledger" text-based
accounting tool (http://newartisans.com/software/ledger.html).  
It generates ledger-compatible register & balance reports from a plain
text ledger file, and demonstrates a functional implementation of ledger.
For more information, see hledger's home page: http://joyful.com/hledger

Installation
------------
hledger requires GHC. It is known to build with 6.8 and 6.10.
If you have cabal-install, do::

 cabal update
 cabal install hledger

Otherwise, unpack the latest tarball from
http://hackage.haskell.org/cgi-bin/hackage-scripts/package/hledger and do::

 runhaskell Setup.hs configure
 runhaskell Setup.hs build
 sudo runhaskell Setup.hs install 

This will complain about any missing libraries, which you can download and
install manually from hackage.haskell.org. The Build-Depends: in
hledger.cabal has the full package list. 

You can configure with optional flags to build additional hledger
features. These are::

  -f vty   - Build vty-based text ui (requires vty, not available on windows)
  -f ansi  - Build ansi-based text ui (requires ansi-terminal)
  -f happs - Build happs-based web ui (requires HApps-Server)

Eg::

 cabal install -f "vty ansi happs" hledger (or runhaskell Setup.hs configure -f "vty ansi happs")

To get the latest development code do::

 darcs get http://joyful.com/repos/hledger


Usage
-----
hledger looks for your ledger file at ~/.ledger by default. To use a
different file, specify it with the LEDGER environment variable or -f
option (which may be - for standard input). Here are some commands to
try::

 hledger --help
 hledger -f sample.ledger balance
 export LEDGER=sample.ledger
 hledger -s balance
 hledger register
 hledger reg cash
 hledger reg -- shop
 hledger ui


Time reporting
--------------
hledger can parse a timelog file in timeclock.el's format, treating
time categories as accounts. If hledger is invoked by the "hours"
alias it looks for your timelog (~/.timelog, or the file specified by
$TIMELOG or -f), and parses arguments slightly differently for
convenient querying::

 hours [OPTIONS] [PERIOD [COMMAND [PATTERNS]]]

PERIOD and COMMAND default to "today" and "balance --subtotal" respectively.
Examples::

 hours                                 # today's balances
 hours today                           # the same
 hours 'this week'                     # so far this week
 hours week                            # the same
 hours lastmonth                       # last month, the space is optional
 hours 'from 1/15'                     # from jan 15
 hours 'monthly in 2008' reg --depth 1 # monthly register, top-level only

Features
--------

This version of hledger mimics a subset of ledger 2.6.1, and adds some
features of its own. We currently support: the balance, print, and
register commands, regular ledger entries, multiple commodities, virtual
transactions, account and description patterns, the LEDGER environment
variable, and these options::

   Basic options:
   -h, --help             display summarized help text
   -v, --version          show version information
   -f, --file FILE        read ledger data from FILE
 
   Report filtering:
   -b, --begin DATE       set report begin date
   -e, --end DATE         set report end date
   -p, --period EXPR      report using the given period
   -C, --cleared          consider only cleared transactions
   -R, --real             consider only real (non-virtual) transactions
 
   Output customization:
   -n, --collapse         balance report: no grand total
   -d, --display EXPR     display only transactions matching EXPR (limited support)
   -E, --empty            balance report: show accounts with zero balance
   -s, --subtotal         balance report: show sub-accounts
 
   Commodity reporting:
   -B, --basis, --cost    report cost basis of commodities

   Commands:
   balance  [REGEXP]...   show balance totals for matching accounts
   register [REGEXP]...   show register of matching transactions
   print    [REGEXP]...   print all matching entries

We handle (almost) the full period expression syntax, and simple display
expressions consisting of a date predicate.  Also the following
hledger-specific features are supported::

   ui,ansi                interactive curses and ansi-based text uis
   web                    rudimentary web interface on port 5000
   --depth=N              balance report: maximum account depth to show

Other differences
.................

* hledger accepts options anywhere on the command line. Instead of - and --
  for pattern negation and separation, use ^ and ^^.
* hledger always keeps differently-priced amounts of the same commodity separate
* hledger calls ledger's "note" field "description"
* hledger doesn't require a space before command-line option values, eg: -f-
* hledger provides "--cost" as a synonym for "--basis"
* hledger's weekly reporting intervals always start on mondays
* hledger shows start and end dates of the intervals requested, not just the span containing data
* hledger period expressions don't support "biweekly", "bimonthly", or "every N days/weeks/..." 
* hledger always shows timelog balances in hours
* hledger doesn't count an unfinished timelog session
