Two new multi-column balance report modes show ending balance per
period: `--cumulative`, starting from 0, and `--historical`, starting
from the historical starting balance.
The balance command's specification has been clarified and consolidated
in the Balance.hs haddock. Reports.hs has also had haddock updates. The
old AccountsReport type is now BalanceReport, still used by
single-column balance report. The new MultiBalanceReport type is used by
the multi-column reports.
Command line processing has been overhauled and made more consistent,
and now has tests and extensive debug output. More flags now work
both before and after COMMAND: -f, --rule-file, --alias, --help,
--debug, --version. Command line help, command aliases, API docs and
code have been improved.
In general, when cabal CPP macros like min_PKG are used, they should
be made optional. If they are not present, assume a developer is
building and choose the latest libs.
As part of adding -w in december I cleaned up/adjusted register field
widths, and didn't make all the tests pass. This commit makes one more
width adjustment
(one space after the date instead of two) and fixes all tests depending on register output.
Revisiting the "directory 1.2 can be installed with older GHC, so we'd better pin it in the cabal file" change.
Requiring directory 1.2 made hledger-web uninstallable with GHC < 7.6 because current yesod depends on ghc
which depends on a particular directory version and can't be upgraded. This is a smarter fix, which should let
all hledger packages build with whatever directory version is installed.
hledger now requires directory >= 1.2. This might make installation
more complex on old GHC versions; if it turns out to be needed,
perhaps it can be conditionalised again, more accurately, in the cabal file.
- A transaction code may be entered following the date in parentheses, eg: DATE (CODE)
- A transaction comment (possibly containing tags) may be entered following the description, eg: DESC ; COMMENT
- A posting comment may be entered following the amount, eg: AMOUNT ; COMMENT
With one or more command line arguments, they will used as defaults
for the first transaction, and history will be ignored. Subsequent
transactions will use history for defaults (and now only the best match
from history is shown).
- tidier output
- show more help
- suggest . only for recording, not for quitting (though it still works)
- show each transaction after adding it (#52)
- don't parse . as a zero amount
- don't show [] when there's no default
This refactoring fixes an O(n^2) slowdown in the balance command with
large numbers of accounts. It's now speedy, and the implementation is
clearer. To facilitate this, the Account type now represents a tree of
accounts which can easily be traversed up or down (and/or flattened
into a list).

hledger and hledger-web were reading their version number (and program
name) from their cabal files at compile time using cabal-file-th,
which allowed the version number be maintained in one place (per
package).
This meant you had to be in same directory as the cabal file when
building, which made life more complicated, eg emacs compilation mode
could not jump to errors. Also, it slowed down building slightly, and
is a factor in hledger Debian packages being unavailable on a number
of platforms (we also use TH for report templates).
Now, the build version is set with a CPP VERSION flag, which seems
simpler overall. For cabal builds, this needs to be configured
manually in a few more places in each cabal file. For makefile builds,
it is set it to the name of the most recent darcs tag (which should be
more useful than the old behaviour). If not set, it defaults to the
blank string, useful eg for haddock. And, all makefile builds now run
from the top directory.
