The different namespaces are:
Function Value expression functions, which receive a "context"
Option Command-line options
Precommand Commands which are invoked before reading the journal
Command Commands which are invoked after reading the journal
Directive Directives that occur at column 0 in a data file
This greatly eases the ability for Python uses to add intercept hooks to
change how the basic Ledger module functions. An example of what should
be possible soon:
import ledger
def my_foo_handler(value):
print "--foo received:", value
ledger.add_handler(ledger.Option, "foo=", my_foo_handler)
The problem at this point is that it's recording prices in the price
database multiple times; it should only need to download a price for
each commodity once per day.
For example, if you had 100 AU (onces of gold) and wanted to report it
in dollars, but at a price of $997 per ounce, you could now easily say:
ledger bal -X '$,AU=$997'
These strings are now collected automagically in the file po/ledger.pot.
If you'd like to produce a translation, just run this command after
building Ledger:
msginit -l LOCALE -o LANG.po -i po/ledger.pot
Where LOCALE is a string like de or en_GB, and LANG is a short
descriptive word for your language.
Then send me this .po file so I can commit it to the Ledger sources
(alternatively, you could maintain the file in a fork on GitHub), and
setup the build script to format and install your new message catalog
during a "make install".
The old implementation used an account formatter, and was very
specialized. The new is done as a transaction filter, and works along
with everything else, eliminating bugs special to the equity report.
Created a new function, session_t::reread_journal_files, which throws
away all previous state data and reads in the same files again. This is
needed to allow Emacs to communicate with Ledger via the REPL, so that
it tell Ledger when it has made changes to the user's data file.
