bf24b93818 Fixes to the value expression parser and evaluator 2009-11-10 02:26:20 -05:00
John Wiegley
78e6770c4c Segregated symbols into 5 separate namespaces 
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)

7ca80112fc Change the value_t::POINTER type to value_t::SCOPE 
scope_t pointers are the only kind that are ever stored in value
objects, so there was no need to make it generic and use boost::any.

238bd7f8a5 Marked all strings needing internationalization 
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".

e919f53c99 Renamed O_COMMA to O_CONS, and changed semantics 
In the old scheme, nested values would simply flatten and concatenate,
so that '((1, 2), 3) = (1, 2, 3)'.  Now sublists are preserved, so that
sequences may be passed as arguments to functions.
