From 78e6770c4c276db3647952f21a6bf3ea465edb88 Mon Sep 17 00:00:00 2001 From: John Wiegley Date: Wed, 4 Nov 2009 20:40:07 -0500 Subject: 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) --- src/xact.cc | 8 ++++++-- 1 file changed, 6 insertions(+), 2 deletions(-) (limited to 'src/xact.cc') diff --git a/src/xact.cc b/src/xact.cc index 3291c5be..473837b6 100644 --- a/src/xact.cc +++ b/src/xact.cc @@ -422,8 +422,12 @@ namespace { } } -expr_t::ptr_op_t xact_t::lookup(const string& name) +expr_t::ptr_op_t xact_t::lookup(const symbol_t::kind_t kind, + const string& name) { + if (kind != symbol_t::FUNCTION) + return item_t::lookup(kind, name); + switch (name[0]) { case 'c': if (name == "code") @@ -448,7 +452,7 @@ expr_t::ptr_op_t xact_t::lookup(const string& name) break; } - return item_t::lookup(name); + return item_t::lookup(kind, name); } bool xact_t::valid() const -- cgit v1.2.3
