sciteco/goto.cpp, branch v2.5.2

autoconf preparation: move everything into src/ subdir

2012-12-04T21:07:08+00:00

some minor simplifications of the goto code

2012-11-20T05:07:34+00:00

goto table cleanup

2012-11-20T05:07:33+00:00

make goto tables local to macro invocation: they are declared on the C++ callstack since macro invocations result in nested macro_execute() calls

2012-11-20T05:07:33+00:00

otherwise a macro could set labels with program counters which are invalid in other macros/the command line

Make sure undo tokens and RB-tree entries are destroyed properly

2012-11-16T22:14:00+00:00

 * when a pointer to an abstract base class is "deleted", it must have a virtual destructor so the destructor of derived classes is executed
 * fixes for instance, deletion of save point files when the command line is terminated (undo stack is discarded)
 * simplified some undotoken code

support different kinds of runtime errors (using C++ exceptions)

2012-11-16T17:57:34+00:00

 * also added some additional range checks (e.g. X command)

distinguish between GOTO, LOOP and CONDITIONAL parse-only modes: fixes loop branching in conditionals

2012-11-12T20:44:46+00:00

e.g. <0"=1;'...do something...> now works as expected

added O...$ GOTO command

2012-11-11T06:49:06+00:00

dump goto table only in DEBUG mode

2012-11-11T00:59:48+00:00

RBTree class (wrapper around BSD macros) - use for Goto table

2012-11-11T00:57:20+00:00

 * the other classes (Table, StringTable, StringTableUndo) do not yet work
