sciteco/undo.h, branch v2.5.2

autoconf preparation: move everything into src/ subdir

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

undo.push_var() and undo.push_str() return references so calls can be used as l-values (common use case)

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

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

DEBUG support for printing state change undo tokens

2012-11-11T05:31:03+00:00

set UndoToken position only when it is required (undo enabled)

2012-11-08T17:17:19+00:00

support line termination ($$) as immediate editing command + some fixes

2012-11-08T01:21:36+00:00

 * separate function for immediate editing command processing
 * undo.clear() to remove and free all undo tokens without executing them
 * goto_table_clear() to remove and free all goto table entries

added support for labels, including the goto label table

2012-11-08T00:20:37+00:00

 * uses BSD tree macros, might later be abstracted to a C++ table class

undo stack enable/disable, parse-only mode, colon modifiers evaluation
