annotate libinterp/parse-tree/oct-parse.in.yy @ 23705:4c597585ff52

move Vmax_recursion_depth and Vsilent_functions to tree_evaluator class * pt-eval.h, pt-eval.cc (tree_evaluator::m_max_recursion_depth, tree_evaluator::m_silent_functions): New variables. (tree_evaluator::max_recursion_depth, tree_evaluator::silent_functions): New functions. (Vmax_recursion_depth, Vsilent_functions): Delete. (Fsilent_functions): Access silent_functions through tree_evaluator. (Fmax_recursion_depth): Likewise, for max_recursion_depth. (tree_evaluator::statement_printing_enabled): No longer static. Change all uses. * ov-usr-fcn.cc (octave_user_script::call, octave_user_function::call): Access max_recursion_depth through tree_evaluator. * oct-parse.in.yy (source_file): Likewise.
