Module regparse 

Port of regparse.c: the parser, which turns a pattern (a byte string) into the AST of node trees that regcomp compiles. It also holds the global warning hooks and the parse limits.

Functions

onig_get_ast_node_limit

Returns the per-pattern AST budget, in expression nodes (see onig_set_ast_node_limit).

onig_get_callout_name_by_name_id

Get the name of a registered callout by its name ID. Port of C’s onig_get_callout_name_by_name_id.

onig_get_parse_depth_limit

Returns the nesting limit, in parser units (see onig_set_parse_depth_limit).

onig_set_ast_node_limit

Sets the per-pattern AST budget: how many expression nodes one pattern may parse into, flat concatenation and alternation cells included. A pattern over the budget fails with ParseDepthLimitOver.

onig_set_callout_of_name

Register a user-defined named callout. Port of C’s onig_set_callout_of_name.

onig_set_capture_num_limit

onig_set_parse_depth_limit

Sets the nesting limit: how deeply a pattern may nest before it fails with ParseDepthLimitOver. Only nesting is limited; the number of expressions in a pattern is limited by onig_set_ast_node_limit.

onig_set_verb_warn_func

onig_set_warn_func
