B::Hooks::Parser - Interface to perls parser variables
This module provides an API for parts of the perl parser. It can be used
to modify code while it's being parsed.
Does some initialization work. This must be called before any other
functions of this module if you intend to use "set_linestr". Returns an
id that can be used to disable the magic using "teardown".
Disables magic registed using "setup".
Returns the line the parser is currently working on, or undef if perl
isn't parsing anything right now.
Returns the position within the current line to which perl has already
parsed the input, or -1 if nothing is being parsed currently.
Sets the line the perl parser is currently working on to $string.
Note that perl won't notice any changes in the line string after the
position returned by "get_linestr_offset".
Throws an exception when nothing is being compiled.
Convenience function to insert a piece of perl code into the current
line string (as returned by "get_linestr") at the current offset (as
returned by "get_linestr_offset").
The following functions work just like their equivalent in the perl api.
hook_op_check_id hook_parser_setup (void)
void hook_parser_teardown (hook_op_check_id id)
const char *hook_parser_get_linestr (pTHX)
IV hook_parser_get_linestr_offset (pTHX)
hook_parser_set_linestr (pTHX_ const char *new_value)
