Re^5: Identifying a location with finer granularity than a line number (B::Concise)

currently B::Terse and B::Concise parse the source text a new rather than have the ability to work on an in place node structure

I'm pretty sure you are precisely wrong on that point.

The B::Concise man page shows how to call the compile() method which does not take Perl source code (despite what the name "compile" might imply) but only a list of subroutine names or CODE refs. So it seems pretty clear that the module walks the opnode tree of your existing interpreter instance for Perl code that you have already compiled. Looking at the source code of B::Concise and B confirms this.

Ah, yes. Ok. So now how can I get a CODE ref from the call stack of a running Perl program? Independent of this particular problem, it's something I'd want to be able to do. I can't remember the details now but I recall needing a CODE ref (as opposed to a in "context") in conjunction with the module Scope::Upper	[reply]

For the record, recent versions — 0.08 and later — of Devel::Callsite gives the OP address that you are stopped at or of a caller in the call stack. (The address of the OP is a child of the COP instruction, but this isn't an important distinction.)	[reply]
