a perldbg question about breaks

misterperl has asked for the wisdom of the Perl Monks concerning the following question:

I know I can set

dbg> b myclass::mymethod
[download]

anywhere. Which is very useful. And I can set

dbg> b 123
[download]

to break at line 123 in my current scope. But, can I set a break at a line in another class, like

dbg> b myclass::123
[download]

(I know THAT doesn't work) but is there a syntax to do that? TY

What I usually do in this case: `f myclass.pm b 123` [download] The `f` command takes a regular expression, so depending on how many classes you've already loaded, you might be able to abbreviate it to `f myc`. The debugger will tell you which file it selected so that you can redo the command with a refined regular expression to eliminate unexpected choices.	[reply] [d/l]

Don't know if there's a quicker way, but you can use the `f filename` debugger command to change the context to the `myclass.pm` file then set a breakpoint with a line number and it'll be relative to the current file. I actually did just this the other day so I'm interested if there's a faster way or alternate syntax as well. The cake is a lie. The cake is a lie. The cake is a lie.	[reply] [d/l] [select]

perldebug#`b [file]:[line] [condition]` ? NB: The condition is optional. Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply] [d/l]

OK you explicitly asked about the "package" not the "file". But that's not how it works because the same package can be present in different files. (think of main:: for instance) Assuming the normal case that the package scope is only in one single file... If this is only a one-time application, finding the correct file-path shouldn't be a problem. Otherwise one could write an alias which finds the filename for a provided package and sets the breakpoint. Compare also `%INC` which lists the filenames for used modules.

ALL replies are ++'s guys TY. I never knew about the f command... Bless you all (into the class of angels!)	[reply]
