Several places mention perldb command `w' (window). Is that command missing from more recent versions of perldb?
Loading DB routines from perl5db.pl version 1.19
DB<1> w Adding a watch-expression requires an expression
Yes, there is `l' and `-' -- however, these show lines only _after_ or _before_ the current line. `w' in the reference webpage results in a window with lines _before_ and _after_ the current line, which is ideal for establishing context.
How can I do this with my perldb?
Unfortunately perl 5.8 has mucked around with letters and redefined a bunch of them. Using 'h' will tell you what are the new commands:
DB<1> h List/search source lines: Control script execution: l [ln|sub] List source code T Stack trace - or . List previous/current line s [expr] Single step [in expr] v [line] View around line n [expr] Next, steps over subs
so you are after 'v' in 5.8+, what used to be 'w' in 5.6
I'll update the online docs.
