Subject: Re: [BUG] Anonymous functions cause funcfiletrace to produce function-relative line numbers
Date: Wed, 20 Dec 2017 17:39:41 +0000	[thread overview]
Message-ID: <20171220173941.141333d3@pwslap01u.europe.root.pri> (raw)
In-Reply-To: <20171218090155.58c65907@pwslap01u.europe.root.pri>

I think this might be going in the right direction.

We don't need PM_ANONYMOUS, and in fact we've tested before by using a
special name pointer, but I quite like it for future use anyway...

I tried it with the following...

#snip
# this is line 1

foo() {

bar() { () { (){ print -rC2 -- $functrace $funcfiletrace; } } }
}
foo
bar
#snip

and got

(anon):0     ./why.txt:5
bar:0        ./why.txt:5
./why.txt:8  ./why.txt:8
zsh:1        zsh:1

which looks an improvement.

Probably not much activity till the New Year now.
