Hi Frank,

Yeah. I was a little quick about this. This only prints the number of
key-value pairs in the associative array. What we're actually looking
for is this:
% print ${#${(kv)color}}
In any case, `4' is too low a value. what does this print?
% printf '%s = '\''%s'\''\n' ${(kv)color} | sort
Not sure if this does what it was inteded to.
$ printf '%s = '\''%s'\''\n' ${(kv)color} | sort
= ''''''
' ${(kv)color} | sortnone = ''
When I just do the following I get
$ print ${(kv)color}
none
But I think I figured what you wanted.
Maybe this?
printf '%s = %s\n' ${(kv)color[*]} | sort
Anyway. I tried to to do some kind of single step printf debugging after
your printf hints and added the files as an attachement. I hope it might
be usefull to you, I just see there that the mapping at some point
fails, and bg-blue seems to be associated with fg-red. "bg-blue =
fg-red". Maybe some loop is missing a value and leads to an "uneven
association".
What I did:
I added some printfs to the colors function.
called
$ unset -f colors
$ autoload -U colors
$ colors
and grabbed the ouput.
I fear the line numbers are rubbish but you can see the place in the
colors file.
Thanks, I'll take a look at it when I'm on the train.
Godspeed.
What exactly does ${(kv)color} access? Is kv a value?
Those flags are used to access the keys and values of an associative
array:
% foo=( bar baz beer booze zack zonk )
% print ${foo[zack]}
zonk
% print ${(k)foo}
zack bar beer
% print ${(v)foo}
zonk baz booze
% print ${(kv)foo}
zack zonk bar baz beer booze
Thanks for the insight. I get it.
The latter is used to initialise $colour (British) with the same values
as in $color (American).
You just got to love it when you have to solve those kind of problems in IT.
regards,
Benjamin.
