Hello Bart,

Thanks a lot for responding. I find your comments very informative and
a treasure trove for me.

gmail is adding application/octet-stream. I will send both the .zsh
file and a .txt file.

On a slightly different note, I do not feel comfortable using the ((
.. )) construct as it does not show up properly in the xtrace/verbose
log. This is how it shows up.

+limit-completion:21> (( compstate[list_lines] > 60         ||
compstate[list_lines]+BUFFERLINES+2 > LINES ))

whereas the [[ .. ]] construct shows up like this:

+limit-completion:23> [[ 7 -gt 60 ||+limit-completion:23> expr 7 + 2 + 2
+limit-completion:23> [[ 7 -gt 60 || 11 -gt 47 ]]

I think the [[ .. ]] is more comprehensible.

Fixed it. I picked the above localoptions from your earlier code on
_debug_widget.

I could not figure out why the below lines do not work. They return a blank.

   echo "4: $(expr ${compstate[list_lines]})"
   echo "5: $(expr $compstate[list_lines])"
   echo "6: $(expr $compstate[list_lines] + $BUFFERLINES)"
   echo "7: $(expr $compstate[list_lines] + $BUFFERLINES + 2)"

They are in lines 42 .. 45 of the attached script.

The debugging output from the lines 35 .. 57 of the attached file is:

+limit-completion:7> echo 'started limit-completion'
started limit-completion
+limit-completion:8> echo 'compstate[list_lines]: 8'
compstate[list_lines]: 8
+limit-completion:9> echo 'INCR_MAX_MATCHES: 60'
INCR_MAX_MATCHES: 60
+limit-completion:10> echo 'BUFFERLINES: 2'

+limit-completion:11> echo 'list_lines: 8'
list_lines: 8
+limit-completion:12> expr 8 + 2 + 2

+limit-completion:23> [[ 8 -gt 60 ||+limit-completion:23> expr 8 + 2 + 2
+limit-completion:23> [[ 8 -gt 60 || 12 -gt 47 ]]

Whereas, when I tried the associative array workings from the command
line, it worked fine:
- (0:c:/tmp)  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -
typeset -A NAME
- (0:c:/tmp)  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -
NAME=(test1 1 test2 2 test3 3 test4 4)
- (0:i:/tmp)  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -
echo $NAME
1 2 3 4
- (0:i:/tmp)  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -
echo $NAME[test1]
1
- (0:i:/tmp)  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -
expr $NAME[test1] + 2
3
- (0:i:/tmp)  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -
echo $(expr $NAME[test1] + 2)
3
- (0:i:/tmp)  -  -  -  -  -  -  -  -  -  -  -  -  -  -  -
echo "$(expr $NAME[test1] + 2)"
3

Any thoughts, please?

Thanks
Joe
