Hello

In code, I declare reply2 and reply3 as arrays via typeset -ga. I do
this from inside of a function. When the code returns to outer scope,
(t)reply2 and (t)reply3 show empty strings. The following lines start
at line 293 in lib/script_functions:

    typeset -ga reply2 reply3
    echo "T1 ${(t)reply} T2 ${(t)reply2} T3 ${(t)reply3}"
    reply=3D( "${existing[@]}" )
    reply2=3D( "${files[@]}" )
    reply3=3D( "${sections[@]}" )

This is inner scope. The outer scope (line 1148 in zsh-select-zekyll) does:

    filter_for_existing_zekylls "${zekylls[@]}"
    three_to_section_order "${#reply}" "${reply[@]}" "${reply2[@]}"
"${reply3[@]}"

    echo "t1 ${(t)reply} t2 ${(t)reply2} t3 ${(t)reply3}"
    local -a existing files sections
    existing=3D( "${reply[@]}" )
    files=3D( "${reply2[@]}" )
    sections=3D( "${reply3[@]}" )

    echo "existing count: ${#existing}, files count: ${#files},
sections count: ${#sections}"

t1-t3 show empty string. Assigning ${reply2[@]} to files=3D( ... ) cause
the variable files to contain one mysterious element =E2=80=93 it is empty,
probably.


To run the code first download zekyll, the investigation branch:
https://github.com/psprint/zekyll/tree/investig

it has to be unpacked to ~/.zekyll, final directory "zekyll", so full
path ~/.zekyll/zekyl. One can also use install script:

    wget https://github.com/psprint/zekyll/blob/master/install.sh
    sh ./install.sh

Next, one also needs a zkl repository available under
~/.zekyll/repos/{the-zkl-repo} or somewhere else (the path below after
-mp must match). It can be downloaded from:

    https://github.com/psprint/zkl

After that, simply run command:

zkview -mp "/Users/sgniazdowski/github/zkl.git" --zkl
aaaaabaacaadaaeaafaagaahaaiaajaakaalaamaanaaoaap

Errorneous output will be created:

Read: aaaaabaacaadaaeaafaagaahaaiaajaakaalaamaanaaoaap

Checking current zekyll for duplicates...
