Tried to run it, complained about needing gawk-cmd

Ran brew install gawk

Then ran kanban, got following error:

conditional binary operator expected
kanban: line 222: syntax error near "maximum_todo[$status]"' kanban: line 222: [[ -v "maximum_todo[$status]" ]] && maxlines=${maximum_todo[$status]}'

Code there looks like:

maxlines=0
[[ -v "maximum_todo[$status]" ]] && [[ maxlines=${maximum_todo[$status]} ]]
[[ ${maximum_todo[$status]} > -1 ]] && [[ $nlines > ${maximum_todo[$status]} ]] && label$
echo -e ".$(strtoline "$label" "~")~~.\n| $label |_______\n|" > $TMP.col.$i
