Not working on cygwin

[mijoharas]

I've started needing to use a cygwin environment for work so have tried copying my settings (including opp.zsh) over.
When trying to perform ciw I get:

opp-generic-w:5: command not found: opp-skip-alnum-backward
opp-generic-w:6: command not found: opp-skip-alnum-forward

Hi, @mijoharas . Thank you very much for your report.

opp-skip-alnum-backward and opp-skip-alnum-forward are defined by using cat command.

Does below snippet work on cygwin environment?

# copied from opp.zsh.
def-opp-skip () {
  eval "$(cat <<EOT
    $1 () { while [[ \${BUFFER[((CURSOR$3))]-} == $4 ]] do ((CURSOR$2)) done }
    zle -N $1
EOT
  )"
}
def-opp-skip opp-skip-alnum-backward   -- -0 "[[:alnum:]_]"
echo $functions[opp-skip-alnum-backward]

This should output below:

        while [[ ${BUFFER[((CURSOR-0))]-} = [[:alnum:]_] ]]
        do
                ((CURSOR--))
        done
