} This is cool. But what options are necessary in order to make this
} work? The commands above produce this output for me:
}
} Some
} text
} [particular
} text]
} Another
} text
unsetopt shwordsplit
or place each of the $txt[...] in double quotes:
print -l "$txt[1,$txt[(i)\[]-2]" "$txt[(r)\[,(R)\]]" "$txt[$txt[(I)\]]+2,-1]"
You'll find that many examples posted to zsh-users assume that arrays are
superior to strings-automatically-split-at-spaces, and therefore assume
that you're using the default zsh setting of no_shwordsplit.
