fix: compare version

[karrybit]

fixed bug to compare version.

Minimum reproduction code is below.

#!/bin/bash

function compare_old() {
  input_version=$1
  if [[ "$input_version" < "v0.64.0" ]]; then
    echo "Error: runn version $input_version is not supported. Please use v0.64.0 or higher."
    return
  fi

  echo "Success"
}

function compare_new() {
  input_version=$(echo "$1" | sed 's/^v//')
  compatible_version=$(echo "v0.64.0" | sed 's/^v//')

  IFS='.' read -r -a splitted_input_version <<< "$input_version"
  IFS='.' read -r -a splitted_compatible_version <<< "$compatible_version"

  for i in {0..2}; do
    if [[ ! ${splitted_input_version[i]} =~ ^[0-9]+$ ]]; then
      echo "Error: $input_version is invalid version."
      return
    fi

    if ((10#${splitted_input_version[i]} < 10#${splitted_compatible_version[i]})); then
      echo "Error: runn version $input_version is not supported. Please use $compatible_version or higher."
      return
    fi
  done
  echo "Success"
}

compare_old v0.113.2
compare_new v0.113.2

❯ ./compare_version.sh
Error: runn version v0.113.2 is not supported. Please use v0.64.0 or higher.
