Scripts

Spinner v1

Feature-rich terminal spinner with process wrapper, colors, and live output. Documentation

Spinner v2 (العربية)

Arabic version of the spinner with Arabic keywords, variables, and UI. Documentation

Exit Code Standard

All scripts in this repository follow a consistent exit code convention:

Code	Meaning	Description
0	Success	Script completed normally
1	General error	Unexpected failure or runtime error
2	Usage error	Invalid flag or bad argument combination
3	Missing argument	A flag was provided but no value followed it
4	Invalid value	A value was provided but was wrong type or out of range
5	Permission denied	Insufficient permissions to perform the operation
6	File not found	A required file or resource does not exist

Usage in scripts:

dec args = args()

if args.arr_contains("-h")? {
  print_usage()
  exit(0)
}

if args.arr_contains("-f")? {
  dec target_index = args.arr_index_of("-f")?
  if !(args[target_index] == args.arr_last()?) {
    if target_index + 1 < args.len()? {
      dec path = args[target_index + 1]
      if !file_exists(path) {
        eprintln(format("error: file '{}' not found", path))
        exit(6)
      }
    } else {
      eprintln("error: '-f' requires a file path")
      exit(3)
    }
  } else {
    eprintln("error: missing file path after '-f'")
    exit(3)
  }
}

Checking in pipelines:

rl run script.rl -f config.txt
case $? in
  0) echo "success" ;;
  2) echo "bad usage" ;;
  3) echo "missing argument" ;;
  4) echo "invalid value" ;;
  5) echo "permission denied" ;;
  6) echo "file not found" ;;
  *) echo "unexpected error" ;;
