Command Line Options

  • -C, --client
    Starts in REPL client mode. Connects to the REPL address specified by the --repl option. Uses 127.0.0.1:9999 if no address is specified.
  • -c <file name>, --config <file name>
    The config file to run. Uses jwno-config.janet in the same directory as jwno.exe by default.
  • -e <expressions>, --eval <expressions>
    Evaluates some Janet code through a REPL connection, then exit. Only shows the output from the REPL when there's an error. To see all REPL output, set --log-level to debug.
  • -x <command>, --execute <command>
    Executes a command through a REPL connection, then exit. The colon (:) in front of a command name can be omitted, but all arguments must be in correct Janet syntax. For example, in this command jwno.exe -x ":move-window :left", the first colon can be omitted, but the second colon is needed for Jwno to parse the keyword argument correctly.
  • -E, --export-all
    After processing the --eval option to evaluate Janet code, exports all symbols in the REPL environment. This option essentially "saves" the environment modified by the evaluated code, and makes it available to other REPL connections.
  • -h, --help
    Shows a help message.
  • --log-file <file name>
    Specifies a log file to write to. No log file will be generated if this option is omitted.
  • --log-level <level>
    The log level. Can be quiet, error, warning, info or debug. Default: quiet.
  • -m <path name>, --mod-path <path name>
    A custom path to load modules from. Can be specified multiple times. Uses the directory where the config file resides by default.
  • --no-console
    Supresses console output, when --log-level is not quiet.
  • -r <ip:port>, --repl <ip:port>
    Specifies the address the REPL should be listening on. The REPL will not be started if this option is omitted.
  • -v, --version
    Shows version info then exit.

All other command line arguments that do not begin with a hyphen - will be interpreted as config file names, but they can be overridden by the -c or --config option.
