REPL

Runs M42PL as a REPL (interactive command interpreter).

m42pl repl

General usage

• M42PL' REPL read multiples lines at once; to execute the pipeline you typed, hit Escape then Enter
• When a pipeline is running, type Ctrl+c to stop it
• You can use the arrow keys to move in history and in the pipeline source
• The REPL automatically adds an output command to your pipeline if you didn't added a similar command; use another dispatcher (-d <dipatcher name>) such as local to avoid this behaviour

Arguments

Tip
Run m42pl repl -h or m42pl repl --help to get help
