ReplOptions

Stop evaluating the current piece of code when SIGINT is received, i.e. Ctrl+C is pressed. This cannot be used together with a custom eval function.

An optional function used for custom Tab auto completion.

The function to be used when evaluating each given line of input. Default: an async wrapper for the JavaScript eval() function. An eval function can error with repl.Recoverable to indicate the input was incomplete and prompt for additional lines.

If true, specifies that the default writer will not output the return value of a command if it evaluates to undefined.

The Readable stream from which REPL input will be read.

The Writable stream to which REPL output will be written.

Defines if the repl prints output previews or not.

The input prompt to display.

A flag that specifies whether the default evaluator executes all JavaScript commands in strict mode or default (sloppy) mode. Accepted values are:

If true, specifies that the output should be treated as a TTY terminal, and have ANSI/VT100 escape codes written to it. Default: checking the value of the isTTY property on the output stream upon instantiation.

If true, specifies that the default writer function should include ANSI color styling to REPL output. If a custom writer function is provided then this has no effect.

If true, specifies that the default evaluation function will use the JavaScript global as the context as opposed to creating a new separate context for the REPL instance. The node CLI REPL sets this value to true.

The function to invoke to format the output of each command before writing to output.
