<p>The <code>repl</code> module provides a Read-Eval-Print-Loop (REPL) implementation that
is available both as a standalone program or includible in other applications.
It can be accessed using:</p>
<pre><code class="language-js">const repl = require('repl');
</code></pre>
<h2>Design and Features<span><a class="mark" href="#repl_design_and_features" id="repl_design_and_features">#</a></span></h2>
<p>The <code>repl</code> module exports the <a href="#repl_class_replserver"><code>repl.REPLServer</code></a> class. While running,
instances of <a href="#repl_class_replserver"><code>repl.REPLServer</code></a> will accept individual lines of user input,
evaluate those according to a user-defined evaluation function, then output the
result. Input and output may be from <code>stdin</code> and <code>stdout</code>, respectively, or may
be connected to any Node.js <a href="https://nodejs.org/api/stream.html">stream</a>.</p>
<p>Instances of <a href="#repl_class_replserver"><code>repl.REPLServer</code></a> support automatic completion of inputs,
simplistic Emacs-style line editing, multi-line inputs, ANSI-styled output,
saving and restoring current REPL session state, error recovery, and
customizable evaluation functions.</p>
<h3>Commands and Special Keys<span><a class="mark" href="#repl_commands_and_special_keys" id="repl_commands_and_special_keys">#</a></span></h3>
<p>The following special commands are supported by all REPL instances:</p>
<ul>
<li><code>.break</code> - When in the process of inputting a multi-line expression, entering
the <code>.break</code> command (or pressing the <code><ctrl>-C</code> key combination) will abort
further input or processing of that expression.</li>
<li><code>.clear</code> - Resets the REPL <code>context</code> to an empty object and clears any
multi-line expression currently being input.</li>
<li><code>.exit</code> - Close the I/O stream, causing the REPL to exit.</li>
<li><code>.help</code> - Show this list of special commands.</li>
<li><code>.save</code> - Save the current REPL session to a file:
<code>> .save ./file/to/save.js</code></li>
<li><code>.load</code> - Load a file into the current REPL session.
<code>> .load ./file/to/load.js</code></li>
<li><code>.editor</code> - Enter editor mode (<code><ctrl>-D</code> to finish, <code><ctrl>-C</code> to cancel).</li>
</ul>
<pre><code class="language-console">> .editor
// Entering editor mode (^D to finish, ^C to cancel)
function welcome(name) {
return `Hello ${name}!`;
}
welcome('Node.js User');
// ^D
'Hello Node.js User!'
>
</code></pre>
<p>The following key combinations in the REPL have these special effects:</p>
<ul>
<li><code><ctrl>-C</code> - When pressed once, has the same effect as the <code>.break</code> command.
When pressed twice on a blank line, has the same effect as the <code>.exit</code>
command.</li>
<li><code><ctrl>-D</code> - Has the same effect as the <code>.exit</code> command.</li>
<li><code><tab></code> - When pressed on a blank line, displays global and local (scope)
variables. When pressed while entering other input, displays relevant
autocompletion options.</li>
</ul>
<h3>Default Evaluation<span><a class="mark" href="#repl_default_evaluation" id="repl_default_evaluation">#</a></span></h3>
<p>By default, all instances of <a href="#repl_class_replserver"><code>repl.REPLServer</code></a> use an evaluation function
that evaluates JavaScript expressions and provides access to Node.js' built-in
modules. This default behavior can be overridden by passing in an alternative
evaluation function when the <a href="#repl_class_replserver"><code>repl.REPLServer</code></a> instance is created.</p>
<h4>JavaScript Expressions<span><a class="mark" href="#repl_javascript_expressions" id="repl_javascript_expressions">#</a></span></h4>
<p>The default evaluator supports direct evaluation of JavaScript expressions:</p>
<pre><code class="language-console">> 1 + 1
2
> const m = 2
undefined
> m + 1
3
</code></pre>
<p>Unless otherwise scoped within blocks or functions, variables declared
either implicitly or using the <code>const</code>, <code>let</code>, or <code>var</code> keywords
are declared at the global scope.</p>
<h4>Global and Local Scope<span><a class="mark" href="#repl_global_and_local_scope" id="repl_global_and_local_scope">#</a></span></h4>
<p>The default evaluator provides access to any variables that exist in the global
scope. It is possible to expose a variable to the REPL explicitly by assigning
it to the <code>context</code> object associated with each <code>REPLServer</code>:</p>
<pre><code class="language-js">const repl = require('repl');
const msg = 'message';
repl.start('> ').context.m = msg;
</code></pre>
<p>Properties in the <code>context</code> object appear as local within the REPL:</p>
<pre><code class="language-console">$ node repl_test.js
> m
'message'
</code></pre>
<p>Context properties are not read-only by default. To specify read-only globals,
context properties must be defined using <code>Object.defineProperty()</code>:</p>
<pre><code class="language-js">const repl = require('repl');
const msg = 'message';
const r = repl.start('> ');
Object.defineProperty(r.context, 'm', {
configurable: false,
enumerable: true,
value: msg
});
</code></pre>
<h4>Accessing Core Node.js Modules<span><a class="mark" href="#repl_accessing_core_node_js_modules" id="repl_accessing_core_node_js_modules">#</a></span></h4>
<p>The default evaluator will automatically load Node.js core modules into the
REPL environment when used. For instance, unless otherwise declared as a
global or scoped variable, the input <code>fs</code> will be evaluated on-demand as
<code>global.fs = require('fs')</code>.</p>
<pre><code class="language-console">> fs.createReadStream('./some/file');
</code></pre>
<h4>Global Uncaught Exceptions<span><a class="mark" href="#repl_global_uncaught_exceptions" id="repl_global_uncaught_exceptions">#</a></span></h4>

</div>
<p>The REPL uses the <a href="https://nodejs.org/api/domain.html"><code>domain</code></a> module to catch all uncaught exceptions for that
REPL session.</p>
<p>This use of the <a href="https://nodejs.org/api/domain.html"><code>domain</code></a> module in the REPL has these side effects:</p>
<ul>
<li>Uncaught exceptions only emit the <a href="https://nodejs.org/api/process.html#process_event_uncaughtexception"><code>'uncaughtException'</code></a> event if the
<code>repl</code> is used as standalone program. If the <code>repl</code> is included anywhere in
another application, adding a listener for this event will throw an
<a href="https://nodejs.org/api/errors.html#errors_err_invalid_repl_input"><code>ERR_INVALID_REPL_INPUT</code></a> exception.</li>
<li>Trying to use <a href="https://nodejs.org/api/process.html#process_process_setuncaughtexceptioncapturecallback_fn"><code>process.setUncaughtExceptionCaptureCallback()</code></a> throws
an <a href="https://nodejs.org/api/errors.html#errors_err_domain_cannot_set_uncaught_exception_capture"><code>ERR_DOMAIN_CANNOT_SET_UNCAUGHT_EXCEPTION_CAPTURE</code></a> error.</li>
</ul>
<p>As standalone program:</p>
<pre><code class="language-js">process.on('uncaughtException', () => console.log('Uncaught'));
throw new Error('foobar');
// Uncaught
</code></pre>
<p>When used in another application:</p>
<pre><code class="language-js">process.on('uncaughtException', () => console.log('Uncaught'));
// TypeError [ERR_INVALID_REPL_INPUT]: Listeners for `uncaughtException`
// cannot be used in the REPL
throw new Error('foobar');
// Thrown:
// Error: foobar
</code></pre>
<h4>Assignment of the <code>_</code> (underscore) variable<span><a class="mark" href="#repl_assignment_of_the_underscore_variable" id="repl_assignment_of_the_underscore_variable">#</a></span></h4>

<p>The default evaluator will, by default, assign the result of the most recently

Explicitly setting <code>_</code> to a value will disable this behavior.</p>
<pre><code class="language-console">> [ 'a', 'b', 'c' ]

<h3>Custom Evaluation Functions<span><a class="mark" href="#repl_custom_evaluation_functions" id="repl_custom_evaluation_functions">#</a></span></h3>
<p>When a new <a href="#repl_class_replserver"><code>repl.REPLServer</code></a> is created, a custom evaluation function may be
provided. This can be used, for instance, to implement fully customized REPL
applications.</p>
<p>The following illustrates a hypothetical example of a REPL that performs
translation of text from one language to another:</p>
<pre><code class="language-js">const repl = require('repl');
const { Translator } = require('translator');
const myTranslator = new Translator('en', 'fr');
function myEval(cmd, context, filename, callback) {
callback(null, myTranslator.translate(cmd));
}
repl.start({ prompt: '> ', eval: myEval });
</code></pre>
<h4>Recoverable Errors<span><a class="mark" href="#repl_recoverable_errors" id="repl_recoverable_errors">#</a></span></h4>
<p>As a user is typing input into the REPL prompt, pressing the <code><enter></code> key will
send the current line of input to the <code>eval</code> function. In order to support
multi-line input, the eval function can return an instance of <code>repl.Recoverable</code>
to the provided callback function:</p>
<pre><code class="language-js">function myEval(cmd, context, filename, callback) {
let result;
try {
result = vm.runInThisContext(cmd);
} catch (e) {
if (isRecoverableError(e)) {
return callback(new repl.Recoverable(e));
}
}
callback(null, result);
}
function isRecoverableError(error) {
if (error.name === 'SyntaxError') {
return /^(Unexpected end of input|Unexpected token)/.test(error.message);
}
return false;
}
</code></pre>
<h3>Customizing REPL Output<span><a class="mark" href="#repl_customizing_repl_output" id="repl_customizing_repl_output">#</a></span></h3>
<p>By default, <a href="#repl_class_replserver"><code>repl.REPLServer</code></a> instances format output using the
<a href="https://nodejs.org/api/util.html#util_util_inspect_object_options"><code>util.inspect()</code></a> method before writing the output to the provided <code>Writable</code>
stream (<code>process.stdout</code> by default). The <code>showProxy</code> inspection option is set
to true by default and the <code>colors</code> option is set to true depending on the
REPL's <code>useColors</code> option.</p>
<p>The <code>useColors</code> boolean option can be specified at construction to instruct the
default writer to use ANSI style codes to colorize the output from the
<code>util.inspect()</code> method.</p>
<p>If the REPL is run as standalone program, it is also possible to change the
REPL's <a href="https://nodejs.org/api/util.html#util_util_inspect_object_options">inspection defaults</a> from inside the REPL by using the
<code>inspect.replDefaults</code> property which mirrors the <code>defaultOptions</code> from
<a href="https://nodejs.org/api/util.html#util_util_inspect_object_options"><code>util.inspect()</code></a>.</p>
<pre><code class="language-console">> util.inspect.replDefaults.compact = false;
false
> [1]
[
1
]
>
</code></pre>
<p>To fully customize the output of a <a href="#repl_class_replserver"><code>repl.REPLServer</code></a> instance pass in a new
function for the <code>writer</code> option on construction. The following example, for
instance, simply converts any input text to upper case:</p>
<pre><code class="language-js">const repl = require('repl');
const r = repl.start({ prompt: '> ', eval: myEval, writer: myWriter });
function myEval(cmd, context, filename, callback) {
callback(null, cmd);
}
function myWriter(output) {
return output.toUpperCase();
}
</code></pre>

</div>
<ul>
<li>Extends: <a href="https://nodejs.org/api/readline.html#readline_class_interface" class="type"><readline.Interface></a></li>
</ul>
<p>Instances of <code>repl.REPLServer</code> are created using the <code>repl.start()</code> method and

<h3>Event: 'exit'<span><a class="mark" href="#repl_event_exit" id="repl_event_exit">#</a></span></h3>
<div class="api_metadata">
<span>Added in: v0.7.7</span>
</div>
<p>The <code>'exit'</code> event is emitted when the REPL is exited either by receiving the
<code>.exit</code> command as input, the user pressing <code><ctrl>-C</code> twice to signal <code>SIGINT</code>,
or by pressing <code><ctrl>-D</code> to signal <code>'end'</code> on the input stream. The listener
callback is invoked without any arguments.</p>
<pre><code class="language-js">replServer.on('exit', () => {
console.log('Received "exit" event from repl!');
process.exit();
});
</code></pre>
<h3>Event: 'reset'<span><a class="mark" href="#repl_event_reset" id="repl_event_reset">#</a></span></h3>
<div class="api_metadata">
<span>Added in: v0.11.0</span>
</div>
<p>The <code>'reset'</code> event is emitted when the REPL's context is reset. This occurs
whenever the <code>.clear</code> command is received as input <em>unless</em> the REPL is using
the default evaluator and the <code>repl.REPLServer</code> instance was created with the
<code>useGlobal</code> option set to <code>true</code>. The listener callback will be called with a
reference to the <code>context</code> object as the only argument.</p>
<p>This can be used primarily to re-initialize REPL context to some pre-defined
state:</p>
<pre><code class="language-js">const repl = require('repl');
function initializeContext(context) {
context.m = 'test';
}
const r = repl.start({ prompt: '> ' });
initializeContext(r.context);
r.on('reset', initializeContext);
</code></pre>
<p>When this code is executed, the global <code>'m'</code> variable can be modified but then
reset to its initial value using the <code>.clear</code> command:</p>
<pre><code class="language-console">$ ./node example.js
> m
'test'
> m = 1
1
> m
1
> .clear
Clearing context...
> m
'test'

</ul>
<p>The <code>replServer.defineCommand()</code> method is used to add new <code>.</code>-prefixed commands
to the REPL instance. Such commands are invoked by typing a <code>.</code> followed by the
<code>keyword</code>. The <code>cmd</code> is either a <code>Function</code> or an <code>Object</code> with the following
properties:</p>
<ul>
<li><code>help</code> <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Data_structures#String_type" class="type"><string></a> Help text to be displayed when <code>.help</code> is entered (Optional).</li>
<li><code>action</code> <a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Function" class="type"><Function></a> The function to execute, optionally accepting a single
string argument.</li>
</ul>
<p>The following example shows two new commands added to the REPL instance:</p>

const replServer = repl.start({ prompt: '> ' });
replServer.defineCommand('sayhello', {

console.log(`Hello, ${name}!`);
this.displayPrompt();
}
});
replServer.defineCommand('saybye', function saybye() {

<h3>Environment Variable Options<span><a class="mark" href="#repl_environment_variable_options" id="repl_environment_variable_options">#</a></span></h3>
<p>Various behaviors of the Node.js REPL can be customized using the following
environment variables:</p>
<ul>
<li><code>NODE_REPL_HISTORY</code> - When a valid path is given, persistent REPL history
will be saved to the specified file rather than <code>.node_repl_history</code> in the
user's home directory. Setting this value to <code>''</code> (an empty string) will
disable persistent REPL history. Whitespace will be trimmed from the value.
On Windows platforms environment variables with empty values are invalid so
set this variable to one or more spaces to disable persistent REPL history.</li>
<li><code>NODE_REPL_HISTORY_SIZE</code> - Controls how many lines of history will be
persisted if history is available. Must be a positive number.
<strong>Default:</strong> <code>1000</code>.</li>
<li><code>NODE_REPL_MODE</code> - May be either <code>'sloppy'</code> or <code>'strict'</code>. <strong>Default:</strong>
<code>'sloppy'</code>, which will allow non-strict mode code to be run.</li>

<h3>Persistent History<span><a class="mark" href="#repl_persistent_history" id="repl_persistent_history">#</a></span></h3>
<p>By default, the Node.js REPL will persist history between <code>node</code> REPL sessions
by saving inputs to a <code>.node_repl_history</code> file located in the user's home
directory. This can be disabled by setting the environment variable
<code>NODE_REPL_HISTORY=''</code>.</p>
<h3>Using the Node.js REPL with advanced line-editors<span><a class="mark" href="#repl_using_the_node_js_repl_with_advanced_line_editors" id="repl_using_the_node_js_repl_with_advanced_line_editors">#</a></span></h3>
<p>For advanced line-editors, start Node.js with the environment variable
<code>NODE_NO_READLINE=1</code>. This will start the main and debugger REPL in canonical
terminal settings, which will allow use with <code>rlwrap</code>.</p>
<p>For example, the following can be added to a <code>.bashrc</code> file:</p>
<pre><code class="language-text">alias node="env NODE_NO_READLINE=1 rlwrap node"
</code></pre>
<h3>Starting multiple REPL instances against a single running instance<span><a class="mark" href="#repl_starting_multiple_repl_instances_against_a_single_running_instance" id="repl_starting_multiple_repl_instances_against_a_single_running_instance">#</a></span></h3>
<p>It is possible to create and run multiple REPL instances against a single
running instance of Node.js that share a single <code>global</code> object but have
separate I/O interfaces.</p>
<p>The following example, for instance, provides separate REPLs on <code>stdin</code>, a Unix
socket, and a TCP socket:</p>
<pre><code class="language-js">const net = require('net');
const repl = require('repl');
let connections = 0;
repl.start({
prompt: 'Node.js via stdin> ',
input: process.stdin,
output: process.stdout
});
net.createServer((socket) => {
connections += 1;
repl.start({
prompt: 'Node.js via Unix socket> ',
input: socket,
output: socket
}).on('exit', () => {
socket.end();
});
}).listen('/tmp/node-repl-sock');
net.createServer((socket) => {
connections += 1;
repl.start({
prompt: 'Node.js via TCP socket> ',
input: socket,
output: socket
}).on('exit', () => {
socket.end();
});
}).listen(5001);
</code></pre>
<p>Running this application from the command line will start a REPL on stdin.
Other REPL clients may connect through the Unix socket or TCP socket. <code>telnet</code>,
for instance, is useful for connecting to TCP sockets, while <code>socat</code> can be used
to connect to both Unix and TCP sockets.</p>
<p>By starting a REPL from a Unix socket-based server instead of stdin, it is
possible to connect to a long-running Node.js process without restarting it.</p>
<p>For an example of running a "full-featured" (<code>terminal</code>) REPL over
a <code>net.Server</code> and <code>net.Socket</code> instance, see:
<a href="https://gist.github.com/TooTallNate/2209310">https://gist.github.com/TooTallNate/2209310</a>.</p>
<p>For an example of running a REPL instance over <a href="https://curl.haxx.se/docs/manpage.html"></a><a href="https://curl.haxx.se/docs/manpage.html"><code>curl(1)</code></a>, see:
