## Install
```
$ npm install ansi-regex
```
## Usage
```js
const ansiRegex = require('ansi-regex');
ansiRegex().test('\u001B[4mcake\u001B[0m');
//=> true
ansiRegex().test('cake');
//=> false
'\u001B[4mcake\u001B[0m'.match(ansiRegex());
//=> ['\u001B[4m', '\u001B[0m']
'\u001B[4mcake\u001B[0m'.match(ansiRegex({onlyFirst: true}));
//=> ['\u001B[4m']
'\u001B]8;;https://github.com\u0007click\u001B]8;;\u0007'.match(ansiRegex());
//=> ['\u001B]8;;https://github.com\u0007', '\u001B]8;;\u0007']
```
## API
### ansiRegex([options])
Returns a regex for matching ANSI escape codes.
#### options
##### onlyFirst
Type: `boolean`<br>
Default: `false` *(Matches any ANSI escape codes in a string)*
Match only the first ANSI escape.
## FAQ
### Why do you test for codes not in the ECMA 48 standard?
Some of the codes we run as a test are codes that we acquired finding various lists of non-standard or manufacturer specific codes. We test for both standard and non-standard codes, as most of them follow the same or similar format and can be safely matched in strings without the risk of removing actual string content. There are a few non-standard control codes that do not follow the traditional format (i.e. they end in numbers) thus forcing us to exclude them from the test because we cannot reliably match them.
On the historical side, those ECMA standards were established in the early 90's whereas the VT100, for example, was designed in the mid/late 70's. At that point in time, control codes were still pretty ungoverned and engineers used them for a multitude of things, namely to activate hardware ports that may have been proprietary. Somewhere else you see a similar 'anarchy' of codes is in the x86 architecture for processors; there are a ton of "interrupts" that can mean different things on certain brands of processors, most of which have been phased out.

# SYNOPSIS
A sync prompt for node. very simple. no C++ bindings and no bash scripts.
Works on Linux, OS X and Windows.
# BASIC MODE
```js
var prompt = require('prompt-sync')();
//
// get input from the user.
//
var n = prompt('How many more times? ');
```
# WITH HISTORY
History is an optional extra, to use simply install the history plugin.
```sh
npm install --save prompt-sync-history
```
```js
var prompt = require('prompt-sync')({
history: require('prompt-sync-history')() //open history file
});
//get some user input
var input = prompt()
prompt.history.save() //save history back to file
```
See the [prompt-sync-history](http://npm.im/prompt-sync-history) module
for options, or fork it for customized behaviour.
# API
## `require('prompt-sync')(config) => prompt`
Returns an instance of the `prompt` function.
Takes `config` option with the following possible properties
`sigint`: Default is `false`. A ^C may be pressed during the input process to abort the text entry. If sigint it `false`, prompt returns `null`. If sigint is `true` the ^C will be handled in the traditional way: as a SIGINT signal causing process to exit with code 130.
`eot`: Default is `false`. A ^D pressed as the first character of an input line causes prompt-sync to echo `exit` and exit the process with code 0.
`autocomplete`: A completer function that will be called when user enters TAB to allow for autocomplete. It takes a string as an argument an returns an array of strings that are possible matches for completion. An empty array is returned if there are no matches.
`history`: Takes an object that supplies a "history interface", see [prompt-sync-history](http://npm.im/prompt-sync-history) for an example.
## `prompt(ask, value, opts)`
`ask` is the label of the prompt, `value` is the default value
in absence of a response.
The `opts` argument can also be in the first or second parameter position.
Opts can have the following properties
`echo`: Default is `'*'`. If set the password will be masked with the specified character. For hidden input, set echo to `''` (or use `prompt.hide`).
`autocomplete`: Overrides the instance `autocomplete` function to allow for custom
autocompletion of a particular prompt.
`value`: Same as the `value` parameter, the default value for the prompt. If `opts`
is in the third position, this property will *not* overwrite the `value` parameter.
`ask`: Sames as the `value` parameter. The prompt label. If `opts` is not in the first position, the `ask` parameter will *not* be overridden by this property.
## `prompt.hide(ask)`
Convenience method for creating a standard hidden password prompt,
this is the same as `prompt(ask, {echo: ''})`
# LINE EDITING
Line editing is enabled in the non-hidden mode. (use up/down arrows for history and backspace and left/right arrows for editing)
History is not set when using hidden mode.
# EXAMPLES
```js
//basic:
console.log(require('prompt-sync')()('tell me something about yourself: '))
var prompt = require('prompt-sync')({
history: require('prompt-sync-history')(),
autocomplete: complete(['hello1234', 'he', 'hello', 'hello12', 'hello123456']),
sigint: false
});
var value = 'frank';
var name = prompt('enter name: ', value);
console.log('enter echo * password');
var pw = prompt({echo: '*'});
var pwb = prompt('enter hidden password (or don\'t): ', {echo: '', value: '*pwb default*'})
var pwc = prompt.hide('enter another hidden password: ')
var autocompleteTest = prompt('custom autocomplete: ', {
autocomplete: complete(['bye1234', 'by', 'bye12', 'bye123456'])
});
prompt.history.save();
console.log('\nName: %s\nPassword *: %s\nHidden password: %s\nAnother Hidden password: %s', name, pw, pwb, pwc);
console.log('autocomplete2: ', autocompleteTest);
function complete(commands) {
return function (str) {
var i;
var ret = [];
for (i=0; i< commands.length; i++) {
if (commands[i].indexOf(str) == 0)
ret.push(commands[i]);
}
return ret;
};
};
```

If done correctly; the divisor should be set to the largest prime factor and the num should also be the same as the divisor -- dividing by the same number gives you 1 which will boot you out of the loop. Then we display the divisor in the console as the answer. */
