A sync prompt for node. very simple. no C++ bindings and no bash scripts.
var prompt = require('prompt-sync').prompt;
//
// write some text to the screen.
//
process.stdout.write('How many more times? ')
//
// get input from the user.
//
var n = prompt()prompt = require('prompt-sync') returns an object with three methods:
prompt.init(history-filename, max-history) // open history file.
prompt.save() // save history back to file
prompt.prompt(option) // do sync io from stdin
prompt.prompt() takes an optional argument object with the following properties
hidden: Default is false. This prevents echo-back during text entry
echo: Default is '*'. Echo character to be used. For no echo set this to ''
tabComplete: 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.
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.
prompt = require('prompt-sync');
prompt.init(); // start history. Use cursor up/down for history
console.log('Enter some text:');
var sometext = prompt.prompt({tabComplete: myCompleter});
console.log('Enter password:');
var password1 = prompt({hidden: true}); // '*' is echoed
var password2 = prompt({hidden:true, echo: ''}); // there is no echo
var password3 = prompt({hidden:true, echo: '?'}); // '?' is echoed ####Note
a ^C may be pressed during the input process to abort the text entry and return a null string
