For reading user input from stdin.
Similar to the
question() method, but with a few more features.
var read = require("read") read(options, callback)
The callback gets called with either the user input, or the default specified, or an error, as
callback(error, result, isDefault) node style.
Every option is optional.
promptWhat to write to stdout before reading input.
silentDon’t echo the output as the user types it.
replaceReplace silenced characters with the supplied character value.
timeoutNumber of ms to wait for user input before giving up.
defaultThe default value if the user enters nothing.
editAllow the user to edit the default value.
terminalTreat the output as a TTY, whether it is or not.
inputReadable stream to get input data from. (default
outputWriteable stream to write prompts to. (default:
If silent is true, and the input is a TTY, then read will set raw mode, and read character by character.
This module works sort of with node 0.6. It does not work with node versions less than 0.6. It is best on node 0.8.
On node version 0.6, it will remove all listeners on the input stream’s
keypress events, because the readline module did not fully clean up after itself in that version of node, and did not make it possible to clean up after it in a way that has no potential for side effects.
Additionally, some of the readline options (like
terminal) will not function in versions of node before 0.8, because they were not implemented in the builtin readline module.
