For reading user input from stdin.
|
||
|
|
|
||
|
|
## USAGE
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var read = require("read")
|
||
|
|
read(options, callback)
|
||
|
|
```
|
||
|
|
|
||
|
|
The callback gets called with either the user input, or the default
|
||
|
|
specified, or an error, in the traditional `callback(error, result)`
|
||
|
|
node style.
|
||
|
|
|
||
|
|
## OPTIONS
|
||
|
|
|
||
|
|
Every option is optional.
|
||
|
|
|
||
|
|
* `prompt` What to write to stdout before reading input.
|
||
|
|
* `silent` Don't echo the output as the user types it.
|
||
|
|
* `num` Max number of chars to read from terminal.
|
||
|
|
* `delim` The char that means we're done. Default: `"\n"`
|
||
|
|
* `timeout` Number of ms to wait for user input before giving up.
|
||
|
|
* `default` The default value if the user enters nothing.
|
||
|
|
|
||
|
|
If silent is true, or num is set, or delim is something other than
|
||
|
|
`"\n"`, then read will set raw mode, and read character by character.
|
||
|
|
|
||
|
|
At this time, backspace and arrow keys are not supported in raw mode.
|
||
|
|
It's probably not too hard to add support for this, perhaps using node's
|
||
|
|
built-in readline module.

|
## BUGS
|
||
|
|
|
||
|
|
In node 0.6.0 through 0.6.5, you must explicitly call
|
||
|
|
`process.stdin.destroy()` or `process.exit()` when you know that your
|
||
|
|
program is done reading, or else it will keep the event loop running
|
||
|
|
forever.
