## read
|
|
|
|
For reading user input from stdin.
|
|
|
|
Similar to the `readline` builtin's `question()` method, but with a
|
|
few more features.
|
|
|
|
## Usage
|
|
|
|
```javascript
|
|
var read = require("read")
|
|
try {
|
|
const result = await read(options, callback)
|
|
} catch (er) {
|
|
console.error(er)
|
|
}
|
|
```
|
|
|
|
## 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.
|
|
* `replace` Replace silenced characters with the supplied character value.
|
|
* `timeout` Number of ms to wait for user input before giving up.
|
|
* `default` The default value if the user enters nothing.
|
|
* `edit` Allow the user to edit the default value.
|
|
* `terminal` Treat the output as a TTY, whether it is or not.
|
|
* `input` Readable stream to get input data from. (default `process.stdin`)
|
|
* `output` Writable stream to write prompts to. (default: `process.stdout`)
|
|
* `completer` Autocomplete callback (see [official api](https://nodejs.org/api/readline.html#readline_readline_createinterface_options) for details
|
|
|
|
If silent is true, and the input is a TTY, then read will set raw
|
|
mode, and read character by character.
