set blocking `stdio` and `stderr` ensuring that terminal output does not truncate.
|
|
|
|
```js
|
|
const setBlocking = require('set-blocking')
|
|
setBlocking(true)
|
|
console.log(someLargeStringToOutput)
|
|
```

## Historical Context/Word of Warning
|
|
|
|
This was created as a shim to address the bug discussed in [node #6456](https://github.com/nodejs/node/issues/6456). This bug crops up on
|
|
newer versions of Node.js (`0.12+`), truncating terminal output.
|
|
|
|
You should be mindful of the side-effects caused by using `set-blocking`:
|
|
|
|
* if your module sets blocking to `true`, it will effect other modules
|
|
consuming your library. In [yargs](https://github.com/yargs/yargs/blob/master/yargs.js#L653) we only call
|
|
`setBlocking(true)` once we already know we are about to call `process.exit(code)`.
|
|
* this patch will not apply to subprocesses spawned with `isTTY = true`, this is
|
|
the [default `spawn()` behavior](https://nodejs.org/api/child_process.html#child_process_child_process_spawn_command_args_options).
