node-teen_process
=================
A grown-up version of Node's child_process. `exec` is really useful, but it
suffers many limitations. This is an es7 (`async`/`await`) implementation of
`exec` that uses `spawn` under the hood. It takes care of wrapping commands and
arguments so we don't have to care about escaping spaces. It can also return
stdout/stderr even when the command fails, or times out. Importantly, it's also
not susceptible to max buffer issues.
## teen_process.exec
Examples:
```js
import { exec } from 'teen_process';
// basic usage
let {stdout, stderr, code} = await exec('ls', ['/usr/local/bin']);
console.log(stdout.split("\n")); // array of files
console.log(stderr); // ''
console.log(code); // 0
// works with spaces
await exec('/command/with spaces.sh', ['foo', 'argument with spaces'])
// as though we had run: "/command/with spaces.sh" foo "argument with spaces"
// nice error handling that still includes stderr/stdout/code
try {
await exec('echo_and_exit', ['foo', '10']);
} catch (e) {
console.log(e.message); // "Exited with code 10"
console.log(e.stdout); // "foo"
console.log(e.code); // 10
}
```
The `exec` function takes some options, with these defaults:
```js
{
cwd: undefined,
env: process.env,
timeout: null,
killSignal: 'SIGTERM',
encoding: 'utf8',
ignoreOutput: false,
stdio: "inherit",
isBuffer: false,
shell: undefined,
logger: undefined,
maxStdoutBufferSize: 100 * 1024 * 1024, // 100 MB
maxStderrBufferSize: 100 * 1024 * 1024, // 100 MB
}
```
Most of these are self-explanatory. `ignoreOutput` is useful if you have a very
chatty process whose output you don't care about and don't want to add it to
the memory consumed by your program.
Both buffer size limits are needed to avoid memory overflow while collecting
process output. If the overall size of output chunks for different stream types exceeds the the given one then the oldest chunks will be pulled out in order to keep the memory load within the acceptable ranges.
If you're on Windows, you'll want to pass `shell: true`, because `exec`
actually uses `spawn` under the hood, and is therefore subject to the issues
noted about Windows + `spawn` in [the Node
docs](https://nodejs.org/api/child_process.html).
If `stdio` option is not set to `inheirt`, you may not get colored output from your process. In this case you can explore the subprocess's documentation to see if an option like `--colors` or `FORCE_COLORS` can be specified. you can also try to set `env.FORCE_COLOR = true` and see if it works.
Example:
```js
try {
await exec('sleep', ['10'], {timeout: 500, killSignal: 'SIGINT'});
} catch (e) {
console.log(e.message); // "'sleep 10' timed out after 500ms"
}
```
The `isBuffer` option specifies that the returned standard I/O is an instance
of a [Buffer](https://nodejs.org/api/buffer.html).
Example:
```js
let {stdout, stderr} = await exec('cat', [filename], {isBuffer: true});
Buffer.isBuffer(stdout); // true
```
The `logger` option allows stdout and stderr to be sent to a particular logger,
as it it received. This is overridden by the `ignoreOutput` option.
## teen_process.SubProcess
`spawn` is already pretty great but for some uses there's a fair amount of
boilerplate, especially when using in an `async/await` context. `teen_process`
also exposes a `SubProcess` class, which can be used to cut down on some
boilerplate. It has 2 methods, `start` and `stop`:
```js
import { SubProcess } from 'teen_process';
async function tailFileForABit () {
let proc = new SubProcess('tail', ['-f', '/var/log/foo.log']);
await proc.start();
await proc.stop();
}
```
Errors with start/stop are thrown in the calling context.
### Events
You can listen to 8 events:
* `exit`
* `stop`
* `end`
* `die`
* `output`
* `lines-stdout`
* `lines-stderr`
* `stream-line`
```js
proc.on('exit', (code, signal) => {
// if we get here, all we know is that the proc exited
console.log(`exited with code ${code} from signal ${signal}`);
// exited with code 127 from signal SIGHUP
});
proc.on('stop', (code, signal) => {
// if we get here, we know that we intentionally stopped the proc
// by calling proc.stop
});
proc.on('end', (code, signal) => {
// if we get here, we know that the process stopped outside of our control
// but with a 0 exit code
});
proc.on('die', (code, signal) => {
// if we get here, we know that the process stopped outside of our control
// with a non-zero exit code
});
proc.on('output', (stdout, stderr) => {
console.log(`stdout: ${stdout}`);
console.log(`stderr: ${stderr}`);
});
// lines-stderr is just the same
proc.on('lines-stdout', lines => {
console.log(lines);
// ['foo', 'bar', 'baz']
// automatically handles rejoining lines across stream chunks
});
// stream-line gives you one line at a time, with [STDOUT] or [STDERR]
// prepended
proc.on('stream-line', line => {
console.log(line);
// [STDOUT] foo
});
// so we could do: proc.on('stream-line', console.log.bind(console))
```
### Start Detectors
How does `SubProcess` know when to return control from `start()`? Well, the
default is to wait until there is some output. You can also pass in a number,
which will cause it to wait for that number of ms, or a function (which I call
a `startDetector`) which takes stdout and stderr and returns true when you want
control back. Examples:
```js
await proc.start(); // will continue when stdout or stderr has received data
await proc.start(0); // will continue immediately
let sd = (stdout, stderr) => {
return stderr.indexOf('blarg') !== -1;
};
await proc.start(sd); // will continue when stderr receives 'blarg'
```
A custom `startDetector` can also throw an error if it wants to declare the
start unsuccessful. For example, if we know that the first output might contain
a string which invalidates the process (for us), we could define a custom
`startDetector` as follows:
```js
let sd = (stdout, stderr) => {
if (/fail/.test(stderr)) {
throw new Error("Encountered failure condition");
}
return stdout || stderr;
};
await proc.start(sd); // will continue when output is received that doesn't
// match 'fail'
```
Finally, if you want to specify a maximum time to wait for a process to start,
you can do that by passing a second parameter in milliseconds to `start()`:
```js
// use the default startDetector and throw an error if we wait for more than
// 1000ms for output
await proc.start(null, 1000);
```
### Finishing Processes
After the process has been started you can use `join()` to wait for it to
finish on its own:
```js
await proc.join(); // will throw on exitcode not 0
await proc.join([0, 1]); // will throw on exitcode not 0 or 1
```
And how about killing the processes? Can you provide a custom signal, instead
of using the default `SIGTERM`? Why yes:
```js
await proc.stop('SIGHUP');
```
If your process might not be killable and you don't really care, you can also
pass a timeout, which will return control to you in the form of an error after
the timeout has passed:
```js
try {
await proc.stop('SIGHUP', 1000);
} catch (e) {
console.log("Proc failed to stop, ignoring cause YOLO");
}
```
All in all, this makes it super simple to, say, write a script that tails
a file for X seconds and then stops, using async/await and pretty
straightforward error handling.
```js
async function boredTail (filePath, boredAfter = 10000) {
let p = new SubProcess('tail', ['-f', filePath]);
p.on('stream-line', console.log);
await p.start();
await Bluebird.delay(boredAfter);
await p.stop();
}
```

# Introduction
Bluebird is a fully featured promise library with focus on innovative features and performance
See the [**bluebird website**](http://bluebirdjs.com/docs/getting-started.html) for further documentation, references and instructions. See the [**API reference**](http://bluebirdjs.com/docs/api-reference.html) here.
For bluebird 2.x documentation and files, see the [2.x tree](https://github.com/petkaantonov/bluebird/tree/2.x).
### Note
Promises in Node.js 10 are significantly faster than before. Bluebird still includes a lot of features like cancellation, iteration methods and warnings that native promises don't. If you are using Bluebird for performance rather than for those - please consider giving native promises a shot and running the benchmarks yourself.
# Questions and issues
The [github issue tracker](https://github.com/petkaantonov/bluebird/issues) is **_only_** for bug reports and feature requests. Anything else, such as questions for help in using the library, should be posted in [StackOverflow](http://stackoverflow.com/questions/tagged/bluebird) under tags `promise` and `bluebird`.
## Thanks
Thanks to BrowserStack for providing us with a free account which lets us support old browsers like IE8.

# which
Like the unix `which` utility.
Finds the first instance of a specified executable in the PATH
environment variable. Does not cache the results, so `hash -r` is not
needed when the PATH changes.
## USAGE
```javascript
var which = require('which')
// async usage
which('node', function (er, resolvedPath) {
// er is returned if no "node" is found on the PATH
// if it is found, then the absolute path to the exec is returned
})
// or promise
which('node').then(resolvedPath => { ... }).catch(er => { ... not found ... })
// sync usage
// throws if not found
var resolved = which.sync('node')
// if nothrow option is used, returns null if not found
resolved = which.sync('node', {nothrow: true})
// Pass options to override the PATH and PATHEXT environment vars.
which('node', { path: someOtherPath }, function (er, resolved) {
if (er)
throw er
console.log('found at %j', resolved)
})
```
## CLI USAGE
Same as the BSD `which(1)` binary.
```
usage: which [-as] program ...
```
## OPTIONS
You may pass an options object as the second argument.
- `path`: Use instead of the `PATH` environment variable.
- `pathExt`: Use instead of the `PATHEXT` environment variable.
- `all`: Return all matches, instead of just the first one. Note that
this means the function returns an array of strings instead of a
single string.
