# resolveParentPaths

> Resolve paths from a set of paths by walking parent directories.

<section class="usage">

## Usage

```javascript
var resolveParentPaths = require( '@stdlib/fs/resolve-parent-paths' );
```

<a name="resolve-parent-paths"></a>

#### resolveParentPaths( paths\[, options], clbk )

Asynchronously resolves paths from a set of paths by walking parent directories.

```javascript
resolveParentPaths( [ 'package.json', 'package-lock.json' ], onPaths );

function onPaths( error, paths ) {
if ( error ) {
throw error;
}
console.log( paths );
// => '...'
}
```

The function accepts the following `options`:

- **dir**: base directory from which to begin walking. May be either an absolute path or a path relative to the current working directory.

- **mode**: mode of operation. The following modes are supported:

- `first`: return the first resolved path.
- `some`: return one or more paths resolved within the first directory level containing a match.
- `all`: return all resolved paths within the first directory level containing matches for all provided paths.
- `each`: independently return the first resolved path for each path at any directory level.

Default: `'all'`.

By default, the function begins walking from the current working directory. To specify an alternative directory, set the `dir` option.

```javascript
var opts = {
'dir': __dirname
};
resolveParentPaths( [ 'package.json' ], opts, onPaths );

function onPaths( error, paths ) {
if ( error ) {
throw error;
}
console.log( paths );
// => '...'
}
```

By default, the function requires that a directory contains matches for all provided paths before returning results. To specify an alternative operation mode, set the `mode` option.

```javascript
var opts = {
'dir': __dirname,
'mode': 'first'
};
resolveParentPaths( [ 'package.json', 'package-lock.json' ], opts, onPaths );

function onPaths( error, paths ) {
if ( error ) {
throw error;
}
console.log( paths );
// => '...'
}
```

#### resolveParentPaths.sync( paths\[, options] )

Synchronously resolves paths from a set of paths by walking parent directories.

```javascript
var paths = resolveParentPaths.sync( [ 'package.json', 'README.md' ] );
// returns [ '...', '...' ]
```

The function accepts the same `options` as [`resolveParentPaths()`](#resolve-parent-paths).

<!-- /.usage -->

<section class="notes">

## Notes

- In `some` mode, the return order of asynchronously resolved paths is not guaranteed.
- This implementation is **not** similar in functionality to core [`path.resolve`][node-core-path-resolve]. The latter performs string manipulation to generate a full path. This implementation walks parent directories to perform a **search**, thereby touching the file system. Accordingly, this implementation resolves _real_ absolute file paths and is intended for use when a target's location in a parent directory is unknown relative to a child directory; e.g., when wanting to find a package root from deep within a package directory.

## Examples

<!-- eslint no-undef: "error" -->

```javascript
var resolveParentPaths = require( '@stdlib/fs/resolve-parent-paths' );

var opts = {
'dir': __dirname
};

/* Sync */

var out = resolveParentPaths.sync( [ 'package.json', 'README.md' ], opts );
// returns [ '...', '...' ]

out = resolveParentPaths.sync( [ 'non_existent_basename' ], opts );
// returns []

opts.mode = 'first';
out = resolveParentPaths.sync( [ 'non_existent_basename', 'package.json' ], opts );
// returns [ '...' ]

/* Async */

resolveParentPaths( [ 'package.json', 'README.md' ], opts, onPaths );
resolveParentPaths( [ './../non_existent_path' ], onPaths );

function onPaths( error, paths ) {
if ( error ) {
throw error;
}
console.log( paths );
}
```
