# tree-match-sync
> Match files using glob patterns synchronously

[![NPM Version][npm-image]][npm-url] [![Build Status][travis-image]][travis-url] [![Dependencies Status][dependencies-image]][dependencies-url] [![devDependencies Status][devDependencies-image]][devDependencies-url]

You don't have to use the File System API to find files, just use this module!

Under the hood it spawns a `tree` command synchronously, matches files using glob patterns and then you can handle the result stored in a var :wink:

## Installation
```sh
$ npm install tree-match-sync
```
tree-match-sync depends on the `tree` command, if it's not installed run one of these commands based on your OS:

- Debian, Ubuntu (and any other `apt-get` based distro)
```sh
apt-get install tree
```
- openSUSE
```sh
zypper install tree
```
- Fedora, CentOS, RHEL (and any other `yum` or `dnf` based distro):
```sh
## Fedora <= 21, CentOS, RHEL
yum install tree
## Fedora >= 22
dnf install tree
```
- Mac OS, with [Homebrew](http://brew.sh/)
```sh
brew install tree
```
- Windows
```sh
bin\tree.exe
```
Included in the package, provided by [GnuWin32](http://gnuwin32.sourceforge.net/packages/tree.htm).

## Usage
```javascript
var treeMatch = require('tree-match-sync');

var tree = treeMatch(directory, pattern, options);

if(Object.prototype.toString.call(tree) === '[object Object]'){
  console.error(tree);
}else{
  console.log(tree);
}
```
As you can see there are three arguments:

1. `directory`: the path of the folder that you want to search in, the current working directory is your app location;
1. `pattern`: [glob pattern](https://tr.im/glob), using [minimatch](https://github.com/isaacs/minimatch), use only its [features](https://github.com/isaacs/minimatch#features);
1. `options`: minimatch's [options](https://github.com/isaacs/minimatch#options) with an extra field, `maxDepth: int` that translates to `tree`'s option `-L level` - `Descend only level directories deep`. I recommend you to always set this field when you don't know how many files may be contained in `directory`.

The output may be an Array (all went good) or an Object (an error occured).

The Array contains the matched file names.

The Object has two fields:

1. `status`: the exit code of `tree`;
1. `stderr`: the error message.


There's also a function that controls if the `tree` command is installed:
```javascript
var treeMatch = require('tree-match');

if(treeMatch.treeIsInstalled()){
  // OK, tree is installed, do something!
}else{
  // Well, tree isn't installed...
}
```
It has no arguments and returns `true`/`false`.

## Examples
```javascript
var treeMatch = require('tree-match-sync');

var tree = treeMatch('./test', '**/*.js');

if(Object.prototype.toString.call(tree) === '[object Object]'){
  console.error(tree);
}else{
  console.log(tree);
  // => [ 'test.js' ]
}
```
---
```javascript
var treeMatch = require('tree-match-sync');

var tree = treeMatch('./test', '**/*.js', { maxDepth: 0 });

if(Object.prototype.toString.call(tree) === '[object Object]'){
  console.error(tree);
  // => { status: 1, stderr: 'tree: Invalid level, must be greater than 0.\n' }
}else{
  console.log(tree);
}
```
