# diff-ini

Compare two INI files for differences. This is both a library and a command-line tool.

[![npm version][3]][4] [![build status][1]][2]  [![dependencies][5]][6] [![devDependencies][7]][8]

## Command-Line

#### Install

```
npm install -g diff-ini
```

#### Usage

```
diff-ini path/to/old.ini path/to/new.ini
```

When a `key` changes:

```
-key = bad
+key = bar
```

When a `key` changes inside of a `section`:

```
-section/key = old
+section/key = new
```

When a `section` is erased:

```
-section/one/key = value
```

When a `section` is added:

```
+section/two/key = value
```


## Library

#### Install as a Library

```
npm install diff-ini
```

#### Usage

```javascript
var diff = require('diff-ini');

diff(process.argv[2], process.argv[3], function(error, result) {
    if (error) {
        console.error('File not found: "%s"', error.path);
    } else {
        diff.print(result);
    }
});
```

#### API

###### diff(strOldFile, strNewFile, fnDone)
Calculate the differences between strOldFile and strNewFile. Call `fnDone(error, resultArray)` when done, or an error occurs.

###### diff.print(result, [log])
Print the differences in a somewhat useful way. Output is sent to `process.stdout` or `log(str)` if you define one.

# TODO
Probably tons! It's working the way I need it to right now, so let me know if you need something.
