Sub Modifier
============

[](#sub-modifier)

SubModifier modifies subtitle files by increasing or decreasing the subtitle files and by re-indexing the subtitles (in case a subtitle file has to be split up for multi-part movies).

*Currently only supports `.srt` files.*

Installation
------------

[](#installation)

If you want to use this as a package for a separate project (assuming composer was installed globally):

```
composer require mihaeu/sub-modifier:1.*
```

In most cases however this is more useful installed globally along with other tools like phpunit, phing, etc. as a global script:

```
composer global require mihaeu/sub-modifier:1.*
```

Make sure the global composer path (usually `~/.composer/bin`) is in your `$PATH`.

```
echo $PATH
```

Usage
-----

[](#usage)

```
submod
```

Assuming I'm in a movie directory with a subtitle that I want to delay by 10 seconds, I would do the following (overwriting the old file):

```
submod Amour-2012.srt 00:10:00,000 > Amour-2012.srt
```

Tests
-----

[](#tests)

Run the PHPUnit tests from the project root like so:

```
vendor/bin/phpunit --testdox --coverage-text
```

To get readable output like this (requires for you to have code coverage in your php setup, otherwise, remove that option):

```
