## Component Status

Prototype.

## Motivation

Do lightweight editing on YAML files and then rewrite the file without losing embedded comments.

## Usage

```

// First step: read the file, parse the yaml, edit and dump the results.

$original_contents = file_get_contents($filepath);

$parsed_data = Yaml::parse($original_contents);

$processed_data = $this->my_processing_function($parsed_data);

$altered_contents = Yaml::dump($parsed_data, PHP_INT_MAX, 2, Yaml::DUMP_MULTI_LINE_LITERAL_BLOCK);

// Second step: collect comments from original document and inject them into result.

$commentManager = new Comments();

$commentManager->collect(explode("\n", $original_contents));

$altered_with_comments = $commentManager->inject(explode("\n", $altered_contents));

$result = implode("\n", $altered_with_comments);

```

## Limitations

The comment manager collects groups of comment lines and associates them with the first non-blank content line that follows the comment. If there are multiple non-blank content lines that are exactly the same, then the comment lines are re-injected in the same order they appeared in the original file.

## Installation

$ composer require consolidation/comments
