Get all headings for table of contents

[Wulfheart]

Hello,

is it possible to get all headings from a string in an extension? I need this for autogenerating a table of contents.

Thank you in advance

There is an implementation of this in yii2-apidoc package:

https://github.com/yiisoft/yii2-apidoc/blob/e56aa1f065e4ece1a68b21de653b02ed0da2dadd/helpers/ApiMarkdown.php#L94-L121

could be useful to extract this into a trait and add it to this package. Happy to review and merge pull requests for this.

@akshitagupta20 Hi, thanks for offering help. The solution would be a trait, that can be added to a custom markdown class:

<?php

class MyCustomMarkdown extends Markdown
{
     use HeadlineExtractionTrait;
// ..
}

HeadlineExtractionTrait should be a class from this repo and should contain the code similar to the one linked above, providing the collection of headlines as well as a getHeadlines() method.

Hope that is clear, feel free to ask more detailed question.
