## Getting Started

### Installation

Install it with composer

```
composer require dudo1985/wpdocgen --dev
```

## Command Line Usage

First parameter is the input directory, second is the output file, e.g.

#### `vendor/bin/wp-doc-gen . hooks.md`

This will parse all the files in the current directory (.) and write a file called hooks.md

### Optional params

#### `--shortcodes` or `-s`

By default, WPDocGen search for hooks `apply_filters` and `do_actions`.
However, if you use the `--shortcodes` or `-s` will search for `add_shortcode` function instead.

#### `vendor/bin/wp-doc-gen . shortcodes.md -s`

---

#### `--exclude` or `-e`

Exclude the specified folders,  e.g.
#### `vendor/bin/wp-doc-gen . hooks.md --exclude vendor node_modules`

Another example, if you're launching the script from another dir:
#### `vendor bin/wp-doc-gen.php ../my-plugin/ docs/hooks.md --exclude vendor node_modules  --prefix yasr`

There is no need to include the full paths of the excluded dirs, it is automatically ../my-plugin/vendor and 
../my-plugin/node_modules

---

#### `--prefix` or `-p`
Only parse hooks or shortcodes starting with the specified prefixes.

#### `vendor/bin/wp-doc-gen . hooks.md --exclude vendor node_modules --prefix prefix_1 prefix_2`

---

#### `--verbose` or `-v`
More detailed error messages.

---

#### `--version` or `-V`
Print the version number

## Notes
To make the parser work fine, the comment must be a valid phpDocBlock, e.g.

> ```
> /**
> * Use this action to add tabs inside shortcode creator for tinymce
> */
> do_action('yasr_add_tabs_on_tinypopupform');
> ```

will generate this code

>### `do_action('yasr_add_tabs_on_tinypopupform')`
>Source: [../yet-another-stars-rating/admin/editor/YasrEditorHooks.php, line 219](../yet-another-stars-rating/admin/editor//YasrEditorHooks.php:219)
>
>*Use this action to add tabs inside shortcode creator for tinymce*

or, another example with tags

> ``` 
> /**
> * Use this action to add content inside shortcode creator
> *
> * @param int $n_multi_set
> * @param string $multi_set the multiset name
> */
> do_action('yasr_add_content_on_tinypopupform', $n_multi_set, $multi_set);
>```

will generate this code with table

> ### `do_action('yasr_add_content_on_tinypopupform')`
>
> Source: [../yet-another-stars-rating/admin/editor/YasrEditorHooks.php, line 235](../yet-another-stars-rating/admin/editor/YasrEditorHooks.php:235)
> 
> *Use this action to add content inside shortcode creator*
> ```
>
> | Argument     | Type   | Description       |
> |--------------|--------|-------------------|
> | $n_multi_set | int    |                   |
> | $multi_set   | string | the multiset name |
> ```

But, if you use the type *after* the argument, e.g.

> 
> ```
> /**
> * @param $n_multi_set int
> */
> ```
>

this will insert the type (*int* and *string* in this example) inside the "Description" column:

> 
> ```
> | Argument     | Type | Description              |
> |--------------|------|--------------------------|
> | $n_multi_set |      | int                      |
> ```
