Functions

- svg($path)

offering comfortably using svg images in templates, example: {{ svg('awesome_icon.svg') }} when file is stored in "/your-theme-name/images/awesome_icon.svg" and source code of svg will be printed to page as is. This solution is quick and you can use CSS features like ".your-div svg {fill: red}" etc.

- load_block($id)

you can call block by name anywhere in template: {{ load_block('machine_name') }}

- load_region($id)

this function offers print all block of the region anywhere you need: {{ load_region('machine_name') }}

- load_main_node($returnId = true)

solving problem with getting node id from anywhere template when you need it {{ load_main_node() }}

- load_gallery_prev($currentGalleryId, $thumbnailStyle = 'thumbnail')

array with previous media gallery: {{ load_gallery_prev(2) }}

- load_gallery_next($currentGalleryId, $thumbnailStyle = 'thumbnail')

array with next media media: {{ load_gallery_next(1) }}

- load_gallery_thumbs($galleryId, $thumbnailStyle = 'thumbnail')

array with images from gallery: {{ load_gallery_thumbs(5) }}

Filters

- naked_field

return rendered field, for example from view, without developers suggestions (<!-- Hook: etc --->), without HTML tags like <a href="xy">your_filed</a>. Just naked string what you can use as class, data attribute or in twig condition! Using example: {% set badge = content.field_show_badge|naked_field %}

- max_length($max = 0, $dots = true)

Check string length and return him summary or in original. It is pretty alternative to ugly {{ teaser_text|length > 90 ? teaser_text|slice(0, 90) ~ ' ...' : teaser_text }}. By second parameter you can disable adding "..." to the end of string.
