Kirby TranslatedLayout field plugin

This plugin brings translation logics into the native layouts fields.

Experimental

While the kirby team is waiting for some heavy refactoring for recursively bringing translation logics into their "complex fields", this plugin aims to provide a temporary workaround for multi-language websites.

This is an experimental draft trying to bring some translation logic to blocks, columns and layouts. It turns out to be quite powerful already with just a minimal set of changes compared to the native field behaviour.

Current state :
Tested on a single configuration, works well but not extensively tested. Therefore, please note that there remains a risk of data loss. (Do not use without backups!)
There is no translatedblocks fields nor toTranslatedBlocks method (yet?), please use layouts instead.

Implementation

• The primary language (default) inherits the default LayoutField behaviour and remains (almost?) identical to the native Kirby Layout field.
• The seconday languages (translations) of this field are always syncronized on parse (aka $field->fill($value)).
  • Identical structures : The layouts and blocks structures are defined by the default language using their unique id.
  • Fallback : If a block has no translation, it's replaced with the default language.
  • Sanitation : If a block translation is not available in the default language, it's removed. All blocks from the default language are guaranteed to be available for translation in the panel.
  • Panel GUI : Non-translateable fields and blocks are disabled, preventing panel users from changing the layout and adding blocks in translations.
  • Data : The syncronized translation is saved as a blocks and columns array and parsed on retrieval. (this saves some disk space and makes data more readable).

Requirements

• Version 0.3.3-beta : Kirby 3.8 or above.
• (Kirby 4 compatibility should be easy to implement; mainly a few changed function signatures and namespace renames)

• Version 1.0.0 : Kirby 5 or above.

• Note: This plugin heavily relies on the use of the panel. If you'd like to manually edit a translatedlayout field via the text content file, it's not recommended to use this plugin, as it's probably not recommended to use blocks without the panel. (Meanwhile, it still is possible, and this plugin even simplifies the translation files).

Installation

Choose one:

• Download: Download and copy this repository to /site/plugins/translatedlayout.
• Git submodule: git submodule add https://github.com/daandelange/kirby-translatedlayout.git site/plugins/translatedlayout.
• Composer: composer require daandelange/translatedlayout.

Setup

Import existing data

• The default language saves as the native Kirby layouts field.
• Translations have a different content structure and only save the translated block fields.

Warning! If you already have a layout with translated content, switching to this field will erase all translations unless you manually give the same id to blocks/rows/columns in the translations data structure. There is no automatic script available.
The same happens when you change the default language so make sure it's correct, and to never change it again.

Blueprints

In your page blueprints, you can simply replace a type: layout field by type: translatedlayout. Read more about how to use the respective fields in the official Kirby docs.

The only difference is an extra translate property on fields, please refer to this example:

`

To use predefined translation settings for the default kirby blocks, you may use :

` This can be useful for quickly setting up this plugin in a test environment.
Beware that this will add the fields to your fieldsets if they don't exist yet.

To setup your own fieldsets, prefer copy/pasting from translatedlayoutwithfieldsets.yml and adapt it to your needs.

Templates

Use $field->toTranslatedLayout() in your templates to fetch & render the field contents. Like the native LayoutField's toLayouts, a Kirby\Cms\Layouts object is returned. There is absolutely no difference as the plugin acts during the data parse state.

Options

There are no options available yet. Would you like to contribute some ?

Development

• A small hack to fix KirbyUp's alias @KirbyPanel sub-includes : (more info)
  • osx: cd /path/to/translatedLayout/ && ln -s "../../../../kirby/panel/src/mixins" ./src/mixins
  • linux: todo
  • other: Create an alias/symlink pointing from translatedlayout/src/mixins to /kirby/panel/src/mixins.
• npm install : Install the required dependencies.
• npm run dev : Develop mode (listen/compile).
• npm run build : Compile for publishing.

Feature ideas

• Plugin options : Set rather to fill with (untranslated) default language, or leave the translateable blocks empty ? (on translation creation only).
• Write some test cases.

Similar Plugins

• Synced-Structure : Syncs structures across languages using UUIDs. Note: This method doesn't work with Layouts and Blocks fields because they use the FieldClass instead of Kirby's field blueprints.
