Tags merge

[antonkomarev]

This is an enhancement which could be helpful to manage unwanted typos or spellings of the words and remove tags duplicates. For example you have 100 tags formula-1 and 20 tags formula1. You want to leave only formula-1 tag as a valid one and replace all the formula1 tags in all the entities with formula-1. Another one example is merge of plural and singular tags friend or friends.

Here what configuration options I could find usable:

• (bool) Automatically replace on tagging all appearances of formula1 with formula-1.
• Should merge be applied to all types of entities or to only concrete ones (for example apply only for Articles).

I suppose there should be separate database table which will keep all the merge rules.

This can partially be accomplished with the normalizer configuration: if you create a function or class method that can convert formula-1 and formula1 into a normalized string, or friends into friends, then this is already supported when tagging new models.

If you want to do this after the fact (i.e. you already have models that are tagged one way and you want to convert them), then I can add a method to the service class, something like:

TagService::rename('formula1', 'formula-1', \App\Articles::class);

The third argument is an optional classname to restrict the renaming.

Does that make sense?

This is in place on the new 3.x branch (in dev right now). Feel free to checkout dev-master and give it a try.
