Title Case Suggestions
This module automatically suggests title casing for article titles as they are entered, using a third-party service. Authors can disable this feature to manually control capitalization. It can also optionally copy the suggested title to an "index title" field if one exists.
Sets article titles to have recommended title casing when an article title is filled in.
The author can uncheck a box to regain control of capitalization. Currently, there is no button to undo the automatic capitalization that was done.
This uses a third-party service - https://titlecaseconverter.com/ - that you need to sign up for and add a credit card (100 API usages a month are free) - https://rapidapi.com/Matt11/api/title-case-converter
Currently there is no settings interface, to provide the API key add it to your settings.local.php file:
$config['titlecasesuggestions.settings']['rapidapi_key'] = 'Your RapidAPI TitleCaseConverter Application Key';
Would be very interested in swapping out the 3rd-party service for an open source free/libre software alternative, but looks like someone would have to write that.
Bonus feature: Copies the title to an "index title" used to give a shorter version of the title, if this field exists. If others are interested in this feature we can make it configurable, please open an issue.
