Support typeahead suggestions with spaces in search terms (e.g. @firstname lastname)

[sarah-liang]

I’m interested in using the typeahead plugin for cases where suggestions may contain spaces, such as mentioning users by full name (e.g., @firstname lastname). Currently, the typeahead seems to match only single “words” without spaces after the trigger.

Would it be possible to add support for typeahead suggestions where the search term contains spaces? For example, typing @first l would offer @First Last as a match and allow inserting the full name including the space.

This would be really useful for cases like user mentions, tags with spaces, or other multi-word entries.

This could possibly be supported by allowing the users to configure the allowed (or ignored) escape characters or a trigger regex string.

I have been using this module with a patch to remove space from the regex for triggering escape, as I have the same use case of wanting to be able to search with first and last names.

It would be great to support taking a custom set of characters that trigger escape (or don't).

As an example if creating something to search email addresses typing @jane.doe would escape the typeahead at the period.

I'm happy to accept a PR on the matter.
