How to use company-yasnippet before company-ispell?

[zhenhua-wang]

I would like to get completion from company-yasnippet first. If no completion find, then switch to company-ispell. However, with the following config, company-ispell is completely blocked by company-yasnippet. Is there any way to achieve this? Thanks for any help.

(setq company-backends '(company-files
         company-capf
         company-yasnippet
         company-ispell))

There are basically two ways to do that:

• Write your own backend which will be a simple wrapper that calls both backends and returns the completions from the one that has them.
• Add an advice to company-yasnippet to add special handling to the prefix method which would call the logic in candidates right away, and if nothing's found, return nil from prefix already.

You could also try using M-x company-other-backend, which is a command to be used explicitly (through a key binding of your choice) that iterates through the backends in the list and will make sure you get to the one that returns some completions.
