`cape-company-to-capf` wrong cursor focus after completion

[jilen]

With company, after completion(function), the cursor will focus on the first parameter, and can use tab to navigate to next parameter. This behavior is lost after transformed with cape-company-to-capf.

Which company function did you use?

[jilen]

Haven't tried builtin company backends.
But a custom backend defined here https://ensime.github.io/downloads/ensime-tng-3.0.0.tar.gz. Which is a little complicated to setup.

Hm, I cannot find anything related to cursor focus with compeletion-at-point-functions maybe it just impossible to deal with cursor pos after completion.

The post argument expansion, cursor handling happens here:

https://github.com/phillord/ensime-emacs/blob/7ad5cd6957b6a68c4064b74aecd31320bb91b4da/ensime-company.el#L240

It uses yasnippet. cape-company-to-capf calls the post-completion action here:

https://github.com/minad/cape/blob/e5e11f30f0b6ed0a2b283d5d3dec84bcd36557fc/cape.el#L955-L958

In principle this should work. I know for sure that post completion expansion works with cape-company-to-capf for other backends so I assume that it is an issue with either your config or ensime. Can you debug this further?

[jilen]

Ok, let me have a try.

Found it depends on company-template which was not loaded with my setup. Thanks for point out the right direction.
