Completion not in the correct order?

[abc123098123]

Hello!

This has been bugging me for a while but, when I use auto-completion, it seems to me that the results are in a reversed order.

Example:

This is the output of company-diag:

Emacs 28.0.50 (x86_64-pc-linux-gnu) of 2020-01-08 on xerxes
Company 0.9.12

company-backends: ((company-lsp company-files))

Used backend: (company-lsp company-files)

Major mode: c++-mode
Prefix: (#("re" 0 1
   (fontified t)
   1 2
   (fontified t))
 . t)

This is my company-lsp configuration:

(use-package company-lsp
    :ensure t
    :commands company-lsp
    :custom
    (company-lsp-cache-candidates t) ;; auto, t(always using a cache), or nil
    (company-lsp-async t)
    (company-lsp-enable-recompletion t)
    :config (push 'company-lsp company-backends))

Thank you very much!

Can confirm. Did you manage to find a fix for this?

Hey @steven-lang

I did not find any fix for this. What I did was to uninstall CCLS and Company-LSP.

Now I use normal LSP mode with Clangd and, honestly, it works very well. I don't see the need of additional stuff when the default settings are pretty great.

@steven-lang company-lsp repo is not active - it is recommended to switch to company-capf.
