Question 1

How do I set up cmp-cmdline for search and command completions in Neovim?

Accepted Answer

Follow the Lua configuration examples in the README: set up sources for '/' with buffer completions and for ':' with path and cmdline sources, ensuring cmp-buffer is installed for buffer support. It's straightforward but requires careful integration with nvim-cmp.

Question 2

What's the difference between cmp-cmdline and native Vim command-line completion?

Accepted Answer

cmp-cmdline integrates with nvim-cmp to provide more intelligent, context-aware suggestions based on buffer content and commands, whereas native Vim completion is more basic and less configurable, often requiring manual triggers.

Question 3

Can I use cmp-cmdline to complete file paths in Neovim?

Accepted Answer

Yes, by integrating cmp-path as a source in the ':' cmdline setup, cmp-cmdline can suggest file paths, and it handles trailing slashes with the treat_trailing_slash option to streamline directory navigation.

Question 4

How to exclude certain commands from appearing in completions with cmp-cmdline?

Accepted Answer

Use the ignore_cmds option in the cmdline source setup to list command names you want to ignore, such as 'Man' or '!', which is demonstrated in the README example for customizing completions.

Question 5

Does cmp-cmdline work with other nvim-cmp sources like cmp-buffer?

Accepted Answer

Yes, it's designed to work seamlessly with other nvim-cmp sources, allowing you to combine buffer, path, and cmdline completions for a comprehensive setup, as shown in the configuration snippets.

Question 6

Is cmp-cmdline suitable for large codebases or slow on big files?

Accepted Answer

Since it relies on vim.fn.getcompletion, performance may vary with buffer size; it's generally efficient for typical use, but very large buffers could experience slower suggestion times due to Vim's internal mechanisms.

Question 7

cmp-cmdline or cmp-buffer: which one do I need for command-line completions?

Accepted Answer

cmp-cmdline is specifically for command-line mode ('/' and ':'), while cmp-buffer is for insert mode completions; you'll need both for full buffer-based suggestions across modes, as they serve different purposes in the nvim-cmp ecosystem.
