How do I hide noisy completion messages in Vim's command line?

Explanation

Insert-mode completion can spam the command line with status text like "match 1 of N" and related prompts. That feedback is sometimes useful, but in large files or fast completion workflows it becomes visual noise and pushes out more relevant messages. :set shortmess+=c suppresses completion-menu chatter so the command area stays quieter and easier to scan.

How it works

• shortmess is a compact-message option controlled by single-letter flags
• +=c adds only the c flag, which suppresses specific completion messages
• Using += is important because it preserves your existing shortmess tuning
• The setting applies immediately and can be made persistent in your vimrc/init.vim

Example

Without the setting, repeatedly triggering completion may print transient status messages after each attempt. After running:

:set shortmess+=c

completion still works normally, but those command-line updates are reduced, leaving room for diagnostics, search feedback, and your own :echo output.

Tips

• Inspect current flags with :set shortmess?
• Revert just this tweak with :set shortmess-=c
• Keep this as a local experiment first, then persist it once you confirm it matches your completion workflow
