I am using neovim with coc.nvim installed. How do I disable the fillers/placeholders in the functions?

Thanks in advance.

Os: Linux Mint

my coc-settings.json:

{
  "jedi.enable": true,
  "jedi.startupMessage": false,
  "jedi.markupKindPreferred": "plaintext",
  "jedi.trace.server": "off",
  "jedi.jediSettings.autoImportModules": [],
  "jedi.executablemand": "jedi-language-server",
  "jedi.executable.args": [],
  "jedipletion.disableSnippets": false,
  "jedipletion.resolveEagerly": false,
  "jedi.diagnostics.enable": true,
  "jedi.diagnostics.didOpen": true,
  "jedi.diagnostics.didChange": true,
  "jedi.diagnostics.didSave": true,
  "jedi.workspace.extraPaths": [],
  "jedi.jediSettings.caseInsensitiveCompletion": false,
  "clangd.path": "~/.config/coc/extensions/coc-clangd-data/install/18.1.3/clangd_18.1.3/bin/clangd",
  "clangd.arguments": [
        "--function-arg-placeholders=0"
    ],

  "inlayHint.enable": false

I myself was looking for this feature. I took this from your coc-settings.json:

"clangd.arguments": [
  "--function-arg-placeholders=0"
]

And it worked for me!!

Seems like this isn't working for you because of older clangd version. My clangd version is 18.1.8 whereas your clangd version is 18.1.3.

I think you should update your clangd in order to get this work. If still this doesn't help, try to updating coc.nvim as well.

See this for more info.

From Vim, use the command :CocConfig to open the coc-settings.json file for the current settings. Add the options below and restart Vim or run :CocRestart. This should disable the hints.

For more information, refer to :h coc-inlayhint.

Note: Setting "inlayHint.enable": false will disable function argument hints. However, I only wanted to disable specific information, so I used the following configuration:

  "diagnostic.enable": false,
  "signature.enable": false,
  "inlayHint.enable": false,
