Disable autoexpansion of snippets when completing

[asmodeus812]

According to the docs we could do that with

	- "disableSnippetCompletion": Disable snippet completion feature for
	  this languageserver.

However having this in my coc settings, does not work

    "languageserver.disableSnippetCompletion": true,           // not working / applied for all servers 
    "languageserver.java.disableSnippetCompletion": true,      // not working even with specific server

What is the correct way to disable the expansion on functions/symbols arguments/paramters, but retain / keep the expansion of snippets.

I would like to avoid the null arguments (see below) being automatically added by coc

   Collections.addAll(null, null)

[fannheyward]

The disableSnippetCompletion configuration is used for languageserver section, something like

"languageserver": {
  "clangd": {
    "command": "clangd",
    "disableSnippetCompletion": true,
    "rootPatterns": ["compile_flags.txt", "compile_commands.json"],
    "filetypes": ["c", "cc", "cpp", "c++", "objc", "objcpp"]
  }
}

[fannheyward]

For the Collections.addAll issue, are you using coc-java? I don't think coc-java supports to disable snippets, the disableSnippetCompletion won't work for it.

[asmodeus812]

Is it not possible to simply disable the client capability for snippets? Can't cocs client simply announce it does not support snippet expansion ? At least with the nvim native lsp, that is how we used to disable certain capabilities globally.

[fannheyward]

Use suggest.snippetsSupport to disable snippets completion.

@fannheyward well yes but this breaks code snippets provided by the lang server, for (${1:int} ${2:i} = ${3:0}; ${2:i} < ${4:array.length}; ${2:i}++). Does coc support integration with something like luasnip and friendly snippets ?

Edit: I did try coc-snippets, but since snippet completion is disabled, it would not expand code snippets like it does not for ones coming from the language server itself.

If there is a way to tell coc to expand the snippets (on tab/enter) but not the function params / arguments that would be great

[fannheyward]

coc-snippets can use friendly snippets.

tell coc to expand the snippets (on tab/enter) but not the function params / arguments

There're both snippets. Needs a configuration to disable server returns params as snippets, disableSnippetCompletion is used for this.
