How to call cmp.setup.cmdline and cmp.setup.filetype?

[NickHu]

nvim-cmp has a feature that allows you to provide a different setup for cmp in the context of the cmdline or specific filetypes rather than insert mode (e.g. to have different sources - see https://github.com/hrsh7th/cmp-cmdline). I don't think this is exposed in the cmp plugin, but is there a way to do this anyway?

Hi !
I have started to look at this issue.
For now, I would suggest you to write this part in lua using extraConfigLua.

This is my implementation for nvim-cmp. I will share my flake when it is complete.

# LSP autocompletion
nvim-cmp = {
	enable = true;
	snippet.expand = "luasnip";
	mapping = {
		"<C-d>" = "cmp.mapping.scroll_docs(-4)";
		"<C-f>" = "cmp.mapping.scroll_docs(4)";
		"<C-e>" = "cmp.mapping.close()";
		"<C-space>" = "cmp.mapping.complete()";
		"<C-y>" = {
			action = "cmp.mapping.confirm({
				select = true, behavior = cmp.ConfirmBehavior.Insert })";
		};
	};
	window.documentation.border = [
		"╭" "─" "╮" "│" "╯" "─" "╰" "│"
	];
	sources = [
		{ name = "nvim_lua"; }
		{ name = "nvim_lsp"; }
		{ name = "cmdline"; }
		{ name = "path"; }
		{ name = "luasnip"; }
		{ name = "buffer"; }
	];
};
cmp-buffer.enable = true;
cmp-nvim-lsp.enable = true;
cmp-nvim-lua.enable = true; 
cmp-cmdline.enable = true;
cmp-path.enable = true;
luasnip.enable = true;

extraConfigLua = ''
-- Extra options for cmp-cmdline setup
local cmp = require('cmp')
cmp.setup.cmdline(':', {
	mapping = cmp.mapping.preset.cmdline(),
	sources = cmp.config.sources({
		{ name = 'path' }
	}, {
		{
			name = 'cmdline',
			option = {
				ignore_cmds = { 'Man', '!' }
			}
		}
	})
})
'';

This is (finally !) addressed by #1174 :)
