Command mode configuration, accept shorthand suggestions

[russell-knight]

The main two commands I use are :w and :q. With blink autocomplete enabled for the command line when I type either of these I get a list of suggestions that includes the longform version of these commands e.g write present in the image below

I can see that wq is also present in the list so perhaps there is a limit on command length imposed somewhere? I've tried adding a min_keyword_length = 1 to opts.sources.

Is it possible to expose these shorthand commands I use in the autocomplete list? Or alternatively, is it possible to show the autocomplete list without highlighting the first option, so that by typing :w<CR> I can save my file as usual?

You can make it not select by default in cmdline on v0.8.2 like https://cmp.saghen.dev/configuration/completion.html#list

The list itself comes from the built in completions so I'm not sure about adding shorthands, although I imagine it wouldn't be particularly useful to have single character options

This works perfectly thank you!

I have noticed that using the suggested

completion.list.selection = function(ctx)
  return ctx.mode == 'cmdline' and 'auto_insert' or 'preselect'
end

requires to press the accept twice for the command to be accepted in the commandline. In the recording below you can see that after selecting an entry (help) the first keypress only "closes" the completion window, whereas the second runs the command: is this intended behaviour?

My keymaps configuration is as follows:

keymap = {
	["<CR>"] = { "accept", "fallback" },
	["<Tab>"] = { "select_next", "fallback" },
	["<S-Tab>"] = { "select_prev", "fallback" },
	["<C-k>"] = { "scroll_documentation_up", "fallback" },
	["<C-j>"] = { "scroll_documentation_down", "fallback" },
	["<C-e>"] = { "hide" },
	["K"] = { "show", "show_documentation", "hide_documentation" },
}

and the same occurs where one uses accept or select_and_accept.

I'm not the maintainer, but I was looking for a solution to exactly what you are describing, and there was a note somewhere in the docs that says you can provide a callback to accept:

            keymap = {
                cmdline = {
                    ['<cr>'] = {
                        function(cmp)
                            -- Enter should accept and execute (instead of just accept)
                            -- This lets me press enter once to execute a :cmdline command, instead of pressing twice
                            return cmp.accept({ callback = function() vim.api.nvim_feedkeys('\n', 'n', true) end })
                        end, "fallback"
                    },
                    ['<Tab>'] = { 'select_next' }
                },
         }

The tab binding is unrelated, I'm just leaving that in there because using keymap.cmdline removes all the default cmdline mappings, so you don't have a way to select the completions.

Thank you, I had missed such instruction, it works as intended indeed!
