Autocomplete Plugin for Vim's Cmdline Mode (Needs Vim >= 9.0)

Wouldn't it be nice to have autocomplete during search and command execution? This unobtrusive plugin simply opens a popup menu and shows autocompletion options when you search (/, ?) or enter commands (:) in commandline-mode.

How it helps?

  • Preview searchable words and commands (and their arguments).
  • Search multiple words, even across line boundary; Fuzzy search.
  • All Vim idioms work as before. No surprises.
  • Fast, does not hang up when searching large files or expanding wildcards.

How to use it?

  • Search using / or ? or enter commands using : as usual.
  • <Tab> and <Shift-tab> will select menu items.
  • <Ctrl-E> dismisses popup menu.
  • <Enter> accepts selection, and <Esc> dismisses search.
  • <Ctrl-C> will force popup menu to close.

Multiword Search

  • Type the character between words (like <Space>) after the first word to include the second word in search.
  • Type \n at the end of the last word in a line to continue to next line.
  • Available only when fuzzy option is not selected.

For insert-mode autocompletion see Vimcomplete.

Features

  • Does not interfere with [c|d|y]/{pattern} commands (copy/delete/yank).
  • Respects forward (/) and reverse (?) search when displaying menu items.
  • Does not interfere with search-highlighting and incremental-search.
  • Does not interfere with search-history recall (arrow keys, <Ctrl-N/P> are not mapped).
  • Fuzzy search option.
  • Will not hang under any circumstance (including ** wildcards)
  • Command names, arguments, Vimscript functions, variables, etc., are autocompleted.
  • Switch between normal popup menu and flat menu.
  • Written in Vim9script for readability and ease of maintenance (and speed).

Requirements

  • Vim >= 9.0

Installation

Install using vim-plug

vim9script
plug#begin()
Plug 'girishji/autosuggest.vim'
plug#end()

Legacy script:

call plug#begin()
Plug 'girishji/autosuggest.vim'
call plug#end()

Or use Vim's builtin package manager.

Configuration

Options

Default options are as follows.

vim9script
var options = {
    search: {
        enable: true,   # 'false' will disable search completion
        maxheight: 12,	# line count of stacked menu
        pum: true,	    # 'false' for flat menu, 'true' for stacked menu
        fuzzy: false,   # fuzzy completion
        alwayson: true, # when 'false' press <tab> to open popup menu
        hidestatusline: false, # (experimental) hide statusline when 'pum' is 'false'
    },
    cmd: {
        enable: true,   # 'false' will disable command completion
        pum: true,      # 'false' for flat menu, 'true' for stacked menu
        fuzzy: false,   # fuzzy completion
        hidestatusline: false, # (experimental) hide statusline when 'pum' is 'false'
    }
}

Options can be modified using g:AutoSuggestSetup(). If you are using vim-plug use the VimEnter event as follows.

autocmd VimEnter * g:AutoSuggestSetup(options)

Commands

Enable and disable this plugin

  • :AutoSuggestEnable
  • :AutoSuggestDisable

Highlight Groups

Highlight group AS_SearchCompletePrefix affects style of the fragment of menu item that matches text being searched. By default it is linked to highlight group Special. Popup menu appearance is determined by Vim's highlight groups Pmenu, PmenuSel, PmenuSbar and PmenuThumb. For command completion WildMenu group (:h hl-WildMenu) can be used.

Case Sensitive Search

Set ignorecase and smartcase using set command. See :h 'ignorecase' and h 'smartcase'.

Performance

Care is taken to ensure that responsiveness does not deteriorate when searching large files or expanding wildcards. Large files are searched in batches. Between each search attempt input keystrokes are allowed to be queued into Vim's main loop. Wildcard expansions are first executed in a separate job and aborted after a timeout.
