VimSuggest: Supercharge Your Vim Command-Line

The ultimate auto-completion plugin for Vim command-line.

🚀 Enhance Vim Workflow

• Command Completion: Never struggle to remember complex commands again.
• Search Suggestions: Access relevant search terms with fewer keystrokes, enhancing your navigation.

🌟 Additional Features

VimSuggest goes beyond basic auto-completion, offering a suite of advanced features by leveraging Vim's native custom completion mechanism (:h :command-completion-custom). These features feel like a natural extension of the editor, but they can be easily disabled if desired.

• Asynchronous Fuzzy File Search (:VSFind): Effortlessly locate files across your entire project with minimal keystrokes.
• Real-Time Live Grep (:VSGrep): Instantly find text across your entire codebase using glob or regex patterns.
• Fuzzy Search: Quickly locate buffers (:VSBuffer) and search various Vim artifacts.
• In-Buffer Search (:VSGlobal): Leverage Vim's powerful :global command for lightning-fast buffer searches.
• Include File Search (:VSInclSearch): Seamlessly search across included files using Vim's :ilist command.
• Live File Search (:VSFindL): Asynchronously search for files using glob or regex patterns.
• Custom Shell Command Execution (:VSExec): Run and interact with shell commands directly within Vim.

Auto-completion can also be disabled by default and only triggered when the <Tab> key is pressed, which more closely aligns with Vim's default behavior.

Requirements

• Vim version 9.1 or higher

Installation

Install VimSuggest via vim-plug or Vim's built-in package manager.

Using vim-plug

Add the following to your .vimrc:

call plug#begin()
Plug 'girishji/vimsuggest'
call plug#end()

Using Vim's built-in package manager

Linux

git clone https://github.com/girishji/vimsuggest.git $HOME/.vim/pack/downloads/opt/vimsuggest

Then add this line to your vimrc file:

packadd vimsuggest

Windows

git clone https://github.com/girishji/vimsuggest.git %USERPROFILE%\vimfiles\pack\downloads\opt\vimsuggest

Then add this line to your vimrc file:

packadd vimsuggest

Configuration Guide

VimSuggest offers extensive customization options for both command completion and search completion.

Command Completion Configuration

let s:vim_suggest = {}
let s:vim_suggest.cmd = {
    \ 'enable': v:true,
    \ 'pum': v:true,
    \ 'exclude': [],
    \ 'onspace': ['b\%[uffer]','colo\%[rscheme]'],
    \ 'alwayson': v:true,
    \ 'popupattrs': {},
    \ 'wildignore': v:true,
    \ 'addons': v:true,
    \ 'ctrl_np': v:false,
    \ 'reverse': v:false,
\ }

[!NOTE] Typing <Tab> bypasses the exclude list and opens the completion menu.

Search Completion Configuration

let s:vim_suggest.search = {
    \ 'enable': v:true,
    \ 'pum': v:true,
    \ 'fuzzy': v:false,
    \ 'alwayson': v:true,
    \ 'popupattrs': {
    \   'maxheight': 12
    \ },
    \ 'range': 100,
    \ 'timeout': 200,
    \ 'async': v:true,
    \ 'async_timeout': 3000,
    \ 'async_minlines': 1000,
    \ 'highlight': v:true,
    \ 'ctrl_np': v:false,
\ }

[!IMPORTANT]

1. Searching large files will not cause any lag. By default, searching is concurrent. Even though no external jobs are used, a timer pauses the task at regular intervals to check if there are pending keys on the typehead.
2. When searching across line boundaries (\n), search highlighting will be turned off.

Applying Configuration

To apply your configuration:

call g:VimSuggestSetOptions(s:vim_suggest)

If you are using vim-plug you may have to do:

autocmd VimEnter * call g:VimSuggestSetOptions(s:vim_suggest)

Global Enable/Disable

Enable or disable VimSuggest globally:

:VimSuggestEnable   " Enable VimSuggest
:VimSuggestDisable  " Disable VimSuggest

Highlighting

VimSuggest uses custom highlight groups:

• VimSuggestMatch: Highlights matched portion of the text. Linked to PmenuMatch by default.
• VimSuggestMatchSel: Highlights matched text in the selected item of the menu. Linked to PmenuMatchSel by default.
• VimSuggestMute: Highlights passive text like line numbers in grep output. Linked to LineNr by default.

Customization Examples

" Customize popup window appearance
let s:vim_suggest.cmd.popupattrs = {
    \ 'borderchars': ['─', '│', '─', '│', '┌', '┐', '┘', '└'],
    \ 'borderhighlight': ['Normal'],
    \ 'highlight': 'Normal',
    \ 'border': [1, 1, 1, 1],
    \ 'maxheight': 20,
    \ }

" Exclude specific patterns from completion
"   To exclude :[N]b[uffer][!] and :[N]sb[uffer][!] do:
let s:vim_suggest.cmd.exclude = [
    \ '^\s*\d*\s*b\%[uffer]!\?\s\+',
    \ '^\s*\d*\s*sb\%[uffer]!\?\s\+'
    \ ]

" Apply the configuration
call g:VimSuggestSetOptions(s:vim_suggest)

" Customize highlight groups
highlight VimSuggestMatch ctermfg=Green guifg=#00FF00
highlight VimSuggestMatchSel cterm=bold gui=bold ctermfg=Green guifg=#00FF00
highlight VimSuggestMute ctermfg=Gray guifg=#808080

Key Bindings

When the popup window is open, you can use the following key mappings:

Note: Keys used in command-line editing (:h cmdline-editing) remain unmodified.

[!TIP]

1. If no item is selected, pressing <Enter> selects the first menu item (works only for 'addons' commands).
2. To automatically open the quickfix list after using <Ctrl-q>, add the following to your .vimrc:

   augroup vimsuggest-qf-show
       autocmd!
       autocmd QuickFixCmdPost clist cwindow
   augroup END
   

3. To perform a multi-word search using the / or ? command, type the first word followed by <Space> to trigger auto-completion for the next word. At the end of a line, press \n to continue the search on the next line. Note that enabling the fuzzy search option will disable multi-word search functionality.
4. When completing files during :edit command, <Tab> selects subsequent items in the menu. In order to step into a directory select the directory and press /; it will populate items from that directory.

Addons

When the addons option is set to v:true, the following commands are made available. You can use these commands directly or map them to your preferred keys.

1. Fuzzy Find Files

   :VSFind [dirpath] [fuzzy_pattern]

   This runs the system's find program (or alternatives) asynchronously to gather files for fuzzy searching. The optional first argument is the directory to search within.

   Example key mappings:

   nnoremap <key> :VSFind<space>
   nnoremap <key> :VSFind ~/.vim<space>
   nnoremap <key> :VSFind $VIMRUNTIME<space>
   

   The 'find' program can be specified through the g:vimsuggest_fzfindprg variable. If this variable is not defined, a default command is used (that ignores hidden files and directories). The placeholder "$*" is allowed to specify where the optional directory argument will be included. If placeholder is not specifed, directory name is included at the end. Environment variables and tilde are expanded for directory names.

   let g:vimsuggest_fzfindprg = 'find $* \! \( -path "*/.*" -prune \) -type f -follow'
   let g:vimsuggest_fzfindprg = 'fd --type f .'
   

   (Optional) To execute the program through a shell:

   let g:vimsuggest_shell = true
   set shell=/bin/sh
   set shellcmdflag=-c
   

   Performance:

   Using the system's find program significantly outperforms Vim's :find command. On the Vim source repository, it takes ~1 second to list all files using :find **/* command, while :VSFind takes ~30 milliseconds (30x faster). Shell's recursive glob wildcard can be slow.

2. Fuzzy Search Buffers and Other Vim Artifacts

   :VSBuffer [fuzzy_pattern]
   :VSGitFind [dir] [fuzzy_pattern]
   :VSMru [fuzzy_pattern]
   :VSKeymap [fuzzy_pattern]
   :VSMark [fuzzy_pattern]
   :VSRegister [fuzzy_pattern]
   :VSChangelist [fuzzy_pattern]
   

   • VSBuffer: Search and switch between currently open buffers
     • Displays matching buffers as you type
   • VSGitFind: Smart file search with Git awareness
     • In Git repositories: Searches tracked files
     • Outside Git (or if 'dir' is given): Falls back to regular file search (like VSFind)
   • VSMru: Access recently used files
     • Lists files from Vim's v:oldfiles history
     • Example: Quickly return to files you edited yesterday
   • VSKeymap: Navigate to keymap definitions
     • Opens the source file containing the definition of keymap
   • VSMark: Quick mark navigation
     • Jump to any mark location in your files
   • VSRegister: Register content access
     • Paste the content of register
   • VSChangelist: Navigate through changes
     • Jump to any point in the file's change history
     • See :help changelist for details

   Example key mapping:

   nnoremap <key> :VSBuffer<space>
   

3. Live Grep Search

   :VSGrep {pattern} [directory]

   Executes a grep command live, showing results as you type. {pattern} is given directly to grep command, and it's best to enclose it in quotes to handle special characters. You can also specify an optional directory.

   Example key mappings:

   nnoremap <key> :VSGrep ""<left>
   nnoremap <key> :VSGrep "<c-r>=expand('<cword>')<cr>"<left>
   

   The grep program is taken from g:vimsuggest_grepprg variable or the :h 'grepprg' option. If it contains $*, it gets replaced by the command-line arguments. Otherwise, arguments are appended to the end of the command.

   let g:vimsuggest_grepprg = 'grep -REIHins $* --exclude-dir=.git --exclude=".*"'
   let g:vimsuggest_grepprg = 'rg --vimgrep --smart-case $* .'
   let g:vimsuggest_grepprg = 'ag --vimgrep'
   

4. Live File Search

   :VSFindL {pattern} [directory]

   This command runs system's find program live, showing results as you type. {pattern} is a glob (or regex) pattern that should be enclosed in quotes if it contains wildcards. The find command is customized via g:vimsuggest_findprg (similar to g:vimsuggest_fzfindprg).

   Example key mapping and configuring 'find' program:

   nnoremap <key> :VSFindL "*"<left><left>
   let g:vimsuggest_findprg = 'find -EL $* \! \( -regex ".*\.(swp\|git)" -prune \) -type f -name $*'
   " Using fd:
   nnoremap <key> :VSFindL<space>
   let g:vimsuggest_findprg = 'fd --type f'
   let g:vimsuggest_findprg = 'fd --type f --glob'
   

5. In-Buffer Search (:h :global)

   :VSGlobal {regex_pattern}

   Use this for a powerful in-buffer search with Vim's regex. For example, to list all functions and classes in a Python file and jump quickly:

   nnoremap <buffer> <key> :VSGlobal \v(^\|\s)(def\|class).{-}
   

6. Search in Included Files (:h include-search)

   :VSInclSearch {regex_pattern}

   Similar to VSGlobal, but searches for symbols (ignoring comments) in both the current buffer and included files. The results are gathered using the :ilist command.

   Example key mapping:

   nnoremap <key> :VSInclSearch<space>
   

7. Execute Shell Command

   :VSExec {shell_command}

   This command runs any shell command using your $SHELL environment, allowing features like brace expansion and globbing. Errors are ignored. However, :VSGrep and VSFindL commands are less clunky.

   Example key mappings:

   nnoremap <key> :VSExec fd --type f<space>
   nnoremap <key> :VSExec grep -RIHins "" . --exclude-dir={.git,"node_*"} --exclude=".*"<c-left><c-left><c-left><left><left>
   " Easier to type but low performance:
   nnoremap <key> :VSExec grep -IHins "" **/*<c-left><left><left>
   

[!IMPORTANT] External programs are executed directly if g:vimsuggest_shell is v:false. Otherwise, they are executed through shell as specified in shell option (:h 'shell'). Using shell allows for expansion of ~, $VAR, ** (if your shell supports), etc.

let g:vimsuggest_shell = v:true
set shell=/bin/zsh
set shellcmdflag=-c

See also :h expandcmd()

[!TIP] If these commands aren't sufficient, you can define your own using the examples provided in autoload/vimsuggest/addons/addons.vim script. Legacy script users can import using :import also (see :h import-legacy).
