# Using FakeVim Mode

In the FakeVim mode, you can run the main editor in a manner similar to the Vim editor. To run the editor in the FakeVim mode, select Edit > Advanced > Use Vim-style Editing or press Alt+V,Alt+V.

## Supported Modes and Commands

In the FakeVim mode, most keystrokes in the main editor will be intercepted and interpreted in a way that resembles Vim. Most of the supported commands can be followed by a motion command or executed in visual mode, or they work with registers or can be prefixed with a number of repetitions.

The following sections describe the commands emulated in the supported modes and how they diverge from Vim in functionality:

- Normal
- Visual
- Command line (:)
- Insert and replace

For more information on using Vim, see Documentation on the Vim web site.

### Normal and Visual Modes

- Basic movement, such as `h/j/k/l`, `<C-U>`, `<C-D>`, `<C-F>`, `<C-B>`, `gg`, `G`, `0`, `^`, `$`
- Word movement, such as `w`, `e`, `b`
- Inner/a movement, such as `ciw`, `3daw`, ya{
- `f` and `t` movement
- `[ and \c ]` movement
- { and } paragraph movement
- Delete/change/yank/paste with register
- Undo and redo
- `<C-A>` and `<C-X>` increase or decrease a number in decimal, octal, or hexadecimal format (for example `128<C-A>` on or before `"0x0ff"` changes it to `"0x17f"`)
- `.` repeats the last change
- `/search`, `?search`, `*`, `#`, `n`, `N` - most of regular expression syntax is used in Vim except that `\<` and `\>` are the same as `\b` in QRegExp
- `@` and `q` (macro recording and execution) special keys are saved as `<S-Left>`
- Marks
- `gv` goes to last visual selection; can differ if text is edited around it
- Indentation using `=`, `<<`, `>>`, with movement, count, and in visual mode
- to upper/lower, such as `~`, `gU`, `gu`
- `i`, `a`, `o`, `I`, `A`, and `O` enter insert mode
- Scroll window, such as `zt`, `zb`, `zz`
- Wrap line movement, such as `gj`, `gk`, `g0`, `g^`, `g$`

### Command Line Mode

- `:map`, `:unmap`, `:inoremap`, and so on
- `:source` provides very basic line-by-line sourcing of vimrc files
- `:substitute` substitutes an expression in a range
- `:'<,'>!cmd` filters through an external command (for example, sorts the lines in a file with `:%!sort`)
- `:<range>sor[t][!]`
- `:.!cmd` inserts the standard output of an external command
- `:read`
- `:yank`, `:delete`, `:change`
- `:move`, `:join`
- `:20` goes to an address
- `:history`
- `:registers`, `:display`
- `:nohlsearch`
- `:undo`, `:redo`
- `:normal`
- `:<`, `:>`
- `set formatoptions=`, see `:h fo-table` in the Vim documentation. Currently supported letters: `fo-j`

### Plugin Emulation

FakeVim also emulates some popular vim plugins. To enable plugin emulation for particular plugins, select Tools > Options > FakeVim > General > Plugin Emulation.

Currently emulated plugins:

- vim-commentary: `gc` action to comment code regions. For example, `gcc`, `gc2j`, `gcip`
- ReplaceWithRegister:
  - `[count]["x]gr{motion}` to replace `motion` with the contents of register `x`.
  - ["x]grr to replace the current line.
- vim-exchange
- argtextobj.vim: Defines the `ia` and `aa` text objects for function parameters.
- vim-surround: Adds mappings for deleting, adding and changing surroundings.

### Insert Mode

- `<C-O>` executes a single command and returns to insert mode
- `<C-V>` inserts a raw character
- `<insert>` toggles replace mode

### Options

Use `:set ...` to set the options listed in the following table:

Long Name | Short Name | Arguments
--- | --- | ---
`autoindent` | `ai` |
`backspace` | `bs` | `indent`, `eol`, `start`
`blinkingcursor` | `bc` |
`clipboard` | `cb` |
`expandtab` | `et` |
`hlsearch` | `hls` |
`ignorecase` | `ic` |
`incsearch` | `is` |
`iskeyword` | `isk` | A combination of the following characters: `@`, `48-57`, `_`, `192-255`, `a-z`, `A-Z`
`relativenumber` | `rnu` |
`scrolloff` | `so` |
`shiftwidth` | `sw` |
`showcmd` | `sc` |
`smartcase` | `scs` |
`smartindent` | `si` |
`smarttab` | `sta` |
`startofline` | `sol` |
`tabstop` | `ts` |
`tildeop` | `top` |
`usecoresearch` | `ucs` |
`wrapscan` | `ws` |

### Vimrc Example

     " highlight matched
     set hlsearch
     " case insensitive search
     set ignorecase
     set smartcase
     " search while typing
     set incsearch
     " wrap-around when searching
     set wrapscan
     " show pressed keys in lower right corner
     set showcmd
     " tab -> spaces
     set expandtab
     set tabstop=4
     set shiftwidth=4
     " keep a 5 line buffer for the cursor from top/bottom of window
     set scrolloff=5
     " X11 clipboard
     set clipboard=unnamed
     " use ~ with movement
     set tildeop

     " mappings
     nnoremap ; :
     inoremap jj <Esc>

     " clear highlighted search term on space
     noremap <silent> <Space> :nohls<CR>

     " reselect visual block after indent
     vnoremap < <gv
     vnoremap > >gv

     " MOVE LINE/BLOCK
     nnoremap <C-S-J> :m+<CR>==
     nnoremap <C-S-K> :m-2<CR>==
     inoremap <C-S-J> <Esc>:m+<CR>==gi
     inoremap <C-S-K> <Esc>:m-2<CR>==gi
     vnoremap <C-S-J> :m'>+<CR>gv=gv
     vnoremap <C-S-K> :m-2<CR>gv=gv

## Mapping FakeVim Commands

To map commands entered on the FakeVim command line to actions of the Qt Creator core, select Tools > Options > FakeVim > Ex Command Mapping.

To map user commands to keyboard shortcuts, select Tools > Options > FakeVim > User Command Mapping. The user command mapped to the shortcut is executed by FakeVim as if you were typing it (as when replaying a macro).

## Specifying FakeVim Options

To make changes to the Vim-style settings, select Tools > Options > FakeVim > General.

To preselect the indentation settings specified for the text editor, select Copy Text Editor Settings. To preselect the Qt coding style, select Set Qt Style. To preselect a simple indentation style, select Set Plain Style. You can then change any of the preselected settings.

To use a Vim-style color scheme, select Tools > Options > Text Editor > Fonts & Color. In the Color Scheme list, select Vim (dark).

## Quitting FakeVim Mode

To quit the FakeVim mode, unselect Tools > Options > FakeVim > Use FakeVim or press Alt+V,Alt+V.

You can temporarily escape FakeVim mode to access the normal Qt Creator keyboard shortcuts like Ctrl-R for Run by pressing , first.
