# 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`
- `:<`, `:>`

### 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 following options:

- `autoindent`
- `clipboard`
- `backspace`
- `expandtab`
- `hlsearch`
- `ignorecase`
- `incsearch`
- `indent`
- `iskeyword`
- `scrolloff`
- `shiftwidth`
- `showcmd`
- `smartcase`
- `smartindent`
- `smarttab`
- `startofline`
- `tabstop`
- `tildeop`
- `wrapscan`

### 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.
