## About
|
|
[There](https://github.com/paradigm/vim-multicursor) [have](https://github.com/felixr/vim-multiedit) [been](https://github.com/hlissner/vim-multiedit) [many](https://github.com/adinapoli/vim-markmultiple) [attempts](https://github.com/AndrewRadev/multichange.vim) at bringing Sublime Text's awesome [multiple selection][sublime-multiple-selection] feature into Vim, but none so far have been in my opinion a faithful port that is simplistic to use, yet powerful and intuitive enough for an existing Vim user. [vim-multiple-cursors] is yet another attempt at that.
|
|
|
|
### It's great for quick refactoring
|
|
|
|
|
|
Vim command sequence: `fp<C-n><C-n><C-n>cname`
|
|
|
|
### Add a cursor to each line of your visual selection
|
|
|
|
|
|
Vim command sequence: `vip<C-n>i"<Right><Right><Right>",<Esc>vipgJ$r]Idays = [`
|
|
|
|
### Match characters from visual selection
|
|
|
|
|
|
Vim command sequence: `df[$r,0f,v<C-n>…<C-n>c<CR><Up><Del><Right><Right><Right><Del>`
|
|
|
|
### Use the command to match regexp
|
|
|
|
|
|
To see what keystrokes are used for the above examples, see [the wiki page](https://github.com/terryma/vim-multiple-cursors/wiki/Keystrokes-for-example-gifs).
|
|
|
|
## Installation
|
|
Install using [Pathogen], [Vundle], [Neobundle], [vim-plug], or your favorite Vim package manager.
|
|
|
|
Requires vim 7.4 or newer for full functionality.
|
|
|
|
### vim-plug instructions
|
|
|
|
1. Paste this block into the top of `~/.vimrc`.
|
|
|
|
```vim script
|
|
call plug#begin()
|
|
|
|
Plug 'terryma/vim-multiple-cursors'
|
|
|
|
call plug#end()
|
|
```
|
|
|
|
2. Start vim and execute `:PlugInstall`.
|
|
|
|
## Quick Start
|
|
### normal mode / visual mode
|
|
* start: `<C-n>` start multicursor and add a _virtual cursor + selection_ on the match
|
|
* next: `<C-n>` add a new _virtual cursor + selection_ on the next match
|
|
* skip: `<C-x>` skip the next match
|
|
* prev: `<C-p>` remove current _virtual cursor + selection_ and go back on previous match
|
|
* select all: `<A-n>` start multicursor and directly select all matches
|
|
|
|
You can now change the _virtual cursors + selection_ with **visual mode** commands.
|
|
For instance: `c`, `s`, `I`, `A` work without any issues.
|
|
You could also go to **normal mode** by pressing `v` and use normal commands there.
|
|
|
|
At any time, you can press `<Esc>` to exit back to regular Vim.
|
|
|
|
**NOTE**: start with `g<C-n>` to match without boundaries (behaves like `g*` instead of `*`)
|
|
|
|
### visual mode when multiple lines are selected
|
|
* start: `<C-n>` add _virtual cursors_ on each line
|
|
|
|
You can now change the _virtual cursors_ with **normal mode** commands.
|
|
For instance: `ciw`.
|
|
|
|
### command
|
|
The command `MultipleCursorsFind` accepts a range and a pattern (regexp), it creates a _visual cursor_ at the end of each match.
|
|
If no range is passed in, then it defaults to the entire buffer.
|
|
|
|
|
|
## Mapping
|
|
If you don't like the plugin taking over your key bindings, you can turn it off and reassign them the way you want:
|
|
```viml
|
|
let g:multi_cursor_use_default_mapping=0
|
|
|
|
" Default mapping
|
|
let g:multi_cursor_start_word_key = '<C-n>'
|
|
let g:multi_cursor_select_all_word_key = '<A-n>'
|
|
let g:multi_cursor_start_key = 'g<C-n>'
|
|
let g:multi_cursor_select_all_key = 'g<A-n>'
|
|
let g:multi_cursor_next_key = '<C-n>'
|
|
let g:multi_cursor_prev_key = '<C-p>'
|
|
let g:multi_cursor_skip_key = '<C-x>'
|
|
let g:multi_cursor_quit_key = '<Esc>'
|
|
```
|
|
|
|
**NOTE:** Please make sure to always map something to `g:multi_cursor_quit_key`, otherwise you'll have a tough time quitting from multicursor mode.
|
|
|
|
## Settings
|
|
Currently there are four additional global settings one can tweak:
|
|
|
|
### ```g:multi_cursor_support_imap``` (Default: 1)
|
|
If set to 0, insert mappings won't be supported in _Insert_ mode anymore.
|
|
|
|
### ```g:multi_cursor_exit_from_visual_mode``` (Default: 0)
|
|
If set to 1, then pressing `g:multi_cursor_quit_key` in _Visual_ mode will quit and
|
|
delete all existing cursors, just skipping normal mode with multiple cursors.
|
|
|
|
### ```g:multi_cursor_exit_from_insert_mode``` (Default: 0)
|
|
If set to 1, then pressing `g:multi_cursor_quit_key` in _Insert_ mode will quit and
|
|
delete all existing cursors, just skipping normal mode with multiple cursors.
|
|
|
|
### ```g:multi_cursor_normal_maps``` (Default: see below)
|
|
`{'@': 1, 'F': 1, 'T': 1, '[': 1, '\': 1, ']': 1, '!': 1, '"': 1, 'c': 1, 'd': 1, 'f': 1, 'g': 1, 'm': 1, 'q': 1, 'r': 1, 't': 1, 'y': 1, 'z': 1, '<': 1, '=': 1, '>': 1}`
|
|
|
|
Any key in this map (values are ignored) will cause multi-cursor _Normal_ mode
|
|
to pause for map completion just like normal vim. Otherwise keys mapped in
|
|
normal mode will "fail to replay" when multiple cursors are active.
|
|
For example: `{'d':1}` makes normal-mode command `dw` work in multi-cursor mode.
|
|
|
|
The default list contents should work for anybody, unless they have remapped a
|
|
key from an operator-pending command to a non-operator-pending command or
|
|
vice versa.
|
|
|
|
These keys must be manually listed because vim doesn't provide a way to
|
|
automatically see which keys _start_ mappings, and trying to run motion commands
|
|
such as `j` as if they were operator-pending commands can break things.
|
|
|
|
### ```g:multi_cursor_visual_maps``` (Default: see below)
|
|
`{'T': 1, 'a': 1, 't': 1, 'F': 1, 'f': 1, 'i': 1}`
|
|
|
|
Same principle as `g:multi_cursor_normal_maps`
|
|
|
|
### Interactions with other plugins
|
|
|
|
### ```Multiple_cursors_before/Multiple_cursors_after``` (Default: `nothing`)
|
|
|
|
Other plugins may be incompatible in insert mode.
|
|
That is why we provide hooks to disable those plug-ins when vim-multiple-cursors is active:
|
|
|
|
For example, if you are using [Neocomplete](https://github.com/Shougo/neocomplete.vim),
|
|
add this to your vimrc to prevent conflict:
|
|
|
|
```viml
|
|
function! Multiple_cursors_before()
|
|
if exists(':NeoCompleteLock')==2
|
|
exe 'NeoCompleteLock'
|
|
endif
|
|
endfunction
|
|
|
|
function! Multiple_cursors_after()
|
|
if exists(':NeoCompleteUnlock')==2
|
|
exe 'NeoCompleteUnlock'
|
|
endif
|
|
endfunction
|
|
```
|
|
|
|
Plugins themselves can register `User` autocommands on `MultipleCursorsPre` and
|
|
`MultipleCursorsPost` for automatic integration.
|
|
|
|
### Highlight
|
|
The plugin uses the highlight group `multiple_cursors_cursor` and `multiple_cursors_visual` to highlight the virtual cursors and their visual selections respectively. You can customize them by putting something similar like the following in your vimrc:
|
|
|
|
```viml
|
|
" Default highlighting (see help :highlight and help :highlight-link)
|
|
highlight multiple_cursors_cursor term=reverse cterm=reverse gui=reverse
|
|
highlight link multiple_cursors_visual Visual
|
|
```
|
|
|
|
## FAQ
|
|
|
|
#### **Q** Pressing <kbd>i</kbd> after selecting words with <kbd>C-n</kbd> makes the plugin hang, why?
|
|
**A** When selecting words with <kbd>C-n</kbd>, the plugin behaves like in **visual** mode.
|
|
Once you pressed <kbd>i</kbd>, you can still press <kbd>I</kbd> to insert text.
|
|
|
|
#### **Q** <kbd>ALT</kbd>+<kbd>n</kbd> doesn't seem to work in VIM but works in gVIM, why?
|
|
**A** This is a well known terminal/Vim [issue](http://vim.wikia.com/wiki/Get_Alt_key_to_work_in_terminal), different terminal have different ways to send ```Alt+key```.
|
|
Try adding this in your `.vimrc` and **make sure to replace the string**:
|
|
```vim
|
|
if !has('gui_running')
|
|
map "in Insert mode, type Ctrl+v Alt+n here" <A-n>
|
|
endif
|
|
```
|
|
Or remap the following:
|
|
```vim
|
|
g:multi_cursor_start_key
|
|
g:multi_cursor_select_all_key
|
|
```
|
|
|
|
#### **Q** <kbd>CTRL</kbd>+<kbd>n</kbd> doesn't seem to work in gVIM?
|
|
**A** Try setting `set selection=inclusive` in your `~/.gvimrc`
|
|
|
|
**A** Alternatively, you can just temporarily disable _exclusive_ selection whenever the plugin is active:
|
|
```VimL
|
|
augroup MultipleCursorsSelectionFix
|
|
autocmd User MultipleCursorsPre if &selection ==# 'exclusive' | let g:multi_cursor_save_selection = &selection | set selection=inclusive | endif
|
|
autocmd User MultipleCursorsPost if exists('g:multi_cursor_save_selection') | let &selection = g:multi_cursor_save_selection | unlet g:multi_cursor_save_selection | endif
|
|
augroup END
|
|
```
|
|
|
|
### **Q** deoplete insert giberrish, how to fix this?
|
|
**A** use the `Multiple_cursors` functions, add this in your vimrc:
|
|
|
|
```VimL
|
|
func! Multiple_cursors_before()
|
|
if deoplete#is_enabled()
|
|
call deoplete#disable()
|
|
let g:deoplete_is_enable_before_multi_cursors = 1
|
|
else
|
|
let g:deoplete_is_enable_before_multi_cursors = 0
|
|
endif
|
|
endfunc
|
|
func! Multiple_cursors_after()
|
|
if g:deoplete_is_enable_before_multi_cursors
|
|
call deoplete#enable()
|
|
endif
|
|
endfunc
|
|
```
|
|
|
|
#### **Q** is it also working on Mac?
|
|
**A** On Mac OS, [MacVim](https://code.google.com/p/macvim/) is known to work.
|
|
|
|
#### **Q** How can I select `n` keywords with several keystrokes? `200<C-n>` does not work.
|
|
**A** You can use :MultipleCursorsFind keyword. I have this binding in my vimrc:
|
|
|
|
```VimL
|
|
nnoremap <silent> <M-j> :MultipleCursorsFind <C-R>/<CR>
|
|
vnoremap <silent> <M-j> :MultipleCursorsFind <C-R>/<CR>
|
|
```
|
|
|
|
This allows one to search for the keyword using `*` and turn search results into cursors with `Alt-j`.
