## Vim bindings demo

Note: The CodeMirror vim bindings are maintained in the codemirror-vim repository, not this project. The file is still included in the distribution for backwards compatibility.

#include "syscalls.h" /* getchar: simple buffered version */ int getchar(void) { static char buf[BUFSIZ]; static char *bufp = buf; static int n = 0; if (n == 0) { /* buffer is empty */ n = read(0, buf, sizeof buf); bufp = buf; } return (--n >= 0) ? (unsigned char) *bufp++ : EOF; }
Key buffer:
Vim mode:

The vim keybindings are enabled by including `keymap/vim.js` and setting the `keyMap` option to `vim`.

Features

- All common motions and operators, including text objects
- Operator motion orthogonality
- Visual mode - characterwise, linewise, blockwise
- Full macro support (q, @)
- Incremental highlighted search (/, ?, #, *, g#, g*)
- Search/replace with confirm (:substitute, :%s)
- Search history
- Jump lists (Ctrl-o, Ctrl-i)
- Key/command mapping with API (:map, :nmap, :vmap)
- Sort (:sort)
- Marks (`, ')
- :global
- Insert mode behaves identical to base CodeMirror
- Cross-buffer yank/paste

For the full list of key mappings and Ex commands, refer to the `defaultKeymap` and `defaultExCommandMap` at the top of `keymap/vim.js`.

Note that while the vim mode tries to emulate the most useful features of vim as faithfully as possible, it does not strive to become a complete vim implementation
