## Vim bindings demo

#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:

The vim keybindings are enabled by including keymap/vim.js and setting the `vimMode` option to `true`. This will also automatically change the `keyMap` option to `"vim"`.

Features

- All common motions and operators, including text objects
- Operator motion orthogonality
- Visual mode - characterwise, linewise, partial support for 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

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
