<h2>Vim bindings demo</h2>

<p><strong style="color: #c33; text-decoration: none">Note:</strong>
The CodeMirror vim bindings are maintained in
the <a href="https://github.com/replit/codemirror-vim">codemirror-vim</a>
repository, not this project. The file is still included in the
distribution for backwards compatibility.</p>

<form><textarea id="code" name="code">
#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;
}
</textarea></form>
<div style="font-size: 13px; width: 300px; height: 30px;">Key buffer: <span id="command-display"></span></div>
<div style="font-size: 13px; width: 300px; height: 30px;">Vim mode: <span id="vim-mode"></span></div>

<p>The vim keybindings are enabled by including <code><a
href="../keymap/vim.js">keymap/vim.js</a></code> and setting the
<code>keyMap</code> option to <code>vim</code>.</p>

<p><strong>Features</strong></p>

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

<p>For the full list of key mappings and Ex commands, refer to the
<code>defaultKeymap</code> and <code>defaultExCommandMap</code> at the
top of <code><a href="../keymap/vim.js">keymap/vim.js</a></code>.

<p>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</p>
