<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 */

|
<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>
