<h2>Vim bindings demo</h2> |
|
|
|
<p><strong style="color: #c33; text-decoration: none">Note:</strong> The CodeMirror vim bindings do not have an |
|
active maintainer. That means that if you report bugs in it, they are |
|
likely to go unanswered. It also means that if you want to help, you |
|
are very welcome to look |
|
at <a href="https://github.com/codemirror/codemirror/issues?q=is%3Aissue+is%3Aopen+label%3Avim">the |
|
open issues</a> and see which ones you can solve.</p> |

<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> |
