<h1 id="the-watch-command"><a class="header" href="#the-watch-command">The watch command</a></h1>
|
||
|
|
<p>The <code>watch</code> command is useful when you want your book to be rendered on every
|
||
|
|
file change. You could repeatedly issue <code>mdbook build</code> every time a file is
|
||
|
|
changed. But using <code>mdbook watch</code> once will watch your files and will trigger a
|
||
|
|
build automatically whenever you modify a file; this includes re-creating
|
||
|
|
deleted files still mentioned in <code>SUMMARY.md</code>!</p>
|
||
|
|
<h4 id="specify-a-directory"><a class="header" href="#specify-a-directory">Specify a directory</a></h4>
|
||
|
|
<p>The <code>watch</code> command can take a directory as an argument to use as the book's
|
||
|
|
root instead of the current working directory.</p>
|
||
|
|
<pre><code class="language-bash">mdbook watch path/to/book
|
||
|
|
</code></pre>
|
||
|
|
<h4 id="--open"><a class="header" href="#--open">--open</a></h4>
|
||
|
|
<p>When you use the <code>--open</code> (<code>-o</code>) option, mdbook will open the rendered book in
|
||
|
|
your default web browser.</p>
|
||
|
|
<h4 id="--dest-dir"><a class="header" href="#--dest-dir">--dest-dir</a></h4>
|
||
|
|
<p>The <code>--dest-dir</code> (<code>-d</code>) option allows you to change the output directory for the
|
||
|
|
book. Relative paths are interpreted relative to the book's root directory. If
|
||
|
|
not specified it will default to the value of the <code>build.build-dir</code> key in
|
||
|
|
<code>book.toml</code>, or to <code>./book</code>.</p>
|
||
|
|
<h4 id="specify-exclude-patterns"><a class="header" href="#specify-exclude-patterns">Specify exclude patterns</a></h4>
|
||
|
|
<p>The <code>watch</code> command will not automatically trigger a build for files listed in
|
||
|
|
the <code>.gitignore</code> file in the book root directory. The <code>.gitignore</code> file may
|
||
|
|
contain file patterns described in the <a href="https://git-scm.com/docs/gitignore">gitignore
|
||
|
|
documentation</a>. This can be useful for
|
||
|
|
ignoring temporary files created by some editors.</p>
|
||
|
|
<p><em>Note: Only <code>.gitignore</code> from book root directory is used. Global
|
||
|
|
<code>$HOME/.gitignore</code> or <code>.gitignore</code> files in parent directories are not used.</em></p>
