<h1 id="reading-books"><a class="header" href="#reading-books">Reading Books</a></h1>
|
|
<p>This chapter gives an introduction on how to interact with a book produced by mdBook.
|
|
This assumes you are reading an HTML book.
|
|
The options and formatting will be different for other output formats such as PDF.</p>
|
|
<p>A book is organized into <em>chapters</em>.
|
|
Each chapter is a separate page.
|
|
Chapters can be nested into a hierarchy of sub-chapters.
|
|
Typically, each chapter will be organized into a series of <em>headings</em> to subdivide a chapter.</p>
|
|
<h2 id="navigation"><a class="header" href="#navigation">Navigation</a></h2>
|
|
<p>There are several methods for navigating through the chapters of a book.</p>
|
|
<p>The <strong>sidebar</strong> on the left provides a list of all chapters.
|
|
Clicking on any of the chapter titles will load that page.</p>
|
|
<p>The sidebar may not automatically appear if the window is too narrow, particularly on mobile displays.
|
|
In that situation, the menu icon (three horizontal bars) at the top-left of the page can be pressed to open and close the sidebar.</p>
|
|
<p>The <strong>arrow buttons</strong> at the bottom of the page can be used to navigate to the previous or the next chapter.</p>
|
|
<p>The <strong>left and right arrow keys</strong> on the keyboard can be used to navigate to the previous or the next chapter.</p>
|
|
<h2 id="top-menu-bar"><a class="header" href="#top-menu-bar">Top menu bar</a></h2>
|
|
<p>The menu bar at the top of the page provides some icons for interacting with the book.
|
|
The icons displayed will depend on the settings of how the book was generated.</p>
|
|
<div class="table-wrapper"><table><thead><tr><th>Icon</th><th>Description</th></tr></thead><tbody>
|
|
<tr><td><i class="fa fa-bars"></i></td><td>Opens and closes the chapter listing sidebar.</td></tr>
|
|
<tr><td><i class="fa fa-paint-brush"></i></td><td>Opens a picker to choose a different color theme.</td></tr>
|
|
<tr><td><i class="fa fa-search"></i></td><td>Opens a search bar for searching within the book.</td></tr>
|
|
<tr><td><i class="fa fa-print"></i></td><td>Instructs the web browser to print the entire book.</td></tr>
|
|
<tr><td><i class="fa fa-github"></i></td><td>Opens a link to the website that hosts the source code of the book.</td></tr>
|
|
<tr><td><i class="fa fa-edit"></i></td><td>Opens a page to directly edit the source of the page you are currently reading.</td></tr>
|
|
</tbody></table>
|
|
</div>
|
|
<p>Tapping the menu bar will scroll the page to the top.</p>
|
|
<h2 id="search"><a class="header" href="#search">Search</a></h2>
|
|
<p>Each book has a built-in search system.
|
|
Pressing the search icon (<i class="fa fa-search"></i>) in the menu bar, or pressing the <code>S</code> key on the keyboard will open an input box for entering search terms.
|
|
Typing some terms will show matching chapters and sections in real time.</p>
|
|
<p>Clicking any of the results will jump to that section.
|
|
The up and down arrow keys can be used to navigate the results, and enter will open the highlighted section.</p>
|
|
<p>After loading a search result, the matching search terms will be highlighted in the text.
|
|
Clicking a highlighted word or pressing the <code>Esc</code> key will remove the highlighting.</p>
|
|
<h2 id="code-blocks"><a class="header" href="#code-blocks">Code blocks</a></h2>
|
|
<p>mdBook books are often used for programming projects, and thus support highlighting code blocks and samples.
|
|
Code blocks may contain several different icons for interacting with them:</p>
|
|
<div class="table-wrapper"><table><thead><tr><th>Icon</th><th>Description</th></tr></thead><tbody>
|
|
<tr><td><i class="fa fa-copy"></i></td><td>Copies the code block into your local clipboard, to allow pasting into another application.</td></tr>
|
|
<tr><td><i class="fa fa-play"></i></td><td>For Rust code examples, this will execute the sample code and display the compiler output just below the example (see <a href="../format/mdbook.html#rust-playground">playground</a>).</td></tr>
|
|
<tr><td><i class="fa fa-eye"></i></td><td>For Rust code examples, this will toggle visibility of "hidden" lines. Sometimes, larger examples will hide lines which are not particularly relevant to what is being illustrated (see <a href="../format/mdbook.html#hiding-code-lines">hiding code lines</a>).</td></tr>
|
|
<tr><td><i class="fa fa-history"></i></td><td>For <a href="../format/theme/editor.html">editable code examples</a>, this will undo any changes you have made.</td></tr>
|
|
</tbody></table>
|
|
</div>
