<h2 id="how-to-compile-and-execute-the-text-editor-tfe.">How to compile and execute the text editor ‘tfe’.</h2>
<p>First, source files are shown in the later subsections. How to download them is written at the end of the <a href="sec15.html">previous section</a>.</p>
<p>The following is the instruction of compilation and execution.</p>
<ul>
<li>You need meson and ninja.</li>
<li>Set environment variables if necessary. If you have installed gtk4 from the source and you preferred the option <code>--prefix $HOME/local</code> (see <a href="sec2.html">Section 2</a>), type <code>. env.sh</code> to set the environment variables.</li>
</ul>
<pre><code>$ . env.sh</code></pre>
<ul>
<li>change your current directory to <code>src/tfe5</code> directory.</li>
<li>type <code>meson _build</code> for configuration.</li>
<li>type <code>ninja -C _build</code> for compilation. Then the application <code>tfe</code> is built under the <code>_build</code> directory.</li>
<li>type <code>_build/tfe</code> to execute it.</li>
</ul>
<p>Then the window appears. There are four buttons, <code>New</code>, <code>Open</code>, <code>Save</code> and <code>Close</code>.</p>
<ul>
<li>Click on <code>Open</code> button, then a FileChooserDialog appears. Choose a file in the list and click on <code>Open</code> button. Then the file is read and a new Notebook Page appears.</li>
<li>Edit the file and click on <code>Save</code> button, then the text is saved to the original file.</li>
<li>Click <code>Close</code>, then the Notebook Page disappears.</li>
<li>Click <code>Close</code> again, then the <code>Untitled</code> Notebook Page disappears and at the same time the application quits.</li>
</ul>
<p>This is a very simple editor. It is a good practice for you to add more features.</p>
