</div>
<h2 id="create-a-launchjson-file">Create a <code translate="no" v-pre>launch.json</code> file</h2>
<p>Navigate to the Debug view in VSCode, and click on &quot;create a launch.json file&quot; link.
In the dropdown menu, select &quot;pocketpy&quot;.</p>

    <img src="../../static/debugger/launch_json.png" alt="launch_json" class="max-w-full h-auto rounded-image-rounded border-image-border border-image-border-width" width="1654" height="630" />
    <figcaption class="caption">launch_json</figcaption>
</figure>
</p>
<p>Then a default <code translate="no" v-pre>launch.json</code> file will be created in the <code translate="no" v-pre>.vscode</code> folder
with a sample pocketpy debug configuration.</p>
<h2 id="how-does-it-work">How does it work?</h2>
<p>pocketpy provides a C-API <code translate="no" v-pre>py_debugger_waitforattach</code>,
which starts a debug server and waits for the VSCode extension to attach.
When the debugger is attached, the program will continue to run.</p>
<ul>
<li>If you are using pocketpy&#x27;s standalone executable <code translate="no" v-pre>main.exe</code>, you can pass <code translate="no" v-pre>--debug</code> flag to it. This will automatically call <code translate="no" v-pre>py_debugger_waitforattach(&quot;127.0.0.1&quot;, 6110)</code> before running your program.</li>
<li>If you are embedding pocketpy as a library, you need to call <code translate="no" v-pre>py_debugger_waitforattach</code> manually in your C/C++ code.</li>
</ul>
<h2 id="configuration">Configuration</h2>
<ul>
<li><code translate="no" v-pre>type</code>: must be <code translate="no" v-pre>pocketpy</code></li>
<li><code translate="no" v-pre>request</code>: can be <code translate="no" v-pre>attach</code> or <code translate="no" v-pre>launch</code></li>
<li><code translate="no" v-pre>name</code>: the name of this configuration</li>
<li><code translate="no" v-pre>port</code>: the port number of the debug server, must match the one in <code translate="no" v-pre>py_debugger_waitforattach</code></li>
<li><code translate="no" v-pre>host</code>: the host of the debug server, must match the one in <code translate="no" v-pre>py_debugger_waitforattach</code></li>
<li><code translate="no" v-pre>sourceFolder</code>: the root folder of your python source code, default to <code translate="no" v-pre>${workspaceFolder}</code>. However,
sometimes you may run your program from a subfolder, in this case you need to set <code translate="no" v-pre>sourceFolder</code> to the correct path. If this is not set correctly, breakpoints will not be hit.</li>
<li><code translate="no" v-pre>program</code>: (for launch mode only) the path to the executable file which calls <code translate="no" v-pre>py_debugger_waitforattach</code>, e.g. the pocketpy standalone executable <code translate="no" v-pre>main.exe</code>.</li>
<li><code translate="no" v-pre>args</code>: (for launch mode only) the arguments to pass to the executable file, e.g. <code translate="no" v-pre>--debug</code> and the script path if you are using <code translate="no" v-pre>main.exe</code>.</li>
<li><code translate="no" v-pre>cwd</code>: (for launch mode only) the working directory to launch the executable file, default to <code translate="no" v-pre>${workspaceFolder}</code>.</li>
</ul>
<h3 id="for-attach-mode">For attach mode</h3>
<p>In this mode, you need to start your pocketpy program manually which must call <code translate="no" v-pre>py_debugger_waitforattach</code> first.
After the program starts, you can let VSCode attach to the debug server.</p>
