<span id="config-file"></span><h2>The Config file<a class="headerlink" href="#the-config-file" title="Permalink to this headline"></a></h2>
<p>The default configuration file file for Terminator is stored in the
standard path for configuration files. It can be found at:</p>
<div class="highlight-python"><div class="highlight"><pre>${HOME}/.config/terminator/config
</pre></div>
</div>
<p>It is human readable, and can be edited if you are are careful. This
is not generally recommended though, and you are, of course, strongly
advised to make a backup before making manual changes.</p>
<p>There are many more specific details in the manual page:</p>
<div class="highlight-python"><div class="highlight"><pre>man terminator_config
</pre></div>
</div>
</div>
<div class="section" id="debugging">
<span id="id2"></span><h2>Debugging<a class="headerlink" href="#debugging" title="Permalink to this headline"></a></h2>
<p>There is inbuilt debugging features in Terminator. The simplest is to
start Terminator from another terminal with the option <code class="docutils literal"><span class="pre">-d</span></code>. This
will dump many debug statements to the launch terminal.</p>
<div class="admonition note">
<p class="first admonition-title">Note</p>
<p class="last">If the DBus is active in any other Terminator, then by
default your attempt to launch with debug will launch
a new window under the already running process. To prevent
this you can use the <code class="docutils literal"><span class="pre">-u</span></code> option which will disable the
DBus interaction for the debugged instance of Terminator.</p>
</div>
<p>There is a lot of output, and a great deal of it will typically not
be related to the area you are looking into. There are two more
options that can be passed that limit the amount of debug lines to
classes or methods of interest. See <a class="reference internal" href="#command-line-options-debugging"><span>Debugging options</span></a>
for the detail.</p>
<img alt="_images/context_open_debug_tab.png" class="align-right" src="_images/context_open_debug_tab.png" />
<p>The final facility is to start a debug server by passing <code class="docutils literal"><span class="pre">-dd</span></code> (this
is the same as <code class="docutils literal"><span class="pre">-d</span> <span class="pre">-d</span></code>) which will start a debug server. With this
setting a fourth item, <strong>Open Debug Tab</strong>, also appears in the second
part of the <a class="reference internal" href="gettingstarted.html#context-menu"><span>The Context Menu</span></a>, as highlighted in the image to the
right.</p>
<p>Selecting it will give the following new tab with dedicated debug
terminal:</p>
<img alt="_images/debug_tab.png" src="_images/debug_tab.png" />
<p>This prompt is a standard Python interactive prompt, but this is
connected to the Terminator instance. You can explore the applications
data structures, classes, etc. and can even call functions and methods.</p>
<p>Alternatively, instead of launching this tab, you could connect to the
debug server from a different window. This requires that you search
back through the debug output for the line containing &#8220;listening on&#8221;.
Here you will see the port number, and you can simply use:</p>
<div class="highlight-python"><div class="highlight"><pre>$ telnet localhost &lt;port&gt;
</pre></div>

<p>Whichever method you use the debug output is also dumped
into this terminal, even though it is already there in
the launching terminal. This can get rather annoying,
and seems counter-productive to me, so a way to turn
off the output in the debug console may be added. In
the meantime you can use:</p>
<div class="highlight-python"><div class="highlight"><pre><span class="gp">&gt;&gt;&gt; </span><span class="kn">from</span> <span class="nn">terminatorlib</span> <span class="kn">import</span> <span class="n">util</span>
<span class="gp">... </span><span class="n">util</span><span class="o">.</span><span class="n">DEBUG</span><span class="o">=</span><span class="bp">False</span>
</pre></div>
</div>
<p class="last">This should turn off the output, and let you explore the
internal structure more easily.</p>

<div class="admonition warning">
<p class="first admonition-title">Warning</p>
<p class="last">Using the <code class="docutils literal"><span class="pre">-dd</span></code> option will make the <a class="reference internal" href="#dbus"><span>DBus</span></a>

will hang the main application.</p>
</div>
<p>The debug options and their usage are detailed
<a class="reference internal" href="#command-line-options-debugging"><span>here</span></a>.</p>
</div>
<div class="section" id="dbus">
<span id="id3"></span><h2>DBus<a class="headerlink" href="#dbus" title="Permalink to this headline"></a></h2>
<p>DBus is a standardized form of IPC, or Inter-Process Communication.
More detail about the internals of DBus can be found at the
<a class="reference external" href="http://www.freedesktop.org/wiki/Software/dbus/">freedesktop.org</a> for DBus.</p>
<p>In Terminator we currently use DBus for two tasks:</p>
<ul>
<li><p class="first">Only run one instance of Terminator</p>
<p>The first instance will create the server. The second instance will
fail to create the server, so it will request the first instance to
create a new window (or new tab with <code class="docutils literal"><span class="pre">--new-tab</span></code>).</p>
</li>
<li><p class="first">Enable <a class="reference internal" href="#remotinator"><span>Remotinator</span></a></p>
</li>
</ul>
<p>Running a single instance of Terminator will cause problems if you
are trying to launch a <a class="reference internal" href="layouts.html#layouts"><span>layout</span></a>, when an instance is
already running, so when configuring a program, script or menu item
to launch a layout, you need to remember to include the <code class="docutils literal"><span class="pre">-u</span></code> option
that will disable the DBus for that instance. <a class="reference internal" href="layouts.html#layout-launcher"><span>The Layout Launcher</span></a>
does this for you, and as a result any launched layout is running
without DBus, and cannot be controlled with DBus.</p>
<div class="admonition note">
<p class="first admonition-title">Note</p>
<p class="last">There is quite some scope for improving this. I have a vague
notion of a single master server and multiple instance
servers, to improve the interaction between DBus and
layouts.</p>

<div class="section" id="remotinator">
<span id="id4"></span><h2>Remotinator<a class="headerlink" href="#remotinator" title="Permalink to this headline"></a></h2>
<p>Remotinator is a minimal wrapper around making DBus calls, and is
typically run from <em>within</em> a Terminator terminal. This is not
strictly necessary, but if not you will have to do some extra work
to determine the valid UUID of a current terminal and pass it as the
<code class="docutils literal"><span class="pre">TERMINATOR_UUID</span></code> environment variable, or as the value to the
<code class="docutils literal"><span class="pre">-u</span></code>/<code class="docutils literal"><span class="pre">--uuid</span></code> option. Remotinator is called within Terminator
with:</p>
<div class="highlight-python"><div class="highlight"><pre>$ remotinator &lt;command&gt;
</pre></div>
</div>
<p>or with one of the following:</p>
<div class="highlight-python"><div class="highlight"><pre>$ remotinator --uuid &lt;UUID&gt; &lt;command&gt;
$ TERMINATOR_UUID=&lt;UUID&gt; remotinator &lt;command&gt;
$ export TERMINATOR_UUID=&lt;UUID&gt;; remotinator &lt;command&gt;
</pre></div>
</div>
<p>to force the UUID, or call it from outside Terminator.</p>

<p>Calling Remotinator without a command or with the <code class="docutils literal"><span class="pre">-h</span></code> will print
the options and available commands to the terminal.</p>
<div class="admonition note">
<p class="first admonition-title">Note</p>
<p class="last">Because a layout (unless launched from the command line as
as the first instance) is normally launched as a separate
instance requiring the <code class="docutils literal"><span class="pre">-u</span></code>, Remotinator will not work
within layouts. As mentioned in the <a class="reference internal" href="#dbus"><span>DBus</span></a> section,
this has the potential to be improved upon.</p>
</div>
<p>There is a lot of scope for expanding this feature, and it is relatively
simple to do, so is an ideal task for dipping ones toes.</p>
