<title>Common commandline options</title>

<para>
All GTK+ applications support a number of standard commandline
options. These are removed from <literal>argv</literal> by 
gtk_init(). Modules may parse and remove further options.
</para>

<formalpara>
<title><systemitem>--gtk-module <replaceable>module</replaceable></systemitem></title>

<para>
A list of modules to load in addition to those specified in the 
<envar>GTK_MODULES</envar> environment variable.
</para>
</formalpara>

<formalpara>
<title><systemitem>--g-fatal-warnings</systemitem></title>

<para>
Make GTK+ abort on all warnings.

<formalpara>
<title><systemitem>--gtk-debug <replaceable>options</replaceable></systemitem></title>

<para>
A list of <link linkend="GTK-Debug-Options">debug options</link> 
to turn on in addition to those specified in the <envar>GTK_DEBUG</envar> 
environment variable. 
This option is only available if GTK+ has been configured with
<option>--enable-debug=yes</option>.
</para>
</formalpara>

<formalpara>
<title><systemitem>--gtk-no-debug <replaceable>options</replaceable></systemitem></title>

<para>
A list of <link linkend="GTK-Debug-Options">debug options</link> 
to turn off.
This option is only available if GTK+ has been configured with
<option>--enable-debug=yes</option>.
</para>
</formalpara>

<para>
The following options are really used by GDK, not by GTK+, but we
list them here for completeness nevertheless.
</para>

<formalpara>
<title><systemitem>--class <replaceable>class</replaceable></systemitem></title>

<para>
Sets the program class; see gdk_set_program_class(). 
</para>
</formalpara>

<formalpara>

<para>
Sets the program name.
</para>
</formalpara>

<title><systemitem>--gdk-debug <replaceable>options</replaceable></systemitem></title>

<para>
A list of <link linkend="GDK-Debug-Options">debug options</link> 
to turn on in addition to those 
specified in the <envar>GDK_DEBUG</envar> environment variable. 
This option is only available if GTK+ has been configured with
<option>--enable-debug=yes</option>.
</para>
</formalpara>

<formalpara>
<title><systemitem>--gdk-no-debug <replaceable>options</replaceable></systemitem></title>

<para>
A list of <link linkend="GDK-Debug-Options">debug options</link> 
to turn off.

<option>--enable-debug=yes</option>.
</para>
</formalpara>

<formalpara>
<title><systemitem>--display <replaceable>display</replaceable></systemitem></title>

<para>
The name of the X display to open instead of the one specified
in the <envar>DISPLAY</envar>. 
This option is only available if GTK+ has been configured with
<option>--gdk-target=x11</option>.
</para>
</formalpara>

<formalpara>
<title><systemitem>--sync</systemitem></title>

<para>
Makes all X requests synchronously. This is a useful option for 
debugging, but it will slow down the performance considerably.
This option is only available if GTK+ has been configured with
<option>--gdk-target=x11</option>.
</para>
</formalpara>

<formalpara>
<title><systemitem>--gxid-host <replaceable>host</replaceable></systemitem></title>

<para>
The host to contact the <application>gxid</application> daemon on; overwrites 
the <link linkend="GXID"><envar>GXID_HOST</envar></link> environment variable.

</para>
</formalpara>

<formalpara>
<title><systemitem>--gxid-port <replaceable>port</replaceable></systemitem></title>

<para>
The port for the connection to <application>gxid</application>; overwrites

<title>Environment variables</title>

<para> 
GTK+ inspects a number of environment variables in addition to standard
variables like <envar>LANG</envar>, <envar>PATH</envar>, <envar>HOME</envar> 
or <envar>DISPLAY</envar>; mostly to determine paths to look for certain files.
</para>

<formalpara id="GTK-Debug-Options">
  <title><envar>GTK_DEBUG</envar></title>

  <para>
  If GTK+ has been configured with <option>--enable-debug=yes</option>,
  this variable can be set to a list of debug options, which cause GTK+
  to print out different types of debugging information.

  </para>
</formalpara>

<formalpara>
  <title><envar>GTK_MODULES</envar></title>

  <para>
    A list of modules to load.
  </para>
</formalpara>

<formalpara>
  <title><envar>GTK_MODULE_PATH</envar></title>

  <para>
    A list of directories to search for modules before the default module 
    directory, which is <filename>&lt;libdir&gt;/gtk-2.0/modules</filename>.
    (If <envar>GTK_EXE_PREFIX</envar> is defined, &lt;libdir&gt; is 
    <filename>$GTK_EXE_PREFIX/lib</filename>. Otherwise it is the libdir
    specified when GTK+ was configured, usually 
    <filename>/usr/local/lib</libdir>.) 
    For each directory in the list, GTK+ actually looks first in 
    a subdirectory named after the version number of GTK+, then in the 
    directory itself and finally in the system-specific library path.
  </para>
</formalpara>

<formalpara>
  <title><envar>GTK_IM_MODULE</envar></title>

  <para>
    Specifies an IM module to use in preference to the one determined
    from the locale. 
  </para>
</formalpara>

<formalpara>
  <title><envar>GTK_IM_MODULE_PATH</envar></title>

  <para>
    Specifies the path where GTK+ looks for IM modules. This environment 
    variable overwrites the <literal>im_module_path</literal> specified in the 
    RC files, which in turn overwrites the default
    value <filename>$lt;libdir$gt;/gtk-2.0/immodules/&lt;version&gt;</filename>
    (where &lt;version&gt; is the GTK+ version, and &lt;libdir&gt; is as 
    explained above).
  </para>
</formalpara>
 
<formalpara>
  <title><envar>GTK_IM_MODULE_FILE</envar></title>

  <para>
    Specifies the file listing the IM modules to load. This environment
    variable overwrites the <literal>im_module_file</literal> specified in 
    the RC files, which in turn overwrites the default value 
    <filename>&lt;sysconfdir&gt;/gtk-2.0/gtk.immodules</filename>
    (&lt;sysconfdir&gt; is the sysconfdir specified when GTK+ was configured, 
     usually <filename>/usr/local/etc</libdir>.)
  </para>
<formalpara>

<formalpara>
  <title><envar>GTK_RC_FILES</envar></title>
  
  <para>
    Specifies a list of RC files to parse instead of the default ones;
    see <link linkend="gtk-Resource-Files">Resource Files</link>.
</formalpara>

<formalpara>
  <title><envar>GTK_EXE_PREFIX</envar></title>

  <para>
    If set, GTK+ uses <filename>$GTK_EXE_PREFIX/lib</filename> instead of 
    the libdir configured when GTK+ was compiled.
  </para>
</formalpara>

<formalpara>
  <title><envar>GTK_DATA_PREFIX</envar></title>

  <para>
    If set, makes GTK+ use <filename>$GTK_DATA_PREFIX<filename>
    instead of the prefix configured when GTK+ was compiled.
  </para>
</formalpara>

<para>
The following environment variables are used by GdkPixbuf, GDK or
Pango, not by GTK+ itself, but we list them here for completeness
nevertheless.
</para>

<formalpara>
  <title><envar>GDK_PIXBUF_MODULEDIR</envar></title>

  <para>
    Specifies the directory to look for GdkPixbuf loader modules. 
    By default, GdkPixbuf looks for its loaders in 
    <filename>&lt;libdir&gt;/gtk-2.0/&lt;version&gt;/loaders</filename>.
  </para>
 </formalpara>

  </para>
</formalpara>

<formalpara id="GXID">
  <title><envar>GXID_HOST</envar> and <envar>GXID_PORT</envar></title>

  <para>
    The host and port to contact the <application>gxid</application> daemon on. 
    <application>gxid</application> is only necessary on X servers which 
    don't support using the pointer and extension devices at once, and is
    only built if GTK+ is configured with <option>--with-xinput=gxi</option>. 
    The <application>XFree86</application> X servers don't have this 
    restriction.
  </para>
</formalpara>

<formalpara>
  <title><envar>GDK_USE_XFT</envar></title>

  <para>
    If this variable is set to 1, GTK+ will use the Pango Xft backend instead
    of the X backend when possible (i.e. when the X server supports the XRender
    extension and Pango has been built with Xft support).
