<title>The Configuration Dialogue</title>
|
|
|
|
<para>
|
|
The configuration dialogue is the main tool for setting parameters required by &kapp;, or adjusting the user's preferences. The dialogue is displayed the first time &kapp; is run, and can be invoked later by using the <menuchoice><guimenu>Settings</guimenu><guimenuitem>Configure KScope...</guimenuitem></menuchoice> menu command.
|
|
</para>
|
|
|
|
<para>
|
|
The dialogue is composed of several pages, each of which handles a different set of parameters.

<title>The Programmes Page</title>
|
|
|
|
<para>
|
|
&kapp; serves as a front-end to several console-based programmes: <application>Cscope</application>, <application>Ctags</application> and <application>Dot</application> (which is part of the <application>Graphviz</application> suite). Since &kapp; invokes these programmes directly, without using a shell, it cannot determine their paths. Therefore, it is required to inform &kapp; of the paths where the relevant executable files reside. Note that &kapp; needs the full path to each programme, along with the name of the executable.
|
|
</para>
|
|
|
|
<para>
|
|
Another parameter required by &kapp; is whether <application>Cscope</application> supports the <option>-v</option> command line option. This is a relatively new feature, added to <application>Cscope</application> in version 15.5. It allows &kapp; to display accurate progress information during time-consuming operations, such as building the cross-reference database, or running a long query. It is highly recommended that you upgrade <application>Cscope</application> to a version that supports the <option>-v</option> option, as the user experience of &kapp; is much improved with it. However, if you choose to use an older version of <application>Cscope</application>, make sure the check-box for using the <option>-v</option> option is cleared.
|
|
</para>
|
|
|
|
<para>
|
|
You can determine whether your version of <application>Cscope</application> supports this option by running <userinput><option>cscope</option> <option>-h</option></userinput>.

</para>

The easiest way to configure programme paths is by using the automated script provided with &kapp;. This script can be activated by clicking the <guibutton>Guess...</guibutton> button. Once invoked, the script looks for the required programmes (using the shell's <filename>which</filename> utility). The script also makes sure that the found executables adhere to the standards required by &kapp; (e.g., that <application>Ctags</application> is the one provided by <application>Exuberant-Ctags</application> and that <application>Dot</application> supports the <option>-Tplain</option> command-line option). &kapp; uses the results of the script to adjust the values in the dialogue's controls.
|
|
</para>
|
|
|
|
<note>
|
|
<para>The script will not override paths already set by the user. Instead, it will only verify the validity of these paths. For the script to determine paths automatically, the relevant text fields in the dialogue need to be cleared.</para>
