&kdevelop; contains a large number of little tools that help you to perform
9
certain task. Most of them are realized as plugins. That means, if you do not
10
need a plugin, you can disable it.</para>
11
<para>That also means, if you are looking for a functionality that should be there
12
and isn't, then maybe it's implemented in a plugin and that plugin is disabled.
13
For example, in the file menu there is a Quick Open feature, but only if
14
it's enabled in the Project - Project Options dialog.
17
<para>Technically, plugins are based on the KDevPlugin class defined in
18
lib/interfaces/kdevplugin.h. The following is taken from a comment from there.</para>
21
KDevPlugin is the base class for all KDevelop plugins.
22
A plugin is a component which is loaded into KDevelop shell at startup or by request.
23
A plugin has a scope that can be either:
25
<listitem><simpara>Core</simpara></listitem>
26
<listitem><simpara>Global</simpara></listitem>
27
<listitem><simpara>Project</simpara></listitem>
31
<para>Core plugins are global plugins which offer some important "core" functionality and thus
32
are not selectable by user in plugin configuration pages.</para>
34
<para>Global plugins are plugins which require only shell to be loaded and do not operate on
35
KDevProject interface and/or do not use project wide information.
36
For example, the uimode plugin allows a developer to select which user interface they wish to use.
39
<para>Project plugins require a project to be loaded and are usually loaded/unloaded along with the project.
40
If a plugin operates on project-related information then it is a project plugin.
41
The Automake Manager, for example, only needs to be active when an Automake based project is currently loaded.
44
<para>As stated above, core plugins cannot be disabled. Global plugins can be
45
enabled/disabled in <menuchoice><guimenu>Settings</guimenu>
46
<guimenuitem>Configure KDevelop...</guimenuitem></menuchoice>
47
under <guibutton>Plugins</guibutton>.
48
Project plugins can be
49
enabled/disabled in <menuchoice><guimenu>Project</guimenu>
50
<guimenuitem>Project Options...</guimenuitem></menuchoice>
51
under <guibutton>Plugins</guibutton>.
52
Active plugins can have many effects on KDevelop.
53
Depending on their function, they may add extra menus, extra menu items, extra tool buttons, etc.
56
<para>Plugins which are disabled do not clutter your menus and are not loaded
61
<para>The following plugin list is generated by a small script
62
(listplugins.sh) written by Volker Paul. All plugins have a .desktop file
63
where information such as name and comments are written.
64
If in the following these comments are not very useful,
65
it is because the plugin authors made them this way.</para>
66
<para>The plugins are grouped by scope (Core, Global, Project).</para>

<para>In the following, some of the plugins will be discussed in detail.</para>
226
<title>The <command>abbrev</command> Plugin</title>
227
<indexterm zone="plugin-tools"><primary><command>abbrev</command></primary></indexterm>
230
This plugin expands abbreviations into frequently used code snippets. It is
231
activated by pressing <keycombo action="simul">&Ctrl;
232
<keycap>Space</keycap></keycombo>. For example, when you enter
233
<literal>"ife"</literal> into a C++ in the editor and press
234
<keycombo action="simul">&Ctrl;<keycap>Space</keycap></keycombo>, you obtain
235
an <literal>if-else</literal> code template and save some key strokes. The set
236
of supported abbreviations depends on the programming language of the edited
237
file. For example, for PHP you will obviously be interested in other code
238
templates than for &Java;.
243
The set of code templates is configurable. If the plugin is enabled, you can see
244
which ones are available in the <menuchoice><guimenu>Settings</guimenu>
245
<guimenuitem>Configure KDevelop...</guimenuitem></menuchoice>
246
dialog under <guibutton>Abbreviations</guibutton>.
251
<formalpara id="KDevFilter">
252
<title>The <command>filter</command> Plugin</title>
253
<indexterm zone="plugin-tools"><primary><command>filter</command></primary></indexterm>
256
This offers two features. If you select <menuchoice><guimenu>Tools</guimenu>
257
<guimenuitem>Execute command</guimenuitem></menuchoice>, you can enter a shell
258
command. The output of this command is inserted into the editor buffer when
259
you hit the <guibutton>Start</guibutton> button.
264
A related feature is available under
265
<menuchoice><guimenu>Tools</guimenu><guimenuitem>Filter selection through
266
command...</guimenuitem></menuchoice>. In order to use this, you must
267
select a text area in the editor. If you now enter a shell command and hit
268
the <guibutton>Start</guibutton> button, the command is started and the
269
selection used as the standard input for it. The standard output of the
270
command is then inserted into the editor, replacing the selection.
274
For example, if you write documentation, you frequently have to refer
275
to menu items. To do this correctly for e.g. the Copy command in the
276
Edit menu, you have to write:
277
<programlisting><menuchoice><guimenu>Edit</guimenu><guimenuitem>Copy</guimenuitem></menuchoice></programlisting>
278
This is cumbersome, so you'd rather just write "Edit - Copy"
279
and let the computer do the tagging.
280
Here is how you can do it.
281
You write a little shell script called mef you put e.g. in your home's bin directory:
282
<programlisting>sed s/"^\(.*\) - \(.*\)\$"/"<menuchoice><guimenu>\1<\/guimenu><guimenuitem>\2<\/guimenuitem><\/menuchoice>"/</programlisting>
283
Don't forget to make it executable.
284
That's all. Now, in your documentation .docbook source, you write "Edit - Copy".
285
You select this text you just wrote, choose
286
<menuchoice><guimenu>Tools</guimenu><guimenuitem>Filter selection through
287
command...</guimenuitem></menuchoice> and call ~/bin/mef.
288
Instantly "Edit - Copy" is replaced by
289
<programlisting><menuchoice><guimenu>Edit</guimenu><guimenuitem>Copy</guimenuitem></menuchoice></programlisting>
297
<title>The &doxygen; Plugin</title>
298
<indexterm zone="plugin-tools"><primary>&doxygen;</primary></indexterm>
299
<indexterm zone="plugin-tools"><primary>documentation tool</primary></indexterm>
300
<indexterm zone="plugin-tools"><primary>API documentation</primary></indexterm>
303
This one helps you to use the &doxygen; API documentation tool
304
(<ulink url="http://www.doxygen.org"/>). You can select
305
<menuchoice><guimenu>Project</guimenu>
306
<guimenuitem>Run Doxygen</guimenuitem></menuchoice> to generate API
307
documentation for your current project, based on the configuration given by
308
the file <filename>Doxyfile</filename> in your project directory.
313
Furthermore, you can configure &doxygen; in the
314
<menuchoice><guimenu>Project</guimenu>
315
<guimenuitem>Project options...</guimenuitem></menuchoice> dialog. This dialog
316
is very similar to the &doxywizard; tool.
322
<title>The &ctags; Plugin</title>
323
<indexterm zone="plugin-tools"><primary>&ctags;</primary></indexterm>
326
Although the class browser gives you extensive insight into the symbols and
327
classes of your project, you may also want to use the ctags tool. In particular,
328
this one supports a lot more language than the class browser.
333
You activate this plugin under <menuchoice><guimenu>Tools</guimenu>
334
<guimenuitem>CTags...</guimenuitem></menuchoice>. When you start it the first
335
time, you will be asked to generate a search database first. When you accept
336
this, the &ctags; program will be started and will create a file named
337
<filename>tags</filename> in your project directory. This is a text file containing
338
all symbols of your source files.
342
You can search in the symbol database in two ways: when the
343
<guilabel>Regular expression match</guilabel> box is checked, the text you
344
enter will be interpreted as a regular expression (POSIX flavor) and matched
345
with the existing symbols. For example, the text <literal>.*Widget</literal>
346
will search for all symbols ending with <literal>Widget</literal>. If the
347
box is not checked, the search will be verbatim.
351
When searching, you will get a list of the matched symbols, accompanied with
352
the line numbers where they are defined. You jump to the respective point by
353
clicking on the list.
357
For some languages, &ctags; distinguishes different kinds of symbols. For
358
example, Python has classes and functions. You can selectively search only
359
for classes by checking the respecting kinds in the dialog.
363
The symbol database is normally not updated when your sources change.
364
Consequently, after a while the line numbers will not be correct anymore
365
and newly added classes and functions will be missing. Therefore you should
366
update the <filename>tags</filename> file in regular intervals by pressing
367
the button <guibutton>Regenerate</guibutton>.
373
<title>The <command>astyle</command> Plugin</title>
374
<indexterm zone="plugin-tools"><primary><command>astyle</command></primary></indexterm>
375
<indexterm zone="plugin-tools"><primary><application>Artistic Style</application></primary></indexterm>
376
<indexterm zone="plugin-tools"><primary>indentation</primary></indexterm>
379
Astyle is a plugin for formatting of sourcecode according to a specified set of rules.
386
<title>The <command>regexptest</command> Plugin</title>
387
<indexterm zone="plugin-tools"><primary><command>regexptest</command></primary></indexterm>

<indexterm zone="plugin-tools"><primary>debugging</primary><secondary>regular expressions</secondary></indexterm>
389
<indexterm zone="plugin-tools"><primary>regular expressions</primary><secondary>debugging</secondary></indexterm>
392
Designing with regular expressions can be hard work. Often the first try at an
393
expression matches too many strings. In particular, when working with a
394
compiled language, the turnaround times when debugging a regular expression
395
can be awkward. The regexptest plugin allows you to directly explore the
396
changes in a regular expression. It is activated by choosing
397
<menuchoice><guimenu>Tools</guimenu>
398
<guimenuitem>Debug Regular Expression...</guimenuitem></menuchoice>.
403
In the flavor group box, you can choose the flavor of the regular expression
404
engine used. Currently supported is the flavor defined in the POSIX standard,
405
which is used by the &grep; program, and the extended POSIX syntax used by the
410
When you enter an expression, you get immediate feedback about any syntax
411
errors in it. By entering a text under <guilabel>Test string</guilabel>,
412
you can see whether the expression matches this string. In particular, if
413
your regular expression includes groups, such as <literal>([a-z])</literal>,
414
the content of the matched subgroups will be shown in a list box.
