is the model for <a class="link" href="class-gtksourceview2.html" title="gtksourceview2.View"><code class="classname">gtksourceview.View</code></a>
widgets. It extends the <code class="classname">gtk.TextBuffer</code>
object by adding features necessary to display and edit source code: syntax highlighting, bracket matching and markers.
It also implements support for undo/redo operations.
</p><p>
To create a <a class="link" href="class-gtksourcebuffer2.html" title="gtksourceview2.Buffer"><code class="classname">gtksourceview2.Buffer</code></a>

Like a <code class="classname">gtk.TextMark</code>, a
<code class="classname">gtksourceview2.Marker</code>
can be anonymous if the passed <em class="parameter"><code>name</code></em> is <code class="literal">None</code>.
Also, the buffer owns the markers so you shouldn't unreference it.
</p><p>
Marks always have left gravity and are moved to the beginning of the line when the user deletes the line they were in.
Also, if the user deletes a region of text which contained lines with markers, those are deleted.
</p><p>
Typical uses for marks are bookmarks, breakpoints, current executing instruction indication in a source file, etc..

The <code class="methodname">iter_forward_search</code>() function searches forward for <em class="parameter"><code>str</code></em>
and returns a tuple containing <code class="classname">gtk.TextIter</code>
objects that point at the start and end locations of the match.
The search will not continue past limit. Note that a search is a linear or O(n) operation,
so you may wish to use limit to avoid locking up your UI on large buffers.
</p><p>
If the gtksourceview2.SOURCE_SEARCH_VISIBLE_ONLY flag is present, the match may have invisible text
interspersed in str. i.e. str will be a possibly-noncontiguous subsequence of the matched range.
similarly, if you specify gtksourceview2.SOURCE_SEARCH_TEXT_ONLY, the match may have pixbufs or
child widgets mixed inside the matched range. If these flags are not given, the match must be exact;
the special 0xFFFC character in str will match embedded pixbufs or child widgets. If you specify the
gtksourceview2.SOURCE_SEARCH_CASE_INSENSITIVE flag, the text will be matched regardless of what case it is in.
</p><p>
Same as <code class="methodname">gtk.TextIter.forward_search</code>(),
but supports case insensitive searching.
