<h1>Content Assist</h1>
|
|
|
|
<p>Content Assist is a set of tools built into the CDT that can reduce the number of keystrokes you must
|
|
type to create your code. The Content Assist plug-in consists of several components that forecast what
|
|
a developer will type, based on the current context, scope, and prefix.</p>
|
|
|
|
<h2>Code completion</h2>
|
|
|
|
<p>Content assist provides code completion anywhere in the document. For the current project a list is
|
|
displayed of the elements that begin with the letter combination you entered, and
|
|
the relevance of each proposal is determined in the following order:</p>
|
|
|
|
<ul>
|
|
<li>Fields</li>
|
|
<li>Variables</li>
|
|
<li>Methods</li>
|
|
<li>Functions</li>
|
|
<li>Classes</li>
|
|
<li>Structs</li>
|
|
<li>Unions</li>
|
|
<li>Namespaces</li>
|
|
<li>Enumerations</li>
|
|
</ul>
|
|
|
|
You trigger the Code completion feature when you call Content Assist (such as when you type <span class="typewriter">Ctrl+Space</span>), but it is auto-activated when you type
|
|
<Q><strong>.</strong></Q>, <Q><strong>-></strong></Q> or <Q><strong>::</strong></Q>.</p>
|
|
|
|
<p><img src="../images/contentAssist_example.png" alt="C++ example showing Code Assist popup"></p>
|
|
|
|
<p>You can view the signature of each item on the list in a pop-up by pointing to it. You can then select an item in the list to insert it directly into your code. </p>
|
|
|
|
<h2>Templates</h2>
|
|
|
|
<p>You can create and save templates for frequently used sections of code, which will be inserted according to scope. The Content Assist feature also provides quick access to code
|
|
templates.</p>
|
|
|
|
<p>When you enter a letter combination in the C/C++ editor, and type <span class="typewriter">CTRL+SPACE</span> (or right-click and click <strong>Content Assist</strong>), a
|
|
list of code elements and templates that start with the letter combination that you typed is displayed.</p>
|
|
|
|
<p>You can then select a template from the list and it is inserted directly into your code.</p>
|
|
|
|
<img src="../images/editor_c_codetemplates_use.png" alt="C++ example showing Code Assist popup"></p>
|
|
|
|
<p>For example, the template <samp>do while statement</samp> contains the following code:</p>
|
|
|
|
<p><img src="../images/codetemplates_example.png" alt="Code Template showing do-while example"></p>
|
|
|
|
<p> When you select the <samp>do</samp> template from the list, you insert the following code:</p>
|
|
|
|
<p><pre>do {
|
|
} while (condition);</pre></p>
|
|
|
|
|
|
<p>If the completion engine finds only one proposal in your templates, that proposal is inserted at the current cursor position.
|
|
For example if you create a new .cpp file and type <span class="typewriter">mai+CTRL+SPACE</span> the following code is inserted at the cursor location:</p>
|
|
<p><pre>int
|
|
main(int argc, char **argv) {
|
|
|
|
}</pre></p>
|
|
|
|
<h2>No Completions</h2>
|
|
|
|
<p>If you invoke Content Assist, but no completions are found a message will be displayed on the status to inform you that the Content Assist parser has timed out.</p>
