| <h1>Content assist</h1> |
| |
| <p>In the C/C++ editor, when you enter a letter combination in the editor, |
| right-click and click <b>Content Assist</b>. A list of code elements and code |
| templates that start with the letter combination that you typed is displayed.</p> |
| |
| <h2>Code Completion</h2> |
| |
| <p>Content assist provides code completion assistance while you code from within |
| the body of a method or a function. For the current project |
| and any referenced projects, a list is displayed of the elements that begin with the |
| letter combination you entered in the order shown below:</p> |
| |
| <ul> |
| <li>Global variables</li> |
| <li>Global functions</li> |
| <li>Global enumerations</li> |
| <li>Global structs</li> |
| <li>Global classes</li> |
| <li>Global unions</li> |
| <li>Global macros</li> |
| </ul> |
| |
| <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. Newly created |
| elements in your current or referenced project(s) must be saved before they will |
| appear in the Content Assist list.</p> |
| |
| <h2>Code Templates</h2> |
| |
| <p>Code templates are frequently used sections of code that you can create and |
| then save for reuse. The Content Assist feature also provides access to code |
| templates. Code Template names beginning |
| with the letter combination you entered are displayed in a list in alphabetical |
| order followed by code elements. You can then select a code template from the list and |
| it is inserted directly |
| into your code.</p> |

| |
| <p>For example, the code template <samp>do - while statement</samp> contains the code:</p> |
| |
| <p><samp>do {<br> |
| ${cursor}<br> |
| } while (${condition});</samp></p> |
| |
| <p> When you select the <samp>do</samp> code template from the list, the |
| following is inserted in your code:</p> |
| |
| <p> <samp> |
| do {<br> |
| } while (condition);</samp></p> |
| |
| <p>A selection of common code templates are already defined. These can be browsed in |
| <b>Window > Preferences > C/C++ > Code Templates</b>.</p> |
| |
| <p>You can create, import and, export code templates.</p> |
