[[Property:title|Class name auto complete]]

[[Property:weight|3]]
|

EiffelStudio editor offers the possibility to complete class names automatically. This means that when the user types " ''a_variable: AN_INCOMPLETE_CLASS_NAME''" and then triggers the auto-complete, the editor will propose a list of possible valid class names. <br/>
|
||||
To be more precise, a window will pop up and display the list of classes that match ''AN_INCOMPLETE_CLASS_NAME''. The user can accept the suggested name, choose another name (in the list or not), or simply cancel the auto-complete.

|

To trigger the auto complete, press the key combination "Ctrl+Shift+Space" or click on '''Complete class name''' in the '''Advanced''' sub-menu of the [[Edit menu commands|menu]] . If automatic completion is possible, there are two cases : if only one name matches, this name will be inserted in the editor. If there are no matching names or several ones a window will appear. This window will contain a text field and a list. The text field will be filled with the beginning of the class name that was entered. The first item in the list, if any, will be selected. <br/>
|
||||
To complete your code with the selected item, press "Enter" or "Ctrl+Space". <br/>
|
||||
To choose another item, use keyboard Up and Down arrows or the mouse. You can also modify the content of the text field. The list will be updated automatically. To validate your choice, press "Enter" or "Ctrl+Space". If there is no selected item, the content of the text field will be inserted. <br/>

To cancel the auto-complete, press "Esc" at any time.

[[Property:title|Feature call auto complete]]

[[Property:weight|2]]
|
||||
EiffelStudio editor now offers the possibility to complete feature calls automatically. This means that when the user types " ''an_identifier.an_incomplete_feature_name''" and then triggers the auto-complete, the editor will propose a list of possible feature names correct in this situation. <br/>
|
||||
To be more precise, a window will pop up and display the list of features that can be called on ''an_identifier'' and that match ''an_incomplete_feature_name''. The user can accept the suggested name, choose another name (in the list or not), or simply cancel the auto-complete.
|
||||
|
||||
[[Image:editor-auto-completion-window]]

To trigger the auto complete, press the key combination "Ctrl+Space" or click on '''Complete word''' in the '''Advanced''' sub-menu of the [[Edit menu commands|menu]] .

{{tip| '''Tips''': }}
|
||||
* If the selected feature is a query, you can call the auto-complete again right after the previous completion. There is no need to type a dot.
|
||||
* You can call the auto-complete without an identifier. The auto-complete window will then show the features of the current class.
|
||||
* The keyboard shortcut for automatic completion can be changed in the [[Keyboard shortcuts preferences|editor preferences]] .
|
||||
* Typing a non-alphanumeric character in the completion window automatically closes it. You can therefore type '.', ' ' or '(' to close the completion window and start typing the next token straight away.
|
||||
|
||||
{{note| '''Notes''': }}
|
||||
* Only identifiers that were already defined when the class was compiled for the last time can be completed, except for local entity names that can always be completed.
|
||||
* Only compiled features will appear in the auto-complete window.
|
||||
* By default, features from class ANY will be ignored by the auto-complete window. This can be changed in the [[General Editor Preferences|editor preferences]] .

[[Property:title|Syntax auto complete]]

[[Property:weight|1]]
|

Syntax auto-complete in EiffelStudio editor is twofold :
|
||||
*
|
||||
The editor can close brackets ("(", "{" and "[") and quotes(""", "'" and "`") automatically. This feature is disabled by default. It can be activated in the editor preferences.
|
||||

The editor can complete syntactic structures or part of them. The auto-complete is triggered when "Enter" or "Space" keys are pressed after a reserved word included in the following list:

[[Property:title|Cursor moves]]
|
||||
[[Property:weight|1]]
|
||||
There are two ways to position the cursor in EiffelStudio editor: you can use either the mouse or the keyboard.
|
||||
|
||||
If you choose to use the mouse, just click in the text where you want the cursor to be moved. If the text is not entirely visible, you can use the scroll bar at the bottom and on the left of the edition zone to display the part you are interested in.
|
||||
|
||||
The keys that you may use to move the cursor in EiffelStudio editor are "Home", "End", "Page up", "Page Down" and the four arrows. Pressing "Home" will make the cursor go to the beginning of the line. Pressing "End" will move the cursor to the end of the line. You can use "Page Up" to move the cursor one page closer to the beginning of the text. Pressing "Page down" will position the cursor one page further. <br/>
|
||||
Left and Right arrows can be used to move respectively to the character on the left or on the right of current position. Up and Down arrows allow you to move the cursor to the previous and next lines.
|
||||
|
||||
{{tip| '''Tip''': By maintaining "Ctrl" pressed as you use Left and Right arrows, you will move the cursor to the next or previous word instead of the next or previous character. }}

* If you triple click in the edition area, then the pointed line will be selected. If you do not release the mouse button after the third click, you will be able to select text line by line.
|
||||
* A quadruple click will select the entire text (this is an option that you can [[Editor Preferences|modify]] in the preferences dialog).
