Code editor: Various operations

Overview

The code editor is the editor where the developers spend most of their time.

This help page presents the different options useful for the common operations:

Highlighting selected elements.
Finding code.
Selection in the code editor.
Operations on lines of code.
Alignment on " = " and "is".
Automatic addition of quotes, brackets or parentheses.
Switching a text to upercase/lowercase.
Displaying the description window of the element whose code is displayed.
Moving procedures or methods.
Creating a procedure with the keyboard.

Highlighting selected elements

In the code editor, whenever the cursor is positioned on an identifier (variable, procedure, data file, etc.), all uses of this identifier are highlighted in the current code.

Similarly, if the mouse cursor is positioned on a block statement (IF, THEN, ELSE, FOR, END, LOOP, WHEN EXCEPTION ON, etc.), the different elements of this block are highlighted.

Remark: When the secondary keywords (ELSE, END, etc.) are hovered by the mouse cursor, the associate condition is displayed in a tooltip.

Finally, the current line can be easily identified via dots used to highlight the current line.

All these options can be modified if necessary.

To modify the highlighting options:

Display the configuration window of code editor: on the "Home" tab, in the "Environment" group, expand "Options" and select "Options of the code editor".
In the "Code" tab, select the following options if necessary:
- "Highlight the blocks of code (IF/THEN/END, brackets, ...)".
- "Highlight the current line".
- "Highlight the declaration and the uses of the variable".
Validate.

Remark: All the colors used to highlight the elements can be configured in the "Coloring" tab of the configuration window of code editor.

Finding code

To find an element in the code editor, all you have to do is use the "Find/Replace" pane, enabled via Ctrl + F.

To perform an immediate search on an element found in the code editor, all you have to do is press Ctrl F3 on an element of code editor (the "Find/Replace" pane being displayed).

Pressing Ctrl + F3:

fills the search control with the word onto which the cursor is positioned.
triggers the search.
highlights in the code all the occurrences found and positions on the first occurrence.

The F3 and Shift + F3 keys allow you to navigate from an occurrence to another one via the keyboard.

Search in a selection

The code editor allows you to perform a search (and a replacement) in a selection.

If a selection exceeding one line is active, the search is automatically performed in this selection.

When performing a search in a selection, the searched word is highlighted in the code.

F3 and Shift + F3 allow you to go from one occurrence to another.

Finding and accessing an event

The code editor allows you to find and access an event of the current element: window, page, report, ...

On the "Code" tab, in the "Navigation" group, type the event you want to find.
Remark: To automatically display the list of events, use Alt + C.
Select the desired event in the list. It is automatically displayed in the code editor.

Selection in the code editor

Selecting lines of code

To perform a simple selection:

A simple click positions the cursor.
A double click selects the word.
A triple click selects the line.
A quadruple click selects the entire text.

During a selection in the code editor, the coloring of the code is kept.

Rectangular selection

You can select a horizontal or vertical rectangular text area in the code editor. This area can be copied/cut and pasted.

To perform a rectangular selection:

Position the cursor at the beginning of the area to select.
Press the Alt key and keep it down.
Press the left mouse button and select the desired area.

The area can then be copied/cut via the context menu.

Remark: When the area is pasted to another rectangular area, the copied text keeps its format.

Selection by level of blocks

You have the ability to perform a selection by level of code blocks.

To perform a selection by level of blocks:

Position the cursor in the block to select.
Press Ctrl + Alt + Up arrow to select the block found above the cursor. Repeat this operation as many times as necessary.
Press Ctrl + Alt + Down arrow to deselect the block found above the cursor. Repeat this operation as many times as necessary.
