Folding

Defines the structuring of the code by indentations.

When you select an indentation, you can expand or collapse the indentation section using a plus or minus sign to the left of the first line of each section.

• Indentation: TwinCAT combines all lines that are indented relative to the previous line in one indentation unit.
• Explicit: You explicitly use comments to identify the code section to be grouped in an indentation unit: The section must be preceded by a comment containing 3 opening curly brackets "{{{", and followed by a comment containing 3 closing curly brackets "}}}". The comments can contain additional text. Sample:

Word wrap

• Soft: The line break occurs at the edge of the editor window if 0 is entered for the wrap margin.
• Hard: The line break occurs after the number of characters specified at the wrap margin.

Tab width

Number of characters

Keep tabs

: The space that you have inserted with the [ Tab ] key will not subsequently be converted by TwinCAT into individual spaces.

Indent width

If you have activated Smart or Smart with code completion for the Auto Indent option, TwinCAT inserts the number of spaces at the beginning of the line.

Auto Indent

• Do not indent automatically
• Block: A new line automatically adopts the indentation of the previous line.
• Intelligent: Lines that follow a line containing a keyword (for example, VAR) automatically indent by the specified indent width.
• Smart with code completion: Indentation as with the Smart option, in addition TwinCAT inserts the final keyword (e.g. END_VAR).

Highlight current line

: The line in which the cursor is positioned is highlighted.

Matching brackets

: If the cursor is positioned before or after a bracket within a code line, TwinCAT marks the corresponding closing or opening bracket with a frame.

Line markers

: TwinCAT marks the end of each editor line with a small horizontal line after the last character of the line (including spaces).

Wrap guide:

: If a soft or hard line break is enabled, the defined wrap guide is displayed by a vertical line.

Show bracket scope

:Bracketing comprises the lines between the keywords that open and close a construct, such as IF and END_IF.

If the option is enabled and the cursor is positioned before, after or in one of the keywords of a construct, the bracketing area is indicated by a square bracket in the margin.

Focused border color

Color of the dividing line between the margin and the input area

Unfocused border color

Color of the dividing line between the margin and input area of the currently inactive part of the window

Mouse actions

One of the following actions can be assigned to each of the specified mouse actions or mouse button shortcuts. TwinCAT executes the actions when you execute the mouse action on the plus or minus sign before the header line of a bracketed area:

• None: The mouse action does not trigger any action.
• Select fold: TwinCAT selects all the lines of the bracketed area.
• Toggle fold: TwinCAT opens or closes the bracketed area, or, in case of nested bracketing, the first level of the bracketed area.
• Toggle fold fully: TwinCAT opens or closes all levels of a nested bracketed area.
