Editor Appearance

Options on this panel control the appearance of the editor (excluding colors and fonts).

Show Line Numbers

Enabling this options activates a line number listing for files in the editor.

Show Vertical Line

Displaying a vertical line is useful for determining when a single line of text is approaching a limit. For example, the Fortran 90 standard dictates that the maximum length of a single line is 132 characters. Enabling this guide can make development easier.

In fixed-format Fortran mode, the editor will automatically show lines delineating the sixth and seventh columns.

Indentation Guides

Indentation guides are useful in lining up indented text within a Fortran source file. In the case of large loops, for example, where the loop contents are indented, the guide can be used to determine where the dedented loop closing should be place.

Word Wrap

Enabling this option causes lines wider than the editor tab to wrap to the next line. However, this wrapping is performed for display purposes only; it is not reflected in the saved file. When a line does wrap and line numbers are enabled, a small arrow will appear on subsequent display lines to indicate that they are actually continuations of the previous line.

Enable Code Folding

Code folding in the editor is depicted as small bars in the editor’s margin. When bars are clicked and this option is enabled, code structures (conditionals, loops, procedures, etc.) can be collapsed to a single line while editing. This behavior can be helpful when editing code surrounding long, embedded control structures.

Caret Width

This number specifies the width of the text cursor within the editor tab. This number can be either 1, 2, or 3, with 3 being the thickest.
