Use these settings to configure the SIL Manager according to your preferences:

|  |
| --- |
| **Editor appearance** |
| **Theme** | Choose the SIL Manager visual appearance and color scheme. |
| **Font size** | Adjust editor text size. |
| **File type handling** |
| **Treat files with no extension as** | Sets the default file type for files without an extension. Default is SIL, but you can change this to any supported file type. |
| **Treat files with unknown extension as** | Sets the default file type for files with unrecognized extensions. The default is Text, but you can change this to any supported file type. |
| **Content and behavior** |
| **Placeholder** | Customize default text in empty files. The default is "Code goes here...". Useful for organizational reminders like scripting standards or file descriptions. |
| **Enable autocomplete** | Turn function name suggestions on/off. Suggests SIL functions while typing and shows required parameters. Press Enter to insert highlighted suggestion. |
| **Live autocomplete** | Enable real-time suggestions while typing. When disabled, suggestions only appear when pressing Ctrl+Space.<br>> ℹ️ For more keyboard shortcuts, see [this page](https://appfire.atlassian.net/wiki/spaces/PSJC/pages/490997515). |
| **Display options** |
| **Show gutter** | Control visibility of the gray column on the left containing line numbers, error messages, and fold widgets. |
| **Show line numbers** | Display/hide line numbers in the gutter without removing the entire gutter. |
| **Show fold widgets** | Enable/disable code folding controls that allow hiding (folding) and showing (unfolding) code sections by toggling the widget. |
| **Show print margin** | Display/hide the 80-character margin line that indicates where text might get cut off when printed. Also serves as a visual reminder that long lines should be broken into multiple lines for readability. The margin position cannot be adjusted. |
| **Show non-printing characters** | Display/hide invisible characters like line breaks/returns and tab marks. Useful for inspecting data files with unwanted characters. |
| **Highlight active line** | Shade the line where the cursor is positioned to help track location while reading or editing.<br>> ℹ️ The highlight color is controlled by the selected theme and cannot be configured separately. |
| **Show file type tags** | Display/hide file type indicators (SIL, TEXT) in the file tree. |
| **Code formating ** |
| **Use spaces for tabs** | When enabled (default), uses multiple spaces (4 by default) instead of tab characters (ASCII character #9) for indentation. This ensures consistent appearance across different editors since there is no standard definition of tab size. |
| **Tab size** | Number of character spaces a tab represents (4 by default). This provides adequate indentation visibility for code, compared to the traditional 8-space definition which is designed for written text rather than code. |
