3.37 Miscellaneous

break-on-editor-error Editor Variable

Default value: nil

Specifies whether an editor:editor-error signals a Lisp error, or whether it just displays a message in the Echo Area.

Room Editor Command

Arguments: None
Key sequence: None

Displays information on the current status of the memory allocation for the host computer.

Toggle Showing Line Numbers Editor Command

Arguments: None
Key sequence: None

Toggle Showing Line Numbers toggles whether line numbers are shown in the current window. The actual appearance of the line numbers is controlled from the CAPI side by the initargs for capi:editor-pane or by capi:editor-pane-set-line-numbers-appearance.

Note: Showing line numbers requires that the current buffer counts newlines, which most buffers do. When toggling turns on line numbers, it ensures that the current buffer counts newlines. However, switching to a buffer that does not count newlines, which happens when the buffer is very large, does not ensure counting newlines. If you want to see line numbers in such a buffer, you need to use the command Toggle Count Newlines to switch counting newlines on in the current buffer. Note that this slows the display (which is why it is not done automatically).
