 This option is deprecated in favor of using the `rulerfmt` option (see below). List of information shown in status line ruler. Currently supported information types are 'acc', 'progress', 'selection', 'filter', 'ind', 'df' and names starting with 'lf_'. `acc` shows the pressed keys (e.g. for bindings with multiple key presses or counts given to bindings). `progress` shows the progress of file operations (e.g. copying a large directory). `selection` shows the number of files that are selected, or designated for being cut/copied. `filter` shows 'F' if a filter is currently being applied. `ind` shows the current position of the cursor as well as the number of files in the current directory. `df` shows the amount of free disk space remaining. Names starting with `lf_` show the value of environment variables exported by lf. This is useful for displaying the current settings (e.g. `lf_selmode` displays the current setting for the `selmode` option). User defined options starting with `lf_user_` are also supported, so it is possible to display information set from external sources.

 Format string of the ruler shown in the bottom right corner. Special expansions are provided, '%a' as the pressed keys, '%p' as the progress of file operations, '%m' as the number of files to be cut (moved), '%c' as the number of files to be copied, '%s' as the number of selected files, '%f' as the filter, '%i' as the position of the cursor, '%t' as the number of files shown in the current directory, '%h' as the number of files hidden in the current directory, and '%d' as the amount of free disk space remaining. Additional expansions are provided for environment variables exported by lf, in the form `%{lf_<name>}` (e.g. `%{lf_selmode}`). This is useful for displaying the current settings. Expansions are also provided for user defined options, in the form `%{lf_user_<name>}` (e.g. `%{lf_user_foo}`). The `|` character splits the format string into sections. Any section containing a failed expansion (result is a blank string) is discarded and not shown.
