A ---- highlight group can be supplied either as a string or as an ---- integer, the latter which can be obtained using ---- `nvim_get_hl_id_by_name()`. ---- • virt_text_pos : position of virtual text.

If "undo_restore" is ---- false, the extmark is deleted instead. ---- • priority: a priority value for the highlight group, sign ---- attribute or virtual text. For virtual text, item with ---- highest priority is drawn last. For example treesitter ---- highlighting uses a value of 100. ---- • strict: boolean that indicates extmark should not be placed ---- if the line or column value is past the end of the buffer or ---- end of the line respectively. Defaults to true. ---- • sign_text: string of length 1-2 used to display in the sign ---- column. ---- • sign_hl_group: name of the highlight group used to highlight ---- the sign column text. ---- • number_hl_group: name of the highlight group used to ---- highlight the number column. ---- • line_hl_group: name of the highlight group used to highlight ---- the whole line. ---- • cursorline_hl_group: name of the highlight group used to ---- highlight the sign column text when the cursor is on the ---- same line as the mark and 'cursorline' is enabled. ---- • conceal: string which should be either empty or a single ---- character.
