Deleting marks in picker

[ciza99]

Hello, how could I delete the selected marks in the marks picker? Is this not available by default and I would have to extend the functionality? It confused me since I can select the marks with tab.

Note

picker:find doesn't work as expected with the vim_marks finder because it is bound to the current window.

Note

Deleted items are still selected after picker:find.

          delmark = function(picker)
            local cursor = picker.list.cursor
            local deleted = {}
            for _, it in ipairs(picker:selected { fallback = true }) do
              local ok = pcall(vim.api.nvim_del_mark, it.label)
              if ok then
                table.insert(deleted, it)
              end
            end
            picker:close()
            local picker_new = Snacks.picker.marks()
            picker_new.list:view(cursor - #deleted)

@drowning-cat thanks, this works, even though only for capital marks, since they are cross-file. I guess with lowercase marks it does not work because your in the picker window / buffer :/

I've updated the code.
