Usage

Use Responsive Breakpoints

local breakpoint = { l = 1, m = 2, s = 3 }
local breakpoints = { [breakpoint.l] = math.huge, [breakpoint.m] = 128, [breakpoint.s] = 80 }

stl:add_item(nut.buf.filename({
  prefix = " ",
  suffix = " ",
  config = {
    modifier = ":.",
    [breakpoint.m] = {
      format = function(name)
        return table.concat({ vim.fn.pathshorten(vim.fn.fnamemodify(name, ":h")), "/", vim.fn.fnamemodify(name, ":t") })
      end,
    },
    [breakpoint.s] = { modifier = ":t", format = false },
  },
}))
